San Francisco Estuary mysid abundance in the fall, and the potential for competitive advantage of Hyperacanthomysis longirostris over Neomysis mercedis

California Fish and Wildlife Journal, 2020
Historically, the native mysid Neomysis mercedis was a key source of food for fish in the San Francisco Estuary (SFE). Following the introductions of the over-bite clam and many invasive zooplankton species in the mid-1980s, populations of native ...

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Global length–weight relationships of deep‐pelagic fishes: Coverage, biases and variability

Journal of Fish Biology, EarlyView.
Abstract Length–weight relationships (LWRs) are morphometric tools that allow body mass to be estimated from fish length, providing input for fisheries, ecological and biodiversity studies. For deep‐pelagic fishes, however, LWR data remain fragmented and unavailable for most species.

Study on Dynamic Characteristics and Fracture Failure of Rigid Truss Trawl System During Towing Process

Journal of Marine Science and Engineering
Deep-sea fisheries depend on various fishing methods, including trawling, purse seining, and longline fishing, among others. Studying the dynamic characteristics of trawling operations is essential for the trawl mechanism.

Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

Local Surface and ENSO Forcings Induce Predictable Temperature and Salinity Responses in the Coastal Gulf of Alaska

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract We assess temperature and salinity vertical profile (1970–2025) and mooring time series (1999–2025) data for structure, trends, and variability at northern Gulf of Alaska coastal oceanographic station GAK1 (59° 50.7′N, 149° 28.0′W). The whole water column (0–250 m) is warming, though marginally faster at the surface (+0.21 ± 0.05°C decade−1 ...

A Genomic Tool to Tackle Cryptic Diversity Demonstrates the Potential for Off‐Target Use of GT‐Seq Panels

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT A comprehensive understanding of life history is vital to successful species conservation and management. When different life history stages are accompanied by considerable morphological or cryptic variation, such as the egg and larval phases exhibited by most fishes, genomic tools are essential for identifying species so that early‐life ...
