Document Summary
Case study: burger king animal feed sourced from deforested lands in brazil and. Has been buying animal feed produced in soy plantations carved out by the burning of tropical forests in brazil and bolivia. Jaguars, giant anteaters, and sloths have all been affected by the disappearance of forest land between 2011 and 2015. Evolutionary, morphological, and distributional responses to climate change: the evidence. Rapid evolution hypothesis: strong and immediate climatic-based selection on population traits-evolutionary change. Plasticity hypothesis: strong and immediate climatic-based adjustments in growth, phenology, and reproduction-ecological change. Migration hypothesis: strong and immediate climatic-based adjustments in increased temp by 3. 5c; eliminated rainfall: an event of biblical proportions. Plasticity or adaptation? population distribution-migration or (cid:495)ecological selection(cid:495) Hidden long-term effect: inbreeding depression (cid:523)the (cid:494)lag effect(cid:495)(cid:524) Buffering: no net change in population size or population structure. Buxten climate change study calcareous grassland long term manipulations: temp/water interactions, plots, replicates.
