Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change

open access: yesGlobal Change Biology, Volume 30, Issue 7, July 2024.
This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...

Opposing genetic patterns of range shifting temperate and tropical gastropods in an area undergoing tropicalisation

open access: yesJournal of Biogeography, Volume 51, Issue 2, Page 246-262, February 2024.
Abstract Aim The poleward range expansion of tropical species, and range contraction of temperate species (known as tropicalisation) has mainly been studied from an ecological perspective, with little research on its genetic consequences. Here, we used distributional and genetic data to document the consequences of tropicalisation in rocky shore ...

Repeated loss of the ability of a wild pepper disease resistance gene to function at high temperatures suggests that thermoresistance is a costly trait

open access: yesNew Phytologist, Volume 241, Issue 2, Page 845-860, January 2024.
Summary Specificity in plant–pathogen gene‐for‐gene (GFG) interactions is determined by the recognition of pathogen proteins by the products of plant resistance (R) genes. The evolutionary dynamics of R genes in plant–virus systems is poorly understood.
