Document Summary
In which marine zone would you find the majority of plankton: benthic zone, pelagic zone, intertidal zone, abyssal zone. Find them in the surface of open oceans. How and why the # of individuals in a population changes over time. Environment is fine, but absent because species just never got there. Density: # individuals per unit area or volume. Organisms that don"t move: use transepts and measure every so meters. Organisms that do move: find proxies and use transepts for those (such as food, poop, etc. ) How are individuals space away from each other. We have to know the specific location of individuals: clumped - starfish. Resource-related: bat flies: uniform - territorial species (penguins) Resource uniformly distributed throughout the environment: random - flowers in a field. Dispersion patterns tend to be highly dependent on the spatial slace of the observer. Dispersion patterns can vary, depending on scale at which you look. Given a large enough scale, everything looks clumped.
