Climate is the most important factor of plants distribution in global and regional scale. Understanding the current distribution of vegetation cover and its interaction with climate regularity is important for predicting its future. In order to determine the effective climate factors in plant life-form in Polour rangelands in the Damavand summit (2400 to 4100 m above sea level), Iran, a study w...
This article examines the centrality of Brazil within the future of climate policy and politics. The state of the carbon sink of the Amazon rainforest has long been an iconic marker of the condition of the Earth. Brazil has been innovative in developing many noncarbon forms of energy generation and use and it has played a major role in international debates on global warming since the Rio Earth...

Introduction: This study is aimed at analyzing farmers’ perception and adaptation to climate change in the Dabus watershed. It is based on analysis of data collected from 734 randomly selected farm householdheads substantiated with Focus Group Discussions and field observations. Methods: The study employed descriptive methods to assess farmers’ perception of climate change, localindicators of c...
in recent years multiple roles of wetland ecosystem and their values for human have increasingly been known, but their environmental and human life importance are usually considered to be less than their actual value. wetlands are one of the most important critical areas in the world. due to unique biodiversity and having high volume production, wetlands have special place from controlling role...
BACKGROUND Explaining species range size pattern is a central issue in biogeography and macroecology. Although several hypotheses have been proposed, the causes and processes underlying range size patterns are still not clearly understood. In this study, we documented the latitudinal mean range size patterns of terrestrial mammals in China, and evaluated whether that pattern conformed to the pr...

Drought is a complex hazard, and it has an impact on agricultural, ecological, and socio-economic systems. The vegetation condition index (VCI), which is derived from remote-sensing data, has been widely used for drought monitoring. However, VCI based on the normalized difference vegetation index (NDVI) does not perform well in certain circumstances. In this study, we examined the utility of th...
Desertification in Qinghai-Xizang (Tibet) Plateau is part of Chinese desertification. In the past decades, due to the climate warming, the climate condition in Qinghai-Xizang (Tibet) Plateau has been relatively dry. This has resulted in permafrost degradation and other environmental problems. In addition, the vegetation and the soil layer were also destroyed by unreasonable economic activities....
