The Mosquito (Diptera: Culicidae) Fauna Of The Blackwater Ecological Preserve: Effects Of Prescribed Burns And Habitat Type On Mosquito Abundance And Distribution, Norman A. Grefe Lll
Biological Sciences Theses & Dissertations
While mosquitoes (Diptera: Culicidae) are among the most studied of insect groups, much remains unknown about their distribution and response to environmental impacts such as prescribed burns. Blackwater Ecological Preserve, located near Zuni, Virginia, is a relict long leaf pine barren, parts of which undergo periodic prescribed burns to maintain and restore this fire-dependent ecosystem. To assess the impact of prescribed burns on mosquito activity and to determine associations between seasonal patterns of adult mosquito activity and habitat type, CDC light traps baited with dry ice were set (rom late April through October at Blackwater Ecological Preserve during the 2005 …

A largely unanswered question in the study of arboviruses is the extent to which virus can overwinter in adult vectors during the cold winter months and resume the transmission cycle in summer. Buggy Creek virus (BCRV; Togaviridae, Alphavirus) is an unusual arbovirus that is vectored primarily by the swallow bug (Hemiptera: Cimicidae: Oeciacus vicarius) and amplified by the ectoparasitic bug’s main avian hosts, the migratory cliff swallow (Petrochelidon pyrrhonota) and resident house sparrow (Passer domesticus). Bugs are sedentary and overwinter in the swallows’ mud nests. We evaluated the prevalence of BCRV and extent of …
Exploring Mitigation Options To Reduce Vehicle-Caused Mortality For The Oregon Silverspot Butterfly, Speyeria Zerene Hippolyta, Along Highway 101 At The Siuslaw National Forest, Sara B. Zielin
Environmental Science and Management Professional Master's Project Reports
The Oregon Silverspot Butterfly (OSB), Speyeria zerene hippolyta, is federally listed as "threatened." It historically inhabited coastal regions of Washington, Oregon, and California (USFWS 2001). OSB populations only remain at five sites, four of which are in Oregon; one remaining population is in California, and none exist in Washington state as they have been extirpated (BFCI 2009; USFWS 2001). The site selected for this study was Rock Creek-Big Creek, adjacent to the Siuslaw National Forest. At this site OSB habitat is bisected by Highway 101; butterflies are observed to use both sides of the highway throughout their life cycle. …
Pollinator Populations In Massachusetts Cranberry, 1990 To 2009: Changes In Diversity And Abundance, Effects Of Agricultural Intensification, And A Contribution To The North American Pollinator Survey., Molly M. Notestine
Masters Theses 1911 - February 2014
It is now widely accepted that over one-third of the global food supply depends upon pollinators. Risking severe ecological and economic implications, the status of the 4000 species of bees native to North America has been poorly understood due to a lack of long-term survey data. In this study, I conducted bee surveys on Massachusetts cranberry (Vaccinium macrocarpon Ait.) bogs from 2007-2009 and compared diversity and abundance data to those from historical surveys performed in 1990-1992 on the same bogs. I found that overall bee diversity declined severely in the 19-year survey period, while total bee abundance remained consistent. My …
The Transition Zone: Impact Of Riverbanks On Emergent Dragonfly Nymphs. Implications For Riverbank Restoration And Management, Kirsten Hope Martin
The Transition Zone: Impact Of Riverbanks On Emergent Dragonfly Nymphs. Implications For Riverbank Restoration And Management, Kirsten Hope Martin
Antioch University Full-Text Dissertations & Theses
The use of riprap in the restoration and stabilization of riverine landscapes is an issue of concern for many ecologists. While current methods of bank stabilization, especially those involving the placement of rocks (riprap) along the waterline, are effective in controlling erosion their presence changes habitat components (slope, substrate composition, near-shore river velocity) at the river-land interface. The additional impacts of river current, water temperature, soil composition, slope, and water level fluctuation, may further imperil emerging nymphs. The purpose of this research is to document the effects of riprap, location (upriver or downriver of hydroelectric intake/outtake facilities), water level fluctuation, …
