Whilst cichlid fish might look incredibly diverse, they are actually all relatively genetically similar. So how do we define genetic diversity, and how do we conserve it? (Image Credit: Emir Kaan Okutan, Pexels Licence, Image Cropped)

Making Brexit work for environment and livelihoods: Delivering a stakeholder informed vision for agriculture and fisheries (2019) Beukers-Stewart et al., People and Nature, https://doi.org/10.1002/pan3.10054
Ok, last article on Brexit for the time being. Everyone rest easy. This week’s paper looks once again at the consequences of Brexit for both the agricultural and fishing industries, and the knock-on effects on Britain’s farmland and marine ecosystems. As has been echoed both by this week’s earlier interview with Abigail McQuatters-Gollop and the views from this week’s British Ecological Society Annual Meeting, Brexit can represent an opportunity. An opportunity to put together a directive that helps maintain both marine and terrestrial ecosystems whilst not putting the people at a disadvantage.
This week’s paper is trying to get an understanding of how to put together that framework, by speaking to the people Brexit will likely impact more quickly than others: farmers and fishers. Government subsidies support many British farmers, and it’s not clear whether they’ll remain in place going forwards. Quotas could shift dramatically for fishers.
The concept of ecotourism has seen a massive surge in popularity over the last decade. It is defined by The International Ecotourism Society as “responsible travel to natural areas that conserves the environment, sustains the well-being of the local people, and involves interpretation and education.” In other words, when you’re participating in ecotourism, you should be enjoying some sort of ecological marvel, and learning something, ideally whilst not damaging local people or ecosystems. Yet this can be a lot more complicated than it sounds.
Nature documentaries have long been the starting point for many an ecologist. They’re the reason that David Attenborough has long been so idolised among lovers of nature. But whether or not they actually work as a conservation tool has always been a little more difficult to say. Additionally, while they’ve long showed the wonder of animals, plants, insects and everything in between, many have shied away from the damage that humans have inflicted on the planet. This week’s authors wanted to examine Netflix’s latest move into nature documentaries, Our Planet, and see if it delivered on their promise to showcase the anthropogenic dangers that ecosystems face today.
To act to prevent a species going extinct, we have to know that it’s at risk of extinction. Ecologists and conservationists simply don’t have the time or resources to make sure that all species remain safe. So having reliable methods of predicting species extinction risk is crucial.
On a global scale, the relationship between a species size and the area that it is found in (geographical range) has been studied intensively since ecology’s inception, both in existing and prehistoric species. Initial research showed that in general, the larger a species is, the larger its range size needed to be, with large species that had relatively smaller range sizes more prone to extinction. However more recent work has shown (naturally) that there are exceptions to this, with mammals viable range size actually decreasing up to a certain ‘breakpoint’, after which the size grows again.

Running EcoMass means we get to sit down with some exceptionally interesting ecologists, conservations, and in this post, even environmental politicians. Most of these individuals have been a part of the discipline for much longer than we have, so when we get the chance we pick their brains about how ecology has changed over the past decades. It’s always interesting to hear which aspects of ecological life we take for granted simply weren’t there 40, 30 or even 10 years ago.
Whilst it might seem like little guys like this don’t have much to smile about these days, being optimistic about the state of the environment is more important than ever, according to Nancy Knowlton (Image Credit: Rosalyn Davis, CC BY-NC-SA 2.0, Image Cropped)
