The genus Carex belongs to tribe Cariceae, subfamily Caricoideae and family Cyperaceae. This genus, with about 2000 species in the world and more than 50 species in Iran, is the largest genus among the family. In expedition to North West and West of Iran, two species, namely, Carex acuta and C. cilicica as new records and C. flava, C. rostrata and C. supina as reinvestigated species are reporte...

The present article describes the heavy metal content (Ni, Pb, Cd) in top plant phytomass: blue marsh bog (Eleocharis palustris (L.) Roem. Schult.), furcular Anemonidium (Anemonidium dichotomum Holub), bayonet rush (Juncus filiformis L.), vetchling (Lathyrus carex acuta (Carex reed canary grass (Phalaroides arundinacea clump speedwell (Veronica longifolia silverweed cinquefoil (Potentilla anser...

Plants of the Carex genus (Family: Cyperaceae) have attracted recent attention as potential food additives due to their high levels of potential bioactive compounds. In this study, the stilbene contents of five unexplored Carex species were investigated: Carex capillacea, Carex hirta, Carex buchananii, Carex cuprina, Carex glauca. High-performance liquid chromatography coupled to mass spectrome...

Wide speculation surrounds the origin and phylogenetic relationships of the most highly reduced sections in the genus Carex. In order to gain a better understanding of phylogeny in Carex, the relationship of the reduced sect. Phyllostachys to 12 putatively related sections, representing all four subgenera (Primocarex, Indocarex, Carex, Vignea), was inferred from sequences of the ITS (internal t...

The article presents information on floristic findings in the Kabardino-Balkari Republic. As a result of expedition research 2020-2021 and inventory studies Herbarium Tembotov Institute Ecology Mountain Territories RAS, we revealed nine species new to Kabardino-Balkar Republic locations ten vascular plants species. Species region flora were Carex acuta , Genista angustifolia Amorpha fruticosa A...

REZNICEK, A. A. 1990. Evolution in sedges (Carex, Cyperaceae). Can. J. Bot. 68: 1409-1432. Carex is the largest and most widespread genus of Cyperaceae, but evolutionary relationships within it are poorly understood. Subgenus Primocarex was generally thought to be artificial and derived from diverse multispicate species. Relationships of rachilla-bearing species of subgenus Primocarex, however,...

The sewage snail Physa acuta is a serious threat to certain economic plants and to the purification plant of sewage works by rendering the biofilters ineffective. Various attempts are being made to control it. The efficacy of the predacious water bugs Sphaerodema rusticum was judged experimentally, in the laboratory in the potential control of P. acuta. It is revealed that, when supplied separa...

Indirect facilitation occurs when the indirect positive effect of one species on another, via the suppression of a shared competitor, is stronger than the direct competitive effect. Although theory predicts that these interactions may be common in assemblages of three or more competitors, experimental studies of this process are rare. Here, I report a study of a northern California riparian com...
