Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

open access: yesJournal of Fish Biology, Volume 109, Issue 1, Page 588-593, July 2026.
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

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
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

Assemblage structure of ichthyoplankton in the NE Atlantic in spring under contrasting hydrographic conditions

open access: yesScientific Reports, 2019
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

open access: yesMarine Biology Research, 2015
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.

Development and Assessment of Fluorescent‐Dyed, Preserved Invasive Grass Carp (Ctenopharyngodon idella) Eggs as Surrogates for Live Eggs in Transport and Dispersal Control Experiments

open access: yesRiver Research and Applications, Volume 42, Issue 5, Page 976-988, June 2026.
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

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
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

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
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

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.
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.

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
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

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
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.
