Are threatened species important for glueing interaction networks together?
González-del-Pliego, Pamela; Galiana, Nuria; González-Trujillo, Juan David; Mestre, Frederico; Bastos Araújo, Miguel; Bastazini, ViniciusBiotic interactions are a critical element for the functioning and the stability of ecosystems, yet anthropogenic pressures can significantly disrupt these networks of interacting species. While species-focused conservation is central to most conservation policy, it is also vital to identify the interactions at risk and the ones that play a disproportionate role in glueing communities together. Here we assess t...
Exposure of protected areas in Central America to extreme weather events
González-Trujillo, Juan David; Alagador, Diogo; González-del-Pliego, Pamela; B. Araújo, MiguelCentral America and the Caribbean are regularly battered by megadroughts, heavy rainfall, heat waves, and tropical cyclones. Although 21st-century climate change is expected to increase the frequency, intensity, and duration of these extreme weather events (EWEs), their incidence in regional protected areas (PAs) remains poorly explored. We examined historical and projected EWEs across the region based on 32 me...
Trophic convergence of marine vertebrate communities worldwide
González-Trujillo, Juan David; Assis, Jorge; Serrao, Ester A.; Costello, Mark John; Fragkopoulou, Eliza; Mendoza, Manuel; Araújo, Miguel B.Biogeographic regions arise due to constraints on species ranges, fostering lineage divergence as a result. Yet, convergent evolution means that evolutionary distinct lineages can share similar characteristics when subjected to similar environmental conditions. The ecological convergence of distinct regions has been demonstrated in terrestrial communities, but it remains uncertain if marine systems exhibit simi...

Extreme weather events threaten biodiversity and functions of river ecosystems:...
Sabater, Sergi; Freixa, Anna; Jimenez, Laura; López-Doval, Julio; Pace, Giorgio; Pascoal, Cláudia; Perujo, Núria; Craven, DylanBoth gradual and extreme weather changes trigger complex ecological responses in river ecosystems. It is still unclear to what extent trend or event effects alter biodiversity and functioning in river ecosystems, adding considerable uncertainty to predictions of their future dynamics. Using a comprehensive database of 71 published studies, we show that event - but not trend - effects associated with extreme cha...
