Kairomones
|
Benefits the reciever, other species
|
|
Allomone
|
One that benefits the releaser
|
|
Synamones
|
Tree releases chemical to keep certain things away, but also benefits parasitoids (benefit both receiver and releaser)
|
|
Pheromone
|
Functions within species, releasers—immediate behavioral response, and primers—alter physiology, more subtle
|
|
Mate attraction pheremone
|
Produced by female usually, designed to attract males from a distance. unique blend of chemicals
|
|
Courtship pheremone
|
Closeup stimulation during courtship, initiates mating behavior; time specific
|
|
Anemotatic response
|
Not on a concentration gradient, broken up clumps of pheromones. Males move up wind to the female. Fly across the wind
|
|
Advantages in pheremone comm.
|
Energetic efficiency
energetically cheap
easy to broadcast
can transmit darkness
|
|
Disadvantages of Chemical
Communication
|
Slowness of transmission
problem of fade out
|
|
Slow transmission
|
Rely on
diffusion and air currents, light or sound travels much faster
|
|
Problem of fade out
|
Signal lasts
certain finite time
|
|
Active Space
|
Area or space where the concentration
of a pheromone is above the threshold
for response
|
|
Size of the Active Space
|
Type of material and its volatility
amount released
behavioral threshold
environmental factors
