Harbor seals have been listed as a species likely to benefit from new Marine Protected Areas (MPAs) in California as part of the Marine Life Protection Act. Whereas seals may experience direct and indirect effects from these MPAs as a whole, the impac . . .

European beachgrass (Ammophila arenaria (L.) Link) is fully naturalized in central and northern California and has supplanted native populations of dune vegetation in many areas. Managers at The Nature Conservancy's Lanphere Christensen Dunes Preserve . . .

An understanding of population demographics is a key component for developing successful wildlife conservation and management plans. However, elusive and secretive carnivores such as river otters can be difficult to trap and observe, making investigat . . .

The invasive salt marsh cordgrass Spartina densiflora degrades native salt marsh ecosystems by altering abiotic processes and reducing native biodiversity. The dispersal of S. densiflora seeds on tidal currents poses a threat to restoration sites and . . .

Humboldt Bay is one of the largest and most biologically important estuaries in California functioning as a habitat, food source, breeding ground, and nursery area for a host of marine animals. Understanding mechanisms which increase turbidity in ecol . . .

Black brant (Branta bernicla nigricans) breed in the Arctic and sub-Arctic in spring, a time when food resources are limited. They rely largely on energy stores, acquired at staging sites, for migration and to support egg laying and incubation. In Cal . . .

Although Humboldt Bay was considered to be a major wintering area for black brant (Branta bernicla nigricans) in the 1890's, the evidence suggests that since at least 1930 it has not supported a large wintering brant population, but instead serves pri . . .

Humboldt Bay is a natural deep water port located in Eureka, California and is the gateway to the ecotourism opportunities available in the Humboldt region. As a port on the United States west coast the Port of Humboldt is along the route taken by cru . . .

Humboldt Bay, in far northern California receives a large amount of sediment, predominantly silts and clays from the surrounding watersheds at an estimated 62,532 metric tons/yr. (Barrett 2004). Fine grained sediments such as silts and clays have a hi . . .

Genetic structure and diversity of populations can impact the productivity and resilience of ecosystems. In Humboldt Bay, California (USA) eelgrass (Zostera marina) is the dominant marine plant at low intertidal and shallow subtidal elevations where i . . .
