Population Dynamics

Click on the flashcard to see the answer

What is population dynamics?

Population dynamics is the study of how populations of organisms change over time and space.

What factors influence population dynamics?

Factors include birth rates, death rates, immigration, emigration, and carrying capacity.

How does carrying capacity affect population dynamics?

Carrying capacity limits the maximum number of individuals an environment can support.

What is the logistic growth model in population dynamics?

The logistic growth model describes how a population grows rapidly initially but slows as it approaches carrying capacity.

What is meant by the term 'population density'?

Population density refers to the number of individuals living in a unit area or volume.

How do immigration and emigration affect population numbers?

Immigration adds to a population, while emigration reduces its size.

What is exponential growth in population dynamics?

Exponential growth occurs when the population size increases at a constant rate per unit time.

What role do predators play in population dynamics?

Predators can regulate prey populations, potentially preventing them from exceeding the carrying capacity.

What is demographic transition?

Demographic transition is the transition from high birth and death rates to lower birth and death rates in a population.

How do natural disasters impact population dynamics?

Natural disasters can drastically reduce population size and alter population dynamics.

What is a population bottleneck?

A population bottleneck is an event where a population's size is significantly reduced, affecting genetic diversity.

How can human activities affect population dynamics?

Humans impact population dynamics through habitat destruction, pollution, and resource depletion.

What is age structure in population dynamics?

Age structure refers to the distribution of individuals in a population across different age groups.

Why is genetic diversity important in populations?

Genetic diversity increases resilience to environmental changes and disease.

How does competition influence population dynamics?

Competition for resources can limit population growth and lead to natural selection.
