Methane (CH4) emissions via emergent aquatic macrophytes can contribute substantially to the global CH4 balance. We addressed temporal variability in CH4 flux by using the static chamber approach to quantify fluxes from plots dominated by two species considered to differ in flux transport mechanisms (Phragmites australis, Carex rostrata). Temporal variability in daily mean emissions from early ...

Restoration efforts take place at large scales to improve the ecological value of degraded, modified river deltas. To anticipate on implications using dredged, estuarine sediment restore wetlands in deltas, we studied development Typha latifolia (cattail) and Phragmites australis (common reed) two designated dredged sediments, virgin Holocene clay (clay) eroded (mud), under different water leve...

روش های مولکولی ابزارهای مهم وقوی در ارزیابی روابط خویشاوندی، تنوع ژنتیکی و شناسایی گونه های گیاهی می باشد. مهمترین توالی های مولکولی برای مطالعات فیلوژنتیکی در سطوح جنس و گونه ناحیه its ژن های dna s26 –s 8/5 –s 18 ریبوزومی هسته می باشد. از نکته نظر تاکسونومیکی یک مشکل بزرگ این جنس خویشاوندی نزدیک بین گونه هاست و بیشتر آنها به وسیله ی فرم های حدواسط که احتمالا منشا هیبرید دارند ابهام دار هستند....

in last decades, oil spill pollution has become an important issue of concern due to its serious environmental impacts; therefore, necessary actions should be taken to prevent or reduce these types of pollution and their environmental consequences. natural organic sorbents are emerging as proper choices for oil spill cleanup due to their availability, eco-friendliness, and low cost. in this stu...

Understanding changes in the interactions between parasitic plants and their hosts in relation to ontogenetic changes in the hosts is crucial for successful use of parasitic plants as biological controls. We investigated growth, photosynthesis and chemical defences in different-aged Bidens pilosa plants in response to infection by Cuscuta australis. We were particularly interested in whether pl...

UNLABELLED PREMISE OF THE STUDY Bathysa australis is a common subcanopy tree from the Atlantic Forest that is pollinated by bees and wasps and produces autochoric seeds. This species exhibits great phenotypic plasticity along the elevational gradient of Serra do Mar in southeastern Brazil. We expect to assess the genetic diversity and gene flow between populations of this species along the e...

Intra-specific variability of root biomass production (RP) of six rooted macrophytes, i.e. Juncus effusus, Phragmites australis, Schoenoplectus lacustris, Typha latifolia, Phalaris arundinacea, and Iris pseudacorus grown from clones, in response to Cu exposure was investigated. Root biomass production varied widely for all these macrophytes in control conditions (0.08 μM) according to the sampl...
