Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Distribution of Oreochromis niloticus (L.) in the Ugandan waters of Lake Victoria [PDF]
, 1999 The Lake Victoria fish fauna was dominated by cichlids before the establishment of the exotic species Oreochromis niloticus (L.) and Latus niloticus (L.).

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 5, Page 486-497, June 2026.ABSTRACT Across the animal kingdom, social behaviors such as aggression are critical for survival and reproductive success. While there is significant variation in social behaviors within and between species, the genetic mechanisms underlying natural variation in social behaviors are poorly understood.

Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish [PDF]
, 2013 Reduced male aggression towards different phenotypes generating negative frequency-dependent intrasexual selection has been suggested as a mechanism to facilitate the invasion and maintenance of novel phenotypes in a population.

Heterokairic Genes and the Eco‐Evo‐Devo of Timing
Evolution &Development, Volume 28, Issue 2, June 2026.Heterokairic genes as the bridge (Heterokairic Pathways?): Heterokairic genes are heterochronic regulators whose activity is modulated by environmental conditions. External cues (e.g., temperature, nutrition, oxygen, density: yellow box) are sensed (yellow arrows) and converted into endocrine and metabolic signals (purple box and arrow into fish's ...

Preliminary observations on the feeding, habits and reproduction biology of Gymnarchus niloticus from Lake Chad [PDF]
, 1986 The preliminary results obtained from the study of stomach contents of specimens of Gymnarchus niloticus of a size ranging from 56 cm (66 grams) to 152 cm (12.0 kg.) from August to December, 1982 indicate for these sizes an exclusively piscivorous diet ...

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.ABSTRACT Infectious diseases are an increasing threat to food security, small‐scale livelihoods and the sustainability of aquaculture in low‐ and middle‐income countries (LMICs). In sub‐Saharan Africa, aquaculture is expanding rapidly but production systems often remain fragile.

Hypotheses for the Adaptive Maintenance of Phenotypic Polymorphisms
Ecology and Evolution, Volume 16, Issue 5, May 2026.Phenotypic polymorphisms offer easily observable diversity ideal for empirical and theoretical exploration, but developing and comparing hypotheses for the adaptive maintenance of polymorphism can be a challenge. Here, we propose a framework categorizing polymorphisms based on (i) one of five distinct types of maintenance selection and (ii) the context
