Teff [Eragrostis tef (Zucc.) Trotter] is a relatively new forage crop that is attracting much interest among hay growers in the United States and Utah (Creech, et al., 2012). Teff plants have fine stems, shallow roots and are not frost tolerant. This annual, warm-season grass grows best during the hottest months of the year when cool-season grasses suffer their “summer slump.” Since Teff does n...

In the present work 3 names within genus Eragrostis viz, coarctata, E. plana and superba have been typified. Lectotypification has performed for coarctata Second-step lectotypification done superba. For lectotypification, rules recommendations proposed by International Code of Nomenclature algae, fungi plants (ICN), strictly followed. The selection lectotypes are explained images selected provi...

We conducted a study of natural variation in functional leaf traits and herbivory in 116 clones of European aspen, Populus tremula L., the Swedish Aspen (SwAsp) collection, originating from ten degrees of latitude across Sweden and grown in a common garden. In surveys of phytophagous arthropods over two years, we found the aspen canopy supports nearly 100 morphospecies. We identified significan...

In herbaceous ecosystems worldwide, biodiversity has been negatively impacted by changed grazing regimes and nutrient enrichment. Altered disturbance regimes are thought to favour invasive species that have a high phenotypic plasticity, although most studies measure plasticity under controlled conditions in the greenhouse and then assume plasticity is an advantage in the field. Here, we compare...

Knowledge of the relationship between stocking rate or grazing intensity and plant production is fundamental to the sustainable management of rangelands. The general management paradigm is that plant production declines as stocking rate increases. Our objective was to determine the impact of stocking rate on herbaceous production of a sand sagebrush (Artemisia filifolia Torr.)grassland. Stockin...
