- Check out our new paper on salinity effects on metabolism and movement in #invasive mosquitofish and the threatened Spanish toothcarp! Huge thanks to all the co-authors: @garciaberthou.bsky.social, @jollewjolles.bsky.social, Cesc, and Anna.🐟🔝 @greco-udg.bsky.social @iea-udg.bsky.social
- How do #invasivespecies outcompete #native ones when #environmental conditions change? 🔬New #research on the #invasive Eastern Mosquitofish (𝘎𝘢𝘮𝘣𝘶𝘴𝘪𝘢 𝘩𝘰𝘭𝘣𝘳𝘰𝘰𝘬𝘪) and the endangered Spanish Toothcarp (𝘈𝘱𝘩𝘢𝘯𝘪𝘶𝘴 𝘪𝘣𝘦𝘳𝘶𝘴) sheds light on the physiological mechanisms at play ⤵️ doi.org/10.3897/neob...
- Toothcarp maintained metabolic performance across salinities, while mosquitofish showed lower aerobic performance at elevated salinity.
- Mosquitofish spent more time moving and used space more uniformly, whereas toothcarp showed more restricted, stop–go movement, shedding light on differences in ecological strategy and invasion success.
