Towards Gender Equity in Ecology: Part Two
Professors Amy Austin, Eva Plaganyi, Anne Sverdrup-Thygeson, Prue Addison and Johanna Schmitt (not pictured) share their views on gender equity in ecology (Image Credit from left: Amy Austin, CSIRO, NMBU, Synchronicity Earth; All images cropped, CC BY-SA 2.0)
In Part Two of our ongoing look at gender equity in ecology, four prominent female ecologists share their thoughts on how gender equity in ecology has progressed, and where it needs to go from here.

Behavioral Ecology for the Masses

Previously on this site I’ve summarised an article I wrote linking some concepts from behavioral ecology with evolutionary biology. Now I’m back to say a bit more about what behavioral ecology actually is. Being introduced to the field of behavioral ecology was what sparked me to actually consider a career in science. It’s a fascinating and beautiful field, and I hope I can show you why!
Are Animals Doing the Wrong Thing?

The Crux
Why do animals behave the way they do? Behavioral ecology is a field of research trying to explain the ecological rationale of animal decision making. But quite often, it turns out the animals are doing the ‘wrong’ thing. Why don’t all animals make the same choice, when there clearly is a best option? Why do animals consistently do too little or too much of something?
The Changing Face of Ecology: Part 3

In the latest edition of our ongoing look at how ecology has changed over the last half-century, 5 experts talk technology, modelling, and the study of humans. But we also cover some of the pitfalls of recent leaps forward, including the loss of appreciation for species physiology.
You can also check out parts one, two, and our special on fish ecology.
Episode 8: The Gremlins/Mogwai

We kick down the kitchen door and go to bloody war with the Mogwai, from 1984’s Christmas classic Gremlins. Dave gives China tips for invasion, Sam says the word ‘tarsier’ too much and Adam can’t resist showing off how much Mandarin he doesn’t know.

18:02 – Movie Any Good?
21:40 – Physiology of a Mogwai

Victory May Not Guarantee Survival in Species Conflicts
Spreading of the Australian yabby has led to decreases in other local species. But what happens when these species meet? (Image Credit: Daiju Azuma, CC BY-SA 2.5, Image Cropped)
Insight into invasion: Interactions between a critically endangered and invasive cray fish (2018) Lopez et al., Austral Ecology, doi:10.1111/aec.12654
The Crux
When we talk about invasive species, often the first thing that pops into our minds are things like feral cats, wild pigs, vicious newcomers that wipe out species or transform vast areas. But often what we focus on less are species which arrive and simply outcompete the locals.
The yabby (Cherax destructor) is one such invader. An Australian species, it has been introduced to new waterways through the country and is now threatening other species, including the Falls Spiny Crayfish (Euastacus dharawalus) in eastern New South Wales, Australia. The introduction of the yabby has resulted in a decreasing habitat range for the crayfish, but what sort of mechanisms are causing this? This experiment aimed to document interactions between the two species.
