High MHC gene copy number maintains diversity despite homozygosity in a Critically Endangered single‐island endemic bird, but no evidence of MHC‐based mate choice

Molecular Ecology, Volume 29, Issue 19, Page 3578-3592, October 2020., 2020
Abstract Small population sizes can, over time, put species at risk due to the loss of genetic variation and the deleterious effects of inbreeding. Losing diversity in the major histocompatibility complex (MHC) could be particularly harmful, given its key role in the immune system.

Modeling Predator–Prey Linkages of Diadromous Fishes in an Estuarine Food Web

Marine and Coastal Fisheries, Volume 8, Issue 1, Page 476-491, January 2016., 2016
Abstract Historically, multiple species of diadromous fishes served as a coastal food source for commercially valuable nearshore predators. However, severe declines in diadromous fish populations in the nearshore Gulf of Maine (GOM) have impacted trophic dynamics and increased pressure on other estuarine‐dependent forage resources.
