Interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. To protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. As main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. Ecologically, functional parameters such as stab...

According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...

The larvicidal activities to determine the efficacies of acetone, ethyl acetate, chloroform and butanol dried leaf extracts of Annona squamosa, Cynodon dactylon, Melia azedarach and root extract of Hemidesmus indicus tested against 3 instar Culex quinquefasciatus and Aedes aegypti. The highest larvae mortality was found in the acetone followed by ethyl acetate, chloroform and butanol extract of...

Background and Objective: Depression and epilepsy are considered as the strongest predictor of poor quality of life. A complex relation has been established between the two conditions which suggest that the high co morbidity of depression and epilepsy is related to the existence of common neurobiologic and pathogenic mechanisms involved in them. Plants and their extracts are better choice to tr...

South African savanna grasslands are often characterised by indigestible tufted grass species whereas lawn grasses are far more desirable in terms of herbivore sustenance. We aimed to investigate the role of nutrients and/or the disturbance (grazing, trampling) by herbivores on the formation of grazing lawns. We conducted a series of common garden experiments to test the effect of nutrients on ...

Allelopathic effects of aqueous extract of rhizomes of  Cynodon dactylon L. were studied on seed germination and seedling growth of three legume crops (Phaseolus vulgaris L., Pisum sativum L., and Vicia faba L.), three Labiatae species (Thymus vulgaris L., Melissa officinalis L., and Mentha spicata L.), and two species of Poaceae (Avena fatua L., Sorghum halepense L.). Seed germination of all L...

BACKGROUND The rhizomes of Cynodon dactylon are used for the treatment of heart failure in folk medicine. In the present study, we investigated the effects of hydroalcoholic extract of C. dactylon rhizomes on cardiac contractility in normal hearts and on cardiac functions in right-heart failure in rats. METHODS Right-heart failure was induced by intraperitoneal injection of monocrotaline (50 ...
