habitat destruction invasive species population pollution overharvesting

cools as it rises because fewer molecules

warms as it rises because exothermic reaction with UVb and oxygen

cools as it rises because not enough oxygen

warms as it rises because of xrays and gamma rays 4deg/1000m lapse rate

troposphere stratosphere mesosphere thermosphere

Hadley Ferrel - westerlies Polar - easterlies

6 degrees/1000m 10deg/1000m

conserve water reduce heat reduce water loss

small, dense pubescence - insulation succulent (heat capacity) reflective - parabolic to flower

lotic and lentic

unidirectional continuous physical change river continuum concept spatiotemporal heterogeneity species response

autochthonous allochthonous

slope volume oxygen content temperature energy input

mostly autochthonous from surrounding trees, consumed by shredders Oxygen high, temp low, PS/R <1

five factors never the same at any two points. energy inputs lead to this. no single river bioms

relative abundance changes, no single river biome

light absorption spatiotemporal heterogeneity species response

reds absorbed at top of ocean, then blue red and blue absorbed in lake, green and yellow left

euphotic: littoral and limnetic profundal benthic

zones with light

shoreline trophic levels, periphyton eaten by grazers -> fish -> piscivore

pelagic - not near shore 4 trophic levels (phyoplankton, zooplankton, fish, pescivore)

where respiration = photosynthesis
