	abstract = {Amphidromous goby fry (post-larvae and young juveniles) are traditionally fished when they arrive in rivers after their larval development at sea. In Reunion Island (Indian Ocean) two species of amphidromous goby are mainly targeted by the fisheries: the endemic\&nbsp;Cotylopus acutipinnis\&nbsp;and the cosmopolitan\&nbsp;Sicyopterus lagocephalus. Despite the lack of quantitative data on these fisheries, their impact on populations\&nbsp;is expected to be important because the catches can represent several tonnes per year. Consequently, fishery regulation changes have been proposed that increase the duration of the existing fisheries closure period of two weeks in March. We developed an approach to identify key periods for fisheries closure, including assessment of the proposed management scenario and several alternative protection scenarios, based on the maximization of fry abundance and on the variability of four life-history traits: (i) fry size and (ii) age at arrival in rivers, (iii) the time the juveniles spend in river before maturation and (iv) their migration behaviour. This approach is in seeking to preserve a high level of phenotypic diversity, which is predicted to promote population resilience. We conducted a multiple-criteria decision analysis to rank 4096 alternatives of fisheries closure periods, ranging from zero to 12 months, based on their propensity to maintain fry abundance and life history trait diversity. Finally, according to the type of fisheries closure period (discontinuous or continuous) and the proportion of annual abundance and variability of life-history traits preserved during the period (50\% or 75\%), we propose four different fisheries closures lasting from six to nine months.},

	abstract = {One of the biggest challenges of the 21st century is to reduce carbon emissions and offshore wind turbines seem to be an efficient solution. However, during the installation phase, high levels of noise are emitted whose impacts remain not well known, particularly on benthic marine invertebrates displaying a bentho-planktonic life-cycle. For one century, larval settlement and subsequent recruitment has been considered as a key topic in ecology as it determines largely population renewal. Whereas several recent studies have shown that trophic pelagic but also natural soundscape cues could trigger bivalve settlement, the role of anthropogenic noise remains poorly documented. Therefore, we conducted experiments to assess potential interacting effects of diet and pile driving or drilling sounds on the great scallop (Pecten maximus) larval settlement. We demonstrate here that pile driving noise stimulates both growth and metamorphosis as well as it increases the total lipid content of competent larvae. Conversely, drilling noise reduces both survival and metamorphosis rates. For the first time, we provide evidence of noise impacts associated to MREs installation on P. maximus larvae and discuss about potential consequences on their recruitment.},

	abstract = {Understanding the population structure of tropical anguillids residing in the Pacific is vital for their conservation management. Here, the population genetic structure of five sympatric freshwater eels (Anguilla marmorata Quoy \&amp; Gaimard, A.\&nbsp;megastoma Kaup, A.\&nbsp;obscura Steindachner, A.\&nbsp;reinhardtii G{\"u}nther and A.\&nbsp;australis Richardson) across 11 western South Pacific (WSP) islands was investigated based on partial nucleotide sequences of the mtDNA control region and the nuclear GTH2b genes of 288 newly collected samples jointly with existing sequences. WSP anguillids are characterised by overall high levels of genetic diversity. Both mtDNA and nuclear sequences provided no evidence for distinct geographic clines or barriers in any of the species across the WSP. The occurrence of admixed individuals between A.\&nbsp;marmorata and A.\&nbsp;megastoma was confirmed, and a new possible occurrence of a further species was revealed (A.\&nbsp;interioris Whitley on Bougainville Island). All species showed evidence for demographic population growth in the Pleistocene, and a subsequent population reduction for A.\&nbsp;megastoma. Common spawning grounds and mixing of larvae by ocean currents could promote the lack of pronounced isolation by distance, a finding that has significant implications for the future management of anguillids in the area.},

	abstract = {<p>Examination of the larval shell (prodissoconch) of molluscs with planktotrophic development can provide valuable information on their planktonic and early benthic life. We examined temporal variability of abundance and size among 11,994 veligers of the blue mussel (<em>Mytilus edulis</em>) in a coastal lagoon during settling periods between 1995 and 2009. Size and date at metamorphosis during the recruitment season were determined for 1,925 postlarvae (shell length, 255{\textendash}900 {\textmu}m) with prodissoconch II (PII) measurements. Emphasizing the recurrence of metamorphosis delay in the field, our study reveals a net increase in mean size at metamorphosis through time, with means for PII size ranging from 255{\textendash}288 {\textmu}m early in summer (after peak spawning events) to 400{\textendash}422 {\textmu}m (PII) during late July to early September. By estimating the {\textquotedblleft}true{\textquotedblright} settlement date using the amount of dissoconch secreted after metamorphosis, such time-series analyses appropriately recapitulated the temporal pattern of mean pediveliger (competent larvae) size in the plankton. Our results demonstrate that greater settlement success rates were related to small size at metamorphosis{\textemdash}in particular, less than 320 {\textmu}m. Seasonal increase in mean PII size occurring during the latter part of the settling period may be explained by competent veligers remaining adrift and delayed metamorphosis as a result of the lack of favorable encounters with a suitable substrate or the absence of specific trophic signals, or cues, required for stimulating settlement, thus forcing larvae to continue planktonic growth. The difference between the smallest and largest means for PII size corresponds to 122 {\textmu}m of larval shell growth, or 47.8\%, potentially representing a 322\% difference in larval body mass at settlement.</p>
