ecology examples
| species/topic | situation |
|---|---|
| Adaptation: Mangrove Trees | -Grow in saline, inter-tidal areas -Use aerial roots to gather oxygen from the atmosphere (pneumatophores) during low tide -Seeds germinate, begin to grow while still attached to the tree, are dispersed in the water |
| Adaptation: Dune Grass | -Long roots to stabilize dunes and absorb water from deep in the ground -Circular blades with pit to trap humidity and off set water loss from winds |
| Abiotic impacts: Cacti | -Thick stems store water -Reduced amount of leaves minimizes water loss due to excess heat |
| Abiotic impacts: Polar bear | -Thick layer of blubber for warmth -Thick fur for warmth |
| Abiotic impacts: Fennec foxes | -Large ears reduce body heat -Nocturnal to avoid sun |
| Adaptation: Sloths | -Move slowly to conserve energy since they eat low energy foods -Special tendons to grip trees -Slow movement avoids detection from predators |
| Adaptation: Bromeliads | -Have broad leaves to catch sunlight through the canopy (they're short) |
| Mixotrophic nutrition | -Euglena -Zooxanthellae in coral |
| Fundamental niches v. Realized niches | -Gray v. Red squirrels -Big v. Small barnacles |
| Changing ecosystems | -Saudi Arabia, Sahara used to be rainforests |
| Stable ecosystems | -Daintree rainforest in Australia is older than the dinosaurs |
| Keystone Species: Yellowstone Wolves | -Reintroduces to the park in the 90's after being hunted to extinction -Controlled the overpopulated elks -Restored damaged plant populations -Changed course of the river |
| Rewilding: Hinewai reserve, New Zealand | -Stopped grazing -Reduced human activity -Removed non-native species -Reintroduced apex predators and keystone species |
| Conservation methods | -Zoos, botanical gardens -Nature reserves, rewilding -In situ conservation |
| Climate change: Emperor Penguins | -Breed on landfast ice -Forced to move inland due to melting ice -Disrupted breeding kills hundreds of chicks |
| Climate change: Walruses | -Melting ice forces them to rest on nearby islands -Islands become overcrowded, cause excess competition |
| Upslope range shifts: Montane Birds | -Montane birds in Papa New Guinea are moving to higher altitudes for more favorable conditions |
| Poleward range shifts: Oak Hickory Tree | -Oak Hickory trees in the U.S are slowly moving northward since that's where their seeds are surviving |
| Phenology: Arctic Chickweed | -Due to changes in temperature, arctic chickweed is growing earlier in the spring in Northern Canada than it should -Reindeer return at their normal time, unable to eat the chickweed that's already been growing |
| Insect Life Cycles: Spruce Bark Beetles | -Rising temperature increase the amount of insect life cycles within a year -Increase amounts of spruce bark beetles growing within trees can devastate forests |
| Evolution impacted by Climate Change: Tawny Owls | -Brown morphs becoming more dominant over gray ones since they are better camouflaged in summer environments |
| Extinct Species: Giant Moas | -Used to live in New Zealand -Hunted to extinction by humans thousands of years ago |
| Extinct Species: Caribbean Monk Seal | -Hunted to extinction by European colonizers a few hundred years ago |
| Endangered Species (local): Alpine Ipex |
