Since 2000, three mammal species have been declared extinct by the IUCN: the Bramble Cay melomys (Melomys rubicola), Christmas Island pipistrelle (Pipistrellus murrayi) and the Saudi gazelle (Gazella saudiya). What is the extinction rate of mammals, in MSY, since 2000 (+/-0.01)? Assume for our purposes that 5,436 mammals have been monitored over the past 20 years.

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…

1) Many organisms have the ability to reproduce asexually as well as perform sexual reproduction. A Scientist, John Smith, was conducting research on aphids that can undergo both methods of reproduction. He determined the males in his population had fertilization rate of 1.8 and a relative fitness of outcrossed offspring was 1.1. a) What is the equilibrium frequency of males in this population? b) Is this population stable equilibrium and why?

https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step.   6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of these

Based on the biological species concept, which of the following would lead biologists to conclude that different populations of lizards were actually a single species rather than two different species? A.) lizards from the two different populations mate rarely, and produce hyrbid offspring that are sterile B.) Lizards from the two differnt populations mate during different seasons  C.) Lizards from the two different populations mate regularly and produce sterile offspring D.) Lizards from the two different populations matre regularly and produce viable offspring capable of reprod

Imagine there's a population of Cichlid fish living in a lake in East Africa. Some of the fish have a genetic predisposition to feed from the deeper parts of the lake and also enjoy breeding down there, while the other fish have a genetic predisposition to feed near the surface and enjoy breeding up there. Eventually, individuals from the upper parts of the lake stop breeding with individuals from the bottom because their hybrid offspring have poor fitness (and can't competitively feed at the top or bottom of the lake). These two sub-populations will likely experience and possibly evolve into two species. Genetic Drift Post-zygotic Isolation Directional Selection O Disruptive Selection

The type III survivorship curve is found in species in which most individuals die when they are young but a relatively small number of older individuals can live for a long time.  Many of these organisms have very long lifespans.  This would appear to contradict the evolutionary theory of aging because most individuals die when young but lifespan is long.  How can you explain this apparent contradiction. Group of answer choices -older, larger individuals have most of the offspring -all type III organisms have very slow metabolisms -type III organisms are trying to prove evolution wrong -type III organisms die at a constant rate

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?
