State Coastal Observations And Monitoring Needs: Results Of A Survey To Assess Coastal Management Needs (Draft Report), Jeff Benoit, Chantal Lefebvre, Dan Hellin, Regan Maund, Jack Thigpen May 2004

State Coastal Observations And Monitoring Needs: Results Of A Survey To Assess Coastal Management Needs (Draft Report), Jeff Benoit, Chantal Lefebvre, Dan Hellin, Regan Maund, Jack Thigpen

Urban Harbors Institute Publications

The success of the U.S. Coastal Ocean Observing System will be measured, in part, by how well the needs of the coastal management community are being addressed. The results of this survey indicate that the two most important management issues facing coastal programs are land use and habitat change. It is essential that the planning and implementation of the USCOOS take this fact into account and place a priority on addressing these high priority management needs. This can only be accomplished through the direct long-term involvement of the coastal management community with USCOOS efforts at the national and regional levels. …

Potential Of Modis Ocean Bands For Estimating Co2 Flux From Terrestrial Vegetation: A Novel Approach, Abdullah Rahman, Vicente D. Cordova, John A. Gamon, Hans Peter Schmid, Daniel A. Sims

School of Earth, Environmental, & Marine Sciences Faculty Publications

A physiologically-driven spectral index using two ocean-color bands of MODIS satellite sensor showed great potential to track seasonally changing photosynthetic light use efficiency (LUE) and stress-induced reduction in net primary productivity (NPP) of terrestrial vegetation. Based on these findings, we developed a simple ‘‘continuous field’’ model solely based on remotely sensed spectral data that could explain 88% of variability in flux-tower based daily NPP. For the first time, such a procedure is successfully tested at landscape level using satellite imagery. These findings highlight the unexplored potential of narrow-band satellite sensors to improve estimates of spatial and temporal distribution in terrestrial …

Assessing The Efficacy Of Registered Underground Baiting Products For Mountain Beaver (Aplodontia Rufa) Control , Wendy M. Arjo, Dale L. Nolte May 2004

Assessing The Efficacy Of Registered Underground Baiting Products For Mountain Beaver (Aplodontia Rufa) Control , Wendy M. Arjo, Dale L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

The mountain beaver (Aplodontia rufa) is a fossorialrodent species endemic to the Pacific Northwest and portions of California. This herbivore inflicts millions of dollars of damage annually to forest seedling plantations. Currently, extensive trapping prior to planting is the most reliable method for reducing damage. With increasing restrictions placed on trapping, forest resource managers need alternative tools to minimize forest damage. This study assessed the potential of four toxicants registered for underground use to controlmountain beaver; zinc phosphide, diphacinone, chlorophacinone, and strychnine. Zinc phosphide and strychnine are acute toxicants, whereas diphacinone and chlorophacinone are anticoagulants. Anticoagulants prevent the recycling of …

Effects Of Runoff From Downtown Middleboro On The Nemasket River May 2004

Effects Of Runoff From Downtown Middleboro On The Nemasket River

Watershed Access Lab Projects

The Nemasket River Watershed has an area of approximately 7.5 square miles. Historically this river has been used for commerce and transportation, fishing and recreation and, more recently, as a sink for wastewater effluent and urban runoff.

Our investigation was to determine what effects, if any, the runoff from “urban” Middleboro was having on the water quality just downstream from the town center and it’s aquatic life.

Our hypothesis was that the downstream location would be impacted from the increased runoff from the urban setting. The increase in pollution would be due to the increase in imperviousness of the urban …

Restoration And Management Of Gray Wolves In Central Idaho - Progress Report 2003, Curt Mack, Jim Holyan May 2004

Restoration And Management Of Gray Wolves In Central Idaho - Progress Report 2003, Curt Mack, Jim Holyan

Rocky Mountain Wolf Recovery: Annual Reports

The U.S. Fish and Wildlife Service (USFWS) is restoring endangered gray wolves to the northern Rocky Mountains including ongoing efforts in 3 restoration areas: Northwest Montana, the Greater Yellowstone Area, and Central Idaho. Gray wolves naturally recolonized northwest Montana and were down-listed to threatened status under the Endangered Species Act (ESA) in 2003. Nonessential experimental population areas were established for the Greater Yellowstone and Central Idaho Areas where wolves were actively reintroduced under the ESA. This special designation allows for management flexibility to address public concerns such as wolf-livestock conflicts.

In 2003 the USFWS reclassified gray wolves across the lower …


A Study Of Invasive Species Cover Near Roads In A Red Rock Canyon Blackbrush Community, Christopher Keough May 2004

A Study Of Invasive Species Cover Near Roads In A Red Rock Canyon Blackbrush Community, Christopher Keough

UNLV Theses, Dissertations, Professional Papers, and Capstones

The monitoring of Mojave Desert plant communities during and following disturbance is an important process that could provide invaluable information about disturbance/recovery regimes in similar arid environments across the globe. Blackbrush communities are of particular interest because of their low replacement rate, which makes them highly susceptible to disturbance. Roads in the Mojave Desert have been associated with soil compaction resulting in a lack of vegetation as well as an increase in invasive species cover in the immediate proximity. To investigate these statements, eight fifty-foot line transects were established in each of three plot types (perpendicular to dirt roads, perpendicular …


Terrestrial Movements And Habitat Use Of Gopher Frogs (Rana Capito) At Fort Benning, Georgia, Jonathan H. Neufeldt May 2004

Terrestrial Movements And Habitat Use Of Gopher Frogs (Rana Capito) At Fort Benning, Georgia, Jonathan H. Neufeldt

Theses and Dissertations

Gopher frogs (Rana capito) were radio-tracked between the 2000 and 2001 breeding seasons to study their terrestrial movements and habitat use in a longleaf pine- sandhill area on the Fort Benning Military Reservation, Georgia. The telemetry research was conducted in response to the need for biological data concerning gopher frog terrestrial habits. Ultimately the data could aid biologists and land managers in describing critical habitat and the development of a management or recovery plan. Twelve gopher frogs were caught at a herpetofaunal array surrounding two neighboring breeding ponds during a post breeding migration, implanted with miniature transmitters, released and radio-tracked …

West Nile Virus And Wildlife, Peter P. Marra, Sean Griffing, Carolee Caffrey, A. Marm Kilpatrick, Robert Mclean, Christopher Brand, Emi Saito, Alan P. Dupuis, Laura Kramer, Robert Novak May 2004

West Nile Virus And Wildlife, Peter P. Marra, Sean Griffing, Carolee Caffrey, A. Marm Kilpatrick, Robert Mclean, Christopher Brand, Emi Saito, Alan P. Dupuis, Laura Kramer, Robert Novak

United States Department of Agriculture Wildlife Services: Staff Publications

West Nile virus (WNV) has spread rapidly across North America, resulting in human deaths and in the deaths of untold numbers of birds, mammals, and reptiles. The virus has reached Central America and the Caribbean and may spread to Hawaii and South America. Although tens of thousands of birds have died, and studies of some bird species show local declines, few region-wide declines can be attributed to WNV. Predicting future impacts of WNV on wildlife, and pinpointing what drives epidemics, will require substantial additional research into host susceptibility, reservoir competency, and linkages between climate, mosquitoes, and disease. Such work will …
