Responses of Typha australis (Schum. & Thonn.) to a cutting of the stem
Typha australis (Schum. and Thonn.) is an invasive species that has grown considerably in northern Senegal. It is increasingly encountered in the Niayes of intensive farming. Typha causes inconvenience to human and the ecosystem. The control of the species is essentially made by cuttings. The results of which are inconclusive. The aim of this study […]
The habitat and estimation population of mamoa bird (Eulipoa Wallacei) in Galela-Halmahera
Mamoa birds (Eulipoa wallacei) is one of endemic bird species in Wallacea. Currently, egg-laying habitat and population of Mamoa was declined by degradation, fragmentation, and eggs harvesting. The aim of the research was to analyze the habitat and estimate the population of Mamoa in Galela North Halmahera. The method used were the combination of transect […]
Determination of population indices and weed distribution map in barley fields of Kermanshah Province, Iran
Weed detection of irrigated barley fields can be considered as the most important strategy for weed management of in this crop. Based on cropping area of barley and frequency of fields in each county of Kermanshah province, barley fields were selected. In order to identify and determine the abundance of weed species in irrigated barley […]
Study of seasonal changes in production and consumption of range plant Artemisia sieberi (Dehno- Kerman Province)
Artemisia sieberi is one of the appropriate forage plants to provide forage for livestock and it is suitable for soil conservation purposes in the steppe rangelands such as rangelands in Dehno (Kerman, Iran). Production and consumption of forage of Artemisia sieberi were carried out for four years. For this purpose, the residual forage after grazing […]
Diversity indices and importance values of a tropical deciduous forest of Chhotanagpur plateau, India
Ecological study was carried out by establishing four one hectare (ha) plots one each in Jiradih (site-I), Chargi (site-II), Sandoi (site-III) and Chiruvabera (site-IV) in December 2012 in the tropical deciduous forest around the Chhotanagpur plateau of Bokaro district, Jharkhand. At each site, 1-ha plot (100 m ˣ 100 m) was demarcated by nylon rope […]
Changes in activity profile of superoxide dismutase in barley cultivars seedling under salt stress
Salt stress is one of the most important factors limiting barley cultivation in arid and semi arid regions. Meanwhile, salt induced production of reactive oxygen species (ROS) induces the activity of some antioxidant enzymes in order to protect plants against stress condition. This study was aimed to investigate the activity of superoxide dismutase (SOD) in […]
Chemical constituents and antibacterial activity of the essential oil from Epilobium hirsutum
Epilobium species have been traditionally used as medicinal plants for centuries. The present work studies the chemical composition and antibacterial activity of the essential oil of Epilobium hirsutum L. from Iran. The essential oil of the aerial parts of the plant was extracted by hydrodistillation method and analyzed by GC and GC/MS. Thirty-two compounds were […]
Morphometric characteristics of Leuciscus cephalus albus (Bonaparte, 1838) (Pisces, Cyprinidae) from Skadar Lake (Montenegro), in the new systematic recognized as Squalius platyceps
Analyses of the morphometric characteristics presented in this manuscript has been done prior Leuciscus cephalus albus change its systematic status to Squalius platyceps. Consequently, data obtained for this white chub population were compared with comparable data for chub populations in aquatic ecosystems in Macedonia, Serbia, Bosnia and Herzegovina and Italy. Out of 27 studied white […]
Study of floristic-ecologic diversity and essential oil variation in Stachys lavandolifolia vahl populations from west of Iran
This study carried out for determination and discrimination of floristic-ecologic and essential oil variation within Stachys lavandolifoliaVahl Populations from west of Iran. In order to study diversity in S. lavandolifolia, D.S.S. method was used. Different stations of S. lavandolifolia were explored and 4 special stations were determined among them. floristic-ecologic data collected from each special […]
