Pleistocene glaciation advances the younger temporal dimension of species diversification in a major biodiversity hotspot

The paper uses genomic and eco-morphological analysis to reveal recent diversification in the Stellera chamaejasme L. complex, driven by Pleistocene glaciation and biotic factors.

Phenologically-informed species distribution models (SDMs) forecast less species loss and turnover versus standard SDMs

The paper develops phenology-informed species distribution models that predict lower species loss and turnover under climate change compared to standard models.

Molecular analyses place the genus Keraunea outside Convolvulaceae

The paper uses molecular sequence data to reclassify the genus Keraunea from Convolvulaceae to Malpighiaceae and Ehretiaceae, despite morphological anomalies.

Herbarium records provide reliable phenology estimates in the understudied tropics

This study shows herbarium records provide reliable estimates of tropical plant phenology, matching field observations in reproductive timing and spatial variation.

PhyloHerb: A phylogenomic pipeline for processing genome skimming data for plants

PhyloHerb processes genome skimming data to assemble phylogenomic datasets, demonstrating accuracy with fragmented assemblies from herbarium specimens.

Herbarium specimens reveal herbivory patterns across the genus Cucurbita

This study uses herbarium specimens to analyze herbivory patterns across Cucurbita species, finding variation in damage levels and a link between habitat type and herbivory intensity.

Ecophysiological differentiation between life stages in filmy ferns (Hymenophyllaceae)

This study compares desiccation tolerance and physiological traits between gametophytes and sporophytes in filmy ferns, finding differences in water-stress strategies and niche requirements.

Back to the future: a refined single user photostation for massively scaling herbarium digitization

This paper introduces a novel photostation design for herbarium specimen digitization that improves efficiency and scalability for institutions of all sizes.

Re-examining Kozlov et al.: Estimation of biases in museum specimen data requires robust sampling

This paper re-analyzes Kozlov et al.'s study on herbarium specimen biases, finding that herbarium specimens can accurately represent herbivory when sample sizes are adequate, contradicting the original conclusions.

Phenological displacement is uncommon among sympatric angiosperms

The paper examines phenological displacement in flowering time among sympatric angiosperms and finds it is uncommon overall but more pronounced in species with similar flowering times.

A new method for counting reproductive structures in digitized herbarium specimens using Mask R-CNN

This paper develops a Mask R-CNN model to automate counting reproductive structures in herbarium specimens, achieving high accuracy for buds and fruits but lower for flowers.

The Perfect Storm: Gene Tree Estimation Error, Incomplete Lineage Sorting, and Ancient Gene Flow Explain the Most Recalcitrant Ancient Angiosperm Clade, Malpighiales

This study investigates the factors causing unresolved phylogenetic relationships in Malpighiales, finding that gene tree heterogeneity arises from incomplete lineage sorting, gene tree estimation error, and ancient gene flow.

Water lily (Nymphaea thermarum) draft genome reveals variable genomic signatures of ancient vascular cambium losses

The paper sequences the water lily Nymphaea thermarum genome and compares it to other plants to identify gene loss and divergence patterns associated with vascular cambium loss.

Freezing and water availability structure the evolutionary diversity of trees across the Americas

This study examines how freezing temperatures and water availability shape the evolutionary diversity of tree species across the Americas, finding phylogenetic niche conservatism as a key factor.

The unrealized potential of herbaria in global change biology

This paper highlights the underutilized potential of herbaria for global change biology, emphasizing their value in studying ecological and evolutionary responses to climate change and other biodiversity loss drivers.

Widespread ancient whole genome duplications in Malpighiales coincide with Eocene global climatic upheaval

The paper identifies 22 ancient whole genome duplications in Malpighiales, clustered around the Eocene-Paleocene Transition, supporting the hypothesis that WGDs aid plant survival during climatic upheavals.

Widespread sampling biases in herbaria revealed from large-scale digitization

This study identifies widespread sampling biases in herbarium records from three digitized floras, revealing shared and regional-specific patterns that may affect ecological and evolutionary conclusions.

Selfing species exhibit diminished niche breadth over time.

The paper examines climatic niche breadth and mutation accumulation in selfing and outcrossing plant species, finding selfers have narrower niches and higher mutation rates despite larger geographic ranges.
