“…The study thus provides an example of how molecular tools can contribute to the delimitation of species with extensive convergent morphologies, which in turn could have important conservation implications. Molecular tools, such as DNA sequencing, will undoubtedly continue to be of importance for resolving cryptic species complexes that are pervasive in cave environments (Lefébure et al, 2007;Trontelj et al, 2009;Neiber et al, 2012). Similarly, morphological differences between lifestages within a species are commonplace among crustaceans, and in many instances pose important challenges for organism identification and taxonomic classification.…”

Abstract:Anchialine caves contain haline bodies of water with underground connections to the ocean and limited exposure to open air. Despite being found on islands and peninsular coastlines around the world, the isolation of anchialine systems has facilitated the evolution of high levels of endemism among their inhabitants. The unique characteristics of anchialine caves and of their predominantly crustacean biodiversity nominate them as particularly interesting study subjects for evolutionary biology. However, there is presently a distinct scarcity of modern molecular methods being employed in the study of anchialine cave ecosystems. The use of current and emerging molecular techniques, e.g., next-generation sequencing (NGS), bestows an exceptional opportunity to answer a variety of long-standing questions pertaining to the realms of speciation, biogeography, population genetics, and evolution, as well as the emergence of extraordinary morphological and physiological adaptations to these unique environments. The integration of NGS methodologies with traditional taxonomic and ecological methods will help elucidate the unique characteristics and evolutionary history of anchialine cave fauna, and thus the significance of their conservation in face of current and future anthropogenic threats. Here we review previous contributions to our understanding of anchialine biodiversity and evolution, and discuss the potential of "speleogenomic" methods for future research in these threatened systems.

“…In general, species are considered cryptic if they have been erroneously classified as a single species because of a lack of distinct morphological features. DNA barcoding has revealed cryptic diversity in a variety of taxa (Nieberding et al, 2005;Bickford et al, 2006;Witt et al, 2006;Lefébure et al, 2007;Pauls et al, 2010). Lefébure et al (2006b) showed that clades of crustaceans diverging by more than 0.16 substitutions per site of the CO I gene as measured by patristic distances are likely to present distinct species.…”

“…Some authors (e.g., Bickford, 2006) have suggested a link between extreme environmental conditions and cryptic species. Extreme environments impose stabilizing selection on changes in morphology during speciation, resulting in morphological stasis (Rothschild and Mancinelli, 2001;Nevo, 2001;Lefébure et al, 2006a;Bickford, 2006;Lefébure et al, 2007). C. alpina is in general restricted to extreme habitat conditions of cold springs and crenal streams.…”

“…Harsh conditions occurring in such environments and emerging biological properties, such as general inability to tolerate temperatures above 13-15 • C and preference of temperatures slightly above 0 • C (Steinböck, 1942;Reynoldson, 1953;Beauchamp and Ullyott, 1932;Köhler, 1932, in Wright, 1974, might limit morphological divergence. Evidence for morphological stasis of groundwater amphipods (Lefébure et al, 2007;Trontjl et al, 2009) and spring-inhabiting snails (Benke et al, 2009) has been found. The concept that extreme environmental conditions favor the evolution of cryptic species still requires further evaluation.…”

Genetic diversity in the Alpine flatworm <i>Crenobia alpina</i>

Abstract. The freshwater flatworm Crenobia alpina (Platyhelminthes, Tricladida, Planariidae) lives almost exclusively in cold springs and crenal streams and possesses only limited dispersal ability. In this study fragments of the COI and 18S rRNA genes were used to estimate genetic divergences among 37 C. alpina populations from the European Alps. Phylogenetic analyses revealed five geographically and genetically distinct groups and at least 10 distinct lineages of C. alpina across the European Alps. Our study suggests that C. alpina represents a complex of numerous cryptic species. Speciation (allopatric and/or sympatric) may have been facilitated by the orogenetic activity of the Alps and the high habitat specificity.

“…Recently, genetic analysis of the Niphargus genus revealed many cryptic species (Trontelj et al 2009). Most of these species have narrow local ranges, but about 25% of them have been found in caves 100 km or more apart (Lefébure et al 2006, Lefébure et al 2007, Trontelj et al 2009). The latter is peculiar to N. arbiter Karaman G., 1984, N. fontanus Bate, 1859, N. illidzensis cf.…”

The freshwater fauna of nine caves in central Abkhazia, western Caucasus, revealed 35 species of stygobionts, including 15 new species to be described elsewhere. The number of species per station increased from the depth towards the entrance in caves Golova Otapa and Abrskila, becoming the highest in the epigean part. In both caves, two abundance peaks of aquatic invertebrates were registered: one in the entrance area, associated with the development of amphibiotic insect larvae, the other in the depths due to the high numbers of stygobionts. In Cave New Athos, the highest species richness and abundance were observed in large lakes. In caves Golova Otapa and Abrskila, two faunistic complexes with complementary distributions were found, the first due to amphibiotic insects in the cave entrance area, the second one composed of stygobionts in the deep areas. The impact of anthropogenic factors on aquatic cave communities was also noted. The stygobiotic faunas of all caves studied were clearly divided into three groups, following the number of river valleys in which they were situated. The stygobiont faunas of the caves located within one river valley appeared to be 50% similar. In contrast, the fauna composition of the stygobionts from caves situated in different valleys shared not more than 12% species in common. Stygobiotic shrimps and gastropod mollusks show profound local endemism. Stygobiotic Amphipoda penetrating the ground waters revealed wide distributions between cave systems within a single karst massif.
