Poisonous native range plants
Plant poisoning is a common problem throughout North America, causing significant economic losses not only through death loss, but through the costs associated with reproductive loss, poor growth rates, herbicides, etc. Through good pasture management, recognizing toxic plants, and by understanding the effects of toxins on animals, plant poisoning can be largely avoided. Plants contain a variet...
متن کاملSolidago gigantea plants from nonnative ranges compensate more in response to damage than plants from the native range.
Resistance and tolerance are two ways that plants cope with herbivory. Tolerance, the ability of a plant to regrow or reproduce after being consumed, has been studied less than resistance, but this trait varies widely among species and has considerable potential to affect the ecology of plant species. One particular aspect of tolerance, compensatory responses, can evolve rapidly in plant specie...
متن کاملInvasion success of a scarab beetle within its native range: host range expansion versus host-shift
Only recently has it been formally acknowledged that native species can occasionally reach the status of 'pest' or 'invasive species' within their own native range. The study of such species has potential to help unravel fundamental aspects of biological invasions. A good model for such a study is the New Zealand native scarab beetle, Costelytra zealandica (White), which even in the presence of...
متن کاملBiocontrol strategy, Compost, Soil-borne pathogens management
The effect of different compost-soil ratios on the incidence of Pythium aphanidermatum causing tomato damping off was tested in a greenhouse experiment. The inoculum density of 5% was determined to be suitable for inoculation in compost experiments based on investigations of disease incidence with 5, 10 and 20% inoculum densities. To evaluate the effect of compost on incidence of tomato damping...
متن کاملIsolation of high-quality RNA from a wide range of woody plants
Isolation of high-quality RNA is one of the most crucial methods in molecular biology. RNA extraction from woody plants has been problematic due to the presence of rigid and woody tissues, large amounts of polysaccharides, polyphenols and other secondary metabolites. Here we present a suitable protocol for RNA isolation from a wide range of woody plants that includes eight gymnosperms and four ...
