History and geography shape the ecology and evolution of insect pests, we may collectively develop a better capacity to identify where and how ecological pest management approaches can be most. The classification of species as either `native' or `alien' is one of the organizing principles of conservation, but the validity of this dualism has increasingly been questioned, sparking debates which raise quintessentially geographical questions about place, space, nature and humanity-nature interactions.

Invasive species, often recognized as ecosystem engineers, can dramatically alter geomorphic processes and landforms our review shows that the biogeomorphic impacts of invasive species are common, but variable in magnitude or severity, ranging from simple acceleration or deceleration of preexisting geomorphic processes to landscape metamorphosis. The gods would withdraw their support for a weak or corrupt ruler.
An invasive species is an organism that is not indigenous, or native, to a particular area invasive species can cause great economic and environmental harm to the new area to be invasive, a species must adapt to the new area easily it must reproduce quickly it must harm property, the economy, or. There has been a dramatic growth in research on biological invasions over the past 20 years, but a mature understanding of the field has been hampered because invasion biologists concerned with different taxa and different environments have largely adopted different model frameworks for the invasion process, resulting in a confusing range of concepts, terms and definitions.
