“…As species extinction rates are increasing faster than we can assess species, we strongly suggest a review of the MER, with the goal of making it easier to assess species, with independency among criteria due to information gaps, and with the use of information which is significant for conservation purposes. This is evident for species like the Habromys mice which inhabit in the most threatened ecosystem in Mexico, the cloud forest (CONABIO, 2010;CONABIO, 2014;Lamoreux, McKnight & Cabrera, 2015), a fact which by itself should be enough to enlist and protect them, despite the complexity that the current MER assessments implicate. …”

Background. Red Lists have been traditionally used as the instruments to guide conservation strategies to avoid extinctions. There is little objection to the idea that categorizing species according to their risk of extinction is a good way to prioritize and implement conservation actions; however, there is little consensus in the best way to do this categorization, and different countries have developed different methods according to their specific needs. The scope of this paper is to contrast the Mexican Risk of Extinction Assessment Method (MER) and the one used by the IUCN Red List, and test how simple, objective and transparent are them.Methods. In order to compare the we performed a search within IUCN´s data base to find species ranked as critically endangered which have not been assessed by the MER. We picked 5 species from the rodent genus Habromys and performed a literature review to assess them through the MER guidelines; we then compared the outcomes with UICN Red List.Results. The five assessed species of cloud forest rodents yield equivalent results through both the MER and IUCN assessments; however, the information asked for by the MER was scant for all the species, and we argue that the results of the assessments are thus not entirely objectives. Moreover, we found that the MER is not a simple method to use due to ambiguities of the criteria.Discussion. The aim of risk assessments is to clearly define the conservation status of a given species, displayed in a simple, transparent, objective, way, which can be relevant in terms of scope and impact on conservation actions. Unfortunately the MER does not fulfil all these requirements, potentially compromising conservation actions. As a result, we propose that it is time reevaluate the current version of the Mexican Risk of Extinction Assessment Method.PeerJ PrePrints | https://dx.doi.org/10.7287/peerj.preprints.1437v2 | CC-BY 4.0 Open Access | rec:

“…No salamander was found in the adjacent forest during the day. In addition, a single individual was found during a conservation assessment in April 2009 (Lamoreux, McKnight & Cabrera Hernandez, 2015). Thorius minutissimus has not been found sympatric with any other plethodontid species, although Bolitoglossa zapoteca is known from near the type locality.…”

We describe three new species of minute salamanders, genus Thorius, from the Sierra Madre del Sur of Oaxaca, Mexico. Until now only a single species, T. minutissimus, has been reported from this region, although molecular data have long shown extensive genetic differentiation among geographically disjunct populations. Adult Thorius pinicola sp. nov., T. longicaudus sp. nov., and T. tlaxiacus sp. nov. are larger than T. minutissimus and possess elliptical rather than oval nostrils; T. pinicola and T. longicaudus also have longer tails. All three new species occur west of the range of T. minutissimus, which has the easternmost distribution of any member of the genus. The new species are distinguished from each other and from other named Thorius in Oaxaca by a combination of adult body size, external morphology and osteology, and by protein characters (allozymes) and differences in DNA sequences. In addition, we redescribe T. minutissimus and a related species, T. narisovalis, to further clarify the taxonomic status of Oaxacan populations and to facilitate future studies of the remaining genetically differentiated Thorius that cannot be satisfactorily assigned to any named species. Populations of all five species considered here appear to have declined dramatically over the last one or two decades and live specimens are difficult to find in nature. Thorius may be the most endangered genus of amphibians in the world. All species may go extinct before the end of this century.

“…Along with the states of Tabasco, Veracruz, and Oaxaca, Chiapas is the worst state in Mexico for the adequacy of its drinking water system and infrastructure, and more than 50% of its population is rural (Conagua, 2015;Tardanico & Rosenberg, 2000). The water infrastructure appears to quite poor in Chiapas, but the situation is made worse by the fact that, historically, the federal commission overseeing the creation of new pipelines has looked for new watersheds instead of conserving and protecting existing ones or investing in practices that might improve efficiency of use (Lamoreux, McKnight, & Cabrera Hernandez, 2015). Chiapas is a poor state and its water resource management reflects this.…”
