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!

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...
The title of the paper: "A minimum data standard for wildlife disease research and surveillance" - and an example data table

In a synthesis of over 3000 population trends in the Wadden Sea, we show a substantial reorganization of biodiversity with over 38% of populations undergoing significant change (i.e., increases or decreases), identify winners and losers and critical time points of change! dx.doi.org/10.1111/gcb....

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.

Sacculina pilosella is a parasite of spider crabs ( Scyra ferox ), and while it is technically a barnacle, you're going to have to abandon ...
