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, Moh{\'e}li, Mah{\'e}, 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 Moh{\'e}li) as a critical area for the dispersal of amphidromous species, emphasizing the need for prioritizing conservation efforts in this region.}, issn = {0018-8158}, doi = {10.1007/s10750-023-05283-7}, url = {https://link.springer.com/10.1007/s10750-023-05283-7}, author = {de Mazancourt, Valentin and Ahmed Abdou and Castelin, Magalie and Ellien, C{\'e}line and Clara Lord and Marion Mennesson and Renneville, Cl{\'e}mentine and Marquet, G{\'e}rard and Philippe Keith} } @article {9301, title = {Why several when one can unite them all?

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.

Sicydiinae gobies have an amphidromous life cycle. Adults grow, feed, and reproduce in rivers, while larvae have a marine dispersal phase. Larvae recruit back to rivers and settle in upstream habitats. Within the Sicydiinae subfamily, the\ Sicyopterus genus, one of the most diverse (24 species), is distributed in the tropical islands of the Indo-Pacific. One of the characters used to determine Sicyopterus species is the upper lip morphology, which can be either smooth, crenulated, or with papillae, and with (2 or 3) or without clefts. The mouth is used as a secondary locomotor organ along with the pelvic sucker. It is thus strongly related to the climbing ability of species and is of major importance for the upstream migration and the colonization of insular freshwater systems. The mouth also has an important role in the feeding mechanism of these herbivorous species. In this paper, we have established a molecular phylogeny of the genus based on the 13 mitochondrial protein-coding genes to discuss the relationship between 18 Sicyopterus species. There is a well-supported dichotomy in the molecular phylogeny of the Sicyopterus genus and this separation into two clades is also morphologically visible, with the distinction of species with three clefts and species with 0 or 2 clefts on the upper lip. The mouth morphology can thus be separated with regard to the molecular phylogeny obtained. The evolution of the mouth morphology is discussed in terms of the adaptation of the Sicyopterus genus to settlement and life in tropical insular river systems.

Concerning N. canalis, western Pacific and central Pacific populations are genetically structured, without shared haplotypes. The Coral Triangle appears to have played a filtering barrier role for N. stumpffi, whose presence in both oceans could be explained by the flow of the south-equatorial current. A barrier to the dispersal of N. canalis between the western and the central Pacific may also exist.

Eight taxa belonging to five families were considered as significant diagnostic species of digestive tracts from fish collected upstream (Achnanthidium subhudsonis, Achnanthes rupestoides, Diadesmis contenta, Diadesmis sp., Eolimna sp., Navicula (dicta) seminulum, Navicula difficillima and Nupela sp.), and five taxa belonging to three families were considered as significant diagnostic species for fish collected downstream (Gomphonema parvulum, Navicula arvensis, Navicula cruxmeridionalis, Nitzschia frustulum and Navicula incarum).

rivers, their biological cycle remain poorly known. For the first time, the otolith elemental composition and microstructure
of two ancestral gobioids, Rhyacichthys guilberti and Protogobius attiti, were investigated to describe their biological
cycle and pelagic larval duration (PLD). The otolith analysis using a femtosecond laser ablation coupled to an inductively
coupled plasma{\textendash}mass spectrometer (fs-LA-ICP-MS) revealed an amphidromous life history for R. guilberti and it
suggested a progressive habitat shift from a marine habitat to a freshwater environment for P. attiti. For the first time, an
endemic species, P. attiti, showed longer and more variable PLD (55.213.5 days) than did a widespread one
(R. guilberti: ,30 days). These results need to be confirmed by analysing more samples but suggest that factors other
than the PLD control endemism and dispersal processes. In association with this first description of the biological cycle for
both species, such an approach is a prerequisite for the management and conservation of both patrimonial species.
Since 1861, freshwater fishes have been studied at different periods in New Caledonia. The first list was published in 1915, but the
major inventories were done between 1998 and 2003. These inventories allowed the discovery of many new species and the publication,
in 2003, of the Atlas of Freshwater fish and crustaceans of New Caledonia, which listed 64 freshwater fish species. Between 2004
and 2010, additional specific surveys were conducted by the MNHN and 9 species were added. Among them, 3 were new for science.
Gobiidae family represents 30\% of the freshwater fishes of New Caledonia. This high percentage is explained by their particular life
cycle adapted to insular systems.
The Sicydiinae subfamily (Teleostei: Gobioidei) is the biggest contributor to the diversity of fish communities in river systems of tropical islands. These species are found in the Indo-Pacific area, the Caribbean region and West Africa. They spawn in freshwater, their planktotrophic larvae drift downstream to the sea where they develop, before returning to the rivers to grow and reproduce. Hence, they are called amphidromous. Their phylogeny has been explored using a total of 3545 sites from 5 molecular markers (mitochondrial DNA: 16S rDNA, cytochrome oxidase I, cytochrome b; nuclear DNA: rhodopsin gene and a nuclear marker specially developed for this study, the interferon regulatory factor 2 binding protein 1-IRF2PB1). Sequences were obtained for 59 Sicydiinae specimens of 9 known genera. The Bayesian and maximum likelihood analyses support the monophyly of the subfamily as well as the monophylyof all genera except Sicydium, which is paraphyletic. Five major clades were identified within this subfamily. One clade contained the genus Stiphodon. Another clade contained Sicyopterus, Sicydium and Parasicydium with Sicyopterus as sister genus of Sicydium. The non-monophyly of Sicydium subclade, because it includes the monotypic genus Parasicydium, challenged the validity of Parasicydium genus. Ancestral area reconstruction showed that the subfamily emerged in the Central West Pacific region implying that previous hypotheses proposing a dispersal route for Sicydiinae into the Atlantic Ocean are unsupported by the present analysis. Our results suggest that the hypotheses for the dispersal route of the genus Sicydium should be reconsidered.

specific body colour in males.
Amphidromy is a distinctive form of
diadromy, but differences in the life histories of
tropical and temperate amphidromous fishes suggest
that there are two types of freshwater amphidromy.
The life histories of Sicydiinae gobies, ayu (Plecoglossus
altivelis), Japanese sculpins (Cottus) and galaxiids
(Galaxiidae), suggest that the Sicydiinae are
representatives of tropical freshwater amphidromy,
whereas ayu, sculpins and galaxiids are representatives
of temperate freshwater amphidromy. The Sicydiine
larval stage may be required to occur in the
ocean for all species, but ayu, sculpins and galaxiids
have landlocked or fluvial forms with larvae that do
not need to enter the ocean for larval feeding and
growth. This suggests that Sicydiine larvae have a high
oceanic dependency whereas ayu, sculpins and galaxiid
larvae have a low oceanic dependency. Freshwater
amphidromous fish in tropical and temperate zones
appear to have developed two different strategies in
the evolution of their life histories. It is likely that the
evolutionary direction of the larval stage of tropical
amphidromy is to remain in the sea and that of
temperate amphidromy is towards having the ability to
remain in freshwater if needed. Tropical and temperate
amphidromy appear to be biologically informative
categories and evaluations of this hypothesis will
facilitate better understanding of the various forms of
amphidromy in the future.
