Ecotourism and ecological and conservational importance of Hyrcanian forests are among the most important reasons for studying arboreal species of Hyrcanian forests. The main purpose of this study is to explore genetic diversity of Carpinus orientalis in the study area; north of Iran, by using of morphological and SDS-PAGE of the seed storage proteins patterns. Seed samples were collected from different populations of provinces, Gilan, Mazandaran, Golestan and Khorassan-e-Shomali. The morphological studies performed by 28 characteristics analysis. Seed proteins extracted by Tris-Glycine buffer and then total protein quantified by Bradford assay and protein pattern of the populations was determined by SDS-PAGE technique. Morphological and bands electrophoresis patterns data were analyzed by PAST software. Results showed that, SDS-PAGE electrophoresis pattern of populations have 10 band polymorphisms. The maximum numbers of bands are related to Chalus and Kiasar populations, in the Mazandaran, and minimum numbers of bands are related to Chichal populations, in the Guilan. Resulted clusters from morphological and seed storage protein were different forms. Furthermore, the speed of morphological and genetic changes are not comparable.

The current study concerns biomass estimation of dominant aquatic plant species of four important wetlands in Babol (Mazandaran prov.) namely, Marzoonabad, Bosra, Langoor and Ramenet. 12 plant species belonging to 11 genera and 9 families were surveyed. A total of 131 vegetation plots along seven transects in various wetlands were collected and analyzed by ANOVA tests and DCA ordination. The average biomass of all dominant species in Babol wetlands is 1309.19 gr/m2 of which Phragmites australis and Najas graminea possess the highest and lowest proportions, respectively. Moreover, Typha latifolia and Ceratophyllum demersum with 3029.81 gr/m2 and 330.10 gr/m2 have maximum and minimum dry weight in the studied plots, respectively. In the DCA ordination biplot, species like Ceratophyllum demersum, Typha latifolia, Phragmites australis and Potamogeton pectinatus have remarkable roles in increasing biomass in the studied wetlands. Moreover, ANOVA analyses indicated that except Schoenoplectus lacustris and Potamogeton lucense, other aquatic species demonstrate significant differences among the studied wetlands.
