To test the effects of vegetation, four scenarios of laboratory-scale tests having both submerged and emergent artificial vegetation were conducted in a flume including; (1) no artificial vegetation (NAV), (2) submerged artificial vegetation (SAV) (3) emergent artificial vegetation (EAV), and (4) mix artificial vegetation (MAV).
The vegetation transition at treeline provides an opportunity to test the effects of vegetation, topography, and external inputs on soils at three spatial scales.
Based on replicated presence sign surveys conducted in autumn (November December 2013) and winter (February March 2014) in a farmland landscape, we used occupancy-detection modelling to test the effects of vegetation, sampling effort, observer experience, and rainfall on detection probability.
Further trials will be required to test a wider range of vegetation, and to examine performance over the longer term.
To test for the impact of vegetation loss on natural selection during the drought, we experimentally removed vegetation on a separate study island in a naturally wet year.
It is tested if the analysis of vegetation change from remote sensing time series can help to identify and map the zone that has been affected by significant ash fallout.
A landscape scale assessment of the effect of changes in precipitation on vegetation in three watersheds, spanning four southern African nations is undertaken and tests of statistical significance of vegetation changes developed.
The cross-taxon congruence of species diversity (species richness and species composition) among vascular plants, bryophytes, lichens, fungi, oligochaetes, butterflies and birds was investigated with special attention to testing the potential role of vegetation as surrogate for the other studied taxa.
We further tested the potential of a variety of vegetation and non-vegetation indices to predict land surface temperature.
The application of fertilizers followed a soil test of available potassium at the onset of vegetation.
SAVI as a measure of vegetation restoration was computed to test the relationship with LST and AAP pixel-by-pixel.
