Areas of endemism of two biogeographic provinces in central Mexico based on their endemic Asteraceae: a conservation proposal

open access: yesRevista Mexicana de Biodiversidad, 2021
The Transmexican Volcanic Belt (TVB) and the Balsas Basin (BB), situated in central Mexico, stand out for their species richness and endemism. Documenting patterns of distribution of endemism is relevant, since species restricted to an area may become ...

Delimiting areas of endemism through kernel interpolation. [PDF]

open access: yesPLoS ONE, 2015
We propose a new approach for identification of areas of endemism, the Geographical Interpolation of Endemism (GIE), based on kernel spatial interpolation. This method differs from others in being independent of grid cells.

Biogeographic analysis of the American genus Echeandia (Agavoideae: Asparagaceae)

open access: yesRevista Mexicana de Biodiversidad, 2021
Echeandia (Asparagaceae) is an American genus of herbaceous geophytes. Its distribution is heterogeneous but concentrates along the Mexican Transition Zone (MTZ). We analyzed the species richness distribution and endemism of the group.

Species diversity, hotspot congruence, and conservation of North American damselflies (Odonata: Zygoptera)

open access: yesFrontiers in Ecology and Evolution, 2023
The rapid extinction of species is of considerable concern for biodiversity conservation. Identifying the drivers of species diversity and hotspots is beneficial for developing conservation strategies.

Distribution of freshwater fish from the Southern Neotropics reveals three new areas of endemism and show diffuse limits among freshwater ecoregions

open access: yesNeotropical Ichthyology, 2021
Ecoregions and areas of endemism are central concepts in biogeography. Based on collection records and the Endemic Analyses implemented with NDM/VNDM method we analyzed fish areas of endemism in the junction of three freshwater ecoregions related to the ...

Madagascar's grasses and grasslands:anthropogenic or natural? [PDF]

open access: yes, 2016
Grasses, by their high productivity even under very low pCO2, their ability to survive repeated burning and to tolerate long dry seasons, have transformed the terrestrial biomes in the Neogene and Quaternary.

Terrestrial molluscs of Pemba Island, Zanzibar, Tanzania, and its status as an "oceanic" island [PDF]

open access: yes, 2010
Pemba is thought to have had a longer and/or stronger history of isolation than its better-known counterpart, Unguja. The extent to which the biota support this hypothesis of greater oceanicity have been debated.

Spatial patterns of phylogenetic diversity and endemism in the Western Ghats, India: A case study using ancient predatory arthropods

open access: yesEcology and Evolution, 2021
The Western Ghats (WG) mountain chain in peninsular India is a global biodiversity hotspot, one in which patterns of phylogenetic diversity and endemism remain to be documented across taxa. We used a well‐characterized community of ancient soil predatory

Mammal endemism In Italy: A review [PDF]

open access: yes, 2018
Although there are various checklists of Italian mammals, there is not yet a synthesis of those mammals that are endemic to Italy. Therefore, we provide for the first time a detailed review on Italian mammal endemic species including endemic taxa ...

Patterns of Endemism in Turkey, the Meeting Point of Three Global Biodiversity Hotspots, Based on Three Diverse Families of Vascular Plants

open access: yesFrontiers in Ecology and Evolution, 2019
Centers of endemism and areas of endemism are important biogeographic concepts with high relevance for conservation and evolutionary biology. Turkey is located at the intersection of three global biodiversity hotspots (Mediterranean, Caucasian, Irano ...
