animal
org that feeds on org matter, usually has specialized sense organs and nervous sys, able to respond rapidly to stimuli
whooping cranes clip
birds on the verge of extinction, so because chicks imprint on caregiver, ppl taking care of them have to wear crane costumes. young learn migration from adults

what does the spontaneous improvement curve look like
downwards s curve
house finch experiment, ch 3
steroid hormones
fat soluble hormones that need chem carrier -> longer time between when stim sensed and hormone release
HPA axis
hypothalamic-pituitary-adrenal axis, activation = behaviour changes
fight or flight process
prairie voles vs meadow voles, ch 3
prairie voles r monogamous and better dads bc more vasopressin receptors in ventral pallidum area
meadow voles r polygynous and deadbeats bc they have less vasopressin receptors
vasopressin controlled by avpr1a, homozygous long avpr1a = more sweet and kind -> for prairie voles
honeybee foragers and nurse bees, ch 3
at 21 days some bees become foragers bc they have more JH III in corpus allatum
- remove corpus allatum = start foraging later and shittier at it
- foragers have more octopamine and bigger mushroom bodies/corpora pedunculata
plainfin midshipman fish
type i: smaller dicks, bigger muscles w more fibers, mate normally, arginine vasotocin inhibits sound prod
type ii: bigger dicks, smaller sonic muscles w less fibers, sneaker males, isoctocin inhibits sound prod
puzzle box exp, ch 3
bigger brain size relative to body size = better problem solving
major components of behav
feeding fleeing fighting fornication
animal life history
survival growth reprod aging
tinbergens types of questions
DMSE: dev, mechanism, survival value, evol history
foundations of animal behav
nat select, indiv learning, cultural transmission
information-center hypothesis
foragers learn abt location and identity of food from other foragers that recently came back from a foraging sesh
what mechanisms change other bio traits
evol, phenotypic plasticity, growth/aging
curly tailed and brown anole lizards, ch 2
curly tailed eat brown anoles. they put curly tailed on islands where brown anoles were and their pop halved. kaboom hurricane killed more brown anoles. they moved to higher habitats, selected for bigger brown anoles.
domestication syndrome
domesticated species share common traits → mottled colour, floppy ears, curly tails, more juvenile, less neural crest cells.
3 prereqs of natural selection
variation in trait, fitness conseqs, mode of inheritance
truncation selection
