How Monarchs Know When to Migrate

The monarch butterfly is a true miracle of nature. Its the only butterfly species known to complete a round-trip migration of up to 3,000 miles each year. Each fall, millions of monarchs make their way to the mountains of central Mexico, where they spend the winter hunkered down in the oyamel fir forests. Just how do the monarchs know when its time to migrate? Differences Between Summer Monarchs and Fall Monarchs Before we tackle the question of what makes a monarch migrate in the fall, we need to understand the difference between a spring or summer monarch and a migrant monarch. A typical monarch lives just a few weeks. Spring and summer monarchs have functional reproductive organs soon after emergence, allowing them to mate and reproduce within the constraints of a short lifespan. Theyre solitary butterflies that spend their brief days and nights alone, with the exception of the time spent mating. The fall migrants, however, go into a state of reproductive diapause. Their reproductive organs arent fully developed after emergence, and wont be until the following spring. Rather than mating, these monarchs put their energy into preparing for the arduous flight south. They become more gregarious, roosting in trees together overnight. The fall monarchs, also known as the Methuselah generation for their extended lifespan, need lots of nectar to make their journey and survive the long winter. 3 Environmental Cues Tell Monarchs to Migrate So the real question is what triggers these physiological and behavioral changes in the fall monarchs? Three environmental factors influence these changes in the migrant generation of monarchs: the length of daylight, the fluctuation of temperatures, and the quality of milkweed plants. In combination, these three environmental triggers tell monarchs its time to take to the skies. As summer ends and fall begins, days grow gradually shorter. This steady change in the length of daylight helps to trigger reproductive diapause in late-season monarchs. Its not just that the days are shorter, its that they keep getting shorter. Research at the University of Minnesota showed that monarchs subjected to a constant but short amount of daylight would not go into reproductive diapause. The daylight hours had to vary over time to cause the physiological change that makes a monarch migrate. Fluctuating temperatures also signal the change of seasons. Although daytime temperatures may still be warm, late summer nights become noticeably cooler. Monarchs use this cue to migrate as well. University of Minnesota scientists determined that monarchs reared in a climate of fluctuating temperatures were more likely to go into diapause than those reared at a constant temperature. Late season monarchs that experience changing temperatures will suspend reproductive activity in preparation for migration. Finally, monarch reproduction depends on an adequate supply of healthy host plants, milkweed. By late August or September, the milkweed plants begin to yellow and dehydrate and are often covered with sooty mold from aphids. Lacking nutritious foliage for their offspring, these adult monarchs will delay reproduction and begin migration.

The Social Responsibility Of Business Essay - 1959 Words

1.) Do you agree or disagree with the following quotation: â€Å"There is one and only one social responsibility of business—to use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the game, which is to say engages in free and open competition, without deception and fraud.† Milton Friedman, a Nobel Prize winning economist. In other words, the social responsibility of business is to make a profit. I do not agree with the following quote by Milton Friedman. Engaging in activities that are designed to only increase profits for a company would open doors to complications and mistakes, which is caused by the lack of customer satisfaction. The social responsibility of any business should be to take care of its customers, instead of just focusing on the amount of profit the company is making. If a company decides to just focus on making a profit, it will lose focus on providing customers with products and services that will improve their standard of living. Based off of Archie B. Carroll’s global corporate social responsibility pyramid, doing what is profitable or what is required by global capitalism is the base of the pyramid, whereas being a good global corporate citizen and doing what is desired by global stakeholders is at the top of the pyramid.
