Terrestrial Macroinvertebrate Fauna Under Logs In Primary And Secondary Forest, November 2005, Erica Hoaglund
Terrestrial Macroinvertebrate Fauna Under Logs In Primary And Secondary Forest, November 2005, Erica Hoaglund
Tropical Ecology and Conservation [Monteverde Institute]
Terrestrial macroinvertebrates are an important yet understudied group. They are present in all types of tropical forests and, due to their services as decomposers, are essential for the maintenance of a productive system. The purpose of this study was to determine if there were significant differences in diversity and community composition between macroinvertebrate communities in the primary versus secondary lower montane wet forest of Monteverde, Costa Rica. Macroinvertebrates were collected from under 20 logs in primary and 20 logs in secondary forest. Primary forest had a higher diversity of macroinvertebrates (H’ = 2.5) than secondary forest (H’ = 2.05). Primary …
Tardigrade Evolution And Ecology, Phillip Brent Nichols
Tardigrade Evolution And Ecology, Phillip Brent Nichols
USF Tampa Graduate Theses and Dissertations
A character data set suitable for cladistic analysis of tardigrades at the family level was developed. The data matrix consisted of 50 morphological characters from 15 families of tardigrades and was analyzed by maximum parsimony. Kinorhynchs, loriciferans and gastrotrichs were used as outgroups. The results agree with the currently accepted hypothesis that Eutardigrada and Heterotardigrada are distinct monophyletic groups. Among the eutardigrades, Eoyhypsibiidae was found to be a sister group to Macrobiotidae + Hypsibiidae, while Milnesiidae was the basal eutardigrade family. The basal heterotardigrade family was found to be Oreellidae. Echiniscoideans grouped with some traditional Arthrotardigrada (Renaudarctidae, Coronarctidae + Batillipedidae) …
Assessment Of Resource Selection Using Remote Sensing And Geographic Information Systems (Gis) For Two Vertebrates In Disparate Habitats: The Gopher Tortoise (Gopherus Polyphemus) And The North Atlantic Right Whale (Eubalaena Glacialis), Cherie A. Keller
USF Tampa Graduate Theses and Dissertations
This dissertation is a treatise on spatially-explicit resource selection on two very different vertebrate species. The North Atlantic right whale (Eubalaena glacialis) is the most endangered large whales in the world. Ship strikes and fishing gear entanglement are impediments to recovery. The gopher tortoise (Gopherus polyphemus) is an imperiled species whose upland habitats are shrinking from urban and agricultural development. Determining spatial distribution of important resources is important for conservation strategies. Historical and modern thinking of habitat selection theory and analytical techniques are reviewed and applied to these species. Fine-scale resource selection of sea surface temperature …
Diets And Coexistence Of The Sea Urchins Lytechinus Variegatus And Arbacia Punctulata (Echinodermata) Along The Central Florida Gulf Coast, Janessa Cobb, John M. Lawrence
Diets And Coexistence Of The Sea Urchins Lytechinus Variegatus And Arbacia Punctulata (Echinodermata) Along The Central Florida Gulf Coast, Janessa Cobb, John M. Lawrence
Integrative Biology Faculty and Staff Publications
The basis for coexistence of similar species is fundamental in community ecology. One mechanism for coexistence is differentiation of diets. Lytechinus variegatus and Arbacia punctulata coexist in different microhabitats along the Florida gulf coast. Their great difference in morphology might affect their choice of microhabitats and diet. We analyzed diets of both species at 1 offshore and 1 nearshore site where both occurred in relatively equal numbers, an offshore site dominated by A. punctulata and an offshore site dominated by L. variegatus. Gut contents were analyzed to determine the diet. A. punctulata prim. consumed sessile invertebrates except on dates …
Weaving Traditional Ecological Knowledge Into The Restoration Of Basketry Plants, Daniela Shebitz
Weaving Traditional Ecological Knowledge Into The Restoration Of Basketry Plants, Daniela Shebitz
Journal of Ecological Anthropology
This paper focuses on the benefits of incorporating traditional ecological knowledge into the field of ecological restoration. Case studies on indigenous use of sweetgrass in New York State, U.S.A (Haudenosaunee Nation), and beargrass in Washington State, U.S.A (Quinault and Skokomish Nations), are presented. Both studies focus on the restoration of basketry plants by incorporating indigenous knowledge of changes in abundance of culturally significant plants; knowledge of sites appropriate for restoration of culturally significant plants; and knowledge of land management methods to restore species and/or habitats. Open-ended, semi-formal, and informal interviews were conducted with indigenous consultants familiar with the plant and/or …
