We identify three major areas where change is possible:
1. Rethinking research evaluation
2️. Strengthening training & mentorship
3️. Reducing and recognizing administrative tasks

The experiment also demonstrated that the interspecific effects of mosquitofish on toothcarp were more important than those of intraspecific competition. The invasive species produced effects on population growth rate, size structure, and fish condition (mass-length relationship) of toothcarp.
Figure 5. Violin plots with the kernel probability densities of the total length of toothcarp (A) and mosquitofish (B) by sex at the start (30 May 2022) and the end (14 July) of the experiment. The six treatments were: toothcarp at low density (T_low); mosquitofish at low density (M_low); toothcarp at high density (T_high); mosquitofish at high density (M_high); toothcarp and mosquitofish at high densities together (Mixed); and toothcarp and mosquitofish at high densities separated with a net (Net).

The diversity of effects of mosquitofish underscores the difficulty of predicting the impact of #bioinvasions. We further provide an approach to differentiate the effects of resource competition from other more direct ecological interactions & so to clarify the impact mechanism of #bioinvasions. 🌎
Figure 6. Relationship between total mass and total length (condition) for toothcarp at the end of the experiment by treatment and sex. The linear regression functions are shown. The six treatments were: toothcarp at low density (T_low); mosquitofish at low density (M_low); toothcarp at high density (T_high); mosquitofish at high density (M_high); toothcarp and mosquitofish at high densities together (Mixed); and toothcarp and mosquitofish at high densities separated with a net (Net).

Insightful talk today by @oldenfish.bsky.social @uwsafs.bsky.social at @iea-udg.bsky.social @univgirona.bsky.social on bounty programs as a management strategy for native and non-native species
