Psammomys mange clcctivement les tiges et les feuilles salees et succulentes de plusieurs especes de plantes de la famille des Chenopodiacees. Des donnees sur les preferences et les besoins alimentaires de 1'animal sont presentees et notamment sur les quantites qu'il peut ingerer lorsqu'il mange exclusivement soit Suaeda mollis, soit Traganum nudatum, sdit Salsola foetida. Au laboratoire comme ...

The interaction of several biogenic amines and Compound A (2-(4-acetoxyphenyl)-2-chloro- N-methyl-ethylammonium chloride), an analogue of the active substance in a HPLC fraction isolated from the shrub, Salsola tuberculatiformis Botsch., with cytochrome P450c11 was investigated. Noradrenaline, octopamine and Compound A inhibited the type I DOC induced difference spectrum of P450c11 and elicited...

to determine the potential habitat of two rangeland species of salsola rigidaand agropyron trichophorum in qasr-e-shirin, iran, geographic information systems(gis) and remote sensing (rs) techniques were used. at first, several maps (vegetationcover and land uses maps and thematic maps of various organizations) were collected orprepared. for digitizing geology, vegetation and conventional state...

The influence of different concentrations heavy metals (Cu, Mn, Ni, Zn) was analyzed in the Salsola vermiculata germination pattern, seedling development, and accumulation seedlings. responses to were dissimilar. Germination only significantly reduced at Cu Zn 4000 μM but induced radicle growth lower concentrations. Without damage, species acted as a good accumulator tolerant for Cu. In seedlin...

Abstract One basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. Among the but introduced species, Atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. In the current study the effect of chemical competition (allelopathy) of Atriplex canescens o...
