Biological Soil Crust Organisms for the Restoration of Disturbed Soils

Biological Soil Crust Organisms for the Restoration of Disturbed Soils

by David Lipson | Jan 12, 2019 | Conservation, MTRP, Research, SMER, Soils

For her M.S. of Ecology, Sharon Reeves did her thesis research on the use of cyanobacteria and algae cultured from biological soil crusts (BSC’s) for restoring disturbed soils. BSC’s naturally occur on the surface of soils in arid and semiarid...
Altered C cycling under exotic annual plant species in a coastal sage scrub ecosystem

Altered C cycling under exotic annual plant species in a coastal sage scrub ecosystem

by David Lipson | Jan 12, 2019 | Global Change, Plant Ecology, Research, SMER, Soils

Coastal sage scrub (CSS) is a semi-arid shrub-dominated ecosystem found in southern California. CSS has been reduced to a tiny fraction of its original extent due to urbanization, conversion to agriculture and degradation by invasive exotic annual plant species. The...
Rainfall Manipulation Experiment at SMER

Rainfall Manipulation Experiment at SMER

by David Lipson | Jan 12, 2019 | Global Change, Plant Ecology, Research, SMER, Soils

We recently completed an NSF-funded rainfall manipulation experiment at Santa Margarita Ecological Reserve. The experiment is investigation the interactive effects of plant functional type (native shrubs vs. exotic annual species) and altered rainfall. This is a...
Elevated CO2 stimulates soil fungal diversity through increased fine root production

Elevated CO2 stimulates soil fungal diversity through increased fine root production

by David Lipson | Jan 12, 2019 | Global Change, Research, Sky Oaks, Soils

In collaboration with the Global Change Research Group (GCRG) and Cheryl Kuske at LANL, we studied the effects of free air CO2 enrichment (FACE) on soil fungal communities in a chaparral ecosystem. We found that elevated CO2 increased root production, which led to an...
