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...

Forest management worldwide is increasingly focused on values such as biodiversity conservation, carbon, water and recreation as well as timber production. Ownership and governance arrangements are also changing, with an increase in private ownership of forest resources that is focused on timber production and devolution of management and control to the community level. Forest management is par...

The path and magnitude of future anthropogenic emissions of carbon dioxide will likely influence changes in climate that may impact the global forest sector. These responses in the global forest sector may have implications for international efforts to stabilize the atmospheric concentration of carbon dioxide. This study takes a step toward including the role of global forest sector in integrat...

Climate change affects forests both directly and indirectly through disturbances. Disturbances are a natural and integral part of forest ecosystems, and climate change can alter these natural interactions. When disturbances exceed their natural range of variation, the change in forest structure and function may be extreme. Each disturbance affects forests differently. Some disturbances have tig...

Leaf area index (LAI) is an important structural characteristic of forest ecosystems which has been shown to be strongly related to forest mass and energy cycles and forest productivity. LAI is more easily measured than forest productivity, and so a strong relationship between LAI and productivity would be a valuable tool in forest management. While a linear relationship has been observed betwe...

As habitat for the golden-headed lion tamarin (GHLT; Leontopithecus chrysomelas) in Brazil’s Atlantic forest becomes smaller and more fragmented, remaining large forest patches may be critical to the persistence of the species. The objectives of our study were to identify the forest patch size that could support a viable population of GHLTs under a range of risk scenarios and to locate patches ...

This study compared two alternative techniques for predicting forest cover types from cartographic variables. The study evaluated four wilderness areas in the Roosevelt National Forest, located in the Front Range of northern Colorado. Cover type data came from US Forest Service inventory information, while the cartographic variables used to predict cover type consisted of elevation, aspect, and...

So profoundly has this river modified the effects of the general grassland climate that in many places prairie has given way to woodland and forest. Several distinct forest communities along the river in southeastern Nebraska and adjacent parts of Kansas, Missouri, and Iowa extend for short distances over the uplands, but farther along the major streams. Most of the trees and shrubs of this for...

To modeling of Suitability Iranian Oak site to establish coppice regenerations, chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, southern Zagros forest, and southwest Iranian state was selected. To modeling Suitability Iranian Oak used the physiographic element, soil depth, climatology and distance from village selected. To this study used the raster formats by pixel...

— In this paper we assess the institutional and environmental impacts of forest decentralization in Bolivia, Kenya, Mexico, and Uganda. We develop theories of institutional impacts based upon the specific content of decentralization reforms. We classify each country’s reforms in terms of the creation/change in local user group empowerment and accountability mechanisms. Using data from the Inter...
