A taxonomic review of Rubus L. (Rosaceae) in the Northern Iran based on the analysis of quantitative morphological characters
The genus Rubus is highly variable and frequently occurring in Iran, particularly in North regions. It has a global distribution on all climates except the Antarctic region. Ten morphological quantitative characters in seven species of Rubus in N Iran were studied. Based on the UPGMA cluster analysis of quantitative characters, the similarity of individuals was […]
Genetic structure in anzali wetland’s pike (Esox lucius) using microsatellite molecular method
In this research, Pike (Esox lusius) one of the most valuable commercial marine species has been evaluated for genetic structure in Anzali wetland using microsatellite markers. 60 specimens of adult pikes were sampled from two spawning seasons, winter and spring in Anzali wetland. Five pairs of microsatellites, tested on the genomic deoxyribonucleic acid (DNA). All […]
Morphological variation,cultivation techniques and management practices of Moringa oleifera in Southern Benin (West Africa)
This study examined the phenotypic variation and the modalities for integrating Moringa oleifera in agroforestry systems in southern Benin in order to contribute to sustainable management of the species. Morphological characterization of M. oleifera based on measurements taken on the trees, leaves, leaflets and fruits, and ethno-botanical survey on cultivation techniques and management of plantation […]
Impact of climate on seed morphology and plant growth of Caesalpinia bonduc L. in West Africa
Caesalpinia bonduc L. is an important medicinal plant threatened by overexploitation. In the present study, the impact of climate on seed morphology, germination capacity, seedling and plant growth of C. bonduc were evaluated. A total of 2000 seeds were collected in Sudanian and Guinean climate zones of Africa and their length, width, thickness, weight and […]
Variations in aerial mycobiota of archeological sites of taxila, Pakistan
The transportation of air borne fungal spores to the surface of archeological monuments is very significant step in the process of biodeterioration. The present study was designed to isolate the aerial mycobiota from six world heritage sites of Taxila. The fungal spores were trapped by petri plate gravitational method and three culture media malt extract […]
Typology of cocoa-based agroforestry systems in a forest-savannah transition zone: case study of Kokumbo (Centre, Côte d’Ivoire)
The introduction of hybrid varieties cocoa has led to the progressive disappearance of the complex agroforestry systems in Côte d’Ivoire. However in forests-savannah transition area, these systems seem to persist in despite the high frequency of bushfires, low rainfalls and the change of cocoa trees varieties. To understand the farming practices in that zone, data […]
Heavy metals and nutritional composition of some naturally growing aquatic macrophytes of Northern Egyptian Lakes
Aquatic plants are unchangeable biological filters and they carry out purification of the water bodies therefore, the determination of element compositions in these plants is essential for understanding their nutritive importance. Aquatic macrophytes are known as good indicators of heavy metal contamination in aquatic ecosystems and they act as biological filters by accumulating heavy metals […]
Effects of tropical legume cover crops on soil quality at dryland farming area in Bali, Indonesia
Two field experiments were conducted to study the effects of tropical legume cover crops on soil quality in dryland farming areas at Angantaka village, Badung regency, Bali Province of Indonesia from June to November 2013. In the first experiment, three tropical legume cover crops (LCC) (Centrosema pubescens L.(Cp), Mucuna pruriens L.(Mp) and Pueraria javanica L. […]
Checklist of the opisthobranchs (Heterobranchia: Gastropoda) along the Iranian coasts of the Gulf of Oman
This is the first paper describing the heterobranch fauna of the coasts of Iran. A total of 25 species belonging to 14 families is recorded from the Iranian coasts of the Gulf of Oman. Except for Chromodoris annulata, the remainder are all new records for the area. The families Chromodorididae and Aplysiidae have the highest […]
Influence of soil physicochemical parameters on the abundance of Paracoelophrya polymorphus (Ciliophora: Radiophryidae) commensal of earthworms (Annelida: Glossoscolecidae) collected in Bambui (North-West Cameroon)
Earthworms of the genus Alma nilotica belonging to the family Glossoscolecidae, lodges an abundant fauna of astomatous ciliates in its digestive tract. Each species is located in a well-defined portion of the gut and the reasons for this stratification still remain unclear. In order to assess the influence of physico-chemicals parameters of the soil on […]
