Genetic variation in age-dependent resistance to disease in three wild plant species, by Emily Bruns et al.…

Pollination in a drier world: Even moderate drought alters floral scent

Coline Jaworski discusses her recent paper: Long-term experimental drought alters floral scent and pollinator visits in a Mediterranean plant community despite overall limited impacts on plant phenotype and reproduction. Find out more about how drought can affect floral scent and the implications of climate change for pollination. Everyday, climate change is more present and dramatic…

Cover stories (110:8): Erythronium americanum, the Yellow trout lily

The cover image for our August issue features an Erythronium americanum leaf (the Yellow trout lily). This image relates to the research article: Citizen science across two centuries reveals phenological change among plant species and functional groups in the Northeastern US, by Kerissa Fuccillo Battle et al. Here, Kerissa tells us the story behind the image. This photograph shows…

Looking at shrubs (more) carefully: epigenetic mosaicism boosts variance of offspring traits

Carlos M. Herrera, Mónica Medrano and Conchita Alonso discuss their recent paper: Ecological significance of intraplant variation: Epigenetic mosaicism in Lavandula latifolia plants predicts extant and transgenerational variability of fecundity-related traits. Plants are nonunitary entities Charles Darwin emphasized long ago that, given the constellation of features which set them apart, terrestrial plants and animals are…

Genetic changes in New England Cichorium intybus since Thoreau’s times

Tomáš Závada discusses his recent paper ‘Radical shift in the genetic composition of New England chicory populations‘. Find out more about how genetic diversity and structure of Cichorium intybus populations have changed over time and the importance of herbarium specimens in this discovery. Herbarium collections represent a goldmine of botanical data. These days, herbarium specimens…

How abiotic context affects plant invasions mechanisms

Mariana Chiuffo discusses her recent paper: ‘Importance of invasion mechanisms varies with abiotic context and plant invader growth form‘. You can also read this blog post in Spanish here. Human activity has caused an unprecedented geographic reorganization of non-native plants. At a global level, 3.9% of vascular plants have become naturalized somewhere else (van Kleunen…

How is polyploidy affecting the evolution and diversity of plant functional traits? the case of Dianthus broteri complex

Javier López-Jurado discusses recent article: Polyploidy promotes divergent evolution across the leaf economics spectrum and plant edaphic niche in the Dianthus broteri complex. Find out more about role of polyploidy – the state of having more than two paired sets of chromosomes – in overcoming constraints for the evolution of plant functional traits. Major functional traits in…

Cover stories: Impacts of snowmelt & species interactions on plant population dynamics

The cover image for our May issue features a female Broad-tailed Hummingbird (Selasphorus platycercus) visiting flowers of the plant Ipomopsis aggregata in Gothic, CO, USA. This image relates to the research article: Comparative impacts of long-term trends in snowmelt and species interactions on plant population dynamics, by Diane Campbell, Mary Price, Nickolas Waser, Rebecca Irwin,…

Cover stories: Ginkgo biloba

The cover image for our April issue shows the diversity of leaf morphology from the fallen leaves of a single Ginkgo biloba tree, located in monitored plots at the Zijingang Campus, Zhejiang University, China. The image relates to the International Biological Flora: Ginkgo biloba, by Han-Yang Lin et al. ✏️A note from the Editor, Anthony Davy: The April cover…
