Animal Responses Flashcards
Ecological Niche
The physical and biological conditions or factors a population faces in its habitat
Adaptive Advantages
Finding favourable environment Obtain Sufficient energy Reduce competition Avoid predation/herbivory Reproduction
Innate Behaviour
Genetically programmed behaviour (heritable, intrinsic, stereotypic, inflexible)
Learned Behaviour
Discovered behaviour as a result of experience through trial, error, observation and memory (non-inheritable, extrinsic, adaptable, progressive)
Taxis
Animal Response: Directional response involving movement towards (positive) or away (negative) from an external stimulus

Food
Desiccation
The removal of moisture
Dry out Dehydration Death
Kinesis
Animal Response: Non-directional/random movement in response to a stimulus in which the rate of movement is proportional to intensity of the stimulus
Klino (kinesis)
Rate of turning
Ortho (kinesis)
Speed of movement
Thigmo (kinesis)
A non directional response to touching something/random movement until something is touched.
Navigation
Innate behaviour using a range of sensory receptors (landmarks and natural compasses) to find way home
Migration
The seasonal mass movement of a population to a predetermined location
Homing
Inherit ability of an animal to return to original location (home/breeding territory) through unfamiliar areas
Tidal
Moon’s pull on bodies of water occurring twice in 24 hours
Lunar
Moon’s orbit of the earth, where one lunar month is 29.5 days
Annual
Earth’s orbit of the sun occurring every 12 months/one year
Circadian Rhythm
Endogenous daily rhythm with a free running period of 24 hours and are entrained by zeitgebers
Photoperiod
Hours of daylight
Diurnal
Active during hours of daylight
Nocturnal
Active during hours of darkness
Crepuscular
Active at dusk and dawn
Exogenous Rhythm
Biological rhythm driven by an external environmental stimulus
Endogenous Rhythm
Biological rhythm controlled by an internal clock
Zeitgeber
An environmental stimuli that resets the biological clock
Entrainment
The process of resetting the biological clock to match the environment
Phase Shift
When the onset of the period of the rhythm is changed either earlier or later
Calculating phase shift: hours / days
Free - Running
Biological clock is running under constant environmental conditions
