Insect Herbivory in the Transition to California Annual Grasslands: Did Grasshoppers Deliver the Corennial bunch grasses to introduced, annual grass species (Jackson 1985). Since specific information concerning grasshoppers from California grasslands is generally lacking, I will summarize patterns and processes of grasshopper feeding from other North American grasslands and suggest possible mecha

In order to persist, the plants must produce seeds before the summer drought and disperse a significant portion of these seeds to favorable locations in the seedbed where they await moisture events of sufficient magnitude in the fall to trigger germination.

Here, we address two issues about the comparative ecology of annual grass species in their homeland and in California: first, their different ecological roles in the two regions, and second, characteristics that preadapted these plants to conditions in California.

This chapter discusses interrelationships between climate and soil characteristics, with emphasis on how these abiotic factors influence structure, composition, and productivity of plant communities of the grasslands.

This paper concerns a subset of this larger issue, namely, the impacts of vertebrate animals in California grassland communities. No one would deny the profound effects on this community-type imposed by grazing livestock. But what about non-domesticated vertebrates?
