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 […]
Diversity of ichthyofauna in freshwater system in bega watershed, prosperidad, agusan del sur, Philippines
This study aimed to determine the diversity of the fish species in the freshwater system of Bega watershed, Mabuhay, Prosperidad, Agusan del Sur, Philippines. Sampling was carried out on May 8-14, 2014 using fish net, hand net, spear, and the hook-and-line method. Six species were recorded of which three are endemic, one native, and two […]
Macroepiphytes and macroalgae (Phaeophyceae, rhodophyceae and chlorophyceae) in the nador lagoon (Morocco)
Many species of marine macroalgae support the development of attached communities on their external surfaces, studies on epiphytic algal communities are however rare in lagoonal environments. A major management plan was begun (2014) in the Nador Lagoon and this study was undertaken between 2012 and 2014 to investigate the diversity of the pre-impact epiphytic communities. […]
First record of Genus Bombus Latreille (Hymenoptera: Apidae, Bombini) in Naran Kaghan valley of Pakistan and their floral host range
Five species of the Genus Bombus Latreille (Hymenoptera: Apidae, Bombini) have been reported from the Naran Kaghan valley, KPK province of Pakistan. All of these species has been reported for the first time from this geographical area with their locality records supported by their identification characters and world distribution. Bombus haemorrhoidalis was restricted to altitude […]
Analysis of genetic diversity in bindweed (Convolvulus arvensis L.) populations using random amplified polymorphic DNA (RAPD) markers
Bindweed (Convolvulus arvensis L.) is one of the most harmful weed species in Turkey. Using random amplified polymorphic DNA (RAPD) markers, It investigated the genetic diversity within and among five local populations of bindweed. Fourteen (14) RAPD primers produced a total of 429 bands, of which 142 (33.1%) were polymorphic. The mean Nei’s gene diversity […]
Effects of deficit and normal irrigation with the use of superabsorbents and soil amendments in desert lands of semnan province
This research was aimed to compare normal and deficit irrigation methods and its impact on Atriplex canescens in a desert region of Semnan Province in Iran. In addition, the effect of Stockosorb and Zeolite superabsorbents on water holding capacity in a sandy soil was investigated. According to the obtained results, maximum seedling height (76.33 cm) […]
The influence of climate changes on the hydrobionts
Climate and its changes have a direct impact on the development of the different hydrobiont species. These effects on aquatic organisms could be either positive or negative. Every species adapts specifically to natural periodic and seasonal changes, however, the response to unexpected climate changes is inconsistent and not always adequate. Climate-related factors could influence food […]
The first study of isotomidae fauna (collembola: apterygota) in Lorestan Province, Western Iran, with new records for Iranian fauna
Preliminary fauna of the Isotomidae were investigated in 10 different regions of the Kohdasht County (Lorestan province, Western Iran) during 2013-2014. The specimens were collected from the surface layer of soil and leaf litter. Totally 8 species belonging to 5 genera were found. All species reported for the first time in this province of Iran. […]
