BACKGROUND Deforestation is one of the most ubiquitous forms of land degradation worldwide. Although remote sensing and aerial photographs can supply valuable information on land/use cover changes, they may not regularly be available for some tropical coasts (e.g., Cameroon estuary) where cloud cover is frequent. With respect to mangroves, researchers are now employing local knowledge as an alt...
Plant community composition can impact ecosystem processes via litter feedbacks. Species variation in litter quality may generate diff erent patterns of nutrient supply for plants that are dependent on litter inputs. However, it is not known whether plants grow faster in their own litter, litter from other species, or in litter mixtures from multiple species. To test whether litter identity and...
Background and Objectives: Diabetes Mellitus is a major endocrine disorder and growing health problem in most of countries. Avicennia marina is a type of mangrove plants which can grows in the Iranian coastal areas of Persian Gulf. We studied the effects of Avicennia marina leaves aqueous and hydroalcoholic extract on streptozotocin -induced diabetic male rats. Material and Methods : In thi...
This study was conducted to identify suitable sites for planting Avicennia marina in Soltani Khore of the urban coast of Bushehr. The most effective criteria for Avicennia marina planting include land characteristics (i.e. land use, slope, elevation, soil electrical conductivity, soil texture, and soil type), seawater (i.e. tidal range, wave, acidity, electrical conductivity, and salinity), and...
Background and purpose: Avicennia marina (family Acanthaceae) has been used as traditional medicine in Iran to treat some diseases such as ulcers, rheumatism and burns. The present study investigated the in silico and in vitro mutagenicity of the fruit, leaf, seed and stem extracts of Avicennia marina and their effects on human peripheral blood mononuclear cells (PBMC) proliferation. Materia...

Leaf gas exchange was assessed in Avicennia germinans L. grown under different NaCl concentrations (0-40 per thousand), after salt-relief, and then during drought. Stomatal conductance (gs) and net photosynthetic rate (Pn) decreased with increasing NaCl concentration, and intrinsic water use efficiency (Pn / gs) increased. Under desalinization Pn / gs declined. Thus, gs did not change in plants...
Although knowledge on dispersal patterns is essential for predicting long-term population dynamics, critical information on the modalities of passive dispersal and potential interactions between vectors is often missing. Here, we use mangrove propagules with a wide variety of morphologies to investigate the interaction between water and wind as a driver of passive dispersal. We imposed 16 combi...
در این مطالعه تجمع فلزات نیکل (ni) و وانادیوم (v) در رسوبات، ریشه و برگ رویشگاه های مانگرو (avicennia marina) و میزان انتقال آنها از رسوب به ریشه و برگ در خلیج نایبند و جزیره قشم مورد بررسی قرارگرفت. نمونه برداری به صورت تصادفی سیستماتیک با استفاده از ترانسکت های انتخابی در 16 ایستگاه در منتهی الیه سمت خشکی و دریا در دو رویشگاه با سه تکرار از رسوب، ریشه و برگ درختان مانگرو انجام شد. خصوصیات بست...
Four new jacaranone analogs, marinoids F-I (1-4), were isolated from the fruits of a Beibu Gulf mangrove Avicennia marina. The structures were elucidated based on analysis of spectroscopic data. Marinoids F and G are shown to be diastereoisomers of chlorocornoside, a new halogen containing marine secondary metabolite. The antioxidant activity of the isolates was evaluated using a cellular antio...
