When using a 3D deterministic model to evaluate the landslide susceptibility of regional area, processing large amounts of spatial data and identifying the objective for applying the deterministic model would be arduous works. In this research, an enhanced hydrology tool is developed to automatically identify the objectives of research, which are called slope units, from terrain raster data. A ...

We investigated ontogenetic trends in body shape of 54 freshwater (48 lake, seven stream) and six anadromous populations of threespine stickleback (Gasterosteus aculeatus L.) from the Haida Gwaii archipelago off the west coast of Canada. Multivariate analysis of covariance on the partial warp scores generated from 12 homologous landmarks on 1,958 digital images of subadult and adult male stickl...

The present work aims to analyse jointly four contiguous watersheds in the eastern part of the Serra da Mantiqueira with respect to the distribution of fish fauna and physical structure. The watersheds of Piracuama river, Ribeirão Grande, Buenos and Guaratinguetá are located in Pindamonhangaba, Campos do Jordão and Guaratinguetá municipalities, in the state of São Paulo. Data were collected bet...

[1] It is demonstrated that a near-linear subsurface runoff response from a short and relatively steep slope segment and a nonlinear response at the watershed scale may primarily arise from geometry rather than from an assumed linear nature of the subsurface runoff response from the hillslope, as Harman et al. [2009] employed for the Panola Mountain Research (PMR) catchment in Georgia. The auth...

a r t i c l e i n f o Keywords: Payment-for-ecosystem-service Family structure Sustainable livelihood Wage-labor supply This research introduces family composition into the sustainable livelihoods framework for policy analysis. We apply this approach to a case study on the Grain for Green Program in western China. Using recent survey data from Zhouzhi County, we show that the impact of the poli...
