Surface Heating and Patchiness in the Coastal Ocean off Central California During a Wind Relaxation Event

Creator:: Ramp, Steven R., Garwood, Roland W., Davis, Curtiss O., and Snow, Richard L.
Abstract:: The difference between the temperature of the ocean at 4-cm and 2-m depth was continuously monitored during a cruise to the coastal transition zone off Point Arena, California (38°58′N, 123°45′W), during June 1987. The two temperatures were coincident most of the time but diverged during one nearshore leg of the...

A novel landscape ecology approach for determining microhabitat correlations and faunal patchiness in extreme environments:pilot study for the Southern East Pacific Rise at 17-18° S

Creator:: Wargo Rub, Michelle
Abstract:: Since their discovery in 1977, hydrothermal vent communities have offered scientists a unique glimpse into a world that is supported primarily by chemically derived energy rather than direct energy from the sun. Furthermore, studies of hydrothermal vent ecosystems have introduced scientists to amazing animals that have successfully adapted to living...

Bottom-up regulation of a pelagic community through spatial aggregations - not biomass

Creator:: Benoit-Bird, Kelly J. and McManus, Margaret A.
Abstract:: The importance of spatial pattern in ecosystems has long been recognized. However, incorporating patchiness into our understanding of forces regulating ecosystems has proven challenging. We used a combination of continuously sampling moored sensors complemented by shipboard sampling to measure the temporal variation, abundance, and vertical distribution of four trophic levels...

The effects of transect direction on observed spatial patterns of chlorophyll in Lake Tahoe

Creator:: Abbott, Mark R., Powell, Thomas M., and Richerson, Peter J.
Abstract:: Horizontal transects of fluorescence measurements have been used extensively to investigate phytoplankton patchiness. Variance spectra have been calculated from these data, thus quantifying spatial heterogeneity as a function of length scale. Analysis of such fieldwork and associated theoretical investigations is based on the assumption that horizontal patchiness is isotropic. Three...

Designing effective reserve networks for nonequilibrium metacommunities

Creator:: Gouhier, Tarik C., Guichard, Frederic, and Menge, Bruce A.
Abstract:: The proliferation of efficient fishing practices has promoted the depletion of commercial stocks around the world and caused significant collateral damage to marine habitats. Recent empirical studies have shown that marine reserves can play an important role in reversing these effects. Equilibrium metapopulation models predict that networks of marine reserves...

Foraging behavior of northern fur seals closely matches the hierarchical patch scales of prey

Creator:: Benoit-Bird, Kelly J., Battaile, Brian C., Nordstrom, Chad A., and Trites, Andrew W.
Abstract:: Marine prey often occur in hierarchical mosaics whereby small, high-density patches are nested inside of larger, lower density aggregations. We tested the extent to which the foraging behavior of a marine predator (northern fur seal Callorhinus ursinus) could be explained by the hierarchical patch structure of a dominant prey species...

The spatial dynamics of renewable resource use

Creator:: Jardine, Sunny, Abbott, Joshua, and Sanchirico, James N.
Abstract:: In the past two decades resource economists have made great headway in understanding spatial-dynamic processes in resource exploitation and management. However, despite this progress, there remain large gaps in understanding the spatialdynamics of recreational resources. Here we first develop a general bioeconomic model of a renewable recreational resource use, under...

The Influence of Prey Predictability on the Foraging Behavior and Movement of Intertidal Predators

Creator:: Hennessey, Shannon M.
Abstract:: Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...

A critical scale in plankton aggregations across coastal ecosystems

Creator:: Benoit-Bird, Kelly J., Shroyer, Emily L., and McManus, Margaret A.
Abstract:: We examined the characteristics of biological patches at four different locations to assess the relationship of patch vertical scale, amplitude, and persistence. In contrast to patches of larger animals, we found that the majority of coherent aggregations of plankton at each site were vertically compressed, with most smaller than 5m...

Johnson/Sheepy Creek riparian reserve vegetation treatments

Creator:: United States. Bureau of Land Management and Klamath Falls Resource Area
Abstract:: The proposed action is to thin understory trees from around ponderosa pine, sugar pine, white pine, and Douglas fir in the outer portion of Riparian Reserves in the Jenny Creek watershed. The overall objective is to maintain and restore the diversity of forest stands near streams in a way that...
