#macroinvertebrate question for the experts. This Predacious Diving Beetle has something growing on it. No other PDB had it. Sort of feathery white growth. Wondering if anyone knows what it is? #ephemeralpond #wetlands

Effects of agricultural land conversion and interstitial sediment on Tasmanian stream macroinvertebrate communities Macroinvertebrate communities are expected to change with agriculture but the predicted strengths and directions of effects on communities are unclear. We

🪲 🪱 🌳 WSL researchers sampled tree holes in France, Brazil and India and found that spatial structuring explained #macroinvertebrate diversity better than local conditions, highlighting the importance of connectivity and old-growth forests for conservation. onlinelibrary.wiley.com/doi/10.1111/...

Many #macroinvertebrate holotypes of the Santana Group are deposited and ultimately described in foreign institutions. This new study examines the ongoing loss of Brazil’s cultural and scientific heritage and proposes strategies to prevent and mitigate the impact of parachute science.

I had the wonderful opportunity to present my research on the drivers of macroinvertebrate taxa & functional traits in vernal ponds at the annual @freshwaterscience.bsky.social meeting this past week! I hope everyone who joined “Club Pond” had a wonderful time 😊

21st year of annual aquatic #Macroinvertebrate sampling in the Burrishoole catchment index sites 😊😊
Great help from my three amigos @JoshkaKaufmann @ThibautDugay @MaxwellHugo 🪲🪳🪱🪰 and some curious onlookers. Water levels were very low and temperature were very high 🙄
