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.

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 ...

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.
