NEW RESEARCH 🚨 Researchers identify ultrasonography as reliable method of determining sex in migrating silver eels. This technique was shown to be more reliable than molecular marking, and removes the need for sacrifice. @mjw-marine.bsky.social onlinelibrary.wiley.com/doi/10.1111/... 🦑🧪🌍🦤🌐
Non-lethal tools for accurate sex identification in European #eel are required. Our new #OpenAccess paper shows ultrasonography is an accurate, non-lethal tool for identifying sex, but molecular markers were less reliable. Link here ▶️ www-tinyurl.com/b414e8a2 @zslscience.bsky.social #Science
Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla
Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or th...

New paper out! 📢 We tested whether boat activity from an eel telemetry study disturbed protected waterbirds in a UK reservoir. 🦆 No evidence of disturbance. 🌦️ Bird numbers varied with weather + season. conbio.onlinelibrary.wiley.com/doi/10.1111/...
The impact of boat activities associated with an acoustic fish telemetry study on waterbird populations in a Special Protection Area
It is widely recognized that the research techniques used to monitor and study wildlife have the potential to disturb and alter the behavior of the study species. However, other impacts on sensitive,...

In this month's blog post, I demonstrate how to visualize shipping traffic data using R. The tutorial covers downloading the dataset from EMODnet, performing exploratory data analysis, and creating a map using ggplot2. #Rstats #GeospatialAnalysis #DataVisualization #ShippingTraffic
Herculean collation of >12K megafauna tracks, >100 species, reveals 75% overlap of critical habitats with shipping, fishing, pollution or warming. Protection targets not enough to safeguard megafauna. New paper in @science.org, led by @anammsequeira.bsky.social 👇 📸silvana-palacios,daniel-torobekov

Great to see our new paper on the impacts of water flow and crest shape on juvenile #eel movement on fish passes now out in the Journal of #Fish #Biology! #openaccess #science #freshwater @zslscience.bsky.social @jack-brand.bsky.social @ucl.ac.uk onlinelibrary.wiley.com/doi/10.1111/...
Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration
River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endan...

Super happy to see our new article on how pharmaceutical pollution can influence salmon migration out in @science.org! This was a huge effort by a great team of researchers over the last few years! You can read the paper here: science.org/doi/10.1126/sc…!
Nice new paper out reviewing the use of #biologging as a platform for monitoring environmental threats and aiding marine management. Also introduced me to the term Internet of Animals, which made me happy #science #behaviour #Marine www.sciencedirect.com/science/arti...

Great new paper out on the impacts of pharmaceutical pollution in salmonids by @jack-brand.bsky.social and colleagues.
Jack A Brand@jack-brand.bsky.social · 2y agoFirst data paper from my postdoc is now out in Proc B! We found that psychoactive pollution decreased the migration success of brown trout in a natural lake system! Massive thanks to the coauthor team for their work on this! Paper 👉 tinyurl.com/yn77u2nb
First post on #Bluesky, thought I'd highlight some of our research this year with @netlab.bsky.social. Acoustic telemetry can be used to answer a whole variety of questions including; Residency in reef #sharks - doi.org/10.1038/s420...
Environmental stress reduces shark residency to coral reefs - Communications Biology
Environmental stress on coral reefs is increasing. Authors show a stress-related reduction in residency of grey reef sharks on the remote reefs of the Chagos Archipelago, promoting more diffuse space ...
