Population Ecology - APES

Front

What is Emigration?

Back

Emigration is the process of individuals moving out of a population, leading to a decrease in population size.

Front

What does Exponential Growth mean in population ecology?

Back

Exponential growth refers to a population increasing rapidly in size when resources are abundant, often depicted as a J-shaped curve on a graph.

Front

Define 'Threatened Species'.

Back

Threatened species are those that are likely to become endangered in the near future due to various factors affecting their survival.

Front

What is Habitat Fragmentation?

Back

Habitat fragmentation is the process where large habitats are broken into smaller, isolated patches, often due to human activities, which can threaten biodiversity.

Front

What is Intraspecific Competition?

Back

Intraspecific competition occurs when individuals of the same species compete for limited resources, such as food or territory.

Front

What is Immigration?

Back

Immigration is the movement of individuals into a population, which can lead to an increase in population size.

Front

What are Limiting Factors?

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of a population.

Front

What is Logistic Growth?

Back

Logistic growth describes a population's growth that slows as it approaches the carrying capacity of its environment, often depicted as an S-shaped curve.

Front

What is Overexploitation?

Back

Overexploitation refers to the unsustainable use of natural resources, leading to a decline in species populations.

Front

What are Invasive Species?

Back

Invasive species are non-native organisms that spread widely in a new habitat, often causing harm to native species and ecosystems.
