Titre : Tropical and desert grasses may migrate further south

The maximum summer temperature and the amount of rainfall in summer are the two climate factors that determine the type of native grass that grows in a region, Australian researchers have found in a recent study.

Présentation
A rise in global temperatures due to a change in climate may lead to tropical and desert grasses growing in different environments, which could have an impact on animals that rely on it as a food source. Warm-season grasses grow in hot, tropical or desert climates like northern and central Australia, while temperate or cool-season grasses primarily grow in southern Australia. The researchers analyzed data on the distribution of grass species collected from more than 800 plant surveys conducted across the country by the TERN Australia monitoring network.
