PHYTOSOCIOLOGICAL STUDY PDF

Phytosociological structure was studied in limestone mining quarries at Rio Claro, São Paulo, Brazil. Quarries presented a chronosequence, ranging 1 to Intertidal marine, benthic algal, phytosociological studies in Japan have long been done (Taniguti, ; etc.) chiefly on algal zonation and its main regulat-. Phytosociology is the study of plant communities. Phytosociological data consist of the list of species present AND their abundance (coverage) information.

Current World Environment

The aim of the present study was to survey and record the plant species associated with Citrullus colocynthis in different altitudinal localities in the West of Saudi Arabia. Depending on the presence of Citrullus colocynthis L.

Soil samples were collected from the studied localities and the soil properties were investigated. Also, plant species associated phytosociological study C. Phytosociological study studied localities were represented by different ecological, geographical and edaphic sites.

The study revealed of seven types of vegetational association. Prosopis and Acacia were found to be the dominant plants with other plant species.

The dominancy of thorny and little leaf area species mixed with component of dry deciduous and desert forest was observed. Little variation was observed in vegetational characters from site to site. The difference can be due to variation in edaphic characteristics, microclimate and biotic influence Rout and Gupta The concentration of dominance was measured Table 3 by Simpson index Simpson Click here to view table It was highest 0.

It was comparatively less in Panchpadra and Balotra. The low diversity phytosociological study Panchpadra could be due to salinity in sandy soil and dry environment as suggested by Carnell and Orias It may be due to lower rate of diversification of community Fischer and Simpson In Nakoda phytosociological study composition was about 12 species.

Monark reported that diversity tended to increase maximum level if the community is composed of more than 12 to 15 species. In the present study the species diversity was different in each site.

Generally the contagious distribution is common in nature. Random distribution is found only in very uniform environment and Regular distribution occurs where phytosociological study competition exists between the individuals Odum Therefore, the physiochemical nature of phytosociological study environment as well as biological peculiarities of organisms themselves affects patterns of distribution.

Contagious and random distribution was recorded at all the study sites Table 4 but regular distribution was found only in Nakoda area. Contagious distribution in natural vegetation has been reported by several workers Greig and Smith ; Kershau ; Phytosociological study and Yadava Table 5 shows the number of species in quadrats, percentage number of species in each frequency class and comparison with Raunkiares normal frequency class.

These data have also been present graphically in Figure. The nature of vegetation in Balotra was homogenous while in other localities it consists of heterogeneous vegetation. It has been observed that general phytosociological study of Barmer area is mostly heterogeneous. The vegetation of each sites slightly differ by area wise phytosociological study of change in soil strata and surrounding environment.

In Panchpadra the salt is present in sandy soil. Some plants which are dominant in salty soil of Panchpadra which are not present in phytosociological study two sites.

Therefore, the nature of vegetation in Panchpadra is slightly halophytic.
