Information about a species' death rate at different ages can be summarized by a survivorship curve. The horizontal axis represents different ages in the life of an individual of that species. The vertical axis indicates the number of offspring that survive a specific age to make it to the next age. Taken together, the curve shows how many individuals of different ages remain alive over time. Age The adjacent survivorship curve represents a curve for an unknown species. Which of the following statements correctly describes the characteristics of a species that might produce this curve? This species has few offspring at a time and thus is able to put a lot of effort into raising them. The offspring have a high survival rate, and the highest death rates are in older adults. This species has a steady rate of survival versus death. Offspring are not more likely or less likely to die than adults are. In other words, roughly the same number of individuals die at every age in the species. This species has many offspring at a time and does not put in much, if any, parental effort. Many of the offspring die early, and few survive to older ages. Number of survivors (logarithmic scale)

Suppose that researchers wanted to examine the combined effects of an introduced predator (a trout) and the trematode parasite Ribeiroia on amphibian populations. To do this, they established frog populations in each of 40 artificial ponds. Each pond was assigned at random to one of four treatments (10 ponds per treatment): 1) neither trout or parasites were added to the pond (the "No trout, no parasite" treatment); 2) no trout were added but parasites were added ("No trout, parasite added"); 3) trout were added but parasites were not added ("Trout added, no parasite"); and 4) both trout and parasites were added ("Trout added, parasite added"). Each pond contained refugia where tadpoles could avoid attack by trout, to avoid fish predators driving frog populations to extinction in an artificial pond, unlike what typically occurs in a natural pond. After two breeding seasons, the researchers estimated the density of frogs in each pond. The results are shown in the table and the figure.…

For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. 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. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.

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?

Very few species on Earth are completely r-selected or K-selected. Many species in their natural habitats demonstrate a life strategy that ranges along a continuum between r- and K-selected strategies. Use this information to answer the 3 sub-parts. a) Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup.Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only 25% of the pups survive past the first year. Sea otter fur was highly sought after between the 18th century and the early 20th century. Through conservation efforts, the number of sea otters increased. The current world population is estimated to be between 1 000 and 2 000 individuals, and they are considered to be endangered. Their main food source is sea urchins, molluscs, and crustaceans. Sea…

You are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators Design an experiment to test the hypothesis that this turtle…
Is the species a generalist or a specialist and how does this niche impact the species of the wild. The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common.
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: _________
