Titre : The invasive herb Lupinus polyphyllus can reduce plant species richness independently of local invasion age Type de document : Imprimé Auteurs : Marju Prass ; Satu Ramula ; Miia Jauni ; D. Johan Kotze Année de publication : 2022 Article en page(s) : 425-436 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : The ecological impacts of invasive species may change or accumulate with time since local invasion, potentially inducing further changes in communities and the abiotic environment. Yet, time since invasion is rarely considered when investigating the ecological impacts of invasive non-native species. To examine the effect of time since invasion on the ecological impacts of Lupinus polyphyllus, a perennial nitrogen-fixing herb, we surveyed vascular plant communities in the presence and absence of L. polyphyllus in young, intermediate, and old semi-natural grassland sites (ca. 5, 10, 15 years representing both time since lupine invasion and plant community age). We analyzed vascular plant community composition, vascular plant species richness, and the cover of various ecological plant groups and L. polyphyllus. In contrast to our hypotheses, we found no change in the mean cover of L. polyphyllus (about 35%) with time since local invasion, and an ordination did not suggest marked changes in plant community composition. L. polyphyllus was associated with lower species richness in invaded plant communities but this effect did not change with time since invasion. Invaded plant communities were also associated with lower occurrence of generalist, oligotrophic (low-nutrient-adapted) and copiotrophic (nutrient-demanding) species but no temporal dynamics were detected. We conclude that even the intermediate cover of L. polyphyllus can reduce plant species richness, but the ecological impact caused by this invader might not dramatically change or accumulate with time since invasion.

Titre : Comparing common fountain grass removal techniques: cost efficacy and response of native plant community Type de document : Imprimé Auteurs : Helen I. Rowe ; Tiffany A. Sprague ; Paul Staker Année de publication : 2022 Article en page(s) : 3817-3830 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Pennisetum setaceum (Forssk.) Chiov., 1923 Résumé : Fountain grass (Pennisetum setaceum) is a globally pervasive invasive species and a prime example of an escaped horticultural ornamental. In areas where it is not naturally found, it displaces native plant communities and disrupts ecological systems and processes. Cost-effective removal efforts that protect the native plant community are needed for its control. We conducted an experiment from March 2018 to March 2021 in 5 m × 5 m plots to test the efficacy and record costs for common removal techniques (cut and herbicide, herbicide one or two times per year, manual removal) in the Sonoran Desert, Arizona, United States. Each treatment took 2.5 years to achieve control in the plots, and treatments did not negatively affect the native plant community. The response of native plants was mediated by year, such that native cover in treatment plots recovered to similar levels as uninvaded control plots with sufficient rainfall. Plots that received the manual removal treatment had almost five more native plant species than the invaded control treatment (22.7 ± 1.63 compared to 18.1 ± 1.61). Herbicide applied in spring and fall increased efficacy of removals in the first year but was not significantly different from the other treatments averaged over year. Herbicide once per year was most cost effective across different sized areas. Manual removal was also cost effective in small areas (< 0.06 hectares) but was more expensive than herbicide twice a year in larger areas. Our results provide a toolset that enables managers to select removal treatments based on a balance of convenience, resources, and scale of the infestation.

Titre : The nature of economic costs of biological invasions Type de document : Imprimé Auteurs : Anne-Charlotte Vaissière ; Pierre Courtois ; Franck Courchamp ; Melina Kourantidou ; Christophe Diagne ; Franz Essl (1973-) ; Natalia Kirichenko ; Mélissa Welsh ; Jean-Michel Salles Année de publication : 2022 Article en page(s) : 2081-2101 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : The management of invasive alien species (IAS) is complex and requires consideration of intertwined ecological and economic dimensions. Given the wide variety of costing purposes and practices, and the associated risk of misunderstandings and/or miscommunication which may jeopardize perceptions and management, there is an urgent need to disentangle the nature of IAS costs. We provide a synthesis of the nature and diversity of the economic costs associated with IAS and the potential limits of their assessment. This work promotes a common understanding of costs of IAS across disciplines, which is essential for improving the estimation, interpretation, selection, and uptake of costs when designing IAS management policies or raising societal awareness of their threats. Our study contributes to a clearer understanding of the nature of costs, serving as a sound basis for managing biological invasions.

Titre : Invasive alien species as simultaneous benefits and burdens: trends, stakeholder perceptions and management Type de document : Imprimé Auteurs : Melina Kourantidou ; Phillip J. Haubrock ; Ross N. Cuthbert ; Thomas W. Bodey ; Bernd Lenzner ; Rodolphe E. Gozlan ; Martin A. Nuñez ; Jean-Michel Salles ; Christophe Diagne ; Franck Courchamp Année de publication : 2022 Article en page(s) : 1905-1926 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : In addition to being a major threat to biodiversity and ecosystem functioning, biological invasions also have profound impacts on economies and human wellbeing. However, the threats posed by invasive species often do not receive adequate attention and lack targeted management. In part, this may result from different or even ambivalent perceptions of invasive species which have a dual effect for stakeholders—being simultaneously a benefit and a burden. For these species, literature that synthesizes best practice is very limited, and analyses providing a comprehensive understanding of their economics are generally lacking. This has resulted in a critical gap in our understanding of the underlying trade-offs surrounding management efforts and approaches. Here, we explore qualitative trends in the literature for invasive species with dual effects, drawing from both the recently compiled InvaCost database and international case studies. The few invasive species with dual roles in InvaCost provide evidence for a temporal increase in reporting of costs, but with benefits relatively sporadically reported alongside costs. We discuss methods, management, assessment and policy frameworks dedicated to these species, along with lessons learned, complexities and persisting knowledge gaps. Our analysis points at the need to enhance scientific understanding of those species through inter- and cross-disciplinary efforts that can help advance their management.

Titre : Introduction pathways of economically costly invasive alien species Type de document : Imprimé Auteurs : Anna J. Turbelin ; Christophe Diagne ; Emma J. Hudgins ; D. J. Moodley ; Melina Kourantidou ; Ana Novoa ; Phillip J. Haubrock ; Camille Bernery ; Rodolphe E. Gozlan ; Robert A. Francis ; Franck Courchamp Année de publication : 2022 Article en page(s) : 2061–2079 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Introduction pathways InvaCost Invasive alien species Monetary impact Exotic mammals Non-native insects Management Policy Résumé : Introduction pathways play a pivotal role in the success of Invasive Alien Species (IAS)—the subset of alien species that have a negative environmental and/or socio-economic impact. Pathways refer to the fundamental processes that leads to the introduction of a species from one geographical location to another—marking the beginning of all alien species invasions. Increased knowledge of pathways is essential to help reduce the number of introductions and impacts of IAS and ultimately improve their management. Here we use the InvaCost database, a comprehensive repository on the global monetary impacts of IAS, combined with pathway data classified using the Convention on Biological Diversity (CBD) hierarchical classification and compiled from CABI Invasive Species Compendium, the Global Invasive Species Database (GISD) and the published literature to address five key points. Data were available for 478 individual IAS. For these, we found that both the total and annual average cost per species introduced through the ‘Stowaway’ (US US$89.4m) and ‘Contaminant’ pathways (US US$158.0m) were higher than species introduced primarily through the ‘Escape’ (US US$25.4m) and ‘Release’ pathways (US US$16.4m). Second, the recorded costs (both total and average) of species introduced unintentionally was higher than that from species introduced intentionally. Third, insects and mammals, respectively, accounted for the greatest proportion of the total cost of species introduced unintentionally and intentionally respectively, at least of the available records; ‘Stowaway’ had the highest recorded costs in Asia, Central America, North America and Diverse/Unspecified regions. Fourthly, the total cost of a species in a given location is not related to the year of first record of introduction, but time gaps might blur the true pattern. Finally, the total and average cost of IAS were not related to their number of introduction pathways. Although our findings are directly limited by the available data, they provide important material which can contribute to pathway priority measures, notably by complementing studies on pathways associated with ecologically harmful IAS. They also highlight the crucial need to fill the remaining data gaps—something that will be critical in prioritising limited management budgets to combat the current acceleration of species invasions.
