Identify: What do I see on the graph? Interpret: What does the info on the graph mean? CHAPTER 40A An Introduction to Ecology and the

Biosphere You Must Know

The role of abiotic factors in the

formation of biomes. Features of freshwater and marine biomes. Major terrestrial biomes and their characteristics.

Ecology: the scientific study of the interactions between organisms and the environment

The ecological study of species involves biotic and abiotic influences.

Biotic = living (organisms behaviors & interactions between organisms) Abiotic = nonliving (temp, water, salinity,

sunlight, soil) Heirarchy

Organisms Population: group of individuals of same

species living in a particular geographic area Community: group of populations of different species in an area Ecosystem: community of organisms +

physical factors Landscape: mosaic of connected ecosystems Biosphere: global ecosystem

Climate: long-term prevailing weather conditions in a particular area

Climate = temperature + precipitation + sunlight + wind Macroclimate vs. microclimate:

Macro: work at seasonal, regional or local

level Micro: small-scale environmental variation (eg. under a log) Climate change: some species may not

survive shifting ranges Global Climate Patterns: Sunlight intensity

Global Climate Patterns: Air Circulation & Precipitation Patterns Global Climate Patterns: Ocean Currents

Global Climate Patterns: Mountains affect rainfall Biomes: major types of ecosystems

that occupy very broad geographic regions Figure 34.7C

Climate, latitude, and elevation determine biomes Figure 34.12

Which biome do these graphs represent? Biogeography:

Biogeography geographic distribution of species Factors:

Dispersal movement away from area of origin Behavior habitat selection Biotic factors other species, food resources, competition, pollinators,

predators Abiotic factors temp, water, oxygen, salinity, sunlight, rocks & soil What factors may have influenced

the distribution of this species?
