Our understanding of the role of information sources in stakeholders’ IAS management is elusive for the majority of insect invaders. We focused on the fall armyworm (FAW), <i>Spodoptera frugiperda</i>, one of the most damaging alien insects worldwide, to explore the role of information sources in farmers’ management of alien agricultural pests. We developed a theoretical framework containing three components and seven indicators, conducted extensive household questionnaires in the region bordering Myanmar, Laos, and Vietnam in southwestern China, and used quantitative descriptions, ordinal logistic regressions, and Mann–Whitney U-tests in statistical analyses. Our results showed that farmers had a generally low level of recognition ability, medium level of control ability, and high level of engagement initiative in FAW management, and farmers’ FAW management was significantly associated with socio-demographic variables. Farmers obtained FAW-relevant information from four sources with a high preference for training workshops and agricultural retail stores; further, training workshops played a more effective role than agricultural retail stores in farmers’ FAW management. Here, we show for the first time that training workshops are the most effective sources of information in farmers’ FAW management, and agricultural retail stores serve as necessary support. Future research could extend these conclusions by including socioeconomic mechanisms such as informational feedback loops and public-private partnerships among stakeholders. Our findings contribute to theoretical insights into the role of information sources in IAS control, and to optimized management of alien agricultural pests.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"256 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examined the changes in the fish community within the Kerkini Reservoir, a Ramsar Site in Greece, influenced by the establishment of invasive fish species. Through standardized seasonal surveys conducted in 2007–2008 and 2023, we assessed changes in fish species composition, abundance, and functional traits. Our findings revealed a shift in dominance, with invasive species such as <i>Gymnocephalus cernua</i> emerging as key players in the reservoir's fish fauna. Moreover, high numbers of fish specimens and biomass were recorded, highlighting the reservoir’s high productivity. However, concerns arise regarding the ecological impacts of invasive species, particularly <i>G. cernua</i>, which exhibits traits associated with ecological disruption and competition with native species. A shift towards the dominance of species with shorter lifespans, smaller sizes and lower trophic levels was observed. In addition, the observed decline in native species abundance, coupled with poor ecological quality assessments, underscores the need for proactive management measures to preserve ecosystem integrity. This study contributes valuable insights into the ecological dynamics of a system considered a biodiversity hotspot. It also highlights the proliferation of invasive fish species as a primary driver and underscores the importance of ongoing monitoring and conservation efforts.

Therefore, it is important to identify the main barriers and facilitators of alpine plant invasions. While there is much research in continental alpine areas, there is limited research in maritime environments, which have distinctive biological, edaphic and geomorphologic features due to the scarcity of snow in winter. Here, we examine the contribution of anthropogenic and biotic factors on non-native plant invasions in the alpine areas of lutruwita (Tasmania), Australia. Specifically, we test whether disturbances associated with roads and livestock grazing facilitate non-native plant invasion and if biotic resistance from native plants and wild grazing animals inhibits such invasion. We used floristic data from: a statewide database; data from long-term grazing exclosures, and data from paired quadrats on roadsides and natural vegetation. Our results showed that non-native plants were associated with roadside disturbance and livestock grazing, with the latter having a legacy effect of 50 years. The persistent effect of stock grazing was evident in the exclusion experiment monitored over 30 years, where non-native plants occurred sporadically in time and space. In contrast, we found that the presence of wild grazing mammals, complete vegetation cover and high native richness, restricted non-native plants, emphasizing the importance of biotic resistance in controlling non-native plant invasions. These results indicate that livestock removal and road closure could be effective in reversing non-native plant invasion in this and other areas with wild vertebrate herbivores and high plant cover.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"8 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mortality was inferred from shifts in population structure, as well as the survival rates (time to death) of 107 radio-tracked lizards. Of 57 deaths whose cause was unambiguous, 32 were due to fatal poisoning by ingesting a cane toad; the other 25 lizards were consumed by pythons. Size and age structure shifted between years, such that the population post-invasion was dominated by smaller, younger lizards, and by females rather than males. Radiotelemetric monitoring confirmed that survival rates were reduced more in males than in females in the post-toad year, with males most at risk late in the dry-season, when food was scarce and females were nesting rather than foraging. Pythons disproportionately consumed larger female lizards during the nesting season.

In this study, we developed a new methodological approach to identify which protected areas should be prioritized for prevention and early detection and which should be prioritized for control of biological invasions. Our methodological approach analyzes the occurrence of invasive species within and around the protected areas and weights the influence of multiple existing pathways to calculate the probability of introduction of invasive species and colonization pressure for each protected area.

Human population density and percentage of pasture cover surrounding the protected area were the most important factors for priority setting in terrestrial protected areas whereas number of aquiculture activities, density of waterways, distance to ports, distance to oil platforms, and distance from sinking points were the most important factors for priority setting in marine protected areas.
