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 ...

Diet disparity among sympatric herbivorous cichlids in the same ecomorphs in Lake Tanganyika: amplicon pyrosequences on algal farms and stomach contents

BMC Biology, 2014
BackgroundLake Tanganyika, an ancient lake in the Great Rift Valley, is famous for the adaptive radiation of cichlids. Five tribes of the Cichlidae family have acquired herbivory, with five ecomorphs: grazers, browsers, scrapers, biters and scoopers ...

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.

Phenotypic integration of brain size and head morphology in Lake Tanganyika Cichlids

BMC Evolutionary Biology, 2014
BackgroundPhenotypic integration among different anatomical parts of the head is a common phenomenon across vertebrates. Interestingly, despite centuries of research into the factors that contribute to the existing variation in brain size among ...

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.

Distribution and abundance of cichlids in the New Calabar River, Nigeria

Journal of Fisheries, 2018
This study was conducted to study the distribution, abundance and diversity of the cichlids in the New Calabar River, Nigeria. A total of 1073 cichlids belonging to ten species and seven genera (Coptodon guineensis, C. zillii, C.

Multiple Episodic Evolution Events in V1R Receptor Genes of East-African Cichlids

Genome Biology and Evolution, 2014
Fish use olfaction to detect a variety of nonvolatile chemical signals, and thus, this sense is key to survival and communication. However, the contribution of the olfactory sense to social—especially reproductive—interactions in cichlids is still ...

Morphological diversity of the genus Telmatochromis from the Lake Tanganyika drainage with the description of a new riverine species and the generic reassignment of the Malagarasi River lamprologine

Journal of Fish Biology, EarlyView.
Abstract The lamprologine cichlid genus Telmatochromis was long considered primarily lacustrine and endemic to Lake Tanganyika until an undescribed Telmatochromis species was reported from the Lufubu River (Lake Tanganyika drainage, Zambia). A phylogenomic study in 2021 confirmed the association of Telmatochromis sp.
