They then incorporate these measurements into a life table and do a simple sensitivity analysis on the life table. The life table is constructed in a separate spreadsheet (such as Excel\x26reg;), and a section of the lab guides students through this construction. The rates used in the underlying model are the actual rates used in the spotted owl court cases, so this lab will work well in combination with a case study of the spotted owl debate in the Pacific Northwest.\x3c/span\x3e\x3cbr/\x3e\n\x3cbr/\x3e\n\x3cstrong\x3eLevel\x3c/strong\x3e: Advanced\x3cbr/\x3e\n\x3cstrong\x3eKey Concepts\x3c/strong\x3e: Life tables; Population dynamics\x3cbr/\x3e\n\x3cstrong\x3eCourses\x3c/strong\x3e: Applied Ecology; Conservation Biology; Ecology; Population Biology\x3cbr/\x3e\n          \x3cbr/\x3e\x3ca href=\"/search_result_details/brief/45\" class=\"node_brief\"\x3eRead less\x3c/a\x3e        \x3cbr/\x3e\x3ca href=\"/cart/add/45\"\x3e + Add to course collection\x3c/a\x3e  \x3c/span\x3e \x3c!-- description --\x3e\n" }
