Metabolism, movement behaviour, and salinity responses of invasive mosquitofish compared with a threatened toothcarp
The success and impact of invasive non-native species depend on how they cope with local abiotic conditions, especially in comparison to co-occurring native taxa. In aquatic systems, salinity serves a...

🧵1/9 There are 35,000+ fish species, but we have formal social-behaviour classifications for a tiny fraction. Most knowledge lives in the experience of researchers, fishers, divers, aquarists, naturalists, and Indigenous communities, but almost none of it is centralised. So we built ShoalBase.org.

How is soil functioning shaped by aridity? 🌲🌵 We studied this along a natural aridity gradient.
📌 Microbial structure shifted with aridity, but soil functions were mainly driven by local soil properties.
