Testing the performance of environmental DNA metabarcoding for surveying highly diverse tropical fish communities: A case study from Lake Tanganyika

Environmental DNA, 2020
Background and Aims Environmental DNA (eDNA) metabarcoding provides a highly sensitive method of surveying freshwater fish communities, although studies to date have largely been restricted to temperate ecosystems.

Unusual Diversity of Sex Chromosomes in African Cichlid Fishes

Genes, 2018
African cichlids display a remarkable assortment of jaw morphologies, pigmentation patterns, and mating behaviors. In addition to this previously documented diversity, recent studies have documented a rich diversity of sex chromosomes within these fishes.

Climate‐Mediated Hybridisation and the Future of Andean Forests

Journal of Biogeography, EarlyView.
ABSTRACT The tropical Andes face unprecedented warming and shifting precipitation patterns due to climate change and land‐use alteration, challenging the future of Andean forests. During the Quaternary, many Andean trees responded to climate change through upslope migrations but, while there is evidence of such ongoing migrations in many species, they ...

Evolutionary divergence of novel open reading frames in cichlids speciation

Scientific Reports, 2020
Novel open reading frames (nORFs) with coding potential may arise from noncoding DNA. Not much is known about their emergence, functional role, fixation in a population or contribution to adaptive radiation.

Molecular mechanisms underlying nuchal hump formation in dolphin cichlid, Cyrtocara moorii

Scientific Reports, 2019
East African cichlid fishes represent a model to tackle adaptive changes and their connection to rapid speciation and ecological distinction. In comparison to bony craniofacial tissues, adaptive morphogenesis of soft tissues has been rarely addressed ...

Coercive mating has no impact on spatial learning, cognitive flexibility, and fecundity in female porthole livebearers (Poeciliopsis gracilis)

Journal of Fish Biology, EarlyView.
Abstract Coercive mating is a sexual selection strategy that is likely to influence female cognition. Female harassment levels have been linked to altered brain gene expression patterns and brain size evolution, suggesting females may respond to coercive mating by investing energy into “outsmarting” males.

Lessons from a natural experiment: Allopatric morphological divergence and sympatric diversification in the Midas cichlid species complex are largely influenced by ecology in a deterministic way

Evolution Letters, 2018
Explaining why some lineages diversify while others do not and how are key objectives in evolutionary biology. Young radiations of closely related species derived from the same source population provide an excellent opportunity to disentangle the ...

Two new species of Mylochromis (Cichlidae) from Lake Malawi, Africa

Journal of Fish Biology, EarlyView.
Abstract Two new species of Mylochromis Regan 1920 are described from specimens collected on shallow rocky habitats on the northwestern coast of Lake Malawi. The generic designation is based on their prominent oblique‐striped pattern and lack of any of the unique features of other Malawi cichlid genera with this pattern. Mylochromis rotundus sp.

Agouti-related peptide 2 facilitates convergent evolution of stripe patterns across cichlid fish radiations

Science, 2018
Showing their stripes The adaptive radiation of East African cichlids has led to more than 1200 species across a number of lakes. Across these species, many convergent traits have emerged, including the presence or absence of horizontal stripes ...
