Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may occur but have never been addressed simultaneously. Using a standardized survey at 98 sites across six continents, we show that soil, are critical to explain delivery fundamental drylands Increasing pressure reduced service in warmer species-poor drylands, whereas positive...
Abstract We used three state-of-the-art machine learning techniques (boosted regression tree, random forest, and support vector machine) to produce a multi-hazard (MHR) map illustrating areas susceptible flooding, gully erosion, forest fires, earthquakes in Kohgiluyeh Boyer-Ahmad Province, Iran. The earthquake hazard was derived from probabilistic seismic analysis. mean decrease Gini (MDG) method implemented determine the relative importance of effective factors on spatial occurrence each...
Long-term research in grassland biodiversity experiments has provided empirical evidence that ecological and evolutionary processes are intertwined determining both biodiversity–ecosystem functioning (BEF) biodiversity–stability relationships. Focusing on plant diversity, we hypothesize multifunctional stability is highest high-diversity communities relationships increase over time due to a variety of forms complementarity including the interaction with other biota above below ground. We...
Understanding the responses of vegetation characteristics and soil properties to grazing in different precipitation regimes is useful for management rangelands, especially arid regions. In northeastern Iran, we studied livestock three regions with climates: arid, semiarid, subhumid. each region, selected 6-7 pairwise sampling areas high versus low intensity six traits present species were recorded on 1 m2 plots-five grazed five ungrazed area. The overall fertility was compared using...
Plant diversity measurement and monitoring are required for reversing biodiversity loss ensuring sustainable management. Traditional methods have been using in situ measurements to build multivariate models connecting environmental factors species diversity. Developments remotely sensed datasets, processing techniques, machine learning provide new opportunities assessing relevant parameters estimating In this study, geodiversity variables containing the topographic soil multi-seasonal...
Abstract Questions (a) Do patterns of species diversity and composition differ between plots exposed to high vs. low grazing intensity? (b) these differences vary among three regions with different climates, representing a gradient from arid sub‐humid conditions? Location Northeastern Iran. Methods We compared intensively grazed by sheep goat (HG) intensity (LG), across climatic regions: arid, semi‐arid sub‐humid. Species (expressed as Shannon H ) was using linear mixed‐effect models....
Abstract The interspecific plant interactions along grazing and aridity stress gradients represent a major research issue in ecology. However, the combined effects of these two factors on plant–plant have been poorly studied northeast Iran. To fill this knowledge gap, 144 plots were established 12 study sites with different intensities (high vs. low) climatic characteristics (arid semiarid) northeastern A dominant shrub, Artemisia kopetdaghensis , was selected as model species. Further, we...
Aridity and intensive grazing have been confirmed to affect the facilitative effects of dryland shrubs. However, their combined on plant-plant interactions rarely tested. To test how these two factors relations between plants, we analyzed 144 plots (under shrub canopy vs. open areas) at 12 sampling areas established in conditions regimes (high low intensity) different climatic regions (arid semi-arid) northeastern Iran. A dominant shrub, Artemisia kopetdaghensis, was selected as model...
