BIOLOGY 2F03 Lecture Notes - Experimental Forest, Chlorophyll, Evolutionary Ecology
Document Summary
What is ecology: branch of biology that deals with the relations of organisms to one another and to their physical surroundings. Can several species use the same resource (macarthur): possibility that they cannot coexist. Different species of warblers feed in different places on the tree. Lessons: division of resources takes place as postulated, resulting from competition, as a result competition is reduced, aggression one of mechanisms, ex. Where black-throated green warblers are absent yellow-rumped warblers move their feeding zone upwards. Points: division of resources ceases as expected, the remaining species is released from competition, its habitat expands and abundance can grow. Photosynthesis, nutrient capture or release, other organisms (including plants: epiphytes) sometimes research requires some risks or focuses on large scale processes; e. g. hubbard brook , experimental forest in new hampshire, discovery of acid rain. Example of studies: hubbard brock experimental watershed in new.
