Considering multiple-species attributes to understand better the effects of successive changes in protection status on a coral reef fish assemblage ArchiMer
Preuss, Bastien; Pelletier, Dominique; Wantiez, Laurent; Letourneur, Yves; Sarramegna, Sebastien; Kulbicki, Michel; Galzin, Rene; Ferraris, Jocelyne.
The response of fish assemblages to changes in protection status is a major issue for both biodiversity conservation and fishery management. In New Caledonia, the Abore reef marine reserve harbours more than 500 fish species, and has been subjected to changes in protection status since 1988. The present study investigates the impact of these changes on a wide subset of species (213), based on underwater visual counts collected before the opening and after the closure to fishing of this marine protected area (MPA). We analysed the spatial and temporal variability in fish assemblage attributable to protection status, explicitly considering habitat. To understand the successive responses of fish assemblage to fishing and protection, the assessment models...

Distribution of Siluriformes in a river under the influence of a small hydroelectric power plant of the Paraná River Basin, Brazil Iheringia, Sér. Zool.
Garcia,Thiago D.; Ota,Renata R.; Ferreira,Dhiego G.; Nascimento,Raul H. C.; Galindo,Bruno A.; Pereira,Larissa S.; Zanatta,Augusto S..
ABSTRACT When a river is dammed, impacts differ according to distance from the dam under consideration, and sites closer to the dam are more affected than distant ones. Damming a river changes the flow and landscape characteristics, which, in turn, change the hydrological, limnological and ecological dynamics, such as biological production, species distribution, and ecosystem structuring, functioning and services. This study evaluates the distribution pattern of the Siluriformes (catfish) fish species near a small hydroelectric power plant in the Jaguariaíva River, considering three distinct distances from the dam: upstream region, reservoir and downstream region. Samples were taken with gillnets between March 2013 and December 2014. The abundance and...

Do we protect biological originality in protected areas? A new index and an application to the Bonifacio Strait Natural Reserve ArchiMer
Mouillot, D; Culioli, J; Pelletier, Dominique; Tomasini, J.
Changes in biodiversity may disrupt the ecological functions performed by species assemblages. Hence, we urgently need to examine the implications of biodiversity loss not only in terms of species conservation but also in terms of sustainability of ecosystem services. The ability of protected areas to maintain local species richness has been clearly demonstrated. However, preserving goods and services provided by ecosystems requires not only the conservation of species richness but also the conservation of the most 'original' species, i.e. the ones with the highest average rarity of their attributes which are likely to perform some unique functions in ecosystems. We proposed a new conservation of biological originality (CBO) index as well as associated...

Evaluation de l’état de santé des habitats et peuplements de poissons de la zone de Voh-Koné-Pouembout, Campagnes de stations vidéo rotatives STAVIRO 2007-2013 ArchiMer
Giraud-carrier, Charlotte; Pelletier, Dominique.
• Conducted within the AMBIO project, this work deals with coral reef fish communities and associated habitats, in the New Caledonian lagoons. It aims at assessing the status and trends of habitats and mobile macrofauna in the Voh-Kone-Pouembout lagoon, in the light of demographic and industrial developments and accounting for the existing customary reserve of Oundjo. • It relies on 280 stations collected in 2007 and 2013 using the remote unbaited underwater video STAVIRO rotating technique, which were analysed to characterize habitat, fish assemblages, turtles and sea snakes, from a list of 490 species (AMBIO/A/1). • 143 species (including one turtle species and one sea snake species), belonging to 23 families were observed. The most frequent and abundant...

Ichthyofauna of the inner shelf of Paraná, Brazil: checklist, geographic distribution, economic importance and conservation status Biota Neotropica
Spier,Daphne; Gerum,Humberto Luiz Nadolny; Bornatowski,Hugo; Contente,Riguel; Mattos,Natalia A S; Vilar,Ciro C; Spach,Henry Louis.
Abstract Comprehensive species checklists are essential to effectively implementing preservation and recovery measures, and should assess conservation status, vulnerability degree and anthropogenic threats. This checklist was compiled from fish species recorded in surveys conducted over the last 30 years in the shallow inner continental shelf in the State of Paraná, Brazil. Information on biogeography, conservation status, economic importance and degree of species’ vulnerability are provided. A total of 272 fish species were recorded, spanning 25 orders and 88 families. The most speciose family was Sciaenidae (25 species), followed by Carangidae (23), Engraulidae (10), Carcharhinidae (9), Epinephelidae (9) and Paralichthyidae (9). Most species occurring in...

Stability of spatial structures of demersal assemblages: a multitable approach ArchiMer
Gaertner, Jean-claude; Chessel, Daniel; Bertrand, Jacques.
The present work is based on a set of bottom trawl surveys performed in the Gulf of Lions between 1983 and 1992. A new method which couples the STATIS multitable approach with the logic of correspondence analysis (CoA) is proposed to study the stability of spatial organization of demersal assemblages in terms of species composition. This CoA version of STATIS has provided a clear representation of the stable part of the spatial structure of the assemblages. In addition, it gave an insight into the interannual variations of the distribution of each population around the reference structure. Our results showed that the demersal assemblages of the Gulf of Lions exhibited strong spatial structuring, mainly orientated along a bathymetric gradient. This gradient...

The demersal fish assemblage of the coastal area adjacent to the Tagus estuary (Portugal): relationships with environmental conditions ArchiMer
Prista, N; Vasconcelos, Rp; Costa, Mj; Cabral, H.
The subtidal fish assemblage of Tagus estuary coastal area was sampled in order to infer about its relationship to environmental conditions and its possible nursery function for marine species. Fish sampling took place between May 2001 and February 2002 with an otter trawl. In addition to fish sampling, a physical, chemical and biological characterization of the water column and bottom sediment was performed. Density and biomass were determined and ecological and feeding guilds assigned to each fish species. Correspondence analysis (CA) was used to determine the spatio-temporal structure of the assemblage and its correlation to environmental variables. A total of 36 fish species were identified. The fish assemblage was dominated by few species, both in...

Use of mangrove habitat for reproductive activity by the fish assemblage in the Guaratuba Bay, Brazil ArchiMer
Chaves, P; Bouchereau, Jl.
The role played by a southwestern Atlantic mangrove in the breeding activity of estuarine fishes was evaluated. This fish assemblage represented 85 % of the total catches of the experimental fishery surveyed between 1993 and 1997. To evaluate the maturation and spawning processes, qualitative (macroscopic stages of maturation) and quantitative (gonadosomatic index) attributes were considered which were combined in a reproductive activity index. Four types of occupation were found in the mangrove, according to the reproductive patterns presented by each species. It was estimated that the Guaratuba mangrove is used as a spawning site - either regularly or occasionally - by about 40 % of the species, that make up 41 % to 46 % of the total abundance of this...
