Compositional (2 POINTS):  e.g. landscape  types; communities;  ecosystems; species; populations; genes (1 POINT) 2. Structural (2 POINTS): e.g. landscape  patterns; habitat structure;  population  structure; genetic structure; habitat locations; habitat  connections (1 POINT) (“habitat types” without  mentioning  connections  or structure  = 0.5 POINTS) 3. Functional (2 POINTS): e.g. genetic processes; demographic processes  such as dispersal, birth and  death  rates and  life histories; interspecific  interactions; ecosystem  processes such as pollination  and  dispersal;  landscape  processes; disturbances; land  use trends  (1 POINT) 2. As discussed  in class and  in your textbook, conservation  biology has several  unique  characteristics that distinguish  it from other more "basic" sciences. List   THREE  of these characteristics.  (6 POINTS) (2 POINTS) 1. Value-laden  science      as opposed  to other more “basic” sciences; conservation   biology is oriented  by a mission  to preserve biodiversity rather than  by a basic  question  or hypothesis 2. Crisis discipline     ; triage  mentality 3. Inexact science     : Decisions have to be made  in the face of uncertainty . 4. Science with  an evolutionary  timescale . 5. Science of eternal vigilance . (1 POINT) “Multi-disciplinary  science” and  uses the basic sciences

EEB 116 Winter 2007 Midterm  1 Name_________________________________ 3.  How  is the definition  of species used  in the Endangered  Species Act different  from that commonly  used  by biologists?  (4 POINTS) 4 POINTS – full definition  of both; or explanation  that ESA definition  is more broad   and  includes  subspecies/“distinct”  populations
