Excerpt: ... Biology 111, Principles of Biology Lecture Outlines ECOLOGY & ECOSYSTEMS ECOLOGY: the study of the interactions between organisms and their environment The environment includes both biotic (living) and abiotic (non-living) components The biotic components include all other living organisms with which a particular organism interacts: plants, predators, prey, pathogens, etc. The abiotic components include, temperature, climate, nutrients, soil, water, etc. Organisms are affected by their environment AND they also have a direct impact on the environment. Organisms consume nutrients and put out wastes. Consider the impact/effects of ABIOTIC factors : Temperature Climate Water Wind Rocks & Soil: (pH, nutrients, etc.) POPULATION ECOLOGY: Populations can be described in terms of several characteristics: Density: no. of individuals/unit area (or volume) Range: geographic area inhabited by a population Dispersion: distribution pattern of individuals with respect to one another (see Figure 35.2).

USF, ZOO 3205
Excerpt: ... ECOLOGY LAB (PCB 3043L) FINAL REVIEW QUESTIONS Fall 2007 Bring your calculators to the final! Handwritten notes are allowed. Formulas needed for the final will be on the final. Introduction What is ecology? How does it differ from environmental science? What are the different scales at which ecology can be studied? What do we mean when we say that ecology is interdisciplinary? What are some of the other disciplines involved? What are the different types of ecological studies? Could you describe them? If presented with an ecological question, could you design a study using each method to answer the question? When writing a lab report, what information should be presented in each section? Why do we use error bars on graphs? How do you interpret them? Abiotic Factors I Daphnia If given data, could you draw a tolerance curve and label the zones (this may include extrapolation)? Could you interpret a tolerance curve and suggest biological meaning for each of the zones? What is a physiological response? What are so ...

Bowling Green, EDHD 611
Excerpt: ... Notes will vary based upon individual class concept attainment. These notes will be modified with examples and more in depth information at the teachers discretion. What Shapes an Ecosystem? Section 4-2 Biotic and Abiotic Factors Biotic Factors are the biological, or living, influences on organisms within an ecosystem. - ex. animals, tress, plants, bacteria Abiotic Factors are the physical, or non-living, factors that shape ecosystems. - ex. climate, wind, soil type, sunlight Together, Biotic and Abiotic Factors determine the survival and growth of an organism and the productivity of the ecosystem in which the organism lives. The Niche A Niche is the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions. Community Interactions Community interactions, such as competition, predation, and various forms of symbiosis, can powerfully affect an ecosystem. A Resource is any necessity of life, such as water, nutrients, light, food, or sp ...

Upper lethal limit WAAAAY too much of the limiting abiotic factor and everything dies. To survive, organism must live somewhere between 2 and 4. To do really well, live in region 3. CONCEPT OF THE NICHE 6 We could add another abiotic factor (add multiple dimensions incorporating multiple abiotic factors ) CONCEPT OF THE NICHE 7 We call the entire set of conditions ("n-dimensional" space those abiotic factors ) where an organism could maintain a viable population (one that is growing and reproducing) the fundamental niche o Fundamental niche - The place in time and space (in terms of resources) where an organism has everything it needs to really grow. Important aspects of the fundamental niche: 1.) Niche may differ seasonally (bird may need different things in summer or winter) 2.) The niche may differ across the Life Cycle of the or ...
