Vegetation dynamics during last 35,000 years at a cold desert locale: preferential loss of forbs with increased aridity

open access: yesEcosphere, Volume 8, Issue 7, July 2017., 2017
Abstract Paleoecological records are an important source of data to better understand ecological responses to climate. To help understand vegetation–climate relationships in the Great Basin cold desert of North America, we analyzed 154 plant taxa from 52 fossil woodrat middens that spanned both an 800‐m elevation gradient and the last 35,000 yr (35 ka)
