Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:

Miller, Todd William

Abstract:

The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

A geographical framework for assessing longitudinal patterns in stream habitat and fish distribution

Creator:

Torgersen, Christian E.

Abstract:

New approaches are needed to quantify and understand spatial patterns of stream fishes and their environment. Concepts in riverine ecology emphasize the importance of thermal zones and gradual longitudinal changes in physical habitat and biota, but little is known about spatial variability within the river continuum. I present a conceptual...

Quantitative Tools for Monitoring Strategy Evaluation and Assessment of Sea Turtle Populations

Creator:

Piacenza, Susan E. H.

Abstract:

Green sea turtles, Chelonia mydas, have endangered and threatened populations globally, but several populations show signs of population recovery. In Hawaii, nesting female green turtles have increased 5.7% year⁻¹ since 1973, but wide fluctuations in census counts of nesting females make recovery diagnosis difficult. For effective management planning, it is...
