Climate change favours weeds
A team of researchers led by ecologist Dr Helen Zempel at the University of Sussex has found evidence that weeds grow much faster and more efficiently when the climate is warmer.
The research has been published in the journal Global Ecology and Biogeography.
Dr Zempel said: “There is evidence to show that climate change has a strong tendency to favour weeds.
“We had some plants in our experiments that were grown in the shade, but even those that were growing in full sun tended to die back because they would not survive, so there is more variation in temperature among different locations.
“This could suggest that the temperature is also responsible for the effects we are observing.”

Other studies have found that the climate is a strong climatic trigger for weeds.
Professor Dr Ian Ritchie, one of those lead scientists, said: “The weed problem we’re facing is one of scale and the way that we control them and the environmental response to them is the way to scale up.
“This study’s finding that there is a direct correlation between plant population density and temperature and rainfall shows that climate change is an important factor in keeping grasses in check and therefore to combat pests, especially weeds.”
The study examined 14 Australian species of grasses, each with a range of temperatures from cool-dry to hot-high.
They were divided into two groups: plants that were growing in direct sunlight and those growing in shade to make them grow fastest in a cooler climate.
The researchers found that the weed groups which grew most quickly in a cooler climate were Caulerpa sativiflora (15%), Tettigoniopsis sp. (11%), Caulerp바카라a sp. (5%), Fusarium sp. (5%), and Gossypium alvarius (4%).
“The reason for the temperature differences between the two was because Caulerpa sativiflora prefers to grow with higher temperatures, whereas Tettigoniopsis sp. prefers to jarvees.comgrow with colder temperatures,” Dr Zempel explains.
“The study is consistent with previous research showing that temperature may be a factor in the control of plant growth, in particular over the hot seasons which are much hotter for our greenhouse plants.
