Pisionidens Aiyar & Alikuhni, 1943 is a genus of small scale-less annelids formerly belonging to the family 'Pisionidae', now synonymized with the scale worm family Sigalionidae. A new species from Akumal, México, Pisionidens ixazaluohae n. sp., is herein described, including a genetic barcode, and diagnosed by parapodia from segment 8, males having a continuous line of midventral pores, and the presence of a single copulatory segment without parapodia. The new species differs in morphology from the three previously described species, including P. indica (Aiyar & Alikuhni, 1940), representing the only other species previously reported from the Caribbean Sea and Gulf of Mexico. A comparative table with a summary of the main taxonomic characters of all described species of the genus, including information on distribution, is provided.

Tourism, urban development, and sargasso beaching caused environmental alterations in the Mexican Caribbean coasts. Little ecotoxicological information exists on the green turtle (Chelonia mydas) population inhabiting this region. Micronucleus (MN) and erythrocytic nuclear abnormalities (ENA) tests are non-destructive DNA damage biomarkers.

Sex determination in monomorphic birds is a precondition for captive breeding programs and management and conservation strategies for threatened species. Most species of the order Psittaciformes often present complications since these birds lack external sexual phenotypic traits, making it impossible to differentiate males and females. In the present study, we used molecular techniques to determine the sex of 31 individuals belonging to nine species of the order Psittaciformes kept under human care at the Akumal Monkey Sanctuary & Rescued Animals in Quintana Roo, Mexico.

The resident and tourist population in the Mexican Caribbean has grown exponentially, increasing the availability of dissolved inorganic nutrients in coastal waters through submarine groundwater discharge (SGD). Recently, a new massive drift of Sargassum spp. has occurred that can provide new organic matter and enrich coastal water with nutrients.

Coral diseases acting synergistically with other environmental stressors are a growing problem for Caribbean reefs. Hard coral cover, coral traits, and coral diseases were examined from 1999 to 2021 for Akumal reef, located in the Northern Mexican Caribbean. The 45 recorded coral species were classified into life-history strategies: competitive, stress-tolerant, and weedy, associated with different framework-building capacities.
