Urban vegetation data across 12 cities in northeastern North America

Stephanie A. Rivest, Simon Joly, Étienne Léveillé‐Bourret, Stéphanie Pellerin et autres

Data sets describing the composition of biological communities across broad anthropogenic gradients are valuable resources for ecologists and conservation biologists, with applications ranging from testing theories of community assembly to guiding biodiversity management. But much of the most rigorously collected field survey …

Blitz the Gap: a nation-wide effort to guide citizen science toward the needs of biodiversity science

Katherine Hébert, Nathan Earley, John Reynolds, Diane Srivastava et autres

To resolve persistent biases in conservation assessments and forecasting, we urgently need more systematic collection of biodiversity data. Citizen (or, community) science, despite its reputation for unstructured data, offers a particularly promising path forward, mobilizing participation at scales and speeds unmatched by …

Distinct genomic architectures but the same gene underlie the convergent evolution of a plant supergene

Giacomo Potente, Narjes Yousefi, Rimjhim Roy Choudhury, Stefan Grob et autres

Evolution reflects a balance between innovation and constraint, often repurposing existing components in new contexts. Convergent evolution exemplifies this interplay, with similar traits evolving independently in different species, yet the genomic mechanisms enabling such repeatability remain poorly understood. Here, by analyzing ten …

Clarifying the limits and geography of Limp and Ottawa Mannagrass ( Glyceria laxa and G . × ottawensis ; Poaceae)

Colin J. Chapman, Simon Pesant, Étienne Lacroix-Carignan, Sean Blaney et autres

Taxonomic uncertainty is an important challenge to biodiversity conservation, given that accurate status assessment and management decisions depends on sound species-level taxonomy and accurate distribution range maps. Glyceria laxa (Scribn.) Scribn. provides an excellent example. This wetland grass is rare in eastern …

Next‐generation specimen digitization: capturing reflectance spectra from the world's herbaria for modeling plant biology across time, space, and taxa

Jeannine Cavender‐Bares, Dawson M. White, Natalie Iwanycki Ahlstrand, Matthew W. Austin et autres

Spectral reflectance measured from herbarium specimens represents a potentially vast source of information relevant to plant taxon identification and functional traits, which has inspired many laboratories world-wide to initiate next-generation spectral digitization from specimens. Combining these datasets into a coordinated global database …

Spatio-temporal evolution of shrub willows (Salix subgenus Vetrix clade) on a global scale

Pia Marinček, Jing Vir Leong, Loïc Pittet, Étienne Léveillé‐Bourret et autres

• Salix species of the Vetrix clade group into four lineages that show a geographical pattern: The Pan-Himalayan clade, the North American clade, and two Eurasian clades. • Conflicting signals in the backbone and fine-scale relationships highlight the presence of reticulation in …

Genomic Patterns of Loss of Distyly and Polyploidization in Primroses

Emiliano Mora‐Carrera, Narjes Yousefi, Giacomo Potente, Rebecca L. Stubbs et autres

Transitions from outcrossing to selfing and from diploidy to polyploidy often co-occur in plants, likely because the ability to produce selfed seed increases the likelihood of newly formed polyploids to become established. An ideal system to study these transitions is Primula, where …

Fungal diversity notes 1919–2016: taxonomic and phylogenetic contributions to fungal taxa

Bin Cao, Dorji Phurbu, Anna B. Ralaiveloarisoa, Kare Liimatainen et autres

This article is the 18th contribution to the Fungal Diversity Notes series, in which we document 98 taxa across two phyla, eight classes, 21 orders, 46 families, and 59 genera. The represent samples of taxa were collected from a diverse range of …

Fate of a supergene in the shift from diploidy to polyploidy

Emiliano Mora‐Carrera, Narjes Yousefi, Giacomo Potente, Rebecca L. Stubbs et autres

ABSTRACT Despite the evolutionary importance of supergenes, their properties in polyploids remain unexplored. Polyploid genomes are expected to undergo chromosomal rearrangements and gene losses over time, potentially affecting supergene architecture. The iconic distyly supergene ( S -locus), controlling a floral heteromorphism with …
