Drylands in the Southwest are inherently water-limited and are undergoing major ecological shifts affecting properties and processes from individuals to populations, and at local to regional scales. These changes can have lasting and, oftentimes, negative effects on ecosystem structure and functioning. This has not only serious implications for the many protected ecological landscapes in the Southwest but also the human societies and economies that depend on them. This session includes research from across the Southwest in the United States and Mexico, and asks how current and future processes at local to global scales are shaped and influenced by the interaction of water availability and the biologic features that define these systems. The session will include a diversity of speakers carrying out research on topics related to abiotic and biotic interactions, ecohydrology, coupled human-ecological systems, land management, resilience in the face of climate change, and more.
