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...

Temporal beta-diversity patterns are highly dependent on fundamental parameters of neutral dynamics

community composition/ demography

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 distance-decay patterns exhibit upper limits and are strongly influenced by four key parameters: the fundamental biodiversity number, local community size, mortality rate, and immigration rate. These findings highlight key differences between temporal and spatial beta diversity, emphasizing the need to account for species pool properties in macroecological studies.

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.

「宗谷バナナ」たわわ　猛暑の中、収穫最盛期　北海道

連日猛暑が続く中、北海道最北端・宗谷岬の名産品「宗谷バナナ」の収穫が最盛期を迎えた。日差しを浴びてたわわに実ったバナナが、一つずつ淡々と収穫されている。　かつては台湾やフィリピンなど南国産が大半を占めていたバナナだが、急激な地球温暖化に伴い、栽培の北限が上昇。東北地方から北海道が最も栽培に適した地域になったことで国産化が進んだ。特に「宗谷バナナ」のブランドで...

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.

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…
