Population Ecology
This type of population growth occurs when resources are abundant and predators are few.
What is exponential growth?
A wetland filtering pollutants from water is an example of this type of ecosystem service.
What is a regulating service?
Local extinction of a species from a specific area is called this.
What is extirpation?
What is the hard structures in fish that can be used to estimate age?
What are otoliths?
Birds are considered the ultimate flying machines partly because of their lightweight but rigid ________.
What is a skeleton?
The four mechanisms of population change
What is birth, death, immigration, and emmigration?
When you can consume, collect, or take a resource provided by the environment, it is considered this type of ecosystem service.
What is a provisioning services?

What are cultural services?
This type of ecology focused on supporting biodiversity in human-dominated landscapes.

More than 60% of these mammals are threatened or declining worldwide.
What are large carnivores?
What is the maximum population size an environment can sustainably support?
What is carrying capacity?
The processes, habitats and biodiversity that produces all other types of services is defined as this type of ecosystem service.
What is a supporting service?
Scientists use these two tools to monitor many terrestrial animal populations.
What are radio collars?
This is the process where deep, nutrient-rich water rises to the ocean surface.
What is coastal upwelling?
This disease causes bats to wake repeatedly during hibernation, rapidly depleting their fat reserves and often leading to starvation.
What is white-nose syndrome?
Species with low reproductive rates and narrow niche breadth are especially vulnerable to this human activity.
What is human exploitation (overharvesting)?
These are the three methods that a scientist could use to measure ecosystem services.
What are field studies, national censuses, and models?
Predators scare prey into changing behavior, creating ecosystem-wide effects.
What is a behaviorally mediated trophic cascade?
This fish-sampling technique is commonly used on shallow beaches in the California Delta.
What is beach seine (seining)?
When top predators disappear and medium-sized predators increase, this phenomenon occurs.
