Article Synopsis
  • - Demographic changes in fish populations are often influenced by environmental factors, particularly climate shifts, but deep-pelagic fishes are thought to be stable in their habitats.
  • - A study examined the demographic histories of 11 deep-pelagic fish species using DNA data, revealing that many have experienced population expansions despite the expected stability of their environment.
  • - The findings indicate that deep-pelagic fishes, which are among the most numerous vertebrates on Earth, may still be significantly affected by past climatic changes, signaling a need for further research on their responses to future climate challenges.

The scalloped hammerhead shark, , is a Critically Endangered, migratory species known for its tendency to form iconic and visually spectacular large aggregations. Herein, we investigated the population genetic dynamics of the scalloped hammerhead across much of its distribution in the Eastern Tropical Pacific (ETP), ranging from Costa Rica to Ecuador, focusing on young-of-year animals from putative coastal nursery areas and adult females from seasonal aggregations that form in the northern Galápagos Islands. Nuclear microsatellites and partial mitochondrial control region sequences showed little evidence of population structure suggesting that scalloped hammerheads in this ETP region comprise a single genetic stock.

Article Synopsis
  • The text discusses the growing interest in deep-sea mineral resources, particularly seafloor massive sulphides, and the increasing number of exploration licenses issued in the Indian Ocean.
  • It outlines a research project conducted from 2013 to 2018 that aimed to study the megafauna of the Central Indian Ridge and South East Indian Ridge, particularly the non-vent species which were previously under-researched.
  • This project resulted in the identification of 218 taxa based on imagery and additional confirmation of 20 taxa through sampling, creating a comprehensive catalogue of megafauna and their distribution in the region.

Sponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. While strong patterns of host specificity have been observed consistently in sponge microbiomes, the precise ecological relationships between hosts and their symbiotic microbial communities remain to be fully delineated. In the current study, we investigate the relative roles of host population genetics and biogeography in structuring the microbial communities hosted by the excavating sponge .

Tropical storm intensity prediction remains a challenge in tropical meteorology. Some tropical storms undergo dramatic rapid intensification and rapid decline. Hurricane researchers have considered particular ambient environmental conditions including the ocean thermal and salinity structure and internal vortex dynamics (e.

Threatened Caribbean coral communities can benefit from high-resolution genetic data used to inform management and conservation action. We use Genotyping by Sequencing (GBS) to investigate genetic patterns in the threatened coral, , across the Florida Reef Tract (FRT) and the western Caribbean. Results show extensive population structure at regional scales and resolve previously unknown structure within the FRT.

Marine sponges are vital components of benthic and coral reef ecosystems, providing shelter and nutrition for many organisms. In addition, sponges act as an essential carbon and nutrient link between the pelagic and benthic environment by filtering large quantities of seawater. Many sponge species harbor a diverse microbial community (including Archaea, Bacteria and Eukaryotes), which can constitute up to 50% of the sponge biomass.
