Grazing effects on grassland ecosystems

Publications Posted on: July 26, 2010
In this study, we used a modified version of a meta-analysis (compilation and analysis of the literature in which an individual area is subjected to the disturbance and its response is noted) to analyze grazing effects on grassland ecosystems. Prior efforts have focused on one aspect of ecosystem behavior such as productivity or species diversity.

Geographic overview: Climate, phenology, and disturbance regimes in steppe and desert communities

Publications Posted on: July 26, 2010
In midwestern steppes, precipitation peaks in summer, whereas west of the Rocky Mountains, steppes are characterized by summer drought. In western deserts, the amount of precipitation is highly variable. These different climatic regimes result in differences in prevalence of and resilience to disturbances such as herbivory, and differences in susceptibility to invasion by exotic plants and animals.

Sustaining western grasslands and associated wildlife: An introduction

Publications Posted on: July 26, 2010
This publication is the result of a half-day symposium, "Ecology, management, and sustainability of western grassland ecosystems," held at The Wildlife Society’s First Annual Technical Conference, September 22-26, 1994 in Albuquerque, NM. The symposium was sponsored by The Wildlife Society's Working Group on Sustainable Use of Ecosystem Resources and was organized by members Deborah Finch, Gale Wolters, and Bertie Weddell.

Recovering southwestern willow flycatcher populations will benefit riparian health

Publications Posted on: July 19, 2010
When the U.S. Fish and Wildlife Service (USFWS) listed the southwestern willow flycatcher (Empidonax traillii exigua) as federally endangered in 1995, new incentives, controversies and energy were generated to conserve and restore southwestern riparian ecosystems. Close attention has been focused on river and stream conservation in the Southwest since at least 1977, when the U.S.

Introduction to the featured collection on riparian ecosystems and buffers

Publications Posted on: June 16, 2010
Riparian ecosystems, located at the interface of terrestrial and aquatic systems, are often given special attention by scientists for their high biodiversity and biological activity (Naiman et al., 1993; Naiman and Decamps, 1997) and significant role in nutrient and energy flux (McClain et al., 2003). Riparian ecosystems are known to buffer environmental impacts and contribute to the maintenance of water quality (Lowrance et al., 1997).

Desired future conditions for Southwestern riparian ecosystems: Bringing interests and concerns together

Publications Posted on: December 13, 2006
This proceedings represents scientific and applied papers presented at a symposium of the same title held 18-22 September 1995 at the Four Seasons Hotel in Albuquerque, New Mexico. The symposium brought together scientists, natural resource managers, conservationists, and representatives from the private sector to share their findings, ideas, and visions for managing, conserving, and restoring riparian ecosystems in the Southwest.

Riparian ecosystems and buffers - multiscale structure, function, and management: introduction

Publications Posted on: July 06, 2006
Given the importance of issues related to improved understanding and management of riparian ecosystems and buffers, the American Water Resources Association (AWRA) sponsored a Summer Specialty Conference in June 2004 at Olympic Valley, California, entitled 'Riparian Ecosystems and Buffers: Multiscale Structure, Function, and Management.' The primary objective of the conference was to provide a forum for the presentation, exchange, and discussi

Effects of land use practices on western riparian ecosystems

Publications Posted on: May 17, 2006
Riparian ecosystems are among the rarest and most sensitive habitat types in the western United States. Riparian habitat is critical for up to 80% of terrestrial vertebrate species, and is especially important in the arid West. Estimates have placed riparian habitat loss at greater than 95% in most western states. Impacts to riparian ecosystems are reviewed along with mitigation and conservation recommendations for resource managers.

Publications Posted on: May 17, 2006
Description of the system: Bottomland hardwood forests (including bald cypress and tupelo swamp forests) are historically the dominant natural community of riverine floodplains of the southeastern United States.
