This research examined the incorporation of highly productive regions within the marine system. I combined historical conservation literature, remotely sensed oceanography, ship based surveys, satellite tagged animals, and statistical models to explore an integrated approach to the identification of key oceanic regions that require incorporation into current marine conservation strategies.

520 $a This research examined the incorporation of highly productive regions within the marine system. I combined historical conservation literature, remotely sensed oceanography, ship based surveys, satellite tagged animals, and statistical models to explore an integrated approach to the identification of key oceanic regions that require incorporation into current marine conservation strategies.
520 $a In my first chapter, I undertook a literature review of the term "hotspot", one of the most common ways by which scientists ascribe conservation prioritization in the marine and terrestrial systems. My results showed that marine literature has identified important areas of biodiversity and productivity (i.e. high primary production that results in trophic linkages and species aggregations) are in need of protection from human threats. However, current non-governmental organizations focus primarily on biodiversity, thus missing important areas of productivity for marine conservation.
520 $a In my second chapter, I demonstrated how remotely sensed oceanography, ship-based surveys, and satellite tagged animals can help to identify the formation of such a "productivity hotspot". Specifically, I examined the connection between physical forcing (surface winds and vertical Ekman upwelling), sea-surface temperature, primary production (chlorophyll-a concentrations), retentive features of fronts and dynamic height, and prey abundance (red crabs) in the spatial and temporal concentration of the critically endangered North Pacific juvenile loggerhead sea turtle (Caretta caretta) within its foraging habitat off the Pacific coast of Baja California.
520 $a Finally, in my third chapter, I identified habitat selection of loggerheads to better understand the species preference within suitable habitat. I sampled several environmental variables (depth, sea-surface temperature, and chlorophyll- a) within 'preferred' versus 'avoided' turtle habitat. Results from a generalized additive model showed the statistical importance of all three variables in the prediction of loggerhead presence within suitable habitat off of Baja California. I then incorporated prey distribution to fully explore the connection between a highly migratory species and its environment. These results show how knowledge of threatened and endangered species habitat use within a productivity hotspot can help to more efficiently identify and prioritize critical areas for conservation.
