A student from South Pacific University, Rynae Greta Lanyon, having get an IRCP-Tahiti Perles grant, published on the structural diversity of brain organization in coral reef fish

In coral reefs, one of the great mysteries of teleost fish ecology is how larvae locate the relatively rare patches of habitat to which they recruit. The recruitment of fish larvae to a reef, after a pelagic phase lasting between 10 and 120 days, depends strongly on larval ability to swim and detect predators, prey and suitable habitat via sensory cues. However, no information is available about the relationship between brain organization in fish larvae and their sensory and swimming abilities at recruitment. For the first time, we explore the structural diversity of brain organization (comparative sizes of brain subdivisions: telencephalon, mesencephalon, cerebellum, vagal lobe and inferior lobe) among larvae of 25 coral reef fish species. We then investigate links between variation in brain organization and life history traits (swimming ability, pelagic larval duration, social behaviour, diel activity and cue use relying on sensory perception). After accounting for phylogeny with independent contrasts, we found that brain organization co-varied with some life history traits: 1) fish larvae with good swimming ability (> 20cm/s), a long pelagic duration (> 30 days), diurnal activity and strong use of cues relying on sensory perception for detection of recruitment habitat, had a larger cerebellum than other species. 2) Fish larvae with a short pelagic duration (< 30 days) and nocturnal activity had a larger mesencephalon and telencephalon. Lastly, 3) fish larvae exhibiting solitary behaviour during their oceanic phase had larger inferior and vagal lobes. Overall, we hypothesize that a well-developed cerebellum may allow fish larvae to improve their chances of successful recruitment after a long pelagic phase in the ocean. Our study is the first one to bring together quantitative information on brain organization and the relative development of major brain subdivisions across coral reef fish larvae, and more specifically to address the way in which this variation correlates with recruitment process.

In the SPC newsletter, two articles present the regional and international workshops organized by the IRCP in 2013: “Research goals for the new eel network for the South Pacific” by Pierre Sasal et al. (workshop organized in December 2013 at Moorea, French Polynesia) and “International workshop on different survey methods for coral reef fish, including methods based on underwater video” by Gilles Siu and David Lecchini et al.

Private firms could be interested by the eels in the South Pacific

Workshop - tropical eels

A workshop concerning the tropical eels was organized at Moorea by the CRIOBE and IRCP, with a funding from French Embassy in the Pacific (‘Fond Pacifique’). The seminars and field trips allowed to join together the data on biology and ecology of tropical eels in the Pacific, data from Scientifics, private firms, NGO in order to better know the eel stocks. This better knowledge of fish stock would allow the exploitation of tropical eels by some private firms.

Economic Valuation Of Mangrove Ecosystem Services In Vanuatu: Case Studies of Crab Bay (Malekula Is.) And Eratap (Efate Is.)

Executive summary

Objectives and context
This study objective is to produce the economic valuation of mangrove ecosystem services in Vanuatu. It is part of the MESCAL project developed to address the main challenges to mangrove management and conservation. Specifically, the study contributes to the outcome n°1 (National Baseline Information about Climate Change Scenarios, use and values of Mangroves and Associated Ecosystems) as well as to the outcome n°4 (Increased Awareness, Advocacy and Capacity development).
In response to market failures, economic valuation of mangrove ecosystem services (ES) is viewed as a promising approach at different levels. In this study the ES evaluation was undertaken to raise awareness among decision-makers, policy-makers and the public regarding the benefits of the environment for society. Based on the general recognition that “money talks”, its role will be to strengthen the support to environment regulation and resource management actions. At the same time, this study can be part of a monitoring routine to inform management with economic indicators (“we manage better what we can measure”).
