Semelparity

Semelparity

Individuals reproduce only once during lifetime. May offspring with little to no parental care

Iteroparity

Individuals reproduce repeatedly during their lifetime. few offspring are produced and provide high parental care

Aposematic Coloration

Bright colors serve as a warning

Cryptic coloration

Blending with the environment

Batesian Mimicry

Harmless species look like species that are harmfull

Mullerian Mimicry

Multiple species with the same defense have the same coloration

Boreal Forest

Coniferous & Taiga Forests; low temp and predictable rainfall. soil low in nitrogen

Arctic Tundra

Very low temp and rainfall, extreme sunlight conditions, permafrost soil

Temperate forest

Deciduous forest, annual temp fluctuation, predictable rainfall, soil rich in organic material

Chapparal

Scrub forest, intense temp swings, winter rainfall

Temperate Grasslands

Praries & Steppes, annual temp fluctuation, periodic rainfall, dense grass, fire is abiotic factor

Subtropical Deserts

Narrow range, intense temps, unpredictable rainfall, burrowing animals

Savannah

Grasslands with scattered trees, hot temps, minimal rainfall, fire is important abiotic factor

Tropical wet forest

Equatorial regions, plants have year round growth, rainfall variable, highest animal/plant biodiversity

Ordovician-silurian

Life in oceans; 85% of species extinct, caused unknown

Devonian

Affected marine species ony; 70-80% of species extinct; cause not understood

Permian

Largest extinction on earth; 96% marine, 70% terrestrial; extensive volcanic eruptions

Triassic-Jurassic

85% of species; unknown cause

Cretaceous

Dinosaurs extinct; caused by asterioid
