Site Description
The Jornada Basin Long-Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites funded by the US National Science Foundation (NSF). The Jornada LTER program has been continuously funded since 1982 to develop general principles governing changes between grassland and shrubland ecosystems based on long-term data collected in the Chihuahuan Desert. Research themes at the Jornada LTER focus on vegetation change, climate and land use impacts on ecosystem function, and the role of dryland processes in structuring communities and landscapes. We translate our findings to dryland ecosystems around the world, and forecast the dynamics of future ecosystem states in response to changing ...

Figure 1. Microscale self-segregation of cyanobacterial species in biocrusts.  A Patches attributable to M. vaginatus (dashed white lines) and Parifilum sp. (dashed black lines) on a rehydrated biocrust are visible through differential coloration. Areas sampled for bulk soil (B) and cyanobacterial bundles (A1-4) are indicated by circles. Scale bar is 1 cm. (Nelson et al., 2022)
