Hello all!
I'm Cass. I'm an ecologist who focuses on animal health and behaviour. This includes studying monkeys and hedgehogs. But I also dabble in other conservation research, accessibility in STEM, and fieldwork pedagogy.
And I have two pet rabbits

Ecstatic, during cooling (11°C) swim, after @rspb.bsky.social Volunteer Monitoring of Farm Wildlife at a Legge Farm in Norfolk Fens, to meet my 1st ever European/Common Carp (Cyprinus carpio), complete with barbels at the mouth. Big beauties. bsky.app/profile/nume... #MySwim #carp #commoncarp 1/6

Always a privilege to be teaching out at Mpala Research Centre
Our MSc Biodiversity and Conservation students are having a great time so far

Ah ha! I think I might have cracked it 🤞
I'm currently trying to crop utilisation distributions by habitat type (without recalculating the UD). I've done it before, but I can't seem to replicate it well enough for me to make the conversion back to an estUDm for the UDOI calculations

PhD opportunity with me (RSPB) at Sheffield Hallam combining ecology (building-nesting birds esp. Swift) + building design & planning (Net Zero goals & retrofit). We need a strong student interested in both! Is that you? url.uk.m.mimecastprotect.com/s/cNyjCR636C... Please repost.

There are concerns that Bluesky's impact has faded since the initial hype. This is false.

That impression results from reading headlines about social media instead of the hard data.

The five HIGHEST points of Bluesky posts mentioning research all occur in the last 2 weeks.

Really useful tip highlighting the flexibility of map visualisations in R and use of the excellent Patchwork package.

How to use a histogram as a legend in {ggplot2} | Andrew Heiss
Land isn’t unemployed—people are. Here’s how to use R, {ggplot2}, {sf}, and {patchwork} to create a histogram legend in a choropleth map to better see the distribution of values.

I’m very struck by the fact that kids who grow up in the TFL zone have basically free and highly efficient transport over a huge area whereas in other parts of the country our kids have to pay a lot of money for infrequent and unreliable transport. The impact that has on your horizons must be huge.

Are big bad badgers driving hedgehog declines in Britain? Hot off the press.. short answer is no says @richardyarnell.bsky.social. Very weak -ve relationship between the species but absolutely dwarfed by other factors, esp. road casualties. Read whole paper here: doi.org/10.1002/ece3... #hedgehogs 🦔

Several years ago I worked with Terry Maple to quantify usable space in zoo exhibits, but we were limited by what was technologically possible for us at the time. I'm very excited to see this new paper successfully using 3D photogrammetry to build the models more efficiently

Using 3D Photogrammetry to Quantify Usable Space in Zoo‐Housed Primate Habitats
Studies of zoo animal space use typically use ground-level measurements as a proxy for “usable space,” but this method ignores above ground areas that are behaviorally relevant to arboreal species. P...

Hey #RStats here are some great new terms to add an R to to make a package name if you want to fuck with US science.
Just received an email saying that it's not advisable to include the following words in future applications for research funding to the US DOT. Here we are.

Bird nests made from anti-bird spikes?! 🤯

Hi, I'm a nest researcher 👋 and new here on BlueSky, sharing the craziest #bird nests I've ever found. 👀 Today, I’m sharing my discovery of rebellious birds that build nests out of anti-bird spikes. And honestly, it's like telling a joke...

A thread. 🧵

But now the ultimate finding, as we discovered that there are birds who build their nest using anti-bird spikes!! 🤯 So last year I published a paper describing this behaviour: the ultimate adaption to city life! 🏙️

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.

I think it’s really important we collectively tomato the shit out of them until they reinstate these articles to show other academic societies that complying in advance with fascists is not going to be tolerated among the scientific community. Leadership should be ashamed of themselves.

Hey #WildlifeDisease & #conservation folk, please check out our survey on attitudes to parasite conservation.

Are parasites important for biodiversity, would you remove them to protect host welfare, or something more nuanced? We want to hear all views to improve guidance for practitioners 🪱🧪🌍🧵1/n
