Field and ground layer vegetation in a mature Norway spruce (Picea abies L.) forest of Myrtillus-type in Kuorevesi, southern Finland, was sampled on 31 plots of sizes 0.5, 1 and 2 m to find optimal balance among sampling effort, number of observed species, and accuracy of mean species-cover estimates. Rarefaction and bootstrapping were used in the data analysis. According to the results, the ad...

in order to investigate some silvicultural and soil physico-chemical characteristics of christ's thorn (ziziphus spina christi l. desf.) natural stands, ten natural stands of the tree species which have similar climate and aspects were selected and altitude from sea level (asl), the thickest sprout collar diameter (tscd) and total tree height (th) of the tree species were measured in 1000 ...

cover crops cultivation and application of plant growth rhizobacteria are the key factors to enhance agroecosystem health. a field experiment was conducted at the research farm of faculty of agriculture, ferdowsi university of mashhad, iran, during growing season of 2009-2010. a split plot arrangement based on a complete randomized block design with three replications was used. cultivation and ...

Assessment and monitoring of rangeland in different grazing managements seems necessary to manage rangelands. The plant functional groups can be used as appropriate responders for rangelands condition and management. Therefore, this study was performed and aimed to determine the most important traits that are influenced by rangeland variation and management. In order to this, three areas along ...

Abstract. Rangeland vegetation dynamics encompass all processes of changes in vegetation composition and structure over time. Investigating the rangeland ecosystem dynamics makes it possible to determine the effects of climatic and management conditions on qualitative and quantitative changes of the vegetation in a specific period of time. Accordingly, data collection and measurements for evalu...

the effect of soil and phanerogam characteristics on bryophytes composition, richness, abundance and functional groups were investigated in order to understand the factors responsible for bryophytes distribution patterns. three different sand dunes were selected: untouched, artificial sod-covered and planted by ammophila. along 10 transects perpendicular to the shore, a total of 142 permanent r...
