Very different. We had companies from the food sector, paper production and a bank.

Buhuuuu 😭 Our proposal was rejected by biodiversa+ for the transformative change call ☹️☹️☹️

I know that this is not uncommon in science but it always sucks. We put quite some effort into this and it is such a nice one. Maybe next time.

How reliable are model-based blacklists of invasive plant species if occurrence & environmental data are limited & under different model choices? New paper by PhD researcher Valén Holle @jappliedecology.bsky.social #SDM #invasive #plants #Pacific besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Uncertainty in blacklisting potential Pacific plant invaders using species distribution models

SDMs can provide valuable support for planning the preventive management of alien species. However, our findings show that blacklist outcomes are highly sensitive to modelling decisions. While ensemb....

This week I had the pleasure of presenting our work on #biodiversity #impacts of companies at a workshop by Fauna & Flora, #IUCN and Taskforce on Nature-related Financial Disclosures #TNFD.

A fantastic opportunity to exchange across sectors.

Many thanks for having me! I enjoyed it very much. 🙏

This was a massive effort led by the core team consisting of Laura Meyerson, Petr Pysek, Dave Richardson and myself. Their support was incredible, and I am grateful to work with such experienced and dedicated researchers.

The whole author team was fun to work with.

The study is based on the IPBES invasive alien species assessment, chapter 2 (doi.org/10.5281/zeno...), but fully revised, restructured and updated. We put a lot of effort into coverage of microorganisms, fungi and other under-represented groups. Still, huge gaps hamper a full coverage.

Data gaps of the distribution of non-native species are huge and widespread. But quantifying gaps and their influence on results is very challenging.

The comprehensiveness of our assessment allows to provide a good overview of knowledge and lack of knowledge.

Hanno Seebens @hannoseebens.bsky.social · Aug 14

Main findings:

Non-native species are everywhere, even in remote places (islands, deep sea, Antarctica, high mountains).

Trends are increasing and will increase in the future.

Data gaps are huge. No inventory is complete. Particularly for invertebrates, aquatic species and invertebrates.

Very excited to share this review. Stemming from the @ipbes.net IAS Assessment, it is the most comprehensive and up-to-date synthesis of the status of invasive alien species globally. An essential reference for anyone interested in #bioinvasions 🌎🌐 🧪 onlinelibrary.wiley.com/doi/10.1111/...

What an honour! 😊 🤩

I realised that the famous data platform "Our World in Data" has now our data set of first records of alien species on their platform.

I use this platform quite a lot and I am very happy (and proud) to find our data set there as well 🤩

Very interesting meeting of the #CBD inter-liaison group of #invasive alien #species!

A small group but with representatives from very different organisations from sectors of eg trade, tourism, agriculture, biodiversity. Amazing to see how much is going on. But this needs to be coordinated!

On my way to the meeting of the #CBD inter-liaison group on #invasive alien #species in Paris.

Looking forward discussing gaps and needs to meet the global biodiversity taget on #IAS

Second day our our @b-cubed.eu annual meeting. Discussing

- use of @gbif.org data cubes for modelling and indicators
- indicators of biodiversity change (incl. #bioinvasion indicators)
- stakeholder engagement
- uncertainty and robustness of results

Fascinating and challenging 🤓

Hanno Seebens @hannoseebens.bsky.social · Mar 26

First day of our @b-cubed.eu project meeting is over.

Quite a lot of new software products developed based on species occurrence cubes by @gbif.org. The cubes are used eg for SDMs, invasibility cubes and to calculate a set of indicators of biodiversity change.

Soon all online and as #R packages.
