Competition exclusion, when a single species dominates resources due to superior competitiveness, is seldom observed in nature. Termites compete for resources with deadly consequences, yet more than one species can be found feeding in the same wooden resource. This is especially surprising when drywood species, with colonies of a few hundred, are found cohabiting with subterranean species, with...

The taxonomic status of Reticulitermes Holmgren in North America has been in need of revision for years, but because of morphological ambiguity, traditional morphological identification of Reticulitermes species has always been difficult and unreliable. Analysis of termites, applying non-morphological genetic comparisons of mitochondrial DNA from numerous populations across North America, has i...

abstract treating soil with insecticides is thought to be an effective method for termite control. speed of action and repellency of insecticides are important factors for discussing their barrier effects as soil-treatment termiticide. microcerotermes diversus (silvestri) is the most economically destructive termite in structures in ahwaz region, because the species feed on anything with cellul...

Abstract Background and purpose:Cholera is an endemic disease in Iran and in some cases each year from around the country report. The aim of this study was to evaluate the prevalence of the disease cholera among people suffering from acute diarrhea in the AranvaBidgol. Materials and Methods:In this study, patients with acute diarrhea were examined for cholera detection in the city of AranvaBidg...

Clovers (genus Trifolium) are widely cultivated across the world as forage legumes and make a large contribution to livestock feed production and soil improvement. Subterranean clover (T. subterraneum L.) is well suited for genomic and genetic studies as a reference species in the Trifolium genus, because it is an annual with a simple genome structure (autogamous and diploid), unlike the other ...
