We investigated population characteristics, microhabitat use, and activity patterns of Phrynosoma (Tapaja) douglasii (Pygmy Short-horned Lizard) within shrub-steppe habitat in Washington. Females were significantly larger (and more commonly encounter

Forest seed dispersal is altered after fire. Using seed traps, we studied impacts of fire severity on timing of seed dispersal, total seed rain, and seed rain richness in patches of high and low severity fire and unburned Douglas-fir (Pseudotsuga men

Detrended Correspondence Analysis (DCA) was used on a data set of 112 species from 14 stands dominated by Salix planifolia and/or S. monticola. Environmental variables were determined which might be important to explain differences in stand vegetatio

Salixplanifolia Pursh ssp. planifolia and Salixmonticola Bebb are the dominant willow species of Colorado Rocky Mountain willow carrs. Extensive field observations suggest that neither of these species is capable of sexual propagation under continuou

Seed rain studies provide valuable information for forest researchers monitoring exotic species invasions. Plant species move through forests primarily as seeds, and this dispersal is critical to future forest composition. In this extension note, see
