Cytoarchitecture of a Cichlid Fish Telencephalon [PDF]
Brain, Behavior and Evolution, 2009 Although the telencephalon of ray-finned fishes has garnered considerable attention from comparative neuroanatomists, detailed descriptions of telencephalic organization are available for only a few species. This necessarily limits our understanding of telencephalic evolution, particularly in light of the extraordinary diversity of ray-finned fishes ...

Hybridisation generates a hopeful monster: a hermaphroditic selfing cichlid [PDF]
, 2016 Compared to other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes.

Gene duplication in an African cichlid adaptive radiation [PDF]
, 2014 Background Gene duplication is a source of evolutionary innovation and can contribute to the divergence of lineages; however, the relative importance of this process remains to be determined.

Nile tilapia skin xenograft versus silver-based hydrofiber dressing in the treatment of second-degree burns in adults [PDF]
Revista Brasileira de Cirurgia Plástica, 2019 Introduction: Recent studies have suggested the use of biological dressings made of aquatic animals as biomaterials in regenerative medicine since they demonstrate good adherence to the wound bed.

Strong biomechanical relationships bias the tempo and mode of morphological evolution
eLife, 2018 The influence of biomechanics on the tempo and mode of morphological evolution is unresolved, yet is fundamental to organismal diversification. Across multiple four-bar linkage systems in animals, we discovered that rapid morphological evolution (tempo ...

Tit for Tat in the Dear Enemy Relationship Between Territorial Females of a Cichlid Fish
Frontiers in Ecology and Evolution, 2018 Many territorial animals reduce aggression toward their neighbors once territorial boundaries are established. This relationship is called the dear enemy phenomenon, hypothetically based on a conditional strategy like tit for tat (TFT).

Hybrid Breakdown in Cichlid Fish
PLOS ONE, 2015 Studies from a wide diversity of taxa have shown a negative relationship between genetic compatibility and the divergence time of hybridizing genomes. Theory predicts the main breakdown of fitness to happen after the F1 hybrid generation, when heterosis subsides and recessive allelic (Dobzhansky-Muller) incompatibilities are increasingly unmasked.

Cuadernos de investigación UNED, 2015 Disease is an important factor in fisheries, affecting both wild and cultured species. Using standard parasitological techniques we determined the prevalence, mean intensity and abundance of endoparasites from 250 specimens of two cichlids, Oreochromis ...
