the largest population size that can be sustained by the available resources
once it's at its smallest amount the population levels off, leads to competition bc every individual needs it
competition between individuals of the same species
some individuals use up a resource before others can
individuals guard/defend a resource and prevent others from using it
competition between species
superior competitor excludes inferior one from an area
slightly different predators/tolerances/etc allows coexistence, lowers superior's strength over inferior
one organism feeding on another, closely linked coevolution
larger = host, smaller = symbiont
(+/0) i.e. barnacles on whales
(+/+) i.e. fish eat algae off turtles
(+/-) i.e. copepods on salmon
feed on nutrients from blood of fish, common
external, on gills or skin, sucker at both ends, not too problematic
internal, larger, in digestive system or body cavity
tapeworms, scolex is the structure that attaches to the host
internal, roundworms
big, external, usually on outside or gills, common on butterflyfish
external, on skin/fins/gills
the net export of fishable biomass out of an MPA
net movement of eggs and larvae out of an MPA
the goal of locating MPAs in areas with eddy currents
the goal of locating MPAs in areas with flushing currents
larvae that feed on plankton/detritus
larvae that are non-feeding
no planktonic phase, young hatch from egg into immediate environment, no dispersal
usually in a brood chamber in parent, eggs have sufficient yolk, egg number limited by space
affected by spawning behavior of adults, duration of pelagic period, larval behavior and growth
affected by reef fish larvae exhibiting depth preference, most avoid surface, depth preference changes with life stage
before tail changes position
after tail changes position, become better swimmers
number of species in a location
when species richness takes abundance into account
a genetic signature and measure of biodiversity
most common index, H=0 means 1 species, higher H = more diverse, assumes youve sampled every species in an area
Aaron's favorite index, assumes random sampling
calculates the probability any 2 individuals are the same species, expressed as 1/D
calculates the proportion of the sample accounted for by the most common species, expressed as 1/d
statistical measure that eliminates bias
older more stable environments support more species than younger and more disturbed ones
species diversity is maximized when disturbance is at an intermediate level
any behavior that takes place at regular intervals, usually synched with external cues
the study of biological rhythms
the length of time to repeat 1 rhythmic cycle
period about 24 hours
period less than 20 hours
period greater than 28 hours
magnitude of the variable from the baseline, in a cue's absence this decreases
any instantaneous repeatable state of the cycle like peaks/troughs
behavior continues without the cue
how much the earth reflects, ice loss decreases this
