Ecology: Definitions Ecology: The scientific study of the interactions between organisms and their environment that determines the distribution and abundance of organisms Ecology is a science Environmentalism is a cause Conservation Biology is the integration of these two: using science to support a political cause Population ecology: experimental field approach: natural populations manipulated to test specific predictions arising from controversial ecological theory Organismal ecology: studies how an organism?s structure, physiology, and (for animals) behaviour meet environmental challenges Population: all the individuals of the same species within an ecosystem Population ecology focuses on factors affecting how many individuals of a species live in an area

Bio 112, April 26 2013 Transition for competition to other aspects with in populations. EVOLUTIONARY RACE TO ARMS!!!! Evolutionary Responses -Predator- Prey interactions -Defensive adaptations of prey lead to offensive adaptations of predators -coloration, speed, eye sight, its a back and forth between these populations. -Red Queen Hypothesis (Leigh Van Valen) -evolving as rapidly as they can but not going anywhere. Stay in the same positions in the food chain. -Plant- Herbivore Interactions -Passive defenses -Chemical defenses that plants have in place all the time. Toxic!!! bad taste. -Lower population, be a rare species. -be habitat colonizers, rapid growth and re-populate new areas only. -Physical defenses, such as thorns.

Environmental Science Vocabulary ? Living Things in the Environment & Populations organism - a living thing habitat - an environment that provides the things an organism needs to live. biotic factor - a living part of an organism?s habitat. i.e. grass, plants, seeds, fruit, worms, bacteria, other animals abiotic factor - a non-living part of an organisms habitat. i.e. water, sunlight, oxygen, temperature, soil photosynthesis - the process in which plants use water along with sunlight and carbon dioxide to make their own food. species - a group of organisms that are physically similar and can produce offspring. population - all the members of one species in a particular area. The ?count? of one species in an area.

Ecology Study Guide Notes Chapter 50: Intro to Ecology The Scope -3 main questions: Where do they live? Why do they live where they do? How many are there? -Ecology helps reveal the richness of the biosphere and helps humans understand how to protect that diversity and richness which is now under attack. 50.1 Ecology is the study between organisms and the environment - Naturalists began studying organisms in their environment. Humans have also had need to know about organisms for hunting and gathering. - Ecology is very much an experimental science (field experiments). The difficulty to provide consistent results has resulted in many innovations regarding experimental science. Ecology and Evolution
