Excluding Ponto-Caspian species originating in brackish waters and freshwater subterranean taxa, there are 11 formally recognized epigean freshwater species recorded from this country. They belong to 3 genera, each representing a different family: Gammarus (Gammaridae, 8 species or species complexes), Niphargus (Niphargidae, 2 epigean species) and Synurella (Crangonyctidae, one species). Their large-scale distribution patterns nevertheless remain obscure due to insufficient data, consequently limiting biogeographical interpretations. We provide extensive new data with high resolution distribution maps, thus improving the knowledge of the ranges of these taxa. -

A Comprehensive List of the Ants of Romania (Hymenoptera: Formicidae) 1
Myrmecologische Nachrichten 9 65 - 76 Wien, Dezember 2006 A comprehensive list of the ants of Romania (Hymenoptera: Formicidae) 1 Bálint MARKÓ, Botond SIPOS, Sándor CSŐSZ, Klára KISS, István BOROS & László GALLÉ Abstract In the last decades the ant checklists of most Central and Eastern European countries were updated, with the exception of Romania. The last Romanian checklist was published in 1978 and contained only 76 species. The present work lists all species mentioned in publications until 2006. Up to now, altogether 103 valid species were recorded in the Romanian fauna (102 outdoor species), besides these there are eleven species of uncertain occurrence in Romania and two names which cannot be assigned to existing valid species. The comparison of Romanian and other Central and Eastern Euro- pean myrmecofaunas reveals that the Romanian fauna is insufficiently known and that a considerable number of spe- cies (mostly parasitic and Mediterranean) remains to be detected.

The Key Threats to Sturgeons and Measures for Their Protection in the Lower Danube Region
THE KEY THREATS TO STURGEONS AND MEASURES FOR THEIR PROTECTION IN THE LOWER DANUBE REGION MIRJANA LENHARDT* Institute for Biological Research, Serbia IVAN JARIĆ, GORČIN CVIJANOVIĆ AND MARIJA SMEDEREVAC-LALIĆ Center for Multidisciplinary Studies, Serbia Abstract The six native sturgeon species have been commercially harvested in the Danube Basin for more than 2,000 years, with rapid decrease in catch by mid 19th century. Addi- tional negative effect on sturgeon populations in the Danube River was river regulation in Djerdap region, due to navigation in the late 19th century, as well as dam construction in the second half of 20th century that blocked sturgeon spawning migrations. Beside over- fishing and habitat loss, illegal trade, life history characteristics of sturgeon, lack of effective management (due to lack of transboundary cooperation and change in political situa- tion in Lower Danube Region countries) and pollution all pose serious threats on sturgeon populations in Lower Danube Region. International measures established by the Conven- tion on International Trade in Endangered Species (CITES) in late 20th century, listing of beluga (Huso huso) as an endangered species under the U.S. Endangered Species Act, as well as development of Action plan for conservation of sturgeons in the Danube River Basin, had significant impact on activities related to sturgeon protection at beginning of 21st century. These actions were aimed towards diminishment of pressure on natural sturgeon populations and aquaculture development in countries of Lower Danube Region. The main goal of the Action Plan was to raise public awareness and to create a common framework for implementation of urgent measures. -

Brochure: Sturgeon Identification Guide
Andrey Nekrasov © Photo: STURGEON IDENTIFICATION GUIDE Identification of Sturgeon Species This guide was designed to support the identification of sturgeon species that can be found in the Danube and the Black Sea. It describes seven sturgeon species - one of them an exotic species popular in aquaculture - and three hybrids. The guide also offers detailed features that can be used to differentiate between the species. The primary goal of this guide is to help law enforcement officials identify sturgeon species they may encounter through their work. WHAT IS A STURGEON? Sturgeons and paddlefishes, also referred to scientifically as Acipenseriformes, are a group of ancient fish originating more than 200 million years ago. They migrate mostly in order to spawn and live in freshwater, coastal waters and seas of the Northern Hemisphere. According to the IUCN*, 23 of the 27 species are on the brink of extinction, being thus the most critically endangered group of species on Earth. *International Union for Conservation of Nature Sturgeons have quite unique features: Depending on the species, Five rows of bony scutes: Two nostrils on the snout smaller scutes can also be one row along the back, found in between the rows two along both sides, If a fish has only of the larger scutes, behind and two on the belly one nostril, it is the dorsal fin and along the most likely from anal fin, which can be a very aquaculture. important characteristic for differentiation.

Conservation and Sustainable Use of Wild Sturgeon Populations of the NW Black Sea and Lower Danube River in Romania
Conservation and sustainable use of wild sturgeon populations of the NW Black Sea and Lower Danube River in Romania Raluca Elena Rogin Marine Coastal Development Submission date: June 2011 Supervisor: Egil Sakshaug, IBI Norwegian University of Science and Technology Department of Biology Abstract Sturgeons belong to one of the oldest families of bony fish in existence, having their first appearance in the fossil records approximately 200 million years ago. Their natural habitats are found in the subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. In the Romanian waters, five anadromous species of sturgeon, out of the total 25 species known by science, once migrated from the Black Sea into the Danube for spawning: beluga; Huso huso , Russian sturgeon; Acipenser gueldenstaedtii , stellate sturgeon; A. stellatus , ship sturgeon; A. nudiventris and the European Atlantic sturgeon; A. sturio (Knight, 2009). The NW Black Sea and Lower Danube River sturgeons, like many Acipenserids, were seriously affected by the rapid changes brought by human development. Being one of the finest caviar producers in the world they were intensively harvested for many centuries. Heavy uncontrolled fishing and destruction of habitat led to the collapse of most of the Acipenserids and the total disappearance of the European Atlantic sturgeon (A. sturio ) from the NW Black Sea. Worldwide public attention was focused on sturgeon conservation after their listing in the IUCN Red List of Threatened species in 1996. In 1998, after evaluating their abundance in the wild, CITES also decided to strictly regulate the international trade in all Acipenserids. The paper aims to analyze and review conservation measures that were taken locally, nationally and internationally by humans and the effect they had on one of Europe’s only naturally reproducing sturgeon populations. -

The aim of the ICPDR Sturgeon Strategy is to contribute to the survival and recovery of sturgeons in the Danube River Basin by highlighting the challenges currently faced. The scope of the action involves providing an overview of actions and measures considered necessary by sturgeon specialists, in particular from the Danube Sturgeon Task Force 1 working towards securing the survival of sturgeons within the framework of “water competences” of the ICPDR and fostering synergies and cooperation with all national and international players dedicated to sturgeon conservation activities. -

Received: 14 November 2020; Accepted: 14 December 2020; Published: 15 December 2020 Abstract: MicroRNAs play a crucial role in eukaryotic gene regulation. For a long time, only little was known about microRNA-based gene regulatory mechanisms in polyploid animal genomes due to difficulties of polyploid genome assembly. However, in recent years, several polyploid genomes of fish, amphibian, and even invertebrate species have been sequenced and assembled. Here we investigated several key microRNA-associated genes in the recently sequenced sterlet (Acipenser ruthenus) genome, whose lineage has undergone a whole genome duplication around 180 MYA. We show that two paralogs of drosha, dgcr8, xpo1, and xpo5 as well as most ago genes have been retained after the acipenserid-specific whole genome duplication, while ago1 and ago3 genes have lost one paralog.
