Article Synopsis
- The deep reef refugia hypothesis posits that deeper areas of a reef are less affected by disturbances, providing a refuge for fish populations from shallower zones; however, this study in the Gulf of California challenges that idea.
- Researchers investigated fish diversity across shallow and mesophotic reefs using video recordings and analyzed various biological traits and indices to measure diversity and functional roles of fish species.
- Findings revealed greater taxonomic richness in shallow reefs but similar functional roles in both zones, indicating a connection between shallow and mesophotic reefs despite differences in species diversity likely due to varying environmental conditions.
Multi-use marine protected areas (MUMPAs) are a commonly applied tool for marine conservation in developing countries, particularly where large no-take reserves are not socially or politically feasible. Although MUMPAs have produced benefits around the world, the persistence of moderate fishing pressure reduces the likelihood of achieving the primary objective of these areas, which is the conservation of ecosystems. In this study we used traditional and functional metrics to evaluate how fish assemblages changed through time in a MUMPA, including shifts in species responses and in ecological processes.
View Article and Find Full Text PDFOur study provides a checklist of 36 crustacean decapods from the Mexican tropical Pacific coastline. Most of the species were previously recorded from coral communities in the Gulf of California. Data were obtained by visual censuses of coral communities and some specimens were collected by extractions of coral branches (approximately eight liters of coral volume).
