Rangelands cover 70% of the world's land surface, and provide critical ecosystem services primary production, soil carbon storage, nutrient cycling. These are governed by very fine-scale spatial patterning carbon, nutrients, plant species at centimeter-to-meter scales, a phenomenon known as “islands fertility”. Such dynamics challenging to detect with most satellite manned airborne platforms. R...

Across the globe, rising temperatures and altered precipitation patterns have caused persistent regional droughts, lengthened fire seasons, and increased the number of weather-driven extreme fire events. Because wildfires currently impact an increasing proportion of the total area burned, land managers need to better understand reburns – in which previously burned areas can modify the patterns ...

in arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. a study was done to analyze the effects of grazing on plant species diversity and plant functional types‘ (pfts) diversity of arid and semi-arid rangelands. we analyzed plant richness and diversity data from 75 sa...

Mountain pocket gophers (Thomomy's talpoides) and plains pocket gophers (Geomys bursarius) are a problem to rangelands in Colorado. A new chlorophacinone (50 ppm) pelleted bait was applied to active burrow systems by hand baiting. Efficacy on the Geomys plot was 100%, while 94.73% of the Thomomys were controlled with the product. Introduction Pocket gophers, of the family Geomyidae, are indigen...

Australian rangelands ecosystems cover 81% of the continent but are understudied and continental-scale research has been limited in part by a lack of precise data that are standardised between jurisdictions. We present a new dataset from AusPlots Rangelands that enables integrative rangelands analysis due to its geographic scope and standardised methodology. The method provides data on vegetati...

Catchment-scale land-use change is recognised as a major threat to aquatic biodiversity and ecosystem functioning globally. In the UK uplands rotational vegetation burning is practised widely to boost production of recreational game birds, and while some recent studies have suggested burning can alter river water quality there has been minimal attention paid to effects on aquatic biota. We stud...

based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. this research was carried out in a part ofhighland mountainous rangeland of mount alborz range in iran. diversity and richnesswere assessed as an ecosystem health indicator. the study area was locate...

Grazing can alter plant species interactions in natural rangelands, which turn might influence the productivity of ecosystem but we do not fully understand how spatial variability diversity-biomass relationships are modulated by grazing intensity. Here, hypothesized that co-occurrence rangelands is mainly driven niche segregation due to and heterogeneity local resources, grazing, therefore, mod...
