Another problem, such as the lack of professionalization of government agencies like those of emerging economies consercacion as Mexico, could break the flow of information about new species and taxonomic changes of the involved taxa.

In other regions of the world such as the Americas, habitat loss plus habitat degradation are the main factors in turtle population reduction.

University of California Press; A call for papers is issued periodically for scholars, non-profit organizations, and research institutions to submit proposals for species to be included in the list. Patterns of richness and endemism of the Mexican herpetofauna, a matter of spatial scale?.

Most of the increase corresponds with the inclusion of the genus Terrapene and to other taxonomic updates to the list. A single point inside a hexagon was consider a taxon distributed throughout the entire hexagon, then the sum of all the hexagons with records was used as a proxy for the species’ distribution. The conservation status of the freshwater and terrestrial turtles of Mexico: A method for siting parks and reserves with special reference to Colombia and Ecuador.

The conservation status of the world’s reptiles. We included each threat category in our database and conservaccion recorded whether or not each species was endemic to Mexico.


Society for the Study of Amphibians and Reptiles; conservvacion Mexican government agencies such as Semarnat Ministry for Environment and Natural ResourcesConabio National Commission for the Study of Biodiversity – a scientific authorityProfepa Federal Attorney for Environmental ProtectionInecc National Institute of Ecology and Climatic Change – a scientific authority and policy makerCNF National Commission of Forestryand DGVS General Directorate of Wildlife – part of Semarnat, and in charge of regulating wildlife management and game are in charge of listing threatened species, protecting the listed species, designing and developing conservation programs for native species, and removing introduced species Semarnat, The Central American river turtle Dermatemys mawiithe desert tortoises Gopherus spp.

The dazed and confused identity of Agassiz’s land tortoise, Gopherus agassizii Testudines, Testudinidae with the description of a new species, and its consequences for d.

Limits to the use of threatened species lists. Threatened, endangered and vulnerable tree species: What is the logic of international cooperation agreements on conservation biology if the information exchange is not consistent or even ignored?

The Conabio List of Priority Species Conabio, is another list issued by the Mexican government and is based upon a closed workshop of specialists from the federal government, academia, national non-governmental organizations NGOsinternational NGOs such as the IUCN, and private consultants non-academics, but experts on conservation biology. To determine the area of occupancy categories, we sampled all of SNIB’s records in the following way: The results generated in this paper expose several concerns about turtle conservation biology conservacino Mexico and probably in biolobia lineages.

Chelonian Research Monographs 5. All of these taxa are endemic with marginal to very restricted distribution areas. We explored the overlap of conservation status dee Mexican and international agencies by comparing listing status. To sample and calculate the approximate species area of occupancy we used a grid of 1, hexagons with an area of km 2 each.

Mollecular Phylogenetics and Evolution. La tortuga blanca Dermatemys mawiilas tortugas terrestres Gopherus spp. Certainly both succeed and fail, but the confusion generated by the lack lx concordance makes conservation efforts difficult. The world’s most endangered tortoises and freshwater turtles. This situation merits the following questions: We want to thank John Legler and Richard Vogt for inviting us to the Symposium on Mexican Turtles at the 11th Turtle Survival Alliance TSA meeting, at which the original ideas for this paper were presented and discussed in an early stage.

Turtles of the world, 7th edition: As a general trend, the NOM generally lacks the taxa included in the Red List, meanwhile the Red List is also lacking taxa that should be included according to their status in the NOM and their distribution ranges Table 3.

We reviewed each category and rpimack them according to the definitions of threats for each category IUCN, b ; Semarnat, The only data lie in the slight change in the number of species included in the list and the number of species that changed to threatened or in extinction risk from to Molecular phylogenetics of the mud and musk turtle family Kinosternidae.

We tracked the NOM over the three past versions to the species level conservscion because of the lack of subspecies availability data in the previous issues Sedesol, ; Semarnat,and the number of species included changed slightly from 23 into 28 inand to 29 in Oxford University Press;
