A conservation assessment of the herpetofauna of a moist semi-deciduous forest in Ghana
A conservation assessment of amphibians and reptiles was undertaken in the Gyemera Forest Reserve (GFR) and Gyeni River Forest Reserve (GRFR) in the Moist Semi-deciduous forests of the Amansie West District of the Ashanti Region of Ghana. Refuge examination, acoustic searches, pitfall trapping and interviews were employed in data collection at the study sites. Forty […]
Effect of physiographic factors on the distribution of wild Almond (Amygdalusorientalis Mill) in West of Iran
Habitat needs and requirement of important species in terms of distribution is necessary for natural resources management. Amygdalusorientalisis one of the forest species in west of Iran for food, industries and environmental protection in different climatic conditions.In this research, the effect of physiographic factors such as land form, aspect, altitude and slope on qualitative and […]
Lignocellulolytic activities of crude gut extracts of marine woodborers Dicyathifer mannii and Sphaeroma terebrans
Marine woodborers have a close association with tropical mangrove plants whereby they voraciously consume lignocellulose and play a role in nutrient cycling. They represent a rich source of potential lignocellulolytic enzymes that can be harnessed for conversion of biomass into simple sugars and other monomers for a variety of uses. Ligninolytic enzymes find applications in […]
Interrelationships between morphometric variables and total weight in male fish Chondrostoma regium (Heckel, 1843) evaluated by path analysis in Ghamasiab river Kermansha, Iran
The objective of this study was to verify which morphometric measures and their ratios are more directly associated with the Total weight yields in male fish of Chondrostoma regium. A total of 153 samples of male fish (Chondrostoma regium) from Ghamasiab River with average total weight of 73.47 g ± 2.81 g. were sampled, weighed, […]
Biodiversity and distribution of freshwater molluscs in superficial waters of Ouergha watershed (Morocco)
The primary goal of this work was to establish the specific biodiversity of freshwater molluscs in aquatic environments of Ouergha watershed. This faunal inventory fills the gaps in inventories malacological of Morocco especially the malacofauna of high altitudes. The missions surveys conducted between 2002 and 2005 show that the species found in the catchment area […]
Investigation on potential of Suaeda fruticosa as a source of edible oil
Given the extent of saline lands in Iran, cultivation and utilization of halophytes and salt tolerant species under the condition that both water and soil are saline could be a viable option in production and extraction of vegetable oils from halophytes and salt tolerant species.The aim of this study was to investigate the potential of […]

Effect of plant hormones on callus induction of explant types in endangered medicinal herb Tashnedari
Tashnedari endangered medicinal with Scrophularia striata scientific name is native to Iran and its main habitat is Ilam province. In order to callus induction in this plant species two separate factorial experiment as completely randomized design with three replications was performed in Sari agricultural sciences and natural resources university biotechnology laboratory in 2012. Explants were […]
Effects of recreational activities on some stand parameters and biodiversity indicators in Fandoghlou forests, Northwestern Iran
In the current study, the impacts of different intensities of small-scale recreational activities, including no-impacted, slightly impacted, moderately impacted and severely impacted, were analyzed on some stand parameters and forest biodiversity indicators. The study was conducted in the Fandoghlou forest ecosystem in Northwestern Iran. Data was collected by a set of 120 circular plots with […]
Propagation of Pentaclethra macrophylla Benth (Fabaceae) through seed and rooting of leafy stem cuttings
We assessed a number of factors controlling seed germination and rooting success of leafy stem cuttings of a high priority fruit (food and medicine) tree species from West and Central Africa, i.e. Pentaclethra macrophylla Benth (Fabaceae). In the case of seed germination, we tested three substrates (soil, sand, and a mixture of soil + sand […]
