Biogeography Evidence

Biogeography refers to the study of the geographic distribution of species and ecosystems, examining how historical, environmental, and ecological factors influence the presence and abundance of organisms in different regions. Species distribution evidence encompasses patterns and data that illustrate how species are spread across various habitats and geographical areas, often reflecting evolutionary history and ecological interactions.

Overview

Biogeography is a vital field that examines how species are distributed across the planet and the factors that influence this distribution. It combines elements of ecology, geology, and evolutionary biology to understand the complex interactions between organisms and their environments. By studying ...

Key Terms

Biogeography
The study of the distribution of species and ecosystems in geographic space and through geological time.

Example: Biogeography helps explain why certain species are found in specific regions.

Endemic Species
Species that are native to and found only within a specific geographic area.

Example: The lemurs of Madagascar are endemic to that island.

Invasive Species
Non-native species that spread widely in a new habitat, often causing harm to native species.

Example: The zebra mussel is an invasive species in North America.

Habitat Fragmentation
The process by which large habitats are broken into smaller, isolated patches.

Example: Urban development often leads to habitat fragmentation.

Biodiversity Hotspot
A biogeographic region with significant levels of biodiversity that is under threat from human activities.

Example: The Amazon rainforest is considered a biodiversity hotspot.

Continental Drift
The movement of the Earth's continents relative to each other.

Example: Continental drift explains the distribution of similar species on different continents.
