Individuals that belong to the same species and live in a given area at a particular time.

Pollution that runs off from diffuse areas (eg. agriculture)

Ecologists commonly use this type of conceptual model to illustrate the complex interactions among organisms within an ecosystem

This factor can influence air temp near streams

If the probability of an individual surviving is NOT influenced by population, we say the population growth is this

Areas in which dissolved oxygen is so low that little life can survive

An animal that consumes animals that consumes plants.

Non-targeted harvested species; often discarded or harmed

This maximum content of this water characteristic is influence directly by temperature, where colder waters can hold more.

The limit to the number of individuals in a population that can be supported by available resources in an ecosystem

When human waste enters a waterway, an INCREASE in this measure of oxygen will occur as a result of decomposition

The amount of solar energy captured by plants through photosynthesis

This strategy, based on logistic growth curves, is promoted as a way to produce the greatest amount of fish for harvest without reducing the number of fish available for the next year.

A man-made infrastructure through which a stream is suppose to flow under a road. In NH, these are often undersized and in need of replacement.

This type of population growth is characterized by initially rapid population growth followed by a deceleration in growth rate as it reaches carrying capacity. Commonly depicted with an "S-shaped" curve

Referred to as TMDLS for short, these are limits to the amount of a contaminant allowed to enter waterways to prevent degradation of aquatic systems

Nitrogen and this other macro nutrient are considered limiting factors to primary production in aquatic systems

A combination of abiotic and biotic conditions that characterize where a species is actually found

These three factors are used to calculate stream discharge in cubic meters per second.

An _____ selected species is likely to exhibit fast population growth with short generation time.

Process by which a body of water experiences an increase in primary productivity due to an increase in nutrients from human sources

The range of abiotic conditions in which a species can persist

Actual set of physical traits expressed by an individual

Surface waters in New England have been negatively impacted by this; it was the result of air pollution generated in the mid-west decades ago.
