Calibration Of Remotely Sensed, Coarse Resolution Ndvi To Co2 Fluxes In A Sagebrush–Steppe Ecosystem, Bruce K. Wylie, Douglas A. Johnson, Emilio Laca, Nicanor Z. Saliendra, Tagir G. Gilmanov, Bradley C. Reed, Larry L. Tieszen, Bruce B. Worstell Jan 2003

Calibration Of Remotely Sensed, Coarse Resolution Ndvi To Co2 Fluxes In A Sagebrush–Steppe Ecosystem, Bruce K. Wylie, Douglas A. Johnson, Emilio Laca, Nicanor Z. Saliendra, Tagir G. Gilmanov, Bradley C. Reed, Larry L. Tieszen, Bruce B. Worstell

United States Geological Survey: Staff Publications

The net ecosystem exchange (NEE) of carbon flux can be partitioned into gross primary productivity (GPP) and respiration (R). The contribution of remote sensing and modeling holds the potential to predict these components and map them spatially and temporally. This has obvious utility to quantify carbon sink and source relationships and to identify improved land management strategies for optimizing carbon sequestration. The objective of our study was to evaluate prediction of 14-day average daytime CO2 fluxes ( Fday) and nighttime CO2 fluxes (Rn) using remote sensing and other data. Fday …

Connectivity Between Coastal Habitats Of Two Oceanic Caribbean Islands As Inferred From Ontogenetic Shifts By Coral Reef Fishes, I. Nagelkerken, G. Van Der Velde Jan 2003

Connectivity Between Coastal Habitats Of Two Oceanic Caribbean Islands As Inferred From Ontogenetic Shifts By Coral Reef Fishes, I. Nagelkerken, G. Van Der Velde

Gulf and Caribbean Research

Mangroves and seagrass beds are considered important nursery habitats for juveniles of coral reef fishes. Studies have mostly focused on the fish community of just one habitat, so the connectivity between different coastal habitats is often unclear. In this study, density and size of reef fish were determined using a single sampling technique in four non-estuarine bay habitats and four reef zones in Curaçao and Bonaire (Netherlands Antilles). The data indicate that of the complete reef fish community at least 21 species show ontogenetic crossshelf shifts in habitat utilization. The 21 species mainly utilized shallow-water habitats (mangroves, seagrass beds, channel …

Influence Of Natural And Anthropogenic Disturbance On The Soft Bottom Macrobenthic Community Of The Campeche Bank, Mexico, Hector Abuid Hernandez-Arana Jan 2003

Influence Of Natural And Anthropogenic Disturbance On The Soft Bottom Macrobenthic Community Of The Campeche Bank, Mexico, Hector Abuid Hernandez-Arana

School of Biological and Marine Sciences Theses

The structure of macrobenthic communities was investigated in carbonate and transitional carbonate-terrigenous sediments of the Southern Gulf of Mexico (Campeche Bank). The aim was to assess the influence of natural disturbance represented by winter storms and river runoff and the putative influence of oil-related activities using a regional approach. At a scale of > 100 km community composition of benthic macroinfauna was characterised as distinct assemblages within the carbonate and transitional sedimentary provinces controlled by natural disturbance. The carbonate assemblage was numerous and diverse influenced by a heterogeneous substratum. Winter storms had a severe impact with mortality probably resulting from abrasion …

The seasonal dynamics and spatial distributions of Anopheles mosquitoes and Plasmodium falciparum parasites were studied for one year at 30 villages in Malindi, Kilifi, and Kwale Districts along the coast of Kenya. Anopheline mosquitoes were sampled inside houses at each site once every two months and malaria parasite prevalence in local school children was determined at the end of the entomologic survey. A total of 5,476 Anopheles gambiae s.l. and 3,461 An. funestus were collected. Species in the An. gambiae complex, identified by a polymerase chain reaction, included 81.9% An. gambiae s.s., 12.8% An. arabiensis, and 5.3% An. merus. Anopheles …

Fictions Of Nature: Ecology, Science, And Culture In Twentieth-Century British Literature., Neal Bukeavich Jan 2003

Fictions Of Nature: Ecology, Science, And Culture In Twentieth-Century British Literature., Neal Bukeavich

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines twentieth-century British fiction concerned with humankind's interactions with the nonhuman world. I analyze a range of literary works, including H. G. Wells's The Food of the Gods (1903), D. H. Lawrence's The Rainbow (1915), Women in Love (1920), and Lady Chatterley's Lover (1928), John Brunner's Stand on Zanzibar (1968), Graham Swift's Waterland (1983), and J. G. Ballard's Rushing to Paradise (1994). This body of literature remains largely unexamined for its treatments of ecological issues and belongs to a national history deeply implicated in local and global environmental change. Moreover, my consideration of this literary tradition marks a …
