Diet analyses of pollinator predators in sage scrub and chaparral ecosystems

Fire as a Threat to Biodiversity in Fire-Type Shrublands

Chaparral and coastal sage scrub communities have a disproportionately high number of rare and endangered plants and thus are of particular conservation concern. Unnaturally high fire frequency has been a leading cause of degradation of chaparral and coastal sage scrub ecosystems. Although these shrublands are fire-adapted, below a certain threshold of fire frequency, resilience is inversely re...

Coastal Sage Scrub Succession1

Professor of Geography, University of California, Los Angeles, California 90024 USA Abstract: Unlike chaparral, shrubs of coastal sage are capable of continual seedling reproduction. As a result, mixed-aged stands form which show little senescence. Litter turnover is twice as rapid. The more open sage scrub canopy permits persistence of a diverse herb layer into mature communities. Crown sprout...

Comparison of post-®re seedling establishment between scrub communities in mediterranean and non- mediterranean climate ecosystems

1 Both ®re regimes and the conditions under which ®res occur vary widely. Abiotic conditions (such as climate) in combination with ®re season, frequency and intensity could in ̄uence vegetation responses to ®re. A variety of adaptations facilitate post-®re recruitment in mediterranean climate ecosystems, but responses of other communities are less well known. We evaluated the importance of clima...

When Chaparral and Coastal Sage Scrub Burn: Consequences for Mammals, Management, and More

Comparative Nutrient Relations in Adjacent Stands of Chaparral and Coastal Sage Scrub1

Research Associate, Department of Biological Sciences, University of California, Santa Barbara, California, 93109. Abstract: Productivity and nutrient cycling parameters were measured in mature stands of chaparral and coastal sage scrub in the Santa Monica Mountains, California, USA. Net annual production and the magnitude of annual nutrient transfers were much greater in the evergreen chaparra...
