🌿 How belief can protect nature

A new model suggests that fear of supernatural punishment for harming nature can evolve to curb overuse of resources, helping societies live sustainably.

持続可能性のためのツールとして機能する古代神の罰👺

「民が超自然的な罰を信じる度合い」「自然資源に対する搾取強度」「環境資源の有用度」を組み合わせた数理モデルを開発!
超自然的な罰を畏れる民なら、過剰搾取が阻まれて資源が回復しやすくなるのだ

「超自然的な罰に対する恐怖は、環境への害を軽減し、人間社会と自然との持続可能な関係を促進する可能性がある」

日本の民話に登場する👺天狗👺は、聖地を汚す傲慢な者や、神聖な空間(山や深い森)を乱すふとどき者を罰する自然の守護者💪

▶自然を破壊する人を罰する神や精霊への信仰は、世界中に存在する
▶そのような信仰によって、環境破壊が食い止められる条件を数学的に導いた
▶宗教的伝統も環境保全に貢献する可能性が考えられる

Beetles have taken me a long way!
Huge congratulations to Andrés Baselga, who has just been promoted to Full Professor of Zoology at Univ. Santiago de Compostela @usc.gal

Yesterday we enjoyed his talk - from collecting beetles as a teen to developing methods for studying biodiversity.

This looks to be a fundamental theoretical advance by @jpodwyer.bsky.social et al. Using linkage disequlibrium-based Ne to back out σ² and then predict fluctuation sizes from a single temporal snapshot is a real advance for broad application 🧪🌐https://www.science.org/doi/10.1126/science.adu6396
Genomic demography predicts community dynamics in a temperate montane forest
Species population sizes fluctuate over time, and these temporal dynamics play a key role in governing the maintenance of biodiversity. Although modeling approaches have been developed to characterize...

Want to do vegetation ecology in Taiwan? I am still searching for postdocs, so if interested, check the ad below and apply!

We focus on ecological drivers of cloud & monsoon forests in mountains and how to explain them using plant functional traits.

🌍 New theoretical paper out!
How do key parameters of neutral theory control temporal beta diversity?
Simple simulations reveal:
✅ Temporal distance-decay has upper limits
✅ Strong parameter dependency

Time ≠ Space — obvious, but still overlooked.
Temporal beta‐diversity patterns are highly dependent on fundamental parameters of neutral dynamics
Temporal beta diversity describes changes in community composition over time, yet its fundamental properties under neutral dynamics remain unclear. Using simulations, we demonstrate that temporal dis...

New paper out! 🌿🦋
How does tropical forest restoration affect butterfly communities?
We analysed over 10,000 fruit-feeding butterflies in Uganda and found that as forests mature, body size diversity increases, distributions become more balanced, and intraspecific variation matters.
Individual-level size distribution patterns in fruit-feeding butterfly communities along a forest restoration gradient in the Afrotropics
The loss and degradation of tropical rainforests pose significant challenges to global conservation, yet the impact of forest restoration on the funct…
