Ranch ponds are numerous in the foothills of the western Sierra Nevada. An article appearing in the California Cattleman (anon, 1975) estimated that there were more than 50,000 ponds of less than 0.0123 cubic hectometers (10 acre feet) in California. . . .

Two hemipterans, Oncopeltus fasciatus Dallas (Lygaeidae) and Leptocoris trivittatus Say (Corizidae) (Feir, 1974; Woolley, 1949), have been used extensively in research and teaching due to availability and/or ease of rearing. The common squash bug, . . .

Waters containing enteropathogenic microorganisms (i.e., Salmonella, Shigella) are considered unsafe for human consumption. Traditionally, indicator bacteria have been utilized for the assess- ment of bacteriologically unsafe waters. However, a d . . .

Bush Anemone (Carpenteria californica Torr.) is a rare endemic shrub that exists within a limited range in Eastern Fresno County, California. Little floristic or vegetation research has been conducted on the species in its natural environment. The . . .

Following the methods of Gardner and Gardner (1969) and Premack and Premack (1972), others have continued human- pongid two-way communication studies elaborating upon the procedures of both the former investigators. Fouts (1973), after the Gar . . .

Farm ponds are small man-made resevoirs used for watering of farm animals, irrigation and fishing. Because of their small size, farm ponds are susceptible to rapid eutrophication which can cause growth of noxious or poisonous algae, unpleasant odor . . .

This three year study (1970-1972) was undertaken to document reproductive success in a colony of great blue herons at the San Joaquin River Heronry, Merced County, California. Quantitative data were collected on incubation period, clutch size, ha . . .

Bacterial second messenger, c-di-GMP, regulates important functions such as biofilm formation, motility, and virulence. C-di-GMP also has an immunostimulatory property, so can be used as a vaccine adjuvant. In this project, DgcZ (a diguanylate cycla . . .

Tunneling nanotubes (TNTs) have been recently discovered as an essential form of cell-cell communication in multicellular organisms. Although TNTs appear to be an important cell-cell signaling pathway, its mechanism of formation and functions are st . . .
