Understory plant communities play critical ecological roles in forest ecosystems. Both above- and below-ground ecosystem properties and processes influence these communities but relatively little is known about such effects at fine (i.e., one to several meters within-stand) scales, particularly for forests in which the canopy is dominated by a single species. An improved understanding of these ...

Abstract Nowadays, the importance of using macrophytes in accumulation heavy metals has gained great concerns. So, this study aimed at extracting land use/cover types three indices and surface temperatures habitats inside 100 m buffers from recent satellite images around highly economic namely; Phragmites australis, Typha domingensis Potamogeton pectinatus species. In addition to temperature (L...

The effects of invasive plants on the species diversity of plant communities are controversial, showing either a positive or negative linear relationship. Based on community data collected from forty 5 m×5 m plots invaded by Sphagneticola trilobata in eight cities across Hainan Island, China, we found S. trilobata decreased plant community diversity once its cover was beyond 10%. We demonstrate...

Questions: How do fire frequency, tree canopy cover, and their interactions influence cover of grasses, forbs and understorey woody plants in oak savannas and woodlands? Location: Minnesota, USA. Methods: We measured plant functional group cover and tree canopy cover on permanent plots within a long-term prescribed fire frequency experiment and used hierarchical linear modeling to assess plant ...

palatability includes plants physical and chemical property that encourages an animal selecta plant for grazing. this study is an attempt for intruducing an indicator for determining thepalatability of rangeland plants. to do this, the relationship between palatability and foragequality of rangeland plants in karsanak rangelands of the chaharmahal-va-bakhtiari provincewas studied. first, plant ...

Host-plant preferences were assessed by Þeldmeasurement of grasshopper abundance in relation to measurements of ßoral community and by laboratory host-plant preferences. Correlations between grasshoppers and plants (biomass and percentage cover) were based on data gathered at 29 study sites in Þve distinct Florida habitats (including disturbed, freshwater marsh, high pine, oak hammock, and swam...

Global Navigation Satellite System (GNSS) signals can be exploited to remotely sense atmosphere and land and ocean surface to retrieve a range of geophysical parameters. This paper proposes two new methods, termed as power-summation of differential Delay-Doppler Maps (PS-D) and pixel-number of differential Delay-Doppler Maps (PN-D), to distinguish between sea ice and sea water using differentia...

The seasonal snow cover of the Tibetan Plateau exerts a profound environmental influence both regionally and globally. Daily observations of snow depth at 37 meteorological stations in Tibet and MODIS eight-day snow products (MOD10A2) during the period 2001–2015 are analyzed with respect to the frequency and spatial distribution of snow cover for each season and for various altitude ranges. The...
