The U.S. National Amphibian Research and Monitoring Initiative and the role of protected areas The U.S. National Amphibian Research and Monitoring Initiative and the role of protected areas
In response to concerns about the worldwide status of amphibians (Alford and Richards 1999; Bury 1999; Daszak et al. 1999; Houlahan et al. 2000), Congress in Fiscal Year 2000 provided initial support to agencies of the U.S. Department of the Interior for research and monitoring of amphibians. Most funds came to the U.S. Geological Survey (USGS), but additional funds for the U.S. Fish and...

Population dynamics and the ecological stability of obligate pollination mutualisms Population dynamics and the ecological stability of obligate pollination mutualisms
Mutualistic interactions almost always produce both costs and benefits for each of the interacting species. It is the difference between gross benefits and costs that determines the net benefit and the per-capita effect on each of the interacting populations. For example, the net benefit of obligate pollinators, such as yucca and senita moths, to plants is determined by the difference...

The importance of competition in regulating plant species abundance along a salinity gradient The importance of competition in regulating plant species abundance along a salinity gradient
Current theories differ in their predictions concerning the effects of interspecific interactions on species growth and distribution along environmental gradients. In this study, we examined the influence of competition on species composition across a salinity gradient. This work involved three common fresh and brackish marsh species. The three species, Spartina patens, Sagittaria...

Interactions between fire and invasive plants in temperate grasslands of North America Interactions between fire and invasive plants in temperate grasslands of North America
A substantial number of invasive grasses, forbs and woody plants have invaded temperate grasslands in North America. Among the invading species are winter annuals, biennials, cool-season perennials, warm-season perennials, vines, shrubs, and trees. Many of these species have been deliberately introduced and widely planted; some are still used for range improvement, pastures, lawns, and...

The roles of community biomass and species pools in the regulation of plant diversity The roles of community biomass and species pools in the regulation of plant diversity
Considerable debate has developed over the importance of community biomass and species pools in the regulation of community diversity. Attempts to explain patterns of plant diversity as a function of community biomass or productivity have been only partially successful and in general, have explained only a fraction of the observed variation in diversity. At the same time studies that...

Species and population variation to salinity stress in Panicum hemitomon, Spartina patens, and Spartina alterniflora: Morphological and physiological constraints Species and population variation to salinity stress in Panicum hemitomon, Spartina patens, and Spartina alterniflora: Morphological and physiological constraints
Panicum hemitomon, Spartina patens, and Spartina alterniflora are wide-spread dominant grasses of fresh, brackish, and salt marsh plant communities, respectively. Our previous research identified significant intraspecific variation in salt tolerance and morphology among populations within each species. In this study our objectives were to determine shorter-term physiological/biochemical...
