Environmental Toxicology, EarlyView.ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Journal of Animal Ecology, EarlyView.Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Integrative Zoology, EarlyView.We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Swimming performance of Cyprinus carpio (Carp) in China
Heliyon, 2023 Cyprinus carpio (Carp) is a fish of great economic importance in China. However, its population has declined considerably due to the construction of barrages. Thus, fishways need to be constructed at barrages to protect fish resources. It is essential for the fishway design to study the swimming performance of carp.

Integrative Zoology, EarlyView.High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.
