statistical studies on palynology contents of late cretaceous to paleocene age gurpi formation in a surface section in zagros basin,sw iran indicate changes in abundance, species diversity, ratio of spiniferites to cyclonephelium (s/c), palynological marine index(pmi) values and organic facies. these palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

agunmukha river is an important water body having plentiful aquatic resources. the fisheries communities in the river are familiar with a diverse range of fishing gear and crafts to catch fish. therefore, the objectives of the present study were to explore fishing gear and fishing crafts, catch composition of the respective gearand identification of fish biodiversity of agunmukha river. a step ...

Snow-fed river Pinder -a tributary of river Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...

Phytoplankton taxa composition of the Caspian Sea were evaluated by using samples collected at 12 stations along the Iranian coast of the Caspian Sea between 1996 and 2010. This study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). The dominant species were the...

the paper claims that the meaning of life in the philosophy of mulla sadra is equivocal (moshakik) and diverse not univocal (motawati). this diversity has its root in mulla sadra’s anthropological view, which states that man is not a single univocal species, but is an equivocal one or a genus including disparate species.  the central issue in this paper is to study the influence of gradual and ...

The genus is distributed throughout the Old World and the Americas, with three distinct regions of diversity: Central and shake the limbs and topic in folk medicine. South America (approx. 500 species), Central Asia and Mediterranean (250 species), Eastern Asia (90 species)various species of the genus salvia are used as Disinfectants, Epileptics Autodigestion, Reduce blood sugar donor, Carminat...

Biological diversity and species richness have been declined throughout the world as a result of human activities. Measuring species richness is important in rangeland conservation to evaluate the status and trends of native plant species, detecting non-native species invasion and monitoring rare species. However, heterogeneity in plant distribution makes inventories difficult. In this study tw...

In this research, biodiversity was investigated in the species diversity level. The objective of this research was to study of Norway Maple (Acer platanoides L.) dispersion and biodiversity of associated woody species in the Shafaroud forests, Gilan (IRAN). In this regard, a 0.5 ha lozenge sample plot was selected with considering presence of Norway Maple in each site. In each plot, geographic ...
