Cross-site synthesis project finds new mechanism for grazing effects on plant species diversity

To paraphrase the abstract:

Southwest Field Ecology at the Sevilleta Field Station, New Mexico

Biology 419.004/519.004 (CRN: 24853/24854)

Description: This course will focus on the ecology of the UNM Sevilleta Field Station in the middle Rio Grande Valley. This course is a residential course based at the Sevilleta. Students will be living on‐site for the week in the residences at the Field Station. During this intensive field course, students will be taking field trips and exploring various sites and habitats in central New Mexico. This field‐based class provides a rich opportunity for context‐based learning.
Students will:

Press-pulse interactions, spatial variability and ecological state change

Check out these two recent publications on drivers and indicators of state change and recovery. This is pretty interesting. Although the models and empirical data are mostly from mesic systems, these ideas definitely apply to aridland systems as well.
