Viability and Risk Assessment in Species Restoration: Planning Reintroductions for the Wild Boar, a Potential Disease Reservoir
Provedor de dados: 7
Autores: Kramer-Schadt, Stephanie; UFZ  Centre for Environmental Research; stephanie.kramer@ufz.de; Thulke, Hans-Hermann; UFZ  Centre for Environmental Research; hans.thulke@ufz.de.
The reintroduction of large mammals is often considered a priority conservation action in highly industrialized countries in which many of these species have been depleted. However, species reintroduction after decades of absence may involve important risks for human activities and ecological communities, such as favoring the spread of diseases. An example of a potentially troublesome reintroduction is the wild boar, which may act as a reservoir of diseases, e.g., classical swine fever, and cause high economic losses, and has become a species of concern in several European countries for both ecological and recreational reasons. Failure to prevent the disease consequences of species restoration can negate its conservation benefits. Here we evaluated the...

Impact of rainbow trout on aquatic invertebrate communities in subtropical mountain streams of northwest Argentina
Provedor de dados: 67
Autores: Molineri,Carlos.
The present study was conducted to assess the effect of rainbow trout introduction on benthic invertebrate communities, stratified as epibenthos and infauna. Two main questions are explored: 1) do the trout-invaded streams show a different community structure than the streams with autochthonous fish?, and 2) does the presence of trout affect differentially the epibenthos and the infauna? Epibenthic and infaunal samples, drift samples and fish stomach content were sampled four times from three stations to assess the impact of rainbow trout (Oncorhynchus mykiss) on the invertebrate aquatic fauna. Only one species of native fish was recorded in the studied sites, the siluriform Trichomycterus corduvense. Both fish species were found always in allopatry. The...

Checklist of the macroalgae of Thau Lagoon (Herault, France), a hot spot of marine species introduction in Europe
Provedor de dados: 5
Autores: Verlaque, Marc.
A checklist of macroalgae in Thau Lagoon (Herault, France), based on literature records and new collections, is given. Using present-day taxonomy, 196 taxa and stadia of macroalgae have been identified to date. Sixty of these were no longer found in the samples, 36 were new to the lagoon, and the taxonomic identity of 15 species was amended. Twenty-five new introduced taxa were identified, giving a total of 45 introduced macroalgae for the flora (23% of total). Among these, 17 taxa and several genera (Acrorhrix, Chondrus, Dasysiphonia (?), Prionitis) are new to the Mediterranean Sea and 12 are new to Europe. The majority (43 taxa) may originate from the Pacific region, having arrived either directly or via other aquaculture sites. A highly probable vector...

Autores: Verlaque, Marc; Auby, Isabelle; Plus, Martin; Belsher, Thomas.
An inventory of the marine macrophytes introduced into the Arcachon Basin has been carried out through an exhaustive bibliographical analysis complemented by several sampling campaign made in November 2005, July 2006, February and December 2007. As a result, 22 introduced species have been listed. Nine of them are new to the region, and Herposiphonia parca and Pterosiphonia tanakae, are recorded for the first time from the Atlantic Ocean. Of this exotic flora, 17 species have also been introduced into the Thau Lagoon (France, Mediterranean). Except for some old introductions for which the most probable vector is the shipping, an introduction along with shellfish transfers, directly from Japan or via other aquaculture sites is highly probable.

The Pacific Mani la clam (Tapes philippinamm) was introduccd in France be tween 1972 and 1975 by the SATMAR Corporation , and in England through the Conwy Laboratory in 1980. Initially. spat were introduced and later adults, both from the west coast of North America (Puget Sound area). Aquaculture production in France started from adults. Until 1975, experiments with the spat were conducted at half-industrial scale and research activities and plans to transfer the knowledge were set up. The breeding began at first on the French Atlantic coast in intertidal areas and at the same time in oyster ponds. Characteristics of the new cu lture are presented in th is paper.

Spatial distribution in a temperate coastal ecosystem of the wild stock of the farmed oyster Crassostrea gigas (Thunberg)
Provedor de dados: 5
Autores: Cognie, B; Haure, Joel; Barille, L.
The Pacific oyster, Crassostrea gigas, well known throughout the world because of its ability to adapt to a wide range of environmental conditions, was introduced for cultivation into France on a massive scale in the 1970s. With global warming, the reproductive population, confined at the beginning to the south of the French Atlantic coast, became established at more northern latitudes (above 45 degrees 58'N), and wild C gigas began to colonize coastal areas such as our study site, Bourgneuf Bay (1 degrees-2 degrees W, 46 degrees-47 degrees N), an oyster-farming site. An original approach, based on orthophotograph analysis and in situ biomass sampling, revealed that, in the northern part of this bay, more than 70% of the total C gigas biomass was composed...

Dietary breadth and trophic position of introduced European catfish Silurus glanis in the Tarn River (Garonne River basin), southwest France
Provedor de dados: 5
Autores: Syvaeranta, Jari; Cucherousset, Julien; Kopp, Dorothee; Crivelli, Alain; Cereghino, Regis; Santoul, Frederic.
Although being a widely introduced and successfully established species, the European catfish Silurus glanis L. (the world’s third largest freshwater fish) remains poorly studied in its introduced areas. Here we studied the trophic ecology of non-native European catfish in a large river system in south-western France using stomach content and stable isotope analyses (SIA). We used fin samples for SIA of catfish and hence tested the validity of using fin tissue as a proxy for muscle in SIA. The mean δ15N and δ13C values analysed from fin tissues did not differ from those analysed from muscle tissue and reflected strong and consistent relationships (r2 = 0.95 for carbon and r2 = 0.98 for nitrogen). The δ15N values varied almost 5‰ among the analysed catfish...

Invasion of the eastern Bay of Biscay by the nassariid gastropod Cyclope neritea: origin and effects on resident fauna
Provedor de dados: 5
Autores: Bachelet, G; Simon-bouhet, B; Desclaux, C; Garcia-meunier, P; Mairesse, G; De Montaudouin, X; Raigne, H; Randriambao, K; Sauriau, Pierre-guy; Viard, F.
The distribution area of the nassariid gastropod Cyclope neritea (L.) includes the Mediterranean and the Black Sea, as well as the Atlantic coasts of the southern Iberian Peninsula. The species has spread north to the eastern Bay of Biscay (Arcachon Bay in 1976, Marennes-Oleron area and Morbihan Gulf in 1983-84). This spread might be explained either by (1) a natural spread favoured by environmental changes (e.g. an increase of temperature) or (2) a sudden range expansion due to the introduction of individuals from distant native populations. Molecular genetic analyses based on mitochondrial markers suggest that the present C. neritea population in Arcachon Bay has been introduced, probably unintentionally with oyster transfers, from several source...

Drastic changes in the amphipod fauna (Crustacea) of Dutch inland waters during the last 25 years
Provedor de dados: 16
Autores: Pinkster, Sjouk; Scheepmaker, Maarten; Platvoet, Dirk; Broodbakker, Nico.
After the introduction of Gammarus tigrinus in The Netherlands some 25 years ago and of other recently invading amphipods (Crangonyx pseudogracilis and Corophium curvispinum) the native species decreased, the invaders increased. The success of these invaders and its impact on the local amphipod fauna is discussed. Electrophoretic tests give evidence that a second invasion of Gammarus tigrinus, this time from Germany, is taking place. Some predictions about future developments are made.

A revision of Jatropha (Euphorbiaceae) in Malesia
Provedor de dados: 16
Autores: Welzen, P.C. van; Sweet, F.S.T.; Fernández-Casas, F.J.
Jatropha, a widespread, species rich genus, ranges from the Americas and Caribbean to Africa and India. In Malesia five species occur, all of which were introduced and originated in Central and South America. The five species are revised and an identification key, nomenclature, descriptions, distributions, ecology, vernacular names, uses and notes are provided. Special attention is given to the uses of J. curcas, because it is steadily gaining popularity as a potential biofuel plant and, because of that, is being cultivated more often.

The purpose of this research was to demonstrate the dependant relationship between the Argentine ant Linepithema humile Mayr, plant coverage, and human settlements. A method was designed in order to sample the presence of the Argentine ant and other ant species that may had influenced L. humile distribution, under different types of vegetation and percentages of plant coverage, taking in consideration the distance from human settlements. Eight sample stations were established. Four of these stations were found on a dwelling home and the other four were found on similar areas, but far from human settlements. Three transects were established from the center of each sampling station (Tt1, shrublike vegetation, Tt2, herblike vegetation and Tt3, no vegetation)....

Macrophytes of Lake Victoria and succession after invasion of Water Hyacinth
Provedor de dados: 20
Autores: Omondi, R.; Kusewa, Mwende.
The distribution of Lake Victoria (Kenya) macrophytes is described. Succession of macrophytes in the lake became more dramatic and dynamic after invasion of water hyacinth. The weed pushes and smothers other free-floating macrophytes like Pistia stratiotes. It then provides substrates for the emergent Vossia cuspidata, which later reduces its population by competition for light and nutrients. The noxious weed is believed to have led to extinction of Azolla nilotica in the lake.

Efecto del alga invasora Undaria pinnatifida sobre la comunidad de peces de arrecife en los golfos Norpatagónicos
Provedor de dados: 20
Autores: Irigoyen, A.J.
This study investigates the impact of Undaria pinnatifida on the reef  fish assemblage associated with the coastal rocky reefs of Golfo Nuevo in northern Patagonia, Argentina. Undaria pinnatifida is a laminarian kelp, indigenous to the temperate regions of Japan, China and Korea. It has spread around the world by international shipping and has also been introduced in some regions for mariculture. Its expansion into the northern Patagonian gulfs and Peninsula Valdes, a UNESCO Natural Heritage Site, may threaten eco-tourism activities that depend on local biodiversity and the esthetic quality of the ecosystem. In particular, there is concern about the impact of Undaria on a variety of recreational activities including diving, angling and spear fishing, which...

Los organismos no nativos son frecuentemente transportados por las actividades humanas  y accidental o premeditadamente introducidos, dando al ambiente un matiz diferente del  original. Cuando las condiciones son favorables, los organismos recién llegados pueden  reproducirse y asentarse con éxito. Sin embargo cuando las interacciones de los organismos  recién llegados con el nuevo ambiente y las comunidades asentadas son destructivas, la  introducción se conoce como invasión (Aguilar-Perera y Tuz-Sulub, 2010). Los cambios en  la biodiversidad marina pueden dar lugar a alteraciones de las comunidades o poblaciones  existentes y a la pérdida o extinción de especies e incluso provocar la invasión de especies  nuevas.Amphibalanus reticulatus aunque es nativa...

Do Morphological Similarities and human-induced dispersal explain the non-native occurrence of Serpulidae (Annelida) in Southwest Atlantic? Taxonomic detailing is the key
Provedor de dados: 84
Autores: Rodrigues,Andrielle Raposo; Skinner,Luis Felipe; Brasil,Ana Claudia dos Santos.
Abstract Species of Serpulidae are common on benthic and biofouling communities, occurring attached on both natural and artificial substrates. In this paper, Serpulids were collected from intertidal to subtidal areas, on rocky shore and suspended artificial plates in port areas. Herein we report three new records of serpulid species to the coast of Rio de Janeiro, Brazil. We also discuss the misidentification of Spirobranchus tetraceros, which was previously reported to the north of Rio de Janeiro.

Morphological and genetic diversity in Callithrix hybrids in an anthropogenic area in southeastern Brazil (Primates: Cebidae: Callitrichinae)
Provedor de dados: 103
Autores: Cezar,Adrielle M.; Pessôa,Leila M.; Bonvicino,Cibele R.
ABSTRACT Two species of Callithrix, C. jacchus (Linnaeus, 1758) and C. penicillata (É. Geoffroy, 1812), are considered invasive in Rio de Janeiro. This study determined the genetic and morphological diversity and verified the species involved in the hybridization of 10 individuals from the municipalities of Silva Jardim (N = 9) and Rio das Ostras (N = 1). We compared the external morphology and skull of C. jacchus (N = 15) and C. penicillata (N = 14) specimens deposited in the collection of the National Museum of Rio de Janeiro (MN- UFRJ). Phylogenetic (maximum likelihood and Bayesian inference) and phylogeographical analyses (network analysis) were performed based on cytochrome b sequences. These analyses included hybrids from the metropolitan region of...

A dichotomous species of Codium (Bryopsidales, Chlorophyta) is colonizing northern Chile
Provedor de dados: 97
Autores: GONZÁLEZ,ALEJANDRA; SANTELICES,BERNABÉ.
In late 2001 and early 2002, a dichotomous species of Codium appeared colonizing the low intertidal and shallow subtidal bottoms of Caldera Bay, northern Chile (27° 03’ S, 70° 51’ W). Due to the ecological and economic impact the species is having in Caldera Bay and its potential spread along the Chilean coastline, we studied the taxonomic identity of the species and examined its relationships with other dichotomous species of Codium reported for temperate Pacific South America. Morphological analyses suggest that the seaweeds from Caldera Bay belong to Codium fragile (Suringar) Hariot. Not only is there strong agreement in internal and external morphological characters, but among all the species reported for Peru and Chile, this is the only one exhibiting...

Reappearance and seasonality of Phyllorhiza punctata von Lendenfeld (Cnidaria, Scyphozoa, Rhizostomeae) medusae in southern Brazil
Provedor de dados: 104
Autores: Haddad,Maria A.; Nogueira Júnior,Miodeli.
The scyphozoan Phyllorhiza punctata von Lendenfeld, 1884 (Mastigiidae), known only from Indo-Pacific waters prior to the 1950s, is today found far from its original distribution, probably due to human activities. First seen in 1955 in Brazilian waters, medusae were found in southern and southeastern coasts, disappearing (at least as a medusa) in the early 1960's. Another population was found in the late 1990's, in the state of Bahia, and again in late 2001, many sightings were reported along the coasts of Paraná and Santa Catarina (25º20'S, 48º12'W to 27º26'S, 48º22'W). A large summer bloom, followed by decline and disappearance in winter and spring, occurs every year since then. The reasons for this recent mass occurrence are unknown. Despite few...

Introduced ascidians in Paranaguá Bay, Paraná, southern Brazil
Provedor de dados: 104
Autores: Rocha,Rosana M. da; Kremer,Laura P.
Exotic (introduced) species are a growing problem in ports worldwide and comprise the most important impacts in marine ecosystems. Periodic monitoring to detect introduced species is extremely important for effective population control. Here we sampled ascidian species near the port of Paranaguá for a taxonomic study of this fauna to attempt to detect introduced species. Larval stages in ascidians are short-lived, and dispersal is restricted to small distances, and so ascidians are very good bioindicators for exotic introductions due to ship transport. Four locations were sampled within Paranaguá Bay (Ilha das Cobras, Pier Tenenge, Ilha do Mel and Ilha da Galheta) and one location outside of the bay (Parque dos Meros). Information for the nearby fauna and...

Provedor de dados: 104
Autores: Álvares,Éder Sandro Soares; De Maria,Mário.
Cyrtophora Simon, 1864 comprises 36 species that occur in the Old World and Australia. Cyrtophora citricola (Forskål, 1775) is widespread and has been introduced in the Neotropical region, in Colombia and Hispaniola. Here is presented the first record of this species in Brazil, in the municipalities of Belo Horizonte and Prudente de Morais, State of Minas Gerais. The specimens studied show variations in coloration and in the abdomen's format, but the genital structure is the same as observed in specimens of C. citricola.

 Achatina fulica, known as Giant African Snail (GAS), was introduced in Brazil as a substitute for the European escargot, Helix aspersa maxima. However, its cultivation was abandoned and the mollusk became an invasive species, found throughout Brazil and causing damage to health and the environment. In this context, this study analyzed the knowledge of the population about the damage caused by GAS, seeking to reveal a regional scenario on this issue. This exploratory and cross-sectional study was conducted by means of a questionnaire applied to 150 people, which obtained sociodemographic characteristics of respondents and specific responses about the knowledge and handling of GAS. The results showed that most of the respondents know the snail and are...

Provedor de dados: 42
Autores: BELTRAMINO,ARIEL A.; VOGLER,ROBERTO E.; RUMI,ALEJANDRA; GUZMÁN,LEILA B.; MARTÍN,STELLA M.; PESO,JUANA G.
ABSTRACT The exotic land gastropod Ovachlamys fulgens (Gude, 1900), aka the jumping snail, was registered in Eldorado city, Misiones province, constituting the first documented record of that species in Argentina-and for all of South America as well. Identities of the individuals were confirmed through morphological examination, and by a DNA sequencing of the cytochrome oxidase subunit I gene. DNA sequences for the mitochondrial 16S-rRNA and the nuclear 18S-rRNA genes were also obtained from the morphologically-confirmed specimens to gain insights into the genetic background of this species in Argentina, and as additional markers for enhancing the rapidity of identification by governmental authorities who are responsible for managing the presence of exotic...

First record of the invasive tapeworm, Schyzocotyle acheilognathi (Pseudophyllidea; Bothriocephalidae) in native freshwater fish, Brazil
Provedor de dados: 42
Autores: SOUZA,GEOVANE A. DE; MORESCA,VICTOR O.; TEIXEIRA,GUSTAVO M.; JEREP,FERNANDO C.; AGUIAR,ALINE.
ABSTRACT Schyzocotyle acheilognathi is a tapeworm cestode commonly found in native freshwater fishes from Asia. This cestode has low host specificity and for that reason it has been registered parasitizing more than 200 cultured and wild fish species, besides amphibians, reptiles and birds from different regions of the world. With a high pathogenic potential, S. acheilognathi may cause mortalities in highly infected fish. In South America, Schyzocotyle was reported in Cyprinus carpio from a Brazilian fish farm at the municipality of Cornélio Procópio, northern Paraná State and from the natural environment in C. carpio from Neuquen River, Patagonia, Argentina. So far, there has been no report of this parasite in South American native fishes. Herein we...

Introduced and cryptogenic species and their management in Paranaguá Bay, Brazil
Provedor de dados: 52
Autores: Neves,Carolina Somaio; Rocha,Rosana Moreira da.
The aim of this work was to identify the introduced and cryptogenic species in encrusting and associated communities of hard substrates in Paranaguá Bay, Brazil, and to attempt to determine which of these species could negatively affect the local community to suggest management strategies for these species. At least four introduced species were found - a large number in comparison with other port surveys. These were the hydrozoan Garveia franciscana Torrey, 1902, the polychaete Polydora cornuta Bosc, 1902, the barnacles Amphibalanus reticulatus (Utinoni, 1967) and Striatobalanus amaryllis Darwin, 1854, all with potentially harmful impacts. Of the 33 cryptogenic species, four were also listed in the literature as causing negative effects. We propose the...
