Interactions between spatial dynamics and stock structure in marine fishes have largely focused on stocks in decline; stock structure is rarely re-visited for expanding species. Here, the spatial e...

Between 1997 and 2011, The National Marine Fisheries Service conducted 50 depletion experiments to estimate survey gear efficiency and stock density for Atlantic surfclam (Spisula solidissima) and ocean quahog (Arctica islandica) populations using co

In this study, we assessed the Atlantic surfclam (Spisula solidissima) energy budget under different ocean acidification conditions (OA). During 12 weeks, 126 individuals were maintained at three different ρCO2 concentrations. Every two weeks, indiv

The ocean quahog Arctica islandica is an extremely long-lived and slow-growing marine bivalve that supports fisheries in several countries bordering the northern Atlantic ocean. The life history of the ocean quahog presents several unique challenges

Deuterium oxide dilutions have long been the accepted means for collecting body condition measures on phocids. Blubber depth has become more frequently used as an indicator of health. This project represents the first in-depth examination of blubber

Generalized linear mixed models were developed for allometric relationships in Atlantic sea scallops (Placopecten magellanicus). These models used environmental covariates such as depth, latitude, geographic area, fishing pressure, population density

Steller sea lions (Eumetopias jubatus) have experienced a decline in Russia as well as the United States. The causes for the decline of the Russian population may or may not overlap the causes of the decline in Alaska. The demographics of the Russian
