Comparative Ecology of Annual Grasses: Native Versus Californian Habitats and Populations,a has been attributed to their high densities (Bartolome 1979; Young et al. 1981) and to their ability to complete their life cycles in the short period of water availability (Gulmon 1979; Ewing and Menke 1983). Here, we address two issues about the comparative ecology of annual grass species in the

Insect Herbivory in the Transition to California Annual Grasslands: Did Grasshoppers Deliver the Coups of herbivores in grasslands, insects such as grasshoppers (Orthoptera: Acrididae) are very common and intermittently remove large portions of the above-ground biomass (Hewitt 1977, 1978). Immediate losses to grasshoppers are often obvious, especially when densities are high. However, the net eff

Impacts of Non-Domesticated Vertebrates on California Grasslands,ated the volume of English soil turned over by earthworms. In spite of this, there is a latent tendency among plant-oriented ecologists to harbor the view that animals, while being responsive to the plant community, are not likely to have much effect upon it. Fortunately, this bias is rapidly disapp

Simulated Water Budgets for an Annual Grassland Site in the Sierra Foothills,sequence, the season with warm temperatures and the season of high precipitation are out of phase for plant growth. In addition, the length of the period of moisture availability varies, as does the total amount of precipitation (Evans et al. 1975, Major 1977). In this paper, a water-budget model wa

,Conservation Biology of California’s Remnant Native Grasslands, heavy scars from its relatively short history since the first Europeans arrived. But none of California’s landscape has been so irreparably altered as its grasslands. These grasslands have undergone habitat conversion including cultivation, grazing, suburbanization and industrialization. They have

The California Annual Grassland: An Overview,h at several field sites was carried out as part of the Grassland Biome project. Unfortunately, no single synthesis volume resulted from the California work, but a precursor was published by the University of California’s Institute of Ecology (U.C. Davis), based on a symposium sponsored by the Calif
