The goal of this study is to analyze the floristic patterns and the structure of disturbed and undisturbed upland forests, in Permanent Preservation Areas (PPAs) along the Moju river, in the Brazilian state of Pará. Trees with a diameter equal to or larger than 10cm at 1.30m from the ground (DBH) ≥10cm were analyzed for the upper stratum. For the middle stratum, individuals with DBH between 4.9...

The tropical climate in China exists in southeastern Xizang (Tibet), southwestern to southeastern Yunnan, southwestern Guangxi, southern Guangdon, southern Taiwan, and Hainan, and these southern Chinese areas contain tropical floras. I checked and synonymized native seed plants from these tropical areas in China and recognized 12,844 species of seed plants included in 2,181 genera and 227 famil...

In this study, we evaluated the floristic composition of vascular epiphytes in seasonal semideciduous forest fragments of the Itapemirim River basin, Southern State of Espírito Santo, in order to verify its similarity to other semideciduous forests studied in Brazil. Excursions were conducted every fortnight between June 2008 and May 2009, and epiphytes were collected and recorded (55 species, ...

Present paper enumerates highlights of seasonal variation in floristic composition and ecological strategies for the management of ‘Gujar Tal’ at Jaunpur in tropical semi-arid region of eastern U.P. (India). Total composition of macrophytes recorded was 47 from 26 families with maximum 6 plant species of Cyperaceae from April, 2012 to March, 2013 at certain periodic intervals. Maximum number of...

Digital libraries can be regarded as virtual spaces in which collaborative scholarly research can be conducted. Floristic digital libraries provide such collaboration spaces for scientists working on solutions for Earth’s biodiversity problems. However, group awareness and collaboration are not easily achieved in an increasingly distributed environment such as the virtual space in which digital...

Agglomerative clustering, Two Way Indicator Species Analysis (WINSPAN), and Detrended Correspondence Analysis (DCA) were used for the plant community analysis. Remotely sensed data was used as a surrogate in identifying and locating field sites from where floristic composition, environmental and spatial data were collected. Characteristic plant species of each community type are presented toget...

Based on genetic studies and palaeoecological surveys, the main Korean mountain range, the socalled “Baekdudaegan” (BDDG), has been recently suggested to be a major glacial refugium at the Last Glacial Maximum (LGM) for the boreal and temperate flora of northeastern Asia. On the basis of its shared role as a glacial refugium, and on a series of striking similarities in floristic richness and or...

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...
