“…There are number of studies that have identified and proposed different aquatic invertebrate species as flagship umbrellas as well as bioindicators. For example, Freshwater pearl mussel has been argued to act as an effective flagship umbrella for the conservation of co-occurring biodiversity and an indicator species of healthy river ecosystems (Geist, 2010;Grambow, 2015). In non-permanent aquatic habitats several crayfish species have been proposed as flagship umbrellas and bioindicators, including the Nobel crayfish Astacus astacus (Reynolds and Souty-Grosset, 2011), which belongs to the same genus as the PC crayfish Astacus pachypus.…”

The declining biodiversity has upsetting consequences for social and economic development and represents a major concern for humanity. Legal and political framework plays an important role in biodiversity conservation planning, implementation, and coordination of actions. Legal provisions are complex and operate on different levels of governance (from supranational to national), which means that the status of single species or populations may be governed by a set of interacting or even conflicting regulations, with increasing complexity for species that occur across national borders. Romania (EU member state) and Ukraine (non-EU member state) exemplify neighboring countries with different governance systems, which share the same endemic aquatic communities inhabiting the transitional zones between freshwater and marine ecosystems, known regionally as Pontocaspian (PC) biota. These communities include flagship species such as sturgeons and less-known crustaceans and mollusks and are severely threatened as a result of human activities. We assessed the legal basis for the protection of PC biota in the Danube Delta and the effectiveness of current conservation approaches based on a review of legal documents and literature, expert opinion, and practitioner reflections regarding PC biodiversity conservation. We found that PC invertebrate species are not adequately addressed in the current legal documents and that the surrogate approach (where protection of umbrella species results in protection of background species) does not work as there is little overlap between the habitats of sturgeons and PC invertebrate communities. Furthermore, the habitat definitions currently used in legal documents lack the level of detail needed to protect PC habitats that are characterized by specific salinity (brackish) conditions. We finish by sketching out recommendations toward improved legal and political frameworks for effective and efficient conservation of PC invertebrate biota.

“…Other authors have also emphasized the flagship potential of sturgeons and paddlefish in general (e.g. Cooke et al, 2013;Doukakis et al, 2012;Grambow, 2015), while some species have been indicated explicitly as suitable flagship species, such as lake sturgeon (McDermid, Browne, Chetkiewicz, & Chu, 2015), Chinese sturgeon (A. sinensis;Fu, Wu, Chen, Wu, & Lei, 2003;Kottelat & Whitten, 1996), European sturgeon (Rochard, 2011), and Chinese paddlefish (Mims, 2015). They have also been advocated as flagship species by various organizations, such as the World Wildlife Fund (WWF) and the International Commission for the Protection of the Danube River (ICPDR; Kalinkat et al, 2017).…”

Summary Although sturgeons and paddlefish represent a highly endangered species group, knowledge regarding their ecology, life history and management and restoration measures still reveals substantial gaps and uncertainties. As such, it was hypothesized that the information on overall experiences and perspectives of researchers working in the field would provide a good indication of the state of knowledge, and help identify areas for further investigation. To gain in‐depth insight into their perspectives on a variety of topics related to sturgeon life history, management and conservation, as well as opinions on issues characterized by a lack of data, a worldwide online survey was conducted among scientists specializing in sturgeon and paddlefish research. With a total of 277 respondents, the response rate was good (40.3% of those invited). The survey results indicated a high level of uncertainty with regard to various aspects of sturgeon life history, such as spawning migrations, reproduction and senescence. Responses differed largely with the origin and the research focus of the participants. Agreement on reported extreme dimensions and lifespans of sturgeons varied among species, but the level of agreement was generally higher among those scientists working on the species in question. Responses on major threats varied regionally, with dams and habitat fragmentation recognized as the major threats by researchers from North America, whereas poaching was considered the dominant threat in Europe and Asia. Sturgeon aquaculture was generally considered as having a positive effect on sturgeon protection by reducing the pressure on natural populations. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) was recognized as the most effective instrument in international sturgeon conservation. While sturgeons are generally perceived as flagship species, especially in Europe, participants questioned their potential utilization as umbrella species. Beside providing an insight into the available scientific information and the general level of consensus regarding some of the questions tackled, the results also created a basis for further discussion within the scientific community concerning the validity, relevance, and application of the published information and future research priorities.
