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 🌍

🔧 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

💥 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.

🎯 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

✅ 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

🧩 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.

🚨 New SDM-methods paper fresh out of the science oven! 🍞📊
We developed super simple data thinning methods to tackle an oversimplified and superficially addressed issue in SDMs --- environmental sampling bias!

Correcting environmental sampling bias improves transferability of species distribution models

Sampling bias is an inherent problem in widely available biodiversity data, undermining the robustness of correlative species distribution models (SDMs). To some extent, subsampling occurrence data c....

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).
