Document Summary
Lecture 4: microclimate, principle of allocation, temperature regulation, extreme temperatures. If you have a larger shrug, there will be more ability to pass shade. Aquatic microclimate ( fig 5. 6: air temperature fluctuates more than terrestrial. Water has a high capacity to capture heat. Principle of allocation: the amount of energy each organism has it limited (cannot consume candy bars, there is a limit), when energy is allocated to one function, it is taken away from another function. If you move energy for reproduction, you have less energy for growth (it is finite: the cost to grow is the benefit of reproduction. Range of tolerance & performance (5. 13: moss from boreal forest and a desert shrub are shown, plants from a cold place are better at photosynthesizing at cold temperatures. Balancing heat lost and heat gain: hs=hm +/- hcd+/- hcv+/-hr-he. Hcd: heat lost or gained from touching another substrate (two solids, physically touch)
