This paper reports the results of the in situ application of diffusive gradients in thin-films (DGT) passive samplers for trace metals (Cd, Co, Cr, Cu, Ni, Pb and Zn) monitoring in transboundary Udy and Lopan rivers of the Seversky Donets watershed in the Kharkiv region,Ukraine, which has a long history of industrial development. The research discusses potential sources of DGT-measured labile m...

We built a model of regulation for non point source water pollution through non linear taxation/subsidisation of agricultural production. Farms are heterogeneous along two dimensions: their ability to transform inputs into final production, and the available area they possess. We propose a framework for describing the ability of farmers, the cost and the emission joint functions from a populati...

The foraging strategies of wading birds may be influenced by their degree of crypsis to aquatic prey. White plumage has been hypothesized to be adaptive for herons hunting in open water habitats. We tested this hypothesis with laboratory and field experiments with multiple prey species. We investigated the response of crayfish, Procambarus spp., and mosquitofish, Gambusia affinis, to whiteand d...

The Snowy Mountains Hydro-electric Authority has recently undertaken a program of analysing the routine maintenance completed on its main generation and hydraulic assets. Power industry deregulation and increasing competition have created the need to reduce costs while increasing productivity. Along with downsizing and organisational restructuring, considerable effort has been placed on improvi...

Total change in production and productivity are the two important dimensions of benefits of watershed development programmes along with the conservation of land and water resources. To segregate out the impact of various watershed-based interventions on crop productivity, a study was carried out in Bundelkhand region of Madhya Pradesh state of India. Data were collected from 240 farmers’ select...
