Assessing habitat suitability for black grouse broods at the bioregional scale
Wildlife Biology, EarlyView.The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)
Journal of Anatomy, EarlyView.Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Journal of Anatomy, EarlyView.Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...
