Background The Tibetan Plateau is not only the highest and largest plateau on earth; it also home to numerous freshwater lakes potentially harbouring endemic faunal elements. As remains largely unknown whether these have continuously existed during Last Glacial Maximum (LGM), questions arise as taxa been able exist since before latest Pleistocene, from where how often was colonized, by which mechanisms organisms conquered remote high altitude lentic systems. In this study, species of...

The Himalayas are considered to constitute a biogeographical boundary between the Palaearctic and Oriental regions. However, this mountain range does not form uniform barrier because several large river valleys deeply cut into Himalayas, crossing drainage divides potentially forming dispersal corridors, particularly for freshwater organisms. In present study, effectiveness of these corridors is tested first time based on molecular data, using amphi-Himalayan gastropod genus Gyraulus as model...

Sphaeriids represent a highly diverse family of small bivalves inhabiting freshwater habitats worldwide. They are recognized for their high dispersal capacity as well capability to adapt such extreme environments mountain regions over 4,000 m above sea level (a.s.l.). The Tibetan Plateau, located in central Asia, is elevation area. Here, we present the first broad spatial sampling sphaeriids from which allowed us describe Recent fauna biogeographical background. Our study revealed six...

Most of the present knowledge on animal reproductive mode evolution, and possible factors driving transitions between oviparity viviparity is based studies vertebrates. The species rich door snail (Clausiliidae) subfamily Phaedusinae represents a suitable unique model for further examining parity as three different strategies, oviparity, viviparity, intermediate embryo-retention, occur in this group. study reconstructs evolution strategies time-calibrated molecular phylogenetics,...

The high-elevation Tibetan Plateau (western China) is inhabited by a unique, though not particularly species-rich, community of organisms. We explored the species content and evolutionary history endemic freshwater snail genus Tibetoradix. Phylogenetic relationships within were reconstructed based on available sequence data. used single-rate Poisson Tree Processes approach for delimitation compared putative species-level clades with already described taxa. found that consists at least 6...

Patagonia and the Tibetan Plateau both harbor various freshwaters with relatively low temperatures. Pulmonate freshwater gastropods are widely distributed in these water bodies. Both regions, however, also possess a number of geothermal hot springs. Such springs might have served as refugia for taxa during Pleistocene. In present study, two spring systems, one at Plateau, were examined. Individuals Chilina patagonica (in Patagonia) well Radix cf. auricularia Gyraulus sp. (at Plateau) found...

Abstract The insular limestone karsts of northern Vietnam harbor a very rich biodiversity. Many taxa are strongly associated with these environments, and individual species communities can differ considerably among karst areas. exact processes that have shaped the biotic composition habitats, however, remain largely unknown. In this study, role two major for assembly snail on was investigated, interspecific competition filtering due to geographical factors. Communities operculate land snails...

Limestone karsts can form terrestrial habitat islands for calcium-dependent organisms. In Vietnam, many karst habitats are threatened, while their rich biodiversity is still far from being thoroughly explored. Given that conservation of biota strongly relies on correct species identification, the presence undetected cryptic pose severe problems. The present study focuses diversity among karst-inhabiting land snails genus Cyclophorus in northern where specimens with a similar shell morphology...

VIETBIO [Innovative approaches to biodiversity discovery and characterisation in Vietnam] is a bilateral German-Vietnamese research capacity building project focusing on the development transfer of new methods technology towards an integrated monitoring system for Vietnam. Dedicated field training testing innovative methodologies were undertaken Cuc Phuong National Park as part with support project, which led data records made available this article collection. collaboration between Museum...

Y-axis orientation, a movement perpendicular to the shore or coastline, enables aquatic animals stay in preferred zone generally unstable habitats. Such behaviour is widespread phenomenon many freshwater and intertidal animal taxa. In present study, an arena approach was used test orientation response of pulmonate snails. Using this experimental design, shown for first time snail species, riverine Chilina patagonica. Some cues, potentially mediating appeared play no role behaviour, such as...
