Spatial overlap and phenotypic similarity predict hybridisation in birds

This study identifies phenotypic and spatial factors that predict hybridisation in birds, showing that similarity in traits and range overlap increase hybridisation likelihood.

Landscape heterogeneity as a main driver of avian population dynamics

This study examines how landscape heterogeneity and environmental factors influence bird population dynamics over 25 years in Poland, finding that long-term spatial constraints and habitat heterogeneity are key drivers.

Citizen science and detailed searches reveal widespread occurrence of hybrid-like Syrian x Great-spotted woodpeckers

The paper reports widespread hybridization between Syrian and Great-spotted woodpeckers across Europe, identifying hybrid forms and their distribution patterns.

The cost of data aggregation: spatiotemporal compression obscures causal attribution in biodiversity monitoring

This study shows that aggregating spatiotemporal biodiversity data reduces causal inference accuracy, with full-resolution models outperforming compressed time series and distribution models.
