Introgression and Divergence in a Young Species Group

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The process of speciation concerns often multiple diverging and interacting taxa, not only taxon pairs. Understanding the evolution of species' diversity and their persistence therefore requires insight into how gene flow and evolution of reproductive isolation shape groups of closely related species.

Father Convict Cichlids Bite Intruders More Often in Hot Temperatures

, 2015
Convict cichlids (Archocentrus nigrofasciatus) have evolved to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate predators.

Infectious Diseases Management in Small‐Scale Freshwater Aquaculture in West Africa: Lessons for Low‐ and Middle‐Income Countries

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.

Predator avoidance in extremophile fish

, 2013
Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P ...

A pharyngeal jaw evolutionary innovation facilitated extinction in Lake Victoria cichlids

, 2015
Evolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction.

Experimentally induced helper dispersal in colonially breeding cooperative cichlids [PDF]

, 2018
The ‘benefits of philopatry' hypothesis states that helpers in cooperatively breeding species derive higher benefits from remaining home, instead of dispersing and attempting to breed independently.

Molecular Evolution of Dim-light Visual Pigments in Neotropical Geophagine Cichlids

, 2013
Neotropical cichlid fishes are highly diverse and occupy diverse environments. Visual pigment evolution has been important in the diversification of African rift lake cichlids, but little is known of Neotropical cichlid visual systems.

Cichlids of the lower Congo River - a new model system in speciation research? [PDF]

, 2012
Fishes account for the highest diversity of all vertebrate groups on our planet. Among them one group clearly outnumbers all the others - cichlids (Perciformes, Cichlidae).
