The recently formed IUCN Parasite Specialist Group has just launched a Bluesky account. Give them a follow to get news about the conservation and amazing biology of parasites. Many parasite species are co-endangered with their hosts and need more conservation attention. 🌍🧪🪱
Hello, Bluesky! We're the IUCN SSC Parasite Specialist Group, a part of the Species Survival Commission! We're just starting to understand the important roles parasites play in their ecosystems, and our goal is to determine the threats wildlife parasites face and to conserve rare and unique species!

For @biographic.bsky.social, writer @craigwelch.bsky.social followed @hakai.org scientist @rhizalyssa.bsky.social's quest to unveil the the killer that decimated populations of sea stars off the West Coast. It took a few years but the lab's hard work paid off: www.biographic.com/unmasking-th...
Unmasking the Sea Star Killer
After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

🧬🐛 What can parasites teach us about food webs?
Stable isotope analysis (SIA) as a powerful tool now also in parasitology! Our chapter dives into how SIA and compound-specific SIA (CSIA) reveal what parasites eat and how they impact hosts metabolism and entire food webs. doi.org/10.1007/978-...

NEW! 🎉 We need wildlife disease surveillance to predict epidemics, but data sharing is rare - we found that only 2-3% of studies share raw data. So, we spent three years developing a data standard and R package to help get wildlife disease data into FAIR repositories. www.nature.com/articles/s41...

Two Barnacles, One Crab: 🦀
I've written a post about a pair of parasitic barnacles that infect spider crabs.

These barnacles grow roots that spread throughout the crab's body, some of which make their way into the host's brain.
