InvaPact III workshop is now over: WHAT A WEEK! ~60 experts from 30 countries putting their brainpower together for an unique collaborative project.
Work hard, play hard: they really followed my motto!
Powerful publications on the way!

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far-reaching consequences for society and the economy. Preventing the introduction and spread of ....

Today was my first day as a Research Associate 🤓 at @fletcherecology.bsky.social group in the @camzoology.bsky.social University of Cambridge!!! Looking forward to mapping global connectivity 👣🏞🌍 and its applications for biodiversity conservation and restoration 🦏🌿!!!

🚀 What’s next?
We’re applying this method to 600+ alien amphibians and reptiles 🦎🐸 to map their global invasion potential & understand global biotic homogenization 🌍

Arman Pili @armanpili.bsky.social · Jul 10

🔧 Our fix:
We sub-sample both presences & backgrounds across the full environmental gradient available to a species.
This helps SDMs better:
📌 Explain niches
📍 Predict current distributions
🕰️ Project future/range-shifting scenarios

Arman Pili @armanpili.bsky.social · Jul 10

💥 What went wrong?
Environmental sampling bias!
The model didn’t capture the true species-environment relationship—it just overfit to the oversampled Australian conditions.
➡️ The data were unbalanced in environmental space, and it showed.

Arman Pili @armanpili.bsky.social · Jul 10

🎯 The scenario:
Goal: Predict the global invaded range of the cane toad 🐸
Data:
🇧🇷 1000 records from native Brazil
🇦🇺 2000 from invaded Australia
🇵🇭 100 from invaded Philippines

👉 All thinned using standard methods (SOA)

Result: SDMs accurately predicted AU and BR(overfit), but mehhh in PH

Scientific Reports - Niche shifts and environmental non-equilibrium undermine the usefulness of ecological niche models for invasion risk assessments

Arman Pili @armanpili.bsky.social · Jul 10

✅ The Solution:
Apply 'Habitat Stratified Sampling Design' when thinning both data.

Our new methods:
1️⃣ Environmental clustering
2️⃣ Environmental distance thinning

Both outperform conventional approaches for:
🌍 Explaining
📍 Predicting
⏳ Projecting species distributions

(3/8)

Arman Pili @armanpili.bsky.social · Jul 10

🧩 The Problem:
Environmental sampling bias = when some environmental conditions are oversampled just because they’re common or widespread across the landscape.
➡️ This skews the models and messes with predictive accuracy.

We're looking for the input of IAS data collectors, users or curators to take part in a survey to help shape the future of IAS data standards and accessibility.

This survey is hosted by the GBIF and @tdwg.org task groups on IAS ⭐

The loss of megafauna over the last 50,000 years has caused ecological theories to be based on already-degraded ecosystems.

It finally happened: my future #student #mentee asked me about my paper that I led and #published years ago (my first first-author paper), only to apologise that I forgot what I did in that #paper, nor do I have a copy of it in my computerS (it is under paywall).

🙀 How severe are #bioinvasions in protected areas? 🌱🌍
In our latest study, we used EICAT to uncover the severity and mechanisms of these impacts. Tools like EICAT are essential for understanding these challenges and driving effective conservation efforts. #InvasiveSpecies

Aquaculture is an important activity sector for many countries. Unfortunately, it can also be the source of #bioinvasions. Focusing on crustaceans, our last paper presents a very simple framework to limit these invasions:
