The topographical morphology of the loess landform on Loess Plateau exhibits remarkable textural features at different spatial scales. However, existing topographic texture analysis studies are usually dominated by statistical characteristics and missing structural characteristics. At same time, there is a lack regularity calculation methods for DEM digital terrain analysis. Taking as study are...

Gully rehabilitation is often applied as part of catchment management strategies aimed at reducing downstream sediment yields. However, the influences gully control measures on runoff and transport processes in agroforestry systems have been seldom studied. In this paper, a thorough analysis these was carried out valley-bottom located dehesa from SW Spain. The monitored before after implementat...

A population of northern bottlenose whales (Hyperoodon ampullatus) uses the Gully, a submarine canyon off coast Nova Scotia, Canada. Eleven years photo-identification records has permitted estimation size using mark-recapture techniques. The estimate was small (133 individuals, 95% CI = 111-166 from left side identifications; 127 106-160 right identifications). not closed, with combined mortali...

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...

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...
