Dynamics of Growth–Feeding Mechanisms in Japanese Anchovy Larvae Under Different Environmental Conditions

Fisheries Oceanography, EarlyView.
ABSTRACT The linkage between growth rate and feeding success in fish larvae has received much attention as a potential indicator of future growth and survival potential. Given the increasing evidence that the growth–survival relationship is highly variable, the growth–feeding linkage would also exhibit variable dynamics among cohorts of the same ...

Mesoscale Oceanographic Processes Drive the Seasonal Abundance of the Seabob Shrimp Xiphopenaeus spp. on the Eastern Brazilian Shelf

Fisheries Oceanography, EarlyView.
ABSTRACT The seabob shrimp (Xiphopenaeus spp.) is a primary fishery resource in Brazil, with considerable economic and social importance along the coast. While environmental drivers of its life cycle are well‐documented for southeastern and southern populations, the factors modulating populations in the Eastern Brazilian Shelf remain poorly understood,

Variation in Thermal Tolerance and Its Relationship to Mitochondrial Function Across Populations of Tigriopus californicus

Frontiers in Physiology, 2019
Variation in thermal tolerance plays a key role in determining the biogeographic distribution of organisms. Consequently, identifying the mechanistic basis for thermal tolerance is necessary for understanding not only current species range limits but ...

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Bioaccumulation of methylmercury in a marine copepod

Environmental Toxicology and Chemistry, 2016
Abstract   Methylmercury (MeHg) is known to biomagnify in marine food chains, resulting in higher concentrations in upper trophic level animals than their prey. To better understand how marine copepods, an important intermediate between phytoplankton and forage fish at the bottom of the food chain ...

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution

Journal of Fish Biology, EarlyView.
Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

Journal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

Assessing local adaptation and divergence at early life stages within Eastern Baltic cod (Gadus morhua)

Journal of Fish Biology, EarlyView.
Abstract Many commercially exploited fish stocks have declined over the last few decades. It is therefore essential to identify natural populations and understand local adaptation for sustainable management. Salinity is a key environmental factor shaping local adaptation, and adaptive trait divergence often occurs at the egg and larval stages.

Introduction to trophology of walleye pollock

Известия ТИНРО, 2015
Various aspects of walleye pollock feeding at different stages of its ontogenesis are reviewed and discussed. Structure and functional features of its mouth organs are considered with meristic and quantitative description of the filter one.
