Foxgloves brought by English to the Americas changed shape for hummingbird pollination

Study finds rapid evolution in foxgloves pollinated by hummingbirds

Weed invaders are getting faster

Weed invaders are getting faster

 E-Mail Dr Daniel Montesinos is a Senior Research Fellow at the Australian Tropical Herbarium, at James Cook University in Cairns. He is studying weeds to better understand (among other things) how they might respond to climate change. He said most invasive plants are characterised by their rapid pace when it comes to taking up nutrients, growing, and reproducing - and they re even faster in the regions they invade. New experiments comparing populations from distant regions show a clear trend for already-fast invasive plants to rapidly adapt even faster traits in their non-native regions, Dr Montesinos said. This is further pronounced in the tropics and sub-tropics.

New research reveals the resilience of Scots pine trees to drought

The effect of extreme drought on Scots pine trees has been examined as part of a University of Stirling study, which could have implications for climate change efforts across the world. The research – led by Tom Ovenden of the Faculty of Natural Sciences and published in the British Ecological Society’s Journal of Ecology – considered how resilient Scots pine trees are to extreme drought events. Scots pine is the cornerstone of Scotland’s Caledonian pinewoods and is a critically important species, both ecologically and economically, in the UK and across Europe. The new research provides a significant understanding of its vulnerability to, and recovery from, drought – a particularly important topic as drought events are expected to increase in intensity, duration, and frequency due to climate change.
