Links to useful amphibian systematic, conservation, collection management, informational, and/or regional sites

Amphibia.my: http://amphibia.my/index.php. This website provides photographs and basic information on the frogs of peninsular Malaysia. 

Amphibian Karyotype Data: https://evobir.shinyapps.io/AmphibianDB/ . A database allowing access to karyotypic information on all species of amphibians for which these data have been published. 

AmphibiaWeb: http://www.amphibiaweb.org/. An important site for access to information on amphibian conservation, population declines, as well as other general information about and images of many amphibian species, directed at the informed public and conservation scientists. The taxonomy tends to run far behind the community, particularly in salamanders and the species accounts, many/most written by undergraduates, are ok places to start but should not be the sole source of information. 

AmphibiaWeb links to frog callshttp://research.amnh.org/vz/herpetology/amphibia/index.php. Useful access to many recordings. 

AmphibiaWeb Amphibian Biology Resources: https://amphibiaweb.org/resources/biology.html. Listing of a great number of links to specialized amphibian websites.

AmphibiaChina: http://www.amphibiachina.org/ (Mandarin); https://translate.google.com/translate?hl=en&sl=zh-CN&u=http://www.amphibiachina.org/&prev=search (English translated page). A website dedicated to providing information on the Chinese amphibian fauna. 

Anfíbios de Colombia: http://www.batrachia.com/. One of the very best and up-todate websites for one country and because Colombia is a serious hot-spot of amphibian diversity this is a very useful site. 

Anfibios de Ecuador: https://bioweb.bio/faunaweb/amphibiaweb (splash page); https://bioweb.bio/faunaweb/amphibiaweb/BusquedaEspecies (query page). A very up-to-date site on the amphibians of Ecuador, one of the most biodiverse countries in the world. Species records are linked from the relevant species records in ASW. 

Arctos: https://arctos.database.museum/home.cfm (splash page). Arctos is an ongoing effort to integrate access to specimen data, collection-management tools, and external resources on the internet. 

CalPhoto Images: http://calphotos.berkeley.edu. A great resource for images, maintained by Biodiversity Sciences Technology (BSCIT), part of the Berkeley Natural History Museums at the University of California, Berkeley.

CaribHerps: http://www.caribherp.org/ . Great source of images and maps for the islands of the Caribbean. 

Catalogue of Life: http://www.catalogueoflife.org/. A site the provides taxonomic information on all taxa of life. Useful for rapid look-ups of currently accepted names and spelling and because it is funded by various European sites, not subject to the vagaries of the U.S. National Science Foundation and therefore likely to grow as an important resource. 

Dendrowikihttp://www.dendrowiki.org/alle.html. A site providing images for species of dendrobatoid frogs (Aromobatidae and Dendrobatidae). 

EncicloVidohttp://enciclovida.mx/. An access point to online information about the animals of Mexico. 

Encyclopedia of Life (Amphibia page): http://www.eol.org/pages/1552. On the way to becoming an amazing resource for information on all species of life. The tie-in to the Biodiversity Heritage Library should make this site very useful for professionals.

Frogs of Australia: https://frogs.org.au/frogs/index.html. A good source for photographs and range maps. Appears to lag substantially behind the state of systematics.

Frogs of Borneo: http://frogsofborneo.org/. A good source for information and images of the species of Borneo.

Herpetological Taxonomy and Systematicshttps://www.facebook.com/pages/Herpetological-taxonomy-and-systematics/751055144919750. A source of recently named species and taxonomic change in herpetology. Does a good job of reporting new taxa. 

Global Biodiversity Information Facility (GBIF, Amphibia page)https://www.gbif.org/species/131. Search on species names for range maps and access to dot maps and links to specimen several databases and websites. Useful for professionals with reasonable caution inasmuch as IDs in major collection often need to be verified. An exceedingly useful website for professionals in conservation biology and systematics. Collection data appear to overlap extensively with those of VertNet. 

Google: http://www.google.com/. The fastest way to locate information, albeit disorganized, on any taxon is to search for it on Google. But, like any unvetted information source, errors exist.

Google Scholar: https://scholar.google.com/. A more refined version of Google for accessing primary and secondary scientific literature. I use it all of the time. 

Herpetofauna Mexicana: https://www.facebook.com/groups/herpmex/. Discussion group of the Mexican herpetofauna. 

HerpMapper: http://herpmapper.org/. A citizen scientist site designed to gather and share information about reptile and amphibian observations/photographs/range maps from across the planet. Requires registration to use effectively but individual species can be searched by using the format http://herpmapper.org/records?taxon=Genus+species. 

iNaturalisthttps://www.inaturalist.org/. A citizen scientist site at the California Academy of Science that does a great job of keeping up with amphibian taxonomy and it has also allowed me in some cases (like Incilius nebulifer) to check photographs of extralimital records. While identifications should be used with reasonable caution, the system provides considerable feedback from users to correct misinformation. I am impressed. 

ITIS (Integrated Taxonomic Information System: ITIS Amphibia record). ITIS is a United States Department of Agriculture system for storing information on all organismal names. ITIS nomenclature is employed by U.S. Federal agencies for purposes of communication among agencies and, in some cases, apparently for purposes of permitting. A useful site. 

IUCN Red List: https://www.iucnredlist.org/. A website that provides information on conservation status and maps drawn by regional experts for many species of amphibians. This is a canonical site for conservation information although it lags behind the systematics community due to financial constraints. And, in aggregate it illustrates just how little baseline data exists on amphibian population sizes, declines, range changes, and extinctions we have on just about any of these species. See Ficetola, Rondinini, Bonardi, Padoa-Schioppa, and Angulo, 2014, J. Biogeograph., 14: 211–221, for discussion of accuracy. 

IUCN SSC Amphibian Specialist Group: https://www.iucn-amphibians.org/ . Access to various sites addressing amphibian conservation and the people on point for these activities. 

Map of Life: https://mol.org/. An increasingly important mapping program for the planet's biodiversity. Search for species' maps at https://mol.org/species/.  

Mikko's Phylogeny Archive: http://www.helsinki.fi/~mhaaramo/metazoa/deuterostoma/chordata/amphibia/lissamphibia/lissamphibia.html . A useful and accurate site for access to phylogenetic information and comparisons of different taxonomic arrangements. 

National Amphibian Atlas: http://igsaceeswb00.er.usgs.gov:8080/mapserver/naa/. This site contains reasonably good maps of the distributions of amphibians in the United States, although in some cases counties seem to be the unit of occurrence, and without accompanying text it is difficult to evaluate the sometimes significant differences between these maps and those in the more traditional field guides.

SystTax: http://www.biologie.uni-ulm.de/systax/ . An online German GBIF database for systematics and taxonomy, relevant to us because it provides access to the ZMB type collection of amphibians, at least so far in my viewing, with images. A useful search string for querying ZMB amphibian types is: http://www.biologie.uni-ulm.de/cgi-bin/query_all/query_all.pl?query=genus+species , where genus and species name of the original type is entered. Apparently SysTax also allow access into collection records of a large number of German systematic collections, including the Senckenberg Naturhistorisches Sammlungen Dresden, but I have not investigated any of these other institutions.  

Translations of the Scientific Names of the Reptiles and Amphibians and Amphibians of North America: http://ebeltz.net/herps/etymain.html. Lots of interesting and helpful biographical and etymological information on USA and Canadian amphibian and reptile names from the indefatigable Ellin Beltz.

Tree of Life: http://tolweb.org/tree?group=Living_Amphibians&contgroup=Terrestrial_vertebrates. This site (not associated with the NSF Assembling-the-Tree-of-Life Program, which marked the rather corrupt end to substantial support of systematics efforts by the U.S. National Science Foundation, which is now funding at something like 4.5% of received proposals in organismal biology) provides a basic source of information regarding the evolutionary history for all major taxa of amphibians optimized on educational outreach. The contents and badly "under construction" and substantially out of date in most amphibian groups. A great concept, however.

VertNet: http://portal.vertnet.org/. Similar to GBIF and Arctos specimen data access, this valuable site ties together collection data for most of the important herpetology collections in North America. Of great utility to biodiversity specialists but likely to be over-interpreted by naive informaticists. Overlaps with Arctos and GBIF and (above). 

Wikipedia: http://www.wikipedia.org. While Wikipedia overall is a remarkable resource for general information and is self-policed relatively well, the English version has from time to time contained considerable taxonomic misinformation and/or misinformation promoted by unethical persons with only a passing relationship with the truth. I have tried to fix some of the egregious propaganda, only to find the misinformation back again the next day. This finally came to the attention of Wikipedia editors who have gotten control of the problem, but caution is warranted. Having written that, I must comment on the fact that the French and Spanish versions of Wikipedia (http://fr.wikipedia.org/ and http://es.wikipedia.org/, respectively) seem to be doing a responsible job towards taxonomy generally and amphibians specifically.  

Wikispecies: http://species.wikimedia.org/wiki/Main_Page. A website that intends to have a page for every taxon. Unfortunately, like Wikipedia, although it is improving, a significant amount of the content related to amphibian systematics occasionally contains records that are either poorly researched or is simply reflect misinformation by people with big political agendas.
