In a leap towards managing the ecological challenge posed by alien plant species, a recent study outlines a methodology for integrating and harmonising data on plant invasions across Australia.
Published in NeoBiota, the researchers created a standardised and unified database at the Australian national level, known as the Alien Flora of Australia, which will help monitoring and early-warning of alien flora, prevent species introduction, streamline decision-making, and bolster biosecurity efforts.

Focusing on Australia, a federally managed country, they identified mismatches in definitions and records of invasion status for vascular plant taxa across different jurisdictions. They then proposed prioritisation procedures to tackle those mismatches and to integrate information from ten data sources into a harmonised workflow at the national scale.
“The importance of harmonising terminology on biological invasions cannot be overstated. It is not merely an academic pursuit but a practical necessity, essential for realising meaningful advancements in invasion ecology.”
Dr Irene Martín-Forés
The authors recognise that the words used to describe alien species profoundly influence how humans perceive, study, and manage biological invasions. In federally managed countries, the problem is worse, as fragmented terminologies across different jurisdictions create confusion and inconsistencies in species classification and invasion statuses, therefore hindering effective communication among researchers, policymakers, and stakeholders.

The benefits of harmonising terminology on invasion ecology and combining contrasting data sources into a unified dataset at the Australian national scale extend far beyond semantic clarity. It enhances the accuracy of available datasets, and subsequently the reliability of scientific research focused on plant invasion. It also streamlines communication across jurisdictional borders and disciplines and empowers evidence-based decision-making in biosecurity management.
The workflow developed and its associated R script can be easily adapted to be used in any federally managed country, saving future efforts into trying to deal with inconsistencies in species’ invasion statuses.

The city of Cambridge and the Wellcome Campus hosted the Final General Assembly of the EU-funded project BiCIKL (acronym for Biodiversity Community Integrated Knowledge Library): a 36-month endeavour that saw 14 member institutions and 15 research infrastructures representing diverse actors from the biodiversity data realm come together to improve bi-directional links between different platforms, standards, formats and scientific fields. Consortium members who could not attend the meeting in Cambridge joined the meeting remotely.
After a welcome cocktail reception on Monday evening at Hilton Cambridge City Centre, on Tuesday, the consortium made an early start with a recap of BiCIKL’s key milestones and outputs from the last three years. All Work Package leaders had their own timeslot to discuss the results of their collaborations.
They all agreed that the Biodiversity Knowledge Hub – the one-stop portal for understanding the complex – yet increasingly interconnected landscape of biodiversity research infrastructures – is likely the flagship outcome of BiCIKL.
Prof. Lyubomir Penev, project coordinator of BiCIKL and founder/CEO of Pensoft Publishers at the BiCIKL’s third and final General Assembly in Cambridge, United Kingdom.
In the afternoon, the participants focused on the services developed under BiCIKL. Amongst the many services resulting from the project some were not originally planned. Rather those were the ‘natural’ products of the dialogue and collaboration that flourished within the consortium throughout the project. “A symptom of passion,” said Prof. Lyubomir Penev, project coordinator of BiCIKL and founder/CEO of Pensoft Publishers.
An excellent example of one such service is what the partners call the “Biodiversity PMC”, which brings together biodiversity literature from thousands of scholarly journals and over 500,000 taxonomic treatments, in addition to the biomedical content available from NIH’s PubMed Central, into the SIB Literature Services (SIBiLS) database. What’s more, users at SIBiLS – be it human or AI – can now use advanced text- and data-mining tools, including AI-powered factoid question-answering capacities, to query all this full-text indexed content and seek out, for example, species traits and biotic interactions. Read more about the “Biodiversity PMC” in its recent official announcement.
Far from being the only one, the “Biodiversity PMC” is in good company: from the blockchain-based technology of LifeBlock to the curation of the DNA sequences by PlutoF, the BiCIKL project consortium takes pride in having developed twelve services dedicated to FAIR and linked ready-to-use biodiversity data.
On Wednesday, the consortium focused on BiCIKL’s activities from the Transnational and Virtual Access Pillar, which included both presentations by each open call leader and VA leader, as well as open discussions and a recap of what the teams have learnt from these experiences.
A panel discussion took place on Thursday as part of an open event, where BiCIKL partners and ELIXIR Biodiversity and Plant Communities came together to discuss the Future of Biodiversity and Genomics data integration at the EMBL Wellcome Genome Campus.
Thursday was dedicated to an open event where BiCIKL partners and ELIXIR Biodiversity and Plant Communities came together to discuss the Future of Biodiversity and Genomics data integration at the EMBL Wellcome Genome Campus. You can find the agenda on BiCIKL’s website.
After 36 months of action, the BiCIKL project will officially end in April 2024, but does it mean that all will be done and dusted come May 2024? Certainly not, point out the partners.
To ensure that the Biodiversity Knowledge Hub will not only continue to exist but will not cease to grow in both use and participation, the one-stop portal will remain under the maintenance of LifeWatch ERIC.
In conclusion, we could say that an appropriate payoff for the project is “Stick together!” as put by BiCIKL’s Joint Research Activity Leader Dr. Quentin Groom.
Final words at the third and last General Assembly of the BiCIKL project.

The critical role of gardeners in identifying ‘future invaders’ – ornamental plants that could become invasive species – has been revealed by researchers from the University of Reading and the Royal Horticultural Society.
Looking to draw from the experience of Britain’s millions of gardeners, the team created an online survey where gardeners reported ornamentals that showed ‘invasive behaviour’ in their gardens.
Based on reports from 558 gardeners, 251 different plants were identified as potential invaders, reflecting the extensive variety and potential risks in domestic gardens. The team analysed the results, considering both domestic and global invasive status, and prioritised ornamental plants of concern. The result was a shortlist of plants which need their invasive potential in Britain and Ireland assessed.
The shortlisted plants include, for example: Mexican fleabane(Erigeron karvinskianus);cypress spurge (Euphorbia cyparissias);chameleon plant(Houttuynia cordata);Himalayan honeysuckle(Leycesteria formosa);and purple top(Verbena bonariensis).

The results, published in the open-access journal NeoBiota, highlight the role of gardeners in the early detection of invasive species, a key factor in the global nature crisis. Such proactive identification could prove invaluable for future risk assessments and prevention strategies.
“The simple yet structured scheme we developed was used to prioritise which of the around 70,000 ornamental plants available to buy in the UK could be future invaders. This is crucial for focusing research efforts and resources, such as conducting formal risk assessments to explore the invasive potential of those shortlisted.”
Tomos Jones, lead author
John David, RHS Head of Horticultural Taxonomy, said: “It’s important to remember that these shortlisted plants are not yet officially invasive, and that many non-native plants that occur in the wild present no threat to our native biodiversity.”

A team of experts has created the first database of field studies on the impacts of invasive plants on native species, communities and ecosystems in Europe.
The dataset comprises 266 peer-reviewed publications reporting 4,259 field studies on 104 invasive species across 29 European countries. It is the first harmonised database of its kind at continental scale, and is freely accessible to the scientific community for future studies. Notably, one third of the studies focused on just five species that invade several central European countries.

The comprehensive database indicates that invasive plants impact other plants, animals and microbes, all trophic levels (herbivores, parasites, plants, pollinators, predators, omnivores, decomposers and symbionts) and numerous ecosystem processes.

More than half of the studies were conducted in temperate and boreal forests and woodlands and temperate grasslands. Major knowledge gaps are found in Baltic and Balkan countries, in desert and semi-arid shrublands, subtropical forests and high mountains.
Prof. Montserrat Vilà, coordinator of this task, highlights that the database provides information on whether the invasive species increase, decrease or have a neutral effect on the ecological variable of study. This allows investigation into the circumstances in which the invader has contrasting effects.

The database will be updated as new field studies on the ecological impacts of invasive species are published. “We hope for more studies on species that are still locally rare and with restricted distribution,” Prof. Montserrat Vilà says, “this database is of interest for academic, management and policy-related purposes.”

Insects are among the most prolific and successful invaders of new habitats, but not all regions are equal in the numbers of insects that have spread beyond their borders.
Flows of non-native insects between N. America, Europe, and Australasia. Numbers are the total count of species established from donor to recipient.
European insects, in particular, stand out as highly successful invaders into other world regions. Why? Biologists have long understood that species are spread through international trade: insects are frequent stowaways in trade goods, and the value of international trade between world regions can be a good predictor of how many non-native species are exchanged.
However, recent research led by Dr. Rylee Isitt of the University of New Brunswick, and published in the journal NeoBiota, shows that after accounting for patterns of international trade, the number of insects that have spread from Europe into North America, Australia, and New Zealand far exceeds expectations.
Since patterns in international trade can’t explain these insect invasions, the researchers looked for other potential explanations. It’s possible that European insects are simply more numerous or better invaders than their North American or Australasian counterparts. However, Dr. Isitt and his collaborators didn’t find evidence for that – at most, there are only slightly more European species with the capacity to invade compared to North American and Australasian species.
Another possibility is North American and Australasian habitats are easier to invade than European ones. But prior research has shown that Europe has been heavily invaded by Asian insects, suggesting that it is no more resistant to invasion than North America or Australasia.
Instead, Dr. Isitt and collaborators have proposed that the abundance of European insect invaders may be a result of deliberate introductions of non-native plants into Europe’s colonies. Plants introduced into European colonies could have promoted the spread of European insects into North America and Australia by two different means.
First, insects may have been introduced along with the plants. Second, introduced plants may have provided suitable food and habitat for subsequent arrivals of non-native insects, who might have otherwise found the native flora to be unpalatable or unsuitable as a habitat.
Cumulative discoveries (observed and modelled) and establishments (modelled) of non-native insects exchanged between Europe (EU), North America (NA), and Australasia (AU) versus cumulative import value (inflation-corrected to 2020 British pounds sterling, billions), 1827–2014. Alternating background shading indicates decadal increments, with shading omitted prior to the 1940s for clarity.
Although the researchers haven’t completely resolved the mystery of the overabundance of European insects, they have ruled out several possibilities, leaving the connection to introduced plants as the prime suspect. The next steps? Determining to what extent European insects spread through introduced plants compared to insects from other world regions.
Because invasive species are reshaping our world, we need to understand how they move and establish. Evidence is mounting that trade in plants and plant products is responsible for a large proportion of insect invasions. If the researchers’ hypothesis is correct, the spread of European insects may be a remarkable example of the unintended consequences of deliberate plant introductions.

Despite the success of 2023, the Pensoft team is keener than ever to improve in every aspect in the coming year. A massive thank you to every author, editor, reviewer and reader of Pensoft’s journals, and a very happy New Year!
October and November 2023 were active months for the Pensoft team, who represented the publisher’s journals and projects at conferences in Europe, North America, South America, Oceania and Asia.
Let’s take a look back at all the events of the past two months.
The Biodiversity Information Standards Conference 2023
The annual gathering is a crucial platform for sharing insights, innovations, and knowledge related to biodiversity data standards and practices. Key figures from Pensoft took part in the event, presenting new ways to improve the management, accessibility, and usability of biodiversity data.
Prof. Lyubomir Penev, founder and Chief Executive Officer of Pensoft, gave two talks that highlighted the importance of data publishing. His presentation on “The Biodiversity Knowledge Hub (BKH): A Crosspoint and Knowledge Broker for FAIR and Linked Biodiversity Data” underscored the significance of FAIR (Findable, Accessible, Interoperable, and Reusable) data standards. BKH is the major output from the Horizon 2020 project BiCIKL (Biodiversity Community Integrated Knowledge Library) dedicated to linked and FAIR data in biodiversity, and coordinated by Pensoft.

Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms.
Often introduced unintentionally by human activities, invasive alien species can outcompete and overwhelm native flora and fauna, driving species to the brink of extinction and disrupting the balance of ecosystems. Understanding why exactly they establish in new locations and how they got there in the first place is crucial if we are to mitigate their destructive effects. Unfortunately, there isn’t enough research on this, and the answers might not always be straightforward.
A research team from AgResearch and Better Border Biosecurity (B3) investigated the biological risk posed by soil on the external surfaces of sea freight such as shipping containers or used machinery at sea ports in New Zealand. With their work, the researchers hope to facilitate the assessment of relative biosecurity risks between different introduction pathways and contribute to the development of more efficient measures against them.
The team found soil on most types of sea freight, irrespective of origin, with all soil likely to vector microbes, including plant pathogens. The amount of soil recovered from a single sea container was 5.3 kg, while the overall mean weight collected from sea freight was 417g, with most of the soil found on the underside of sea freight.
“While the presence of soil is perhaps not surprising, the presence of live bacteria, fungi, worms, seeds and insects associated with the soil was of greater concern. Various regulated biosecurity organisms were recovered from the samples, including plant-parasitic worms, seeds, insects and spiders that were not recorded as being present in New Zealand,” says Mark McNeill of AgResearch, who led the study.

“Not only does the spread of exotic species through these networks represent significant environmental, economic and social costs to natural and agricultural environments if invasive alien species were to establish, a loss of biodiversity is also an expected consequence of invasive alien species establishment. For islands, the implications can be significant, as they have high levels of endemism and invasive alien species establishment can lead to extinction of species as well as biodiversity declines,” the researchers write in their paper, which was published in the open-access journal NeoBiota.
Compared to a previous study on contaminated footwear carried in luggage by international airline passengers, the number and diversity in soil on sea freight was smaller than soil transported in more protected environments (e.g., footwear in luggage). This showed that biosecurity risk can vary with pathway. However, prioritising one soil pathway over another according to the risks they present, and differentially allocating resources is problematic, because the relative risk is dynamic, dictated by factors such as new pests or diseases entering the respective pathways.
Even so, the researchers suggest that contaminated sea freight is an important introduction pathway for exotic species. The establishment of such species can be prevented by cleaning containers prior to departure, inspection at the border, and further cleaning where required.
