Vegetation structure and density affect the dynamics of snow accumulation and ablation. Vegetation also affects our ability to estimate snow-covered area accurately from satellite-based sensors. The objective of this case study is to demonstrate how the angular pattern of reflectance from vegetation over snow can provide information on forest cover density. Imagery from the Multi-angle Imaging ...

BACKGROUND In savannah-dominated Bénin, West Africa, and forest-dominated Gabon, Central Africa, plants are a major source of healthcare for women and children. Due to this high demand and the reliance on wild populations as sources for medicinal plants, overharvesting of African medicinal plants is a common concern. Few studies in Western Africa, however, have assessed variations in harvest pa...

[1] The enhancement of infiltration capacity in the presence of vegetation is well documented in arid ecosystems where it can significantly impact the water balance and vegetation spatial organization. To begin progress toward developing a theory of vegetation‐infiltration interactions across a wide spectrum of climate regimes, three key questions are addressed: (1) Does vegetation also enhance...

A wide-band waveguide transmission system and measuring technique have been developed to obtain continuous attenuation spectra of microwaves by vegetation in the frequency range 0.8–10.0 GHz. Laboratory experiments have been performed in order to examine the spectral dependence of the attenuation by different trees and tree fragments. Some results are presented showing the distinct difference o...

At the Northwest coast of Mexico the severely limited freshwater supply, and the geographic isolation determines the scarcity of productive activities. Specially at Baja California Sur. Aquaculture is a major productive alternative for the economic development of this State. Despite the aridity, the natural vegetation of Baja California Sur is diverse and structurally complex with a high percen...

Soil disturbance is recognized as an important driver of biodiversity in dry grasslands, and can therefore be implemented as a restoration measure. However, because community re-assembly following disturbance includes stochastic processes, a focus only on species richness or establishment success of particular species will not inform on how plant communities respond ecologically to disturbance....

Data on the effect of vegetation and land use type on soil organic carbon (SOC) distribution in particle-size and density fractions in the subtropical forest region in China will improve our understanding of the C sequestration potential of those different vegetation-land use types. We quantified SOC in particle size (coarse, medium and fine) and density fractions (light and heavy) under four t...

the objective of this research was to study the relationships between edaphic and topographic factors with distribution of plant species. for this purpose, current study was conducted in eshtehard rangelands of tehran province. the sampling method was randomized–systematic and in each sampling unit, three parallel transects with 750 m length containing 45 quadrates (according to vegetation vari...
