The results delineate six groups of populations, which are recognised as species. Phoxinus phoxinus is found in eastern France in the lower and middle Rhine and Seine drainages. Phoxinus bigerri occurs in the Adour drainage and populations from the Lake Geneva basin and the upper Rhine drainage are identified as Phoxinus csikii. Phoxinus dragarum, new species, from the Garonne drainage, is distinguished by its unique nuptial colour pattern (green stripe in Z3 reaching up to the anal fin base and Z4 greenish yellow in male; Z4 green-ochre and black line below in Z5 reaching from the pectoral fin bases to the anal fin base in female), and by an incomplete lateral line generally reaching to a point in front of the anal fin base or just shortly beyond the origin of the last anal fin ray. Phoxinus fayollarum, new species, from the Loire drainage, is distinguished by its unique nuptial colour pattern (green bars in Z3 and Z4, Z4 bright yellow, and belly red in male; green stripe in Z3, Z4 yellow-pinkish, and red spots at the pectoral, pelvic and anal fin base in female). Minnows of the Rh{\^o}ne drainage are identified as Phoxinus septimaniae. We consider Pisciculus varius and Phoxynus montanus as nomen oblitum and Phoxinus septimaniae as nomen protectum, and Leuciscus obtusus as incertae sedis within Leuciscidae.}, author = {Denys, Ga{\"e}l and Dettai, Agn{\`e}s and Persat, Henri and Daszkiewicz, Piotr and Hautecoeur, M{\'e}lyne and Philippe Keith} } @proceedings {8401, title = {Upstream as a sanctuary for the French populations of catalan chub Squalius laietanus (Teleostei , Leuciscidae) threatened by the allochtonous European chub S. cephalus}, year = {2020}, abstract = {In the Pyr{\'e}n{\'e}es-Orientales department (France), three Mediterranean catchments (Agly, T{\^e}t and Tech) are subject to high variations in water levels during Cevenol-type events. In order to fight against the effects of these floods, dams and wiers were built along these rivers with consequences on aquatic fauna, eliminating the ecological continuum. The chub Squalius is a potamodromous fish occurring from the salmonids stream to close to the estuaries. Moreover, whereas the European chub S. cephalus was thought to be represented by a single species in France, another species, endemic to Catalonia, was described: the Catalan chub S. laietanus. However, S. cephalus was also introduced in the catchments of this area with possibly threats of hybridization. Samples from eight populations of Squalius spp coming from these rivers were genetically identified using a DNA Barcoding approach with a mitochondrial (COI) and a nuclear (RAG1) markers. Our results confirm the presence of both species in the three drainages as well as their hybridization, threatening S. laietanus by hybridization as in 70\% of Mediterrannean endemic species. There is also a downstream-upstream gradient in the presence of S. cephalus in the T{\^e}t and Tech catchments. S. laietanus seems less impacted by S. cephalus in headwaters than downstream. One of the explanations would be the numerous weirs between these areas. If the negative impacts of the absence of ecological continuum on the ichthyofauna are known and cannot be denied, these weirs might form in this case a barrier against the presence of S. cephalus in headwaters. As a consequence, S. laietanus has been evaluated as EN in the last French UICN Red List published in 2019. While the ecological parameters still need to be examined, our study brings additional information for better suited conservation actions regarding the ecological continuum.}, author = {Rose, Morgane and Dettai, Agn{\`e}s and Lef{\`e}bvre, St{\'e}phane and Blanc, Laurence and Poulet, Nicolas and Baudier, Olivier and Hautecoeur, M{\'e}lyne and Denys, Ga{\"e}l} } @proceedings {6079, title = {Ecoregionalisation and conservation of benthic communities in the French exclusive economic zone of Kerguelen}, volume = {1}, year = {2019}, month = {11/06/2019}, pages = {pp 413}, publisher = {Australian Antarctic Division}, edition = {Australian Antarctic Division, Kingston, Tasmania, Australia}, address = {Kingston, Tasmania, Australia}, abstract = {

The deep-sea benthic ecosystems of the French Kerguelen exclusive economic zone remain poorly understood. To address benthic conservation issues, the authors recently contributed expert knowledge to guide the recent extension of the Marine Reserve of the {\textquoteleft}Terres australes fran{\c c}aises{\textquoteright}. In this new study, we propose a benthic ecoregionalisation of the northern Kerguelen Plateau based on a measurable and repeatable methodology that relies on the generalised dissimilarity modelling technique. Data of macro-epibenthic invertebrate species from the POKER 2 (2010) fish stock assessment survey have been used to compute the models. Our results allow us (i) to characterise and map benthic landscape units based on assemblages of marine invertebrates pooled by taxa and life-history traits, (ii) to highlight the environmental drivers of the spatial distribution of benthic assemblages, (iii) to assess the relevance of the CCAMLR{\textquoteright}s vulnerable marine ecosystems bioindicator taxa, and (iv) to assess the effectiveness of {\textquoteleft}strictly protected areas{\textquoteright} of the new Marine Reserve for the conservation of deep-sea benthic ecosystems.

This integrative taxonomy study of French pikes compares morphological characters and molecular sequence data (mitochondrial COI and nuclear Plagl2 genes). In addition to the expected E.\ lucius, DNA sequences and morphology both support a new species in France, E.\ aquitanicus sp. nov. from the Charente to the Adour drainages. It is characterized by a color pattern of sides with narrow 1{\textendash}1.5-scale-wide oblique vertical bands, conferring it a marbled coat, a snout only 0.9 times larger than the postorbital length, an anal fin basis 1.1{\textendash}1.2 times larger than the caudal peduncle length, 101 to 121 lateral scales, 53 to 57 vertebrae, as well as 24 diagnostic sites in the COI gene and 3 in the Plagl2 gene. Partial COI sequences (131bp) from modern and historical specimens indicate also the presence of E.\ cisalpinus and E.\ lucius during the 19th century in Lake Geneva. Morphological and molecular data points to a possible hybridization between E.\ lucius with both other local pike species, representing a risk for them. Their endangerment status should be evaluated rapidly in order to take conservation measures.
