Population density declines with decreasing organism
size.

A group of interbreeding organisms that represents the level of organization at which speciation begins

Insects that are abundant in tropical and subtropical
environments, where they gather nectar and pollen from
a wide variety of flowers

One in which individuals within a population have an equal chance of living anywhere within an area.

What is this fish that can be found in streams across most of the east central United States and was abundant enough that early ichthyologists cited it as one of the most common and most valuable food fishes in the region?

Environment limits the geographic distribution of species

The average number of individuals or units per space

What is the statistical study of populations and how it changes overtime?

What is the actual niche of a species whose distribution is limited by biotic interactions such as competition, predation, disease, and parasitism?

Consists of the adaptations of an organism that influence aspects of its biology, such as the number of offspring it produces, its survival, and its size and age at reproductive maturity.

On small scales, individuals within populations are
distributed in patterns that may be random, irregular, or
clumped.

What continent do large scale of kangaroo species dwell?

What kind of population are likely to have greater variability and thus more potential to adapt to changes

A type of small scale distribution where one in which individuals are uniformly spaced

The ability to produce an abundance of offspring or new growth

On large scales, individuals within a population are
random.

Give 1 of the 3 basic patterns of distribution that are observed on small scales

The degree to which a living organism is suited to a particular environment.

What is the physical conditions under which a species might live, in the absence of interactions with other species?

A phenomenon where plants secrete toxins to excrete to inhibit growth of nearby individuals

Rare species are more vulnerable to extinction than those who are common species

What is the chemical substances secreted by some animals for communication with other members of their species.

The proportion of a particular allele of a gene in the gene pool of the population.

The individuals have a much higher probability
of being found in some areas than in others

Sub-filled of ecology that deals with the dynamics of species population and how these populations interact with the environment.
