Integrative Zoology, EarlyView.Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Hearing in the jewel cichlid [PDF]
The Journal of the Acoustical Society of America, 1982 An in-depth analysis of hearing sensitivity for the jewel cichlid, Hemichromis bimaculatus was made using neurophysiological techniques to measure sensitivity at various levels of the auditory system and psychophysical techniques to measure whole-system sensitivity. For physiological studies, fish were stimulated by sinusoids generated by a loudspeaker

Acta Zoologica, EarlyView.ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.

Evolution: Cichlid Models on the Runaway to Speciation [PDF]
Current Biology, 2012 Rapid speciation has fascinated biologists for a long time. A recent study shows that ecological opportunity and sex-biased color differences increase the likelihood of speciation in African cichlid fishes.

Cladistics, EarlyView.Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Rapid generation of ecologically relevant behavioral novelty in experimental cichlid hybrids
Ecology and Evolution, 2020 The East African cichlid radiations are characterized by repeated and rapid diversification into many distinct species with different ecological specializations and by a history of hybridization events between nonsister species.
