Back from the break! We have Joana Martelo, who tells us about her research looking at beta diversity. Pools with low species number and high species number have a high contribution to #BetaDiversity. Drying and #damming lead to native #SpeciesLoss. Fragmentation drives non-native species replacement. Diversity was driven by local environment in native #fish, but driven by spatial fragmentation in non native fish #FSBI2025

Highlights work by Barros et al which examined the impact of #damming caused by road construction in the #Amazon
https://doi.org/10.1111/JFB.15906

What they found is, #fish in #dam habitats became more specialised to the limited resources, rather than becoming more generalist.

California regulators seek replacement of tire chemical linked to fish kills

Several waters were found to have concentrations of 6PPD-quinone that are harmful to fish, including a site near the Kerner Pump Station in San Rafael as well as in San Jose, Oakland and Contra Cos…
