Species richness and productivity are two fundamental aspects of ecosystems. As a result, the relationship between species richness and productivity has been widely studied. A series of fertilisation experiments in an alpine meadow on the Tibetan Plateau were performed to study the relationship between species richness and productivity. In this paper, we present a novel indicator, i.e., space r...

The disappearance of populations is a prelude to species extinction. No geographically explicit estimates have been made of current population losses of major indicator taxa. Here we compare historic and present distributions of 173 declining mammal species from six continents. These species have collectively lost over 50% of their historic range area, mostly where human activities are intensiv...

The genera Hovadelium Ardoin, 1961 and Mimolaena Ardoin, 1961, endemic in Madagascar, are revised and assigned to the tribe Laenini Seidlitz, 1896 (subfamily Lagriinae Latreille, 1825). New species: Hovadelium ardoini sp. n., Hovadelium bremeri sp. n. and Mimolaena janaki sp. n. An identification key is compiled for all taxa. Distribution of Hovadelium (5 species) and Mimolaena (3 species) is m...

UNLABELLED A cross-sectional molecular epidemiological study of Entamoeba species was conducted among asymptomatic Kenyan children with (n = 123) and without (n = 111) HIV infection. The prevalence of E. histolytica was low (0.4%). Entamoeba species infection was inversely related with HIV infection [HIV(+): 29.3% vs. HIV(-) 55.0%, P < 0.001]: multiple-species infection was related to higher ...

After two major storms, the Swedish Transport Administration was granted permission in 2008 to expand the railroad corridor from 10 to 20 m from the rail banks, and to clear the forest edges in the expanded area. In order to evaluate the possibilities for managers to promote and control the species composition of the woody regrowth so that a forest edge with a graded profile develops over time,...

In this study frequency and composition of plankton in Shadegan wetland was carried out in 5 stations during 2007-2008. Genus qualitative identification and their composition and quantitative frequency aspect were studied (for phytoplankton chlorophyll a). Frequency of total 42 genus phytoplankton in 4 classes Bacilariophyceae (Diatom), Cyanophyceae, Chlorophyceae and Dinophyceae are 69.4, 22.2...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

Previous work by Tesser (1993) and Bourgeois (2002) found that heritable attitudes are more resistant to social influence and attitude change. The present study sought to replicate and extend previous work by utilizing attitudes and heritability estimates not previously used in studies examining the effect of heritable attitudes on social influence processes. It was hypothesized that attitudesw...
