What landscapes best represent the land uses and land covers (LU/LC) of the continental United States? Would the set include a cornfield? A forest? A backyard? Combining principles of landscape ecology and computer science, we identified a small set of âexemplar landscapesâ, representing distinct LU/LC pattern types of the conterminous US. We first partitioned the 1992 US National Land Cover Dataset into 193 705 landscapes, and quantified patterns with standard measures of LU/LC composition and configuration.

Many carbon dioxide (COâ) emissionâreduction strategies currently under consideration rely on terrestrial carbon (C) sequestration to offset substantial proportions of COâ emissions. We estimated C sequestration rates and potential land areas for a diverse array of landâcover changes in the Upper Midwest of the US, a âbest caseâ region for this study because of its relatively modest COâ emissions and the large areas of cropland potentially available for conversion.

Many ecosystems are influenced by disturbances that create specific successional states and habitat structures that species need to persist. Estimating transition probabilities between habitat states and modeling the factors that influence such transitions have many applications for investigating and managing disturbanceâprone ecosystems. We identify the correspondence between multistate captureârecapture models and Markov models of habitat dynamics.

Environmental and ecological research has long been characterized as operating along a continuum, with âbasicâ â representing âinvestigatorâinitiatedâ research â at one end and âappliedâ â representing âmissionâinitiatedâ research â at the other. While federal agency science programs ideally occupy points along this continuum, the resulting science has not always been relevant to solving environmental problems.

Spatially organized distribution patterns of species and communities are shaped by both autogenic processes (neutral mechanism theory) and exogenous processes (niche theory). In the latter, environmental variables that are themselves spatially organized induce spatial structure in the response variables. The relative importance of these processes has not yet been investigated in urban habitats.
