Experience Many years of field experience with public land management agencies in western states (Alaska, Oregon, Washington, Idaho, Nevada, Arizona, Colorado, California). I have expertise in wildlife biology, zoology, ecology, fisheries, plant ecology,
forestry, watershed management, and other natural sciences. Target areas especially in great Basin, N. Rocky Mtns., coastal forests, intermountain region, southwest deserts (but not limited to these locations).
Education/Credentials BS Zoology University of Nevada; MS Arid Lands Ecology, Univ. of Nevada.
Question what are 2 kinds of disturbances that change ecosystems?
Answer Ecosystems, by the very nature of their internal dynamics, are changing constantly...at inconsistant rates of change. Therefore, I assume that you are talking about catastrophic or cataclysmic occurrences that make rapid changes in a system. So, disease to a particular plant or animal that is and indicator for that system (like widespread moth outbreaks in conifers that kill trees and make the whole system at risk for fire); climatic events like global warming, el nino, even large storms, volcanic eruptions, artificial changes like burgeoning population effects on rural areas and city edges (city development can change whole temperature and rainfall patterns over a large area), or channeling and damming of rivers, etc. etc. If you think about it...evidence of these changes (on various scales of effects) are all around us.
You can pick and choose if you only need two. Good luck.
