A new group dedicated to evolutionary ecology! This is an opportunity to have a permanent community space for the field, as well as ensure regular conferences like #ExE2026. But it needs your help 👇

BES Evolutionary Ecology Group@bes-evolecol.bsky.social · last mo.

We’re now looking for evolutionary ecologists to join our committee to build #ExE2026 into the start of something great, not just a one-off. Details here: www.britishecologicalsociety.org/content/evol...

Evolution and Ecology meet in talks of the #ExE2026 conference from the microbiome to behaviour. Great contributions to the understanding to the ability of wild species to adapt by using quantitative genetics. Looking forward to 2027 edition

Our latest publication on planktivorous fishes! In this article, we highlight the long-term stability of these fishes to fluctuations in coral cover at Mo’orea, French Polynesia. #fish #coralreefs #MarineEcology @benoitpujol.bsky.social @renatoamorais.bsky.social

Planktivorous fishes withstand 20 years of major coral cover oscillations - Coral Reefs

Planktivorous fishes play a crucial role in coral reef ecosystems by converting pelagic planktonic resources into reef biomass. They serve as key vectors of energy transfer from the pelagic zone to the reef, thereby enhancing overall reef productivity. However, the habitats supporting planktivorous fishes are under unprecedented stress imposed by global changes, foremost of which is widespread warming-induced coral mortality. We analyzed 20 years (2004–2024) of benthic and fish monitoring data around Mo’orea Island (French Polynesia, South Pacific) across three reef types (fringing reef, back reef, and fore reef). Our results show that planktivorous fish density was positively but weakly correlated with coral cover. On the fore reef, planktivorous fish communities were more responsive to disturbances affecting coral cover (e.g., heatwaves, cyclones, or crown-of-thorns starfish outbreaks). There, fishes responded by exhibiting relatively large fluctuations in density and community composition; the opposite was true for the back reef and fringing reef. Indeed, zones characterized by low coral cover (< 25%) that initially supported few planktivorous fishes, showed a moderate but detectable increase in density after successive disturbances. We show that oscillations in coral cover driven by these disturbances may have long-term cascading effects on associated fish assemblages, as evidenced by the gradual decline of Pycnochromis vanderbilti unveiled in our study. Collectively, our findings imply a relative resilience of planktivorous fishes facing repeated and severe coral cover decline and rebound.

Les suivis de la capacité d'adaptation des plantes c'est toute l'année, même quand il faut traverser l'eau en waders avec un vent à décorner les boeufs ! Merci à mon complice de toujours Fabien Morat, et à SEE-Life CNRS d'avoir labelliser notre suivi de plus de 15 ans
