A multivariate analysis of morphometric data suggests that the nominally pleioxenous ectoparasite, Androlaelaps rotundus, includes at least three distinct host-associated populations in Paraguay. Where multiple akodontine hosts occur sympatrically, each host species is accompanied by a morphologically distinct mite population. These host-mite associations were consistent across all localities, ...

Summary The name Cyperus atronervatus subsp. angustifolius was not validly published due to the omission of a Latin diagnosis. is here.

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...

Cyperus platycaulis is used in folk medicine in Kano, northern Nigeria, for the treatment of cold, cough, (tuberculosis), chest congestion, asthma, sneezing, and catarrh. The tuberous fragrant herb (black species) was extracted using ethanol, chloroform, n-butane, and n-hexane, to determine the physico-chemical properties of the plant and the cytotoxicity of the extracts with reference to its a...

We determined the prevalence of Sin Nombre virus antibodies in small mammals in southeastern Arizona. Of 1,234 rodents (from 13 species) captured each month from May through December 1995, only mice in the genus Peromyscus were seropositive. Antibody prevalence was 14.3% in 21 white-footed mice (P. leucopus), 13.3% in 98 brush mice (P. boylii), 0.8% in 118 cactus mice (P. eremicus), and 0% in 2...
