| 31. | His work on locally adapted plant populations led him to coin the term " ecotype " in 1922.
|
| 32. | He used the plants in the archipelago as a laboratory to study evolutionary processes in small plant populations.
|
| 33. | Know what you are picking and never remove more than 10 percent of a plant or plant population.
|
| 34. | The reproductive core of the plant population is the area in which sexually mature parental plants are present.
|
| 35. | They were able to adapt to the shifting climate and the resulting change of animal and plant populations.
|
| 36. | These two major forces compete and change through time causing advances and retreats in the borders of plant populations'regions.
|
| 37. | Seed masting is an example of how plant populations are able to temporally regulate the severity of seed predation.
|
| 38. | Inbreeding is a serious threat, as the small plant population must reproduce within its own circle resulting in genetic defects.
|
| 39. | However, in grassland habitat the seed predator had little effect on the plant population because it was safe site limited.
|
| 40. | _If enough nitrogen is added, it pushes the ecosystem into increasingly chaotic oscillations culminating in a crash of plant populations.
