Abstract Critics of invasion biology have argued that conservation science is biased against introduced species. We reviewed 300 randomly selected articles described the ecological effects species and assessed whether they were framed negatively, neutrally, or positively. then asked their framing was related to harms as defined by community; knowledge about species, using species’ taxonomy, habitat, region proxies; journal’s focus prestige author's country affiliation. also analyzed differed across space time. If unbiased, one would expect negative be more common for associated with harm. found negatively in two thirds articles. Introduced regardless attributed taxonomies, journals, globe, Our results support are persistently regarded harmful, a bias raises questions validity claims made them.

Abstract Aim Reducing the rate of alien species introductions is a major conservation aim. However, accurately quantifying at which are introduced into new regions remains challenge due to confounding effect observation efforts on discovery records. Despite recognition this issue, most analyses still based raw records, leading biased inferences. In study, we evaluate different models for estimating introduction rates, including that use auxiliary data effort, and identify their strengths weaknesses. Innovation We compare four models: (1) naïve model assumes perfect detection; (2) proposed by Solow Costello (the S&C ); (3) constant detection : modified version with probabilities (4) novel sampling proxy uses external effort. simulate records varying lengths, rates temporal patterns explore scenarios under these estimate underlying rates. (5) also include code perform Belmaker using independent number native species. Main conclusion found length annual recorded play crucial role in performance all models. Under simulated high detection, usually best‐performing model, but it falls short when low. Moreover, find simulations likely mimic real‐world cases (i.e. non‐monotonic probability detection), incorporating effort substantially improve estimates. This highlights importance considering To facilitate models, provide decision workflow dedicated R package (‘alien’).

Monitoring the extent to which invasive alien species (IAS) negatively impact environment is crucial for understanding and mitigating biological invasions. Indeed, such information vital achieving Target 6 of Kunming–Montreal Global Biodiversity Framework. However, to-date indicators tracking environmental impacts IAS have been either lacking or insufficient. Capitalizing on advances in data availability assessment protocols, we developed track realized potential IAS. We also an status indicator assess adequacy underlying indicators. used 75 naturalized amphibians from 82 countries demonstrate at a global scale.

Abstract Aim The Hemiptera is the fifth‐largest insect order but among non‐native species approximately tied with Coleoptera as most species‐rich (Hemiptera comprise 20% more than in world fauna). This over‐representation may result from high propagule pressure or invasiveness. Here, we assess reasons for this group by analysing geographical, temporal and taxonomic variation numbers of historical invasions. Location Global. Method We assembled lists invasions 12 regions, countries islands (Australia, Chile, Europe, New Zealand, North America, South Africa, Korea, Japan Galapagos, Hawaiian, Okinawa Ogasawara Islands) border interception data nine Canada, European Union, United Kingdom, Hawaii, Japan, USA mainland Africa). Using these data, identified hemipteran superfamilies that are historically over‐represented established species, arrivals (proxied interceptions). also compared patterns establishments suborders regions. Results Across all over‐ under‐representation were similar. Aphidoidea, Coccoidea, Aleyrodoidea, Cimicoidea Phylloxeroida species. These same not consistently intercepted indicating does completely explain tendency some to be Asexual reproduction common trait key explaining invasion success superfamilies. Conclusions conclude both invasiveness drivers Sternorrhyncha suborder (aphids, scales, whiteflies) plays a major role exceptional general. rates provide justification biosecurity measure focusing on exclusion group.
