TL;DR
Using molecular and morphological data to study a group of closely related and morphologically very similar deep-sea ostracods from the Aleutian Basin and Bering Sea, insight is provided into the role of environmental and hydrodynamic processes in the evolutionary patterns of deep-sea organisms.
Accurate species delimitation is essential for understanding the evolutionary processes that generate and maintain biodiversity, particularly in marine systems characterized by high connectivity and widespread distributions. Reef-associated fishes of the Indo–West Pacific provide an ideal framework to investigate t...
Abstract Pleistocene marine transgressions and regressions repeatedly inundated and exposed the Southeastern Brazilian coast, creating alternating phases of connectivity and isolation among adjacent river drainages, that may have structured freshwater fish diversification. We integrate mitochondrial (COI, CytB) and nuc...
Ischyropsalis C.L. Koch, 1839 is a genus of harvestmen inhabiting both terrestrial surface habitats and caves in central and southern Europe. The accepted number of species is controversial due to feature similarities and their strong sexual dimorphism. The northern part of the Iberian Peninsula harbours 16 accepted sp...
The new species Bathynomus tuebingoborikensis sp. nov., discovered in an historic museum collection, is described. We provide preliminary phylogenetic analyses of the genus, including extant and fossil species, using morphological characters. We reconstruct the evolutionary origin of the genus in the Caribbean, and sug...
The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to t...
The genus Nectogale, endemic to the Himalayas, Hengduan Mountains, and adjacent ranges, comprises highly specialized semi-aquatic shrews adapted to high-elevation streams. Its diversity has likely been underestimated because of limited sampling and morphological conservatism, leaving species limits and evolutionary rel...
