Ohia Lehua
What is Metrosideros Polymorpha
100
It is the dominant species in the forest that keeps the ecosystem together.
What do we mean when you say Ohia lehua is a 'Keystone Species'?

Mesic
What ecosystem has the most endemic plants?
100
Selective pressures
Human beings, viruses, wind, rain, water, sunlight, all can affect a way a species evolves, hence they are what....

1. Coastal = 15-30 inches 2. Dry Forest = 30-40 inches 3. Mesic = 40-100 inches 4. Wet Forest = 100-450 inches 5. Rain Forest = 100-450 inches 6. Bog = ~400 7. Alpine = ~ 400in.
What is the rainfall of each of the following zones? 1. Coastal 2. Dry Forest 3. Mesic 4. Wet Forest 5. Rainforest 6. Bog 7. Alpine

Mamaki in the Wet forest
What is Pipturus albidis and what ecosystem can you find it?
200
ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period Primary succession occurring over time. The soil depths increase due to decomposition of plant matter and there is a gradual increase of species diversity in the ecosystem.
What is primary succession? and how does it relate to the Ohia lehua?
200
Pigs, invasive weeds, disease, insects, rats
What threatens bogs?

Adaptive Radiation is a fast evolution where multiple species derive from one origin species over a shorter period of time. Gradualism: Is a longer process than adaptive radiation in which there is a slow change in a species and few over time from a single one.
What is the difference between adaptive radiation and gradualism?

Coastal: Dry, minimal Rainfall, Salty, windy, creeping plants Dry Forest: Dry minimal Rainfall, lots of sunlight, fire hazard, bugs. Alpine: High elevation, cold, windy, snow, little plants up
What are some characteristics in environments like in Coastal, Dry Forest and Alpine Zones?
