GLM versus CCA spatial modeling of plant species distribution
Despite the variety of statistical methods available for static modeling of plant distribution, few studies directly compare methods on a common data set. In this paper, the predictive power of… Expand

Cars, Cows, and Checkerspot Butterflies: Nitrogen Deposition and Management of Nutrient-Poor Grasslands for a Threatened Species
  • S. Weiss
  • Environmental Science, Biology
  • 14 April 1999
Nutrient-poor, serpentinitic soils in the San Francisco Bay area sustain a native grassland that sup- ports many rare species, including the Bay checkerspot butterfly ( Euphydryas editha bayensis ).… Expand

Sun, slope, and butterflies: topographic determinants of habitat quality for Euphydryas editha
Thermal environments in a large, topographically diverse serpentine soil- based grassland were quantified and ranked using a computer model of clear sky insolation and shading on different slopes to… Expand

Landscape scale evaluation of understory light and canopy structure : methods and application in a neotropical lowland rain forest
Light is a key resource controlling tree regeneration in the understory of closed-canopy old-growth forests. To evaluate the distribution of understory light environments at a landscape scale, we… Expand

The theory behind, and the challenges of, conserving nature's stage in a time of rapid change.
Most conservation planning to date has focused on protecting today's biodiversity with the assumption that it will be tomorrow's biodiversity. However, modern climate change has already resulted in… Expand

Effects of abiotic factors on the distribution and activity of the invasive Argentine ant (Hymenoptera: Formicidae)
The Argentine ant, Linepithema humile (Mayr), has spread worldwide, often decimating native ant populations and other arthropod species in invaded areas. It is not known what abiotic and biotic… Expand

Light-transmission Profiles in an Old-growth Forest Canopy:Simulations of Photosynthetically Active Radiation by Using Spatially Explicit Radiative Transfer Models
Light interception is a driving variable for many key ecosystem processes in forests. Canopy gaps, as natural irregularities, are common features of Pacific Northwest conifer forests and have… Expand

Adult emergence phenology in checkerspot butterflies: the effects of macroclimate, topoclimate, and population history
The prediction of adult emergence times in insect populations can be greatly complicated by microclimatic gradients, especially in circumstances where distributions of juveniles along those gradients… Expand
