Analysis of bank erosion on the Merced River, Yosemite Valley, Yosemite National Park, California, USA Analysis of bank erosion on the Merced River, Yosemite Valley, Yosemite National Park, California, USA
Channel changes from 1919 to 1989 were documented in two study reaches of the Merced River in Yosemite National Park through a review of historical photographs and documents and a comparison of survey data. Bank erosion was prevalent and channel width increased an average of 27% in the upstream reach, where human use was concentrated. Here, trampling of the banks and riparian vegetation...

Avian species richness in different-aged stands of riparian forest along the middle Rio Grande, New Mexico Avian species richness in different-aged stands of riparian forest along the middle Rio Grande, New Mexico
Riparian forests are important for maintaining vertebrate species richness in the southwestern United States, but they have become restricted in distribution due to both historical and current management practices. In order to counteract continued loss of this habitat, several mitigation programs were developed in the middle Rio Grande Valley of New Mexico. Three areas ranging from 50 to...

Distribution and conservation status of coastal sage scrub in southwestern California Distribution and conservation status of coastal sage scrub in southwestern California
A landscape-based characterization of vegetation has been developed for southwestern California using satellite imagery, air photos, existing vegetation maps, and field data. Distribution maps of nine dominant coastal scrub species and 13 species assemblages that were identified by divisive information analysis have been analyzed to quantify spatial patterns of species co-occurrence...

Lack of association between magnetic patterns and the distribution of free-ranging dolphins Lack of association between magnetic patterns and the distribution of free-ranging dolphins
While free-ranging dolphins (Delphinus sp.) have been shown to be associated with bottom topography (depth contours of the sea floor), stranded dolphins have been shown to be associated with magnetic topography. Association with magnetic patterns that may be useful for orientation and navigation by free-ranging dolphins has not been demonstrated. Evaluation of the same 140 locations of...

History and present status of the northern elephant seal population History and present status of the northern elephant seal population
The northern elephant seal, Mirounga angustirostris , was presumed extinct by 1892 owing primarily to commercial harvesting for their blubber oil that began in the early 1800s. A small, residual breeding colony survived, however, and with legal protection from further hunting, it grew rapidly through the early 1900s. Immigrants steadily colonized other island and mainland sites in Baja...
