IPBES Invasive Alien Species Assessment, database for Chapter 4. Impact Evidence Database

This is a database described in the data management report for chapter 4 of IPBES thematic assessment on invasive alien species and their control. Data were gathered on direct observations of impacts from published literature, including grey literature, in order to form a database on the evidence to which invasive alien species impact, negatively and positively, nature, nature's contributions to people and good quality of life for Chapter 4 of IPBES thematic assessment of invasive alien species and their control. The criteria for inclusion were a published direct evidence of an impact on native species, a change in ecosystem properties, nature's contributions to people and the extent to which humans were affected through changes in their constituents of well-being.   Updates to version 3: 1) Assessor “EAM” has been replaced by “Ester Mostert”, 2) There were 50 Unique IDs that were paired. These are now differentiated by adding an a and b to the end of these to make them truly unique, 3) Removed 40 duplicates 4) RowID were re-numbered to reflect the unique number of rows

Trait-habitat associations explain novel bird assemblages mixing native and alien species across New-Zealand landscapes

Aim: Species introductions have reshaped island faunas for the last 200 years, often threatening native biodiversity. Approximately equal numbers of native and alien species currently co-occur in the New Zealand avifauna, but they show distinct habitat use. Antagonistic interactions, habitat affinities and legacies of introduction history may concur to explain their segregation along habitat gradients. To investigate these processes, we explored how habitat, ecological traits and introduction history relate with the current composition of bird assemblages. Location: New Zealand Taxon: Birds Methods: We analysed 917 bird point counts spread along habitat and elevation gradients in the Canterbury region, South Island, and related 10 ecological traits to landscape composition using a three-table ordination method known as 'RLQ analysis', accounting for spatial autocorrelation and phylogeny. We tested whether alien species' positions in the RLQ were related to proxies of introduction history. Results: Eighteen endemic, 11 native and 19 alien species were distributed along a gradient from forest to open-habitat assemblages, in relation to foraging mode, nesting site and body size. A second gradient segregated species between native and exotic forests according to territoriality, sedentarity and diet. Traits accounted for the separation of native and alien bird species in forests, but not in open habitats. Phylogenetic signals emerged from the separation of native and alien species by forest type, and spatial structures suggested a landscape-level, rather than regional or local determinism. These correlations were independent of introduction history, although open-habitat assemblages tended to host alien species introduced later in time. Main conclusions: Habitat type and resource availability explain the spatial partitioning of New Zealand bird assemblages between native and alien species more consistently than competitive exclusion. We conclude that trait-mediated ecological differences among species have likely played a predominant role in species' segregation among landscapes, while maintaining endemic bird assemblages in native forests.

Dataset for: Designing a surveillance program for early detection of alien plants and insects in Norway

Naturalized species of alien plants and animals comprise < 3% of biodiversity recorded in Norway but have had major impacts on natural ecosystems through displacement of native species. Encroachment of alien species has been especially problematic for coastal sites close to transport facilities and urban areas with high-density housing. The goal of our field project was to design and test a surveillance program for early detection of alien species of vascular plants and terrestrial insects at the first phase of establishment in natural areas. In our 3-year project (2018–2020), we sampled 60 study plots in three counties in the Oslofjord region of southern Norway. Study plots (6.25 ha) were selected by two criteria: manual selection based on expert opinion (27 plots) or by random selection based on weights from a hotspot analysis of occurrence of alien species (33 plots). Vascular plants were surveyed by two experienced botanists who found a total of 239 alien species of vascular plants in 95 rounds of surveys. Insects and other invertebrates were captured with a single Malaise trap per site, with 3-4 rounds of repeated sampling. We used DNA-metabarcoding to identify invertebrates based on DNA extractions from crushed insects or from the preservative media. Over 3,500 invertebrate taxa were detected in 255 rounds of sampling. We recorded 20 alien species of known risk and 115 species that were new to Norway, including several 'doorknocker' species identified by previous risk assessments. We modeled the probabilities of occupancy (y) and detection (p) with occupancy models with repeated visits by multiple observers (vascular plants) or multiple rounds of sampling (insects). The two probabilities covaried with risk category for alien organisms and both were low for species categorized as no known or low risk (range = 0.052 to 0.326) but were higher for species categorized as severe risk (range = 0.318 to 0.651). Selecting sites at random or manually did not improve the probability of finding novel alien species, but occupancy had a weak positive relationship with housing density for some categories of alien plants and insects. We used our empirical estimates to test alternative sampling designs that would minimize the combined variance of occupancy and detection (A-optimality criterion). Sampling designs with 8–10 visits per site were best for surveillance of new alien species if the probabilities of occupancy and detection were both low, and provided low conditional probabilities of site occupancy (psi-hat(cond) £ 0.032) and a high probabilities of cumulative detection (p-hat(star) ³ 0.943). Our field results demonstrate that early detection is feasible as a key component of a national surveillance program based on early detection and rapid response (EDRR).

Data from: How science communications can help build societal perceptions of invasive alien species and their impacts on the environment

In this study, we investigated the reported beneficial aspects of the invasive alien plant species (IAPS) and argued that, over time and space, the detrimental impacts of the IAS might endanger sustainable livelihoods. The data set contains the following files: Data_S1.xlsx: The file contains details of 154 literature reports. From each paper, we extracted IAPS names (both as reported and standardized), taxonomic information (family and taxon rank), year, country, the scale of observation, and reported beneficial impacts. The beneficial impacts were further categorized into 13 use categories at TDWG (Taxonomic Databases Working Group) Level-1 states (in binary format - 1 indicates the IAPS use and 0 indicates not in use for the individual category). The Metadata_S1.pdf file contains detailed information on preparing literature records for data extraction, the data extraction process, and data organization.
