Plantae Presents - Evo-devo. What can we learn from comparative studies? Recorded Wednesday, October 28 - 10 am EDT We're pleased to announce the second in our series of webinars that are drawn from contributed short videos, followed by a panel discussion. This week we'll look at the topic of…

Author: Robert Skelton rskelton@saeon.ac.za Affiliation: South African Environmental Observation Network, Private Bag X7, Claremont, 7735, South Africa Knowledge of the spatio-temporal dynamics of water storage in plant stems is fundamental to understanding plant physiological function under…

Climate warming affects plant performance in warm and dry regions. In cold regions, warming stimulates growth and reproduction, but its effects can vary depending on location and species. Whether herbaceous plants can adapt to increasing temperatures is unclear and a matter of concern. In this study…

Since dispersal is crucial for the assembly of plant communities, a better understanding of its relation to climate is needed to predict plant communities' responses to changes in the environment. However, this kind of association is still missing in tropical alpine ecosystems –one of the most vulnerable…

Several studies have addressed growing concerns regarding increases in exotic plant colonization of communities in response to a warming climate. However, both abiotic (e.g., warming climate) and biotic (e.g., changes in community diversity) shifts can be simultaneous results of warming and both can…

Whenever we talk about global trends there are of course local variations. Here, Piao et al. discuss recent trends of global greening, which is occurring at arctic as well as temperate and tropical regions. Overall, this greening is attributed to increasing atmospheric CO2, which promotes plant growth,…

Much of our understanding of abiotic stress response comes from studies on short-lived annual plants, for good reasons: they are small and easy to study, their short-generation time makes them amenable to genetic studies, and most of our food comes from annual plants. Trees are more difficult to study,…

Crop yields are vulnerable to rising temperatures and changes in precipitation. Here, Gaupp et al. model the projected crop yields at 1.5 versus 2.0 degrees of additional warming, as part of the HAPPI experiment (perhaps a misnomer: Half a degree Additional warming, Prognosis and Projected Impacts).…
