A general eco-evolutionary framework for understanding bioinvasions Inra
Facon, B.; Genton, B.J.; Shykoff, J.; Jarne, P.; Estoup, A.; David, P..
Studies of bioinvasions have revealed various strategies of invasion, depending on the ecosystem invaded and the alien species concerned. Here, we consider how migration (as a demographic factor), as well as ecological and evolutionary changes, affect invasion success. We propose three main theoretical scenarios that depend on how these factors generate the match between an invader and its new environment. Our framework highlights the features that are common to, or differ among, observed invasion cases, and clarifies some general trends that have been previously highlighted in bioinvasions. We also suggest some new directions of research, such as the assessment of the time sequence of demographic, genetic and environmental changes, using detailed temporal...

Asymmetrical over-infection as a process of plant virus emergence Inra
Fabre, F.; Chadoeuf, J.; Costa, C.; Lecoq, H.; Desbiez, C..
Disentangling the role of epidemiological factors in plant pathogen emergences is a prerequisite to identify the most likely future invaders. An example of emergence was recently observed in France: in 10 years, “classic” (CL) strains of Watermelon mosaic virus (WMV) were displaced at a regional scale by newly introduced “emerging” (EM) strains. Here we analyse a 3 years dataset describing the co-dynamics of CL and EM strains at field scale using state-space models estimating jointly: (i) probabilities of primary and secondary infection and (ii) probabilities of over-infecting with a CL [EM] strain a plant already infected with an EM [CL] strain. Results especially indicate that it is more than 3 times less probable for a CL strain to over-infect an EM...

Behavioural flexibility and numerous potential sources of introduction for the sacred ibis: causes of concern in western Europe ? Inra
Clergeau, P.; Yésou, P..
In order to examine the dynamics and potential impact of the recently introduced sacred ibis Threskiornis aethiopicus, we review the published and unpublished data and report new information on its distribution in West European countries and particularly in France. This species, which escaped from zoos during the 1990s, is well established and has spread on the Atlantic coast and in Mediterranean region of France, with a mid-winter population reaching ca. 3200 individuals in winter 2004–2005 and ca. 1100 breeding pairs in spring 2005. The species has also escaped from zoological parks in Belgium, Germany, Spain, Italy and Portugal, and feral populations are established in Piedmont (Italy) and in the Canary Islands (Spain). The species dispersing ability...

Differences in life history strategies between an invasive and a competing resident seed predator Inra
Boivin, T.; Rouault, G.; Chalon, A.; Candau, J.N..
Competitive interactions may arise from biological invasion if a successful invasive species requires the ecological niche of a resident one. Life-history traits that make a species a successful invader are of particular interest in elucidating both invasion success and how interspecific competition may emerge. In southeastern France, the invasion of cedar forests by the seed chalcid Megastigmus schimitscheki generated competitive relationships with the resident M. pinsapinis for the exploitation of the seed resource. Among the numerous ecological traits allowing these seed predators to exploit their niche successfully, the timing of adult emergence, initial egg load and age-specific realized fecundities of females were investigated to help understanding...

Dispersal polymorphism in an invasive forest pest affects its ability to establish Inra
Robinet, C.; Liebhold, A..
Given the increasing number of biological invasions, there is a crucial need toidentify life history traits that promote invasion. Invasiveness reflects capabilities for both establishment after introduction and spread following establishment. In this paper, we explore, via simulation, the interacting effects of dispersal and Allee effects on both invasion processes. Dispersal capability is a trait that has been widely recognized to facilitate invasions. However, dispersal dilutes local population densities in isolated populations and this could strengthen Allee effects, ultimately promoting extinction of invading populations. A spatiallyexplicit, stochastic individual-based model was used to simulate dispersal, mating, and growth in isolated, newly...

Dispersion in time and space affect mating success and Allee effects in invading gypsy moth populations Inra
Robinet, C.; Lance, D.R.; Thorpe, K.W.; Onufrieva, K.S.; Tobin, P.C.; Liebhold, A.M..
1.Understanding why invading populations sometimes fail to establish is of considerable relevance to the development of strategies for managing biological invasions.2.Newly arriving populations tend to be sparse and are often influenced by Allee effects. Mating failure is a typical cause of Allee effects in low-density insect populations, and dispersion of individuals in space and time can exacerbate mate-location failure in invading populations.3. Here we evaluate the relative importance of dispersal and sexual asynchrony as contributors to Allee effects in invading populations by adopting as a case study the gypsy moth (Lymantria dispar L.), an important insect defoliator for which considerable demographic information is available.4. We used...

Forests of the past : a window to future changes Inra
Petit, R. J.; Hu, F. S.; Dick, C. W..
The study of past forest change provides a necessary historical context for evaluating the outcome of human-induced climate change and biological invasions. Retrospective analyses based on fossil and genetic data greatly advance our understanding of tree colonization, adaptation, and extinction in response to past climatic change. For instance, these analyses reveal cryptic refugia near or north of continental ice sheets, leading to reevaluation of postglacial tree migration rates. Species extinctions appear to have occurred primarily during periods of high climatic variability. Transoceanic dispersal and colonization in the tropics were widespread at geological time scales, inconsistent with the idea that tropical forests are particularly resistant to...

French attempts to eradicate non-indigenous mammals and their consequences for native biota Inra
Lorvelec, O.; Pascal, M..
Many European politicians, managers, and scientists believe that non-indigenous species cannot be eradicated and that attempts to do so are hazardous because of frequent undesirable results. This notion seems to be based on the view that successful eradications undertaken in many other parts of the world cannot be generalised. To allow reasoned consideration of this argument, the eradication of non-indigenous vertebrate species performed in the French territories (European and overseas) and their recorded consequences on native fauna and flora are synthesised. Nineteen vertebrate eradication attempts were recorded, with seven mammal species as the targets. Of these attempts four failed for technical reasons and one for reasons undetermined as yet. These...

Genetic structure and functioning of alien ship rat populations from a Corsican micro-insular complex Inra
Abdelkrim, J.; Pascal, M.; Samadi, S..
The detrimental effects of the introduced ship rat on bird species on the Lavezzi Mediterranean archipelago has led to the decision to eradicate the rodent from the main island, Lavezzu (73 ha), as well as from several neighbouring islets. A genetic study using eight microsatellite markers has revealed some of the dynamics of this rat population. First, it has been shown that the rat population was genetically stable (no departure from Hardy-Weinberg equilibrium and no linkage disequilibrium) and as suggested by paleontological data, established for a long time. This information is encouraging in term of viability of the eradication campaign in the long term, even if rare immigration events cannot be excluded. Second, this study shows that rats are likely...

Geographical range as predictor of spatial expansion of invading birds Inra
Croci, S.; Le Quilliec, P.; Clergeau, P..
Many studies have been carried out on predictive traits, such as geographical range, but most of them were related to introduced species and considered the invasion as a whole. The contrasting results previously obtained suggest that studies should take into account the dynamics of the invasion process (immigration, establishment, spread). We hypothesise that the geographical range reflects the species tolerance to new environments, and is related especially to the establishment and spread of the invasion process. First, data on spontaneous invasive birds in France since 1950 were collected to determine the relation between geographical range and spontaneous invasions of French biogeographical areas. Second, the urban context, assumed to be free of...

Holocene turnover of the french vertebrate fauna Inra
Pascal, M.; Lorvelec, O..
Comparing available paleontological, archaeological, historical, and former distributional data with current natural history and distributions demonstrated a turnover in the French vertebrate fauna during the Holocene (subdivided into seven sub-periods). To this end, a network of 53 specialists gleaned information from more than 1300 documents, the majority never cited before in the academic literature. The designation of 699 species as native, vanished, or non-indigenous in France or in one or more of its biogeographical entities during the Holocene period was investigated. Among these 699 species, 585 were found to belong to one or more of these categories. Among the 154 species that fit the definition of non-indigenous, 86 species were new species for...

Homogenization and influence of fragmentation in a biological invasion model Inra
El Smaily, M.; Hamel, F.; Roques, L..
In this paper, some properties of the minimal speeds of pulsating Fisher-KPP fronts in periodic environments are established. The limit ofthe speeds at the homogenization limit is proved rigorously. Near this limit,generically, the fronts move faster when the spatial period is enlarged, but thespeeds vary only at the second order. The dependence of the speeds on habitatfragmentation is also analyzed in the case of the patch model.

How can alien species inventories and interception data help us prevent insect invasions ? Inra
Kenis, M.; Rabitsch, W.; Auger-Rozenberg, M.A.; Roques, A..
Information relevant to invasion processes and invasive alien insect species management in Central Europe was extracted from two databases: a compilation of two inventories of alien insects in Austria and Switzerland, and a list of interceptions of non indigenous plant pests in Europe gathered by the European and Mediterranean PlantProtection Organisation (EPPO) for the period 1995-2004. For one third of the insects established in Switzerland and Austria, the region of origin is unclear. Others come mainly from North America, Asia and the Mediterranean region. Among the intercepted insects, 40% were associated with commodities from Asia, 32% from Europe and only 2% from North merica.Sternorrhyncha, Coleoptera and Psocoptera were particularly well...

Inferring introduction routes of invasive species using approximate Bayesian computation on microsatellite data Inra
Guillemaud, T.; Beaumont, M.A.; Ciosi, M.; Cornuet, J.M.; Estoup, A..
Determining the routes of introduction provides not only information about the history of an invasion process, but also information about the origin and construction of the genetic composition of the invading population. It remains difficult, however, to infer introduction routes from molecular data because of a lack of appropriate methods. We evaluate here the use of an approximate Bayesian computation (ABC) method for estimating the probabilities of introduction routes of invasive populations based on microsatellite data. We considered the crucial case of a single source population from which two invasive populations originated either serially from a single introduction event or from two independent introduction events. Using simulated datasets, we found...
