The relationship between species density and community biomass in grazed and ungrazed coastal meadows
James B. Grace, H. Jutila
1999, Oikos (85) 398-408
Previous studies have indicated that the relationship between community biomass and species density can be represented by a multivariate model in which abiotic variables influence species density both through effects on biomass and through effects on the species pool. In this paper, we use data from grazed and ungrazed coastal...

Thomas J. Stohlgren, L. D. Schell, B. Vanden Heuvel
1999, Ecological Applications (9) 45-64
We used multiscale plots to sample vascular plant diversity and soil characteristics in and adjacent to 26 long-term grazing exclosure sites in Colorado, Wyoming, Montana, and South Dakota, USA. The exclosures were 7–60 yr old (31.2 ± 2.5 yr, mean ± 1 se). Plots were also randomly placed in the...
A GIS modeling method applied to predicting forest songbird habitat
Randy Dettmers, Jonathan Bart
1999, Ecological Applications (9) 152-163
We have developed an approach for using “presence” data to construct habitat models. Presence data are those that indicate locations where the target organism is observed to occur, but that cannot be used to define locations where the organism does not occur. Surveys of highly mobile vertebrates often yield these...
