Understanding landscape conversion is vital for assessing the impacts of ecological and anthropogenic disturbances at regional and global scales. Since rangelands cover nearly half of the global land surface, and because a large part of rangelands is located in semi-arid ecosystems, they serve as critical land cover types for determining regional biodiversity, global biogeochemical cycles, and ...

Ecosystems in the Central Asian Plateau, which includes the Mongolian Plateau, are becoming increasingly sensitive to human interventions, leading to deterioration of already fragile ecosystems. The goal of this paper is to illustrate human dependence on an ecosystem by identifying patterns of resource consumption in this region and investigating the knowledge and perceptions of herders living ...

soil erosion is undoubtedly one of the most important problems in natural areas and has a devastating impact on grassland ecosystems. the present study was conducted to assess the ability of rangeland hydrology and erosion model for estimating sediment yield on rangeland’s hill slopes in dry regions at shahid noori paired watershed of kakhk. rhem is a mathematical, distribution and physical mod...

water resources suitability is one of the most important factors to sustainabilityutilization of natural potential by rangeland grazing suitability. to determine this factor inshort time, low cost and high accuracy are most challenges of experts and ranchers. usingsuitable technique for this subject can be sustainable utilization comprising from rangelandecosystems according to its degradation ...

CARMA is an advisory system for rangeland grasshopper infestations that demonstrates how AI technology can deliver expert advice to compensate for cutbacks in public services. CARMA uses two knowledge sources for the key task of predicting forage consumption by grasshoppers: cases obtained by asking a group of experts to solve representative hypothetical problems; and a numerical model of range...

Oak woodlands of Mediterranean ecosystems, a major component of biodiversity hotspots in Europe and North America, have undergone significant land-use change in recent centuries, including an increase in grazing intensity due to the widespread presence of cattle. Simultaneously, a decrease in oak regeneration has been observed, suggesting a link between cattle grazing intensity and limited oak ...

Many agent-based systems rely for their effectiveness on the intelligence of individual agents, and interaction among agents is required simply to coordinate these individually complex decisions. Specification and design methods for such systems focus on the internal architecture of individual agents. An alternative approach, “Synthetic Ecosystems,” uses relatively simple agents and draws heavi...

This article provides an annotated catalog of the Symphypleona and Neelipleona (Hexapoda: Collembola) Iran based on published literature specimens recently collected from three different ecosystems in North Khorasan province (Forest, Rangeland, Agricultural) years 2018 2019. Thirty-five species seven families 17 genera are listed. Among them, Megalothorax minimus Bourletiella sp. recorded for f...

Contemporary Australian rangeland management is characterised by concurrent processes of a continuing intensification of land management practices and simplification of landscape ecological processes. This dual characteristic is associated with increasing levels of potential conflict between land management practices that promote improved economic performance of rangeland enterprises at the app...
