Data from: Evolution of body shape in differently colored sympatric congeners and allopatric populations of Lake Malawi’s rock-dwelling cichlids

Martin Husemann, Michael Tobler, Cagney McCauley, Baoqing Ding & Patrick D. Danley
The cichlid fishes of Lake Malawi represent one of the most diverse adaptive radiations of vertebrates known. Among the rock-dwelling cichlids (mbuna), closely related sympatric congeners possess similar trophic morphologies (i.e. cranial and jaw structures), defend overlapping or adjacent territories, but can be easily distinguished based on male nuptial coloration. The apparent morphological similarity of congeners, however, leads to an ecological conundrum: theory predicts that ecological competition should lead to competitive exclusion. Hence, we hypothesized...

Data from: Biomechanical and leaf-climate relationships: a comparison of ferns and seed plants

Premise of the study: Relationships of leaf size and shape (physiognomy) with climate have been well characterized for woody non-monocotyledonous angiosperms (dicots), allowing the development of models for estimating paleoclimate from fossil leaves. More recently, petiole width of seed plants has been shown to scale closely with leaf mass. By measuring petiole width and leaf area in fossils, leaf mass per area (MA) can be estimated and an approximate leaf life span inferred. However, little...

Data from: \"Transcriptomic resources for three populations of Conus miliaris (Mollusca: Conidae) from Easter Island, American Samoa and Guam\" in Genomic Resources Notes Accepted 1 August 2014-30 September 2014

Species interactions represent fundamental ecological processes that can have significant impacts on the evolutionary trajectories of species. However, the contribution of predator-prey interactions to genetic and phenotypic divergence within and between species remains largely unknown. In this context, predatory marine snails of the genus Conus exhibit considerable variation in venom composition, a phenomenon that may be due to the evolution of conotoxins in response to predator-prey interactions. It has been hypothesized that geographic differences in...

Drosophila (Drosophila) nigrosparsa is a habitat specialist restricted to the European montane/alpine zone (Bächli 2008). Mountain biodiversity is considered highly vulnerable to ongoing climate warming (IPCC 2013), and organisms at high altitudes have only limited possibility to shift to cooler habitats at elevations above (Pertoldi & Bach 2007). For such species, rapid evolution may offer a solution for long-term survival. We are establishing D. nigrosparsa as a model system to test the extent and tempo...

Data from: Quantitative genetic analyses of male color pattern and female mate choice in a pair of cichlid fishes of Lake Malawi, East Africa

Baoqing Ding, Daniel W. Daugherty, Martin Husemann, Ming Chen, Aimee E. Howe & Patrick D. Danley
The traits involved in sexual selection, such as male secondary sexual characteristics and female mate choice, often co-evolve which can promote population differentiation. However, the genetic architecture of these phenotypes can influence their evolvability and thereby affect the divergence of species. The extraordinary diversity of East African cichlid fishes is often attributed to strong sexual selection and thus this system provides an excellent model to test predictions regarding the genetic architecture of sexually selected traits...
