ECOLOGY OF MENIDIA MENIDIA LARVAE IN TWO TEMPERATE ESTUARINE LITTORAL HABITATS

open access: gold, 2020
The Atlantic silverside (Menidia menidia) is one of the numerically most abundant fish species in estuaries along the East Coast of North America, but its ecology during the first two weeks post-hatch has not been described. Therefore ecological investigations into appropriate sampling methods, preferred habitats, feeding ecology and growth of these ...

Conservation Units for Anadromous Arctic Char (<i>Salvelinus alpinus</i>) in the Canadian Arctic Informed by Genetic Structure, Population Connectivity and Adaptive Genomic Variation. [PDF]

open access: yesEvol Appl
ABSTRACT Intraspecific genetic diversity is a crucial aspect of biodiversity conservation as it preserves evolutionary potential and enhances resilience to environmental change. Genomic‐informed delineation of Conservation Units (CUs) offers ways of subdividing species into groups based on demographic independence and adaptive differentiation, to ...

Does tidal marsh restoration lead to the recovery of trophic pathways that support estuarine fishes? [PDF]

open access: yesEcol Appl
Abstract Evaluation of tidal marsh restoration success is typically based on the recovery of habitat size and target species. However, food‐web structure may provide valuable insight into ecosystem functioning trajectories. Here, we studied restored tidal marshes of different ages (new, young, old; spanning 1–150 years) in comparison with nearby ...

High levels of docosahexaenoic acid are present in eight New World silversides (Pisces: Atherinopsidae) [PDF]

open access: yesNeotropical Ichthyology, 2020
Docosahexaenoic acid (DHA) is the most critical and least available omega-3 fatty acid in the Western human diet. Currently, the source of omega-3 long chain polyunsaturated fatty acids (LC-PUFA) is mainly dependent on wild fisheries, making this ...

Contemporary Evolution of an At-Risk Stickleback Population During a Severe Drought. [PDF]

open access: yesEvol Appl
ABSTRACT Populations can be granted conservation status because they harbour a set of unique traits, evolutionary histories, or ecological roles. Such populations are often isolated and specialised and, as such, can be particularly vulnerable to environmental disturbances.

The mitogenome of the California grunion (Leuresthes tenuis)

open access: yesMitochondrial DNA. Part B. Resources, 2020
We report the complete mitogenome for the California grunion (Leuresthes tenuis), a beach-spawning silverside fish endemic to eastern Pacific coastal waters of California, USA and Baja California, Mexico.

Retention of elements absorbed by juvenile fish (Menidia menidia, Menidia beryllina) from zooplankton prey [PDF]

open access: yesLimnology and Oceanography, 1994
Radiolabeled copepods (Acartia spp.) were fed to juvenile silversides (Menidia menidia and Menidia beryllina) to study clement absorption in the fish. Copepods were reared from nauplii in the presence of different radiotracers (14C,109Cd, 57Co, 32P,35S,75Se, or 65Zn) and were analyzed for relative concentrations of these elements in their tissue ...

Variable susceptibility and response to estrogenic chemicals in Menidia menidia [PDF]

open access: yesMarine Ecology Progress Series, 2009
Environmental endocrine disruptors can profoundly impact sex ratios of fish popula- tions, especially if the fish exhibits plasticity in sex determination. The Atlantic silverside Menidia menidia exhibits a genetically based latitudinal cline in numerous traits including temperature- dependent sex determination (TSD), which varies from high thermal ...

Are long-term growth responses to elevated pCO2 sex-specific in fish?

open access: yesPLoS ONE, 2020
Whether marine fish will grow differently in future high pCO2 environments remains surprisingly uncertain. Long-term and whole-life cycle effects are particularly unknown, because such experiments are logistically challenging, space demanding, exclude ...

Transcriptional flexibility during thermal challenge corresponds with expanded thermal tolerance in an invasive compared to native fish

open access: yesEvolutionary Applications, 2021
Capacity to cope with warming temperatures is a key determining factor of species' persistence under global climate change. Many successful invasive species have heightened thermal tolerance relative to their native counterparts, which may provide ...
