Effects of disturbance on germination and seedling establishment in a coastal prairie grassland: A test of the competitive release hypothesis Effects of disturbance on germination and seedling establishment in a coastal prairie grassland: A test of the competitive release hypothesis
1. We evaluated the responses of native grassland sods to a variety of types of disturbance in order to assess hypotheses about the competitive effects of established vegetation on seed germination and seedling establishment. In particular, we consider whether germination is more responsive to the magnitude and duration of vegetation removal (competitive release) or to individual...

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...

Identifying determinants of nations' wetland management programs using structural equation modeling: An exploratory analysis Identifying determinants of nations' wetland management programs using structural equation modeling: An exploratory analysis
Integrated management and policy models suggest that solutions to environmental issues may be linked to the socioeconomic and political Characteristics of a nation. In this study, we empirically explore these suggestions by applying them to the wetland management activities of nations. Structural equation modeling was used to evaluate a model of national wetland management effort and one...
