Terrestrial vegetation dynamics are closely influenced by both climate and by both climate and by land use and/or land cover change (LULCC) caused by human activities. Both can change over time in a monotonic way and it can be difficult to separate the effects of climate change from LULCC on vegetation. Here we attempt to attribute trends in the fractional green vegetation cover to climate vari...

To assess the variation in distribution, extent, and NPP of global natural vegetation in response to climate change in the period 1911-2000 and to provide a feasible method for climate change research in regions where historical data is difficult to obtain. In this research, variations in spatiotemporal distributions of global potential natural vegetation (PNV) from 1911 to 2000 were analyzed w...

Changes to animal movement in response to human-induced changes to the environment are of growing concern in conservation. Most research on this problem has focused on terrestrial endotherms, but changes to herpetofaunal movement are also of concern given their limited dispersal abilities and specialized thermophysiological requirements. Animals in the desert region of the southwestern United S...

Mountains over the world are considered as the indicators of climate change. The Himalayas is comprised of five ranges viz., Pir Panjal, Great Himalayas, Zanskar, Ladhak and Karakorum. Ladakh region lies in the northern most state of India, Jammu and Kashmir, in the Ladhak range. It has a unique cold-arid climate and lies immediately south of the Karakorum range. With scarce water resources, su...

Climate change is predicted to place up to one in six species at risk of extinction in coming decades, but extinction probability is likely to be influenced further by biotic interactions such as predation. We use structural equation modelling to integrate results from remote camera trapping and long-term (17-22 years) regional-scale (8000 km2) datasets on vegetation and small vertebrates (grea...

although the geographic and climatic conditions of the desert itself is not really growing, knowing about the iranian desert is important. what expands the deserts is the relationship of the desert areas with of the natural environment itself. degradation of water resources, soil and especially vegetation in the desert belt of iran provided conditions caused desertification and their spread on ...

The paper highlights the growing concern of the impact of climate change and variability including rainfall anomaly, rising temperature in mountain areas and occurrence of heat waves in relation to human mortality pattern in India. The paper investigates the historical perspective of rainfall and malaria relationship, and cited current studies to show how climate change and variability resulted...

1. Introduction In dry desert regions like the Southwest U.S., natural and human systems are particularly sensitive to variations in climate. The natural ecosystem of the Sonoran Desert is largely dependent on and adapted to monsoon precipitation, which is also needed to maintain water demand and agriculture from year to year. From a resource management perspective, the monsoon is relevant in t...

A compilation of 1884 modern pollen surface samples was analyzed to explore the relationships between spatial distributions of pollen percentage data vs. climate and vegetation in western North America. Modern pollen spectra capture many of the unique traits of regional vegetation patterns and reflect regional patterns of climate diversity. Large-scale vegetation differences were identifiable b...
