Rasmus Hansson: The Intricacies of Environmental Politics

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.

Policy-Relevant Ecology: Thoughts from the 4th Conference of the Norwegian Ecological Society

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.

The Motivation Behind Migration

The Crux

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.

Celine Frere: Gender, Representation, and Cultural Shifts in Ecology

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.

Johanna Schmitt: Climate Change and Plant Life

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.

The Shifting of Ecological Baselines

Bushfires like the ones that have ravaged Australia and California this year could become the new norm for the generation that has been born in the last decade, an example of how our perception of ecological change is defined by what has happened in our lifetime

It’s no secret that our world has undergone rapid changes in the last few decades. Extreme weather events are becoming almost the norm and species seem to be going extinct every minute. But as depressing as this may seem, the general doom and gloom we hear about the world on a daily basis still only represents a small percentage of the ills we’ve inflicted on our planet since we’ve been here.

Crossing the River Between Fishers and Fish Science

"We need the next generation of scientists to be at the coalface, communicating good scientific information."

Some fish scientists, like recent ASFB delegate Jarod Lyon, have regular contact with fishers who benefit from the work academics and researchers carry out on fish. But is there enough of this sort of communication between the fish science community and fishers? (Image Credit: Jarod Lyon, CC BY-SA 4.0)

When a food source provides almost half a planet with protein, you can expect the people who deliver that food source to play an important role in society. Fishing is no exception. Any country that has a marine or freshwater ecosystem in close proximity will have a fishing community, and that community can play a variety of roles, from something as simple as putting food on people’s tables to campaigning heavily to keep your country from joining the EU.

So it makes sense that fishers should have access to good fish science, at every level. If you’re a multi-million-dollar corporation, you need to know how fish stocks will respond to certain catch levels over a sustained period. If you’re a local or specialised fishing community, you need to know how available your catch will be in five years given temperature increases. And if you’re one person on a boat in a river, you might want to know how best to treat an over- or under-sized fish to ensure it survives being released.

It follows, then, that there should be open communication between fish scientists and fishers. At this year’s Australian Society of Fish Biology conference, I asked a variety of delegates a simple question: Is there open communication?
