“…If the levels of cryptic diversity found in recent studies are representative, this suggests that (at a minimum) several hundred gecko species remain unrecognized. Recent molecular studies of frogs from Latin America (Fouquet et al 2007) and Southeast Asia (Stuart et al 2006) also show that cryptic species complexes are common in other vertebrate groups. Clearly, worldwide diversity in many vertebrate groups remains seriously underestimated.…”

Cryptic diversity in vertebrates: molecular data double estimates of species diversity in a radiation of Australian lizards (Diplodactylus, Gekkota)

A major problem for biodiversity conservation and management is that a significant portion of species diversity remains undocumented (the ‘taxonomic impediment’). This problem is widely acknowledged to be dire among invertebrates and in developing countries; here, we demonstrate that it can be acute even in conspicuous animals (reptiles) and in developed nations (Australia). A survey of mtDNA, allozyme and chromosomal variation in the Australian gecko, genus Diplodactylus , increases overall species diversity estimates from 13 to 29. Four nominal species each actually represent multi-species complexes; three of these species complexes are not even monophyletic. The high proportion of cryptic species discovered emphasizes the importance of continuing detailed assessments of species diversity, even in apparently well-known taxa from industrialized countries.

“…The occurrence of cryptic species also has important repercussions for conservation; in an area of Southeast Asia with the highest relative rate of deforestation in any tropical region, studies of forest dwelling frogs have revealed at least 14 species within two nominal species. These were both thought to be geographically widespread, but instead represent multiple species with smaller geographic ranges, and therefore greater vulnerability to extinction (Stuart et al, 2006). Such findings illustrate the importance of accurate assessments of diversity and distributions to enable appropriate management and thereby reduce the risk of extinctions of evolutionary lineages.…”

a b s t r a c tBumblebees are ecologically and economically important, and some species have suffered dramatic population declines. The absence of morphological diagnostic characters for the identification of some species creates difficulties for basic ecological studies, and for conservation management. The widespread and commercially exploited bumblebee subgenus Bombus sensu stricto contains a cryptic species complex, known as the lucorum complex, which in Europe comprises B. lucorum, B. cryptarum and B. magnus. Little is known about these species and much of what has been reported is likely to have suffered from incorrect identification. Although the lucorum complex as a whole is common in Great Britain, we aimed to determine whether the populations of the individual species are vulnerable and require conservation action. Using genetic methods to distinguish them, we determined the geographic distribution and abundance of the lucorum complex species in Great Britain, and assessed the extent of niche differentiation between these species. We detected major differences in the geographic range, forage use and sensitivity to summer temperatures of the three species. Bombus lucorum was found to have the broadest distribution and diet, being present throughout mainland Great Britain, whereas B. cryptarum and B. magnus were absent from large areas of central and southern England. Bombus cryptarum and B. magnus were more likely to be found at sites with lower summer temperatures. Bombus magnus, the least abundant species, was found to exhibit an unusually tight biotope association with heathland habitat. This has conservation implications for B. magnus given the current threats to this habitat type.

“…The increasing utilization of molecular data has reinforced the conclusion that morphological evolution in amphibians is often cryptic (e.g. Chek et al, 2001;Cherry et al, 1977;Hass et al, 1995;Maxson, 1984;Richards and Moore, 1996;Stuart et al, 2006) and has led to a revitalization of amphibian taxonomy. Many groups of amphibians are morphologically conserved and depauperate in obvious external characters.…”

Few studies to date have examined genetic variability of widespread tropical amphibian species over their distributional range using diVerent kinds of molecular markers. Here, we use genetic data in an attempt to delimit evolutionary entities within two groups of Neotropical frogs, the Scinax ruber species group and the Rhinella margaritifera species group. We combined mitochondrial and nuclear markers for a phylogenetic (a total of »2500 bp) and phylogeographic study (»1300 bp) to test the reliability of the currently accepted taxonomic assignments and to explore the geographic structure of their genetic variation, mainly based upon samples from the French Guianan region. Phylogenetic analyses demonstrated the polyphyly of Scinax ruber and Rhinella margaritifera. S. ruber consists of six lineages that may all merit species status. ConXicting signals of mitochondrial and nuclear markers indicated, among some Scinax lineages and species, the possibility of ongoing hybridization processes. R. margaritifera consisted of 11 lineages which might represent distinct species as well. Phylogeographic analyses added further information in support of the speciWc status of these lineages. Lineages of low divergence were found in sympatry and were reciprocally monophyletic for mitochondrial as well as nuclear genes, indicating the existence of young lineages that should be awarded species status. Our results highlight the utility of combining phylogenetic and phylogeographic methods, as well as the use of both mitochondrial and nuclear markers within one study. This approach helped to better understand the evolutionary history of taxonomically complex groups of species. The assessment of the geographic distribution of genetic diversity in tropical amphibian communities can lead to conclusions that diVer strongly from prior analyses based on the occurrence of currently recognized species alone. Such studies, therefore, hold the potential to contribute to a more objective assessment of amphibian conservation priorities in tropical areas.
