Do whales 'hear' food?


For years, scientists have only been able to hypothesise that large marine creatures such as whales, sharks and dolphins use hearing as a way of locating food.

Now, a research project led by the University of Auckland's Institute of Marine Science will look to confirm what many have long suspected by playing back recordings of prey in the water and tracking how whales respond to them. The world-first study, beginning next year, has the potential to reveal important insights into the relationship between large organisms and their food sources - and whether noise from humans can be a barrier.

Dung beetle plan a risky gamble


Professor Grant Guilford, Dean of Science, criticises the Environmental Protection Agency's decision to introduce dung beetles to aid the breakdown of livestock faeces. In his opinion "the proposal to introduce the insect has been poorly thought out and the impact of such a move underestimated".

Read the full opinion piece by Grant Guilford on the New Zealand Herald website

 

Associate Professor Jacqueline Beggs (School of Biological Sciences) agrees, arguing that "the recent debate about releasing 11 exotic dung beetle species in New Zealand has focused on the disease risk to humans, rather than the impact on native New Zealand ecosystems."

'Hairless ideal' grows on young men


Body hair removal is becoming more common among young men, according to an international online survey conducted by Associate Professor Virginia Braun (School of Psychology) and Dr Gareth Terry (Open University, UK). The survey, which quizzed nearly 600 people aged 18-35 on their body hair grooming habits, found that while body hair was still considered more acceptable on men than it was on women - except on the back or shoulders - male body hair was not seen as particularly desirable.

Studying waves over astronomical distances


Tiny pulses of light one billionth of a second apart, travelling further than from the Earth to Sun, were used in an exquisitely sensitive experiment at The University of Auckland to explore fundamental interactions between light and sound. The research, led by Associate Professor Stéphane Coen (Department of Physics), examined the behaviour of solitons, solitary waves which maintain their shape in contrast, for instance, to waves hitting the shore which break and fragment.

Rangitoto's blasts from the past


cl-rangitoto

Rangitoto may be much older - and more explosive - than previously believed. A new study has led scientists to reassess how volcanoes may behave in the future and could be a large step toward unlocking Auckland's mysterious volcanic past.

Contrary to the long-held belief that Rangitoto was formed less than 700 years ago and has erupted only twice, University of Auckland researchers led by Associate Professor Phil Shane (School of Environment) now suspect there may have been intermittent activity from between 1500 years ago to 500 years ago.

How will Kauri survive climate change?


cl-kauri

How will New Zealand's native giants, the Kauri, survive as our climate gets warmer and drier? This is the topic of a research project by Postdoctoral Research Fellow Dr Cate Macinnis-Ng (School of Environment). Funded by a Marsden Fund Fast-Start grant, Cate and colleagues from Australia and the United Kingdom will investigate the sensitivity of the native conifers, kauri, tanekaha and totara, to water stress. They will compare water-use efficiency in these trees across different rainfall areas and look at how particular trees adapt to a lack of soil moisture.

Scientists have shown that mainland New Zealand has become an increasingly important winter habitat for southern right whales – a population hunted to near extinction in the 19th century – and members of the public have played a critical role in the research. "This endangered whale now seems to be a regular visitor to mainland of New Zealand" said lead author Dr Emma Carroll (School of Biological Sciences). "For the first time we have documented southern right whales returning to the mainland, including females returning with their calves in different years.” The findings suggest that mainland New Zealand could become an important habitat for mothers and calves and perhaps larger social groups.

Traditional treatment of burn injuries often involves years of painful skin grafting, usually from several parts of the person's body. Now there is hope for a different way to treat burn victims. Professor Rod Dunbar (School of Biological Sciences and Maurice Wilkins Centre) and Dr Vaughan Feisst (School of Biological Sciences) are attempting to grow artificial skin, thanks to a grant from the money raised by the Cure Kids’ Red Nose Day appeal. A new technique allows the researchers to grow more than just one layer of skin, which makes it less fragile than conventional artificial skin. "We can now grow skin that is exactly the same in terms of its cellular content as the patient's normal skin which means that it does not get rejected," explains Professor Dunbar.

Call to control feral pigs


cl-wild-pigs
Ground disturbance caused by wild pigs.

University of Auckland research revealing the extent to which feral pigs can disturb forest vegetation and soils has led to a call for the animals to be controlled as a pest in areas of high ecological value. The research led by Dr Cheryl Krull (School of Biological Sciences) as part of her PhD thesis shows that feral pig ground disturbance resulted in a reduction in the diversity of seedlings and saplings in the forest, a dramatic reduction in leaf cover on the forest floor, and altered availability of nitrates (important nutrients for plants) in the soil. Feral pigs might also be responsible for spreading a fungus that is killing Kauri forests.

How to be a good step-parent


Dr Claire Cartwright (School of Psychology) provides an overview of the challenges faced by step-parents and gives advice on how to be a good step-parent, based on her research. She suggests that couples discuss how to introduce the step-parent to the partner's children, and to ensure that the step-parent takes a supportive role based on friendship with the child rather than a discipline role in the first couple of years.

Noisy classrooms leading to voice problems


cl-voice-problems

Thousands of Kiwi teachers are at risk of developing serious voice problems because of high noise levels and poor acoustics in classrooms. Two studies, led by University of Auckland speech expert Professor Suzanne Purdy (School of Psychology) and PhD student Sylvia Leao, have revealed more than a third of teachers have suffered problems with their voices at some point.

Pakeha label ka pai for most


cl-pakeha

Being called a Pakeha is not an insult, reveals a survey of thousands of people on attitudes and values, conducted by Dr Chris Sibley (School of Psychology) and Dr Carla Houkamau (Business School). The findings bust a recurrent myth that Pakeha is offered in a derogatory fashion. "We found no evidence whatsoever for the suggestion that the term Pakeha is in any way pejorative or might reflect a negative attitude toward New Zealanders of European descent," says Chris Sibley.

Magnetism and Bird Navigation


cl-animal-migration

Animals perform great feats of migration. But how do they navigate so accurately without the aid of the maps and GPSs that we humans rely on? It’s a question that has long intrigued Michael Walker (Biological Sciences) and over the last few years he has gathered increasing evidence that animals are able to follow the earth’s lines of magnetism, using their own in-built magnetic detectors.

More recently applied mathematician Claire Postlethwaite (Department of Mathematics) has also been pondering the mysteries of animal navigation, and has developed a simple geometric model of navigation, based on a logical pattern of errors that Michael detected in both his own homing pigeon data and in other researchers’ data.

New Year brings (potentially) good news for conservation of species on Earth


cl-conservation-photo-brady-doak

Most species will go extinct before they are ever discovered — or so some researchers believe. But the situation may not be so hopeless after all, according to a paper published in Science by Associate Professor Mark Costello (Institute of Marine Science) in cooperation with researchers from Griffith University and the University of Oxford. The scientists show that the claims are based on two key misconceptions: an over-estimation of how many species may exist on Earth, and the erroneous belief that the number of taxonomists (people who describe and identify species) is declining.

Maths, Queuing and Heart Patients


cl-auckland-city-hospital

When Auckland City Hospital was experiencing a cancellation rate for cardiac surgery that was approaching 30% the staff decided to ask a mathematician for help. Statistician Associate Professor Ilze Ziedins (Department of Statistics), an expert in queuing theory and probability, and two of her graduate students, William Chen and Kim Frew, set out to develop a mathematical model of the Cardiavascular Intensive Care Unit using R, a statistical environment and programming language initially developed at the University of Auckland. The model took real-life data, and investigated different staffing and resourcing scenarios, and as a result was able to decrease waiting times for cardiac surgery.

The secret to happiness is money


cl-money

While people cling to the adage that "money can't buy happiness", research suggests the opposite is true, and the more money you have, the happier you'll be. "It's an axiom that money can't buy love. Our results, however, show that, to a certain extent, it can buy happiness and good health," said the report by PhD student Nikhil Sengupta (School of Psychology) published last year in the New Zealand Journal of Psychology.

Dr Craig Millar (School of Biological Sciences) uses ancient penguin DNA from Antarctica to uncover the past and make predictions for the future. Using genome sequencing data the research team examines what evolutionary changes had occurred in Adelie penguins since the peak of the last glacial period, between 18,000 and 25,000 years ago. Antarctica had warmed about 10 to 12 degrees Celsius since deglaciation started about 12,000 years ago, and the team wanted to discover what, if any, evolutionary response that had prompted.

Brainy crows


cl-crows

The School of Psychology's research on New Caledonian crows' cognition and culture has been widely reported nationally and internationally in the past years. By studying the social structure and behaviour of the crows and the details of their difficult daily lives, the researchers hope to gain new insights into the evolution of intelligence, the interplay between physical and social skillfulness, and the relative importance of each selective force in promoting the need for a big animal brain.

Recent research, led by Dr Alex Taylor, suggests that New Caledonian crows can make inferences about the behaviour of hidden animals in their environment, an ability previously observed only in humans. The study was published in the Proceedings of the National Academy of Sciences and received international media attention.

At least one third of the species living in our oceans, and perhaps up to two thirds, are unknown to science according to the work of an international research group, including Associate Professor Mark Costello (Institute of Marine Science) who co-led the research with Ward Appeltans of Flanders Marine Institute and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. The researchers calculate that there are less than 1 million marine species, far fewer than some previous estimates. Around 226,000 species have been described by science and as many as 72,000 more are in collections awaiting description.

Evolutionary benefits of sex in difficult places


Dr Mat Goddard and PhD student Jeremy Gray (Biological Sciences) have provided the first experimental explanation of how sexual reproduction helps species adapt in challenging real-world environments, solving a classic conundrum in evolutionary biology. The scientists used yeast that could be switched from asexual to sexual forms to show that yeast populations became best adapted to their environment if they reproduced sexually and underwent complete gene mixing.
