germination response to temperature is different among plant seeds. germination rate and percentage is maximal at optimum temperature (s), and then reach to zero at base and ceiling temperatures. the objective of this research was (1) to evaluate germination response of snail medic seeds to temperature and (2) to determine cardinal temperatures of germination rate and percentage. therefore, see...

Nearest neighbor spatial analysis was used to assess the effect of systemic rust caused by Uromyces scutellatus on stand density of Euphorbia esula/virgata , a highly invasive deep-rooted perennial weed of rangelands and natural areas in North America. ANOVA applied to nearest neighbor measurements within four pairs of stands in close proximity, with and without rust, in Hungary and Austria ind...

The object of the investigation is to study reducible $M$-ideals in Banach spaces. It is shown that if the number of $M$-ideals in a Banach space $X$ is $n(<infty)$, then the number of reducible $M$-ideals does not exceed of $frac{(n-2)(n-3)}{2}$. Moreover, given a compact metric space $X$, we obtain a general form of a reducible $M$-ideal in the space $C(X)$ of continuous functions on $X$. The...

In South Africa bee stings are most commonly caused by either Apis mellifera capensis or A. mellifera scutellata, indigenous species which are notoriously aggressive when compared to European honey bees. According to Statistics South Africa, 109 deaths were documented for the period 2001-2011 as having been caused by hornets, wasps, and bees (ICD10-X26). This appears to be a small number but, a...

As abelhas africanas (Apis mellifera scutellata) foram introduzidas no Brasil na década de 1950 e, por acidente, cruzaram com outras subespécies melíferas europeias. Isso proporcionou o surgimento híbridos conhecidos atualmente como africanizadas, que possuem características rusticidade e maior capacidade enxamear. A Amazônia mostra potencial para desenvolvimento da apicultura devido suas diver...
