1Clark, J, L. Horvath, and M. Lewis2001On the estimation of spread rate for a biological population.Clark, J, L. Horvath, and M. Lewis. 2001. On the estimation of spread rate for a biological popularion. Statistics & Probability Letters. 51: 225-234Journal ArticleWe propose a nonparametric estimator for the rate of spread of an introduced population. We prove that the limit distribution of the estimator is normal or stable, depending on the behavior of the moent generating function. We show that resampling methods can also be used to approximate the distribution of the estimators.

2Michelle, B.L., and D.A. Crossley Jr.2000Tullgren extraction of soil mites (Acaria): Effect of refrigeration time on extraction efficiency.Michelle, B.L., and D.A. Crossley Jr. 2000. Tullgren extraction of soil mites (Acaria): Effect of refrigeration time on extraction efficiency. Experimental and Applied Acarology. 24: 135-140Journal ArticleSoil microarthropod constitute one of the most species rich communities in forest ecosystems (Crossley & Glair, 1991). The effects of soil fauna in these systems on decomposition rates, nutrient regeneration and soil structure have been well documented; however, dependable estimates of population size and community structure largely depend upon adequate sampling (Anderson, 1988; Seastedt & Crossley, 1988).

Ecology. 80(6): 1955-1969.Journal ArticleCovergence in interspecific leaf trait relationships across diverse taxonomic groups and biomes would have important evolutionary and ecological implications. Such convergence has been hypothesized to result from trade-offs that limit the combination of plant traits for any species. Here we address this issue by testing for biome differences in the slope and intercept of interspecific relationships among leaf traits: longevity, net photosynthetic capacity (Amax), leaf diffusive conductance (Gs), specific leaf area (SLA), and nitrogen (N) status, for more than 100 species in six distinct biomes of the Americas.

Leaf litter as a source of dissolved organic carbon in streams. Ecosystems. 1: 240-249.Journal ArticleDissolved organic carbon (DOC) is an abundant form of organic matter in stream ecosystems. Most research has focused on the watershed as the source of DOC in streams, but DOC also comes from leaching of organic matter stored in the stream channel. We used a whole-ecosystem experimental approach to assess the significance of leaching of organic matter in the channel as a source of DOC in a headwater stream.

Neutral models: useful tools for understanding landscape patterns, pp. 215-230. In Bissonette, J.A. (ed.), Wildlife and landscape ecology: effects of pattern and scale. Springer, New York.Book ChapterThe purpose of this chapter is to demonstrate their utility in this field of study by discussing how neutral models (1) assist the investigator in understanding patterns in spatial data and (2) are useful for generating maps for quantifying the effort of landscape pattern on ecological processes.
