It’s official! After years of hard work by IPBES experts, the #BizBiodiversity Assessment Report is approved by the Plenary at #IPBES12!

Congratulations to all on this achievement for people and #nature!

Thank you to all who contributed to this successful outcome.

41 #IPBESfellows will be in Manchester from 2-4 February to attend a workshop where they will learn about science-policy interactions and have the opportunity to engage with IPBES experts & policymakers present at #IPBES12.

Oh yesss it was good carnage! And joining the ceilidh was my best decision that night, and a contender for the highlight of my first BES!!! It was fun dancing with you and everyone!

I have learnt a lot as an Assoc Editor in-training at the @jappliedecology.bsky.social, and I feel privelaged to have THE @martin-nunez.bsky.social as my mentor! It was so great to finally meet you in person, and learn from you more!!!

🎉 Congratulations to Dr Charles Emogor winner of the @zslscience.bsky.social Thomas Henry Huxley Award and Marsh Prize 2025 for the best PhD thesis submitted by a UK university.

Spatial Ecology and Conservation Modeling This textbook provides a foundation for modern applied ecology. It follows a rapidly changing field with updates of concepts, methods, and code.

Really happy to share that the Second Edition of our book, "Spatial Ecology and Conservation Modeling", is now out and available online!

We provide a foundation for applied spatial ecology with a focus on learning-by-doing.

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 ....

🚀 What’s next?
We’re applying this method to 600+ alien amphibians and reptiles 🦎🐸 to map their global invasion potential & understand global biotic homogenization 🌍
(8/8)

🔧 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
(7/8)

💥 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.
(6/8)

🎯 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

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

🤺 I’ve had beef with this issue since my MSc days. It all started here:

✅ 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)

🧩 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.

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....
