The farming industry has had a strange relationship with ecology over the years. They have been maligned by claims they shoot native species, suck up water greedily from nature and the people, and pollute our countryside with pesticides, all whilst producing the food many of us subsist on. So why haven’t ecologists worked with them more closely?
At the recent NØF 2019 Conference, Tanja Petersen and I sat down with Canadian ecologist Professor Andrew MacDougall, who has been working with the farming industry for the past six years to quantify their contribution to ecosystem services. We talked about the often damaging public perception of farmers, how his stereotypes were challenged by working with them, and the biggest problems the industry will face heading into the next fifty years.

I’ve been on a bit of a policy trip lately. The latest Norwegian Ecological Society conference was heavily policy based, so much so that it inspired me to get in touch and set up a meeting with local freshwater managers in a country in which I do not speak the local language. So when the CBD hosted a one-day seminar on the Intergovernmental Science-Policy Platform for Biodiversity and Ecosystem Services (mercifully usually referred to only as IPBES) rolled into town, I was right on board.
Eating beef isn’t great for the environment. But can someone who occasionally snacks on cows still be in favour of conservation and other ecological causes?
Today I want to talk about a tweet. Or more accurately, the attitude to sustainability that this tweet represents. It occurred during the recent Ecological Society of Australia conference, and went roughly thus*.
Good to see only vegetarian food at ESA2018. We know that it’s not possible to be truly in support of conservation unless you cut meat out of your diet.
Now for starters, I want to make it clear that I am 100% in support of eating vegetarian. For those of us fortunate enough to be living in relative affluence, vegetarian diets are easy to maintain, generally cheaper (based on personal experience), and have a proven positive impact on the climate. I’m not completely vegetarian, but I take a lot of steps to minimise my diet’s climate footprint. It doesn’t take much.
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)
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.
Sea otters are one of many charismatic species found along the California coast, yet recovery doesn’t seem to be helping them. Is it something about their habitat that is preventing population growth? (Image Credit: “Mike” Michael L. Baird, CC BY 2.0)
Gaps in kelp cover may threaten the recovery of California sea otters (2018) Nicholson et al., Ecography, DOI:10.1111/ecog.03561
In the 18th and 19th centuries, the fur trade was a massive industry in North America. As a result, many species were hunted and trapped to near extinction. The California sea otter (Enhydra lutris) was reduced in population to less than 50 total individuals. The enactment of the Internation Fur Treaty allowed the species (and others) to come back from the brink of extinction, and they now number over 3200 individuals and are spread across 525km of the California coast. Interestingly, although the population is recovering, it has not bounced back as quickly as other protected mammals living in the same habitat. The California sea lion, for example, has a maximum population growth rate more than twice that of the sea otter (11.7% compared to 5%).
Despite the remarkable recovery of the species, the sea otters occupy less than a quarter of their historic range and have not expanded along the coast in 20 years. The authors of this paper wanted to investigate what it is about the sea otters and their habitat that is slowing this population’s growth rate and spread along the coast.
Fishing is an important part of Australian society. So is communication between fish scientists and fishers strong enough? (Image Credit: State Library of Queensland, CC0)
Last Thursday, I posted an article on the need for more contact communication the fish scientist community and the fishing community, which you can find here. It gives a breakdown of why better communication between the two groups is mutually beneficial, and how it could be improved. The piece was written after talks with a number of prominent Australian fish biologists, whose thoughts I’ve shared in more detail below.
I speak to another group of influential researchers on how ecology has changed over the recent decades (Image Credits: Jarod Lyon, Gretta Pecl, CSIRO, CC BY-SA 2.0)
I’m 29. It’s not like that makes me uniquely qualified to give me the youth’s perspective on ecology today. But it does make me 100% unqualified to talk about how ecology has changed in recent decades. So when I was at the recent Australian Society for Fish Biology Conference (a line you’ll surely be sick of if you’ve been keeping up with my recent interviews), I decided to get some uniquely fishy perspectives on how our discipline has changed over the last 20-30 years.
The following commentaries are naturally from fish biologists. If you’d like a broader perspective on the changing face of ecology, check out Part One and Part Two of this series. You can also find the full interview with all the scientists below by clicking on their names.
