Small-scale connectivity of coralligenous habitats: insights from a modelling approach within a semi-opened Mediterranean bay
Provedor de dados: 5
Autores: Rossi, Vincent; Lo, Madiop; Legrand, Terence; Ser-giacomi, Enrico; De Jode, Aurélien; Thierry De Ville D’avray, Laure; Pairaud, Ivane; Faure, Vincent; Fraysse, Marion; Pinazo, Christel; Chenuil, Anne.
Habitat connectivity is central to several key evolutionary and ecological processes, having implications for the spatial structuring of marine populations. For benthic species that have no or little mobility as adults, connectivity is evaluated by analyzing the dispersal of propagules across the seascape. We investigate fine-scale connectivity of coralligenous habitats in Marseille Bay (located in the north-western Mediterranean) sea using high-resolution cartography and a particle-tracking model ran over a range of parameters derived from the biological traits of potential target species. We present annual and seasonal means of various connectivity diagnostics measuring the retention and exchange of propagules among coralligenous patches. A synthetic...

The Arctic Ocean is particularly affected by climate change, with changes in sea ice cover expected to impact phytoplankton primary production. During the Green Edge expedition, the development of the late spring-early summer diatom bloom was studied in relation with the sea ice retreat by multiple transects across the marginal ice zone. Biogenic silica concentrations and uptake rates were measured. In addition, diatom assemblage structures and their associated carbon biomass were determined, along with taxon-specific contributions to total biogenic silica production using the fluorescent dye PDMPO. Results indicate that a diatom bloom developed in open waters close to the ice edge, following the alleviation of light limitation, and extended 20-30 km...

Copepod colonization of organic and inorganic substrata at a deep-sea hydrothermal vent site on the Mid-Atlantic Ridge
Provedor de dados: 5
Autores: Plum, Christoph; Pradillon, Florence; Fujiwara, Yoshihiro; Sarrazin, Jozee.
The few existing studies on deep-sea hydrothermal vent copepods indicate low connectivity with surrounding environments and reveal high endemism among vents. However, the finding of non-endemic copepod species in association with engineer species at different reduced ecosystems poses questions about the dispersal of copepods and the colonization of hydrothermal vents as well as their ecological connectivity.  The objective of this study is to understand copepod colonization patterns at a hydrothermal vent site in response to environmental factors such as temperature and fluid flow as well as the presence of different types of substrata. To address this objective, an in situ experiment was deployed using both organic (woods, pig bones) and inorganic...

The Seasonal and Inter-Annual Fluctuations of Plankton Abundance and Community Structure in a North Atlantic Marine Protected Area
Provedor de dados: 5

Marine Protected Areas have become a major tool for the conservation of marine biodiversity and resources. Yet our understanding of their efficacy is often limited because it is measured for a few biological components, typically top predators or species of commercial interest. To achieve conservation targets, marine protected areas can benefit from ecosystem-based approaches. Within such an approach, documenting the variation of plankton indicators and their covariation with climate is crucial as plankton represent the base of the food webs. With this perspective, we sought to document the variations in the emerging properties of the plankton to better understand the dynamics of the pelagic fishes, mammals and seabirds that inhabit the region. For the...

Brachyuran crab community structure and associated sediment reworking activities in pioneer and young mangroves of French Guiana, South America
Provedor de dados: 5
Autores: Aschenbroich, Adelaide; Michaud, Emma; Stieglitz, Thomas; Fromard, Francois; Gardel, Antoine; Tavares, Marcos; Thouzeau, Gerard.
This study in French Guiana evaluates the changes of crab assemblages and their bioturbation activities between mangrove early stages (pioneer and young mangrove) and within stages by taking their spatial heterogeneity (tidal channels, flat areas, pools) into account. The results show differences in crab assemblage structure between and within the early stages of mangrove in relation to microhabitat and sediment characteristics. The sediment reworking rates are a function of the biomass or density of particular species (Ucides cordatus, Uca cumulanta) and burrower functional groups. Crab species or functional interaction mediate changes in sediment reworking rates suggesting the need to consider entire benthic communities rather than single species. This...

The problems of application of radiocarbon method for estimation of primary production in oligotrophic waters
Provedor de dados: 5
Autores: Krupatkina, D; Berland, B; Maestrini, S.
The errors in primary production estimation by the radiocarbon method may differ from one trophic region to another. Such supposition is based on unequal phytoplanktonic structural characteristics of these regions. These errors are likely to appear rather significant in oligotrophic waters predominated by nano- and ultranano-plankton (the so-called picoplankton). The organic substance of oligotrophic waters is obviously produced by picoplankton for the most part, the need for clarifying possible errors when estimating primary production by the radiocarbon method, which is the purpose of the present work is urgent. For these topics in oligotrophic waters, measurements were carried out in two ways: (1) according to the generally accepted pattern (Sorokin,...

Community composition and species richness of parasitoids infesting Yponomeuta species in the Netherlands
Provedor de dados: 16
Autores: Cleary, Daniel F.R.
Parasitoid assemblages infesting Yponomeuta species in the Netherlands were investigated. Parasitoid species richness and community composition were related to host species, habitat, temporal and spatial variation. Both community structure and species richness did not differ among habitats. There was no significant difference in species richness between years (1994 and 1995) but there was a significant difference in community composition. Community composition and species richness both differed among host species, although this latter result was solely due to the host species Y. evonymellus. There was no significant relationship between community similarity and distance. These results indicate that the parasitoids of the moth genus Yponomeuta in the...

Epibionts on Flexopecten felipponei (Dall, 1922), an uncommon scallop from Argentina
Provedor de dados: 20
Autores: Schejter, L.; Bremec, C.
Flexopecten felipponei (Dall, 1922) is a non-commercial, seldom reported pectinid from the SW Atlantic Ocean. In this contribution we review its taxonomy, describe epifaunal species and their levels of encrustation, and discuss the composition of the macrobenthic assemblage where this scallop Iives. Eighteen epibiont taxa were observed to Iive on the valves of these scallops. The most frequent and abundant epibionts on F. felipponei were serpulids, barnacles, and oysters. Although both valves were encrusted, the left valves had higher percentages of coverage. The benthic community contained 69 invertebrate taxa that generally charaeterize other mid-shelf bottorns between 37°S and 39°S. Eight pea crabs of the species Tumidotheres maculatus (Say, 1818)were...

Autores: Su, Qiang; Huang, Liangmin; Tan, Yehui; Xu, Runlin; Li, Tao; Xu, Zhanzhou; Zhang, Janlin; Qiu, Dajun.
Microzooplankton community composition in the north of South China Sea was investigated during autumn (between September and October), 2004. Dilution technique using chlorophyll a (Chl a) was employed to estimate grazing rates and grazing pressure. The results showed that Polymenophorea Oligotrichida was the dominant group with 16 species, and there were 4 species in Oligotrichina and 11 species in Tintinnina. The ciliates abundance ranged from 9 to 102 ind/m3. Instantaneous growth rates of phytoplankton (k) varied from 0.03 / d to 2.13 / d. Grazing rates of microzooplankton(g) ranged between 0.01 / d and 1.06 / d. The grazing pressure on initial phytoplankton stock (Pi) and primary production (Pp) was 0.089 % - 65.23 % and 33.63 % - 86.04 %, respectively....

Dinámica del ultrafitoplancton en el Mar Argentino
Provedor de dados: 20
Autores: Silva, R.I.
Ultraphytoplankton is composed by a group of organisms phylogenetically diverse, which contribute significantly to the total biomass and primary production in different oceanic and coastal pelagic systems. The success of ultraphytoplankton is attributed to its high efficiency in capturing light and nutrients, due to their small cell size and low sinking rate. The community structure is driven by the interaction among biotic and abiotic variables, such as temperature, nutrients, light and predators. The objective of this work was to assess the ecological importance of ultraphytoplankton organisms at the EPEA station, situated in the Buenos Aires coastal pelagic system (Argentina, SW Atlantic), during the period 2000-2009. In particular, ultraphytoplankton...

Cambio temporal en la estructura de la comunidad coralina del área de Santa Marta - Parque Nacional Natural Tayrona (Caribe colombiano)
Provedor de dados: 20
Autores: Martínez, S.; Acosta, A.
Several predictions have been made, about magnitude and direction of temporal changes in the coral community structure, during the last decade. However, few studies have demonstrated it quantitatively. In order to document such changes, the coral community structure was studied in four continental reefs in the Colombian Caribbean, two in the Santa Marta region: Punta Betín (PB) and Morro Grande Island (MO), and two in the Tayrona National Natural Park (PNNT): Granate cove (GR) and Gayraca bay (GA). Coral composition and cover were quantified in 2002 and compared to base line studies from 1989 (PB, MO &amp; GR) and from 1992 (GA). These variables were quantified by 20 m linear transects between 1.5 m and 29 m depth. After a decade, all reefs lost in average...

For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns.

Variabilite mensuelle du zooplancton et de l'ichtyoplancton dans le golfe de Tunis
Provedor de dados: 20
Autores: Missaoui, H.; El Abed, A.; M'rabet, R.; Romdhane, M.S.; Zarrad, R.; Jarboui, O.
Monthly variability of zooplankton and ichthyoplankton abundance and composition were studied in 6 stations in the Gulf of Tunis between February 2003 and January 2004. Plankton trawls were horizontal, in surface and at night. Study area seems to be influenced by climatic conditions and the outflow of Majreda River that affect the surface temperature and salinity. Copepods, with many abundance peaks in the year, formed the most abundant group (84%) followed by cladocerans (8%) and chaetognaths (3%). The appendicularians, cladocerans and medusae had swarms in the summer, the creseis and the chaetognths in the autun and the zoae larvae in the spring. The highest fish spawning periods was in summer then the highest larva abundance was in winter and...

Asociación bentónicas en bancos de vieira patagónica (Zygochlamys patagonica) en el Mar Argentino
Provedor de dados: 20
Autores: Schejter, L.
The different aspects of the benthic assemblages at the Patagonian scallop beds in the Argentine Sea (SW Atlantic) were studied. The Patagonian scallop (Zygochlamys patagonica) is a commercial species distributed in the Magellanic Biogeographic Province, and has been commercially exploited since 1996. Temporal and spatial studies were performed in the community composition between 39°50'S and 36°15'S, and between 1998 and 2003, concluding that the species association was persistent after more than 7 years of trawling activities. Species composition in an exclusion area (closed to scallop fishing) did not differ from surrounding fished areas during the studied period, showing only a higher scallop biomass. ABC curves showed a pattern coincident with a non...

Estructura de la comunidad del fitoplancton en el área de El Rincón, Mar Argentino (febrero 2011)
Provedor de dados: 20
Autores: Negri, R.M.; Silva, R.I.; Segura, V.; Cucchi Colleoni, A.D.
The El Rincón area in the Argentine continental shelf (coastal sector between 39º S-41º S) is known as one of the main breeding areas of the Argentine anchovy (Engraulis anchoita) Northern stock. However, there is scarce information regarding the structure of the primary producers, base of the pelagic food webs. The aim of this study was to identify the different phytoplanktonic communities in a coastal section in the area (depth lower than 60 m) during February 2011. Mean surface chlorophyll a concentration was 0.72 mg m-3, with the highest value in the innermost station (E34: 1.84 mg m-3) and the lowest in the mid section (E31: 0.24 mg m-3). In depth, similar concentrations were registered, except for the deepest station where the maximum value was...

La salinidad y la distribución espacial de la ictiofauna en el estuario del Río de la Plata
Provedor de dados: 20
Autores: Rico, M.R.
Los ecosistemas estuariales se caracterizan por su alta productividad, baja diversidad biológica y fluctuaciones impredecibles de salinidad. A su vez, la distribución espacial de su ictiofauna resulta en general suficientemente explicada por los patrones de distribución de la salinidad. En particular, en el estuario del Río de la Plata (35° 00' S y 55° 30' W) que presenta una marcada estratificación vertical de densidad, dominada por la salinidad, se analizó cuantitativamente la relación entre dicha variable y la distribución espacial de su ictiofauna demersal. Se procesó y analizó información proveniente de siete campañas de evaluación pesquera realizadas por el Proyecto "Especies Demersales Costeras" del INIDEP en el área de estudio, durante las...

The abundance, biomass and composition of pelagic ciliates in East African lakes of different salinity and trophy
Provedor de dados: 20
Autores: Yasindi, A. W.; Taylor, W. D.
Planktonic ciliates were studied in 17 tropical East African lakes of different salinity and trophic status. Oligotrichs (e.g., Strombidium, Strobilidium and Halteria) and scuticociliates (e.g., Cyclidium, Pleuronema, Cristigera), dominated the ciliate communities. Conductivity and trophic status were the most important environmental variables influencing the distribution of ciliate species in East African lakes. Herbivorous oligotrichs were important in oligotrophic and mesotrophic lakes, as they are in temperate and subtropical lakes, but their importance decreased with increasing chlorophyll a concentration and conductivity. On the other hand, the importance of scuticociliates (primarily bacterivores) increased with increasing chlorophyll a and...

Meiobenthos of the central Arctic Ocean with special emphasis on the nematode community structure
Provedor de dados: 27
Autores: Vanreusel, A.; Clough, L.M.; Jacobsen, K.; Ambrose, W.; Jivaluk, J.; Ryheul, V.; Herman, R.; Vincx, M.
We investigated the abundance of the meiobenthos and the biomass and community structure of the nematodes in the central Arctic Ocean along two separate transects during 1991 and 1994. Meiobenthos abundances ranged from &lt; 100 to 600 individuals per 10 cm², in the same order of magnitude as in other oligotrophic areas of the world's deep ocean. Nematodes were the numerically dominant meiofaunal group at every station. Nematode biomass ranged from &lt; 1 to 48 µg dry weight per 10 cm². A combination of water depth and latitude explained 55% of the variability among stations in nematode biomass and 67% of the variability of total abundance, implying that both vertical and advective fluxes are important sources of food to the meiofaunal communities. The...

Early postlarval fish in the hyperbenthos of the Dutch Delta (south-west Netherlands)
Provedor de dados: 27
Autores: Beyst, B.; Mees, J.; Cattrijsse, A.
Early (post)larval fish constitute a significant part of the temporary hyperbenthos, i.e. of the fauna living in the lower reaches of the water column close to the substratum. Information on the densities and spatial and temporal variations of these stages, as well as on their lengths at the moment of occurrence, can be an important contribution to the knowledge of their dispersion, migrations and to the identification of possible bottlenecks in their recruitment. Therefore the hyperbenthos of the Voordelta, a shallow coastal zone in front of the Dutch Delta, as well as that of the subtidal channels and the intertidal brackish marsh creeks of the Westerschelde Estuary, was sampled monthly during one year by means of a sledge and a stow net. A total of 37...

Determination of seasonal phytoplankton communities, based on quantitative data using a mathematical analysis
Provedor de dados: 27
Autores: Caljon, A.
The definition of algal communities has always been a very discussed subject. We applied a principal component analysis on quantitative phytoplankton data. This ordination technique made it possible to distinguish the algal groups present. This technique is very often applied in the phytosociology of higher plants but less frequently in the phytosociology of algae. Till now this ordination has been used in phycology, merely for marine- and freshwater benthic algae, e.g. the benthic diatoms of rivers (Descy 1976a, b).

Abstract: The objective of this work was to estimate an index of the relative biomass per species, in a medium to large-sized mammal community, as well as to determine how the introduced wild boar (Sus scrofa) fits into this index, and to verify if the occupancy of sites by domestic dogs interferes with those of wild boars and how much the periods of dogs’ activity overlap those of wild boars. The biomass/effort index was measured for each native mammal species and for the introduced wild boar, in two surveyed farms in Brazil’s Western Atlantic Forest range, through the use of camera trappings that were also used to verify if dogs and wild boar overlap in space and activity time. Wild boars seem to dominate the community, just a few years after their...

Local environmental controls of Atlantic Forest tree community assembly on a coastal continental island in southeastern Brazil
Provedor de dados: 39
Autores: Nettesheim,Felipe Cito; Garbin,Mário Luís; Pereira,Marcos Gervasio; Araujo,Dorothy Sue Dunn de.
ABSTRACT Tropical forests with high species diversity are commonly found in rugged montane areas. We investigated causes of local tropical forest tree community assembly on a continental island with heterogeneous terrain. We recorded tree community (absolute species abundance), topography, soil, litter and location in 40 sampling units on two opposite sides of the island with similar heterogeneous terrain. We used transformation based Redundancy Analyses and variation partitioning to determine the contribution of environment (topography, soil and litter), spatial structure (geographic location and Moran Eigenvector Maps) and the shared effects of these to explain community assembly. The environment made a significant contribution to explain tree community...

Land flatworms show high endemism due to their restricted mobility. In southern Brazil, land flatworm communities have been found mainly in areas of ombrophilous forests. Thus, this study documents land planarian species composition in remnants of deciduous seasonal forest in the northeast region of southern Brazil. Direct, diurnal samplings reveal the occurrence of 26 species of land flatworms, of which one belongs to the subfamily Rhynchodeminae and the others to the subfamily Geoplaninae. The Rhynchodeminae genus Rhynchodemus Leidy 1851 and the following Geoplaninae genera occurred: CephaloflexaCarbayo &amp; Leal-Zanchet, 2003, Choeradoplana Graff, 1896, Imbira Carbayo et al., 2013, IssocaFroehlich, 1955, LuteostriataCarbayo, 2010, Obama Carbayo et al.,...
