Modern food habits in humans have increased the frequency of diseases especially colon cancer. The present findings suggest potential efficacy two endemic Strobilanthes species Southern Western Ghats. shoot extract plants showed high radical scavenging activity hydroxyl assay at an half maximal inhibitory concentration 375.24±2.03 and μg/ml against gallic acid for anamallaica virendrakumarana r...

To determine the optimal anti-herbivore defence allocation of a plant, a modelling approach is inevitable. However, models have too often been detached from field experiments and aloof of ecological knowledge. Here I present the case for combining the two approaches. Two preconditions for a simple model have to be fulfilled: 1. the investigated species should show no inducible resistance, a phe...

for assessment and comparison of measuring density methods of festuca ovina, bromus tomentellus and prangos ferulacea, three plants communities are selected. in all of plant community, reference area was defined and samples 7000 (70*100) square meter was selected. whole the area, sampling was accumplished as systematic-random. in each area, 5 transect 100 meter are established. then in areas 70...

a hydroponic experiment was conducted to investigate the effect of of magnesium (mg) deficiency on plant cell metabolism in pgs durum wheat cultivar. the experiment was conducted in 4 replications as a completely randomized design in 2010. result showed that magnesium deficiency increased reactive oxygen species (ros) production such as hydrogen peroxide (h2o2). furthermore, mg deficiency decli...

Shifts in species' phenology in response to climate change have wide-ranging consequences for ecological systems. However, significant variability in species' responses, together with limited data, frustrates efforts to forecast the consequences of ongoing phenological changes. Herein, we use a case study of three North American plant communities to explore the implications of variability acros...

We compared the effect of herbivory by two congeneric specialist weevils (Neochetina eichhorniae and Neochetina bruchi) on competition between their host Eichhornia crassipes and another floating aquatic plant (Pistia stratiotes) by experimentally manipulating plant densities, presence of either or both herbivore species, and nutrient levels. Measurements of E. crassipes yield per original plan...
