Lecture 17: physiological ecology of plants more. Plant physiological ecology: stresses on plants are especially challenging because plants can"t evade stress by moving, plants solve problems by growth & development, not behaviour carbon balance is central, tradeoffs on photosynthesis compromises involve three necessities. Light a: temperature, water, adaptations to an extreme habitat: deserts, adaptations to an extreme lifestyle: epiphytes, sclerophylly: resolving a multi-part paradox. Many problems for plants result from them being sessile this produces a number of tradeoffs and compromises (centering around water and light sources). Under the descending air of ferrel cells, so there"s not much water in the system. This is one of the mountain ranges that surrounds the city. Desert has characteristic plants, cacti, but also this grey- green filmy look to them. Can grow without incurring heat load and water loss through leaves. Microphylly the condition of having small leaves.
