Tourist boats looking for dolphins on the Mekong River, Cambodia. Gerry Ryan

It’s hot, and you’re sitting sweating in a small wooden boat. Your cold bottle of water is dripping, and the pink polyester roof does nothing to shade the glare of the setting sun. The young man at the back of the boat smiles and points at the water, and there you see it: one of Cambodia’s most magnificent spectacles.
Angkor Wat? No, it’s a critically endangered dolphin rising from the brown waters of the Mekong River, breathing, looking at you, and then disappearing below.
Our recent research suggests that while dolphin and whale tourism in Southeast Asia can be great for communities, it can also come at a cost to the environment.
So what should you look for if you’re going on tour? Continue reading
QAECO researchers Luke Kelly and Mick McCarthy, alongside Kate Giljohann and a number of other collaborators, have recently started up a new fire ecology project! Read more about it below:
Now that we’ve assembled our exciting team – including new recruits Dr Kate Giljohann (Research Fellow), Fred Rainsford (PhD student) and Kate Senior (PhD student) – it’s a perfect time to introduce the project.
The Team: Luke Kelly (UoM), Andrew Bennett (La Trobe/ARI), Andrew Blackett (DELWP), Michael Clarke (La Trobe), Kate Giljohann (UoM/La Trobe), Michael McCarthy (UoM), Fred Rainsford (La Trobe), Kate Senior (UoM).
What are we going to do?
This year’s Ecological Society of Australia conference is upon us! Next week will see the annual migration of a flock of qaecologists over to the conference, held this year in Fremantle, WA. There will be presentations & posters on topics ranging from feral predator management, to the impacts of global trade on biodiversity, to validating distribution models, to using drones to find sneaky tree kangaroos!
In addition, Jane Elith will be giving the Keynote address on Tuesday morning, where she will be presented with the Australian Ecology Research Award for 2016. Jane will be giving a talk about the application, challenges and recent progress in using species distribution models with kinds of data that are typically available.
So if you’re heading to ESA, keep an eye out for the following talks & posters from qaeco members throughout the week: Continue reading
Climate change is predicted to be one of the major threats to the biodiversity loss in the coming century, both via direct impacts on species and through synergistic effects of other extinction drivers. For last week’s reading group, master’s student Anwar Hossain, selected a paper titled “Assessing species vulnerability to climate change”, published in the journal Nature Climate Change. The paper, led by Michela Pacifici and his colleagues of the IUCN Climate Change Specialist Group, examined the focus of existing studies on species’ vulnerability to climate change, and discussed the limitations /benefits of three main approaches used to conduct such assessments (i.e., correlative, mechanistic and trait-based approaches).

The latest round of ARC funding has been announced and we would like to congratulate those qaeco members who were successful in their applications:
Brendan Wintle & Pia Lentini received funding on their Discovery Project predicting the ecological and economic impacts of trade. They will be working alongside their CEBRA colleagues Mark Burgman & Tom Kompas, CSIRO scientist Dr. Brett Bryan, & Professor Joshua Lawler at the University of Washington, as well as a number of postdocs & PhD students. This project “aims to understand and predict the effects of global trade on land use and biodiversity. Growth in international trade increases trade-mediated land-use by increasing demand for commodities directly or indirectly derived from the land. Accurate predictions of trade effects and opportunities would allow governments to maximise ecological and economic benefits and minimise effects through judicious planning and regulation, but such analyses do not exist. This project expects to advance trade policy evaluation by improving and integrating computable global equilibrium models and land-use and ecological models to better characterise consequences of trade.”
Reid Tingley was awarded a DECRA (Discovery Early Career Researcher Award) to conduct research into incorporating developmental plasticity into models of species distributions. His project “aims to develop a generalizable framework for predicting effects of environmental variability on organisms’ developmental strategies, using anuran tadpoles as a test case. This framework will reveal how environmental variability influences geographic variation in developmental strategies, and provide tools to account for that variation in mechanistic models of species distributions. These tools are expected to increase the capacity to predict extinction risk in changing environments, and be amenable to any taxon or environment, providing a solid foundation for understanding the evolution of life-history strategies in variable environments.”
Well done! And those that missed out this time – you’ll get ’em next round!
For this fortnight’s reading group we got together to discuss a recent paper in Conservation Letters by environmental ethicist, Michael Paul Nelson, and colleagues.
Cecil the lion lemon shortbreads. Because themed baked goods are always a welcome reading group snack, regardless of your opinions on the morality of consequentialism.
Emotions and the Ethics of Consequence in Conservation Decisions: Lessons from Cecil the Lion uses the controversy surrounding last year’s killing of a well-known lion in Zimbabwe to frame ways conservationists should think about the ethics of trophy hunting. Natasha Cadenhead picked the paper because a slew of academic articles have recently been published on the killing of Cecil (here, here, and here, for example) and because it covers an area that our group rarely works on, both research-wise and geographically.
Trophy hunting – the practice of hunting animals for recreation, rather than for sustenance, income or protection – is harnessed as a tool for conservation in some countries. It is an issue that causes heated debates in both the public sphere and within conservation circles. Below are some of the common arguments that we discussed both for and against using trophy hunting as a means of conservation:

In our latest QAECO reading group, Kate Giljohann selected an editorial published in the Journal of Applied Ecology titled “Management by proxy? The use of indices in applied ecology”. The article, led by Philip Stephens and editors of the journal, discussed the role of proxies in applied ecology and ways to improve their use in environmental management.
Most of us use proxies or indices in our research. But what are they? Well, scientists and managers often want to measure and keep track of key attributes of ecological systems to inform decision-making. For example, estimating population size and the rate at which it is changing is fundamental for determining the status of species, whether they should be managed, or how they have responded to management intervention. But, often these quantities can be difficult or time consuming to measure directly, so instead we measure something else that’s closely related. The assumption is that if we keep track of what our proxy is doing, we can also keep track of what our real quantity of interest is doing as well.
