Vegetation size in patients with infective endocarditis.
AIMS Infective endocarditis is a serious disease with diverse clinical manifestations. The aim of this work was to analyse vegetations' size in relation to the clinical presentation, course of the disease, and the type of the microorganism. METHODS AND RESULTS A total of 146 patients with definite diagnosis of infective endocarditis were identified at Assaf Harofeh Medical Center during the y...
متن کاملDetermining the sample size required to compare vegetation and soil characteristics in two independent groups using effect size
Extended Abstract Background and objectives: One of the important steps in assessing rangeland vegetation is determining the sample size. Adequacy of sample size and its determination is always one of the main concerns of rangeland vegetation analyzer. There are two general methods for determining the sample size in rangeland science: graphic and statistical methods. In this study, the sample...
متن کاملVegetation controls on the maximum size of coastal dunes.
Coastal dunes, in particular foredunes, support a resilient ecosystem and reduce coastal vulnerability to storms. In contrast to dry desert dunes, coastal dunes arise from interactions between biological and physical processes. Ecologists have traditionally addressed coastal ecosystems by assuming that they adapt to preexisting dune topography, whereas geomorphologists have studied the properti...
متن کاملIs the patch size distribution of vegetation a suitable indicator of desertification processes? Comment.
The monitoring of desertification processes, and particularly the development of "early-warning" systems, is an increasingly important development in the management of drylands. It has been shown that the patch size distribution of dryland vegetation can be described using power laws and that deviations from such patterns may be used as an early-warning signal for the onset of desertification. ...
متن کاملSample Size Requirements for In Situ Vegetation and Substrate Classifications in Shallow, Natural Nebraska Lakes
—We assessed the precision of visual estimates of vegetation and substrate along transects in 15 shallow, natural Nebraska lakes. Vegetation type (submergent or emergent), vegetation density (sparse, moderate, or dense), and substrate composition (percentage sand, muck, and clay; to the nearest 10%) were estimated at 25–70 sampling sites per lake by two independent observers. Observer agreement...
