Nature documentaries and saving nature: Reflections on the new Netflix series Our Planet (2019) Jones, Thomas-Walters, Rust & Verissimo, People and Nature, https://doi.org/10.1002/pan3.10052
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.

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.

Species like the anole exist in natural and urban environments. So how does where they live affect their body shape? (Image Credit: RobinSings, CC BY-SA 4.0, Image Cropped)
Linking locomotor performance to morphological shifts in urban lizards (2018) Winchell, K. et al., Proceedings of the Royal Society of Biological Sciences, 285, http://dx.doi.org/10.1098/rspb.2018.0229
We know that human construction leads to displacement of many species, regardless of the ecosystem. But just because we put up a city, doesn’t mean that all the species that lived there go disappear. Some stay and adapt to their new surroundings. Understanding how certain types of organism respond to new environments is important when considering our impact on a species.
Today’s paper looks at the response of lizards, in this case anoles, to living in the city. The authors wanted to find out, among other things, whether individuals of the selected species showed different locomotive abilities on natural and man-made surfaces based on whether or not they came from the city or the forest, and whether these corresponded to morphological differences.

Rapid warming is associated with population decline among terrestrial birds and mammals globally (2018) Spooner et al., Global Change Biology, DOI: 10.1111/gcb.14361
The term climate change is almost ubiquitous these days. Humans tend to concentrate on how the warming of certain parts of the globe will affect them, but the species we share the globe with also experience a myriad of effects at the hands of climate change. These include rising temperatures constricting the ranges of some species and concurrently extending the range of others, who can move into areas that were previously too cold for them.
Whilst the focus of climate change has often been on species range shifts, the effects on species abundances are less well studied. This paper attempts to quantify the effects of climate change on a large number of bird and mammal species, whilst accounting for other factors which could affect species abundances, like rates of land use by humans, species body size, and whether or not the animals are in a protected area.
