APES biomes & Terrestrial/aquatic biodiversity

APES

Savanna

scatterd trees, warm temps, loss of habitat, threatens native animals

deserts (3 types: tropical,temp,cold)

annual precipitation is low, scattered unevenly throughout the year, slow plant growth, low species diversity, slow nutrient recycling

Grasslands (3 types:savanna

in areas to moist for deserts but too dry for forests

tropical savanna

warm temps year around, grazing and browsing animals

temperate (grassland)

cold winters, hot, dry summers, tallgrass prairies, short-grass prairies, often converted farmland

artic tundra

plants close to ground to conserve heat, growth in short summer, animals have thick far permafrost

alpine tundra

above tree line in mountains

chaparral

dry temp biome, coastal regions that border deserts, thin soil

tropical forest

high moisture air, rapid recycling of scarce soil nutrients (poor)

temperate forest

cooler temp, abundant moisture, slow rate of decomposition

coastal coniferous forest

scattered coastal regions,rainfall and moisture form fog

cold coniferous

south of artic tundra, cold winters and short summers

coral reefs

world’s oldest, most diverse, productive ecosystem

in clear, warm water, tropical areas

calcium carbonate shells=coral reefs

tiny animals & single celled algae

coastal zone

warm shallow water, 10% of world’s ocean. contains 90% of all marine species

estauries

river meets sea

coastal wetlands

coastal land covered with water all or part of the year, include coastal marshes and mangrove forests

seagrass beds

occur in shallow coastal water up to 60 species of grasses and plants, variety of marine species

mangrove

hiding spots for baby fish, roots taken out of water

intertidal zone

area of shore between high and low tides

sandy shores

most organisms burrow, dig or tunnel in sand

oligotrophic lakes

low levels of nutrients and low npp, clear waters

eutrophic lakes

high levels of nutrients, high upp, shallow murky water

nitrates

NO3

Nitrite

NO2
