Retired farmland in the western San Joaquin Valley (SJV) of California is frequently colonized by invasive plants that may limit the establishment of native flora. Limited ecophysiological data on native and invasive SJV plant species constrains scien . . .

The purpose of this paper is to describe some of the factors which influence seed germination and seedling survival or the California Buckeye and to relate these factors to the distribution pattern. Benseler (1969) found that-most seed and seedling mo . . .

Amphibians "that: breed in temporary bodies of water are confronted with problems of pool availability and larval mortality due to dessication of the breeding pools. Due to the low normal rainfall during the spring of the year, the mortality to the la . . .

An increased interest has been shown in the exotoxins of the bacterium Staphylococcus aureus and their relationship to disease since 1872 when Klebs, speaking of staphylococcal infections, suggested that these organisms produce disease by means of dif . . .

The present study- concerned the quantitative and qualitative comparison of two intertidal benthic algal floras. Data were collected from the experimental area, Ano Nuevo Point, and Pigeon Point the control area, both in San Mateo County California (F . . .

Considerable evidence links cumulative and sustained exposure to estrogens to breast tumor proliferation. Chemicals with estrogenic activity can bind to the estrogen receptor (ER) to affect downstream signaling of estrogen-responsive genes. Organochlo . . .

There exists among genetic forms the simplest self-replicating biological entity; namely, the "viruses." To define the term "virus" is not easy, for viruses cannot be defined by common-sense criteria the way animals and plants can. The term "virus" wa . . .

The purpose of the present study is to gain some insight into the complex of factors that create the canopy effect with emphasis on the microenvironment that is associated with the vegetative differences. Data recorded weekly included the measurement . . .

Petrolisthes cinctipes and P. manimaculis are two closely related species of anomurans that live in the upper intertidal zone along the Central California coast. Morphometric measurements were collected to gain insight on the reproductive cycles of th . . .
