Fine-Scale Population Genomics Reveals Genetic Differentiation in the Brooding Amphipod <i>Cheirimedon femoratus</i> Across the South Shetland Islands, Antarctica. [PDF]

open access: yesEcol Evol
Using genotyping‐by‐sequencing‐derived single‐nucleotide polymorphisms, we investigated population connectivity in the Antarctic benthic amphipod Cheirimedon femoratus across the South Shetland Islands. Despite the limited dispersal potential of this brooding species, populations showed substantial genetic connectivity, likely maintained through ...

Seabird Prey in Space and Time: Combining Multiple Datasets to Model the Distribution of Sandeel (<i>Ammodytes marinus</i>) and Sprat (<i>Sprattus sprattus</i>) in the North Sea. [PDF]

open access: yesEcol Evol
Forage fish are key prey and commercial species in the North Sea ecosystem, but estimates of their biomass over detailed spatial and temporal scales is currently limited. To fill this vital research gap we employ Hierarchical Bayesian spatiotemporal models of sandeel (Ammodytes marinus) and sprat (Sprattus sprattus) in the North Sea, providing fine ...
