Managing Sierra Nevada Forests
Fire will continue to be a major management challenge in mixed-conifer forests in the Sierra Nevada. Fire is a fundamental ecosystem process in these forests that was largely eliminated in the 20th century. Fire reintroduction is a critical goal but is subject to constraints such as smoke production, risk of fire moving outside designated boundaries, the expanding wildland-urban interface, and ...
متن کاملFire in the Sierra Nevada
Fire has been described as both a major ecological force necessary for long-term functioning of Sierra Nevada ecosystems and as one of the greatest threats to human and natural resources (SNEP 1996a). Fire has shaped the terrestrial ecosystems of the Sierra Nevada for millennia. Before the mid-1800s, fires generally were frequent and mostly of low to moderate intensity, from lower-elevation blu...
متن کاملNeurobiology of Monarch Butterfly Migration.
Studies of the migration of the eastern North American monarch butterfly (Danaus plexippus) have revealed mechanisms behind its navigation. The main orientation mechanism uses a time-compensated sun compass during both the migration south and the remigration north. Daylight cues, such as the sun itself and polarized light, are processed through both eyes and integrated through intricate circuit...

متن کاملCharacterizing fire severity patterns in three wildland fire use incidents in the southern Sierra Nevada
Wildland fire use (WFU) is a tool that has been utilized by managers in the Forest Service since the 1970s to reintroduce fire as a natural ecosystem process. Today it is also applied to meet additional resource objectives including restoration and maintenance of ecosystems and fire hazard reduction through lessening the extent and severity of future fires. Few studies have characterized the sp...
