Environmental Niche Dynamics of Blue Grama () Ecotypes in Northern Mexico: Genetic Structure and Implications for Restoration Management.

Understanding the genetic structure adopted by natural populations and its relation to environmental adaptation is critical for the success of restoration programs. We evaluated the genetic structure and temporal environmental niche dynamics of blue grama () in 48 populations. The genetic evaluation was performed through amplified fragment length polymorphism (AFLP) molecular markers.

Soil nitrate nitrogen dynamics after biosolids application in a tobosagrass desert grassland.

Dormant-season application of biosolids increases desert grass production more than growing season application in the first growing season after application. Differential patterns of NO3-N (plant available N) release following seasonal biosolids application may explain this response. Experiments were conducted to determine soil nitrate nitrogen dynamics following application of biosolids during two seasons in a tobosagrass [Hilaria mutica (Buckl.
