Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:

Litz, Marisa N. C.

Abstract:

Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

Habitat associations of bird communities in shrub-steppe and western juniper woodlands

Creator:

Reinkensmeyer, Daniel P.

Abstract:

The encroachment of western juniper into mountain big sagebrush plant communities and the subsequent development of juniper stands results in significant changes in vegetation structure and complexity. This study described and compared vegetative structure and bird community measures among four cover types representing a broad range of structural stages among...

Aboveground biomass and ecosystem carbon pools in tropical secondary forests growing in six life zones of Costa Rica

Creator:

Cifuentes Jara, Miguel

Abstract:

Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...
