Last 3 weeks of material Flashcards
chromatography
the process of separating and identifying compounds from a mixture of substances
mass spectroscopy
analyze mass-to-charge ratio of charge particles to separate compounds by ions
Chemosensation
the perception of environmental chemical compounds and the subsequent processing of this information
olfactory sensilla
protect the dendrites of olfactory sensory neurons within sensillar lymph
Steps in Olfactory Coding
1.) Individual odors can activate multiple receptors
2.) Individual receptors can detect multiple odors
3.) Receptor response can vary base on odorant concentration
4.) Receptor response duration can vary based on odorant identity
What are the chemical cues driving pollinator feeding preferences?
Signal -> Perception/Processing -> Behavior
classes
share attributes, like population or species
instances
are individuals in a class, and can vary their attribute values
attributes
are changeable traits that can influence future outcomes
individuals can…
influence each other’s behavior
optimal foraging theory
Natural selection resulting in foraging
behavior that maximizes resource collection
and fitness.
marginal value theory
A strategy that maximizes gain per unit time
in systems where resources and thus rate of
returns decrease with time.
Trapline Foraging
When an organism follows a similar path
when foraging, making minor changes over
time.
personality, or behavorial type
consistent, long term behavioral differences between individuals
behavioral syndrome
consistent and/or correlated
behaviors
coping styles
how an animal
handles stress in the
environment
Dimensions of Personality
- consistent behavior over time
- consistent behavior across context
- behavioral syndrome
boldness
a pattern of behavior involving risk-
taking, both in familiar and unfamiliar
situations
shyness
a pattern of behavior involving
reluctance to take risks or engage in
unfamiliar activity
repeatability
when the variation within
an individual’s behavior is significantly
less than the variation between
individuals
epigenetic
environmental
influences that can have long
term, even trans-generational,
effects on phenotype
game theory
a mathematical tool; when
the payoff that an
individual receives for
undertaking an action is
dependent upon the
behavioral responses of
others
producers
search out
and discover new food
sources
scroungers
follow producers and feed
from food sources they
have uncovered
