To investigate the implications of their unique life history, we examined the population structure of the amphidromous shrimp Caridina natalensis across its known range in the South Western Indian Ocean. A total of 118 specimens were collected from 7 islands (Mayotte, Mohéli, Mahé, Praslin, Silhouette, Mauritius and Madagascar) and the African mainland (South Africa), and their 16S rRNA and Cox1 mitochondrial genes were sequenced. Our findings reveal significant regional structure among archipelagos, suggesting complex patterns of dispersal involving successive events of extinction-recolonization. By conducting a comparative analysis with six other amphidromous species from the South Western Indian Ocean, based on literature sources, we were able to draw conclusions regarding the amphidromous biogeography of the area. Furthermore, we propose a novel classification of amphidromous species, considering their population structure and life history traits. We defined four categories of increasing dispersal abilities and decreasing genetic population structure: 1. Land-locked species; 2. Species with reduced or facultative amphidromy; 3. Species with common amphidromy; and 4. Super-amphidromous species. Lastly, we identified the Comoros Islands (namely Mayotte and Mohéli) as a critical area for the dispersal of amphidromous species, emphasizing the need for prioritizing conservation efforts in this region. %B Hydrobiologia %8 Jun-26-2023 %G eng %U https://link.springer.com/10.1007/s10750-023-05283-7 %!

It was tested on freshwater pipefish, as external tissue sampling is made difficult by the lack of scales, the lack of pelvic fins, the atrophy of pectoral and anal fins. The internal tissue is detached by scratching the inside of the urogenital papilla with a fine metallic probe. 95% ethanol is injected using a fine syringe, and then sucked back into the syringe with the detached tissue. this protocol has been tested on 6 specimens from 5 species of pipefish. For each specimen DNA was extracted from the internal tissue, a caudal fin clip, and when possible, eggs sampled from the male brooding pouch. Partial Cytochrome c oxydase I (COI) was amplified and sequenced. For each specimen, the 582 bp long sequences obtained from the internal tissue, the fin clip and the eggs were identical. These results validate this non-damaging internal tissue sampling method, which leaves absolutely no trace on the specimen. Although this method was developed on pipefish, it could be applied to other teleostean, even precious museum collection specimens such as type specimens. the aim of this paper, using the example of freshwater pipefish, is to present this method, which aims at preserving precious collection specimens while still valorising them. %B Cybium %V 44 %P 73-79 %G eng %N 1 %R https://doi.org/10.26028/cybium/2020-441-010 %0 Journal Article %J Cybium %D 2020 %T Objective record of Epinephelus marginatus (Serranidae: Epinephelinae) from the Sultanate of Oman (Arabian Sea) %A Bearez, Philippe %A Marion Mennesson %A Pellé, E %B Cybium %V 44 %P 251-254 %G eng %N 3 %0 Journal Article %J Cybium %D 2020 %T Review of Giuris (Teleostei: Eleotridae) from Indo-Pacific islands, with description of three new species %A Philippe Keith %A Marion Mennesson %B Cybium %V 44 %P 331-349 %G eng %N 4 %0 Journal Article %J Zoologica Scripta %D 2019 %T Evolutionary aspects of cephalic sensory papillae of the Indo‐ Pacific species of Eleotris (Teleostei: Eleotridae) %A Marion Mennesson %A Maeda, Ken %A Philippe Keith %X

 Eleotris species (Teleostei: Eleotridae) are one of the most common fish in Indo‐Pacific estuaries and insular freshwater streams. In these rivers, they are a sit‐andwaitpredator. They have an amphidromous life cycle,  that is adults grow, feed and reproduce in rivers, while larvae have a marine dispersal phase. Larvae recruit back to rivers and settle in stream habitats. Primary characters used to determine  Eleotris species are the presence and the disposition of cephalic sensory papillae rows on the operculum and under the eyes as well as scale row numbers. The morphology of these cephalic sensory papillae is of particular importance in this predatory genus as it is generally correlated in fish to predation and feeding. In this paper, we have established a molecular phylogeny of the genus based on the 12 mitochondrial protein‐ coding genes to discuss the relationship between Indo‐Pacific  Eleotris species. There is a well‐supported dichotomy in the molecular phylogeny, and this separation into two main clades is also morphologically visible, as it reveals a difference in the arrangement of cephalic sensory papillae. Indeed, the phylogeny distinguishes the species with the “open” pattern of the operculum sensory papillae and the species with the “closed” one. This phylogeny thus reflects the morphology of the opercular papillae. The evolution of this character is discussed in terms of the adaptation of the Eleotris genus to life in tropical insular river systems.

 Indo-Pacific insular freshwater systems are mainly dominated by amphidromous species. Eleotris fusca  is a widespread one, its life cycle is characterised by a marine pelagic larval phase allowing the species to disperse in the ocean and then to recruit to remote island rivers. In the present study, the population structure of E. fusca  over its Indo-Pacific distribution range (Western Indian Ocean to French Polynesia, Pacific Ocean) was evaluated. We analysed a section of mitochondrial COI  of 557 individuals sampled from 28 islands to visualise the population structure. Haplotypes diversity (Hd) was between 0.458 and 1 and, nucleotide diversity (π) was between 0.001 and 0.02. Two distinct genetic groups appeared, one in the Indian Ocean and the other in the Pacific Ocean (FST  mean = 0.901; 5.2% average divergence). Given these results, complete mitogenomes (mtDNA) were sequenced and combined with the nuclear Rhodopsin (Rh) gene for a subset of individuals. The two phylogenetic trees based on each analysis showed the same genetic pattern: two different groups belonging to the Indian and the Pacific oceans (6.6 and 1.6% of divergence for mtDNA and Rh gene respectively), which supported species level differentiation. These analyses revealed the presence of two sister species confounded until present under the name of Eleotris fusca. One of them is cryptic and endemic of the Indian Ocean and the other one is the true E. fusca, which keeps, nevertheless, its status of widespread species.

The observation of the cephalic free neuromast pattern of the genus Eleotris allows to classify the specimens in different groups of species but, as diagnostic characters without overlap are scarce, the morphological identification of the species is difficult. However, genetic analyses, particularly with barcoding (COI), facilitate the discrimination between species. In a recent study on the phylogeography of Eleotris fusca Bloch & Schneider, 1801 in the Indo-Pacific area, two species have been revealed although they present the same cephalic free neuromast pattern. The first one included specimens mainly from the Pacific Ocean and the second one, specimens from the Indian Ocean. They are separated with a mean pairwise divergence of 5.6% and present 32 diagnostic nucleotide substitutions in the 585 bp of COI sequenced. After the examination of all the available types of the synonym of E. fusca from the Indian Ocean, we revalidated the name of Eleotris klunzingerii Pfeffer, 1893.
