Fingered Poison Frogs are endemic to Trinidad. Females deposit small clutches of eggs in terrestrial nests. After hatching in July, one of the parents
transports the tadpoles to a small water body, where they complete their
development to metamorphosis.
Suppose that due to changing climate conditions small bodies of water are
only readily available during certain months of the year. In Southern
Trinidad, water bodies are only present during the spring months (April and
May) and in Northern Trinidad small bodies of water are only available
during the fall (September October). What type of pattern of natural
selection would we expect to see in Trinidad's Fingered Poison Frog
population with respect to time of reproduction?

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
