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
