Peppered moths were affected by pollution which led to an increase in dark colored moths and a decrease in the light colored moths. What type of selection is exhibited?

In many bird species, males are larger and flashier than females. This occurs because females select those males.

[blank_start]_____________[blank_end] occurs when a population size is severely reduced. When a small group of individuals move to a new area branching out from the original population this is called the [blank_start]___________________[blank_end]. When alleles move between populations you have [blank_start]_______________________[blank_end].

When genes cannot flow (reproduction cannot happen) between two populations because they have become so different this is called?

Types of Reproductive isolation: Timing of reproduction differs in [blank_start]___________[blank_end] isolation Size or shape of an individuals reproductive parts prevent it from mating in [blank_start]____________[blank_end] isolation Differences in behavior causes [blank_start]_______________[blank_end] isolation When gametes meet up but are unable to form a zygote [blank_start]_____________[blank_end] occurs. When individuals can produce offspring but those offspring cannot produce functional gametes [blank_start]_________________[blank_end] occurs

What is a population?

What type of population size estimation is shown in the picture?

Which picture represents random distribution?

Which image represents clumped distribution?

What is the per capita growth rate (r) of a shrew population if the birth rate is .4 and the death rate is .1?

What is the size of a shrew population after one month if the starting shrew population is 300 shrews and the per capita growth (r) is 0.3?

[blank_start]________________[blank_end] curves, death rate is high early in life. [blank_start]______________[blank_end] curves death rate for the population is fairly constant. [blank_start]___________[blank_end] curves; death occurs later in life.

When did the shrew population reach carrying capacity?

Which population has the highest percentage of births compared to the rest of their population?

In the United States are their more women or men above 60?

Density independent limiting factors include forest fires, tornadoes and floods.

Select the following reasons carrying capacity could be reached.

Species interactions: A bird nesting in a tree is an example of [blank_start]________________________[blank_end]. An insect pollinating a plant is an example of [blank_start]_________________[blank_end]. Roundworms living in a dog's intestines is an example of [blank_start]________________[blank_end]. Predation occuring between a lynx and hare is an example of [blank_start]_____________________[blank_end].

A non-poisonous ant is striped black and yellow to prevent from being eaten. This is an example of _______________.

When a barren habitat such as a new volcanic island begins to colonize these individuals arrive first?
