Increased urbanisation may have a negative effect on the richness of moth species like this Vine’s Rustic, but it depends on what scale we consider richness (Image Credit: Patrick Clement, CC BY 2.0, Image Cropped)
Urbanization drives cross-taxon declines in abundance and diversity at multiple spatial scales (2019) Piano et al., Global Change Biology, https://doi.org/10.1111/gcb.14934
You would think that the effect of building a whole lot of stuff on something’s habitat would have a negative effect on just about anything. But building a whole lot of human stuff (maybe let’s retain a modicum of science-ness and call it urbanisation) hasn’t always been shown to be necessarily bad for species. There are a lot of studies out there which show that urbanisation is can be a negative for biodiversity (which makes sense, since for starters it generally breaks up habitat patches and introduces a whole lot more pollutants). But there are also studies showing that urbanisation can increase biodiversity.

In the latest edition of our ongoing look at how ecology has changed over the last half-century, 5 experts talk technology, modelling, and the study of humans. But we also cover some of the pitfalls of recent leaps forward, including the loss of appreciation for species physiology.
You can also check out parts one, two, and our special on fish ecology.

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.
