Automated Profiling of Social Behaviors to Assess the Genetic Basis of Evolution of Aggressive Behaviors in Astyanax mexicanus

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Across the animal kingdom, social behaviors such as aggression are critical for survival and reproductive success. While there is significant variation in social behaviors within and between species, the genetic mechanisms underlying natural variation in social behaviors are poorly understood.

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

Ion Activation Methods for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Sound from spawning cod at their spawning grounds [PDF]

open access: yesICES Journal of Marine Science, 1999
Sound was recorded at five stations at and near the main spawning grounds of the northeast Arctic cod (Gadus morhua L.) off the Lofoten Islands, Norway. Recordings were carried out during April 1997 when large numbers of cod aggregated to spawn, and were repeated in September when the cod were no longer spawning and, in fact, most had emigrated.

Archaeological and Biogeochemical Investigation of Past Human Relationships With Now‐Endangered Fish Species: Lake Sturgeon and American Eel in Southern Ontario, Canada

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper explores the historical ecology and biogeography of two fish species that are currently endangered in the North American Great Lakes region, that were of great importance to the Indigenous people in the region, and that are the focus of ongoing conservation efforts on the part of descendant communities: lake sturgeon (Acipenser ...
