A World for Reactive Phenotypes

Autores: Geoffroy, Benjamain; Alfonso, Sebastien; Sadoul, Bastien; Blumstein, Daniel T.
Humans currently occupy all continents and by doing so, modify the environment and create novel threats to many species; a phenomenon known as human-induced rapid environmental changes (HIREC). These growing anthropogenic disturbances represent major and relatively new environmental challenges for many animals, and invariably alter selection on traits adapted to previous environments. Those species that survive often have moved from their original habitat or modified their phenotype through plasticity or genetic evolution. Based on the most recent advances in this research area, we predict that wild individuals with highly plastic capacities, relatively high basal stress level, and that are generally shy—in other words, individuals displaying a reactive...

Zebrafish      Danio rerio     shows behavioural cross‐context consistency at larval and juvenile stages but no consistency between stages

Coping style is defined as a set of individual physiological and behavioural characteristics consistent across time and context. In the zebrafish Danio rerio, as well as in many other animals, several covariations have been established between behavioural, physiological, and molecular responses. However, not many studies have addressed the consistency of behavioural responses over time starting at the larval stage. Therefore, we aimed to improve our understanding of behavioural consistency across context and over time in zebrafish from the larval to juvenile stages. We conducted two distinct experiments: a larval stage experiment (from 8 to 21 days post fertilization, dpf) and a juvenile stage experiment (from 21 to 60 dpf). On one hand, the larval...

Nature-Based Tourism Elicits a Phenotypic Shift in the Coping Abilities of Fish

Nature-based tourism is gaining extensive popularity, increasing the intensity and frequency of human-wildlife contacts. As a consequence, behavioral and physiological alterations were observed in most exposed animals. However, while the majority of these studies investigated the effects of punctual exposure to tourists, the consequences of constant exposition to humans in the wild remains overlooked. This is an important gap considering the exponential interest for recreational outdoor activities. To infer long-term effects of intensive tourism, we capitalized on Odontostilbe pequira, a short-lived sedentary Tetra fish who spends its life close to humans, on which it feeds on dead skin. Hence, those fish are constantly exposed to tourists throughout their...
