Effects of climate on size structure and functioning of aquatic food webs [PDF]

open access: yes, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

Grandmother Age Effects via Sperm Telomere Length and Egg Telomerase Transcripts

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT The Lansing effect is a transgenerational age effect by which old parents tend to produce less viable descendants. Despite its importance for the evolution of lifespan and parental effects, the transgenerational nature of age effects and the underlying mechanisms are poorly understood.

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

Early Nutritional Programing: Unlocking the Potential of Fish for Sustainable Aquaculture

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
Nutritional programing, which explores the link between early nutritional conditions and their long‐term effects on animals, is a developing field within fish biology. Suboptimal nutritional status during early life is strongly associated with a higher risk of metabolic consequences later in life, including permanent growth retardation, impaired neural
