A southern European songbird, the blue tit, breeds in two habitats that differ greatly in quality.In deciduous oak forests, blue tits produce so many young that their populations have thepotential of growing at the astronomical rate of 10% annually. In evergreen oak habitats, blue titsperform poorly, with populations showing a potential for a rapid decline of 13% annually. Yetblue tits persist in both habitats. Why?
A student decides to use the mark-recapture technique to estimate thepopulation size of mosquitofish in a small pond near his home. In thefirst catch, he marked 45 individuals. Two weeks later, he captured 62individuals, of which 8 were marked. What is the estimated size of thepopulation based on these data?a. 134 c b. 349 c. 558 d. 1,016 e. 22,320

Background Information: Before the industrial revolution, the trees in the forest around Manchester, England were a light grey/green due to the color of lichens (fungus) on their trunks. Peppered moths, or Biston betularia, which lived in the area were found in two varieties: 1) Light with dark spots (most common) and 2) Dark with light spots (less common). Because there were not enough resources to support the entire population, the two varieties of this species had to compete for survival. Their coloring, when against a similar background, served as camouflage against predators such as birds and lizards, thus increasing chances of survival. As the Industrial Revolution progressed, the trees became covered with sulfur dioxide, which killed the light-colored lichen and thus turning the tree trunks dark. Problem Questions: Choose only 1 question below to answer in an “If…then” hypothesis. What will happen to the number of light-colored peppered moths as the trees began to darken?…
Two species have the same initial population size of 48.00, as well as rates of b = 0.83 and d = 0.66. However, species A reproduces seasonally and species B reproduces relatively continuously. How much bigger would the population of species B be after five years as compared to species A?
Organismsthat produce many offspring would best be characterized by which of thefollowing?a.A convex survivorship curveb.A concave survivorship curvec.A linear survivorship curved.A sigmoidal survivorship curvee.None of the choices apply
Meta population models focus on the BIDE (birth, immigration, death, emigration) dynamics, colonization and extirpation. A) Explain how these relate to genetic bottlenecks and explain why meta population models have a hard time predicting such events? B) Why is the island biogeography model a strong example of meta population dynamics?
What does the data suggest? What does anova P = .45 means? Could you explain the above details in this context Context - The study aims to test the role of priority effects in fruit fly communities. I tested whether the timing of one species arriving at a particular site causes any alteration to the environment, making it more or less desirable for a second species to come.
A large conservation agency in Austria is interested in the status of the endangered newt species, Triturus austriacus, and wants you to estimate population sizes. Describe at least two methods based on genetic markers such as microsatellites which could be used to estimate effective population size (NE). Compare their relative advantages and disadvantages.
The key finding ofl a study with butterflies and habitat fragmentation by Haddad and colleagues was a. Edge habitat is drier than the forest interior. b. patches connected by corridors sustained higher butterfly densities than isolated patches c. large patches hold more butterflies than small patches d. butterflies densitties were unaffected by the presence or absence of corridors
