Chromosomal plasticity: mitigating the impacts of herbivory.

Environmental Education for Mitigating and Assessing Environmental Impacts of Petrochemical Products (Vinyl Chloride) with Analytic Hierarchy Process (AHP) Method

today, with rapid advancement of industry and technology, many concerns about the adverse consequences threaten human life. The objective of this research is to investigate environmental education as an implement to reduce and evaluate the environmental consequences of petrochemical products based on the hierarchical analysis. The methodology was a survey of a statistical group involving 30 man...

Phenotypic plasticity to light competition and herbivory in Chenopodium album (Chenopodiaceae).

Competition and herbivory are ubiquitous environmental challenges that affect most plants. We examined the influence of phenotypic responses to either competition or herbivory on the subsequent response of the plants to the other factor. The stem-elongation response of Chenopodium album to light competition attenuated its resistance to caterpillar herbivory in terms of herbivore mortality, but ...

Effects of Herbivory on Plant and Soil Characteristics; Allometric Relationships Change among Different Grazing Sites

Deer herbivory alters forest response to canopy decline caused by an exotic insect pest.

Hemlock woolly adelgid (HWA; Adelges tsugae) infestations have resulted in the continuing decline of eastern hemlock (Tsuga canadensis) throughout much of the eastern United States. While the initial impacts of HWA infestations have been documented, our understanding of forest response to this disturbance remains incomplete. HWA infestation is not occurring in isolation but within a complex eco...

Elevated Highways in Residential Layouts: The Imposed Negative Impacts (Case Study: Sadr Elevated Highway)

Fast growing population, excessive expansion of cities, and dominance of automobile in urban life have troubled cities with complicated traffic problems. In many parts of the world, transport network development has always been considered as a solution for this problem. Apparently, one-dimensional ‘traffic solutions’ would never thoroughly bring best results as the city and its problems are com...
