Behavior Flashcards
What were Tinbergen’s four questions?
- What stimulus causes a behavior, and how does an animal’s physiology allow for a response?
- How do experiences influence behavioral responses?
- How does the behavior affect fitness?
- What is the behavior’s evolutionary history?
Define
Proximate causation
“How” the behavior happens
Define
Ultimate causation
“Why” the behavior happens (think: evolution!)
List characteristics of a
Fixed action pattern
- Unlearned / innate to the animal
- Unchangeable
- Once started, is carried to completion
What leads to a fixed action pattern?
A sign stimulus
Define
Migration
Regular, long distance changes in location
What are two common ways animals “know” directionality for migration?
By comparing their position relative to either
* the sun, or
* Earth’s magnetic fields
What are three common behavioral rhythms?
Circadian
Circannual
Lunar
What helps establish circadian rhythm?
Light and dark cycles
What helps establish circannual rhythms?
Day length
What activities are commonly mediated by circadian rhythm?
Rest and daily activity
What activities are commonly mediated by circannual rhythm?
migration and reproduction
What are four modes of communication?
Visual
Chemical
Tactile
Auditory
What determines the type of communication in a species?
Its lifestyle and environment
Example: visual cues are rare in nocturnal animals
Define
Communication
Transmission and reception of singles between members of the same or different species
