A single gene that regulates testosterone levels in a "crazy" species of shore bird controls the development of three wildly different types of males, an international study involving researchers at ...

The ruff is a Eurasian shorebird that has a spectacular lekking behavior where highly ornamented males compete for females. Now two groups report that males with alternative reproductive strategies ...

Figure 1: Comparison of independent, satellite and faeder ruff males. Figure 2: Genetic mapping and genome-wide association analysis identify the genomic region determining ruff reproductive morphs.

Mechanisms underlying habitat use in most species are poorly understood. Therefore, we integrated behavioral and forest cover type data to test hypotheses underlying the choice of two key cover types ...
