Dietary and habitat niche partitioning in congeneric cryptobenthic reef fish species
Contact: SIMON BRANDL | Coral Reefs

ABSTRACT
Ecological niches hold critical information concerning the eco-evolutionary dynamics that govern biodiversity and abundance patterns. Cryptobenthic reef fishes account for approximately half of all reef fish species and are an abundant and important group on coral reefs worldwide. Yet, due to their small size and inconspicuous lifestyles, relatively little is known about the ecological niches of most cryptobenthic species. Here, we use gut content DNA metabarcoding to determine dietary niche overlap and prey richness in four sympatric species of cryptobenthic reef fishes in two genera (Acanthemblemaria aspera, A. spinosa, Enneanectes altivelis, and E. matador)...more

Mass mortality in a Marine Educational Area on a remote South Pacific Atoll
Contact: DAVID LECCHINI | Marine Pollution Bulletin

ABSTRACT
In 2018, on the isolated Anaa atoll (South Pacific), a Marine Educational Area (MEA) was established by the local community to protect fisheries resources on the reef barrier next to their village. Whilst the remote location of the small MEA has provided some protection from anthropogenic pressures due to distance and low population, we showed that from 26 to 27 November 2018, high temperatures along with a hypoxic event and a low tide led to the mass mortality of several Anaa's marine species. The mass mortality in the MEA (area: 27,000 m2) included >14,000 juvenile fish, 1300 adult fish, 5100 juvenile crustaceans, and 260 juvenile octopus. This finding is particularly concerning because despite the creation of a MEA to protect marine resources, impacts from the warming waters associated with climate change limited the local efforts in Anaa atoll...more
