Predicting the impact of land-use change on water and salt generation from upland areas at a catchment scale is a difficult task. Across large catchments there are often limited field measurements, and so predictions are forced to rely on modelling. However, at this scale input data for models is usually restricted to information surfaces such as rainfall, geology, and surface topography, and h...

Location The eight study sites are located in southern New England in the states of Massachusetts and Connecticut. The sites span a climatic and vegetational gradient from the lowland areas of eastern Massachusetts and Connecticut to the uplands of north-central and western Massachusetts. Tsuga canadensis and Fagus grandifolia are abundant in the upland area, while Quercus, Carya and Pinus spec...

Although the discovery of aquaporins in plants has resulted in a paradigm shift in the understanding of plant water relations, the relationship between aquaporins and drought resistance still remains elusive. From an agronomic viewpoint, upland rice is traditionally considered as showing drought avoidance. In the investigation of different morphological and physiological responses of upland ric...

Abstract Rabbits are a potential livestock commodity to supply quality meat with higher protein and lower fat cholesterol content than other meat. Helminthiasis is parasitic worm infection that has imposed economic loss involving some risk factors. This study aimed investigate the helminthiasis cases in both upland lowland areas, as well their factors on of rabbit farming. A total 192 samples w...

The stress-induced epimutations could be inherited over generations and play important roles in plant adaption to stressful environments. Upland rice has been domesticated in water-limited environments for thousands of years and accumulated drought-induced epimutations of DNA methylation, making it epigenetically differentiated from lowland rice. To study the epigenetic differentiation between ...

Manganese (Mn) in surface waters is a micronutrient, but elevated concentrations are toxic to fish and impair drinking water quality. In Scotland, undesirable Mn concentrations (> 0.05 mg l(-1)) occur predominantly in upland freshwaters because the acidic pH and organic nature of catchment soils favour Mn mobilisation. The relationship between upland land-use in Scotland and Mn concentrations i...
