After observing a finite population of asexually reproducing salamanders, which of the following outcomes is consistent with Müller’s ratchet? a. The population fitness will decline due to the least fit individuals randomly not surviving to produce offspring into the next generation. b. The population fitness will increase due to the most fit individuals randomly not surviving to produce offspring into the next generation. c. The population fitness will decline due to the most fit individuals randomly not surviving to produce offspring into the next generation. d. The population fitness will increase due to the least fit individuals randomly not surviving to produce offspring into the next generation.
Two human populations have the same net reproductive rates (R0), but different generationtimes. In what ways are these two populations similar and different?
Which of the following is associated with the reproductive potential of a species? a. few offspring b. many offspring c. semelparity d. fecundity
Females of a lizard species each produced, on average, about 15 eggs during one breeding season, and about the same number of eggs during each of the next four breeding seasons. This suggests that Group of answer choices the cost of reproduction is relatively high for these females the idea of trade-offs does not apply to this species the cost of reproduction is relatively low for these females this species is semelparous there must be high mortality among females in this species
Pest populations are heterogeneous and therexchange of genes between local populations" True Or False
Is the following case study an r-strategist or a K-strategist? American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Offspring are left to develop, hatch, and grow on their own, maturing in about three months.
Is the following case study an r-strategists or a K-strategists? Andean condors reach sexual maturity at five to six years. Reproduction is slow; females lay only one or two eggs every other year. Offspring are cared for by both parents for at least one year. Andean condors are long-lived and can survive for seventy to seventy-five years.
In populations subjected to high levels of predation a. individuals should invest little in reproduction so as to maximize their survival. b. individuals should produce few offspring and invest little in any of them. c. individuals should invest greatly in reproduction because their chance of surviving to another breeding season is low. d. individuals should stop reproducing altogether.
In a habitat there are 7,500 individuals of P. rufipes, 40% of which have long and thin ovipositors and 60% have short and thick ovipositors. During a single year 250 wasps with long and thin ovipositors died while 325 were born. In that same year, 650 wasps with short, thick ovipositors were born and 800 died. Calculate the per capita growth rate (r) of the two subpopulations of P. rufipes. Per capita growth rate of P. rufipes with long and thin ovipositors: _________ Per capita growth rate of P. rufipes with short and thin ovipositors: _________
Thornhill’sresearch on mate selection among scorpionflies (Panorpa latipennis) indicatesthat male ____________ translates into successful mating opportunities.a.body sizeb.aggressivenessc.nuptial offeringd.both body size and aggressivenesse.both body size, aggressiveness, and nuptial offering
The second assumption in formulating Lack's (1947) hypothesis is that clutch size affects only offspring survival. The data that are presented in the figure were obtained in an experiment conducted by Schluter and Gustafsson in 1993 to test this assumption. The researchers removed or added eggs to nests and monitored the offspring that hatched from the nests, recording subsequently the reproductive output for offspring females after they had matured. i. Females reared in nests from which eggs had been removed produced larger clutches. ii. Females reared in nests into which eggs had been added produced smaller clutches. iii. Observations described in statements i and ii are consistent with the second assumption. iv. Observations described in statements i and ii reveal a trade-off between offspring quantity and quality. Question 3 options: A) All statements convey accurate information. B) Statements i and ii convey…
