Document Summary
Natural history- the study of how organisms in area particular are influenced by factors such a climate, soils, predator, competitors, and evolutionary history. Daniel janzen did a study that showed slots, camels, and horses would disperse the guanacaste seeds. 500 years ago europeans introduced horses and cattle who ate fruits of the. Guanacaste tree and dispersed its sees around the landscape. Past and present now domestic livestock expend for its dispersal. Biomes- are distinguished primarily by their predominant plants and associated with particle climates. Uneven heating of the earth"s spherical surface by the sun and the tilt of the earth on its axis combine to produce predictable latitudinal and seasonal variation in climate. Most of the earth"s climate variation is caused by the uneven heating of its surface by the sun. This seasonal change occurs because the earth"s axis of rotation is tilted approximately 23. Also the shape of the earth cause uneven heating.
