Disgusting Animals: what underlies the ‘Eeeww’ factor?

Do slugs disgust you?

How about dog poo, or road kill?

Tyler (T.J.) Kasperbauer gained his PhD in Philosophy from Texas A&M University where he wrote a dissertation on moral psychology and animal ethics.

He is currently completing post-doctoral research at the University of Copenhagen, working with the well-known Peter Sandøe.

T.J.’s main areas of research are applied animal and environmental ethics, moral psychology, and philosophy of psychology.

In this episode, we explore his interesting research into the area of disgusting animals and their traits, why they disgust us, why they should, and what it means for people’s relationships with them.

An evolutionary experiment: when did wolves become dogs and what comes next?

When did wolves become dogs?

What evolutionary and developmental processes are involved in creating physical variation?

Is selection responsible for moulding the diversity of life?

Or does developmental bias via drive and constraint determine how animal shapes change?

Abby Drake is interested in the processes that produce macroevolution and dictate which physical appearances, evolve and which do not.

She is especially interested in learning how species evolve: What mechanisms produce enough physical or behavioural change to ensure reproductive isolation on the population level?

To this end, she studies developmental processes that lead to large modifications of morphology, using variation in vertebrate skulls to answer these questions.

Abby uses three-dimensional scan data to capture each specimen’s 3D geometry.

This type of data allows her team to look at the shape of the skull holistically using a sophisticated shape analysis called geometric morphometrics.

While she also works on cetaceans, owls and primates, this episode focuses on her extensive work examining canids: when did wolves become dogs, how have we shaped them, and where might they go in the future?

Do fish feel pain? Diving in to the deep end of fish welfare

Do fish really feel pain?

You might assume yes, but you’d be wrong.

Kind of.

You see – it’s complicated.

Dr. Ben Diggles has worked with government, aquaculture industry, recreational fisheries, and commercial fisheries throughout New Zealand, Australia, Asia and the Pacific Islands.

Ben’s core work includes import risk analysis, fish and shellfish health, fish welfare, development of feeding attractants for aquaculture, and development of medicated feeds for aquacultured finfish.

In his spare time Ben studies the effects of declining water quality on our estuaries, and is active in his local community developing solutions to these problems, like Oyster Reef Restoration.

In this episode, we catch up on the latest scientific findings relating to fish pain and learn more about the Ikijime  method for killing fish captured for eating.

So let’s find out if fish feel pain.

Just walking the dog: what promotes healthy humans?

Did you know scientists are studying the ways that you walk your dog?

What motivates you, how long you exercise for, what features (like footpaths and dog parks) promote human activity – all these questions and more, are being studied by researchers, Hayley Christian and Carri Westgarth.

Hayley’s background in human health teamed with Carri’s expertise in canine behaviour and welfare have created a research team exploring the human, dog and environmental factors that best promote active and healthy communities.

Is your dog optimistic? Cognitive bias in animals

Does your pet have a glass half full, or glass half empty take on life?

It’s a recent discovery that many animals can be optimistic or pessimistic based on their experiences.

Dr. Melissa Starling holds a Bachelor of Science in Zoology and recently gained her PhD from the Faculty of Veterinary Science at the University of Sydney with a topic that covered elements of dog behaviour, personality, emotions and cognition.

She has long had a passion for animal behaviour and animal training that has intensified as she learns more.

In this episode, we talk to Mel about her PhD research investigating optimism and pessimism – or cognitive bias – in dogs.

Emotions, memory and social networks – of Goats

“Do goats have emotions?” is something rarely searched for on Google, but if you think about it, it’s a very good question.

The answer is yes, goats do have emotions.

Believe it or not, they also have social networks, puzzle solving skills, and impressive long term memories?

We’re not even kidding! Alan McElligott is based at the School of Biological and Chemical Sciences at the Queen Mary University of London, where he and his team research cattle, fallow deer, and goats.

In this episode, we talk about their recent work, and how it contributes to improved understanding of animal behaviour and behavioural ecology, raising important considerations for animal husbandry and welfare of goats in companion animal, livestock and pest contexts.

It’s time to learn about the emotions of goats!

A Game of Drones: Using Drones in Conservation

When someone turns a fun hobby into a game changing tool for good, it’s inspirational!

That’s exactly what Lian Pin Koh has achieved in bringing affordable drone technology to aid conservation scientists.

A tropical ecologist by training, Associate Professor Lian Pin Koh received his PhD from Princeton University, where he studied the environmental and policy implications of oil-palm development in Southeast Asia.

He then spent several years researching key scientific and policy issues concerning tropical deforestation and its impacts on carbon emissions and biodiversity while based in Zurich.

Lian Pin currently leads the Applied Ecology & Conservation group at The University of Adelaide in South Australia, where they ultimately seek to do good for society.

In this episode, we speak with Lian Pin and learn about his exciting work using drones in conservation.

Gestures & communication: chimpanzees have a point

Imagine deciphering the first form of intentional communication to be recorded in the animal kingdom, such as how chimpanzees communicate.

That’s exactly what Dr. Catherine Hobaiter has done after years of following wild chimpanzees in the Budongo Forest of Uganda, Africa.

She studies the evolution, acquisition and flexibility of communication and social behaviour, in particular through long-term field studies of wild chimpanzees.

For the past seven years, Cat has been working as a primatologist at a forest research-station in Uganda to better understand chimpanzee communication and behavior.

She hopes to to advance our understanding of great ape communication, and in addition, by looking at areas of overlap or species specific traits, she hopes to also gain an understanding of the evolutionary origins of language.

In this episode, we learn from Cat about her exciting observations of a communication system where animals don’t just share information through behaviour, but deliberately send messages of meaning to each other.

Listen in, and you’ll find out exactly how how chimpanzees communicate.

Horse racing’s big hit: why use whips on horses?

Why are whips used in horse racing?

Do whips make horses run faster or win races?

Are jockeys using whips to steer and stay safe, or are they simply whipping tired horses?

These are questions that prompted Professor Paul McGreevy of the University of Sydney to research the use of whips in horse racing.

Paul is recognised by the Royal College of Veterinary Surgeons as a specialist in Veterinary Behavioural Medicine.

His research focuses on the behaviour and welfare of horses and dogs, and he is the author of six books and over 120 peer-reviewed articles on animal behaviour.

Paul’s award-winning research examining the use of whips in horse racing aims to further our awareness of the experience of horses, extending to a recent experiment capturing the thermographic effects of his own leg being hit with a padded whip.

As the Spring horse racing carnival hits its peak in Melbourne, Australia this week, we asked Paul to discuss his findings and what it means for horses, beyond the glamour and excitement of race day.
