Greenhouse Gas Inventory Report, Ilonka Zlatar, Cassidee Shinn Oct 2009

Greenhouse Gas Inventory Report, Ilonka Zlatar, Cassidee Shinn

Reports (USI)

National and international organizations and programs like the United States Global Change Research Project and the Intergovernmental Panel on Climate Change agree, and scientific evidence indicates, that anthropogenic greenhouse gas emissions are resulting in global climate change. Unless actions are taken to reverse and reduce the effects of these emissions, future generations will need to either adapt to or bear the burden of the changed environment. Individuals, companies, institutions, municipalities and countries are being called upon during this urgent world crisis. Universities, which support research and education, have a unique opportunity to become leaders in sustainability.

In October 2007, the …


Heat And Smoke Effects On Red Brome Soil Seed Banks, Scott R. Abella, E. Cayenne Engel Oct 2009

Heat And Smoke Effects On Red Brome Soil Seed Banks, Scott R. Abella, E. Cayenne Engel

Public Policy and Leadership Faculty Publications

Management of exotic plants that are annuals entails understanding and managing their soil seed banks. We completed a study of the influences of heat and liquid smoke on red brome (Bromus rubens) soil seed banks collected from Red Rock Canyon in southern Nevada as part of a collaborative fire effects monitoring effort with Bureau of Land Management - Las Vegas. We collected the samples from the 2005 Loop Fire, where we observed in a monitoring field study that exotic grasses such as red brome were relatively sparse in the first 2-3 years (which were during a dry period) following the …

Synthesis Completed Of Post-Fire Recovery Of Native Perennials In The Mojave, Sonoran Deserts, Scott R. Abella Jul 2009

Synthesis Completed Of Post-Fire Recovery Of Native Perennials In The Mojave, Sonoran Deserts, Scott R. Abella

Public Policy and Leadership Faculty Publications

Literature syntheses to develop status of knowledge reports are important to integrate and summarize the scattered scientific literature on a particular topic. The isolation and fragmentation of scientific literature on a topic is not necessarily a shortcoming of science. Rather, it is simply a consequence of having (1) research published in a diverse array of journals, (2) articles build on each other and therefore articles relevant to a particular topic can be published decades apart, and (3) funding virtually impossible to secure to do these periodic assessments of what we know and don’t know (competitive science grants want researchers to …

Colorado College State Of The Rockies Report Card, Walter E. Hecox, Elizabeth L. Kolbe, Matthew K. Reuer Apr 2009

Colorado College State Of The Rockies Report Card, Walter E. Hecox, Elizabeth L. Kolbe, Matthew K. Reuer

Publications (SD)

This year’s Report Card content is largely focused upon wildlife, one of the key natural treasures of the Rockies and a distinguishing aspect to the wildness and beauty we cherish. A related section evaluates the Wild and Scenic River system in the Rockies and how this federal act has protected certain reaches in the West compared to other federal designations and unprotected streams. A key variable for the Rockies’ future is a growing population affecting our natural resources, and in this Report Card we consider the concentration of population growth within large metropolitan areas, a demographic trend known as a …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen Jan 2009

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …

Finicky Fish Finish... Last! On-Site Programming (Grade 5), Discover Mojave: Forever Earth Jan 2009

Finicky Fish Finish... Last! On-Site Programming (Grade 5), Discover Mojave: Forever Earth

Curriculum materials (FE)

In “Finicky Fish Finish…Last!” students explore what has happened to the Colorado River and the reasons why it is so difficult for the razorback sucker to thrive in a changed environment. Working as ichthyologists (fish biologists) at Lake Mead, students collect water quality data such as temperature, pH, and clarity -- to determine whether current habitat conditions are sufficient for survival of young razorback suckers. Students observe and identify non-native fish in Lake Mead as they learn how the razorback sucker interacts with these neighbors. Students assess whether Lake Mead is still a good habitat for razorback suckers. Using the …
