The flora of protected Shanjan rangeland in Shabestar district, Azerbaijan Province, NW Iran was studied using a 1 m × 1 m quadrate in spring and summer 2011. The climate of this area is cold and dry. In this area 94 plant species belonging to 25 families were identified as constituting the major part of the vegetation. The families in the area are Amaryllidaceae, Boraginaceae, Campanulaceae, C...

Turkey has very rich ecosystems and habitats in which various types of vegetation communities and fauna are found. These properties of Turkey depend on its geographical position, different climatic region, mountainous topographical conditions and climatic changes occurred during the Pleistocene. Several field works have been conducted during the period of 1975-2008. The field observations and a...

In most ecosystems, disturbance is an important agent of variation in community structure and composition. Determining the diversity and composition of soil seed bank is essential for designing conservation and restoration programs because it can markedly contribute to future plant communities. Despite the important role of soil seed banks in the composition of different plant communities, and...

Floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. Unique ecological and climatic conditions in the NorthernKhorasan Province (NKP) make it a remarkable habitat for the floristic studies. Plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.Surveys were conducted during active growth per...

MCCUNE, B., and T. F. H. ALLEN. 1985. Forest dynamics in the Bitterroot Canyons, Montana. Can. J. Bot. 63: 377-383. Both shade-tolerant and shade-intolerant tree species may dominate young stands in canyon-bottom forests of the Bitterroot Range. Subsequent dynamics depend on growth characteristics of the colonizing species. Thus, much of the compositional variation arises at stand establishment...

Understanding the recovery dynamics of ecosystems presents a major challenge in the human-impacted tropics. We tested whether secondary forests follow equilibrium or non-equilibrium dynamics by evaluating community reassembly over time, across different successional stages, and among multiple life stages. Based on long-term and static data from six 1-ha plots in NE Costa Rica, we show that seco...

The flora of Xishuangbanna in southern Yunnan, southwestern China, consists of 3340 native seed plant species belonging to 1176 genera and 182 families. Tropical floristic elements at the generic level form a major contribution (78.3%) to the total flora of southern Yunnan, of which the dominant geographic elements are those of tropical Asian distribution. The tropical Asian flora of Xishuangba...
