Morgan's Canon
|
in general if there is a simple explanation, it is the correct one
|
|
1. Causation
|
behavior is a response to stimuli, can depend on animals internal state
|
|
2. development
|
behavior changes throughout orgs life span
|
|
3. survival value
|
day to day survival (H2O, food, sexual survival)
|
|
4. evolution
|
modifications on pre-existing actions
|
|
ethology
|
study of animal behavior in natural environments
|
|
umwelt
|
how the animal senses the world around it
|
|
Juvenile hormone
|
regular development, reproduction, and behavior in arthropods. role of mating, pheromone secretion and parental behavior
|
|
Ecdysone
|
neg molting and prepro in arthropods
|
|
ecotype
|
genetically differentiated pop within spp adapted to a particular habitat
|
|
common garden
|
orgs maintained in equivalent environment while observed for differences, helps separate environment from genes
|
|
QTL (Quantitative trait locus)
|
a gene that contributes with other genes to a phenotype. multigene trait
|
|
heritability
|
proportion of phenotypic variance due to genetic variance
|
|
epistasis
|
dominant allele in determining the effect of a locus. variation due to dominance
|
|
quantitative trait analysis
|
continuous tait, number of genes acting together
|
|
drive theory
|
postulates that animals have a store of drive energy that is expended when a task is preformed (internal motivation to complete a task)
|
|
time budget
|
how an animal divides its available time among activities
|
|
feedback loop
|
animal continually assess condition and modifies beh to achieve targeted condition
|
|
displacement behavior
|
release of drive energy in an irrelevant task when wanted behavior is not possible (grooming)
|
|
redirected behavior
|
direction of beh to a third party or inanimate obj
|
|
self directed behavior
|
preformed on self typically due to stress or boredom
|
|
repetitive behavior
|
pacing ect, pathologies from displacement or redirection of energy when desired task is impossible
|
|
circadian
|
24 hour rhythm
|
|
zitgeber
|
time giver. external cue that tells time of day, can help rsync to new time zone/circadian rhythem
|
|
transition matrix
|
quantifies the actions of one animal in an interaction and the resulting response
|
|
ethograms
|
inventories of behaviors preformed by a defined group of animals
|
|
Sign Stimulus
|
an external sensory stimulus that triggers a fixed action pattern.
|
|
Prolactin
|
Inhibits sexual behavior, and increases production of crop milk
|
|
Opsins
|
transduction of light energy
|
|
nociceptor
|
pain receptor

|
Narrow sense haritability
|
based on additive genetic variation
|
|
pineal gland
|
light sensitive gland in brain
