Sex‐biased dispersal in the Arabian babbler (Argya squamiceps)
Ibis, Volume 168, Issue 2, Page 604-615, April 2026.Sex‐biased dispersal plays a central role in shaping social structure and reproductive strategies in many bird species. In the Arabian Babbler Argya squamiceps, a cooperatively breeding species with pronounced male philopatry, dispersal occurs individually or in kin‐based same‐sex coalitions.

Unprotected Waters: When Protection Fails In Freshwater
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.ABSTRACT Invasive species are a major driver of biodiversity loss in protected areas (PAs), yet their impacts in aquatic environments are less well documented. This study investigated the occurrence and distribution of nonnative freshwater fish in federal PAs in Brazil.

Carotenoid-based coloration in cichlid fishes
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2014 Animal colors play important roles in communication, ecological interactions and speciation. Carotenoid pigments are responsible for many yellow, orange and red hues in animals. Whereas extensive knowledge on the proximate mechanisms underlying carotenoid coloration in birds has led to testable hypotheses on avian color evolution and signaling, much ...

Ecology and Evolution, Volume 16, Issue 3, March 2026.Kaptai Lake is a developing ecosystem with a linear food web and thereby vulnerable to external influences. The apex predator, Catfish (TL‐3.364), occupied the top trophic niches, while the overabundant (B: 3.264 t/km2) Clupeid (TL‐2.56) dominated the lower trophic level in the food web. The higher values of ecotrophic efficiency for most of the groups

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...

Long‐read sequencing for biodiversity analyses—A comprehensive guide
Methods in Ecology and Evolution, Volume 17, Issue 3, Page 650-667, March 2026.Abstract DNA‐based monitoring of biodiversity has revolutionised our ability to describe communities and rapidly assess anthropogenic impacts on biodiversity. Currently established molecular methods for biomonitoring rely heavily on classic metabarcoding utilising short reads, mostly through Illumina data.
