4. During class we discussed the following diagrams (A and B) and included a variety of terms/concepts. tail (labeling and explanation) to diagram B. that identifies the local and regional filters as imate invasion by lso, well as 3 different ways humans alter this pathway and result in the introduction and ult non-native species. You are to include specific examples of invasive species for these descriptions. A you are to include an explanation of what the various filters might be (you can include labels on the diagram and if necessary, write more of your answer on the back of this page). Additionally, you are to incorporate in your explanation some of the terms used in diagram A. The goal for this question blend the concepts of the two diagrams together to more thoroughly explain INVASIBILITY. 25 is to pts

Explanation / Answer

Fig 1 explain variation in terms of processes that control the availability of resources. These include not only abiotic and physical factors that determine base resource levels, but also interactions between species or between organisms and their environment that increase resource availability (through disturbance) or decrease resource availability (through competitive processes), or create new resources (through facilitation).

Fig 2. show transportation of species A B C beyond historic biogeographical barrier to new ecosystem. Where equential filter reduce the number that sucessfully establish A B C . an introduction efforts filter reduced both the number of species and individuals within particular species that reach the physiological filter.
