Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

The ichthyoplankton assemblage in the Atlantic region off the NW Iberian peninsula (AR) and in the southern Bay of Biscay (SBB) and the response of the larval fish species distribution to the relatively rapidly changing hydrographic conditions in spring ...

Ichthyoplankton dynamics in a highly urbanized estuary
AbstractSpatio-temporal distribution and composition of ichthyoplankton assemblages were studied in the Golden Horn estuary (Istanbul) over a 10-month period. Environmental parameters were considered to determine the environmental status in different parts (upper, middle and lower) of the estuary.

ABSTRACT Invasive species such as grass carp ( Ctenopharyngodon idella ) pose substantial ecological threats to North American freshwater ecosystems. Understanding their early life stage behavior is critical for management efforts. From spawning to hatching, invasive carp eggs must remain suspended in the water column while drifting downstream for the ...

Biological characterization of a mid‐water salinity maximum intrusion over the Northeast US Shelf
Abstract Salinity maximum intrusions, subsurface layers of anomalously salty and warm continental slope water moving onto the continental shelf along the thermocline, are recurring features over the Northeast US Shelf and represent an important cross‐shelf exchange mechanism.

Temporal dynamics of mesopelagic fishes within a mesoscale eddy: A Lagrangian perspective
Abstract Mesoscale eddies are physically dynamic environments, yet biological responses within them are often treated as static, with eddy polarity (anticyclones vs. cyclones) serving as the dominant conceptual framework. Temporal dynamics of animals within eddies—particularly at mid‐trophic levels—remain largely unresolved.

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

Genetic Structure of Blue Ling, Molva dypterygia, in the North Atlantic
The blue ling, a deep‐water fish in the Northeast Atlantic, has experienced severe population declines since the 1970s due to intensive fishing. Genetic analysis across fjords and offshore regions using 61 SNPs revealed weak but significant differentiation, rejecting the idea of a single randomly mating population.
