Assignment:
Queen termites produce a pheromone to control the division of labor in their colonies.
- Explain what a pheromone is.
- What is the role of the Queen's pheromone?
- Explain (specifically and in detail) how gene expression and regulation is involved in the control of reproduction in termites
Honeybees live cooperatively and have a strict division of labor. For example, some honey bees are foragers and some remain in the colony and help nurse larvae. What skills would a forager need to have to be good in their role? And explain the evidence to support the claim that foragers are predisposed for their role? Be specific and detailed!
Animals learn in many different contexts, including - but not limited to - (1) foraging (what to eat?), (2) habitat selection (where to live?), (3) predators (what's dangerous), (4) reproduction (who is a good mate?), (5) family (how to behave towards genetic kin and other conspecifics?). Select three of the five contexts above: for the ones you've selected, explain (using specific examples) the ways in which animals learn in and from their environments.
A. Explain the potential benefits to animals in light of adaptive mechanisms to evaluate very small differences in genetic kinship relationships (for example, distinguishing at the level of r= 0.5 and r=0.125). B. Based on the parent-offspring-conflict model, explain what differences in weaning behavior might be expected from younger mammalian mothers compared to older ones.
Design an animal behavior experiment that would help you distinguish cooperation as a result of byproduct mutualism from cooperation as a result of reciprocity.
Imagine you are studying a group of amphibian species that vary in their habitats, some living in dense, murky water and others living in very clear ponds. What kind of communication problems exist in each environment? What differences in communication systems would be expected across the species given the habitat differences?
In class we discussed the impact of anthropogenic effects on animal behavior. Select three (3) of the following examples and carefully explain each of them, being sure to indicate how the behavioral change may be impacting or might impact the lives and survival of these animals and their species.
- Symmetry and environmental stress
- Predation and ocean water chemistry
- Dispersal and environmental cues
- Personality and conflict
- Play and environmental stress
- Parental care, loss of habitat and migration
- Stress hormones and human presence
