The concept of interdisciplinarity (essentially, scientists from different backgrounds working together to solve scientific questions) has played a major role in the development of ecology, and science in general, in the last few decades. As odd as it sounds, working across disciplines, even those as closely related as population and behavioural ecology, wasn’t a regular occurrence. Papers with one author were fairly commonplace.

Environmental politics is a tricky business. We live in a world where environmental crises are at the forefront of the news cycle, and in which science is simultaneously becoming the subject of distrust. So it makes sense that at this point, politics should be adapting and evolving as science does.
So when Rasmus Hansson stopped by NTNU last month, Sam Perrin and I took the chance to sit down with him and see whether this was the case. Rasmus studied polar bears at NTNU in the 70s, before later becoming the leader of the World Wildlife Fund in Norway and then of the Norwegian Green party. We spoke with Rasmus about the transition from conservation to politics, the clash of ideologies and the future of environmental politics.

I spent last week up in Tromsø, Norway, for the 4th Conference of the Norwegian Ecological Society. A two-hour flight further north might not seem like a big deal, however if I were a species alone to myself, my northern distribution limit based on temperature would be Trondheim, where I currently reside. It’s just too damn cold for an Australian in the Arctic Circle! Yet Tromso was surprisingly mild last week, coming off the back of a particularly warm winter. And whilst that might sound great, warming temperatures in the Arctic may cause a plethora of negative effects on local wildlife, including starving local reindeer populations and reducing the vital mosquito population.
Species like this red-crowned crane perform yearly migrations, but how do they weigh up the costs and benefits? (Image Credit: Alistair Rae, CC BY-SA 2.0)
Where the wild birds go: explaining the differences in migratory destinations across terrestrial bird species (2018) Somveille, Manica & Rodrigues. Ecography, 42, p. 225-236.
Migratory birds make up a huge chunk of the world’s bird life, yet there are still a lot of gaps in our knowledge concerning why they migrate to the areas they do. There’s a variety of potential benefits to migration, from remaining within a comfortable temperature range or a preferred habitat, to gaining access to areas that have a surplus in resources, to escaping competition with resident species. However, migration also results in increased mortality due to the amount of energy it takes. This week’s study tried to analyse the drivers of migration, and what trade-offs were made between migration’s potential benefits and costs.
The lack of senior female researchers can be daunting to younger female scientists, but openness and honesty combined with a willingness to strive for higher positions can bring about a cultural shift in ecology, says Dr. Celine Frere.
During my recent trip to the Sunshine Coast in Australia, I sat down with Dr. Celine Frere and talked about her work with charismatic species, which you can read about here. However, Celine is also one of Australia’s Superstars of STEM (Science, Technology, Engineering and Math), an initiative of Science & Technology Australia designed to raise the profile of female scientists in Australia. With this in mind, I had a chat with Celine about gender equality in ecology, and the advice she’d give to young female researchers.
We sometimes ignore the effects of climate change on plant life, but the potential severity of these effects isn’t something that should be ignored for long (Image Credit: Pisauakan, CC0)
From the California wildfires to the recent strikes across Australian primary schools, climate change is a topic that only seems to grow in its ubiquity. Yet whilst humans are increasingly focused on more obvious repercussions, such as extreme weather events, animal extinctions and shifting coastlines, we sometimes forget that climate change will have severe repercussions for plant life as well.
I spoke to Professor Johanna Schmitt of the University of California earlier this year to discuss some of those repercussions. Johanna’s team is working to determine how well certain plant species will be able to adapt in the face of rapid climate change.
