Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, EarlyView.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

SEXUAL SPECIES ARE SEPARATED BY LARGER GENETIC GAPS THAN ASEXUAL SPECIES IN ROTIFERS

Evolution; international journal of organic evolution, 2014
Why organisms diversify into discrete species instead of showing a continuum of genotypic and phenotypic forms is an important yet rarely studied question in speciation biology.

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Predator species of fish play crucial roles in ecosystem balance through top‐down control, a mechanism frequently exploited in biomanipulation to stock predator species. Juvenile pikeperch (Sander lucioperca) were stocked (n = 52,887) in spring 2023 and 2024 and autumn 2023 to compare stocking efficiency between Recirculation Aquaculture ...

Manipulation of the fatty acid composition of phosphatidylcholine and phosphatidylethanolamine in rotifers Brachionus Nevada and Brachionus Cayman

, 2015
Rotifer cultures of Brachionus Nevada and Cayman were grown semi-continuously, fed live Rhodmonas baltica algae, and cultures were diluted daily (20% day−1). The enrichment diets Marol E (triacylglycerol-rich) and PL (cod roe emulsion, phospholipid-rich)

Orientation and Swimming Behavior of Saithe (Pollachius virens) Larvae Increases the Chance of Recruitment to Nursery Areas

Fisheries Oceanography, EarlyView.
ABSTRACT Saithe (Pollachius virens) is a semipelagic North Atlantic species supporting an important fishery. In the North Sea, saithe spawn east of the Shetland Islands, with larvae recruiting to coastal areas. Understanding the interaction between abiotic and biotic factors influencing larval dispersal is crucial for assessing their population ...
