Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources. how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring?

For the most part the birds will be negatively affected by the early spring, they won't have the food they need and because they missed finding ideal nesting spot one of two things will happen, they will either pick an unsafe nesting area which can result in their young being hurt or even themselves, and/or they won't breed at all and because of this the Warbler population will decrease due to low mating rates. Eventually, the birds will evolve in a way and start coming back from their migration earlier than previous generations and thus they will have access to the food and nesting areas that they need and the population will spike again.

I hope this helps you out a little!

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
