The loess hilly-gully region is a focus region of the "Grain for Green" program in China. Drought is the main problem in the study region. Precipitation and temperature are two indicators that directly characterize climatic drought. A thorough analysis of the precipitation, temperature and drought characteristics of the loess hilly-gully region can clarify the current water and heat conditions ...

We studied young riparian cottonwoods (Populus spp.) and associated woody plants along Soda Butte Creek and the Lamar River in northeastern Yellowstone National Park (YNP) to examine the potential influence of wolf/elk interactions upon plant growth. After a period of approximately 70 years without wolves in YNP, they were reintroduced in the winter of 1995–1996. When we compared woody plant he...

Rangelands cover approximately 85% of Kenya’s land mass and is a major resource for livestock farming with a considerable potential to mitigate climate change, yet these lands are stressed differently by various management. Our study aimed at determining the influence of grazing management systems (rotational, continuous and ungrazed) on soil organic carbon stocks in Yoani ranch located in the ...

Introduction: The discovery of gullies on Mars attracted significant attention because of the apparent role of liquid water in their formation and because of their very youthful nature [1,2]. They were initially interpreted to be the result of groundwater discharge [1-3], though further considerations regarding the current metastability of liquid water on the surface of Mars generated alternati...

Abstract Gully erosion affects the landscape and human life in many ways, including destruction of agricultural land infrastructures, altering hydraulic potential soils, as well water availability. Due to climate change, more areas are expected be affected by gully future, threatening especially low-income regions. In past decades, quantitative methods have been proposed simulate predict at dif...

Cold, dry, and nutrient-poor, the McMurdo Dry Valleys of Antarctica are among most extreme terrestrial environments on Earth. Numerous studies have described microbial communities low elevation soils streams below glaciers, while less is known about in higher above glaciers. We characterized life four landscape features (habitats) a mountain Taylor Valley. These habitats varied significantly so...
