The distribution of estuarine fish larvae: nutritional condition and co-occurrence with predators and prey [PDF]

open access: yes, 2000
Fish larvae were collected monthly between March and September 1997 in the Mira and Guadiana estuaries (southern Portugal). Hydrological parameters were registered and zooplankton samples were obtained simultaneously. Densities of fish larvae (ind.100 m(-

Patterns of Population Genomic Variation and Evolutionary History of European Hake in the Northeastern Atlantic

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We use for the first time whole‐genome sequencing to explore current and historical patterns of genetic diversity in European hake in the Northeastern Atlantic, focusing on the recently expanded distribution range in the North Sea. Genomic data revealed a complex scenario with three populations: North Sea, Celtic Sea and Portugal.

DNA Microarrays for Identifying Fishes [PDF]

open access: yes, 2008
In many cases marine organisms and especially their diverse developmental stages are difficult to identify by morphological characters. DNA-based identification methods offer an analytically powerful addition or even an alternative.

Evaluating Post‐Survey Otolith Subsampling Strategies for a Small‐Bodied, Fast‐Growing Pelagic Fish for Inclusion in Stock Assessments

open access: yesFisheries Management and Ecology, Volume 33, Issue 1, Page 24-39, February 2026.
ABSTRACT Identifying efficient otolith subsampling strategies that maintain data quality for stock assessments is imperative given limited resources to meet age‐estimation demands of managed fish stocks. Our objective was to evaluate the performance of three different subsampling strategies: (1) fixed otolith subsampling, (2) proportional otolith ...

Thermal adaptation and clinal mitochondrial DNA variation of European anchovy [PDF]

open access: yes, 2014
Natural populations of widely distributed organisms often exhibit genetic clinal variation over their geographical ranges. The European anchovy, Engraulis encrasicolus, illustrates this by displaying a two-clade mitochondrial structure clinally arranged ...

The Overlooked Threat of Global Warming on Elasmobranch Fertility

open access: yesFish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

Diffusion and physical constraints limit oxidative capacity, capillary supply and size of muscle fibres in mice and humans

open access: yesExperimental Physiology, Volume 111, Issue 1, Page 212-225, 1 January 2026.
Abstract It has been suggested that angiogenesis during skeletal muscle fibre hypertrophy allows escape from the ‘size constraint’, which is the inverse relationship between oxidative capacity and muscle fibre cross‐sectional area (FCSA). It is, however, not known whether there are any limitations to the combinations of FCSA, oxidative capacity and ...

Occurrence of potential plastic microfibers in mussels and anchovies sold for human consumption: Preliminary results

open access: yesItalian Journal of Food Safety, 2021
There is a global concern over the impact of microplastics on marine species and trophic webs. Microfibers commonly represent the greater portion of microplastics in the aquatic environment, but little is known about fiber uptake and accumulation by ...
