Leaf characteristics of two representative deciduous-tree species in Korean peninsula were compared to assess directional ridge effect on leaf traits of both species. Leaf mass per unit area (LMA) of Rhododendron schilippenbachii in south-facing ridge slope was significantly higher than that in north-facing ridge slope, while Quercus mongolica did not change LMA. Leaf mass of Q. mongolica was i...

Topography is an important factor in determining vegetation patterns in grasslands. We collected frequency of occurrence data from transects on dune tops, south-facing slopes, north-facing slopes, and interdunal valleys in the eastern Sandhills of Nebraska to determine the effect of topographical position on plant species composition. We used canonical discriminant analysis to separate the four...

Introduction: Mars Orbiter Laser Altimeter (MOLA) onboard Mars Global Surveyor (MGS) spacecraft produced a large homogeneous data set of precise elevation measurements along MGS tracks [1]. We have used this data set to map and study statistical characteristics of kilometerand subkilometer-scale topography [e.g., 2, 3]. In the present work we use MOLA data set to map and study slope asymmetry o...

Bryophytes are poikilohydric organisms that can be used as model plants to study desiccation tolerance mechanisms. The main objective of this was examine the activities antioxidant enzymes ascorbate peroxidase (APX), catalase (CAT) and guaiacol (POD) in rehydrated desiccated states Syntrichia ruralis (Hedw.) Web. & Mohr. from two slopes, one North-east (NE) South-west (SW) facing collected ...

The widespread hillslope- and gully-erosion in Liaoning Province of Northeast China, pose serious challenges to the local agricultural production. Hillslope- have typically been studied separately; however, there has little investigation on relationship these two types erosion. In this study, coupling from perspectives erosion intensity land use, as well slope gradient, aspect, shape, was analy...
