4 Flashcards
Phenolic ring?
A 6 carbon benzene ring with an attached hydroxyl group.
Aliphatic compound?
Organic compound containing carbon and hydrogen usually linked together in chains via single, double, or triple bonds.
semiochemical?
Chemical substances produced by plants or animals, for a physiological response or behavioural response of the recipient.
Pheromones?
Chemical interactions between organisms of the same species (intraspecific)
Bell peppers was bred to get rid of?
Capsicum
Can you assume that if the directed deterrence hypothesis holds and the deterred groups are deterred, that they are bad quality dispersers?
No, you cannot assume.
So in additional to directed deterrence hypothesis, what must you show?
That the two different groups have opposite effects for the plants to alter plant fitness.
The longer seeds stay in the gut of an organism, then they have increased or decreased germination success?
Increased
Capsicum may facilitate what else in birds?
Gut retention
Disperser fidelity?
You can have chemicals that filter for the pest pollinator out there, and it keeps away the predators and other negative effects.
Defensive trade off?
If you are very well defended against one thing, you may pay for that by not being defended by another thing.
How many functions could chemicals proceed by organisms have?
They can have many functions, multifunction
Alkaloids in agriculture is commonly used as an?
Insecticide
What were some of the surprising findings of capsicum?
It is apparently anti-fungal and effective antimicrobial.
When mean annual temperatures increase, the spices per recipe increase/decrease
Increase as well
More spices in food is a benefit for that?
Delays rotting
Ibogain?
Most efficient drug to treat addiction with other drugs, such as opioids and cocaine.
Semiochemical communication can be divided into two broad classes?
Communication between individuals of the same species (intraspecific) or between different species (interspecific).
Hormone?
Chemical triggers used within individuals
Pheromone?
Chemical signals/effects between intraspecific species, produced by exocrine glands.
Releaser pheromone?
Chemical signals emitted by an organism to evoke immediate behavioural response in members of the same species.
Primer pheromone?
Chemical signal released by an organism that induces relatives long-term physiological changes in a recipient of the species.
Allelochemical?
Chemical signals /effects between species (also semiochemicals)
Allomone?
A chemical substance that is beneficial primarily to its producer (defences or predator that lures prey).
