Chapter 49 An introduction to ecology
Type of terrestrial biome (
Arctic tundra and Boreal forests or taiga both have low productivity and species diversity but arctic has low-lying vegetation and boreal is dominated by cold-tolerant conifers
Temperate forest has a pretty normal productivity and species diversity including deciduous and evergreen trees
Temperate grassland has a lower productivity than the forest but has high fertile soil which is dominated by the grasses
Deserts and dry shrublands have extreme temperatures with low moisture and low productivity and plants that survive have adapted to water loss
Tropical forest has high productivity and species diversity and the only terrestrial biome with structural diversity including evergreen broad-leaved plants
Climate change is increasing temperature and precipitation variability
Each terrestrial biome is distinctly different in temperature, moisture, and sunlight leaving species in each biome adaptative to that environment
Types of Aquatic biome
Each aquatic biome is distinctly deciphered by the key abiotic factors: Salinity (the portion of solute dissolved in the natural environment), water depth, water flow, and nutrient availability
Its usually a low concentration of solute in smaller bodies of water like lake, ponds, and rivers but as it flows into a bigger body of water like the ocean the concentration becomes higher
Ocean zones - Intertidal (which shallow waters, exposed with low tide), Neritic (extended to 200 meters deep including continental shelf), Continental Shelf (The outmost edge before the deep open ocean), Benthic (the bottom of ocean/ocean floor)
Photic zones which include intertidal, Neritic, continental shelf, benthic are sunlight regions and Aphotic zones don’t receive sunlight
Lake zones - Littoral zone (shallow, shoreline enough light for plants to grow like coral reefs) and Limnetic zone (offshore, still receive enough sunlight but too deep for plants to grow)
Turbidity - the cloudiness of the water also affects the light penetration in lakes and oceans
water flow - Source of stream are usually clear, holds more oxygen and low nutrients compare to the open ocean or downstream where its low in oxygen and high nutrients with more turbidity
Turnover happens when the surface water becomes denser than the water at the bottom usually happens between the seasons
During fall and spring, the water at the top has more nutrients as the top with high oxygen at the bottom compared to winter whereas the oxygen is high at the top with the nutrients at the bottom
