Historical and Ecological Biogeography

Study Notes

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.

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.
