Oxidative stress in the brain is regulated by social status in a highly social cichlid fish
Frontiers in Behavioral NeuroscienceSocial stress can increase reactive oxygen species and derail antioxidant function in the brain, which may contribute to the onset and progression of mental health disorders.

Ecology and Evolution, 2023 Phenotypic plasticity enables development to produce multiple phenotypes in response to environmental conditions. Plasticity driven variation has been suggested to play a key role in adaptive divergence, and plasticity itself can evolve.

Chromosome-scale assemblies reveal the structural evolution of African cichlid genomes
bioRxiv, 2018 Background African cichlid fishes are well known for their rapid radiations and are a model system for studying evolutionary processes. Here we compare multiple, high-quality, chromosome-scale genome assemblies to understand the genetic mechanisms ...

Molecular Ecology, 2020 Cichlid fishes' famous diversity in body coloration is accompanied by a highly diverse and complex visual system. Although cichlids possess an unusually high number of seven cone opsin genes, they express only a subset of these during their ontogeny ...

The Anatomical Record, EarlyView.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Analysis of the meiotic segregation in intergeneric hybrids of tilapias [PDF]
, 2012 Tilapia species exhibit a large ecological diversity and an important propensity to interspecific hybridisation. This has been shown in the wild and used in aquaculture.

Game over: Conflict resolution through strategic growth in an invertebrate
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract In some multimember groups with unequal partitioning of reproduction and poor breeding opportunities outside the group, natural selection has favoured the evolution of adaptive mechanisms such as strategic growth modulation.

Frontiers in Endocrinology, 2020 Gonadotropin-releasing hormone (GnRH) is a reproductive neuropeptide, which controls vertebrate reproduction. In most vertebrates, there are more than two GnRH orthologs in the brain.

Introduced predator elicits deficient brood defence behaviour in a crater lake fish. [PDF]
PLoS ONE, 2012 Introduced species represent one of the most serious global threats to biodiversity. In this field-based study, we assessed behavioural responses of brood tending cichlid fish to an invasive predator of their offspring.

The comparative genomic landscape of adaptive radiation in crater lake cichlid fishes
Molecular Ecology, 2020 Factors ranging from ecological opportunity to genome composition might explain why only some lineages form adaptive radiations. While being rare, particular systems can provide natural experiments within an identical ecological setting where species ...
