Cheat Sheet for Biological Oceanography Midterm
Planktons: groups of tiny floating organisms that cannot swim against the current.
*Taxonomy: size, function, autotrophs-producers, heterotrophs-consumers/decomposers, mixotrophs, complex, symbiotic/parasitic
*Small to big: femtoplankton (viruses), pico (bacteria), nano (diatoms, dinoflagellates), micro(sameasnano+protozoa), meso(mostly zooplankton), macroplankton
*Grazing food chain: Phyto->zooplk->fish *Sinking flux: dead fall to deeper ocean
POM: Particulate organic material DOM: dissolved organic material *Microbial Loop: see picture 1
Collection methods of plankton: Epi-fluorescence microscope, flow cytometer, scuba, submarine, bioacoustics methods
Phytoplankton: red tide=dinoflagellate bloom ONLY Trichodesmium can fix N_2
Radiolaria-amoeboid protozoans (omnivores) Ciliates- use cilia for locomotion heteropods-mollusca more examples
Meroplankton: Holo=planktonic whole lives Mero=Juvinile is planktonic Larvae: veliger-larvae of benthic snails and clams; veler: ciliated membrane
Nauplius from barnacles: six stages planktonic forms; then succeed to Sypris stage which settle down and metamorphose; then adult stage
Ichthyoplankton- collective term for fish eggs and larvae Spawning and hatching usually are tied to temperature and food (phytoplankton) cycles
Biological Pump: CO_2 sinks to bottom of the ocean to get pereserved there
Major species of algal bloom: diatoms, dinoflagellates, coccolithophores, etc. blooms are unsteady phenomenon
Bloom definition: cell #’s >10^6mL^-1 chlorophyll a concentration ? 3-fold of the annual average.
Geosphere, Lithosphere, Atmosphere, Hydrosphere, Biosphere Gaia Hypothesis – (James Lovelock) The chemical constituents within the Earth System are out of equilibrium in a thermodynamic sense. Such “dis-equilibrium” is maintained by the living biosphere. (In other words: The earth is a living system, it can adjust itself.)
Microbial loop is: DOM->
