Host Specificity of Cuscuta reflexa Roxb. in the Manas Biosphere Reserve, Indo-Burma Hotspot
The dodder plant Cuscuta reflexa Roxb. is an angiospermic leafless parasitic plant belonging to the family Cuscutaceae is abundantly found colonizing certain plant species in the premises of Manas Biosphere Reserve (MBR) and nearby area. Ten (10) angiospermic host plants in total of the above parasite were recognized. Based on the field inspection most of the numbers of patches were recorded in...
متن کاملPhotosynthesis in variable environments
Preface Photosynthesis in variable environments Photosynthesis is one of the most important biochemical processes, underlying almost all life. It is also one of the most vulnerable to environmental stress. Irradiance changes over the diurnal cycle is broadly predictable but, superimposed on that cycle, changes in cloud cover can cause order-of-magnitude variations in irradiance from second to s...
متن کاملEvolutionary Fitness in Variable Environments
One essential ingredient of evolutionary theory is the concept of fitness as a measure for a species’ success in its living conditions. Here, we quantify the effect of environmental fluctuations onto fitness by analytical calculations on a general evolutionary model and by studying corresponding individualbased microscopic models. We demonstrate that not only larger growth rates and viabilities...
متن کاملCoevolution in temporally variable environments.
Many potentially mutualistic interactions are conditional, with selection that varies between mutualism and antagonism over space and time. We develop a genetic model of temporally variable coevolution that incorporates stochastic fluctuations between mutualism and antagonism. We use this model to determine conditions necessary for the coevolution of matching traits between a host and a conditi...
