Livestock exerts direct and indirect effects on plant communities, changing colonization and extinction rates of species and the surrounding environmental conditions. There is scarce knowledge on how and to what extent these effects control the floristic and functional composition of plant communities in grasslands. We performed an experiment that included several treatments simulating tramplin...
This study aimed to evaluate the impacts of different forage cutting intensities, obtained by grazing simulation, on floristic diversity and productivity a pasture cultivated with spreading liverseed grass. The experiment was set up in randomized block design, four replications treatments arranged 5 × 2 factorial scheme, five levels intensity simulated (0, 25, 50, 75, 95% canopy) associated two...
Aim Understanding the historical and contemporaneous drivers of invasion success in island systems can decisively contribute to identifying sources pathways that are more likely give rise new invaders. Based on a floristic-driven approach, we aimed at determining origins invasive alien flora Canary Islands shedding light mechanisms shaping their distribution within archipelago. Location Islands...
UNLABELLED Candidates with fulminant hepatic failure (Status-1A) receive the highest priority for liver transplantation (LT) in the United States. However, no studies have compared wait-list mortality risk among end-stage liver disease (ESLD) candidates with high Model for End-Stage Liver Disease (MELD) scores to those listed as Status-1A. We aimed to determine if there are MELD scores for ESLD...
BACKGROUND Clinical diagnosis of acute appendicitis is most difficult in fertile-age women. In this patient group up to 50% of open appendectomies are negative for appendicitis. We conducted a randomized study to compare laparoscopic and open appendectomy in young female patients with suspected acute appendicitis. METHODS Fifty female patients between the ages of 16 and 40 years presenting wi...
OBJECTIVE Medication errors can be caused by lack of agreement between what physicians believe patients are taking and what patients actually take. There has been little systematic research to find the best way to reconcile medication lists in primary care. The objective of this study was to assess the impact of 2 interventions on agreement between electronic medical record medication lists and...
this research investigates the vegetation of 4600 ha of polour semi-steppe rangelands in relation to edaphic and physiographical parameters in mazandaran province. for this purpose, 23 land units were selected from overlaying slope, aspect and elevation maps using geographic information system (gis). within each unit, 3 parallel transects with 100 m length, each containing 10 quadrates (accordi...
Currently, a Eucalyptus globule is common smallholder plantation species in the Wogera district. The significantly expanding on marginal and fertile farmlands. objective to analyze effects of globules woodlots their directions selected soil physicochemical properties yield wheat crop. Three with similar site conditions were for this particular study. Soil samples taken at depth 20 cm RCBD desig...
The contribution of litterfall (dead leaves, twigs, etc., fallen to the ground) and forest floor (organic residues such as in various stages decomposition, on top mineral soil) is fundamental both ecosystem sustainability soil greenhouse gases (GHG) exchange system with atmosphere. A focus forested wetlands particularly important, these systems account for a disproportionate amount global carbo...
