The Colorado Plateau: cultural, biological, and physical research The Colorado Plateau: cultural, biological, and physical research
Stretching from the four corners of Arizona, New Mexico, Colorado, and Utah, the Colorado Plateau is a natural laboratory for a wide range of studies. This volume presents 23 original articles drawn from more than 100 research projects presented at the Sixth Biennial Conference of Research on the Colorado Plateau. This scientific gathering revolved around research, inventory, and...

Teetering on the edge or too late? Conservation and research issues for avifauna of sagebrush habitats Teetering on the edge or too late? Conservation and research issues for avifauna of sagebrush habitats
Degradation, fragmentation, and loss of native sagebrush (Artemisia spp.) landscapes have imperiled these habitats and their associated avifauna. Historically, this vast piece of the Western landscape has been undervalued: even though more than 70% of all remaining sagebrush habitat in the United States is publicly owned,

Epizootiology and effect of avian pox on Hawaiian forest birds Epizootiology and effect of avian pox on Hawaiian forest birds
We determined prevalence and altitudinal distribution of forest birds infected with avian pox at 16 locations on Hawaii, from sea level to tree line in mesic and xeric habitats, during 1977–1980. Isolates from lesions were cultured in the laboratory for positive identification of Poxvirus avium. Infected birds from the wild were brought into the laboratory to assess differences in the...

`Akohekohe response to flower availability: seasonal abundance, foraging, breeding, and molt `Akohekohe response to flower availability: seasonal abundance, foraging, breeding, and molt
We studied the relationship of flower availability to the seasonality of life history events of the `Akohekohe (Palmeria dolei), a primarily nectarivorous and endangered Hawaiian honeycreeper from montane rain forests on Maui, Hawai`i. For comparison, we also investigated temporal bird density and foraging behavior of three other competing Hawaiian honeycreepers: `Apapane (Himatione...
