Assessing Biodiversity at Eastern Oyster (<i>Crassostrea virginica</i>) Aquaculture and Reef Sites Utilizing Real-Time Monitoring and Environmental DNA in Rehoboth Bay, Delaware, USA. [PDF]

Ecol Evol
Eastern Oysters (Crassostrea virginica) are a keystone species and an important product of the commercial shellfish industry in Delaware. Oysters are known as “environmental engineers” that provide a structured habitat for the ecosystem, thus promoting ...

Infection of Atlantic tripletail Lobotes surinamensis (Teleostei: Lobotidae) by brain metacercariae Cardiocephaloides medioconiger (Digenea: Strigeidae). [PDF]

PeerJ, 2023
Three juvenile Atlantic tripletail Lobotes surinamensis caught opportunistically in Charleston Harbor (South Carolina, USA) and maintained in captivity for over three months displayed an altered swimming behavior.

Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs. [PDF]

Environ Microbiol Rep
Here we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...

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]

Evol 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 Reproductive Investment Decrease Telomere Length in Menidia menidia?

PLOS ONE, 2015
Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that telomere maintenance may trade off against other life history characters. We used natural variation

NONLINEAR GROWTH COST IN MENIDIA MENIDIA: THEORY AND EMPIRICAL EVIDENCE [PDF]

Evolution; International Journal of Organic Evolution, 2004
Juvenile growth is submaximal in many species, suggesting that a trade-off with juvenile growth must exist. In support of this, recent studies have demonstrated that rapid growth early in life results in decreased physiological performance. Theory clearly shows that for submaximal growth in juveniles to be optimal, the cost of growth must be nonlinear.

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

Ecol 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 connectivity among locally adapted populations of a marine fish (Menidia menidia) [PDF]

Ecology, 2010
Patterns of connectivity are important in understanding the geographic scale of local adaptation in marine populations. While natural selection can lead to local adaptation, high connectivity can diminish the potential for such adaptation to occur. Connectivity, defined as the exchange of individuals among subpopulations, is presumed to be significant ...

Sex-Linked Differentiation in Commercially Exploited Fishes: Rethinking Population Structure in Dynamic Marine Environments. [PDF]

Glob Chang Biol
Sex‐linked divergence, rather than geography, is the principal driver of genomic variation in the commercially important deep‐water hake (Merluccius paradoxus) located off the southern African coastline. Together with spatial differences in sex distribution and genomic diversity metrics, results suggest that males and females may differ in both range ...

Behavioral and molecular effects of micro and nanoplastics across three plastic types in fish: weathered microfibers induce a similar response to nanosized particles. [PDF]

Front Toxicol
Micro and nanoplastics (MNPs) are ubiquitous in the environment and have been detected in most ecosystems, including remote regions. The class of contaminants under the MNP umbrella is quite broad and encompasses variable polymer types, shapes, and sizes.
