Historical and Ecological Biogeography

Historical Biogeography

• Examines the geographical distribution of species over long periods of time, tracing their evolutionary history and migration patterns.
• Focuses on the historical processes that have shaped current biodiversity patterns, including continental drift, climate change, and mass extinctions.
• Utilizes phylogenetic analyses, fossil records, and paleoclimate data to reconstruct past distributions and understand the evolutionary relationships among species.
• Aims to understand the origins and diversification of species within their geographic ranges.
• Involves identifying and tracing historical biogeographic events, such as vicariance (the splitting of a species' range due to geographic barriers) and dispersal (the movement of species across a geographic area).
• Studies the impact of past events on present-day species assemblages and the distribution of related species.

Ecological Biogeography

• Focuses on the interactions between species and their environment that influence current biodiversity patterns.
• Investigates factors like habitat suitability, resource availability, competition, predation, and disturbance regimes to explain species distributions within a geographic area.
• Explores the ecological mechanisms maintaining and changing species diversity across different habitats or ecosystems.
• Examines how species respond to environmental gradients and the factors that determine their abundance and coexistence.
• Emphasizes the influence of ecological processes such as competition, predation, and resource partitioning on species distributions and diversity.
• Considers the effects of abiotic factors like temperature, precipitation, and soil types on biodiversity.
• Studies how species interactions and environmental conditions influence the distribution of communities and ecosystems.
• Analyses how species richness and diversity vary across environmental gradients.
