Lamentable: hay info suficiente lo que falta es voluntad para afrontar problemas difíciles pero importantes. Por desgracia, los intereses económicos de unos pocos siempre pasan por los problemas ambientales de tod@s 🥲

Figure 3. Redundancy analysis of the seven behavioural variables (black arrows) with metabolic traits (blue arrows) as constraints in toothcarp (see Suppl. material 3: fig. S6 for the plot for mosquitofish). Each red dot represents an individual.
Metabolism–behaviour link: in toothcarp, movement was more related to baseline metabolism (SMR), with individuals with higher SMR moving less. In mosquitofish, metabolism explained little of the behavioural variation.
Figure 2. Box-plots of movement behavioural variables of mosquitofish (purple) and toothcarp from both sexes (yellow) pooled across salinity treatments. Metrics include the proportion of time near edges, median speed, proportion of time stationary, median turning speed, proportion of time sharply turning (> 45 °/s), proportion of arena visited, and the coefficient of variation (CV) of arena use.
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.
Figure 1. Box-plots of metabolic responses (SMR, MMR, FAS, and AAS) for female mosquitofish (purple), female toothcarp (green), and male toothcarp (yellow) across salinity treatments.
Toothcarp maintained metabolic performance across salinities, while mosquitofish showed lower aerobic performance at elevated salinity.

🧵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.
We’re offering a fully funded 4 yr PhD position to work on Sexual selection in complex environments at the @uv.es. Co-supervised by @dbergerbiol.bsky.social. Find details below 👇

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.
