Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Organic carbon determination in histosols and soil horizons with high organic matter content from Brazil

open access: yesScientia Agricola, 2006
Soil taxonomy systems distinguish mineral soils from organic soils based on the amount of soil organic carbon. Procedures adopted in soil surveys for organic carbon measurement are therefore of major importance to classify the soils, and to correlate ...

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Back Again to the Future: A New Era for Cerebroprotection

open access: yesAnnals of Neurology, EarlyView.
Cerebroprotection is a fresh framework for designing neurological therapy that targets glia and vascular cells, in addition to neurons. In the future, successful cerebroprotection will involve targeting all elements of the neurovascular unit. Preclinical trials must include functional outcomes, as well as lesion morphometry.
