Comparative studies of Indian and Malaysian Thapaocleidus siamensis using molecular marker

In the present communication the sequence of an exotic species of genus Thaparocleidus i.e T. siamensis (Lim, 1990) Lim, 1996 (collected in India) has been compared with that of Malaysian, on in silico basis using 28S rDNA. Since, both are morphologically more or less similar and effect of environment on T. siamensis cannot access structurally. […]

Effect of habitat structure on avian diversity and distribution: the case of main camp, Hwange National Park, Zimbabwe

Bird species distribution is due to preference of certain types of habitats and many birds may disappear if their habitat is destroyed. The vegetation in Hwange National Park has been modified by elephant activity due to their high and growing numbers. An investigation into the influence of habitat structure on bird species distribution was carried […]

Comparison on allowable use of Atriplex leucoclada in Khalij-O-Omani rangelands of Iran

Current research was performed in the selected sites of Khalij-O-Omani vegetative region including Kabkan (Boshehr), Beris (Sistan and Balochestan). Atriplex leucoclada is a key and palatable species, having a considerable portion in rangelands production. For this purpose, 40 similar species of Atriplex leucoclada were selected in each site. Selected species were exposed to different harvesting […]

Genetic diversity among different Crataegus azarolus L. populations using RAPD markers in Iran

The genus Crataegus azarolus L. is well distributed in Iran as a wild plant, with numerous, inherently variable population and genotypes. In flora of Iran this species is divides into tree independent species, while Christensen believed all of them are varieties of C. azarolus. RAPD markers were used to study 12 hawthorn genotypes belonging to […]

Specific behavior of Sitophilus zeamais in the stocks of rice and maize in rural farmers at Bouaflé region, Côte d’Ivoire

Analysis of the array of pests established S. zeamais (Coleoptera : Curculionidae) to be the principal pest which infects rice and maize storages and paves the way for the others insect pests’ infestation. S. zeamais is followed by Tribolium castaneum (Coleoptera : Tenebionidae) and Rhyzopertha dominica (Coleoptera : Bostrichidae). In pure numerical terms with respect […]

Indigenous knowledge of herders for classification and assessment of grazing landscapes in Northern Khorasan, Iran

To conduct this research we selected 42 herder informants known to be most knowledgeable about the local landscapes. The interviews took place at the field survey and the herders’ camps and data were collected during fieldwork using interview, observation and semi-structured questionnaire. We asked the herders of northern Khorasan to study of ‘‘criteria of grazing […]

The dynamics of plankton compositions in juvenile-larvae gut of marble goby fish (Oxyeleotris marmorata Bleeker) collected from Hampalam river and pond in Kapuas Regency, Central Borneo

Appropriate and required feed types are optimally needed to support the viability and growth of Marble Goby Fish (Oxyeleotris marmorata). This research aimed to analyze species, composition, dynamic and density of plankton in gut of Marble Goby juvenile-larvae from Hampalam River and communities’ dykes of Batanjung Village, Kapuas Regency, Central Borneo in 6 stations for […]

Effect of storage conditions and periods of conservation in gene bank on seed viability and germination of Acacia tortilis and Acacia raddiana

In Egyptian deserts, Acacia tortilis trees play an important role for biodiversity and Bedouins populations, where they used as source of animal fodder, timber, fuel wood, charcoal, gums and other products as well as contributing to soil stabilization of sand dunes. This work aimed to study the effect of storage conditions and storage periods of […]

Comparative genetic study among Origanum L. plants grown in Egypt

In the present investigation we focus to study the phylogenetic and chemical variability (essential oil) among four Origanum species under Egyptian condition. Twenty-three components were identified across the four species of genus Origanum. Carvacrol, thymol, p-cymene, and γ-terpinene were found as major components in oils of Origanum vulgaris, Origanum vulgare subsp. Hirtum and Origanum syriacum […]

Litter ants: diversity and composition in Megamalai, Western Ghats

Diversity and composition of litter ants in Megamalai, Western Ghats was investigated in the present study. The study reveals that, tropical evergreen forest has more number of individuals compared to openrock with grassland, tropical moist deciduous forest and tropical dry deciduous forest. The diversity analysis reveals that, the simpson and Shannon diversity indices was higher […]
