Front Back
Social communication
Between same species
Ecological communication
Between different species
Information
Stimulus that influences an individuals probability of a behavior
Uncertainty
Information variable, increased information=decreased uncertainty about recipiant's probability of said behavior
Cue
Environmental change that has information (seasons, heat, day length..)
Signal
Behavior act that conveys information (incidental vs displays)
Displays
Adaptive and evolve from Natural Selection. more specific signal modified to enhance information transfer through ritualization
Ritualization
Process of evolution of displays from incidental signals (mating calls, antipredator alarm calls and alerting, aggression)
Four types of ritualization
Enhancement (add something) , exaggeration (building on something) , sterotypy (low variance within individuals or low variance among individuals) , repetition (again and again). NOT MUTUALLY EXCLUSIVE
Foraging on plants
Herbivory (predatious), pollination (cooperative), seed dispersal (mutualism)
Coevolution
One species evolves in response to evolution in another species which in turn makes the other species evolve in response... arms race (cyclical)
Defenses
Constitutive (always present, permanent part of body stucture), inducible (show defense when predation imminent/behavior components)
Aposematism
Warning about honest communication to predators
Mimicry
Mullerian (defended species resemble each other) , Baysian (defended species (often aposematic) are resembled by undefended species)
Optimal foraging theory
Assuming that foraging is optimized by evolution under natural selection, we can test what costs and benefits (proxies for RS) are important in explaining a given species' foraging behavior. OFT is used to generate models and predictions about foraging behavior, based on the key assumption that natural selection maximizes the efficiency of foraging
