- Choose all incorrect statement. In 2021, 23 species were declared extinct. Most of these have been presumed to be extinct for decades. Eight of the declared extinctions were bird species endemic to the Hawaiian Islands. One species declared extinct was the Molokai creeper (pictured). Main causes of their extinction include loss of suitable habitat, disease, and predation by introduced mongooses and rats. Avian malaria is transmitted between bird species in Hawaii by mosquitoes that were brought to the islands by ships many decades ago. Which of the following statements is NOT accurate? a.Avian malaria is a vector-borne disease; if it infects 90% of the birds regardless of bird population size, it is acting as a density-independent factor. b.Among vertebrates, bird population sizes have declined the most compared to any other vertebrate group. c.Eliminating invasive rats and mongooses from the Hawaiian Islands, like goats were eliminated from the Galapagos, could help prevent further…Question 2 Read the excerpt below regarding research at the University of Guelph: Light Pollution is key 'bringer of insect apocalypse' Light pollution is a significant but overlooked driver of the rapid decline of insect populations. Artificial light at night can affect every aspect of insects' lives...from luring moths to their deaths around bulbs, to spotlighting insect prey for rats and toads, to obscuring the mating signals of fireflies. Widespread declines [in insect populations] threaten to cause a catastrophic collapse of nature's ecosystems. Insects around the world are rapidly declining. Their absence would have devastating consequences for life on this planet. There are thought to be millions of insect species...and about half are nocturnal. Those active in the day may also be disturbed by light at night when they are at rest. The evidence that light pollution has profound and serious impacts on ecosystems is overwhelmingly strong. Light pollution could have significant…Based on the text on mosquitoes eating: 1. Identify abiotic factors that support the survival and reproduction of the mosquitoes and why the mosquitoes needs this factors. 2. Identify biotic factors that support the survival and reproduction of the mosquitoes and why the mosquitoes needs this factors 3.Predict what factors in the environment can be altered to decrease the survival and reproduction of the mosquitoes and why. PLEASE ANSWER ALL QUESTIONS
- Which row below best describes why the population of adult mosquitoes would drop so dramatically during this time period Feb. 5, 2007 Something is wiping out honey bees across North America and a team of researchers is rushing to find out what it is. What’s being called Colony Collapse Disorder (CCD) has now been seen in Pennsylvania, North Carolina, Florida, Georgia and way out in California. Some bee keepers have lost up to 80 percent of their colonies to the mysterious disorder. Whatever kills the bees targets adult workers, which die outside the colony — with few adults left inside, either alive or dead. The disorder decimates the worker bee population in a matter of weeks. Aside from making honey, honey bees are essential for the pollination of tens of million of dollars worth of cash crops all over the United States. That’s why almond growers of California, for instance, are taking notice and pledging funds to help identify and fight the honey bee disorder. Among the…Due to its ability to camouflage itself from predators, the White Peppered Moth of England was once much more abundant than the Black Peppered Moth. As the Industrial Revolution hit, factories began to release black soot which coated everything, including tree bark. Because the moths’ habitat was now darker, the white moth became much more susceptible to predators. At the same time, the Black Peppered Moth was now more protected and began to increase in number.This story is an example of A. natural selection. B. extinction. C. endangered species. D. mutation.forest sites than in forest fragments, whereas there were no significant differences between fragments of different sizes. These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.
- Below is a short research proposal. Review the proposal. Identify the research question, weaknesses, and propose changes as appropriate. Many butterfly species are known to have long migrations, with some species showing spectacular movements of millions of individuals. One of the ancient tropical species is the Monarch butterfly. Thought to have originated in the Mexican and Central American mountains and valleys, it eventually invaded warming northern regions driven by its search for its valuable food source, the milkweed plant. During the falls season, monarchs from Canada and the United States will start their longest journey known as “The Great Monarch Migration” to Mexico. How the Monarch can accomplish the 3000 miles journey is still puzzling. Your friend, a lepidopterist, wants to develop a proposal to understand how genetics influence Monarch’s ability to sense changing environmental signals aiding them to get to their destinations in the fall. She believes that the…Crown-of-thorns starfish (often abbreviated as COTS; Acanthaster planci) is one of the largest sea stars in the world. It is also well known as a voracious predator of corals. Sudden outbreaks or swarms of this one species can rapidly consume an entire coral reef. Use internet resources to investigate recent research articles on the topic of crown-of-thorns starfish outbreaks on coral reefs. Where do these outbreaks occur? What impacts do they have on near-shore ecosystems? What causes these outbreaks? What management practices, if any, could be employed in response to COTS outbreaks? Site your sourcesWhich of the following statements are true? a. ) Almost all invasive species are plants. b. Invasive species multiply rapidly and may displace native species in a community. c. Invasive species have no predators or parasites in their new ecosystem d. All introduced species are invasive. e. In sexual reproduction, the offspring have the same combinations of genes as their parents. f. Sequential hermaphroditism occurs when an animal is one sex during one phase of its lifecycle and the opposite sex during another phase
- Insects are the largest group of animals on Earth. Insect diversity is greatest in the tropics, where habitat destruction and species extinction are occurring at an alarming rate. What biological, economic, and ethical arguments can you advance to persuade people and governments to preserve this biological diversity? Instructions:A federal agency has put you in charge of devising responses to the invasion of zebra mussels and quagga mussels. Based on what you know from this chapter, how would you seek to control the spread of these species and reduce their impacts? What strategies would you consider pursuing immediately, and for which strategies would you commission further scientific research? For each of your ideas, name one benefit or advantage, and identify one obstacle it might face in being implemented.https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html Now you'll tie together what you've learned. Read over the information on what's happening with the study of lionfish (you can ignore the questions on this page). Answer the question here on Canvas. 18)Based on what you've learned about the invasive lionfish population in the Atlantic, and the various types of factors that may limit population growth, which ONE factor (intraspecific competition, interspecific predation, disease & parasites, social behavior) do you think would be the MOST limiting? Why?
