Herbicides And Amphibian Populations, Zach Shirk 2010 University of Nebraska-Lincoln

Herbicides And Amphibian Populations, Zach Shirk

Department of Environmental Studies: Undergraduate Student Theses

Amphibians are a unique class of species that are found worldwide except Antarctica and Greenland. They range in size from a few millimeters to over six feet long. Amphibian’s habitats are as various as their size, but one thing in common is that amphibians require an aquatic location to breed. Amphibians live in deserts, mountain prairies, rain forest, wetlands, and almost everywhere in between. Amphibians are an integrated part of most natural ecosystems across the world. Amphibians are a critical part of many food chains; they provide the important link between secondary and tertiary consumers. Amphibians are indicator species in …

Data Summary From The Tampa Bay Interagency Seagrass Monitoring Program Through Year 2008, Walt Avery, Roger Johansson 2010 University of South Florida

Data Summary From The Tampa Bay Interagency Seagrass Monitoring Program Through Year 2008, Walt Avery, Roger Johansson

Reports

In 1997, the TBEP coordinated the creation of a bay-wide fixed transect seagrass monitoring program. The primary goal of the program is to document temporal and spatial changes in seagrass species composition, abundance, and distribution along a depth gradient. Several bay area agencies committed personnel and equipment to the program. Data collection from 60 transects began in 1998. Currently, 62 transects are monitored due to revisions in transect selection and location. This paper presents a general summary of Tampa Bay seagrass trends from 1998-2008


Assessing The Economic And Environmental Impacts Associated With Current Street Lighting Technologies, Carlos J. Colon Jr. 2010 Air Force Institute of Technology

Assessing The Economic And Environmental Impacts Associated With Current Street Lighting Technologies, Carlos J. Colon Jr.

Theses and Dissertations

Rising global energy demand and natural disasters continuously threaten energy supplies and prices. As a result, the U.S. government has mandated all government agencies to reduce energy consumption in order to minimize dependence on foreign energy supply and reduce costs. Concern over carbon emissions and environmental impacts has also been expressed in these mandates. One solution may be to invest in newer lighting technologies, such as light-emitting diode (LED) and electrodeless induction, in order to reduce the energy consumption, environmental impact, and costs required for both exterior roadway and parking lot lighting applications. This research compared these lighting technologies with …

Blinn, Raymond M. Newman, Dickson M. Atuke, Keith Fredricks, Nathaniel A. Hemstad, Eric Merten, Nicholas Schlesser

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Relatively few evaluations of aquatic macroinvertebrate and fish communities have been published in peer-reviewed literature detailing the effect of varying residual basal area (RBA) after timber harvesting in riparian buffers. Our analysis investigated the effects of partial harvesting within riparian buffers on aquatic macroinvertebrate and fish communities in small streams from two experiments in northern Minnesota northern hardwood-aspen forests. Each experiment evaluated partial harvesting within riparian buffers. In both experiments, benthic macroinvertebrates and fish were collected 1 year prior to harvest and in each of 3 years after harvest. We observed interannual variation for the macroinvertebrate abundance, diversity and taxon …

The Last Days Of Shismaref, Thomas A. Ipri 2010 University of Nevada, Las Vegas

The Last Days Of Shismaref, Thomas A. Ipri

Library Faculty Research

The Last Days of Shishmaref chronicles the lives of several families who live in the eponymous village in northwest Alaska as the effects of global warming begin to decimate their surroundings. This beautifully filmed and meditative documentary focuses on the lives of the Inupiaq Eskimo villagers and does not overtly politicize the often volatile issue of the causes of global warming. The film is more concerned with the effects of climate change rather than the causes.
