A preliminary evaluation of the European Non-native Species in Aquaculture Risk Assessment Scheme applied to species listed on Annex IV of the EU Alien Species Regulation ArchiMer
Copp, G. H.; Godard, M. J.; Russell, I. C.; Peeler, E. J.; Gherardi, F.; Tricarico, E.; Miossec, Laurence; Goulletquer, Philippe; Almeida, D.; Britton, J. R.; Vilizzi, L.; Mumford, J.; Williams, C.; Reading, A.; Rees, E. M. A.; Merino-aguirre, R..
Developed for carrying out risk assessments under the European Commission (EC) Council Regulation No 708/2007 concerning the use of alien and locally absent species in aquaculture (ASR), the European Non-native Species in Aquaculture Risk Assessment Scheme (ENSARS) is briefly summarised, and the ‘Organism’ module is applied to the 24 species listed in ASR's Annex IV. Four other ENSARS modules (Infectious Agent, Facility, Pathway, and Socio-economic) were used to assess two case study species (European catfish Silurus glanis L. and red swamp crayfish Procambarus clarkii Girard). No Annex IV species was categorised as low risk, 10 as moderately low risk, 12 as medium risk, two as moderately high risk and none as high risk. The results are discussed and...

An Immune System Perspective on Ecosystem Management Ecology and Society
Janssen, Marco A; Indiana University; maajanss@indiana.edu.
A new perspective for studying the complex interactions between human activities and ecosystems is proposed. It is argued that biological immune systems share a number of similarities with ecological economic systems in terms of function. These similarities include the system's ability to recognize harmful invasions, design measures to control and destroy these invasions, and remember successful response strategies. Studying both the similarities and the differences between immune systems and ecological economic systems can provide new insights on ecosystem management.

Avaliação dos problemas enfrentados no manejo do caramujo gigante africano Achatina fulica (Gastropoda: Pulmonata) no Brasil Rev. Bras. Zool.
Colley,Eduardo; Fischer,Marta Luciane.
The giant African snail Achatina fulica Bowdich, 1822 was introduced into Paraná, Brazil, in the 1980s. Since then, it has spread across the country, despite its known invasive status on a global scale. The main objective of this study was to assess the problems faced in the management of the giant African snail. To accomplish that, we gathered and analyzed information available on the internet, scientific databases, field studies, as well as interviews and consultations with official agencies, NGOs, museums, the scientific community and people that coexist with the species. Despite the fact that extensive information has been generated regarding A. fulica (1,340 articles, 65 summaries in national annals, 40,700 pages on the internet), essential to promote...

Cooperation, Spatial-Dynamic Externalities, and Invasive Species Management AgEcon
Epanchin-Niell, Rebecca S.; Wilen, James E..
Most terrestrial biological invasions occur in landscapes comprising numerous, independently managed properties. Thus, control of invasion spread generally depends on the choices of many managers, each deciding the extent to control invasions on their property. Here we develop a spatially-explicit, integrated model of invasion spread and human behavior to examine how people’s control choices under laissez-faire affect patterns of invasion spread and the total costs and damages imposed by an invader. We evaluate how characteristics of the bioeconomic and social system, including the extent of cooperation among managers, affect the divergence between socially optimal and private control efforts. We find that system-wide invasion externalities generally...

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...

E-commerce of freshwater aquarium fishes: potential disseminator of exotic species in Brazil - doi: 10.4025/actascibiolsci.v32i3.3919 Biological Sciences
Magalhães, André Lincoln Barroso de; Universidade Federal de Minas Gerais, Belo Horizonte, 2 Centro Universitário UNA, Rua José Cláudio Rezende, 80, 30455-590, Belo Horizonte, Minas Gerais, Brasil; Jacobi, Claudia Maria; Universidade Federal de Minas Gerais, Avenida Antônio Carlos, 6627, 31270-901, Belo Horizonte, Minas Gerais, Brasil.
The availability of freshwater aquarium fish species for sale was surveyed from July 2005 to June 2006 in Brazilian electronic commerce and the Orkut website. São Paulo was the leading state regarding virtual shops, auctions on Arremate/Mercado Livre, and hobbyists on Orkut, with 52, 44 and 46%, respectively. The Southeast and South regions led the offer of pest species such as C. carpio, C. auratus and P. reticulate. Among the 207 species for sale, 14 species considered potential pests were identified, contrasting with only one page that warned about the dangers of aquarium dumping. The easy access to fish (especially the potential pest species) through e-commerce and Orkut, together with the low total price (unitary value + shipping and handling ranging...

Expansión poblacional de una especie introducida en la Argentina: la ardilla de vientre rojo Callosciurus erythraeus Mastozool. neotrop.
Guichón,M. Laura; Bello,Marcelo; Fasola,Laura.
Biological invasions are one of the major threats to biodiversity and ecosystem functioning, and they provoke economic losses to productive systems. A wild population of the Red-Bellied Squirrel Callosciurus erythraeus, native to South-east Asia, has established in the province a Buenos Aires (Argentina) since 1973. The objective of this study is to assess the spatial distribution of the Red-Bellied Squirrel and describe the opinion of local inhabitants regarding the presence of this exotic species. We conducted 312 interviews in the district of Luján (original release site of this species) and other neighbouring districts, between August 2003 and March 2004. The area of the range distribution of squirrels was calculated using the minimum convex polygon...

Experimental assessment of oyster transfers as a vector for macroalgal introductions ArchiMer
Mineur, Frederic; Belsher, Thomas; Johnson, Mark P.; Maggs, Christine A.; Verlaque, Marc.
Introduction of non-indigenous species can alter marine communities and ecosystems. In shellfish farming, transfer of livestock, especially oysters, is a common practice and potentially constitutes a pathway for non-indigenous introductions. Many species of seaweeds are believed to have been accidentally introduced in association with these transfers, but there is little direct evidence. We experimentally simulated the transfer of oysters from the Thau Lagoon (France). These transfers involved increasing periods of aerial emersion and additional brine and hot water treatments. The brine and hot water treatments were evaluated as a means of reducing the probability of algal introductions with oyster transfers. Shells were cultured for 40 days in...

Harmonia axyridis in Chile: a new threat Ciencia e Investigación Agraria
Grez,Audrey; Zaviezo,Tania; González,Guillermo; Rothmann,Sergio.
In this work, we document the presence of Harmonia axyridis in Chile, an invasive coccinellid species that has had negative effects in other regions of the world, such as: impacts on non-target arthropods, invasions of houses and fruit damage. This species has been found in the last three years in the Metropolitan and Valparaíso regions, in crops, pine plantations and inside houses. We warn about the consequences of the introduction of this species to Chile and claim to take actions to avoid its spread in the country.

Insight on Invasions and Resilience Derived from Spatiotemporal Discontinuities of Biomass at Local and Regional Scales Ecology and Society
Angeler, David G; Swedish University of Agricultural Sciences, Department of Aquatic Sciences and Assessment; david.angeler@slu.se; Allen, Craig R; U.S. Geological Survey, Nebraska Cooperative Fish and Wildlife Research Unit; School of Natural Resources, University of Nebraska, Lincoln; allencr@unl.edu; Johnson, Richard K; Swedish University of Agricultural Sciences, Department of Aquatic Sciences and Assessment; richard.johnson@slu.se.
Understanding the social and ecological consequences of species invasions is complicated by nonlinearities in processes, and differences in process and structure as scale is changed. Here we use discontinuity analyses to investigate nonlinear patterns in the distribution of biomass of an invasive nuisance species that could indicate scale-specific organization. We analyze biomass patterns in the flagellate Gonyostomum semen (Raphidophyta) in 75 boreal lakes during an 11-year period (1997-2007). With simulations using a unimodal null model and cluster analysis, we identified regional groupings of lakes based on their biomass patterns. We evaluated the variability of membership of individual lakes in regional biomass groups. Temporal trends in local and...

Invasive carnivores in Patagonia: defining priorities for their management using the American mink (Neovison vison) as a case study Ecología austral
Fasola,Laura; Valenzuela,Alejandro Eduardo Jorge.
The American mink is a widespread invasive carnivore in Patagonia, and due to its foraging behavior that allows it to exploit a wide variety of prey, it is the exotic carnivore with the highest potential impact on the region's biodiversity. Available regional information on mink presence/absence, as well as abundance estimations, is scarce even though it is vital to plan management actions. Here, we integrate the confirmed distribution of mink in Patagonia with its potential presence for areas where information is lacking, based on the location of animal releases and estimated dispersal rates. We propose an Area Prioritization Tool (APT) for invasive species management by overlapping habitat suitability, current known range, colonization fronts and areas...

Is autotoxicity responsible for inhibition growth of new conspecific seedlings under the canopy of the invasive Acacia dealbata Link? Gayana Botánica
Aguilera,Narciso; Guedes,Lubia M.; Becerra,José; González,Luis.
ABSTRACT Autotoxicity is a particular form of allelopathy and is suspected to be responsible for regulating intraspecific competition under the Acacia dealbata Link (Fabaceae) canopy. Was established a bioassay with controlled conditions following the natural patterns of plant material accumulation under the A. dealbata canopy to determine the effects of chemical compounds released by leaves, bark, flowers and pods of the invasive species on germination and early growth of conspecific seedlings. Morphological changes caused by A. dealbata plant parts in roots of A. dealbata seedlings grown in natural and controlled conditions were evaluated with scanning electron microscopy. The composition and behavior of the phytotoxicity of litter under the A. dealbata...

Invasive alien species management in Patagonia, Argentina: Prioritization, achievements and science-policy integration challenges identified by the National Parks Administration: Invasive alien species are a threat to biodiversity. Management options encompass prevention, early detection, eradication, control, exclusion and even"no action." More technical information is needed to achieve complex management actions successfully. In addition, managers and researchers address the problem with different approaches. Managers seek to prioritize management actions, and for researchers, these species are an opportunity to study basic and/or theoretical aspects, but not always applied to management. However, the management strategies offer a unique opportunity for...

New additions to the introduced flora of the Juan Fernández Islands: origin, distribution, life history traits, and potential of invasion RChHN
CUEVAS,JAIME G.; MARTICORENA,ALICIA; CAVIERES,LOHENGRIN A..
Oceanic islands, such as Juan Fernández in Chile, are the home for particular biotas that have evolved in isolation over a long period. The anthropogenic introduction of allochtonous plants is one of many problems for the conservation of endemic elements. In this paper, we present the new additions to the introduced flora of the Juan Fernández Islands, adding some comments about their life form, origin, morphological characteristics, ecology, distribution, abundance, and their potential of invasion. We cited 27 new species, 12 new genera, and three new families for the Juan Fernández flora (Amaryllidaceae, Commelinaceae and Violaceae). Most genera belonged to Asteraceae (seven species). Fifty-nine percent of taxa were perennial herbs, followed by annual or...

New insights about the introduction of the Portuguese oyster, Crassostrea angulata, into the North East Atlantic from Asia based on a highly polymorphic mitochondrial region ArchiMer
Grade, Ana; Chairi, Hicham; Lallias, Delphine; Power, Deborah M.; Ruano, Francisco; Leitao, Alexandra; Drago, Teresa; King, Jonathan W.; Boudry, Pierre; Batista, Frederico M..
It is commonly presumed that the Portuguese oyster Crassostrea angulata was introduced into the North East (NE) Atlantic from Asia. The analysis of the nucleotide sequence of a highly polymorphic non-coding mitochondrial region (major noncoding region - MNR) of C. angulata samples collected in Europe (Portugal), Africa (Morocco) and Asia (Shantou and Taiwan) provided new insight into the introduction of this species into the NE Atlantic. Sixty haplotypes and a nucleotide diversity of 0.0077 were observed in 130 analyzed sequences. Higher nucleotide diversity levels were observed in NE Atlantic sites than in Asian sites and significant genetic differentiation was found between the two. Our results suggest that C. angulata might have been introduced to the...

H.; Robbens, Johan; Stefanova, Kremena; Thibault, Delphine; Van Der Veer, Henk W.; Vansteenbrugge, Lies; Van Walraven, Lodewijk; Wozniczka, Adam.
Aim Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after the initial establishment of non‐native species remain largely unresolved, especially in marine systems. Ocean currents can be a major driver governing range occupancy, but this has not been accounted for in most invasion ecology studies so far. We investigate how well initial establishment areas are interconnected to later occupancy regions to test for the potential role of ocean currents driving secondary spread dynamics in order to infer invasion corridors and the source–sink dynamics of a non‐native holoplanktonic biological probe species on a continental scale. Location Western Eurasia. Time period 1980s–2016. Major taxa studied ‘Comb...
