“…Alternatively, it could indicate ecological gradients, possibly enforced by Pleistocene glaciations, prompted speciation through so called “speciation pumps”(Hu et al, 2021), and species rich regions emerge at the junction of species from different elevations. Intensified speciation at mountain slopes is well-known for freshwater amphipods in general (Copilaş-Ciocianu & Petrusek, 2015; Liu et al, 2023; Mamos, Wattier, Majda, Sket, & Grabowski, 2014) and Niphargus in particular (Delić et al, 2021; Lefébure et al, 2007; Stoch, Salussolia, & Flot, 2022). Interestingly, the map showing the biodiversity pattern of MOTUs is similar to the map showing biodiversity pattern of clades (Fig.…”

Aim: Morphologically cryptic species are an important part of global biodiversity, yet it remains unclear how these species contribute to and integrate into communities at different geographic scales. It is especially unclear at which scales they co-occur, and if and how their ranges overlap. To adequately protect biodiversity, an accurate understanding of the underlying processes and adequate level of protection is needed, in particularly for often overlooked cryptic species. Question: We analyzed patterns of syntopies (local co-occurrences) and sympatries (range overlap) to test how the evolutionary origin of cryptic species shapes biodiversity patterns at different geographic scales. We hypothesized i) that syntopies are more common among phylogenetically deeply divergent cryptic species than among close relatives, and ii) that sympatries are an outcome of phylogenetic relatedness and dispersal, with range size as a proxy of dispersal ability. Location: Western Europe. Taxon: Subterranean amphipod crustaceans of the polyphyletic Niphargus rhenorhodanensis species complex. Methods: Unilocus species delimitations (PTP, ASAP), calibrated multilocus phylogenetic analyses, co-occurrence analyses using a probabilistic model, generalized linear models (GLM). Results: The studied species complex comprises 37-48 molecular operational taxonomic units (MOTUs) from nine different clades. Syntopies are random or less frequent than expected, implying an insufficient between-MOTU differentiation allowing stable coexistence. GLM suggested that age of divergence does not predict species sympatries, although they emerge more frequently among MOTUs from different clades. By contrast, sympatries emerge when at least one MOTU disperses over a large geographic range. Biodiversity rich regions were found at the foothills of the Alps, the Jura and the Central Massif, regardless the inference method. Main conclusions: Biodiversity patterns of the herein studied species complex are driven mainly by dispersal and reflect geographic circumstances of speciation. While species richness on a local scale may be the outcome of competition and dispersal, regional biodiversity patterns emerged through biogeographic history on a clade-level.

With a history of 96 years, the Institute of Zoology (IOZ) is one of the oldest scientific research institutions of the Chinese Academy of Sciences (CAS). Since its establishment, IOZ has consistently served the national strategy and pursued the forefront of science. Since 1978 when China implemented a reform and opening up policy, especially over the past two decades, IOZ has achieved a series of world-leading science and technology achievements, deepening our understanding of mechanisms of cell programming and reprogramming, reproductive and developmental regulation, stem cell and regenerative medicine, integrated management of pest insects and rodents, endangered mechanisms and conservation of species, and animal taxonomy and evolution. In the future, IOZ will strive to seize the science highland by optimizing the layout of its disciplinary development, attracting and fostering talents, and constructing world-class research facilities and platforms, aiming to be a leading institution for the continuous innovation and development of life science both in China and the world.
