- DOI：
- doi:10.5061/dryad.6b578
- 摘要：
- patterns of selection acting on ornaments and weapons in the wild. Here, we measure selection on a wild population of weapon-bearing beetles (frog legged
Data from: Novel host plant leads to the loss of sexual dimorphism in a sexually-selected male weapon

- doi:10.5061/dryad.5p19k
- 摘要：
- -selected weapons and ornaments frequently influence fitness and often have heightened condition-dependence in response to nutrition. Condition-dependence
Data from: Enhanced male coloration after immune challenge increases reproductive potential

- 摘要：
- ornaments are reliable indicators of immunocompetence, because the cost of immune function prevents cheating. However, sexual signalling is a component
Data from: MHC variation is related to a sexually selected ornament, survival and parasite resistance in common yellowthroats

- doi:10.5061/dryad.cn72p
- 摘要：
- Hamilton and Zuk (1982) proposed that females choose mates based on ornaments whose expression is dependent on their genetically based resistance

- 摘要：
- Avian plumage colours are some of the most conspicuous sexual ornaments, and yet standardized selection gradients for plumage colour have rarely
Data from: Limits to environmental masking of genetic quality in sexual signals
- 负责人：
- DOI：
- doi:10.5061/dryad.6p150kf
- 摘要：
- There is considerable debate over the value of male sexual ornaments as signals of genetic quality. Studies alternately report tha
Data from: The size of a melanin-based plumage ornament correlates with glucocorticoid receptor concentrations in the skin of that ornament

- of CORT receptors in the skin of melanized ornaments. Male house sparrows (Passer domesticus) have a black, melanized bib, and evidence suggests that bib
