pollen from mesquite (prosopis juliflora) is one of the important causes of immediate hypersensitivity reactions in the arid and semi-arid regions of the world. the aim of present study is to produce and purify the recombinant form of allergenic ole e 1-like protein from the pollen of this allergenic tree. immunological and cross-inhibition assays were performed for the evaluation of ige-bindin...

SUMMARY AUGIST (accomodating uncertainty in genealogies while inferring species tress) is a new software package for inferring species trees while accommodating uncertainty in gene genealogies. It is written for the Mesquite software system and provides sampling procedures to incorporate uncertainty in gene tree reconstruction while providing confidence estimates for inferred species trees. A...

Our objective was to determine if long-term increases in precipitation can maintain grasslands susceptible to desertification, and initiate a reversal of historic regime shifts on desertified shrublands. Perennial grass production and species richness in a multi-year wet period were hypothesized to be greater than expected based on precipitation in a sequence of dry years. These responses were ...
