Identifying the Impact of Biotic Interactions on Meadow Species Distributions in Sagebrush and Bunchgrass Dominated Systems
Abstract
Understanding drivers of species distributions is an important challenge for more accurately projecting ecological change under climate warming. Species distributions have often been modeled using solely environmental factors as predictors. However, there is much recent data supporting the hypothesis that biotic interactions strongly influence species distributions at both local and global scales. This study aims to provide data on how existing plant communities alter the realized ranges of other species. By comparing species distribution model (SDM) predictions with field observations, we analyzed the effects of two taxa of dominant plant cover, sagebrush and a Fescue bunchgrass, upon the distributions of ~20 different herbaceous meadow species in a subalpine valley in western Colorado. This data will add to our understanding of how plant community dynamics interact with observed distributions across scales.
