Au cours de cette dernière décennie, l’essor des approches d’ADN environnemental (ADNe), qui se basent sur l’analyse ADN d’échantillons environnementaux, a considérablement bouleversé notre capacité à caractériser la biodiversité des milieux. Cependant ces approches innovantes nécessitent un travail indispensable de recherche et développement avant leurs mises en application. Ainsi, ce projet avait pour premier objectif d’être une preuve de concept de l’utilisation de l’ADNe pour la détection …

Analysis of the diet of the long-snouted seahorseHippocampus guttulatusby 18SrDNA amplification of prey in faeces

Aquaculture Nutrition (2014)

Emmanuel Corse Sonia Valladares Miquel Planas Alexandro Chamorro José Pintado

Breeding in captivity for research or exhibition (e.g. in aquaria) can replace the capture of wild specimens of endangered species and allow controlled reinforcement of wild populations. With this aim, diet analysis and establishing the adequate prey are determinant factors for breeding success. However, non-invasive approaches such as faecal DNA analysis are advisable for analysing the diet of these species. Therefore, the aim of the present study was to demonstrate the usefulness of faecal DNA analysis by specific PCR amplification of prey DNA for assessing the diet of the seahorse Hippocampus guttulatus. In a comparison of the suitability of different genes (COI, 18SrRNA and 28SrRNA), 18SrRNA was found to be the most suitable for designing specific primers for the prey types fed to seahorses (Artemia, Palaemonetes and Mysidae). The technique was assessed in feeding experiments in which prey ingestion was recorded daily, and faeces were collected for DNA extraction and presence/absence PCR analysis. Amplification of the prey DNA in faeces was consistent with the sequence of prey supplied (prey eaten the day before was always detected). Differences in the time between feeding and detection in faeces suggested prey-specific gut passage times, which were shorter for Palaemonetes than for Mysidae. This fact highlights the importance of feeding trials to avoid overestimating the consumption of prey with long gut retention when PCR-based methods are used. This molecular technique is thus applicable for studying the feeding behaviour of captive seahorses and could be adapted for use in other marine species.

Trade-off between morphological convergence and opportunistic diet behavior in fish hybrid zone

Frontiers in Zoology (2009)

Emmanuel Corse Caroline Costedoat Nicolas Pech Rémi Chappaz Jonathan Grey

The invasive Chondrostoma nasus nasus has colonized part of the distribution area of the protected endemic species Chondrostoma toxostoma toxostoma. This hybrid zone is a complex system where multiple effects such as inter-species competition, bi-directional introgression, strong environmental pressure and so on are combined. Why do sympatric Chondrostoma fish present a unidirectional change in body shape? Is this the result of inter-species interactions and/or a response to environmental effects or the result of trade-offs? Studies focusing on the understanding of a trade-off between multiple parameters are still rare. Although this has previously been done for Cichlid species flock and for Darwin finches, where mouth or beak morphology were coupled to diet and genetic identification, no similar studies have been done for a fish hybrid zone in a river. We tested the correlation between morphology (body and mouth morphology), diet (stable carbon and nitrogen isotopes) and genomic combinations in different allopatric and sympatric populations for a global data set of 1330 specimens. To separate the species interaction effect from the environmental effect in sympatry, we distinguished two data sets: the first one was obtained from a highly regulated part of the river and the second was obtained from specimens coming from the less regulated part.The distribution of the hybrid combinations was different in the two part of the sympatric zone, whereas all the specimens presented similar overall changes in body shape and in mouth morphology. Sympatric specimens were also characterized by a larger diet behavior variance than reference populations, characteristic of an opportunistic diet. No correlation was established between the body shape (or mouth deformation) and the stable isotope signature.The Durance River is an untamed Mediterranean river despite the presence of numerous dams that split the river from upstream to downstream. The sympatric effect on morphology and the large diet behavior range can be explained by a tendency toward an opportunistic behavior of the sympatric specimens. Indeed, the similar response of the two species and their hybrids implied an adaptation that could be defined as an alternative trade-off that underline the importance of epigenetics mechanisms for potential success in a novel environment.

Le "barcoding alimentaire" : développement d'un nouvel outil d'écologie moléculaire pour les milieux d'eau douce : exemple au travers de l'étude de la zone hybride Durance entre les deux chondrostomes français

Emmanuel Corse

Le principal objet de cette these a ete d'etudier les regimes alimentaires des chondrostomes dans la Durance et de les comparer a d'autres populations evoluant dans des rivieres non amenagees. Pour cela nous avons echantillone des populations provenant de zones allopatriques nous permettant de definir des comportements alimentaires de reference. Afin de dissocier l'effet de l'amenagement de la riviere de l'effet sympatrie dans la zone Durance, nous avons echantillone une seconde zone hybride consideree comme faiblement amenagee, l'Ardeche. L'acquisition d'une information fine de la nature des proies ingerees etant complexe a partir des techniques non invasives traditionnellement utilisees (isotopes stables), nous avons developpe une methode d'ecologie moleculaire non invasive, basee sur la determination de l'ADN present dans les excrements du predateur. Cette methode repose sur des PCR specifiques (reaction de polymerisation en chaine) permettant de detecter 34 clades a hautes informations ecologiques (Clade Ecologique). . Les analyses des resultats nous ont permis de valider le et ont montre que l'amenagement de la Durance affectait les populations de chondrostomes selon plusieurs modalites d'actions. Les resultats ont montre egalement que le Cnn etait plus sensible par l'amenagement de la riviere que le Ctt. A l'issue de ce travail, nous proposons donc que le Cnn soit considere comme une espece sentinelle en vue des suivis de l'impact du debit regule sur les communautes biologiques en Durance. En outre, cette these a permis le developpement d'une methode non invasive en ecologie. Elaboree dans le but d'optimiser son accessibilite autant financiere que technique tout en ayant permis de definir finement le comportement alimentaire des chondrostomes a travers plusieurs zones d'etudes, le barcoding alimentaire apparait comme une methode tres prometteuse en ecologie des eaux douces.

Diet Metabarcoding Reveals Extensive Dietary Overlap between Two Benthic Stream Fishes (Zingel asper and Cottus gobio) and Provides Insights into Their Coexistence

Diversity (2022)

Kurt Villsen Emmanuel Corse Gaït Archambaud‐Suard Kévin Héran Emese Meglécz

Niche partitioning studies are essential to understand the mechanisms that allow ecologically similar species to coexist. The Rhone streber (Zingel asper) and the European bullhead (Cottus gobio) are both benthic riverine fishes that consume macroinvertebrates. Both species are protected under European legislature. We focused on trophic niche partitioning between these species, as sufficient access to trophic resources is an important requirement for long-term coexistence. We used a combination of faeces metabarcoding dietary data and prey community data to evaluate dietary overlap, trophic niche variation and dietary preferences. Sampling was performed in three sites along the Durance River (France). Both species consumed a wide range of macroinvertebrates but neither C. gobio nor Z. asper selected the most abundant taxa (chironomids and simuliids). Both species selected larger mayfly (Baetis and Ecdyonurus) and caddisfly (Hydropsyche) taxa. Dietary overlap was generally high but declined when large mayflies were rare. Contrasting secondary prey preferences and trophic niche variation may allow these species to exploit the same preferred mayflies in periods of abundance and to avoid competition during resource scarcity. We propose that dietary partitioning may support the coexistence of these two ecologically similar, benthic predators.

Correction: Phylogenetic Analysis of Thecosomata Blainville, 1824 (Holoplanktonic Opisthobranchia) Using Morphological and Molecular Data

PLoS ONE (2013)

Emmanuel Corse Jeannine Rampal Corinne Cuoc Nicolas Pech Yannick Pérez

Thecosomata is a marine zooplankton group, which played an important role in the carbonate cycle in oceans due to their shell composition.So far, there is important discrepancy between the previous morphological-based taxonomies, and subsequently the evolutionary history of Thecosomata.In this study, the remarkable planktonic sampling of TARA Oceans expedition associated with a set of various other missions allowed us to assess the phylogenetic relationships of Thecosomata using morphological and molecular data (28 S and COI genes).The two gene trees showed incongruities (e.g.Hyalocylis, Cavolinia), and high congruence between morphological and 28S trees (e.g.monophyly of Euthecosomata).The monophyly of straight shell species led us to reviving the Orthoconcha, and the split of Limacinidae led us to the revival of Embolus inflata replacing Limacina inflata.The results also jeopardized the Euthecosomata families that are based on plesiomorphic character state as in the case for Creseidae which was not a monophyletic group.Divergence times were also estimated, and suggested that the evolutionary history of Thecosomata was characterized by four major diversifying events.By bringing the knowledge of palaeontology, we propose a new evolutionary scenario for which macro-evolution implying morphological innovations were rhythmed by climatic changes and associated species turn-over that spread from the Eocene to Miocene, and were shaped principally by predation and shell buoyancy.

A PCR‐based method for diet analysis in freshwater organisms using 18S rDNA barcoding on faeces

Molecular Ecology Resources (2009)

Emmanuel Corse Caroline Costedoat Rémi Chappaz Nicolas Pech Jean‐François Martin

The development of DNA barcoding from faeces represents a promising method for animal diet analysis. However, current studies mainly rely on prior knowledge of prey diversity for a specific predator rather than on a range of its potential prey species. Considering that the feeding behaviour of teleosts may evolve with their environment, it could prove difficult to establish an exhaustive listing of their prey. In this article, we extend the DNA barcoding approach to diet analysis to allow the inclusion of a wide taxonomic range of potential prey items. Thirty-four ecological clade-specific primer sets were designed to cover a large proportion of prey species found in European river ecosystems. Selected primers sets were tested on isolated animal, algal or plant tissues and thereafter on fish faeces using nested PCR to increase DNA detection sensitivity. The PCR products were sequenced and analysed to confirm the identity of the taxa and to validate the method. The methodology developed here was applied to a diet analysis of three freshwater cyprinid species that are assumed to have similar feeding behaviour [Chondrostoma toxostoma toxostoma (Vallot 1837), Chondrostoma nasus nasus (Linnaeus, 1758) and Barbus barbus, (Linneaus 1758)]. These three species were sampled in four different hydrographic basins. Principal Component Analysis based on prey proportions identified distinct perilithon grazer and benthophagous behaviours. Furthermore, our results were consistent with the available literature on feeding behaviour in these fish. The simplicity of the PCR-based method and its potential generalization to other freshwater organisms may open new perspectives in food web ecology.
