Leaf area index (LAI), one of the most crucial vegetation biophysical variables, is required to evaluate structural characteristic plant communities. This study, therefore, aimed LAI ecoregions in Iran obtained using Sentinel-2B, Landsat 8 (OLI), MODIS, and AVHRR data June July 2020. A field survey was performed different throughout Ardabil Province during 2020 under satellite image dates. Laip...

Herbivory and fire are natural interacting forces contributing to the maintenance of rangeland ecosystems. Wildfires in the sagebrush dominated ecosystems of the Great Basin are becoming larger and more frequent, and may dramatically alter plant communities and habitat. This synthesis describes what is currently known about the cumulative impacts of historic livestock grazing patterns and short...

The objective of the current study was to determine seasonal changes in glucose, cholesterol, non-esterified fatty acids (NEFA), serum inorganic phosphorous (SIP), calcium, magnesium and iron concentrations in Nguni and crossbred cattle on the sweet and sour rangelands of the Eastern Cape Province of South Africa. Body weights, body condition scores (BCS) and serum concentrations of energy-rela...

The objective of this paper is to examine the sustainability of rangeland agriculture (i.e., managed grazing) on a world-wide basis, with a focus on North America. Sustainability is addressed on three fronts: 1) ecological, 2) economic, and 3) social acceptance. Based on previous and on-going research, we suggest that employment of science-based rangeland grazing management strategies and tacti...

We assessed vegetation cover density and distribution in Eastern Jordanian rangeland reserves (2411 km2) using a series of Landsat images (34 year’s period) ground survey (2020) to identify proper sites for reintroducing Arabian Oryx (Oryx leucoryx). The natural were Burqu Nature Reserve site-1, site-2 (Dmetheh), Al Dahek Reserve. Satellite sensor data from Landsat-8-OLI Landsat- 5-TM used deri...

This study aims to assess the effects of land-use changes on carbon storage capacity and some soil properties The Sultan Marshes, a wetland partially drained converted other land uses during middle last century. Undisturbed sampling was performed in different types (rangelands, shrubs, marsh, agriculture, dried lake area) area at depths 0–50 cm, organic (SOC), bulk density, stocks soils for eac...

We studied consequences of storm damage on buttonwood (Conocarpus erectus) shrubs and their herbivores in the Bahamian islands. Buttonwood is polymorphic, with green shrubs producing few leaf trichomes and silver shrubs covered in dense trichomes. We first characterize traits of green vs. silver shrubs relevant for herbivores, and then assay damage by two prominent insects. Next, on replicated ...

In arid and semi-arid ecosystems, shrubs may act as fertility islands but theireffect may vary depending on their morphology and ecological impacts. This research wasaimed to study effect of three shrubs Scariola orientalis, Astragalus heratensis, and Rosapersica on soil properties and on the microclimate conditions (temperature, luminance, andsoil moisture) of their understory in the steppe ra...

The complexity of natural resource management is increasingly recognized and requires adaptive governance at multiple levels. It is particularly significant to explore the impacts of government interventions on the management practices of local communities and on target social-ecological systems. The Inner Mongolian rangeland was traditionally managed by indigenous people using their own instit...
