“…The EA analysis based on the optimality criterion was performed in NDM/VNDM v3.1 (Goloboff, 2016), using geographical coordinates of 324 species converted by GeX (Szumik et al, 2002;Szumik and Goloboff, 2004;Santos and Fuhlendorf, 2019). Three different cell grids were set to examine the effect of the cell size in inferring the distribution patterns.…”

Species richness patterns and endemism on the large-scale play a significant role in biogeography and biodiversity conservation. This study aimed to explore the diversity centers and endemic areas of a large cantharid genus Lycocerus, so as to test whether the hypothesis of montane and island systems biodiversity in previous studies was supported. In this study, a comprehensive species’ geographical database on the global scale consisting of 4,227 records for 324 Lycocerus species was compiled and analyzed. Species richness pattern was mapped into a grid-based map with a spatial resolution of 1° × 1° fishnet. An unbalanced pattern was identified, and it showed that the centers of species richness of Lycocerus were situated in Eastern Himalayas, Hengduan Mountains, Eastern Sichuan Mountains, Taiwan, and Japan. Further analyses based on two approaches, including parsimony analysis of endemicity (PAE) and endemicity analysis (EA), were applied to detect areas of endemism (AOEs) at three different grid sizes (1°, 1.5°, and 2°). Finally, a total of nine AOEs were detected, including five montane areas (Himalayan areas, Hengduan Mountains, South edge of China, Eastern China Mountains, and Eastern Sichuan Mountains), three islands (Taiwan Island, Japan, and Korean Peninsula), and one plateau (Shan Plateau), which were generally consistent with the species richness pattern. The results verify that montane and island systems have an essential role in promoting the formation of diversity centers and AOEs because of their complex topography, varied habitat and geological events.

“…A spreadsheet with the geographical records of the sampled species was saved as a .csv file and converted into an .xyd file using the gex online tool (http://gex.mfuhlendorf.com/) (Santos & Fuhlendorf, 2019). The analysis was run using a grid of cells of three different sizes (0.1°, 0.2°, and 0.3°).…”

The delimitation of conservation units may be supported by information on compositional (taxonomic), functional, and phylogenetic diversity of a given locality or region. In this context, systematic conservation planning and key biodiversity areas are promising approaches for biodiversity protection. Factors such as species representativeness and exclusivity may be used to identify geographical distribution patterns and select relevant areas for conservation at a local scale. This study aims to identify areas with rare and restricted fish species in mountain streams in Southern Brazil, using a method that unites ecological and biogeographical approaches. Seven river basins and 152 mountain streams in Southern Brazil were sampled to obtain data on the occurrence and abundance of 115 fish species. The rarity status of each species was determined and endemicity analysis was used to find areas of restricted species (ARS) with three cell sizes. Using larger cells, continuous areas were identified and supported by a higher proportion of rare fish species. Using smaller cells, discontinuous areas were identified within each of the river basins, where rare and endemic fish species occur. Most of the smaller areas relevant for protecting fish fauna were located outside of conservation units. Fundamental areas were selected for the protection of fish species in mountain streams in Southern Brazil. Both the method proposed and the areas with rare and restricted fish species identified may be used to support systematic conservation planning and to delimit new priority areas for conservation.

“…The registered localities are summarised in Figure 1. An XYD file (Appendix ) was built using GeX (Santos & Fuhlendorf, 2018) and it was analysed with NDM/VNDM (Szumik et al . 2002; Szumik & Goloboff, 2004), a method that delimits areas of endemism.…”

This article explores the distributional data of 2440 occurrence records for 1415 Tipulomorpha (Insecta: Diptera) species to search endemism patterns in the Afrotropical region and to propose a regionalisation scheme. The results were compared to areas of endemism proposed in previous works for other taxa. Areas of endemism were established using NDM/VNDM based on a grid size of 8° and consensus cut‐off of 24%. In this study, five subregions were found: Arabian, Atlantic, Indian, Southern Africa and Central Africa. These subregions are divided into 12 dominions: Arabian Peninsula, Atlantic Islands, Central Africa, Central Madagascar, Eastern Africa, Indian Ocean, Northwestern Africa, Southeastern Africa, Southern Africa, Southern Madagascar, Southwestern Africa and Western Africa. There is a general congruence of the dominions with the distribution of the main hydrographic basins and divisions of the forests of Madagascar.
