introduction the complexity of natural ecosystem, as the rangelands, is caused to propose the different approaches toevaluatethe ecosystem on the basis of sustainable and systematic management. study on the interaction connectionsbetween plants and biotic and abiotic factors in the rangeland ecosystem can be achieved by relationsofmanagerial strategies in order to conduct the rangeland health. ...

braconidae (hymenoptera) communities at high altitudes in alfalfa fields of kerman province (iran) were analyzed. the communities were sampled by sweep netting in 2014 and 2015. samples were taken from three altitudinal transects: 1900–2300 m, 2400–2700 m and 2800–3100 m. a total of 1773 braconid specimens belonging to seven subfamilies were collected. alpha, beta and gamma diversities were ana...

Evaluation of range conditions and plant diversity circumstances can help to rangeland managers who establish their managerial approaches on the basis of ecological capabilities of rangeland ecosystems. Hence, surveying of rangelands was done in four sites of northern Alborz Mt. including western Alborz (Masooleh site), west to middle Alborz (Javaherdeh site), central area (Polour site), and ea...

BACKGROUND There is an increasing demand for rapid biodiversity assessment tools that have a broad taxonomic coverage. Here we evaluate a suite of environmental DNA (eDNA) markers coupled with next generation sequencing (NGS) that span the tree of life, comparing them with traditional biodiversity monitoring tools within ten 20×20 meter plots along a 700 meter elevational gradient. RESULTS Fr...

Introduction: In most BCI articles which aim to separate movement imaginations, µ and &beta frequency bands have been used. In this paper, the effect of presence and absence of &gamma band on performance improvement is discussed since movement imaginations affect &gamma frequency band as well. Methods: In this study we used data set 2a from BCI Competition IV. In this data set, 9 healthy sub...
