Document Summary
Chapter 48 - biomes and global ecology (review) Warm summers and mild winters, abundant precipitation, growth of large conifers (redwoods, red cedar, douglas fir), undergrowth of grasses and ferns) Animals: diverse invertebrate species in soils, active microbial decomposers, high insect and vertebrate diversity. Latitude: below 50 degrees north in north america, northern japan, and parts of europe and continental asia. Moderate climate, dominance of harwoods, subjected to human disturbance for agriculture/urban development, 15-25 tree species (maples, oaks, birches), diverse understory flora, soils rich in nutrients from annual leaf fall, moderate temperatures and precipitation, cool winters. Animals: protists and invertebrate feed on microbes and fungi in soil, insects, birds, mammals (diverse), snakes, lizards, amphibians. Latitude: eastern north america, europe, and asia. Blue stem and buffalo grasses, disturbance by fire helps maintain grass populations, lack of precipitation, not many trees, active decomposers that help soils accumulate nutrients, most productive agricultural lands in the world.
