When assessing the consequences of an interaction on both partners these can be classified as beneficial or negative to their fitness. Beneficial aspects included all benefits received from the interaction and negative aspects include the________.

Competition is often symmetrical, where both interacting species exploit resources equally and at the same rate until coexistance is achieved

Two competing species can reach greater population densities when both exploit resources at equal rates, and the population density of one species will decrease as the rate of resource exploitation of its competitor increases

In the differential equation dP/dt=baNP-mP, where b=rate of prey conversion to predator offspring, a=predator capture efficiency, N=total number of prey, P total number of predators, and m=predator mortality, can be interpreted as

An adequate written interpretation of dN/dt = B-D would be:

The maximum number of individuals that can be supported at a given ecosystem and is represented by the letter K is referred to as

The differential equation represented as dN/dt=rN(1-N/K) is generally used to model and describe the _______ growth of a populations

If you are studying the distribution of willows (Salix sp.) across Central Texas and compare it to the distribution of creosote bush (Larrea tridentata) in West Texas, you can infer that the association of willows with the water sources such as ponds or rivers often results in a _______ distribution. On the other hand the Chihuahuan dessert habitat of the Creosote bush gives them a ______ distribution.

If a scientist is conducting a long term study on Polar bears, and documents their presence during the Spring, when he or she reports the number of individuals in a populations he is documenting the ________

Populations of marsupials are found in the Americas and Australia, however in terms of diversity the Americas has a lot less species than Australia. The fact that populations of marsupial are found along the Americas and Australia can be best explained by

A group of organisms that share very similar alleles, a very common ancestry and occupy the same geographic area during the same time periods, is generally referred to as

Which of the following is not a phase stage during population logistic growth

Besides births and deaths, a population open to gene flow will experience changes in population size based on the number of ______ and _______ individuals

An adequate written interpretation of dN/dt = B-D would be:

All of the following could be considered examples of evidence for descent with modification EXCEPT

Fluctuations in population size as a result of environmental change can drive small populations extinct

Organisms that are capable of two or more separate periods of reproduction are referred to as

An organism that is capable of produce eggs at one time and sperm at a different time during their life history is known as

A population with ___ selection reproductive strategy is characterized by high population growth rates, whereas a population with ___ selection reproductive strategy is characterized by slower population growth rates

Neutral theory of evolution suggests that changes in the genotype allele frequency that are not passed to the next generation as a result of reproductive success or adaptive selection are considered neutral

All of the following are strategic decisions that most animals in populations need to make during their life history, except

An organism that is capable of two or more separate periods of reproduction is referred to as

During lecture we talked about two types of drought tolerant species, the Creosote bush and the Saguaro cactus. The Creosote bush is widely distributed across the South West, however the Saguaro Cactus distribution is limited to the Sonora desert in South Arizona. The drastic differences in distribution between these two species can be explained by

Which of the following species has a type II survivorship curve

Complex life cycles allow life histories the flexibility to respond to differences in selection pressures on different cycle stages
