Alternative states and positive feedbacks in restoration ecology.
There is increasing interest in developing better predictive tools and a broader conceptual framework to guide the restoration of degraded land. Traditionally, restoration efforts have focused onExpand
WHAT IS THE OBSERVED RELATIONSHIP BETWEEN SPECIES RICHNESS AND PRODUCTIVITY
Understanding the relationship between species richness and productivity is fundamental to the management and preservation of biodiversity. Yet despite years of study and intense theoreticalExpand
Functional- and abundance-based mechanisms explain diversity loss due to N fertilization.
Human activities have increased N availability dramatically in terrestrial and aquatic ecosystems. Extensive research demonstrates that local plant species diversity generally declines in response toExpand
Sustainable bioenergy production from marginal lands in the US Midwest
Legislation on biofuels production in the USA and Europe is directing food crops towards the production of grain-based ethanol, which can have detrimental consequences for soil carbon sequestration,Expand
Stability and variability in competitive communities.
Long-term variability in the abundance of populations depends on the sensitivity of species to environmental fluctuations and the amplification of environmental fluctuations by interactions amongExpand
Fertilization effects on species density and primary productivity in herbaceous plant communities
Fertilization experiments in plant communities are often interpreted in the context of a hump-shaped relationship between species richness and productivity. We analyze results of fertilizationExpand
Effects of Agronomic Treatments on Structure and Function of Ammonia-Oxidizing Communities
ABSTRACT The aim of this study was to determine the effects of different agricultural treatments and plant communities on the diversity of ammonia oxidizer populations in soil. Denaturing gradientExpand
Linking Ecology and Economics for Ecosystem Management
Abstract This article outlines an approach, based on ecosystem services, for assessing the trade-offs inherent in managing humans embedded in ecological systems. Evaluating these trade-offs requiresExpand
Effects of seed size and growth form on seedling establishment of six monocarpic perennial plants
(1) Effects of seed size and seedling morphology on the establishment of six monocarpic perennials were examined in glasshouse experiments. Both withinand between-species comparisons of seed-sizeExpand
SPECIES RICHNESS IN A SUCCESSIONAL GRASSLAND: EFFECTS OF NITROGEN ENRICHMENT AND PLANT LITTER
We conducted a field experiment in a successional grassland to investigate the short-term effects of nitrogen enrichment and plant litter on plant species richness and on the establishment of aExpand
