There has been a lot of recent (and well deserved) press surrounding the bush fires in Australia. Because of these fires countless animal and plant life has been lost, and the most visible example of that are the koalas. You probably saw the video of a woman running into a burning area to save a koala from the fire*. Unfortunately, most of the koalas didn’t have people around to save them and over 1,000 are estimated to have died. Because of this a group has claimed that koalas are now “functionally extinct”, and the press has run with this claim. While it is unfortunate that this misinformation spread so quickly and so widely, the good news is that koalas are in fact NOT functionally extinct. Great! But what does being “functionally extinct” mean?
City life alters the gut microbiome and stable isotope profiling of the eastern water dragon (Intellagama lesueuriii) (2019) Littleford-Colquhoun, Weyrich, Kent & Frere, Molecular Ecology, https://doi.org/10.1111/mec.15240
It’s a pretty fair call to assume that if you build a city on a species’ habitat, it might be a little miffed. Yet as human settlements expand worldwide, many species are showing that they’re able to make rapid changes to their biology to adapt to living around humans.
This includes their diet, of course. As diets shift, many other aspects of a species’ biology follows, including the microbes that live in a species’ gut. And gut microbes influence a huge range of factors, including immunology, development, and general health. The response of a gut microbe community (the gut microbiome) to a new diet can in turn affect an animal’s ability to adapt to that environment.
Charismatic species like the bottlenose dolphin are generally easier to find funding for. So what’s it like to work with them as a scientist. I spoke to evolutionary biologist Celine Frere to find out (Image Credit: Jason Pratt, CC BY 2.0, Image Cropped)
We’ve talked at length about charismatic species on Ecology for the Masses. They’re the ones that draw in the public, whether they’re cute and fluffy, majestic, or dangerous. They’re generally easier to procure funding for. So what’s it like to work with them?
During a recent visit to the University of the Sunshine Coast, I sat down with Doctor Celine Frere to find out. Celine works with two of Australia’s most charismatic species, the koala and the bottlenose dolphin. We talked about the pros and cons of charismatic species, getting the public interested in them, and the future of global conservation.
Australia plays host to a wonderful range of very endearing species. Tourists come from the world over to get up close with kangaroos or koalas. But the charisma of these animals can often lead to issues, whether it’s prioritisation of resources for them over other more endangered species, or even to the detriment of the species themselves.
Doctor Kath Handasyde of Melbourne University has been working with Australian field wildlife for almost 40 years, and is perhaps the most charismatic teacher I had during my Bachelor’s at the same institute. During my time in Melbourne, I had the chance to talk to Kath about the sometimes problematic role of charismatic species in Australian wildlife conservation.
