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 (Image Credit: dm4244, CC BY-SA 4.0)

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?
Climate change is something that we hear about on a daily basis. The dire warnings tend to concern sea levels rising and temperatures varying so much that we have more intense and deadly storms than before, but these are all direct effects of the climate. Another thing that climate change can do is have indirect effects on organisms.
Organisms with complex life cycles spend the juvenile part of their lives in one environment before moving on to the adult stage in another environment. The researchers in this study wanted to know how simulated climate change during the juvenile stage of the organisms lifetime could affect the adult stage.
California is ablaze, again. So why is this part of the world so notorious for catching fire? (Image Credit: Daria Devyatkina, CC BY 2.0)
Recently, I was looking for skiable snow in central Norway when I bumped into a chatty Norwegian man. When I told him I was Californian, he asked why my state was always on fire. The story demanded vocabulary beyond my grasp of the language, so this story is for your benefit, my random friendly Norwegian. This is a story of resource mismanagement, of urbanization, Pocahontas, and a policy that was a bear’s favor.
As a fish ecologist living in Norway, it’s a joy to be able to travel to Melbourne and interact with the people that are driving forward fish science in my home country. So when I found out that the Australian Society of Fish Biology’s annual conference was taking place 3 days after my first flight home since 2016, I knew it was an opportunity I couldn’t pass up.
We’re on the last day of the conference at the moment, and over the next 2 months I’m looking forward to bringing you a number of insights, including interviews with guest speakers Eva Plaganyi and Gretta Pecl and pioneers of intriguing projects like Peter Unmack and Jarod Lyon. I’ll also have a fish edition of The Changing Face of Ecology, and some articles on how the angling community and the fish science community interact in a country with one of the most unique fish assemblages in the world.
Two weeks ago, I published Part One of our look into how ecology has changed over recent decades. My colleague Kate Layton-Matthews and I have put this question to a number of ecological researchers from all over the world. Here are some more responses on how our field has evolved, from the publishing of papers to land clearance to the job market.
The image of the lone polar bear has become almost ubiquitous in step with growing awareness of climate change. So why hasn’t the scientific community been able to convince the world to act accordingly? (Image Credit: Pixabay, CC0)
