This study investigates the biogeography and niche evolution of Astragalus, finding that chromosome number correlates with diversification, central Asia as the origin, and soil and temperature divergence between hemispheres.

FloraTraiter automates extraction of plant trait data from biodiversity literature with high accuracy, enabling large-scale open-source trait dataset creation.

This study uses phylogenomic data to show widespread gene flow and reticulation during the early radiation of oaks and related genera.

This study quantifies phylogenetic diversity and distribution patterns of Fagales to understand drivers of temperate forest biomes.

This study reconstructs the diversification history of Fagales using a fossil-aware phylogenetic approach, finding older divergence times and highlighting the impact of fossil inclusion on biogeographic and diversification estimates.

The paper creates a comprehensive tetrapod trait database using phylogeny-informed imputation, revealing data gaps and biases in trait distribution across species.

The paper tests environmental determinants of nitrogen-fixing symbioses using phylogenetic analysis and finds RNS is linked to warm, arid, and nitrogen-poor habitats but not directly responsible for diversification.

This study identifies climatic factors driving hybridization in Heuchereae by analyzing phylogenetic data and paleoclimatic records.

The paper reconstructs the evolutionary history of root-nodule symbiosis in the nitrogen-fixing clade, identifying a two-step process involving shifts in evolutionary lability that explain multiple independent gains and losses of the trait.

This study compares spatial phylogenetic patterns of butterflies and flowering plants in North America, finding divergent biodiversity patterns and suggesting differences in habitat conservation.

The paper reports the plastid genome of Saniculiphyllum guangxiense, revealing extensive pseudogenization of photosynthesis-related genes despite its fully photosynthetic lifestyle.

The paper estimates large-scale phenological trends using iNaturalist photographs and compares them with Phenocam data, showing alignment across years and latitudes.

The paper develops best practices for using iNaturalist citizen science data to assess plant flowering phenology, demonstrating its utility for studying unusual flowering events and integrating data into a global knowledge store.

This study examines how incomplete sampling affects diversification rate estimates in rosids and finds that no method is fully robust to poor sampling, with BAMM being least sensitive to moderate missing taxa.

The paper constructs a five-locus supermatrix from GenBank data to explore rosid phylogeny, finding improved resolution but also highlighting sampling biases and limitations in current data.

This paper compares purpose-built and synthesis phylogenies for community phylogenetic analyses, finding synthesis trees yield comparable results with less effort.

The paper develops novel methods to reconstruct ancient hybridization in Heuchera by integrating dispersal-based biogeography and habitat suitability shifts.
