Endemic taxa are those restricted to a specific area, and could bedefined as the exclusive biodiversity of a region. An area of endemismcontains taxa found nowhere else and could be catalogued as irreplaceable and of highpriority for conservation. proposed the parsimony analysis of endemicity (PAE) as a tool to detect areas ofendemism. PAE, a method of historical biogeography, is analogous to cladisticmethods used in phylogenetics analysis, and unites areas (taxa in cladistics)based on their… 

Biogeography of Chilean herpetofauna: distributional patterns of species richness and endemism

The richness and endemism patterns registered for Chilean herpetological taxa may be explained by an historical mechanism, in accordance with previous biogeographical proposals, and inclusion of new protected areas at the regional level for the Mediterranean region of south-central Chile and for local northern and southern quadrats with high species richness andEndemism is suggested.

Areas of endemism in the Brazilian Atlantic Forest based on the distribution of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae)

The results of the analysis of endemicity on the distributional patterns of 198 species and subspecies of dung beetles allowed the definition of three generalized areas of endemism: Southeast, Central and Southwest, allowing us to argue that processes forming these regions have influenced dung beetle species as described for other groups of organisms.

Exploring the different facets of plant endemism in the South-Eastern Carpathians: a manifold approach for the determination of biotic elements, centres and areas of endemism

The spatial structure of plant endemism in its South-Eastern subunit is explained by the complementary use of diversity indices, parsimony analysis of endemicity (PAE), biotic element analysis (BEA), and barrier analysis.

Areas of endemism of small mammals are underprotected in the Atlantic Forest

Atlantic Forest (AF) is amongst the most threatened forests in the world. To decide where conservation efforts should be focused to preserve species, assessment of ecological and biogeographic

Application of parsimony analysis of endemicity to mexican gymnosperm distributions : grid-cells, biogeographical provinces and track analysis

The distribution patterns of gymnosperms agree with the existence of several Mexican biogeographical provinces, and a different historical biogeography of the Mexican peninsulas from the rest of the country is evident.

Biogeographical patterns of the avifaunas of the Caribbean Basin Islands: a parsimony perspective

We analyzed the avifaunas of the Caribbean islands and nearby continental areas and their relationships using Parsimony Analysis of Endemicity (PAE), in order to assess biogeographical patterns and

Prioritizing areas for conservation of Mexican carnivores considering natural protected areas and human population density

In México, 63% of the mammalian carnivore species are considered threatened. Therefore, we performed a prioritization exercise to find sets of areas needed for the conservation of Mexican terrestrial

Patterns of plant endemism in the Romanian carpathians (South-Eastern Carpathians).

The study of endemism, both a biogeographical and evolutionary phenomenon, can reveal valuable historical and ecological aspects of a region's flora. Nevertheless, due to taxonomic inconsistencies



Application of parsimony analysis of endemicity in Amazonian biogeography: an example with primates

It is suggested that PAE can be used as a tool to objectively identify areas of endemism at an intra-continental scale as well as to make historical inferences and the value of a PAE cladogram should be always evaluated by congruence with area cladograms built upon cladistic biogeography procedures.

Setting Conservation Priorities: The Importance of Endemism and Phylogeny in the Southern African Orchid Genus Herschelia

The southern and south-central African terrestrial orchid genus Herschelia contains several rare and endangered species. The distribution patterns of the species were assessed and classified into the

Species Richness, Endemism, and the Choice of Areas for Conservation

It is found that the use of Carnivora as an umbrella taxon is an unreliable method for invertebrate conservation and richness and endemism patterns were not generally similar between taxa.

Taxonomic, edaphic and biological aspects of narrow plant endemism on marched sites in mediterranean South Africa and Australia

The strong overall similarities in patterns of endemism on the two continents suggests similar speciation histories in phylogenetically distantly related Boras.

Rare species, the coincidence of diversity hotspots and conservation strategies

SPECIES conservation in situ requires networks of protected areas selected for high conservation interest1–3. Throughout most of the world, however, there are neither the resources nor the time to

HISTORICAL BIOGEOGRAPHY: Introduction to Methods

The various methods of biogeography think some of them can be integrated in a single biogeographic approach, with the capability of resolving different problems, such as the recognition of spatial problems.

The biodiversity challenge: Expanded hot-spots analysis

By concentrating on these hot-spot areas where needs are greatest and where the pay-off from safeguard measures would be greatest, conservationists can engage in a more systematised response to the challenge of large scale impending extinctions.

Measuring biodiversity taxonomic relatedness for conservation priorities

Five new measures of taxonomic diversity are compared with existing measures of species richness and taxonomic root weighting for prioritising areas for the conservation of biodiversity and it is concluded that combining species richness with taxonomic Diversity to give a single measure inevitably involves compromise.
