Our Far South Roadshow

Tuesday, July 17th, 2012 | hamvi58p | No Comments

Earlier this year Gareth Morgan led the Our Far South expedition down through the subantarctic islands and Southern Ocean to Antarctica. Among the crew were 10 of New Zealand’s top experts in the region and 40 everyday New Zealanders. The purpose of the trip was to raise awareness about ‘Our Far South’, its importance and the issues facing the area including climate change, the race for resources and conservation. One of the projects that has come out of the trip is the so-called Million Dollar Mouse campaign to eradicate mice from the Antipodes Islands. See www.milliondollarmouse.org.nz

What they discovered on the voyage was fascinating and Gareth is now embarking on a national speaking tours to share his experience and further our aim of raising awareness about the region. All proceeds from the roadshow will go to the Million Dollar Mouse campaign.

The National Tour starts in Tauranga on 30th July, visits 9 cities throughout New Zealand, ending in Invercargill on 16th August.

More details and tickets are available on the website. www.ourfarsouth.org/events/national-tour.aspx

“Chemistry Matters” – Once more into the world of hydronium and logarithm; but never mind the mole

Once more into the world of hydronium and logarithm; but never mind the mole

By Associate Professor Allan Blackman: This article was orignally published in the Otago Daily Times on Wednesday 4 July 2012.

Last month I attempted to explain the meaning of pH in around 500 words. To my chagrin, I found that this was an impossible task. The column was littered with arcane terms like ‘hydronium ion’ and ‘logarithm’, and numbers like 0.0000001 and 1 × 10^-7, things that do not make for easy reading. So let’s take up where I left off and see if I can’t do a better job in explaining what pH actually means.

What was hopefully obvious from last month’s column was that pH is far from a simple concept. For starters, it is a logarithmic function. In simple terms, this means that a change of 1 pH unit corresponds to a 10-fold change in the hydronium ion concentration – at the risk of upsetting the chemistry purists, one could say that a solution of pH 3 is 10 times as acidic as one of pH 4. To put this in a more understandable context, suppose we had 1 litre of a solution of pH 3 – if we added 9 litres of water to this (i.e. a 10-fold dilution) the final solution would have a pH of 4.

The useful pH scale ranges from 0 (a very acidic solution) to 14 (a very basic solution). Because of its logarithmic nature, this means that it spans a hydronium ion concentration range of 1 × 10¹⁴, or 100,000,000,000,000, between these pH values. To give some idea of the pH values of common substances, lemon juice, for example, has a pH around 2.3, orange juice, around 3.5, milk, around 6.7, seawater, around 8, household ammonia, around 11.5, and oven cleaner can be as high as 13, depending on its composition. Although it is supposedly common knowledge that pure water at 25 °C has a pH of 7.00, measurement of the pH of a sample of any water under all but the most stringently controlled conditions will yield a value somewhere between 5 and 6; this is because the water sample will contain dissolved carbon dioxide from the air, which renders the water very slightly acidic through formation of small amounts of ‘carbonic acid’.

So this is where we get to the importance of pH. Nature has evolved so that many of its important chemical reactions, particularly those that occur in living systems, are optimised to occur at particular pH values. If the pH of the system becomes too high or too low, then critical chemical reactions are impeded, and this can be fatal for the organism. For example, normal human blood has a pH between 7.35 and 7.45 – if our blood pH lowered to 7 or increased to 8, we would probably die. Nature has therefore developed a series of chemical species we call buffers, which ensure that the pH of blood does not change significantly.

Sadly, despite all I have written here, a true appreciation of exactly what pH means is contingent on understanding the mole, a chemical concept which is usually first introduced in 6th form (Year 12) Chemistry and is not necessarily understood by all even when University rolls around. My explanation of pH has only scratched the surface and is extremely simplistic – but hopefully it had given you some idea of what pH is all about.

Of course, the fact that pH is conceptually difficult doesn’t stop advertisers telling us that their clients’ products are ‘pH balanced’ ‘pH neutralising’, and other such meaningless terms. Treat all such claims with caution.

“Chemistry Matters” – Radioactivity in you and me

Tuesday, May 22nd, 2012 | hamvi58p | No Comments

Radioactivity in you and me

By Associate Professor Allan Blackman. This article was orignally published in the Otago Daily Times on Friday 18 May 2012.

Late last month, a soccer ball that had washed up on Middleton Island in the Gulf of Alaska, was discovered by a technician at the radar station there. The ball was found to have come from a school in Japan, some 6000 km away, which was struck by the Tsunami of March 11th, 2011. In addition to the enormous amount of debris swept into the Pacific Ocean, the Tsunami also caused extensive damage to the Fukushima nuclear power plant, and released significant amounts of radioactive material into the environment.

It is a tragedy that the cities of Fukushima, Hiroshima, Nagasaki and Chernobyl will for ever be associated with the word “radioactivity”. It is, in my opinion, fair to say that a significant number of people think of radioactivity as resulting solely from the actions of human beings, by way of nuclear power stations or nuclear weapons, and that it didn’t exist prior to the 20th century. So it may come as some surprise to you that your body, my body, and, indeed, the bodies of everybody on planet Earth, are teeming with radioactive atoms, the majority of which derive from a natural source – the element potassium.

Potassium (elemental symbol K) is an essential element for life. Humans require around two to four grams a day, and this is generally obtained from such foods as potatoes, spinach and bananas. But it turns out that, of all the potassium atoms we ingest, a small percentage are radioactive. Natural potassium consists of three isotopes, ³⁹K, ⁴⁰K and ⁴¹K. All three contain 19 positively-charged protons in their nucleus, but differ in the number of neutrons – 20, 21 and 22, respectively. The ⁴⁰K isotope is radioactive, and comprises about 0.012% of all the atoms of potassium on Earth. It has a half-life of just over one billion years, meaning that one half of any sample of ⁴⁰K will disappear over this time, and it decays by emitting beta particles and gamma rays, both of which are potentially harmful to humans.

An ‘average’ 75 kg person contains about 150 g of potassium. Of that 150 g, 0.018 g is due to the radioactive ⁴⁰K isotope. This might not sound much, but when this mass is converted to an actual number of atoms, we find that it corresponds to about 270,000,000,000,000,000,000 atoms of radioactive potassium in the body. That’s a lot. Given the billion year half-life of this isotope, you might perhaps expect that not many of these atoms would decay over our lifetime, but again, you may be surprised to find that around 7000 ⁴⁰K atoms decay per second. Each of these decays can potentially lead to DNA mutation, and there’s absolutely nothing we can do about it! Obviously it is impossible for us to gauge the health effects of these radioactive decays, as it’s rather difficult to prepare a potassium-free human.

Like it or not, natural radioactivity, whether it be in the form of ⁴⁰K, the most abundant radioactive isotope in the body, ¹⁴C, which we ingest primarily through breathing in ^₁₄CO₂ from the air, or literally hundreds of other radioactive isotopes, is ubiquitous, and will always be with us – well, at least for the next few billion years, anyway.

Liver helps ‘set’ body clock

The University of Sydney

Friday, 04 May 2012

A disrupted body clock can cause a higher risk of obesity and diabetes, but this breakthrough suggets a new target for treatments to ‘reset’ the clock.

International travellers, shift workers and even people suffering from obesity-related conditions stand to benefit from a key discovery about the functioning of the body’s internal clock.
Professor Chris Liddle, from the Westmead Millennium Institute for Medical Research, the University of Sydney, worked with a team from the Salk Institute based in California, to demonstrate the importance of circadian receptors found in the brain and the liver. Their findings are published in Nature today.
“The research is important as these are the first core component of the circadian clock identified that can be targeted with drugs, which could provide relief for those affected by disrupted circadian rhythms,” said Professor Liddle.
The circadian clock is an internal daily body clock that controls alertness, appetite, sleep timing and hormone secretions.
“Previously we have known that there are body ‘clocks’ not only in the brain but in most other body tissues including the liver, part of the focus of this study. While the brain clock is mainly cued by light, these other clocks are cued by factors such as exercise and diet as well as receiving nerve and hormone signals from the central clock in the brain.”
People with circadian disturbances tend to have a higher incidence of health concerns such as obesity, diabetes and related metabolic disorders. It is much more than simply a problem of disturbed sleep.
“People tend to think that the clock is just something that happens in the brain but it’s a whole-body issue. Literally you do not feel like exercising and your metabolism slows when you are in a certain part of the cycle. This contributes to obesity-related problems.
“When you fly overseas, not only do you wake up in the middle of the night, you probably notice you want to eat in the middle of the night, and that during the day you have reduced energy. The liver is a key player in the regulation of energy and we now understand quite a bit more how liver genes ‘clock in’ to the circadian cycle.”
Professor Liddle, a liver expert who has worked on liver genes for more than a decade with the Salk Institute, said the team had been able to show that these receptors in the liver were important in controlling the metabolism of fats and other genes related to diet, nutrition, digestion and energy expenditure.
“This is a very exciting discovery. We have now shown that these receptors in the body’s tissues do not have a peripheral role but are core components for setting our body clock that we can potentially use drugs on.
“The promise of this research for the future is that we can specifically target drug treatments at these receptors. The hope is that not only problems like jet lag and disturbed sleep can be more easily managed but other associated health concerns can be addressed more effectively,” Professor Liddle said.

In the news – ‘Super moon’ to rise over New Zealand

Friday, May 4th, 2012 | hamvi58p | No Comments

A “super moon” will rise in New Zealand skies on Sunday.

It will be 14 per cent bigger and 30 per cent brighter than any other full moon this year, the US space agency NASA says.

Known as a “perigee moon”, it occurs when the moon reaches its closest point to Earth.

The full moon will occur at 3.35pm on Sunday, New Zealand time, but will not be visible here until moonrise over New Zealand at 5.23pm.

With a clear sky, it guarantees Sunday night will be a bright one.

NASA says the super moon has a reputation for trouble, causing high tides, making dogs howl and keeping people awake.

The space agency says the best time to look at it is when the moon is near the horizon.

“For reasons not fully understood by astronomers or psychologists, low-hanging moons look unnaturally large when they beam through trees, buildings and other foreground objects.

“This moon illusion will amplify a full moon that’s extra-big to begin with. The swollen orb rising in the east at sunset should seem super indeed.”

Super perigee moons are fairly common, with the moon becoming full within a few hours of its closest approach to Earth about once a year on average.

The last such event occurred on March 19 last year, producing a full moon that was almost 400km closer than this one.

The “super moon” will produce spring tides around New Zealand, with a 3.6 metre high tide at 7.51am on Monday in Auckland.

Maui’s dolphins’ survival near ‘point of no return’

Monday, April 30th, 2012 | hamvi58p | No Comments

CLOSE TO EXTINCTION: A Maui dolphin and her calf.

The survival of the critically endangered Maui’s dolphin species will soon be “past the point of no return” unless emergency action is taken, an expert says.

What is believed to be a Maui’s dolphin was found dead by a member of the public in Taranaki last week. The dolphin was found on a beach near Pungarehu, south of New Plymouth.

It was collected by the Conservation Department and taken to Massey University for an autopsy.

It is not yet known if the dead dolphin is a Maui, of which only 54 are believed to be left, or a closely related Hector’s dolphin. The latest population survey found a couple of Hector’s mingling further north than usual with Maui’s dolphins.

If confirmed, it would be the second Maui’s dolphin found dead in Taranaki this year. Another, a female, was accidentally killed by a fisherman in January.

Otago University zoology professor Liz Slooten said the species was at a level where any loss would have a huge impact.

“Basically all bets are off already, natural processes could take them away. If we stopped catching them in fishing nets tomorrow we would still hold our breath … so we really need to pull out all the stops or soon we’ll go past the point of no return.”

Set net bans are imposed on the coastline between Dargaville to north Taranaki.

“As a biologist it’s really frustrating. I’ve done surveys there and wrote an article in 2005 to say the Maui is going much further south than the protected area,” Prof Slooten said.

The Fisheries Act included allowances for emergency protection measures to be put in place “literally overnight” in cases of sudden stock declines or unprecedented events, she said.

Submissions on laws to further protect the Maui’s dolphins closed on Friday. The laws want to extend the current ban on set nets along the west coast of the North Island and also extend a marine mammal sanctuary.

The fishing industry will argue against the ban, saying the dolphins have not been seen in the Taranaki area for years.

Keith Mawson, of Egmont Seafoods in Taranaki, earlier told the Seafood Industry Council that a proposal to extend the set net ban was a knee-jerk reaction. A ban would be disappointing for the fishing community, which was being used as a “scapegoat”, he said. By Michelle Robinson and Shane Cowlishaw.

April Update

Friday, April 20th, 2012 | hamvi58p | No Comments

Dear OUASSA students

Knowledge Forum: We have just completed another round of statistics analysis based on the work you are doing in Knowledge Forum. The good news is that some of you are making a genuine effort to involve yourselves in the on-line discussions either by providing interesting notes, building-on and/or annotating the notes of others. However, there are quite a few of you who are not meeting the commitment of just 1 post per week. If you are having technical difficulties getting into Knowledge Forum you need to let us know right away so we can try fix it from this end.

There are a number of different views that you can be contributing. Primarily the focus for you should be on building up project related discussions based in your Project A groups (Marine Science, Zoology, Physics and Maths).

Towards the end of May we will be asking each of you to synthesise your Project A discussions in a Synthesis Post. In this post you will identify the knowledge built for you from the discussion. So you have approximately 4 weeks to get yourselves involved! We will provide the instructions for this task soon.

Don’t forget, there are also views on the main curriculum areas (biology, Chemistry and Physics) where you can find Achievement Objectives, ask questions, request help etc and we will gladly support you. The introductory exercise views on three world problems are still up and running and actively being contributed to be some of you. And there are two more recent views on Knowledge Building and Knowledge Forum Support. You are free to contribute to any or all of these views.

Please remember that the expectation we have of you is one contribution per week! That equates to about 20-30mins input.

Medical animator David Bolinsky presents 3 minutes of stunning animation that show the bustling life inside a cell.

David Bolinsky and his team illustrate scientific and medical concepts with high-drama animation. You’ve never seen the life of a cell quite like this.

Each of us has about 100,000 [kinesins] running around, right now, inside each one of your 100 trillion cells. So no matter how lazy you feel, you’re not really intrinsically doing nothing.” (David Bolinsky)

Studying before bedtime has benefits

Learning Best When You Rest: Sleeping After Processing New Info Most Effective

ScienceDaily (Mar. 23, 2012) — Nodding off in class may not be such a bad idea after all. New research from the University of Notre Dame shows that going to sleep shortly after learning new material is most beneficial for recall.

Notre Dame psychologist Jessica Payne and colleagues studied 207 students who habitually slept for at least six hours per night. Participants were randomly assigned to study declarative, semantically related or unrelated word pairs at 9 a.m. or 9 p.m., and returned for testing 30 minutes, 12 hours or 24 hours later. Declarative memory refers to the ability to consciously remember facts and events, and can be broken down into episodic memory (memory for events) and semantic memory (memory for facts about the world). People routinely use both types of memory every day — recalling where we parked today or learning how a colleague prefers to be addressed.

At the 12-hour retest, memory overall was superior following a night of sleep compared to a day of wakefulness. However, this performance difference was a result of a pronounced deterioration in memory for unrelated word pairs; there was no sleep-wake difference for related word pairs. At the 24-hour retest, with all subjects having received both a full night of sleep and a full day of wakefulness, subjects’ memories were superior when sleep occurred shortly after learning, rather than following a full day of wakefulness.

“Our study confirms that sleeping directly after learning something new is beneficial for memory. What’s novel about this study is that we tried to shine light on sleep’s influence on both types of declarative memory by studying semantically unrelated and related word pairs,” Payne says.

“Since we found that sleeping soon after learning benefited both types of memory, this means that it would be a good thing to rehearse any information you need to remember just prior to going to bed. In some sense, you may be ‘telling’ the sleeping brain what to consolidate.”

Some teams look at the big picture

Wednesday, March 21st, 2012 | hamvi58p | No Comments

By Associate Professor Allan Blackman: This article was orignally published in the Otago Daily Times
on Saturday 10 March 2012. blackman@chemistry.otago.ac.nz

My students do little chemistry. By this, I don’t mean to impugn their reputation by suggesting their work habits aren’t all that they could be. Rather, I’m saying that they do chemistry on a small scale. They measure masses in milligrams or grams, and volumes in millilitres whenever they carry out chemical reactions. There is generally no need to work on larger scales, as no new information will be obtained. Financial considerations also often play a part in determining how much material is used in any reaction – chemicals can be surprisingly expensive!

On the other hand, some researchers do big chemistry, whose scale is limited only by their imaginations (and money again, of course). Big chemistry usually requires the collaboration of lots of research groups around the world and is often aimed at addressing big questions. One such example of big chemistry recently resulted in a group based in the Chemistry Department at the University of Otago, along with workers at NIWA in Wellington, winning the Prime Minister’s Science Prize for 2011. The big question these workers addressed was ‘what can we do to reduce carbon dioxide levels in the atmosphere?’

It is a fact that levels of carbon dioxide in the atmosphere are increasing. This could potentially lead to both an increase in the Earth’s temperature, and the oceans becoming more acidic, neither of which would be beneficial to life on this planet. It therefore makes sense to plan for such eventualities, and investigate ways in which carbon dioxide levels in the atmosphere could be controlled if necessary. And this is where the work of the groups at Otago and NIWA becomes relevant. It had been proposed that phytoplankton in the oceans could potentially absorb significant amounts of carbon dioxide from the atmosphere during photosynthesis, the process by which green plants convert carbon dioxide to organic materials and oxygen. While this hypothesis could potentially be tested in the laboratory, it would really take a large scale experiment to demonstrate its viability.

And a large scale experiment it was. Truly big chemistry. It involved seeding a small area of the Southern Ocean with iron (about 1.7 tonnes!), to encourage the growth of phytoplankton, and then monitoring the changes in carbon dioxide levels, using a variety of methods including satellite surveys. You can imagine the wealth of coordination and cooperation required to carry out such a study. The results were interesting; while it was found that enhanced absorption of carbon dioxide into the ocean did occur in the seeded areas, it was also found that the phytoplankton themselves released other potent greenhouse gases, such as nitrous oxide, into the atmosphere. This demonstrated that such an approach would not be effective at mitigating greenhouse gas levels in the atmosphere.

This might appear at first sight to be a negative result, but thanks to the big chemistry carried out, we now know that we must look for other ways to avert the deleterious effects of greenhouse gases in the atmosphere. The Prime Minister’s Science Prize is worth $500,000. Given that a Nobel Prize is worth $1.8 million, I think that’s pretty generous. Time to get my students working harder…

This website is a great place to spend some time looking into what you are interested in and what tertiary study options are out there for you.

No Major Drama – The smart way to learn about NZ university majors!

www.nomajordrama.co.nz/

The smart way to learn about NZ university majors! Create your own ranking of major subject areas? based on your skills and interests.

No Major Drama helps you learn about majors for Bachelor degrees from across all eight New Zealand universities* and rank them based on your skills and interests.

(*Auckland University of Technology, Lincoln University, Massey University, University of Auckland, University of Canterbury, University of Otago, University of Waikato, Victoria University of Wellington)

No Major Drama is designed to help you answer what’s likely to be one of the most important questions you’ll face in your life: What should I ‘major’ (specialise) in at university?

This question is important because of the lifetime benefits – and costs! – associated with university education. It’s also of national significance given education’s social and economic value and the scarcity of education resources.

Based on your skills and interests, No Major Drama lets you create your own personalised ranking of 181 major subject areas – eg. Accounting, Music, Zoology, etc – representing 730 specific majors for Bachelor degrees from across all eight NZ universities.

(If you are unsure of what ‘majors’ and ‘subject areas’ are, visit our terminology page.)

As well as personalised rankings, No Major Drama provides summaries of each subject area and links to carefully chosen Wikipedia articles, career opportunities, and links to the eight universities’ web pages for all 730 specific majors available in NZ.

No Major Drama is quick and easy to use (5-10 minutes), and you can share your results with your parents and family, school counsellors and friends by email or on Facebook.

Created by Graduate Factory Ltd, No Major Drama is completely free – for individual users and schools. Schools can easily create customised versions of the software for their students.

I got straight E’s in maths, thank you very much for all your help on this website, it really helped me
I just wanted to say a huge thanks for all the help I received from Studyit for my level 1 papers last year (I got 100% excellence!)
Studyit made a huge difference to the way I approached the exam! I tried to make my answers biologically detailed but concise even though I was really stressed for time.
Seems that all us Studyit users found the exam went incredibly well even though 3 News said it was really hard. I think this just goes to show the positive impact of Studyit on our performance
I went into the exam feeling a lot more confident knowing that I had prepared as well as I could – and a great deal of that preparation could not have been done without Studyit. It was so great to have such quick replies to all my questions, even on weekends and holidays.

Studyit gives students more confidence!

Chemistry – Pathologist’s discoveries to dye for

I was feeling a bit poorly a couple of weeks ago, so I crawled from my
sickbed and made one of my relatively infrequent trips to the Doctor, who
prescribed a course of antibiotics. While remaining bedridden and feeling very
sorry for myself, I had occasion to recall the interesting genesis of the first
synthetic antibiotic. It’s all to do with dyes, and a father’s great love for
his daughter.
Up until a couple of hundred years ago, brightly coloured clothes were almost exclusively the domain of the rich, as the dyes used had to be sourced from either plants or animals. The colouration of one of Julius Caesar’s purple robes, for example, reputedly came from the extracts of 10,000 molluscs, while to dye anything crimson required lots and lots of cochineal insects from far-off Mexico.
However, all this changed thanks to William Perkin, who in 1856, at the
ridiculously young age of 18, patented the first synthetic dye, the
purple-coloured mauveine. His discovery changed the chemical industry overnight,
and spurred an enormous amount of research into other synthetic dyes – indeed,
the chemical giant BASF was founded in 1865 for this very purpose.
In 1925, BASF, along with five other chemical companies, merged to form I.G.
Farben (‘Farben’ is an abbreviation of the German word for ‘dye industry’) and
it was to here that the German pathologist Gerhard Domagk took a leave of
absence from his Professorship at the University of Münster in order to further
his studies on bacterial infections. He was working on a virulent form of
streptococcus, and wanted to be able to ‘stain’ the bacteria so they could be
easily visualised. For this, he used a class of simple, highly-coloured
molecules called azo dyes, and found to his surprise that some of these showed
promising activity against the bacteria. Chemical modification of one particular
azo dye gave a molecule called Prontosil, and in 1932, Domagk showed that this
protected mice against lethal doses of streptococci.
While this was a huge breakthrough, it was by no means certain that Prontosil
would be as effective in humans. And here, fate intervened. In 1935, Domagk’s 6
year-old daughter, Hildegard, pricked herself with a needle and suffered a
streptococcal infection – in those days, such infections were often fatal. She
was rushed to the doctor, who recommended amputation of the arm to save her
life. Domagk, aghast at the suggestion, gave her a dose of Prontosil – two days
later the infection had subsided and, soon after, she was discharged from
hospital. This incident, along with other somewhat more controlled clinical
trials, confirmed Prontosil as the world’s first effective synthetic
antibiotic.
Domagk was awarded the Nobel Prize in Physiology or Medicine in 1939.
However, a law passed by the Nazis forbade any German citizen from accepting the
award, and he did not make the journey to Stockholm until 1947. Sadly, while he
was awarded the diploma and the medal, he didn’t receive the monetary portion of
the prize.
While Prontosil was soon overtaken by Penicillin as the antibiotic of choice,
Domagk’s work laid the foundations for all modern synthetic antibiotics. For
this, we should be very grateful.

Biology Scholarship link

Friday, September 2nd, 2011 | hamvi58p | No Comments

You’ll obvioulsy know by now if you are doing Biology Scholarship at the end of the year. If so, as you’ll know already your best preparation is to read as widely as possible on all things biology related. Here is the link to guidelines and exemplars from the NZQA website.

http://www.nzqa.govt.nz/qualifications-standards/awards/scholarship/scholarship-subjects/scholarship-biology

Also, as mentioned in an earlier post, the website that I would most recommend to teachers and students alike is the Teachers Domain site: http://www.teachersdomain.org/collection/k12/sci/. Make some time to have a look at the resources for wider reading, animations, powerpoints etc on all manner of science related topics. This site will really help you with developing wider thinking skills to get your responses in exams up to that Merit and Excellence level that you are all striving for!

Tell your science teacher about the Teachers Domain site and this OUASSA site and make their day!

Isolating Mechanisms

Tuesday, August 16th, 2011 | hamvi58p | No Comments

http://www.teachersdomain.org/resource/tdc02.sci.life.evo.lacewings/

Check out the section called ‘Background Essay’….. brilliant for your revision, here is a sneak peak.

‘When explaining a breakup, couples will often say, “We grew apart,” or “We both changed in different ways.” That’s a good metaphor for how species are formed: members of a population somehow begin to diverge, usually as a result of being geographically separated from each other. Eventually, they can no longer interbreed, and at that point a new species has formed.

Yet if the two groups continued to live near each other, it’s likely that mating attempts between naturally varying members of the two populations would tend to allow the species to merge again. This is called “gene flow” between the two groups. What keeps this from happening, and what allows new species to arise and endure, are what are known as “isolating mechanisms.” These are either behavioral or structural differences between species that make mating impossible……’ see website for remainder of article.
Discussion Questions:

How might different songs keep species of lacewings from interbreeding?

Can you think of other examples of traits or mechanisms that would similarly isolate other closely-related species?

The Origin of Species

This is a great website for those wanting to apply themselves to what has been taught in the classroom. The extract below is the background reading, there are applictaion questions as well as the interactive slide show. A must for serious Biologists and Excellence/Schol. candidates!

http://www.teachersdomain.org/resource/tdc02.sci.life.evo.anorigin/

The term evolution refers to the cumulative change that occurs in populations of organisms over time. Sometimes evolutionary change is so dramatic that different populations of the same species diverge to become two or more distinct species. In the case of a group of birds called honeycreepers, for example, a single species that colonized the Hawaiʻian Islands about 5 million years ago ultimately diverged into 57 different species.

This process, which evolutionary biologists call speciation or adaptive radiation, can happen anywhere. However, it is most clearly demonstrated on geologically young land masses, such as newly formed islands or mountains. In these environments a population of organisms will typically find a set of environmental opportunities and pressures very different from the conditions they experienced in their place of origin. These environmental differences come in many forms and often cause sweeping evolutionary changes in a founding population.

Several environmental factors affect the process of speciation. The structural habitat of an area determines the ease with which creatures are able to move around and find shelter from weather and other organisms. Food, both the type and its availability, dictates the ease with which animals are able to acquire the energy they need to survive and reproduce.

Competition for various resources is another factor that can drive the process of speciation. Competitive pressure can come from organisms of the same species or from organisms of different species. Generally, in highly competitive environments, traits that minimize competition — traits that, for example, allow two different populations to feed on very different types of food — are advantageous.

Another factor that can influence speciation is predation. Predators typically reduce the rate of speciation because they limit other organisms’ access to resources. On newly formed land masses, however, the number of predators is typically lower than on older continents. These younger environments, therefore, provide more opportunities for species to evolve into new and different species

Zoology Students

Tuesday, July 12th, 2011 | hamvi58p | No Comments

Lisa and the Zoology Team have asked that the Zoology students read through the following information prior to their project work.

Dear Zoology students

You will find some activities attached here to help prepare you for the Zoology project during this camp. We will be focusing on invasive species, in particular species found within urban areas. As I’m sure you are all aware, this topic can be quite emotive, particularly when addressing issues of impact on native communities and management and control methods. We have asked you to research a couple of questions related to invasive species, gather some viewpoints on invasive species and control, and then finally to do a bit of research into a specific role. At the end of the project we will be undertaking a role play activity where you will be taking on a specific persona and have to argue your case for control. We do realise that the role you are assigned may not reflect your own personal view point, but sometimes they are actually the easiest to argue!

Just a reminder to make sure you bring warm clothes, sturdy boots and a torch or headlamp for our early morning excursion on the tuesday. Remember its COLD in Dunedin and snow is predicted this week already.

Looking forward to working with you all again.

The Zoology team.

Questions to think about over the holidays

There are many introduced species in New Zealand: >2,000 plant species, 32 mammals, and 33 birds have been introduced. But not all of them are considered to be invaders.

Can you think about the following, and be prepared to discuss when we meet.

What is the definition of an invasive species?

2. What makes an invasive species a pest?

Here are two quotes about possums: think about the implications of these different viewpoints of possums and be prepared to discuss them.

1. This quote is by S. Bracegirdle of Egmont Skins and Hides, in the Taranaki Daily News (June 2011), describing his business which collects dead possums, plucks them for fur to sell to wool factories for possum/wool garments:

“We’re turning a pest into something creative”

2. This quote is by Potts (2009, Society and Animals Vol 17: pp 1-20):

“Possums are positioned not only as unwanted and dangerous foreign invaders but also as unworthy of compassion and deserving of persecution: it is as if possums are responsible for the prejudice and malice they now face”

Finally, please gather three viewpoints from your family or acquaintances on possums as pests and their knowledge of current methods of possum control.

Role Play Exercise

Management and control of invasive species is often a very emotive subject resulting in a wide range of very different viewpoints. It is important that we consider all of these different views when planning and implementing management programmes. This exercise is designed to give you an opportunity to explore some very divergent view points.

Scenario:

It has been proposed by a group of local environmentalists that an area of land, which includes a cluster of farms (some dairy), significant remnants of native vegetation, and including some small urban areas, be managed to be predator-free with the purpose of improving its biodiversity value. Given that it has been recommended that possum management strategies should include the development of community processes that can assist in the design of appropriate strategies, the leader of the group proposing this plan has organised a meeting at which local stakeholders can express their opinions about the concept of the plan and the control methods used.

Each of you has been assigned an identity. Be prepared to make a statement based on your identity and defend your point of view. You need to agree on whether the eradication should go ahead, and the methods used to carry out the eradication. Feel free to immerse yourself in your role!

Roles:

Department of Conservation worker – Alise
Animal Health Board inspector – Rueben
Dairy farmer whose daughter’s dog died after scavenging a possum that had died from 1080 poisoning – Hannah
Fur trapper – Jenny
Animal rights activist and passionate Greenie – Jamie-Leigh
Urban dweller – Ellyce

Do not spend too long on each question. If you have extra time at the end return to the question.
Do not use twink, pencil or red pen.
Cross out mistakes with a single line.
Use diagrams to support your answer. Label clearly.
Read questions twice. Circle key terms.
Do not bulk up an answer. Keep to the point!
Proof read answers. Ask yourself – Have I written a complete answer? Have I answered the question that was asked?
Match the length of your answer to the space provided.
Watch out for plurals in questions. For example, ‘Name features of graphs’ means that you are required to write at least two features.
Label extra pages clearly and attach them to your exam booklet.
