C4 plants use the C4 carbon fixation pathway to increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and… The use of more than 100 song playback experiments reveals that birds give stronger responses to songs of closely related species in the Amazon than in temperate North America, suggesting that speciation is currently happening more slowly… Ecology Letters 8: Foster, B. L., V. H. Smith, T. L. Dickson, and T. Hildebrand Invasibility and compositional stability in a grassland community: relationships to diversity and extrinsic factors. Vegetation response to nutrient addition can vary across space, yet studies that explicitly incorporate spatial pattern into experimental approaches are rare. To explore whether there are unique spatial scales (grains) at which grass… The impact of productivity on species diversity is often studied at small spatial scales and without taking additional environmental factors into account. Focusing on small spatial scales removes important regional scale effects, such as… The rapid global plant diversity and productivity loss has resulted in ecosystem functional degeneration in recent decades, and the relationship between plant diversity and productivity is a pressing issue around the world.

Ecology Letters 8: Foster, B. L., V. H. Smith, T. L. Dickson, and T. Hildebrand Invasibility and compositional stability in a grassland community: relationships to diversity and extrinsic factors.

For centuries, biologists have studied patterns of plant and animal diversity at continental scales. Until recently, similar studies were impossible for microorganisms, arguably the most diverse and abundant group of organisms on Earth.

17 Feb 2006 Community ecology is the study of a set of species co- occurring at a given time and place. MacArthur suggested that the goal of community ecology (as of us: Brian Maurer, Gary Mittelbach and Mike Rosenzweig. We also poorest countries to gain free access to biomedical literature through the Internet.

Grazing extensification and intensification are among the main problems affecting European grasslands. We analyze the impact of grazing intensity (low and moderate) and the use of veterinary medical products (VMPs) on the dung beetle…

In addition, and also in contrast to plant restoration ecology, the community context for a predator tends to be usefully conceptualized around trophic interactions first and foremost. Publications Authored by Zhu Kai At the population-level, biologists often interpret negative D M relationships as evidence of density-dependent survival or as models of ecosystem carrying capacity (i.e., the ‘self-thinning rule’)4,5.

Grazing extensification and intensification are among the main problems affecting European grasslands. We analyze the impact of grazing intensity (low and moderate) and the use of veterinary medical products (VMPs) on the dung beetle… Arthropod community structure (based upon 18 response variables) diverged over time between Supplemented and Ambient treatments, with no effect of Fencing on the multivariate response pattern.

Background Assemblage responses to environmental gradients are key to understand the general principles behind the assembly and functioning of communities. The spatially and temporally uneven distribution of water availability in drylands… In the past decade, significant efforts have been made to describe fish-habitat associations. However, most studies have oversimplified actual connections between fish assemblages and their habitats by using univariate correlations.
