Book Description
Small mammals are among the many taxa in the diverse southern Californian coastal sage scrub and chaparral ecosystems that are threatened by the exotic plant invasions, habitat destruction and fragmentation that have accompanied continued urbanization. Many small mammals not only rely on coastal sage scrub vegetation for shelter but also eat shrub seeds, and therefore depend upon their habitat while also having the ability to shape it. The studies presented here examine the effects of an El Niño-associated heavy rainfall event and invasion by exotic grasses on the small mammal community as well as the role of small mammals in mediating competition between native and exotic plants via selective seed predation. A 4 yr study that included the 1997-1998 El Niño (ENSO) rainfall event investigated changes in density and spatial distribution for 11 rodent species. In the period during and immediately after ENSO, 7 species increased in density and showed range expansions into previously unoccupied areas. The endangered kangaroo rat Dipodomys stephensi declined in abundance and spatial distribution during ENSO. A principle components analysis qualitatively showed changes in small mammal community composition that resulted from differences in relative abundance due to differing magnitudes of species' responses to high precipitation. Most species returned to pre-ENSO population densities and range sizes within 2 yr after El Niño. In addition to the transitory responses to the additional resources available after periods of high precipitation, small mammals also responded to longer-term, perhaps permanent, habitat changes resulting from disturbance-facilitated exotic grass invasions. At higher levels of invasion, abundance of shrub-associated small mammals declined while grass-associated species increased, and overall density of all small mammal species declined. Although no species exhibited a threshold response to invasion, invaded areas supported a depauperate mammal community largely composed of generalist species. Finally, a seed predation study found that rodents preferentially consumed seeds of exotic grasses and forbs over those of native shrubs and grasses. Total mass of seed removed and rates of seed tray visitation varied by season and small mammal density, but a preference for exotic seeds showed that small mammals might slow rates of exotic plant invasion

Book Description
Invasions by exotic grasses, particularly annuals, rank among the most extensive and intensive ways that humans are contributing to the transformation of the earth’s surface. The problem is particularly notable with a suite of exotic grasses in the Bromus genus in the arid and semiarid regions that dominate the western United States, which extend from the dry basins near the Sierra and Cascade Ranges across the Intermountain Region and Rockies to about 105° longitude. This genus includes approximately 150 species that have a wide range of invasive and non-invasive tendencies in their home ranges and in North America. Bromus species that became invasive upon introduction to North America in the late 1800’s, such as Bromus tectorum and B. rubens, have since became the dominant cover on millions of hectares. Here, millenia of ecosystem development led to landscapes that would otherwise be dominated by perennial shrubs, herbs, and biotic soil crusts that were able to persist in spite of variable and scarce precipitation. This native ecosystem resilience is increasingly coveted by land owners and managers as more hectares lose their resistance to Bromus grasses and similar exotics and as climate, land use, and disturbance-regime changes are also superimposed. Managers are increasingly challenged to glean basic services from these ecosystems as they become invaded. Exotic annual grasses reduce wildlife and livestock carrying capacity and increase the frequency and extent of wildfi res and associated soil erosion. This book uses a unique ecoregional and multidisciplinary approach to evaluate the invasiveness, impacts, and management of the large Bromus genus. Students, researchers, and practitioners interested in Bromus specifically and invasive exotics in general will benefit from the depth of knowledge summarized in the book.

Book Description
A great many terrestrial plants live in close association with fungi. The features of this association, which is known as mycorrhiza, are those of a mutualistic symbiosis. Almost all plants from mycorrhizae whereby the fungus provides soil resources to the plant in exchange for energy provided by the plant. The symbiosis means greater productivity under stress for the plant and a steady energy supply for the fungus. This book addresses the diverse and complex ways in which mycorrhizae affect the mechanism for plant survival as individuals and populations, for community structure and functioning. An evolutionary/ecological approach is used to describe how and under what conditions mycorrhizal symbioses range from managing natural and agricultural lands to biotechnological processes that enhance agricultural productivity and sustainability. The Ecology of Mycorrhizae will be an invaluable book, applicable to all levels of theoretical and applied research in agronomy, botany, ecology, environmental microbiology, and plant pathology.
