Prioritizing site groups for intrinsic biodiversity assets using complementarity and not just rarity

open access: yesConservation Science and Practice, EarlyView.
Conservation practitioners rightfully focus on at‐risk species when valuing biodiversity assets and prioritizing spatial units. We compared and combined numbers of at‐risk species with four other community metrics using surveys of vascular plants at wetlands in a preserve network in Illinois, USA.

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Evolutionary Imprints on the Foliar Elementome: Biogeochemical Niche Differentiation Among Fagus Species

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study compared the biogeochemical niches of three Fagus species (F. grandifolia, F. sylvatica, and F. crenata) using foliar nutrient data from 328 sites, revealing distinct elemental compositions and unique nutrient acquisition strategies. Phosphorus and calcium primarily distinguished F. sylvatica, whereas F.

Unearthing Forest History: Integrating Soil Charcoal Macrofossils and Pollen Reveals Delayed Forest Responses to Holocene Climatic Transitions in Boreal–Temperate Ecotone

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study reconstructs long‐term vegetation dynamics at the boreal–temperate forest ecotone in eastern Canada using soil charcoal, pollen records, and forest inventories. Results reveal a delayed expansion of thermophilous tree species and a late borealization of the landscape in relation to climate change, alongside recent stand‐scale shifts driven ...
