Ability of taxonomic diversity indices to discriminate coastal lagoon environments based on macrophyte communities ArchiMer
Mouillot, David; Gaillard, Sylvain; Aliaume, Catherine; Verlaque, Marc; Belsher, Thomas; Troussellier, Marc; Chi, Thang.
Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication levels and aquaculture intensity. Based on macrophyte communities associated with soft substrates, two indices of taxonomic diversity (the "average taxonomic distinctness" (Delta(+)) and the "variation in taxonomic distinctness" (Lambda(+))) were used to discriminate four of these lagoons (Thau, Salse-Leucate, Bages-Sigean and Mauguio). Bages-Sigean presented a significant higher average taxonomic distinctness (p < 0.05) and Salse-Leucate had a significant higher variation in taxonomic distinctness (p <...

Cultural practices and risk of shellfish pathogen exchanges : the oyster aquaculture in France ArchiMer
Miossec, Laurence; Girard, Sophie; Czerwinski, N..
The first national census concerning shellfish culture in France was carried out in 2002. The main purpose was to provide accurate and comprehensive information on the number and structure of the companies using an in depth review of production factors (leases, plants, equipment's, labour and qualifications), and a survey of cultural practices up to the market level. Moreover, the census aimed to quantify the bivalve sales dedicated to consumption and to measure the livestock transfers among rearing shellfish production areas at different developmental stages: spat, intermediate products and fully grown marketable products. The French oyster production reached 109 000 metric tons in 2001. The main production was observed in Poitou-Charentes region...

Disruption of ecosystem processes in western North America by invasive species RChHN
Dukes,Jeffrey S.; Mooney,Harold A..
Many ecosystems of western North America have been dramatically changed by non-native species. Here, we review ecological impacts of 56 plant, animal, fungus, and protist species that were brought to this region by humans. We discuss characteristics of invasive species that can lead to major ecosystem impacts, and explore how invasive species alter many different attributes of ecosystems. Specifically, we include examples of invasive species that affect geomorphology, fire regimes, hydrology, microclimate, atmospheric composition, nutrient cycling, and productivity. Finally, we review the direct consequences of biological invasions for some native species. We summarize examples from this paper in Appendix 1. Our examples illustrate how, as invasive species...

Do what I say, not what I do: Are we linking research and decision-making about invasive species in Patagonia? Ecología austral
Anderson,Christopher D; Valenzuela,Alejandro E. J.
Invasion biology is well-positioned epistemologically, theoretically and practically to address the challenge of being both scientifically and socially relevant. Yet, how well are we achieving these two dimensions of academic inquiry and impact? We explored this issue by a) surveying Argentine invasion biology practitioners (students, scientists and managers) to determine the types of collaborations they report and their stated preferences regarding research thematic priorities (autecology, impacts, management, patterns/distribution, presence/absence, processes/mechanisms, policy, social), and b) reviewing the invasion biology literature in Argentine Patagonia to establish research productivity, the publications' taxonomic, methodological (review,...

Exotic plant invasions to the mediterranean region of Chile: causes, history and impacts RChHN
FIGUEROA,JAVIER A.; CASTRO,SERGIO A.; MARQUET,PABLO A.; JAKSIC,FABIAN M..
We review the literature on patterns, causes, processes and impacts of exotic plants, primarily in the mediterranean region of Chile, considering three major non-independent drivers of the invasion process: (a) Availability of exotic species propagules, (b) attributes of the local communities in which exotic species establish and through which they will eventually spread out, and (c) attributes of exotic species that either facilitate or constraint their spread into new sites. Regarding availability of propagules, central Chile matorral presents the communities with the greatest incidence of naturalized herbs, followed by the sclerophyllous forest and the espinal scrubland in the coastal range. In contrast, north-central communities have lower numbers and...

Human use and small mammal communities of Araucaria forests in Neuquén, Argentina Mastozool. neotrop.
Shepherd,John D.; Ditgen,Rebecca S..
Small mammals were sampled in five closed, humid, Araucaria araucana forests that differed in the degree of anthropogenic disturbance in southwestern Neuquén province. Nine species were captured in 3416 trap nights. Abrothrix longipilis and Oligoryzomys longicaudatus made up 88% of all captures. Small mammal relative abundance was 52 times higher where grazing was absent compared to a site with intense grazing pressure. Seed predation, primarily by livestock and feral exotic mammals, varied from 59.7% to 15.1% of marked seeds per day. Small mammal community productivity and composition were correlated with understory structure (Mantel test, r = 0.529, p = 0.04), and with rates of seed predation (r = -0.91, n = 4, p = 0.08). Forests with less complex...

Hyper abundant mesopredators and bird extinction in an Atlantic forest island Rev. Bras. Zool.
Galetti,Mauro; Bovendorp,Ricardo S.; Fadini,Rodrigo F.; Gussoni,Carlos O. A.; Rodrigues,Marcos; Alvarez,Ariane D.; Guimarães Jr,Paulo R.; Alves,Kaiser.
Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators such as marmosets and coatis, introduced more than 20 years ago. This indiscriminate introduction of mammals may have affected directly the bird community, nowadays represented by 100 species comprised mainly by water-crossing birds, being 73 forest-dwelling species. A small component of these remnant bird species nests in tree holes and on the forest floor, null model analysis suggest that birds within...

Non-indigenous marine and estuarine species in The Netherlands Naturalis
Wolff, W.J..
An overview is presented of non-indigenous marine and estuarine plant and animal species recorded from The Netherlands. In this list both exotic species from outside NW Europe and non-indigenous species from elsewhere in NW Europe are enumerated. Species that have been suggested to be non-indigenous in The Netherlands but for which insufficient evidence could be found are discussed shortly as well. The list is based mainly on literature data supplemented by own observations of the author. At least 99 plant and animal species have been introduced from elsewhere in the world. Another 13 species have been introduced from other parts of NW Europe. The third category of dubious non-indigenous species enumerates 37 species. The list is preceded by an...

Physical, chemical and mechanical properties of Australian cedar wood cultivated in Corupá, Santa Catarina State, Brazil PFB - Pesquisa Florestal Brasileira
Trianoski, Rosilani; Matos, Jorge Luis Monteiro de; Iwakiri, Setsuo.
The Australian cedar (Toona ciliata M. Roem) is a species of high commercial value, with characteristics similar to native mahogany and cedar, which has been highlighted in forest plantations in Brazil, whose wood should be the subject of technological research. The objective of this study was to evaluate the physical, chemical and mechanical properties from planted stands of 18 years old. The wood showed low density (0.330 g cm3), low average dimensional stability (anisotropy: 2.22), high content of extractives (10.33%) and moderate mechanical properties: MOR and MOE to bending: 498 kgf cm-2 and 66,163 kgf cm-2; MOR and MOE for parallel compression: 258 kgf cm-2 and 100.813 kgf cm-2; shear: 82 kgf cm-2 and medium hardness: 208 kgf.

POLYCHAETES FROM RED MANGROVE (Rhizophora mangle) AND THEIR RELATIONSHIP WITH THE WATER CONDITIONS IN THE GULF OF URABÁ, COLOMBIAN CARIBBEAN Acta biol.Colomb.
FERNÁNDEZ-RODRÍGUEZ,Vanessa; LONDOÑO-MESA,Mario H.; RAMÍREZ-RESTREPO,John Jairo.
Polychaetes play a significant role in benthic communities' ecology; they dominate the infauna, recycle nutrients from the water column and are commonly used as biological indicators. Along the Gulf of Urabá (Colombian Caribbean), particularly for the zones of the Marirrío Bay and the Rionegro Cove, there are no reports about ecological aspects of polychaete species; only a few taxonomic studies have been conducted. In this research we evaluate the relationship between polychaete species associated with red mangrove roots, Rhizophora mangle, and some physicochemical variables of the water column; also, we made some notes about the spatial distributions of polychaetes species within the two study areas. We found that the environmental variables that best...

Prospecting molecular markers to distinguish Cichla kelberi, C. monoculus and C. piquiti Biological Sciences
Gasques, Luciano Seraphim; Prioli, Sônia Maria Alves Pinto; Prioli, Alberto José; Gonçalves, Daniela Dib; Fabrin, Thomaz Manzini Carrenho.
Peacock bass, a fish of the genus Cichla, is an exotic species from the upper river Paraná floodplain in which the species Cichla kelberi and C. piquiti have been confirmed, coupled to the specie C. monoculus upstream in the Capivara and Taquaruçu dams. The introduction of this genus has caused negative impacts on the diversity of native species. Current research prospects DNA sequences capable of distinguishing the three species and provide molecular data for the taxonomic characterization of the species in the upper Paraná River basin.  Sequencing of nuclear (tmo4c4, dlx2 and bmp4) and mitochondrial (cox1, cytb) loci were done from fish of the three species of the genus Cichla reported in the literature of the upper Paraná River basin. Sequence analysis...

The exotic jellyfish Blackfordia virginica introduced into the Netherlands (Cnidaria: Hydrozoa) Naturalis
Faasse, M.A.; Melchers, M..
In August 2014 the exotic jellyfish Blackfordia virginica was captured in the harbour of Amsterdam. This is the first confirmed record of this species in the Netherlands, although in October 2013 a possible specimen was filmed and released. This indicates that the species might be established in the Amsterdam area, although repeated introduction with ballast water cannot be ruled out. In September 2014 hydrozoan polyp colonies closely resembling those of B. virginica were collected near IJmuiden in the Noordzeekanaal, a canal connecting Amsterdam with the North Sea at IJmuiden.
