Document Summary
Physiological ecology: the study of short and long term behavioral and physiological adjustments organisms make to survive and reproduce successfully in their changing environments. Can explain why subordinate males help dominant males in the absence of reproductive benefits for themselves: alan krakauer 2005 male wild turkeys. Coalitions of 2-4 birds that court and defend females; subordinate males are often brothers or half-brothers. R=0. 42 benefits=6. 1 extra offspring for dominants costs=0. 9 offspring loss to subordinates rb>c. Evolutionary advantageous for females to stay in hive and take care of sisters (other offspring of the queen: one reproductive female: eusociality. Common in habitats hard to escape (burrows, hives) Dominant individual can prevent others from reproducing. Naked mole rats: eusocial vertebrate (need to huddle for warmth, need the colony, need to cooperate in order to survive in the colony) Occurs when food is abundant enough to support the high concentrations of individuals. Drones cross fertilize other hives, what about the pesticide crisis/climate.
