چکیده
(Squires and Reynolds 1997). The degree to which goshawks migrate during winter may relate to prey a v a i l a b i l i t y. In the Yukon Territory in winter, goshawknumbers fluctuate with snowshoe hare numbers (Doyle and Smith 1994). Some goshawks may travel short distances in winter to lower elevations or more open habitats (Squires and Reynolds 1997), and migrations may consist of predominately immature birds (Sibley 1993).

Are Montane Forests Demographic Sinks for Bornean White-bearded Gibbons Hylobates albibarbis?
I estimated habitat-specific population densities for a population of Bornean white-bearded gibbons Hylobates albibarbis inhabiting seven distinct forest types at Gunung Palung National Park, West Kalimantan, Indonesia. Population densities in montane forests (0.44 individuals/km2) were almost ten times lower than those in the next best habitat (upland granite forest; 4.2 individuals/km2) and f...
متن کاملComparing Riparian and Catchment Influences on Stream Habitat in a Forested, Montane Landscape
—Multiscale analysis of relationships with landscape characteristics can help identify areas and physical processes that affect stream habitats, and thus suggest where and how land management is likely to influence these habitats. Such analysis is rare for mountainous areas where forestry is the primary land use. Consequently, we examined relationships in a forested, montane basin between strea...
متن کاملThe herpetofauna of the cloud forests of Honduras
The cloud forest amphibians and reptiles constitute the most important herpetofaunal segment in Honduras, due to the prevalence of endemic and Nuclear Middle American-restricted species. This segment, however, is subject to severe environmental threats due to the actions of humans. Of the 334 species of amphibians and reptiles currently known from Honduras, 122 are known to be distributed in cl...
متن کاملFire disturbance, forest structure, and stand dynamics in montane forests of the southern Cascades, Thousand Lakes Wilderness, California, USA
We examined tree diameter, age structure, and successional trends in 100 montane forest plots to identify the effects of variation in the return interval, severity, and extent of fires on forest structure and dynamics in the southern Cascade Range, California. We classified 100 forest plots into 8 groups based on stand structural characteristics. Median point fire return intervals were shortest...
متن کاملFragmentation and elevation effects on bird–army ant interactions in neotropical montane forest of Costa Rica
Army ants (Formicidae: Ecitoninae) are top predators in neotropical forests. Army ant raids support a community of diverse organisms, including birds that attend the raids to collect prey. While elevation and forest fragmentation influence army ant and insectivorous bird communities, their effects on the interaction between army ants and bird species is unknown. We studied the size and species ...
