| Williams et al. compare the biogeographic signal in mitochondrial and nuclear DNA sequences in Indo-West Pacific starfish and snapping shrimp. |
|
| Are the biogeographic and ecological responses of tropical-rain forest species representative of those of other fragmented biomes? |
|
| The biogeographic patterns of vicariance and range expansion may also provide insight to the mechanics of this extinction event. |
|
| Alternatively, true differences may exist in the degree to which species hybridize in different biogeographic regions. |
|
| Russell reminds readers that we do not know the biogeographic origin of birds, or theropods, or dinosaurs. |
|
| This ancestral biogeographic distribution encompassed a much broader range, comprising Siberia and southern Europe-northern Africa. |
|
| This section is highlighted by excellent summaries of the major biogeographic realms and their endemic faunas. |
|
| The association between environmental changes and biogeographic and macroevolutionary changes is potentially an important area of paleontological research. |
|
| The diagnosis of Glades through synapomorphy becomes the starting point for the investigation of functional, temporal, adaptive and biogeographic questions. |
|
| Second, the results of standard cladistic biogeographic analyses, which may combine groups of different ages, cannot be unambiguously attributed to any particular cause. |
|
| But because they do not advocate this practice, they review island biogeography and biogeographic principles of reserve design in separate, widely spaced chapters. |
|
| First, as noted, there is a biogeographic separation of Upper and Lower Guinea by the dry zone known as the Dahomey Gap. |
|
| As a result, existing biogeographic algorithms are still essentially based on racial definitions, and have proved fairly vague. |
|
| It will most likely arise where a site has been designated using only one such Criterion and for only one species or biogeographic population. |
|
| Ice Ages Global patterns of continental icesheet expansion and recession, isostasy, sea-level changes, and associated biogeographic records. |
|
| Differences in abiotic factors such as differential effects of glaciation and sea-level changes on land and in the sea may also greatly influence biogeographic patterns. |
|
| Studies in karyology, molecular genetics, and biogeographic patterns have also assisted in understanding their phylogeny and diversification. |
|
| An alternative method of determining biogeographic regions involves calculating degrees of similarity between geographic regions. |
|
| Three biogeographic theories are briefly described, which are generally inspirational, especially for the geobotanical approach. |
|
|
|
| Also, the distribution and extent of plant species and genetic variation are related to factors such as taxonomic status, life history and biogeographic history. |
|
| They also have important biogeographic implications, given that lunulate sand dollars are today rather rare in the regions in which monophorasterids were once common. |
|
| In summary, without additional substantial support from the IOC, the momentum generated and added value of the ocean biogeographic data system will be lost. |
|
| Its main biogeographic units are the Northern Adriatic, the Central Adriatic, and the Southern Adriatic. |
|
| To have included in the Ramsar List those wetlands which are believed to be of importance for maintaining the biological diversity within each biogeographic region. |
|
| When selecting a biogeographic regionalisation scheme to apply, it is generally most appropriate to use a continental, regional, or supranational scheme rather than a national or subnational one. |
|
| The area is considered of biogeographic interest because it lies in the transition between East and West African vegetation zones and has evidence of a Pleistocene refugium. |
|
| Genic variation, systematic, and biogeographic relationships of some galliform birds. |
|
| The Ituri forest is valuable because of its biogeographic history as a Pleistocene refugia with endemic plant communities found in rocky outcrops, or inselbergs, in the Reserve. |
|
| Of what use are biogeographic classifications? |
|
| The investigators noted several biogeographic trends. |
|
| It is thought that the present-day distribution patterns of plant and animal forms, as reflected in such biogeographic regions, are the result of many historical and current causes. |
|
| One of the objectives of the MAB Programme is to create a representative list of sites corresponding to the biogeographic provinces of the world but this is not the objective of the World Heritage Convention. |
|
| For each population listed under Criterion 9 the name of the biogeographic population, as well as the number of individuals of this population regularly occurring in the site, should be listed. |
|
| The meeting is expected to discuss and provide indication on whether, with a view to further negotiations, this scope should be limited on the basis of biogeographic or other considerations. |
|
| In applying Criterion 1 to mangrove swamps, special attention should be given to the listing of areas which are in pristine condition or have biogeographic or scientific importance and protection needs. |
|
| Properties should contain habitats for maintaining the most diverse fauna and flora characteristic of the biogeographic province and ecosystems under consideration. |
|
| Distribution and biogeographic history highly determine the origin of migration in birds of prey. |
|
| The purpose of this article is to present a tentative procedure for quantifying forest protection goals, and to identify the most important gaps in forest protection at the scale of biogeographic regions in Sweden. |
|
| Alternatively, when a relatively homogenous smaller area is in consideration, it should be representative of other such areas within that biogeographic region, should they exist. |
|

|
| Eocene echinoids, the Suwannee Strait, and biogeographic taphonomy. |
