TLDR
In this article, the authors discuss the importance of plant litter cover in succession among annual weed species in rangeland communities, including downy brome (Bromus tectorum L.) and medusahead (Taeniatherum asperum (Sim.) Nevski).Abstract:
Plant litter that covers the soil surface acts as a layer of insulation moderating temperature and moisture, and creating favorable microsites for germination and the establishment of annual weed species in rangeland communities. Litter cover is an important factor in succession among annual species which culminates in dominance by downy brome (Bromus tectorum L.) and medusahead (Taeniatherum asperum (Sim.) Nevski) in these communities.read more

Biological invasions by exotic grasses, the grass/fire cycle, and global change
TL;DR: Biological invasions into wholly new regions are a consequence of a far reaching but underappreciated component of global environmental change, the human-caused breakdown of biogeographic barriers to species dispersal.

Plant litter : its dynamics and effects on plant community structure
TL;DR: The existing evidence shows that only tolerance to litter accumulation admits adaptative value as the most likely explanation, and the direct and indirect effects of plant litter on plant populations and communities are discussed.

The Role of Competition in Plant Communities in Arid and Semiarid Regions
TL;DR: This paper reviews the available evidence for competition in plant communities in arid and semiarid regions and demonstrates that competition certainly occurs in these communities and involves many different species; in several instances it appears to be important in the determination of community structure.

Functional Matrix: A Conceptual Framework for Predicting Multiple Plant Effects on Ecosystem Processes
TL;DR: A new theoretical framework is presented, the functional matrix, which builds upon the functional group and single trait approaches to account for the ecosystem effects of multiple traits that vary independently from one another.

Physiological Ecology of North American Desert Plants
TL;DR: In this paper, the physical and biological characterization of the four North American deserts and a description of the primary adaptations of plants to environmental stress are described, along with a synthesis of the adaptations and resource requirements of North American desert plants.

Germination Behavior of Salsola as Influenced by Temperature, Moisture, Depth of Planting, and Gamma Irradiation1
TL;DR: Evidence obtained with gamma irradiation from a Co/sup 60/ source indicates that germination consists of rapid cell elongation in response to moisture and that new cell division is not necessary to the process.
