We analyzed the sedimentological characteristics and magnetic properties of cores from the three basins of Clear Lake, California, USA, to assess the depositional response to a series of land use changes that occurred in the watershed over the 20th century. Results indicate that distinct and abrupt shifts in particle size,...
Genetic-modification strategies are currently being developed to reduce the transmission of vector-borne diseases, including African trypanosomiasis. For tsetse, the vector of African trypanosomiasis, a paratransgenic strategy is being considered: this approach involves modification of the commensal symbiotic bacteria Sodalis to express trypanosome-resistance-conferring products. Modified Sodalis can then be driven into...
Density estimation for marine mammal species is performed primarily using
visual distance sampling or capture-recapture. Minke whales in Hawaiian waters
are very difficult to sight; however, they produce a distinctive “boing” call, making
them ideal candidates for passive acoustic density estimation. We used an array of
14 bottom-mounted hydrophones, distributed...
The effects of Marine protected areas (MPAs) on adult fish populations depend on the degree of protection provided, which is partly a function of MPA size and the spatial extent of fish movements. The Redfish Rocks Marine Reserve (RRMR) and MPA, located on the south coast of Oregon near Port...
"The American Dream" is an expression familiar to all Americans and the realization of the American Dream is tied closely to homeownership (Clinton, 1995). The recent financial crisis, with the housing and financial markets at levels not seen since the Great Depression, has resulted in widespread unemployment, continually dropping home...
For the past thirty years the majority of the
research on the cognitive demands of learning computer
programming has assumed that successful computer
programmers display certain aptitudes. Some
researchers indicate that studies linking different
prerequisite profiles of abilities to different
programming outcomes are needed. Such research might
dispel many of...
The energy distribution of electrons in Townsend discharges in
helium has been experimentally investigated in a direct fashion.
A discharge is initiated between parallel plates of a small cell
mounted at the center of a spherical retarding field energy analyzer.
The anode of the cell is perforated and some electrons...
The fishes of Upper Klamath Lake appeared to distribute
themselves in three general groups during the summers of 1964
and 1965: (1) the chubs--unrestricted as to distribution with slight
seasonal variations; (2) rainbow trout and yellow perch -- restricted
to certain water conditions that exist only along the northern marsh...
