Flashcards. 13.1 Ecologists Study Relationships. Organisms interact with physical environment Exchange of materials, energy with environment studied as fluxes Organisms maintain themselves in improbable steady-state relative to physical environment Major constraints of physical environment include properties of water, air, soils, temperature, and light, Introduction to physiological ecology Level of organization = individual organism Define physiological ecology: the study of the interaction of the organism with its physical environment, and its adaptations to that environment Physical environment not only necessitates adaptations for organisms to exist in particular environments, but it also constrains the distribution of organisms e.g., vampire bat, desmodus rotundus Its northern distribution = 10 C Jan. minimum isotherm (next slide), All organisms are constrained by physical, chemical environment (i.e., according to physical laws) Physical world provides window of conditions within which life can exist (e.g., temperatures at which water is in liquid state) Physical world also provides life-giving conditions: E.g., portions of electromagnetic spectrum --> ultimate form of energy for most life (all but deep sea, hot vent organisms) Soils and water contain various elements needed by living organisms (e.g., C, O, N, P, Ca, Na, Fe, Mg) Biological systems (e.g., organisms) interact with physical environment, Interaction with physical environment also implies alteration of it by organism E.g., Life first arose in a reducing atmosphere (<1% O2), but living things created an oxidizing atmosphere (ca.

Air less viscous, less buoyant than water (organisms move easily thru it, but need more support) Diffusion of gases much more rapid in air than water O2 diffuses rapidly in air (solubility 0.21 cm3/cm3 air); slowly in water (solubility 0.01 cm3 O2/cm3 water) O2 often limits organisms in water-saturated environments, especially where decay organisms (heterotrophs like bacteria) take up O2 This leads to anoxic conditions (like sulfur-stink of mucks in Lafitte Park) CO2,by contrast, is rare, often limiting, in air (0.03%); dissolves readily in water (carbonic acid, bicarbonate), Many plants tend to have great difficulty getting enough CO2, when stomata are open enough to transpire water; this is particular problem in desert environments (see next lecture), Chemistry of life Living systems based largely on chemical reactions of C, O2, H Plants use photosynthesis to convert carbon from oxidized form (CO2) to reduced form of organic carbon, e.g., sugars, starches, Reduction reaction less favorable energetically than oxidation--former requires energy from sun via chlorophyll molecules as energy-absorbers; energy of living things stored in reduced carbon bonds, e.g., carbohydrates, Respiration is reverse of photosynthesis Respiration involves coupled oxidation & reduction (redox) half reactions, the reverse of those in photosynthesis O2 + 4e- + C4+ = CO2; Reduction half-reaction (oxygen is reduced by gain of electrons) CH2O = C4+ + H2O + 4e-; Oxidation half-reaction (carbon is oxidized) Coupled together: CH2O + O2 = CO2 + H2O Overall reaction is favorable (net release of energy) because reduction of oxygen (top step) releases more energy than reduction of carbon; and oxidation of carbon (bottom step) releases more energy than reduction of oxygen requires, Temperatures of living things Temperatures of living things determined by range of temperatures at which water is in liquid phase Few organisms can survive temperatures > 45C, because of protein denaturation at high temperatures Some organisms can exist at higher temperatures due to particularly heat-stable proteins Most organisms cannot tolerate body (cell) temperatures below freezing, because of damage to cells from ice crystals Some organisms can exist at slightly lower temperatures using antifreezes such as salts, glycerol Increased temperature sets higher rate of chemical reactions (2-4 times increase in rate per 10C), Conclusions: We can learn much about the distribution and properties of organisms by understanding the physical environment in which they live Organisms cannot escape the physical-chemical laws of the universe, but to a limited extent they can evolve modifications that take advantage of peculiar conditions--well examine some adaptations of organisms next class, 2022 SlideServe | Powered By DigitalOfficePro, Physiological ecology: the physical environment, - - - - - - - - - - - - - - - - - - - - - - - - - - - E N D - - - - - - - - - - - - - - - - - - - - - - - - - - -. what is a bio-rhythm?.
