Article Reference On a new species of the genus Cyprinotus (Crustacea, Ostracoda) from a temporary wetland in New Caledonia (Pacific Ocean), with a reappraisal of the genus
The New Caledonia archipelago is known for its high level of endemism in both faunal and floral groups. Thus far, only 12 species of non-marine ostracods have been reported. After three expeditions to the main island of the archipelago (Grande Terre), about four times as many species were found, about half of which are probably new. Here, we describe a new species, Cyprinotus drubea sp. nov., which is characterised mainly by the hyper-developed dorsal hump on the right valve, much larger than in any other known Recent species in this genus. After a literature study of the other presumed species in Cyprinotus Brady, 1886, we retain seven Recent species in the genus, including the present new species. Cyprinotus crenatus (Turner, 1893), C. dentatus (Sharpe, 1910), C. flavescens Brady, 1898, C. inconstans Furtos, 1936, C. newmexicoensis Ferguson, 1967, C. ohanopecoshensis Ferguson, 1966, C. pellucidus (Sharpe, 1897), C. scytodus (Dobbin, 1941) and C. sulphurous Blake, 1931 are here all referred to the genus Heterocypris s. lat. Claus, 1892. Cyprinotus unispinifera Furtos, 1936 is assigned to the genus Cypricercus Sars, 1895. Cyprinotus tenuis Henry, 1923, C. fuscus Henry, 1919 and C. carinatus (King, 1855) are here classified as doubtful species. A checklist of the 14 non-marine ostracods, now including Cyprinotus drubea sp. nov. and Cypris granulata (Daday, 1910), thus far reported from New Caledonia, is provided. Herpetocypris caledonica Méhes, 1939 and H. caledonica var. minor Méhes, 1939 are synonymised with Candonocypris novaezelandiae (Baird, 1843).

Article Reference The Freshwater Information Platform: An online network supporting freshwater biodiversity research and data publishing
Species distribution data are crucial for understanding biodiversity dynamics and the underlying drivers. For freshwaters, which cover only a small proportion of the world's surface, but host a large variety of species, knowledge on species occurrences is extremely important as they are among the most endangered ecosystems globally. However, a huge body of data gathered by scientists and water managers is currently difficult to access: systematic data publishing practices have not been fully adopted yet and data embedded in scientific papers and research project websites are often challenging to extract. At the same time, data and knowledge generated through publically-funded research or monitoring programmes are considered a common good. The Freshwater Information Platform (FIP) aims at pooling freshwater related research information from multiple projects and initiatives to make it easily accessible for scientists, water managers, conservationists and the interested public. The FIP consists of several major components, three of which form its “data publication unit”: The Freshwater Metadatabase (1) is an online tool where data characterising and documenting actual datasets can be entered in a simple way. With one more mouseclick these metadata can then be published as open access articles in the connected Freshwater Metadata Journal. The second part of the unit is the Freshwater Biodiversity Data Portal (2), where we aim to mobilise and publish the connected freshwater biodiversity data (occurrence records) through GBIF (Global Biodiversity Information Facility). The use of collected datasets for large-scale analyses and models is demonstrated in the Global Freshwater Biodiversity Atlas (3) that publishes interactive online maps featuring research results on freshwater biodiversity, threats and conservation priorities. Here, we focus on introducing these components as tools to streamline open access freshwater data publication, arguing it will improve the capacity to protect and manage freshwater biodiversity in the face of global change. We further present linkages to and cooperations with other key initiatives in the field, namely the "Alliance for Freshwater Life" as well as "FreshwaterBON".

Article Reference The Freshwater Information Platform: a global online network providing data, tools and resources for science and policy support
Freshwaters are among the most complex, dynamic, and diverse ecosystems globally. Despite their small share of the earth’s surface (less than 1%) they are home to over 10% of all known animal species. Biodiversity decrease in general and freshwater biodiversity decline in particular have recently received increasing attention, and various policy instruments are now targeting the conservation, protection and enhancement of biodiversity and associated ecosystem services. Surveillance programs as well as a variety of research projects have been producing a tremendous amount of freshwater-related information. Though there have been various attempts to build infrastructures for online collection of such data, tools and reports, they often provide only limited access to resources that can readily be extracted for conducting large scale analyses. Here, we present the Freshwater Information Platform, an open system of relevant freshwater biodiversity-related information. We provide a comprehensive overview of the platform’s core components, highlight their values, present options for their use, and discuss future developments. This is complemented by information on the platform’s current management structure, options for contributing data and research results and an outlook for the future.

Article Reference Unexpected fish diversity gradients in the Amazon basin
Using the most comprehensive fish occurrence database, we evaluated the importance of ecological and historical drivers in diversity patterns of subdrainage basins across the Amazon system. Linear models reveal the influence of climatic conditions, habitat size and sub-basin isolation on species diversity. Unexpectedly, the species richness model also highlighted a negative upriver-downriver gradient, contrary to predictions of increasing richness at more downriver locations along fluvial gradients. This reverse gradient may be linked to the history of the Amazon drainage network, which, after isolation as western and eastern basins throughout the Miocene, only began flowing eastward 1–9 million years (Ma) ago. Our results suggest that the main center of fish diversity was located westward, with fish dispersal progressing eastward after the basins were united and the Amazon River assumed its modern course toward the Atlantic. This dispersal process seems not yet achieved, suggesting a recent formation of the current Amazon system.

Article Reference EJT editorial standard for the semantic enhancement of specimen data in taxonomy literature
This paper describes a set of guidelines for the citation of zoological and botanical specimens in the European Journal of Taxonomy. The guidelines stipulate controlled vocabularies and precise formats for presenting the specimens examined within a taxonomic publication, which allow for the rich data associated with the primary research material to be harvested, distributed and interlinked online via international biodiversity data aggregators. Herein we explain how the EJT editorial standard was defined and how this initiative fits into the journal’s project to semantically enhance its publications using the Plazi TaxPub DTD extension. By establishing a standardised format for the citation of taxonomic specimens, the journal intends to widen the distribution of and improve accessibility to the data it publishes. Authors who conform to these guidelines will benefit from higher visibility and new ways of visualising their work. In a wider context, we hope that other taxonomy journals will adopt this approach to their publications, adapting their working methods to enable domain-specific text mining to take place. If specimen data can be efficiently cited, harvested and linked to wider resources, we propose that there is also the potential to develop alternative metrics for assessing impact and productivity within the natural sciences.

Article Reference The new Southeast Asian genus Cambonilla gen. nov.(Zodariidae, Araneae):‘bis repetita placent’
The new genus Cambonilla Jocqué gen. nov. is described on the base of two species, each known from both sexes. A cladistic analysis based on morphology, showed that the new genus is the sister-group of Heliconilla Dankittipakul, Jocqué & Singtripop, 2012 with which it shares the granulated carapace with branched setae and the marbled ventral abdominal pattern, but differs by the abdominal, tubular sclerotized protrusion around the pedicel in males and the absence of posterior ventral abdominal spines in the female. The type species Cambonilla securicula Jocqué gen. et sp. nov. was found in rainforest along the Mekong River in Cambodia and Laos. The second species Cambonilla symphonia Jocqué & Henrard gen. et sp. nov., provided with conspicuous femoral stridulating organs, was recorded from the same localities but in Cambodia only. An illustrated key to the genera of tropical Asia is presented.

Article Reference Precision mapping of snail habitat provides a powerful indicator of human schistosomiasis transmission
Recently, the World Health Organization recognized that efforts to interrupt schistosomiasis transmission through mass drug administration have been ineffective in some regions; one of their new recommended strategies for global schistosomiasis control emphasizes targeting the freshwater snails that transmit schistosome parasites. We sought to identify robust indicators that would enable precision targeting of these snails. At the site of the world’s largest recorded schistosomiasis epidemic—the Lower Senegal River Basin in Senegal—intensive sampling revealed positive relationships between intermediate host snails (abundance, density, and prevalence) and human urogenital schistosomiasis reinfection (prevalence and intensity in schoolchildren after drug administration). However, we also found that snail distributions were so patchy in space and time that obtaining useful data required effort that exceeds what is feasible in standard monitoring and control campaigns. Instead, we identified several environmental proxies that were more effective than snail variables for predicting human infection: the area covered by suitable snail habitat (i.e., floating, nonemergent vegetation), the percent cover by suitable snail habitat, and size of the water contact area. Unlike snail surveys, which require hundreds of person-hours per site to conduct, habitat coverage and site area can be quickly estimated with drone or satellite imagery. This, in turn, makes possible large-scale, high-resolution estimation of human urogenital schistosomiasis risk to support targeting of both mass drug administration and snail control efforts.
