Climate change profoundly impacts plant communities, for example, by changing the geographic range of some species and locally extinguishing others. Yet these changes take time, maybe a few years, to be observed. This lag between climate and plant communities changes could result from the soil seed bank…

As an educator, I reply on metaphors and stories to engage my readers, yet the line between hyperbole and engagement is thin. The concept of plant-plant communication is exciting, and certainly has some truth, but unfortunately has spilled over into a narrative that perhaps is more fiction than fact.…

Many plants have gone extinct in their natural habitat, but persist as samples preserved in herbaria around the globe. The existance of these samples raises questions about the possibility of using them to "bring back to life" these species, for example, by germinating the seeds or spores available in…

Seed dispersal is a critical ecological process with far-reaching implications. On rare occasions, seeds can be dispersed over vast distances, far beyond the range of the species. These events, known as long-distance dispersal, have profound evolutionary implications by expanding species distribution…

Many animals, including humans, tangibly benefit from living socially. Does this benefit extend to plants? A recent study by Höckerstedt et al. says it does. The authors studied a wild host-pathogen population, Plantago lanceolata, and its obligate powdery mildew pathogen Podosphaera plantaginis in…

Review: Seed sourcing strategies for ecological restoration under climate change "The local is best" is a mantra in ecological restoration: if you want your project to succeed, you should use local plant material since it's already adapted to local conditions. However, ecosystems now need to withstand…

“Grassy biomes—from the steppes of Mongolia to the savannas of Tanzania— are predicted to be the ecosystems hardest hit by the ongoing climate and land use crises,” begins a Perspective by Strömberg and Staver in the August 4, 2022 Science special issue on Grasses that raises awareness of the…

Are modern agricultural practices good for the environment? Or at least for the crops? If we look at a small field at a particular time point, it may seem they are good. But looking at a broader picture gives a different notion. In a recent study, Edlinger et al. collected 210 soil samples from traditional…
