Ecology and Population Dynamics

These flashcards cover key vocabulary terms and concepts related to ecology and population dynamics as discussed in the lecture.

Ecology

The study of interactions between organisms and their environment.

Population

A group of individuals of one species that use a common area and resources.

Mark-recapture method

A technique used to estimate population size for mobile species by capturing, marking, and releasing individuals.

Carrying capacity (K)

The maximum population size of a certain species that a given habitat can support.

Exponential growth

Population growth that occurs when resources are plentiful and is not limited by population density.

Logistic growth

Population growth that slows as the population approaches carrying capacity, affected by density-dependent factors.

Life history

The schedule of fundamental events in the life of an organism, including growth, reproduction, and survival.

Density-dependent factors

Factors that affect population growth based on population density, such as resource availability.

Density-independent factors

Factors whose effects on the size or growth of a population are not related to the density of the population.

Population dynamics

The study of how populations change over time, including factors that influence growth and decline.

What is transpiration?

Transpiration is the process by which moisture is carried from plants to the atmosphere, primarily through small openings in leaves called stomata.

What is condensation?

Condensation is the conversion of water vapor to liquid water, occurring when the air cools and cannot hold all its water vapor.

What is precipitation?

Precipitation refers to any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

What is collection in the water cycle?

Collection is the stage in the water cycle where precipitation gathers in bodies of water like rivers, lakes, and oceans.

What factors affect the water cycle?

Factors that affect the water cycle include temperature, wind patterns, humidity, and geographical features.
