Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Lucas Henrique Sousa da Silva et al
doi.org/10.1002/1438...

caatinga/ dry forests/ Gastropoda/ invasive species/ seasonality
Graphical abstract: We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year, reflecting contrasting ecological strategies. These patterns are especially relevant for understanding how native and invasive species respond to climate seasonality in human-altered freshwater environments.

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.
