occumb: An R package for site occupancy modeling of eDNA metabarcoding data

Keiichi Fukaya*, Yuta Hasebe
doi.org/10.1002/1438...

*recipient of 13th Population Ecology Young Scientist Award🏆

amplicon sequencing/ Bayesian inference/ hierarchical modeling
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using the package. An example application targeting aquatic insects highlights the effectiveness of using biological replicates to minimize false-negative results in species detection.

Combining transient dynamics and logistic-asymptotic growth to study the recovery of two seabird populations after rat eradication

Merlène Saunier et al
doi.org/10.1002/1438...

density-dependent/ population dynamics/ recovery/ tropical seabirds/ #ornithology
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century. The analysis of transient dynamics, which occur after environmental disturbances, helped to better understand the discrepancies between observed field growth and theoretical estimates based on population models, revealing disruptions in age structure likely due to past rat predation.

今号のEditor’s Choiceは、有効集団サイズの推定に関する特集論文です
EiC🗨️この研究では、非常に大きな個体群における有効集団サイズの推定に関して、十分なサンプル数があれば、Sibship Frequency（SF）法とLinkage Disequilibrium（LD）法の両方が正確な推定を提供できることが示されました。特に、SF法は個体群のサイズ変動や遺伝子型の誤りに対しても頑健であり、精度が高いことを明らかにしています
