Effects of protection and temperature variation on temporal stability in a marine reserve network

Conservation Biology, Volume 38, Issue 3, June 2024.
Abstract Understanding the drivers of ecosystem stability has been a key focus of modern ecology as the impacts of the Anthropocene become more prevalent and extreme. Marine protected areas (MPAs) are tools used globally to promote biodiversity and mediate anthropogenic impacts.

Clams in north-patagonian gulfs, Argentina: Trophic offer for migratory shorebirds [PDF]

, 2013
Peninsula Valdes, Argentinian Patagonia, is an area used as a trophic stopover by several shorebird species. These shorebirds are characterized by made long migrations and their survival depend for the sites where they stopover to forage.

Plant phylogenetic diversity influences arthropod communities in tropical forest restoration plots

Biotropica, Volume 56, Issue 3, May 2024.
We assessed the impact of plant phylogenetic diversity on arthropod communities in 12 experimental restoration plots with either high or low plant phylogenetic diversity. Arthropods with different feeding habits (herbivores, predators, pollinators, and detritivores) were collected after 1 and 3 years and were identified as morphospecies or operational ...

Future climate‐induced distribution shifts in a sexually dimorphic key predator of the Southern Ocean

Global Change Biology, Volume 30, Issue 3, March 2024.
Climate change poses challenges for sexually dimorphic species, such as the Antarctic fur seal, where males are larger than females. By tracking individuals from both sexes, we assessed their responses to current environmental conditions and projected their future responses using various climate models. Findings reveal a sex‐skewed impact: females face

Lipid biomarkers reveal trophic relationships and energetic trade‐offs in contrasting phenotypes of the cold‐water coral Desmophyllum dianthus in Comau Fjord, Chile

Functional Ecology, Volume 38, Issue 1, Page 126-142, January 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Benthic suspension feeders like corals and sponges are important bioengineers in many marine habitats, from the shallow tropics to the depth of polar oceans. While they are generally considered opportunistic, little is known about their actual in situ diet.
