SAVANNA LAB

The whole world is a savanna; forests and grasslands are just special cases

Welcome! The Savanna Lab (lab members) at New Mexico State University studies the structure, function, and ecology of arid ecosystems, including the shrublands and grasslands of the Northern Chihuahuan Desert, the grazing lands and savannas of Africa, and the other temperate and tropical drought-seasonal systems of our globe (our research). Our research spans diverse spatial and temporal scales, ranging from detailed plot-based experimentation, to landscape-scale observations, and finally reaching regional and global scale remote sensing and modeling. We are interested in fundamental ecological theory for arid ecosystem function, applications in grazing land sustainability and pastoral livelihoods, and the implications for global biogeochemical cycles, climate change and land surface-climate interactions (our publications).

Title: A Multiscale Analysis of Termite Mounds in Ecosystems
Time/Date: March 14th at 1:00 pm MST
Where: Zoom
Brianna Lind has documented nearly 72 million termite mounds across Senegal, West Africa, and her research reveals the potential of termite mounds to affect water redistribution and plant growth at local and ecosystem scales. Flyer Link.

               

New review paper evaluates the role of drylands in future climate change mitigation plans

November 11 2021

Frontiers in Environmental Sciences has just published a new article for COP26. In this article, Niall Hanan and other colleagues reviewed the current literature and found there is a globally significant amount of carbon stored in drylands. Future management of dryland carbon will need to consider local ecological contexts that can enhance carbon in vegetation and in soil organic and inorganic carbon, while ensuring ecological integrity of dryland systems and provision of critical services to dryland populations.

 

New drylands specialty section open for submissions in Frontiers in Environmental Science

August 06 2021

Frontiers in Environmental Sciences have launched a new specialty section “Drylands” with Niall Hanan, and several Savanna Lab members and colleagues from around the world serving on the Editorial Board. The Drylands section brings together interdisciplinary research focused on global drylands, including tropical and temperate, high latitude and high elevation deserts, savannas, grasslands and related arid, semi-arid and drought-seasonal environments.
