Brown thrashers are common birds that inhabit much of the United States. They use twigs, dry leaves, grasses, and similar materials to build their nests very low in trees or in shrubs. A nest typically contains two to six eggs per male-and-female breeding pair. Adult brown thrashers are preyed on by hawks and owls, while snakes frequently eat their eggs and offspring. The table shows reproduction data for four breeding pairs of brown thrashers in the summer of 2017.

King penguins are flightless aquatic birds found primarily in the Southern hemisphere. They live as a large colony and have highly social interactions. King penguins begin reproducing at six years of age and lay one or two eggs per reproductive cycle.Males and females share the incubation duties and raise the chicks together for about 15 months. When the young penguins get older, they form a large group guarded by only a few adult penguins, allowing the parents to forage for food without having to worry about their young. As a population, penguins could be classified as Select one: a. r-selected because only a few adult penguins care for the young penguins b. K-selected because they only lay one or two eggs per reproductive cycle c. K-selected because they live in a large colony, often sharing responsibility for caring for the young penguins d. r-selected because of the relatively long breeding cycle
In an iteroparous species lifetime fitness is maximized at investment, while in semelparous species level of reproductive an intermediate maximal effort is exerted in a single reproductive event Maximal an intermediate effort is exerted in one of many reproductive events an intermediate minimal effort is exerted in a single reproductive event maximal an intermediate effort is exerted in a single reproductive event an intermediate maximal effort is exerted in one of many reproductive events
Most species produce more offspring than can survive in the environment due to limited resources. O True O False
In one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.
What is often true of a population of organisms with a type Il suvivorship curve? they produce few offspirng and invest more energy in each offspring they produce more offspring and invest little energy in each they have low death rates during early life stages they are equally likely to die at any age
Mockingbirds typically lay 3 eggs. If the mockingbird produces more than three eggs their young are often malnourished because they have so many to feed. If less than 3 eggs are produced they may not have any viable offspring. This is an example of
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.
Many factors influence a species mode of reproduction. Use the descriptions of the following species to predict what system of hermaphroditism they probably display. 1. Individuals rarely disperse once they are sexually mature, and the largest males get the most matings. Females protect the eggs. [Select] 2. Resources are of uniform quality and evenly dispersed, so males are unable to monopolize them. Females are larger than males; Males protect the eggs. [Select] 3. Individuals are solitary, rarely meet others, and have no way of knowing the sex ratio in the population. There is no parental care.

Polygyny is a common mating system in nature. Which one of the following scenarios is LEAST likely to result in a polygynous mating system? Male stalk-eyed flies form leks where receptive females come visit Male Neotropical giant damselfly defend water-filled tree holes, which are the oviposition sites for females. Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites. Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime. In the bumblebee-wolf Philanthus bicinctus, females are unreceptive until they finish constructing the long underground burrow as nest sites. Males search for locations containing a number of newly constructed burrows and attempt to control these sites against the intruders. Your cousin Peter…
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
Adult Lake Trout and Chinook salmon live in deep, open water and eat small prey fish, but they have very different reproductive strategies. Lake Trout live up to 10 years and spawn (breed) every year near the lake shore. Most Lake Trout that live to adulthood eventually die in the open water and their carcass settles to the lake bottom. Salmon live 3-4 years and only spawn once. When they spawn, they swim up river in the Fall (sometimes all the way to MSU, via the Red Cedar River), where they build nests in gravelly river beds, lay their eggs in the nests and the males fertilize the eggs. Then, both the males and the females die. Q3. In 1-2 sentences, explain how the life history trade-offs of Chinook salmon and Lake Trout are different. How do such different strategies still increase fitness of the individuals?
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…
