A Review of the Status of Sharks, Rays and Chimaeras of Panama to Guide Research and Conservation
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.ABSTRACT Chondrichthyan fishes (sharks, rays and chimaeras) are a group of high conservation concern globally. Species are impacted by varying threats, although fishing pressure is the primary stressor causing population declines. Panama comprises both Pacific and Caribbean coastlines with a diversity of estuarine and marine habitats supporting small ...

Basin Research, Volume 37, Issue 1, January–February 2025.ABSTRACT Orogenic wedges juxtapose tectonic units that originated far from each other, and tracing these back to their origin is often difficult. We have studied two contrasting serpentinite–sediment associations of the Alpine‐Apennine orogenic wedge of eastern Elba Island with the help of a detrital zircon study of the sediments and a geochemical ...

Diversity and Distributions, Volume 30, Issue 9, September 2024.Abstract Aim Coralligenous reefs are the main marine bioconstructions in terms of spatial distribution within the Mediterranean basin. Two distinct reef morphologies can be distinguished based on the surface and topographical features of the seafloor: cliffs developing vertical slopes and banks found on gently steep or horizontal bottoms. Despite their

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change
Global 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 ...
