WHAT IF? Given the latitudinal differences in sunlight intensity (see Figure 52.3), how might you expect the carrying capacity of plant species found at the equator to compare with that of plant species found at high latitudes?

Short Answer

Expert verified

The carrying capacity of plant species found at the equator would be larger than that of those found at high latitudes since direct sunlight falls on the equator.

Step by step solution

01

Carrying capacity of plant species.

Carrying capacity is defined as the average population size of a species that an environment can support.Below the carrying capacity, the number of individuals may shoot up,and above which the number may decline due to limited resources.

The carrying capacity can vary for each species in a habitat, and several environmental factors restrictthe population size of species.

02

Latitudinal variation

The Earth鈥檚 curved surface causes a latitudinal difference in the intensity of sunshine,as light energy strikes the tropics directly between 23.5 degrees north and 23.5 degrees south.

In this region, more light and heat per unit of the surface area is available.

03

Plant species have large carrying capacity at the equator

At the equator, the carrying capacity of plant species is larger because more sunlight is available,and the ecosystem can provide better conditions to reproduce and survive. The ecosystem will support the largest population in the equator.

Imagine that you are constructing a life table like Table 53.1 for a different population of Belding鈥檚 ground squirrels. If 485 individuals are alive at the start of year 0鈥�1 and 218 are still alive at the start of year 1鈥�2, what is the proportion alive at the start of each of these years (see column 3 in Table 53.1)?

In the fish called the peacock wrasse (Symphodus tinca), females disperse some of their eggs widely and lay other eggs in a nest. Only the latter receive parental care. Explain the trade-offs in reproduction that this behavior illustrates.

Mice that experience stress such as a food shortage will sometimes abandon their young. Explain how this behavior might have evolved in the context of reproductive trade-offs and life history.

What do the data represented in the graph suggest about the effects of cane toads on the predatory behavior of red-bellied black snakes in areas where the toads are and are not currently found?

To estimate which age cohort in a population of females produces the most female offspring, you need information about the number of offspring produced per capita within that cohort and the number of individuals alive in the cohort. Make this estimate for Belding鈥檚 ground squirrels by multiplying the number of females alive at the start of the year (column 2 in Table 53.1) by the average number of female offspring produced per female (column 5 in Table 53.1). Draw a bar graph with female age in years on the x-axis (0鈥�1, 1鈥�2, and so on) and total number of female offspring produced for each age cohort on the y-axis. Which cohort of female Belding鈥檚 ground squirrels produces the most female young?
