Human activities affect wildlife in several ways, ungulates tend to avoid areas of high human use and alter their behavior activity. We used remote camera traps quantify the relative abundance activity wild low within Nagarjunasagar Srisailam Tiger Reserve (NSTR). Major NSTR included collection forest produce fuel wood, livestock grazing. Poaching for bush-meat hunting dogs was also prevalent, ...

Vegetation stripes ("tiger bush") are a characteristic feature of semi-arid environments. The stripes typically lie along the contours of gentle slopes, and some authors report a gradual uphill migration. A previous mathematical model (Klausmeier, Science, 284:1826, 1999) has shown that this phenomenon can be explained relatively simply by the downhill flow of rainwater coupled with the diffusi...

A rhombic planform nonlinear cross-diffusive instability analysis is applied to a particular interaction-diffusion plant-ground water model system in an arid flat environment. This model contains a plant root suction effect as a cross-diffusion term in the ground water equation. In addition a threshold-dependent paradigm that differs from the usually employed implicit zero-threshold methodology...

A new cryptic species of bush frog Raorchestes honnametti sp. nov. is described from the south-eastern part of the Western Ghats, India. This newly described species belongs to the Charius clade and is morphologically similar to other clade members--R. charius and R. griet. Therefore, an integrative taxonomic approach based on molecular and bioacoustic analysis along with morphology was used to...

In semi-arid regions, infiltration of rain water into the soil is significantly higher in vegetated areas than for bare ground. However, quantitative data on the dependence of infiltration capacity on plant biomass is very limited. In this paper, we use a simple reaction-diffusion-advection model to investigate the effects of varying the strength of this dependence. We begin by studying the for...

Lepš, J., Goldberg, D.E., Herben, T. & Palmer, M. — Mechanistic explanations of community structure: Introduction Stampfli, A. & Zeiter, M. — Plant species decline due to abandonment of meadows cannot easily be reversed by mowing. A case study from the southern Alps Brewer, S.W. & Rejmánek, M. — Small rodents as significant dispersers of tree seeds in a Neotropical forest Kotorová, I. & Lepš, J...

     Periodic vegetation patterns (PVPs) are striking features of many global drylands. Although they have attracted wide research study, resulting in many hypotheses, their origin and controlling factors remain unresolved. Theoretical works dominate a large literature seeking to account for the occurrence and properties of PVPs, especially banded vegetation patterns (‘tiger bush’). In light of...

The learning difficulties of Down Syndrome students are often related to limitation of their short term memory. They have constraints in separating the information received by the brain. This leads to difficulties in reading process. Therefore, they fail to focus when learning. Scaffolding is a systematic assistance used to ease the burden of the short term memory of the Down Syndrome students....
