Journal of Animal Ecology, EarlyView.This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Interspecific hybridization can generate functional novelty in cichlid fish
Proceedings of the Royal Society B, 2019 The role of interspecific hybridization in evolution is still being debated. Interspecific hybridization has been suggested to facilitate the evolution of ecological novelty, and hence the invasion of new niches and adaptive radiation when ecological ...

Molecular biology and evolution, 2020 The two toothed jaws of cichlid fishes provide textbook examples of convergent evolution. Tooth phenotypes such as enlarged molar-like teeth used to process hard-shelled molluscs have evolved numerous times independently during cichlid diversification ...

Integrative Zoology, EarlyView.In this study, we tested whether white and yellow morphs of the common wall lizard (Podarcis muralis) adopt alternative strategies shaped by the immuno‐competence handicap hypotheses (ICHH). We found that testosterone‐induced immune suppression was stronger in white males, while aggression decreased in both morphs.

Systematic Biology, 2020 The Midas cichlids of the Amphilophus citrinellus spp. species complex from Nicaragua (13 species) are an extraordinary example of adaptive and rapid radiation (< 24,000 years old).

Integrative Zoology, EarlyView.Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

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.

Land Cover, Land Use, and Climate Change Impacts on Endemic Cichlid Habitats in Northern Tanzania
Remote Sensing, 2017 Freshwater ecosystems are among the most threatened on Earth, facing environmental and anthropogenic pressures often surpassing their terrestrial counterparts. Land use and land cover change (LUCC) such as degradation and fragmentation of the terrestrial
