Testo completoAbstract (sommario):
A central and perhaps insurmountable challenge of invasion ecology is to predict which combinations of species and habitats most effectively promote and prevent biological invasions. Here, we integrate models of network structure and nonlinear population dynamics to search for potential generalities among trophic factors that may drive invasion success and failure. We simulate invasions where 100 different species attempt to invade 150 different food webs with 15–26 species and a wide range (0.06–0.32) of connectance. These simulations yield 11 438 invasion attempts by non-basal species, 47 per cent of which are successful. At the time of introduction, whether or not the invader is a generalist best predicts final invasion success; however, once the invader establishes itself, it is best distinguished from unsuccessful invaders by occupying a lower trophic position and being relatively invulnerable to predation. In general, variables that reflect the interaction between an invading species and its new community, such as generality and trophic position, best predict invasion success; however, for some trophic categories of invaders, fundamental species traits, such as having the centre of the feeding range low on the theoretical niche axis (for non-omnivorous and omnivorous herbivores), or the topology of the food web (for tertiary carnivores), best predict invasion success. Across all invasion scenarios, a discriminant analysis model predicted successful and failed invasions with 76.5 per cent accuracy for properties at the time of introduction or 100 per cent accuracy for properties at the time of establishment. More generally, our results suggest that tackling the challenge of predicting the properties of species and habitats that promote or inhibit invasions from food web perspective may aid ecologists in identifying rules that govern invasions in natural ecosystems.

Testo completoAbstract (sommario):
Species invasions represent a significant dimension of global change yet the dynamics of invasions remain poorly understood and are considered rather unpredictable. We explored interannual dynamics of the invasion process in the Eurasian collared dove ( Streptopelia decaocto ) and tested whether the advance of the invasion front of the species in North America relates to centrality (versus peripherality) within its estimated fundamental ecological niche. We used ecological niche modelling approaches to estimate the dimensions of the fundamental ecological niche on the Old World distribution of the species, and then transferred that model to the New World as measures of centrality versus peripherality within the niche for the species. Although our hypothesis was that the invasion front would advance faster over more favourable (i.e. more central) conditions, the reverse was the case: the invasion expanded faster in areas presenting less favourable (i.e. more peripheral) conditions for the species as it advanced across North America. This result offers a first view of a predictive approach to the dynamics of species' invasions, and thereby has relevant implications for the management of invasive species, as such a predictive understanding would allow better anticipation of coming steps and advances in the progress of invasions, important to designing and guiding effective remediation and mitigation efforts.

Testo completoAbstract (sommario):
Diversity–invasion resistance relationships are often variable and sensitive to environmental conditions such as resource availability. Resource stoichiometry, the relative concentration of different elements in the environment, has been shown to have strong effects on the physiology and interactions between different species. Yet, its role for diversity–invasion resistance relationships is still poorly understood. Here, we explored how the ratio of nitrogen (N) and phosphorus affects the productivity and invasion resistance of constructed microbial communities by a plant pathogenic bacterium, Ralstonia solanacearum . We found that resource stoichiometry and species identity effects affected the invasion resistance of communities. Both high N concentration and resident community diversity constrained invasions, and two resident species, in particular, had strong negative effects on the relative density of the invader and the resident community productivity. While resource stoichiometry did not affect the mean productivity of the resident community, it favoured the growth of two species that strongly constrained invasions turning the slope of productivity–invasion resistance relationship more negative. Together our findings suggest that alterations in resource stoichiometry can change the community resistance to invasions by having disproportionate effects on species growth, potentially explaining changes in microbial community composition under eutrophication.

Testo completoAbstract (sommario):
Dispersal polymorphism and mutation play significant roles during biological invasions, potentially leading to evolution and complex behaviour such as accelerating or decelerating invasion fronts. However, life-history theory predicts that reproductive fitness—another key determinant of invasion dynamics—may be lower for more dispersive strains. Here, we use a mathematical model to show that unexpected invasion dynamics emerge from the combination of heritable dispersal polymorphism, dispersal-fitness trade-offs, and mutation between strains. We show that the invasion dynamics are determined by the trade-off relationship between dispersal and population growth rates of the constituent strains. We find that invasion dynamics can be ‘anomalous’ (i.e. faster than any of the strains in isolation), but that the ultimate invasion speed is determined by the traits of, at most, two strains. The model is simple but generic, so we expect the predictions to apply to a wide range of ecological, evolutionary, or epidemiological invasions.

Testo completoAbstract (sommario):
Rewilding is a novel approach to ecological restoration. Trophic rewilding in particular aims to reinstate ecological functions, especially trophic interactions, through the introduction of animals. We consider the potential for trophic rewilding to address biological invasions. In this broad review, we note some of the important conceptual and ethical foundations of rewilding, including a focus on ecosystem function rather than composition, reliance on animal agency, and an appeal to an ethic of coexistence. Second, we use theory from invasion biology to highlight pathways by which rewilding might prevent or mitigate the impacts of an invasion, including increasing biotic resistance. Third, we use a series of case studies to illustrate how reintroductions can mitigate the impacts of invasions. These include reintroductions and positive management of carnivores and herbivores including European pine martens ( Martes martes ), Eurasian otters ( Lutra lutra ), dingoes ( Canis dingo ), Tasmanian devils ( Sarcophilus harrisii ) and tule elk ( Cervus canadensis nannodes ). Fourth, we consider the risk that rewilding may enable a biological invasion or aggravate its impacts. Lastly, we highlight lessons that rewilding science might take from invasion biology. This article is part of the theme issue ‘Trophic rewilding: consequences for ecosystems under global change’.

Testo completoAbstract (sommario):
Many biological invasions do not occur as a gradual expansion along a continuous front, but result from the expansion of satellite populations that become established at ‘invasion hubs’. Although theoretical studies indicate that targeting control efforts at invasion hubs can effectively contain the spread of invasions, few studies have demonstrated this in practice. In arid landscapes worldwide, humans have increased the availability of surface water by creating artificial water points (AWPs) such as troughs and dams for livestock. By experimentally excluding invasive cane toads ( Bufo marinus ) from AWP, we show that AWP provide a resource subsidy for non-arid-adapted toads and serve as dry season refuges and thus invasion hubs for cane toads in arid Australia. Using data on the distribution of permanent water in arid Australia and the dispersal potential of toads, we predict that systematically excluding toads from AWP would reduce the area of arid Australia across which toads are predicted to disperse and colonize under average climatic conditions by 38 per cent from 2 242 000 to 1 385 000 km 2 . Our study shows how human modification of hydrological regimes can create a network of invasion hubs that facilitates a biological invasion, and confirms that targeted control at invasion hubs can reduce landscape connectivity to contain the spread of an invasive vertebrate.

The progression of periodontal destruction is generally considered to be chronic in nature and slowly progressing. This study was to correlate radiographic examination with the clinical periodontal condition in cases of biologic width in subjects with healthy periodontium,generalized chronic periodontitis and generalized aggressive periodontitisclinically and radiographically. Subjects between the age group of 20 and 45 years were screened. About10 patients each with healthy periodontium,subjects with generalized chronic periodontitis and generalized aggressive periodontitis were selected.The 21 sites each with biologic width invasion were found in patients with the three groups.The mean biological widthper group was compared with the control group. Radiographs and clinical periodontal parameters were analyzed. Exploratory analysis and Spearman’s correlation were used to perform statistical analyses (SPSS p<0.05).Results showed a positive correlation between radiographic parameters of biologic width invasion and clinical conditions, with the mean clinical biological widthvalues in the healthy group being statistically greater than those in the groups 1 and 2.

Testo completoAbstract (sommario):
Le changement climatique et les invasions biologiques sont parmi les plus grandes menaces de la biodiversité et leurs impacts pourraient augmenter jusqu’à la fin du siècle. Parmi les espèces envahissantes, les fourmis sont un groupe particulièrement néfaste dû à leurs impacts sur les espèces natives, les processus écosystémique, la santé, l’agriculture et l’économie. L’objectif de cette thèse était de prédire les invasions de fourmis – en particulier avec le changement climatique qui pourrait favoriser les invasions en éliminant des barrières thermiques. J’ai utilisé trois approches complémentaires afin d’étudier le potentiel de différentes espèces à envahir : des modèles de distribution, des expériences comportementales et l’analyses d’une base de données de traits écologiques. J’ai modélisé l’aire favorable pour 15 espèces de fourmis parmi les pires, à la fois globalement, par continents, et dans les 34 hotspots de biodiversité. La distribution potentielle de seulement cinq espèce est prédite de diminuer (jusqu’à 35.8%) avec le changement climatique et l’aire potentielle diminue pour la plupart des espèces jusqu’à 63.2%. Les hotspots d’invasions de fourmis se situaient surtout dans des régions tropicales et subtropicales et ils correspondent particulièrement aux hotspots de biodiversité. Contrairement à ce qui est généralement admis, le changement climatique et les invasions biologiques n’agiront pas de manière synergique pour les fourmis. Par contre, les invasions de fourmis resteront probablement un problème global majeur, en particuliers dans les zones où les hotspots de biodiversité et les hotspots d’invasion se superposent. Les modèles de distribution ont identifié de larges zones de recouvrement entre aires favorables de plusieurs espèces de fourmis envahissantes. Dans le futur, ces espèces pourraient arriver simultanément dans les mêmes régions et entrer en compétition. Dans une série d’expériences, j’ai testé les différences comportementales entre 7 espèces de fourmis envahissantes (Anoplolepis gracilipes, Paratrechina longicornis, Myrmica rubra, Linepithema humile, Lasius neglectus, Wasmannia auropunctata et Pheidole megacephala). J’ai découvert deux stratégies comportementales différentes. Les interactions au niveau de la colonie ont suivi des processus démographiques plus complexes. De plus, j’ai mis au point deux expériences pour tester la capacité des fourmis envahissantes à explorer un nouvel espace et à exploiter des ressources. J’ai trouvé des différences significatives entre espèces et leur capacité à dominer par interférence comportementale était négativement corrélée à leurs capacités à découvrir et exploiter des ressources. Cette série d’expériences suggère que les ‘mécanismes’ d’invasion sont plus complexes que ce qui est généralement suggéré et que différentes espèces pourraient utiliser des stratégies comportementales différentes. Étant donné qu’il existe plus de 250 espèces de fourmis exotiques, il serait intéressant de pouvoir identifier à l’avance des futurs envahisseurs potentiels. Afin d’identifier des traits associés au caractère envahissant des fourmis, j’ai mis en place une base de données qui contient 2193 espèces de fourmis et 24 traits écologiques. J’ai effectué une analyse préliminaire de différences de traits entre fourmis natives et envahissantes qui a montré qu’il existe clairement des groupement distincts de natives et envahissantes, avec les espèces exotiques au milieu. Ces résultats pourraient servir de base pour construire un modèle prédictif des invasions de fourmis. Ces différentes approches (modèles, expériences, base de données) sont complémentaires car elles s’intéressent à des aspects différents du futur des invasions de fourmis qui sera vraisemblablement fortement influencé par le changement climatique. Le pires envahisseurs de demain ne seront probablement pas les même qu’aujourd’hui et les zones les plus à risque pourraient changer également<br>Climate change and biological invasions are both among the greatest threats to biodiversity and their impacts might increase by the end of the century. Among invasive species, ants are a prominent group due to their negative impacts on native species, ecosystem processes, human and animal health, agro-ecosystems and the economy. The objective of this thesis was to forecast future ant invasions – especially in the light of on-going climate change, which is generally thought to favour invasive species by removing thermal barriers. I used three complementary approaches to study the potential of different ant species to invade in the future: species distribution modelling, behavioural experiments and the analysis of a database of ecological traits. I modelled suitable area for 15 of the worst invasive ant species, both currently and with predicted climate change, globally, regionally and within the world’s 34 biodiversity hotspots. Surprisingly, the potential distribution of only five species was predicted to increase (up to 35.8%) with climate change, with most declining by up to 63.3%. The ant invasion hotspots are predominantly in tropical and subtropical regions of South America, Africa, Asia and Oceanic islands, and particularly correspond with biodiversity hotspots. Contrary to general expectations, climate change and biological invasions will not systematically act synergistically for ants. In addition, I found that the impacts of climate change can change over time and even reverse the trend of the impact (i.e., an increase instead of a decrease or vice versa). However, ant invasions will likely remain as a major global problem, especially where invasion hotspots coincide with biodiversity hotspots. The species distribution models have identified large potentially overlapping distributions of several invasive ants. In the future, these species may arrive simultaneously in the same regions and compete with each other. In a series of experiments, I tested behavioural differences among 7 highly invasive ant species (Anoplolepis gracilipes, Paratrechina longicornis, Myrmica rubra, Linepithema humile, Lasius neglectus, Wasmannia auropunctata and Pheidole megacephala). I discovered two different behavioural strategies among invasive ants. Interactions at the colony level, exhibited more complex demographic processes and more variability. Further, I investigated resource competition and differences in resource exploitation. I found significant differences among species, with competitive abilities that were negatively correlated with behavioural dominance. This series of experiments suggests that the ‘mechanisms’ of invasiveness are more complex than previously thought and that different invasive ant species may use different behavioural strategies. Since there are more than 250 exotic species of ants, it would be interesting to identify potential future invaders. In order to identify traits associated with invasiveness in ants, I set up a database with 2193 ant species and 24 ecological characteristics. I performed a preliminary analysis of trait differences between native and invasive ants that shows clearly different clusters of invasive and native species, with exotic species in between. These results could be used as a basis to construct a predictive model of future ant invasions. The different methods used (models, experiments, database) are complementary in that they explore different aspects of the future ant invasions which are likely to be influenced by on-going climate change. The worst invaders of tomorrow may not be the same as today and similarly, areas most at risk are likely to change

La lutte biologique est souvent présentée comme une méthode de lutte contre les ravageurs respectueuse de l'environnement, même si la lutte par acclimatation (introduction d'une espèce exotique) peut être à l'origine d'invasion biologique.

L'objectif principal de cette thèse est d'améliorer notre connaissance des processus évolutifs pouvant accompagner l'élevage en captivité, ainsi que ceux qui sont liés aux invasions biologiques.

Les résultats obtenus montrent que les changements évolutifs les plus importants concernent le compartiment de lutte biologique par rapport aux compartiments sauvages (natifs et envahissants). Ce compartiment a subi des changements phénotypiques remarquables en réponse aux conditions d'élevage en laboratoire. Les changements évolutifs les plus spectaculaires concernent différents traits liés à la reproduction. Par exemple, les femelles de lutte biologique se reproduisent plus tôt, ont une fécondité journalière plus élevée, ainsi qu'une longévité et une durée de vie reproductive plus courte. Nous avons également mis en évidence des changements évolutifs entre des populations sauvages natives et envahissantes.

This species is now considered as invasive, and can have harmful effects on the environment. The main objective of this thesis is to better understand the impact of mass rearing on life-history traits, with a focus on traits that may be associated with invasion success. To do so, experimental approaches were carried out to monitor changes in life-history traits for three types of populations (biocontrol, native or invasive). The corresponding results indicate that the most important evolutionary changes occur in the biocontrol populations (by contrast with the invasive and native populations). Mass rearing appears to induce significant phenotypic changes in the biocontrol populations, with the most spectacular changes being related to reproductive life-history traits. For instance, biocontrol females reproduce significantly earlier, have a higher daily fecundity, but also exhibit lower life expectancy and lower reproductive lifespan. We also evidence other differences between the native and invasive populations. Cold tolerance and pathogen resistance are also lower in biocontrol populations than in wild populations. Altogether, our findings indicate that adaptations to mass rearing conditions may affect the fitness of H. axyridis populations in natural environments. This suggests that, even if the European biocontrol strain is unable to successfully colonize a natural environment, it may nonetheless impact the invasion dynamics of the species in Europe thanks to the admixture with the invasive American population

Testo completoAbstract (sommario):
Les invasions biologiques constituent aujourd'hui une source d'inquiétude du fait de leur nette augmentation et des conséquences écologiques, économiques et sanitaires dont elles sont à l'origine. Pour qu'une population devienne envahissante, il faut (i) qu'elle soit introduite, (ii) qu'elle s'établisse et (iii) qu'elle prolifère. Chacune de ces trois étapes constitue un défi difficile à relever, et les processus en jeu sont encore mal connus. Cette thèse décrit un ensemble de recherches visant à comprendre l'invasion mondiale particulièrement réussie de la coccinelle asiatique Harmonia axyridis. Nous avons dans un premier temps étudié l'étape d'introduction en retraçant les routes d'invasion d'H. axyridis à l'aide de marqueurs microsatellites et de la méthode ABC (Approximate Bayesian Computation). Nous avons montré que la population envahissante la plus ancienne dans le nord-est américain avait été la tête de pont de l'invasion mondiale en devenant la source des foyers européen, sud-américain et africain. En Europe, on constate également une hybridation avec une souche de lutte biologique. Dans un deuxième temps, nous avons exploré l'étape d'établissement de l'espèce. Nous avons montré que les populations envahissantes d'H. axyridis avaient subi une purge génétique réduisant considérablement les effets associés à la dépression de consanguinité. Par ailleurs, l'événement d'hybridation en Europe apporte des avantages phénotypiques probables à cette population envahissante. Nous avons ensuite étudié plusieurs aspects de l'étape de prolifération. Nous avons montré que les populations européennes avaient évolué vers de plus fortes capacités de dispersion sur le front d'invasion. Par ailleurs, nos résultats montrent que la commercialisation en France d'une souche non-volante de lutte biologique a pu avoir des conséquences positives sur l'expansion de la population envahissante par des phénomènes d'hétérosis ou d'augmentation de variance génétique. Enfin, nous discutons de l'importance d'étudier de manière approfondie une espèce modèle telle qu'H. axyridis pour améliorer nos connaissances générales sur les mécanismes éco-évolutifs impliqués lors des invasions biologiques<br>Biological invasions are a concern because of their increase and their environmental, economic and human health consequences. To become invasive, a population must (i) be introduced, (ii) established itself and (iii) proliferates. Each of these three steps constitutes a challenge, and the processes involved are still poorly understood. This thesis describes a set of research actions which aims at understanding the worldwide successful invasion of the Asian ladybird Harmonia axyridis.We first investigated the introduction step by retracing invasion routes of H. axyridis using microsatellite markers and the ABC (Approximate Bayesian Computation) method. We have shown that the oldest invasive population in the eastern North America acted as a bridgehead of the worldwide invasion by becoming the source of the European, the South American and the African outbreaks. We also found evidence for a genetic admixture event in Europe with a biological control strain.Second, we explored the establishment step. We have shown that invasive populations of H. axyridis endured a genetic purge which significantly reduced adverse effects associated with inbreeding depression. In addition, the admixture event in Europe likely brought phenotypic benefits to this invasive population.We then studied several aspects of the proliferation step. We found that European populations had evolved towards higher dispersal abilities on the invasion front. Moreover, our results show that the use of a flightless biocontrol strain which is still sold in France may have a positive impact on the expansion of the invasive population through heterosis or increased of genetic variance.Finally, we discuss the importance of studying in detail a model species such as H. axyridis to improve our general understanding of the eco-evolutionary mechanisms involved in biological invasions

Invasive species represent a major challenge through their consequences on<p>biodiversity, human health and economy. Their effects are especially important on fragile and<p>unique insular biotas such as the Galápagos Islands. Ants in particular are keystone species<p>implicated in ecosystem functioning and biodiversity and they can be dramatic invaders. In<p>the Galápagos Islands, the tropical fire ant Solenopsis geminata is considered a high-impact<p>invasive species, though it remains surprisingly poorly studied. The objectives of this work<p>are to document the invasion of S. geminata in the Galápagos Islands by 1) updating its<p>distribution; 2) determining its reproduction and dispersal strategies and reconstruct its<p>invasion history throughout the archipelago and 3) evaluating its impact on the native fauna<p>(focusing on ants and arthropods communities and endemic land tortoises).<p>First, we added 66 new records of S. geminata in the Galápagos since 2008. It has<p>now been recorded on seven islands and 11 islets in a wide range of habitats, including<p>nesting sites of 24 endemic and/or endangered vertebrate species, for which it constitutes a<p>potential threat.<p>Secondly, by combining Bayesian clustering methods, coalescent-based scenario<p>testing using microsatellite data and historical records, we determined that genetic diversity<p>of populations of S. geminata collected in Galápagos Islands is significantly lower than the<p>genetic diversity of populations from native areas (Costa Rica). The Galápagos populations<p>form three clusters corresponding to an island or groups of islands. They appear to be the<p>result of a single introduction in the first half of the 19th century, probably from mainland<p>Ecuador, which acted as a bridgehead population to two subsequent introductions within the<p>archipelago, corresponding human colonization fluxes in the archipelago.<p>We sampled ants in all main habitats of Santa Cruz Island. Introduced ant species<p>were largely prevalent, and S. geminata was the dominant species and was associated with<p>low evenness of ant communties and lower abundance of native ants. We found that<p>Galápagos’ ant communities are determined by the vegetation type and altitude, but found<p>only little evidence for competitively structured assemblages, except in disturbed areas.<p>The arthropod diversity was investigated in two agricultural sites of Santa Cruz Island<p>by combining three complementary sampling techniques. More than half of the species were<p>either endemic or native, but introduced species constituted the majority of the catches.<p>Solenopsis geminata was by far the most abundant and common species.<p>Finally, we investigated the mortality of Cheloidis land tortoise’s eggs and hatchlings<p>in an area infested by S. geminata on Santa Cruz Island with regard to the abundance of fire<p>ants and the duration of incubation. Egg survival was negatively associated with longer incubation times but we found no direct relation between ant density and tortoise mortality<p>despite a high abundances of fire ants in the vicinity of the majority of the tortoise burrows.<p>Our work allows addressing ecological and genetical aspects of the invasion of S.<p>geminata in the Galápagos Islands. We analyzed our results in the light of an ecoevolutionary<p>framework presenting different invasion scenarios and discussed S. geminata<p>as an invasive ant. This provided us with information useful for the study and management of<p>this invasive species in the Galápagos Islands.<p>/<p>Les espèces invasives constituent un défi majeur à cause de leur impact sur la<p>biodiversité, la santé humaine et l’économie. Leurs effets sont particulièrement importants<p>sur les environnements insulaires fragiles et uniques comme les île Galápagos. Les fourmis<p>en particulièr sont des espèces clé de voûte du fonctionnement des écosystèmes et de la<p>biodiversité. Elles peuvent de ce fait devenir des envahisseurs spectaculaires. Dans les îles<p>Galápagos, la fourmi de feu tropicale Solenopsis geminata fait partie des espèces invasives<p>à haut impact et cependant elle a été étonnamment peu étudiée. Les objectifs de ce travail<p>consistent à documenter l’invasion de S. geminata dans l’archipel des Galápagos: 1) en<p>mettant à jour sa distribution; 2) en déterminant ses stratégies de reproduction et de<p>dispersion et en reconstruisant l’histoire de son invasion dans l’archipel et 3) en évaluant son<p>impact sur la faune native (particulièrement sur les communautés de fourmis et<p>d’arthropodes et sur les tortues terrestres endémiques).<p>Tout d’abord, nous avons ajouté 66 nouveaux relevés de S.geminata aux Galápagos<p>depuis 2008. À ce jour, la fourmi a été observée sur 7 îles et 11 îlots, et ce dans une grande<p>variété d’habitats. On la trouve également sur les sites de ponte de 24 espèces de vertébrés<p>endémiques ou en voie de disparition, qu’elle menace ainsi potentiellement.<p>Ensuite, en combinant des méthodes bayésiennes de regroupement et des<p>comparaisons de scénarios en se basant sur des séquences microsatellites et des données<p>historiques, nous avons montré que la diversité génétique des populations de S. geminata<p>des Galápagos est significativement inférieure à celle des populations des zones d’indigénat<p>(Costa Rica). Les populations des Galápagos - réparties en 3 groupes correspondant à une<p>île ou un groupe d’îles – sont le résultat d’une introduction unique ayant eu lieu dans la<p>première moitié du 19ème siècle. Elles proviennent vraisemblablement de l’Equateur<p>continental et constituent une population “tête de pont” pour deux introductions ultérieures au<p>sein de l’archipel. Ces mouvements correspondent aux flux de populations humaines.<p>Nous avons échantillonné les fourmis dans tous les principaux habitats de l’île de<p>Santa Cruz. Les fourmis introduites sont largement prévalentes. Solenopsis geminata<p>constitue l’espèce dominante et se trouve associée avec une faible équitabilité des<p>communautés de fourmis ainsi qu’avec une diminution de l’abondance des fourmis natives.<p>Nos résultats indiquent que les communautés de fourmis des Galápagos sont structurées<p>par le type de végétation et l’altitude, alors que les assemblages de fourmis ne sont pas<p>structurés compétitivement, à l’exception des zones perturbées.<p>Nous avons investigué la diversité arthropodienne de deux sites agricoles de l’île de<p>Santa Cruz en combinant trois méthodes d’échantillonnage complémentaires. Plus de la moitié des espèces collectées étaient soit endémiques, soit natives. Les espèces introduites<p>ont toutefois constitué la majorité des individus collectés. Solenopsis geminata était de loin la<p>plus abondante et la plus commune des espèces récoltées.<p>Enfin, dans une zones infestées par S. geminata sur l’île de Santa Cruz, nous avons<p>mis en relation la mortalité des oeufs et juvéniles de tortues terrestres Chelonoidis avec<p>l’abondance des fourmis de feu et la durée d’incubation des oeufs. Le taux de survie des<p>oeufs est négativement corrélé à leur durée d’incubation. Cependant, malgré de très hautes<p>abondances de fourmis de feu à proximité des nids de tortues, nous n’avons pas trouvé de<p>relation directe avec leur mortalité.<p>Pour conclure, ce travail aborde les aspects génétiques et écologiques de l’invasion<p>de la fourmi de feu tropicale dans les îles Galápagos. Nos résultats sont analysés au sein<p>d’un cadre éco-évolutif présentant différents scénarios d’invasion. Nous discutons également<p>de S. geminata en tant qu’espèce invasive. Nous espérons apporter des informations utiles<p>dans le cadre de l’étude et du contrôle de cette espèce invasive aux Galápagos.<br>Doctorat en Sciences<br>info:eu-repo/semantics/nonPublished

Les invasions biologiques représentent l’un des composants majeurs du changement global en cours. Pourtant, notre connaissance des processus évolutifs et écologiques liés aux invasions biologiques reste encore limitée. Cette thèse a pour objectif d’améliorer notre connaissance sur ces processus au travers de l’étude d’une fourmi envahissante, Wasmannia auropunctata. Dans ce but, nous avons étudié les caractéristiques génétiques et comportementales de différentes populations de l’aire native ou introduite et les propriétés de leur habitat, et conduit des études expérimentales en milieu contrôlé. Nos résultats mettent en évidence un polymorphisme du système de reproduction (clonal/sexué) chez W. Auropunctata. Contrairement aux attendus issus de la littérature, le caractère envahissant de certaines populations émerge dans l’aire native de l’espèce, et ne s’explique ni par leur système de reproduction, ni par leur organisation sociale, mais plutôt par une modification des milieux liée à l’activité humaine. Le système de reproduction clonal semble néanmoins jouer un rôle indirect dans le succès envahissant de l’espèce en maintenant des combinaisons de gènes permettant d’occuper les habitats anthropisés. Une expérience en conditions contrôlées confirme que les ouvrières des nids clonaux sont plus tolérantes que les ouvrières des nids sexués aux conditions abiotiques chaudes et sèches observées dans les zones anthropisées de l’aire native. Notre étude souligne l’importance des processus éco-évolutifs ayant lieu au sein de l’aire native des espèces envahissantes, le rôle majeur de l’homme dans ces processus, et le potentiel adaptatif de la reproduction clonale.

Testo completoAbstract (sommario):
Abstract This 381-paged book covers the biology, ecology, impact and management of 34 common alien invasive species, with reviews on the history and context of avian introductions and invasions in five major regions (Oceania, Africa, Europe (including the Middle East, Asia and South America)), as well as management challenges and the potential of citizen science for monitoring alien birds. The book pitches at the introductory level and is ideal for readers to gain a quick and comprehensive view of the current status of global avian invasions. It has brought the records and research of avian invasion one step ahead of other alien invasive animal taxa. Many chapters contain distribution maps and data tables on the diet and morphology of the species, providing a good reference for the species and its management issues. Each chapter also contains a rich list of references that could help readers dive further into the topic.

AbstractMuch of the literature dealing with the biology and management of invasive species has focused on the damaging ecological and economic consequences of invasions (see Chaps. 10.1007/978-3-030-45367-1_2, 10.1007/978-3-030-45367-1_3, and 10.1007/978-3-030-45367-1_14 of this volume for review). In this chapter, we shift the focus to the causes of invasion, with the goal of proactively limiting or preventing invasions rather than reacting to them once they have occurred. Preventing the introduction of invasive species is one key element in this proactive approach (Chap. 10.1007/978-3-030-45367-1_6, this volume). Here, we specifically focus on ecosystem attributes that affect whether or not an ecosystem is vulnerable to invasion, that is, the features that affect its invasibility (Lonsdale 1999), with particular emphasis on the role of natural and anthropogenic disturbance.

Testo completoAbstract (sommario):
Abstract Diverse biotic interactions between non-native plant species and other species from all taxonomic groups are crucial mediators of the dynamics of plant invasions. This chapter reviews the key hypotheses in invasion ecology that invoke biotic interactions to explain aspects of plant invasion dynamics. We examine the historical context of these hypotheses and assess the evidence for accepting or rejecting their predictions. Most hypotheses invoke antagonistic interactions, mainly competition, predation, herbivory interactions and the role of pathogens. Only in the last two decades have positive (facilitative/mutualistic) interactions been explicitly included in invasion biology theory (as in ecological theory in general). Much information has accumulated in testing hypotheses relating to biotic resistance and Enemy Release Theory, although many of the emerging generalizations are still contentious. There is growing consensus that other drivers of plant invasion success, such as propagule pressure and disturbance, mediate the outcome of biotic interactions, thereby complicating our ability to make predictions, but these have rarely been assessed in both native and adventive ranges of non-native invasive species. It is also widely acknowledged that biogeographic comparisons, more than common garden experiments, are needed to shed light on many of the contradictory results. Contrasting findings have also emerged in exploring the roles of positive interactions. Despite strong evidence that such interactions are crucial in many communities, more work is needed to elucidate the factors that influence the relative importance of positive and negative interactions in different ecosystems. Different types of evidence in support of invasional meltdown have emerged for diverse habitats and across spatial scales. In light of increasing evidence that biotic indirect effects are crucial determinants of the structure, dynamics and evolution of ecological communities, both direct and indirect interactions involving native and non-native species must be considered to determine how they shape plant invasion patterns and the ecological impacts of non-native species on recipient communities. Research that examines both biotic interactions and the factors that mediate their strength and alter interaction outcomes is needed to improve our ability to predict the effects of novel interactions between native and non-native species, and to envisage how existing invaded communities will respond to changing environmental conditions. Many opportunities exist for manipulating biotic interactions as part of integrated control strategies to reduce the extent, density and impacts of non-native plant invasions. These include the introduction of species from the native range of the non-native plant for biological control, diverse manipulations of plant - herbivore interactions and many types of interaction to enhance biotic resistance and steer vegetation recovery following non-native plant control.

Testo completoAbstract (sommario):
Abstract Invasive plants often occur at high densities and tend to be highly generalist in their interactions with herbivores, pathogens, mycorrhiza, endophytes and pollinators. These characteristics mean that invasive plants should frequently participate in diverse indirect biotic interactions with the surrounding community, mediated by their direct interaction partners (e.g. antagonists and mutualists). Indirect interactions play an important role in many ecological processes, yet we still lack a systematic understanding of the circumstances under which they influence the success and impacts of invasive species. In this chapter, I first describe several of the indirect interaction pathways that are commonly encountered in invasion biology and review their contribution to the impacts of plant invasions on co-occurring species. The literature review revealed that there are now many case studies describing various indirect impacts of invasive plants. However, identical interaction motifs (e.g. plant-enemy-plant, plant-mutualist-plant) can bring about several possible outcomes, depending upon each species' provenance, relative abundances and interaction strengths, abiotic resource availability, spatial and temporal scale and the influence of other species. Moreover, knowledge gaps identified include a lack of studies of indirect facilitation outside of plant-pollinator systems, limited consideration of indirect invader impacts on other non-native species, and the scarcity of generalizable results to date. Second, I integrate the literature with some trending research areas in invasion biology (interaction networks, biogeography, invasion dynamics) and identify some potential future research directions. Finally, I discuss how knowledge about indirect biotic interactions could be incorporated into the management of invasive plants.

Testo completoAbstract (sommario):
Abstract The introduction of species to new locations leads to novel competitive interactions between resident native and newly-arriving non-native species. The nature of these competitive interactions can influence the suitability of the environment for the survival, reproduction and spread of non-native plant species, and the impact those species have on native plant communities. Indeed, the large literature on competition among plants reflects its importance in shaping the composition of plant communities, including the invasion success of non-native species. While competition and invasion theory have historically developed in parallel, the increasing recognition of the synergism between the two themes has led to new insights into how non-native plant species invade native plant communities, and the impacts they have on those plant communities. This chapter provides an entry point into the aspects of competition theory that can help explain the success, dominance and impacts of invasive species. It focuses on resource competition, which arises wherever the resources necessary for establishment, survival, reproduction and spread are in limited supply. It highlights key hypotheses developed in invasion biology that relate to ideas of competition, outlines biotic and abiotic factors that influence the strength of competition and species' relative competitive abilities, and describes when and how competition between non-native and native plant species can influence invasion outcomes. Understanding the processes that influence the strength of competition between non-native and native plant species is a necessary step towards understanding the causes and consequences of biological invasions.

Testo completoAbstract (sommario):
Abstract In 1999, Daniel Simberloff and Betsy Von Holle introduced the term 'invasional meltdown'. The term and the concept have been embraced and critiqued but have taken a firm hold within the invasion biology canon. The original formulation of the concept argued two key points: first, biologists rarely study how non-natives interact with one another. Second, nearly all the conceptual models about the success and impact of invasive species are predicated on the importance of competitive interactions and an implicit assumption that non-natives should interfere with establishment, spread and impact of other non-natives. In response, Simberloff and Von Holle called for more research on invader interactions and proposed an alternative consequence of non-native species interactions - invasional meltdown - where facilitative interactions among non-natives could increase the invasion rate or ecological impacts in invaded systems. This chapter outlines the primary pathways in which direct and indirect interactions among non-natives could lead to invasional meltdown. It provides examples of how different types of interactions among non-natives could lead to net positive effects on the invasion success of non-native plants or the impact of non-native plants on invaded ecosystems. Direct effects are by far the most commonly explored form of non-native- non- native interaction, primarily focusing on plant mutualisms with pollinators, seed dispersers or soil microbial mutualists. There are, however, also examples of non-native plants that benefit from commensal and even herbivorous interactions with other non-natives. Indirect interactions among non-natives are very infrequently studied. Although examples are scarce, non-natives may indirectly benefit other non-native plants through trophic cascades, apparent competition and indirect mutualisms. It remains unclear whether indirect effects are important pathways to invasional meltdown. More work is needed on studying ecosystems that are invaded by multiple non-native species and we need to consider the full range of interactions among non-natives that could either stymie or promote their spread, population growth and impact. Only then can we address how common facilitative interactions are relative to competitive interactions among non-natives or provide robust suggestions on how to manage ecosystems.
