(and big thanks to the awesome sea slug enthusiasts who helped us ID them and explained their crazy symbiosis)

A small brown sea slug in a petri dish alongside some green seaweed. Hard to see by the naked eye the sea slug has small green spots from the chloroplasts it extracts from algae.

Two specimens of E. viridis in a petri dish

What's cooler than a sea slug? A SOLAR POWERED SEA SLUG!!!

Elysia viridis are kleptoplasts, retaining chloroplasts from the algae they consume and using them for photosynthesis.

These two specimens were found in the rockpools at Filey, on a shore search survey with @yorkswildlife.bsky.social

super cool development in our understanding of co-extinction

Power, voice and participation: reflections on participatory methods and oral histories for community-based loss and damage assessments in Chikwawa, Malawi Following the establishment of the Fund for Responding to Loss and Damage at COP27, interest in community-based loss and damage (l&d) assessment methodologies has rapidly grown. Community-based l&d...

My first article is out in Climate and Development (and it's Open Access)! Based on data collection with one Malawian village, I examine how to build fairer and effective toolkits for community-based loss and damage assessments in post-disaster contexts.

Macro photo of a brown stink bug in face view on a leaf, guarding a tightly-clustered bunch of eggs that are shaped and colored exactly like a full tray of dark beer with foam on top.

Finally, the bug is back with a round of the Guinness.

🌊 Parasites are not always bad! In blue mussels (Mytilus edulis), trematode infection can buffer acute heat stress, linked to increased heat shock protein expression. A surprising twist on host-parasite interactions under warming conditions

Ectoparasites of electric eels are like buses - you wait your whole life for one and suddenly two turn up in a year!

Large model of a green caterpillar, the back of which is covered by dozens of white cocoons. Wasps can be seen emerging from some of the cocoons.

Spookiest decoration at the "Zoo Goes Boo" event at the John Ball Zoo in Grand Rapids? Giant model of parasitoid wasps hatching from cocoons affixed to their caterpillar host.

You probably have a general idea of what a tick looks like, but did you know that there are three distinct families of ticks, each with their own appearance, habitat, and adaptations? These families are the Ixodidae (or hard ticks), Argasidae (or soft ticks), and the Nuttalliellidae. (1/4)

No cover yet, but there's a web page. Incredibly pleased to be part of this important - and affordable! - volume on extinction studies. Pre-order now because I promise it will be good

checking a species name with GBIF after not finding it via NCBI feels very much like the asking your Dad after your Mum already told you "No" of taxonomy

weren't you meant to post this after our paper review meeting this afternoon?

An interdisciplinary approach to improving conservation outcomes for parasites Parasites represent a significant proportion of Earth's biodiversity and play important roles in the ecology and biology of ecosystems and hosts, making them an important target for conservation. Des...

...and failing that, hopefully you can find out about some new species of delightful/disgusting worms and ticks

Parasites are ecological dark matter – and they need protecting Save the pandas, sure, but what about the worms in their guts?

We wrote this as a fun introduction to the strange and wonderful world of parasite conservation!

Hopefully it gets you thinking about how there's more than meets the eye with parasites and whether we should bring them into the fold of conservation concern

Save the pandas, sure, but what about the worms in their guts?

my extremely nuanced opinion on the woolly mice is that they are very cute (good), but mean basically nothing as far as conservation is concerned (less good) and are really just a PR exercise for a somewhat malevolent profit-making machine (bad)

Am I right in thinking that Colossal's (non-)conservation work allows them to patent a lot of genetic technology which they could then make massive profits from if/when those technologies are used for wider applications than woolly mammoth PR?

Paleorecords Reveal Biological Mechanisms Crucial for Reliable Species Range Shift Projections Amid Rapid Climate Change Climate change has created an urgent need for reliable projections of species distributions. By hindcasting forest tree range shifts across Europe over the last 12,000 years, we show that process-exp...

Ever wondered how reliable species distribution models (SDMs) are in the face of climate change compared to more mechanistic approaches? We did too, and our results are now published in Ecology Letters ⏬

Interdisciplinary research is not only hugely valuable, it's also a hell of a lot easier than people make out - the hard part is fighting the institutions to get them to let you do it

In my section, I talk about:
- my own taxonomic biases in the field
- the mighty Manx shearwater flea
- the role of photography in conservation
- and whether photography might boost or buffer parasite conservation

(including a rare opportunity for me to cite the great John Berger...)

Really excited to share this paper which was the result of a big collaborative effort of PhD students @extinctionleeds.bsky.social!

It's full of incredible, original thoughts about how we view and interact with the world around us in a time of massive biodiversity loss 📷🍃

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

Saving the Ryukyu Rabbit Tick: The Posterchild of Parasite Conservation • The Revelator This endangered invertebrate is harmless to humans — and rabbits. Saving it from extinction might even benefit both species.

Parasite conservation sounds like a counterintuitive idea, but actually there are lots of reasons why this is important for the long term sustainability of biodiversity and ecosystem processes. #parasitology #ticks #ectoparasite 🪱🧪🌍

We consider:
- The importance of human values and attitudes for conservation
- Unanswered questions over whether parasites merit conservation

Our solution? More interdisciplinary research on parasite conservation will lead to better conservation outcomes for parasites, hosts, and people 🌳🌍🥰
