No full textFIGURE 3. Currently available descriptions across different families. The 5 number columns show the number of species in each family (species), the number of species with descriptions or without (desc, no desc), the percentage of species with descriptions (percent), and the number of species without (left). The left bar chart shows the percentage of species with/out descriptions (blue/yellow). The right bar chart shows the absolute number of species with/out descriptions (blue/orange). Note that Iguanidae contains all 8 families now considered Iguanidae (s.l.), e.g. Opluridae etc. The Lamprophiidae (s.l.) also contain Atractaspididae, Psammophiidae, and Pseudoxyrhophiidae. Gymnophthalmidae (s.l.) contain Alopoglossidae and Anguidae (s.l.) contain Diploglossidae.Published as part of <i>Uetz, Peter, Darko, Yaa Adarkwa & Zeliff, Dustin, 2023, Towards digital descriptions of all extant reptile species, pp. 27-42 in Megataxa 10 (1)</i> on page 32, DOI: 10.11646/megataxa.10.1.6, <a href="http://zenodo.org/record/10149170">http://zenodo.org/record/10149170</a>
FIGURE 1 in The disconnect between DNA and species names: lessons from reptile species in the NCBI taxonomy database
No full textFIGURE 1. Relationship between databases, such as the NCBI Taxonomy, the Reptile Database, and other taxonomic databases and data sources. Some of the resources shown are examples for other data resources not shown. Arrows indicate data flow or referencing (linking) between databases. For instance, iNaturalist uses names from the Reptile Database, with the latter linking back directly to iNaturalist species pages. Arrows to and from collections (and collection data aggregators such as VertNet) indicate cross-referencing of specimens, but not necessarily hyperlinks.Published as part of Garg, Akhil, Leipe, Detlef & Uetz, Peter, 2019, The disconnect between DNA and species names: lessons from reptile species in the NCBI taxonomy database, pp. 401-407 in Zootaxa 4706 (3) on page 402, DOI: 10.11646/zootaxa.4706.3.1, http://zenodo.org/record/357078

No full textFIGURE 1. The use of abbreviations in reptile species descriptions has increased steadily. (A) The total number of abbreviations used in species descriptions described in a given year. (B) The number of species that use abbreviations in species descriptions since 1982. In (B) year indicates the year when the description used in our analysis was published, not the year when a species was formally described. Note that the last data points in A and B represent only 7 months of the year 2022.Published as part of Darko, Yaa Adarkwa, Voss, Olaf & Uetz, Peter, 2022, A dictionary of abbreviations used in reptile descriptions, pp. 421-432 in Zootaxa 5219 (5) on page 424, DOI: 10.11646/zootaxa.5219.5.2, http://zenodo.org/record/743136
FIGURE 1 in Towards digital descriptions of all extant reptile species
No full textFIGURE 1 Species descriptions in the Reptile Database over time and ranked by information content. (A) Timeline over which descriptions have been added to the Reptile Database. (B) Descriptions ranked by "size". Each species with a description is shown as a vertical bar, with the hight indicating its size in characters (i.e., "bytes" or letters without spaces, Y axis). The X axis shows the ranked series of species. One example is shown in the insert, namely the description of Lampropeltis alterna. This description has 623 characters and is on the shorter end of the spectrum. The tail end of this graph shows ~700 species in which the description only consists of a reference, e.g., "Description: McDowell 1979: 51" (here: for Candoia aspera Ģnther 1877), hence they are very short.Published as part of <i>Uetz, Peter, Darko, Yaa Adarkwa & Zeliff, Dustin, 2023, Towards digital descriptions of all extant reptile species, pp. 27-42 in Megataxa 10 (1)</i> on page 29, DOI: 10.11646/megataxa.10.1.6, <a href="http://zenodo.org/record/10149170">http://zenodo.org/record/10149170</a>

The original descriptions of reptiles and their subspecies
Full text linkBy August 2017 an estimated 13,047 species and subspecies of extant reptiles have been described by a total of 6,454 papers and books which are listed in a supplementary file. For 1,052 species a total of 2,452 subspecies (excluding nominate subspecies) had been described by 2017, down from 1,295 species and 4,411 subspecies in 2009, due to the elevation of many subspecies to species. Here we summarize the history of these taxon description beginning with Linnaeus in 1758. While it took 80 years to reach the first 1,000 species in 1838, new species and subspecies descriptions since then have been added at a roughly constant rate of 1000 new taxa every 12-17 years. The only exception were the decades during World Wars I and II and the beginning of this millennium when the rate of descriptions increased to now about 7 years for the last 1,000 taxa. The top 101 most productive herpetologists (in terms of “taxon output”) have described more than 8,000 species and subspecies, amounting to over 60% of all currently valid taxa. More than 90% of all species were described in either English (68.2%), German (12.7%) or French (9.3%).
