The Coppermine River in western Nunavut is one of Canada's great Arctic rivers, yet its vascular plant flora is poorly known. Here, we report the results of a floristic inventory of the lower Coppermine River valley and vicinity, including Kugluk (Bloody Falls) Territorial Park and the hamlet of Kugluktuk. The study area is approximately 1,200 km2, extending from the forest-tundra south of the ...

Ata-Kuh forest, a preserved area within Hyrcanian relict forests, with an area of 700 ha is located in north of Iran. Based on floristic studies from 2011 through 2012, 194 vascular plant species were identified belonging to 143 genera and 66 families. Among our samples, 24 taxa were endemic to Hyrcanian area. The largest families in the area were Rosaceae (10.3 %), Poaceae (9.7 %), Asteraceae ...

Recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. Little is known about thevegetation composition of Boralan Mountain region located in North West of Iran in theborder of Turkey and Azerbaijan with the altitude range of 800-2000m. The aim of thisstudy therefore was to investigate the floristic composition qua...

At an altitude of 1664 m, the Col du Noyer in French Dévoluy Mountains, which is accessible summer by road, one most popular Alpine passes. It was located unglaciated area during last Quaternary ice age and suffered effects severe frost. Polygonal grounds formations have recently been discovered. Our study presents results identification characterisation these as well floristic assemblages that...

Vegetation is one of the most important parts of natural ecosystems that in addition to express of the growth conditions, it also shows the influence of ecological factors on the environmental condition. Investigations of plant diversity of a country are necessary for studyingthe ecosystem, pasture, plant gene bank, agriculture and medicine. On the one hand, identification of plant species of d...

AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area floristic divisions in Amazonia. Here we ask whether Amazonian forests are partitioned into broad-scale floristic units on the basis of geological formations a...
