Post-doc position at the CRIOBE available

POSITION AVAILABLE
Postdoctoral Research Fellowship
Metabarcoding, Trophic ecology

Duration: 24 Months
The post-doctoral Position will be based at the CRIOBE in the core laboratory on the University of Perpignan Campus (France). Some field trips are planned in French Polynesia. The post-doc will work mainly with Valeriano Parravicini (EPHE-CRIOBE), Serge Planes (CNRS-CRIOBE).

KEY REQUIREMENTS & QUALIFICATIONS
The ideal candidate should demonstrate a background in the employment of metabarcoding from next generation sequencing and experience in the analysis of complex ecological networks. The candidate will be in charge of developing analysis of the trophic niche of reef fish species employing a mixed approach based primarily on DNA metabarcoding of gut and intestinal contents, but also on stable isotopes analysis. The overall goal is to reconstruct the trophic interactions among species based on the identification of exact food consumption. Metabarcoding will mix plants (algae) and animals survey to evaluate the complexity of the diets and introduce the level of admixture on the species diets. The successful candidate will work within the frame of two larger and already funded projects in collaboration with several other international leaders in coral reef ecology.

GLOBAL PROJECT CONTEXT AND OBJECTIVES
Trophic interactions among species provide the basis of ecological and evolutionary dynamics as all species have to acquire the resources necessary to survive and reproduce. These constraints tend to organize biodiversity into complex food-webs where species interact directly, via the classic resource-consumer interaction, or indirectly via multiple resource-consumer interactions linked to one another. Therefore, the topology of food-webs determines synergies, competition and antagonism among species, mediates the effects of external disturbances and is a key property of ecosystems. However, the empirical characterization of trophic networks is generally limited to simplified architectures (e.g. bi-trophic predator-prey relationships, plant-pollinator and host-parasite interactions). Detailed information on food-web architecture for coral reefs relies mainly on data from the Caribbean, Cuba and simplified Pacific food-webs. These architectures are based mainly on gut content analysis, literature or expert opinion and their level of detail is limited to broad trophic guilds (e.g. herbivores, detritivores, invertebrate feeders). This raw resolution impairs our ability to understand the complexity of coral reefs and to evaluate the disturbance potential to propagate through the interaction network. The main goal of this project is to combine metabarcoding analysis based on the existing global DNA-barcode library (cf. BIOCODE project) and stable isotopes analysis to assess reef fishes dietary preferences in the Insular Pacific.

HOW TO APPLY
Interested applicants should send a cover letter, a statement of research goals and a CV to valeriano.parravicini@gmail.com. Applicants will receive an e-mail confirming their application has been received.

CLOSING DATE
All applications should be submitted by 30 September 2017. However, until the position is filled, we will continue to accept application materials. The position aims to start early 2018 at the latest.

Consistency in the supply of larval fishes among coral reefs in French Polynesia – PlosONE publication

Besson M, Gache C, Brooker RM, Moussa RM, Waqalevu VP, LeRohellec M, et al. (2017) Consistency in the supply of larval fishes among coral reefs in French Polynesia. PLoS ONE 12(6): e0178795

For marine fishes with a bipartite life cycle, pelagic larval dispersal can shape the distribution, connectivity, composition and resilience of adult populations. Numerous studies of larval dispersal, and associated settlement and recruitment processes, have examined the relationship between population connectivity and oceanographic features. However, relatively little is known about spatial and temporal variation in the abundance of larvae settling among different reefs and the extent to which the species assemblage of larvae settling at one location is reflective of the assemblage in neighbouring areas. Here, using crest nets, which provide a non-selective measure of the total abundance and assemblage of larvae settling to a reef (i.e. larval supply), we collected larval coral reef fishes at five locations surrounding two spatially disparate French Polynesian islands: Moorea and Nengo-Nengo. Overall, larval settlement patterns were correlated with the lunar cycle, with larval abundance peaking during the new moon. Although there were some spatial differences in larval supply among the five monitored sites, settlement patterns were largely consistent, even at the species level, irrespective of factors such as coastline orientation or distance between sites. This study provides further insights into the mechanisms driving patterns of dispersal and settlement of larval fishes over large spatial scales.

Pacific Voices for a Global Ocean Challenge

The Oceanographic schooner ‘’TARA’’ will berth in Suva as part of its two-year environmental survey across the Pacific Ocean. The French Facility for Global Environment (FFEM) and the Embassy of France along with the Government of Fiji and the University of the South Pacific are organizing a SDG-14 conference in order to elaborate the regional Pacific message and raise awareness on the alarming state of our ocean.

During the first session, stakeholders will interact with the public to discuss sustainable policies and their implementation. In the second session, the conference will present successful examples of sustainable marine resources management projects within the Pacific Region. The last session will bring the scientists to present their latest results and try to understand how climate change may change the Pacific Way of Life forever.

The conference is supported by the French Facility for Global Environment (FFEM) and organized by the Embassy of France in Fiji in partnership with the University of the South Pacific (USP) and with the support of the Government of Fiji.

The conference is hosted by USP at the ICT Auditorium (Japanese ICT Centre).

The “Pacific Voices for a Global Ocean Challenge” Conference aims to invite all regional organisations and partners to contribute and make suggestions for a greater change. The Conference is an external side event to the UN Ocean Conference in New York.
