Demography of Northern Spotted Owls in southwestern Oregon Demography of Northern Spotted Owls in southwestern Oregon
Northern Spotted Owls (Strix occidentalis caurina) are associated with lower elevation, commercially valuable, late-successional coniferous forests in the Pacific Northwest. Meta-analyses of demographic parameters indicate that Northern Spotted Owl populations are declining throughout their range (Anderson and Burnham 1992, Burnham et al. this volume). Recent research has attempted to...

Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values
As in mammals and fish, birds respond to many environmental contaminants with induction of hepatic cytochromes P450. In order to monitor cytchromes P450 in specific avian species, for assessing the status of that species or the habitat it utilizes, it is necessary to have background information on the appropriate assay conditions and the responsiveness of cytochrome P450 induction in...

Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela
The rain forest of the Sierra Imataca in eastern Venezuela has been subjected to extensive deforestation for pastures and agricultural settlements. In the last decade the opening of access roads combined with intensified logging and mining activities have fragmented a significant portion of the remaining forest. We noted local distribution and habitat use for 42 species of diurnal...
