“…Our ability to counter the current loss of biodiversity is dependent on how well we understand the causes of its global, regional and local patterns. However, the trajectory of biodiversity, especially in response to ongoing climate change, is debated (Gonzalez et al , 2016; Suggitt et al , 2019; Harrison, 2020; Le Roux et al , 2020). Changes in species richness due to climate change, nutrient levels and species introductions are often context-dependent (Vellend et al , 2017), and hence hard to predict.…”

SummaryIt is crucial to understand how climate warming and other environmental factors affect biodiversity, especially in the rapidly changing northern latitudes.We use sedimentary ancient DNA (sedaDNA) metabarcoding to estimate taxonomic richness, and local and regional species pools of terrestrial plants for 10 lakes in northern Fennoscandia over the Holocene.In total, 288 taxa were found in the 316 samples analysed, with local species pools of 89-200 and mean taxonomic richness of 21-65 per catchment. Quality control showed that sedaDNA is a reliable estimate of richness. Local and regional species pools showed a steep increase in the Early Holocene, when the highest rate of warming took place, and continued to increase through the Middle and into the Late Holocene, although temperature decreased over these periods. Only the regional species pool levels off during the last two millennia. Richness and local species pools were always higher in catchments with higher bedrock nutrient availability.We find sedaDNA to be a good proxy for diversity, opening avenues to detect patterns hereto unknown, and we provide a robust methodological approach to its application. Our findings suggest we can expect time lags and environmental factors to affect species richness also of the following global warming.

Biological invasions are a major threat to Australia. Information on alien flora in Australia is collated independently by different jurisdictions, which has led to inconsistencies at the national level, hampering efficient management. To harmonise different information sources, we present the Alien Flora of Australia (AFA), a nationally unified dataset. To create the AFA, we developed an R script that compares existing data sources (the Australian Plant Census and state and territory censuses), identifies mismatches among them and integrates the information into unified invasion statuses at the national scale. The AFA follows the taxonomy and nomenclature adopted for the Australian Plant Census, introduction status and impact of plants known to occur in Australia. The up-to-date information presented in this dataset can aid early warning of alien species invasions, facilitate decision-making at different levels, and biosecurity at national scale. The associated script is ready to be implemented into new versions of the AFA with updated releases of any of the data sources, streamlining future efforts to track of alien flora across Australia.

“…Biological invasions have increasingly gained attention over the past decades within the scientific community (Nuñez et al 2022), that recognises the importance of having high quality, easy-toaccess, standardised and unified data sources (Latombe et al 2017). Having standardised datasets at large spatial scales allows tracking and monitoring the status of biological invasions, making future predictions and prioritizing invasion-based management actions (Hulme et al 2009;Le Roux et al 2020). Despite the increase in the number of publications on biological invasions over the last three decades, within the same period ongoing debates have also taken place.…”

Towards integrating and standardising information on plant invasions across Australia

Over the last decades, terminology to refer to invasion status along the introduction-naturalisation-invasion continuum have been based either on overcome barriers or on impact-based frameworks, generating debates within the scientific community. The lack of agreement with regards to definitions have sometimes hampered combining information from sources based on different criteria. In Australia, information on plant invasions is contributed independently from different jurisdictions, which has led to inconsistencies regarding both, terminology to refer to invasion ecology, and invasion status at the national level, therefore impeding efficient management. In this paper, we review and discuss the steps taken to harmonise the different terminologies used across Australian states, we identify the mismatches in introduction at the jurisdictional and national scales and proposed detailed prioritisation systems to tackle mismatches at both scales and to integrate information into a standardised system at the national scale. This integration exercise has made possible the creation of a standardised dataset at the Australian national scale (the Alien Flora of Australia). In Australia, having an integrated system for referring to and tracking alien flora can, not only aid early warning and prevention of introduced species, but also facilitate decision-making at the jurisdictional levels, and biosecurity measures at the national scale. We also highlight the opportunities arising from integrating contrasting information into the continental scale.
