摘要: Abstract Proper management of grasslands and shrublands requires an understanding the factors that influence persistence organisms. We compare differences in vegetation between sites occupied by lesser prairie-chicken (Tympanuchus pallidicinctus) random to investigate composition grasses forbs importance cover. observed birds selected habitat, at least part, based on forbs. There was generally a larger variance diversity plants for compared associated with presence prairie-chicken. The role vegetative cover selection habitat is important avoidance predators, but use also means thermoregulation. Risk-sensitive behavior trade-off avoiding predation suitable microclimate. report evidence consistently seeks limit risk selects locales favorable microclimate; select mor...
