When natural resources are exploited, environmental costs and economic benefits are often asymmetric. An example is apparent in the environmental impacts from fossil fuel extraction by hydraulic fracturing. So far, most scrutiny has been focused on w

The Pine Barrens in New York State are dominated by pitch pine (Pinus ridgida) and scrub oaks (Quercus ilicifolia and Q. prinoides). With fire suppression over the last 90 years or so, P. rigida regeneration has become sparse, even in areas set aside

SUMMARY 1. Extreme hydrologic events are becoming more common with changing climate. Although the impacts of winter and spring floods on lotic ecosystems have been well studied, the effects of summer floods are less well known. 2. The Upper Esopus Cr

Spatially expanding economies threaten the status of basic natural resources. In particular, wildlife habitats rarely benefit. Apart from protected areas, political-economic decision-making is ill-prepared to accommodate wildlife habitats with standa

Applied nucleation is a restoration technique that seeks to facilitate woody-plant establishment by attracting birds or other animals that may introduce seeds of dispersal-limited species. In 1991, an experimental test of applied nucleation was initi

Bunnell et al. (2009) introduced the concept of Stewardship Responsibility (SR) rankings as a tool for conservation planning, using global rankings of rare species in British Columbia. I applied a version of their tool to assess biodiversity distribu

Biodiversity distributions can be quantified as alpha (taxonomic richness), and beta (compositional heterogeneity) components. In both cases, accurate and detailed assessments require substantial resources, so surrogate measures have been proposed an

We compared avian communities and vegetation characteristics in invaded and uninvaded pine barren ecosystems to test whether invasive woody plants were altering native bird communities. We hypothesized that structural changes in vegetation caused by

Studies of forested rural watersheds provide estimates of background contamination for comparison with streams and rivers in other settings. We performed a landscape analysis and measured major dissolved ions and benthic macroinvertebrates for a smal

New York State's fauna is exceptionally rich in odonates (dragonflies and damselflies), whose lengthy aquatic larval phases render them susceptible to effects of lake acidification, including the loss of fish. We used a collection of benthic macroinv
