Environmental and vital effects on lithium isotopes and trace element ratios in biogenic carbonates: Insights from an estuarine salinity gradient

Journal article Geochimica Et Cosmochimica Acta · August 15, 2026 Isotope and element ratios in the carbonate skeletons of calcifying marine organisms can be used to reconstruct past environments and understand physiological processes occurring before calcification. The Li isotope composition (δ7Li) of biogeni ... Full text Cite

Egg Hatching, Peptide Pheromones, and Endoproteinases in Barnacles.

Journal article International journal of molecular sciences · November 2025 The striped barnacle, Amphibalanus amphitrite, is a simultaneous hermaphrodite crustacean that broods eggs. The eggs are physically and enzymatically cleaned in the mantle by the barnacle to manage biofouling during incubation. There is no physiolog ... Full text Cite

Exploring the Diversity of the Marine Environment for New Anti-cancer Compounds

Journal article Frontiers in Marine Science · January 21, 2021 Marine ecosystems contain over 80% of the world’s biodiversity, and many of these organisms have evolved unique adaptations enabling survival in diverse and challenging environments. The biodiversity within the world’s oceans is a virtually untapped resour ... Full text Cite

Embryonic Fundulus heteroclitus responses to sediment extracts from differentially contaminated sites in the Elizabeth River, VA.

Journal article Ecotoxicology (London, England) · November 2019 Sites along the Elizabeth River are contaminated with polycyclic aromatic hydrocarbons (PAHs) from historical creosote production and other industrial processes. Previous studies have demonstrated that Atlantic killifish collected from sites throughout the ... Full text Cite

Genome-wide scan reveals signatures of selection related to pollution adaptation in non-model estuarine Atlantic killifish (Fundulus heteroclitus).

Journal article Aquatic toxicology (Amsterdam, Netherlands) · July 2018 In many human-altered ecosystems, organisms are increasingly faced with more diverse and complex environmental stressors and pollutant mixtures, to which the adaptations necessary to survive exposure are likely to be numerous and varied. Improving our unde ... Full text Cite

Cost of Tolerance: Physiological Consequences of Evolved Resistance to Inhabit a Polluted Environment in Teleost Fish Fundulus heteroclitus.

Journal article Environmental science & technology · August 2017 Anthropogenic stressors, including pollutants, are key evolutionary drivers. It is hypothesized that rapid evolution to anthropogenic changes may alter fundamental physiological processes (e.g., energy metabolism), compromising an organism's capacity to re ... Full text Cite

Erratum to: Antioxidant Rescue of Selenomethionine-Induced Teratogenesis in Zebrafish Embryos.

Journal article Archives of environmental contamination and toxicology · October 2016 Full text Cite

Antioxidant Rescue of Selenomethionine-Induced Teratogenesis in Zebrafish Embryos.

Journal article Archives of environmental contamination and toxicology · February 2016 Selenium (Se) is an essential micronutrient that can be found at toxic concentrations in surface waters contaminated by runoff from agriculture and coal mining. Zebrafish (Danio rerio) embryos were exposed to aqueous Se in the form of selenate, selenite, a ... Full text Cite

Reducing Environmental Toxicity of Silver Nanoparticles through Shape Control.

Journal article Environmental science & technology · August 2015 The use of antibacterial silver nanomaterials in consumer products ranging from textiles to toys has given rise to concerns over their environmental toxicity. These materials, primarily nanoparticles, have been shown to be toxic to a wide range of organism ... Full text Cite

Acute toxicity and sub-lethal effects of common pesticides in post-larval and juvenile blue crabs, Callinectes sapidus

Journal article Journal of Experimental Marine Biology and Ecology · August 1, 2012 The coastal plains of the southeastern United States support extensive agricultural operations that apply pesticides and herbicides. The shallow tidal creeks and ditches that directly drain agricultural fields are home to the young of the ecologically and ... Full text Cite

The digestive system of the hydrothermal vent polychaete Galapagomystides aristata (Phyllodocidae): Evidence for hematophagy?

Journal article Invertebrate Biology · January 1, 2002 Anatomical, histological, and ultrastructural investigation of the hydrothermal vent phyllodocid Galapagomystides aristata shows that this unusual polychaete has a normal mouth and foregut but a highly modified midgut with a blood-filled lumen. The foregut ... Full text Cite
