Biogeography 1
From Chapter 1 of "Biogeography" by Lomolino et al. (5th ed.)
Term | Definition |
---|---|
biogeography | The science that attempts to document and understand spatial patterns of biological diversity; modern techniques integrate multiple disciplines |
biotas | Assemblages of plants, animals, and microbes--separately |
historical biogeography | A subdiscipline that attempts to reconstruct the origin, dispersal, and extinction of taxa and biotas. |
ecological biogeography | A subdiscipline that attempts to account for present distributions and geographic variation in diversity in terms of interactions between organisms and their physical and biotic environments. |
paleoecology | One traditional means of bridging the gab between the two subdisciplines by investigating the relationships between organisms and past environments, and using data on both the biotic composition of communities and abiotic conditions. |
phylogeography | The scientific analysis of the evolutionary interrelationships of populations of species and of closely related life-forms based on their gene sequences in relation to geographic space. |
pattern | The nonrandom, repetitive variation of focal elements among units or along relevant gradients. |
scientific crises | When the long-standing accepted explanation seems so fraught with exceptions and inconsistencies that it no longer serves to guide scientific inquiry and discovery. |
uniformitarianism | The assumption that the basic physical and biological processes operating on Earth today have operated throughout time and are manifestations of universal scientific laws. |
actualism | The processes and forces driving speciation, dispersal, and extinction operated in the past by the same mechanisms that they do today, although varying in their rates and relative importance. |
consilience | The principle that information from unrelated sources or fields, when intersected, provides greater scientific rigor and stronger conclusions. |
conservation biogeography | A newly articulated discipline that applies lessons from biogeographic theory and patterns to conserve biological diversity, and which emphasizes the need to conserve the geographic, ecological, and evolutionary context of nature. |
