To suggest: A way in which crane behavior might be used to ensure the safe passage of the birds to overwintering sites. Introduction: Bird migration is a seasonal phenomenon in which birds fly over long distances to find favorable ecological conditions for feeding, breeding and laying the eggs. Once the conditions at the breeding ground become unfavorable due to extreme winters, the birds fly back.

Which of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.

For various reasons, some species prefer to live on the edge of a habitat patch while others fare better if they stay near the middle of a patch. In areas with a mosaic of grassland and woodland, warbler fledglings are more likely to survive when their parents nest in the core rather than the ecotone, because the ecotone is also habitat for brown-headed cowbirds. What is the name for the behavior of cowbirds that poses a risk to warblers? Give typing answer with explanation and conclusion

A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs. How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light Temperature Day Length Springlike Springlike conditions listed below. Springlike Summerlike Summerlike Springlike Summerlike Summerlike In each of the four environments, one of the caterpillars was fed oak…
