|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




seeks to understand course of the natural world and our interactions with it
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||

|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




in another
|||||| ||||||




- what factors determine the range and distribution of species in the environment
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




parts of a transplant experiment - correct answer ✔-realized range: occupied by species of
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




interest
-potential range ||||||




-control: treatment in which nothing is changed |||||| |||||| |||||| |||||| |||||| ||||||




steps/summary of transplant experiment - correct answer ✔1. take organism and move it |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




outside of realized range |||||| |||||| ||||||




2. have a control and treat it like the organisms being transplanted. if all controls die you
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




need to make move less stressful |||||| |||||| |||||| |||||| ||||||




what limits the distribution in transplant experiments? - correct answer ✔- biotic and
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




abiotic factors (environmental conditions) |||||| |||||| ||||||




-dispersal
-habitat selection ||||||




-time

, 3 primary reasons we dont find organism in potential range - correct answer ✔1. failure to
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




recognize (as suitable habitat) |||||| |||||| ||||||




2. dispersal barrier (cant get there)
|||||| |||||| |||||| |||||| ||||||




3. not enough time (to colonize area)
|||||| |||||| |||||| |||||| |||||| ||||||




ethical consideration about transplant experiments - correct answer ✔-worry that the
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




species moved will cause issues |||||| |||||| |||||| |||||| ||||||




-environmental limitations: temp and moisture are main focus |||||| |||||| |||||| |||||| |||||| |||||| ||||||




physiological ecology - correct answer ✔studies the biochemical,physical, and mechanical |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




adaptations and limitations of organisms to their physical environment |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||

|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




taxa
- has been extended to elevational clines
|||||| |||||| |||||| |||||| |||||| ||||||




why do we observe the patterns of rapoports rule - correct answer ✔1. climatic variability:
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




only species with broad range would live at high latitudes
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




2.glaciation: colonization of high latitudes by broad dispersers; not as wide spread as |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




S.hemisphere
3. lack of competition because of reduced density
