Relevance of macroinvertebrate communities as a water quality monitoring tool in ecosystems under harsh environmental conditions in the Rift Valley region.

Ecological assessment was performed in different thermal springs located in the Ethiopian Rift Valley area: Gergedi, Sodere, Halaba, and Gara. We assessed the habitat conditions, physicochemical characteristics, and macroinvertebrate composition at 12 sampling sites in four thermal spring systems. The physicochemical properties of the water samples varied among the sampling stations.

Phenotypic and Genotypic Characterization of Race TKTTF of Puccinia graminis f. sp. tritici that Caused a Wheat Stem Rust Epidemic in Southern Ethiopia in 2013-14.

A severe stem rust epidemic occurred in southern Ethiopia during November 2013 to January 2014, with yield losses close to 100% on the most widely grown wheat cultivar, 'Digalu'. Sixty-four stem rust samples collected from the regions were analyzed. A meteorological model for airborne spore dispersal was used to identify which regions were most likely to have been infected from postulated sites of initial infection.
