Correlations between environmental factors and wild bee behavior on alfalfa (Medicago sativa) in northwestern China.
To discover the effect of environmental factors on pollinator visitation to flowering Medicago sativa, several field experiments were designed to examine the diurnal movement patterns of wild bee species in the Hexi Corridor of northwestern China. Our study results showed that Megachile abluta, M. spissula, and Xylocopa valga showed unimodal diurnal foraging behavior, whereas Andrena parvula an...
متن کاملNew cold- and drought-regulated gene from Medicago sativa.
Plants are known to differ in their ability to withstand freezing temperatures, but the molecular/genetic basis of this differential freezing tolerance is unclear. Exposure of plants to low, nonfreezing temperatures (cold acclimation) increases their tolerance to subsequent freezing (see recent review by Guy, 1990). Significant biochemical modifications occur during cold acclimation of plants, ...
متن کاملSpecies Delimitation with Gene Flow.
Species are commonly thought to be evolutionarily independent in a way that populations within a species are not. In recent years, studies that seek to identify evolutionarily independent lineages (i.e., to delimit species) using genetic data have typically adopted multispecies coalescent approaches that assume that evolutionary independence is formed by the differential sorting of ancestral al...
متن کاملWind-mediated horseweed (Conyza canadensis) gene flow: pollen emission, dispersion, and deposition
Horseweed (Conyza canadensis) is a problem weed in crop production because of its evolved resistance to glyphosate and other herbicides. Although horseweed is mainly self-pollinating, glyphosate-resistant (GR) horseweed can pollinate glyphosate-susceptible (GS) horseweed. To the best of our knowledge, however, there are no available data on horseweed pollen production, dispersion, and depositio...
متن کاملAbstract Withholding alfalfa (Medicago sativa L.) irri-
Withholding alfalfa (Medicago sativa L.) irrigations during the summer, a practice referred to as summer irrigation termination (SIT), can conserve substantial amounts of water in long-season desert environments; however, plant mortality associated with SIT may be substantial. Proper timing of re-irrigation is critical for minimizing mortality and yield reductions following SIT. Procedures that...
