Molecular biomarkers and toxic consequences of impact by organic pollution in aquatic organisms [PDF]

open access: yes, 1994
Organic contaminants are readily bioaccumulated by aquatic organisms. Exposure to and toxic effects of contaminants can be measured in terms of the biochemical responses of the organisms (i.e. molecular biomarkers).

Local Adaptation and Osmoregulatory Mechanisms of the Copepod Acartia tonsa Under Low Salinity Stress

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Salinity—an essential factor shaping marine species distributions—is rapidly shifting due to global change, yet the mechanisms of salinity tolerance and adaptation remain poorly understood. We investigated local adaptation in the calanoid copepod Acartia tonsa, a broadly distributed marine species that thrives in the brackish Baltic Sea. Using

Summer Diet of Humpback Whales in the Northern Strait of Georgia, British Columbia (Canada), Revealed by Stable Isotope Analysis

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT North Pacific humpback whales (Megaptera novaeangliae) have recovered rapidly following their depletion by commercial whaling. Diet studies are necessary to assess food web implications of their recovery. This study investigates the diet composition of humpback whales foraging in the northern Strait of Georgia, British Columbia, Canada, an ...

Relación biogeográfica entre cangrejos dulceacuícolas y acociles a lo largo de la zona mexicana de transición: revaluación de la hipótesis de Rodríguez (1986) Biogeographic relationship of freshwater crabs and crayfish along the Mexican transition zone: reevaluating Rodríguez (1986) hypothesis

open access: yesRevista Mexicana de Biodiversidad, 2012
A partir de la hipótesis planteada por Rodríguez (1986) sobre una posible exclusión biogeográfica entre acociles de la familia Cambaridae y cangrejos de agua dulce de la familia Pseudothelphusidae a lo largo del centro y sur de México, se han hecho ...

Stress Nutrition in Aquatic Animals: From Definition to Practice

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
