Collecting much-needed information on the taxonomy, distribution, and ecology of cave-dwelling shrimp is vital for addressing urgent challenges in conservation biodiversity fragile cave ecosystems. Caridina incolor sp. nov. , a new atyid from an underground stream Yaoshui Cave, Daqikong scenic area, Libo County, Guizhou Province, southwestern China described based morphology DNA analysis (mitoc...

Caves possess a continuum of ecological zones that differ in their microhabitat conditions, resulting gradient nutrients, climate, and illumination. These conditions engender relatively rapid speciation diverse assemblages highly specialised spider fauna. It is unclear, however, how zonation these caves affects assemblage composition structure. Surveys 35 Levantine were conducted to compare the...

Talitrids are a highly diverse group of amphipod crustaceans that have colonized various terrestrial habitats. Three genera successfully adapted to cave habitats on islands in the Pacific and Atlantic Oceans. However, evolutionary origin troglobitic talitrids has remained unknown. We estimate phylogenetic position Minamitalitrus zoltani, which inhabits limestone caves Minamidaito Island Northwe...

The troglobitic (exclusively subterranean source population) catfish Ituglanis passensis (Siluriformes, Trichomycteridae) is endemic to the Passa Três Cave, São Domingos karst area, Rio Tocantins basin, Central Brazil. This unique population presents variably reduced eyes and melanic pigmentation. We describe reproduction early development in this species based on a spontaneous (non-induced) re...

Dedicated ichthyological surveys in four active karstic caves the Mexican state of Chiapas (Grijalva River drainage basin) resulted discovery same number hypogean populations Rhamdia catfishes assignable to two different species: R. laticauda and guatemalensis . The taxonomic identity these was initially determined based on morphological traits subsequently corroborated with molecular data a ph...

Two new species of Hyalella S.I. Smith, 1874 are described from state Jalisco, Mexico. marysolae sp. nov. can be identified by the presence small projections or carinae on pleonites 1−2, with first antenna being composed 12 articles and second 15 articles. The maxilla bearing 2−3 distal pappose setae, propodus in male gnathopod is hammer-shaped. Conversely, H. morronei nov., dorsal absent 10 14...

A new planthoppers genus and species of CixiidaeOecleini, Coframalaxius bletteryi gen. nov. sp. newly discovered in a cave near Nice southern France, is described. Molecular analysis confirms the morphology-based classification as sister to Trigonocranus within Oecleni. Several morphological characters are further discussed. double-grasping coxo-femoral femoro-tibial system regarded apomorphic ...

The effects of long-term starvation and subsequent refeeding on haematological variables, behaviour, rates of oxygen consumption and intermediary and energy metabolism were studied in morphologically similar surface- and cave-dwelling salamanders. To provide a hypothetical general model representing the responses of amphibians to food stress, a sequential energy strategy has been proposed, sugg...
