Herbivores help prevent African savannah from becoming a forest
Grazing herbivores play a major role in maintaining savannah landscapes, say scientists.
Evolution of Himalayan flowers sheds light on climate change
Flower colour in some parts of the world, including the Himalayas, has evolved to attract bees as pollinators, research has shown for the first time.
Glacial history affects shape and growth habit of alpine plants
During the Ice Ages the European Alps were covered by a thick layer of ice. Climate fluctuations led to great changes in the occurrences of plants: They survived the cold periods in refugia on the periphery ...
New research explores theories about aging and death in plants
(Phys.org) —According to Benjamin Franklin, "nothing can be said to be certain, except death and taxes." But what if Franklin had it wrong—at least about death? University of Georgia ecologist Richard P. Shefferson explored ...
Chronic harvesting threatens tropical tree

Caribou the missing piece of arctic warming puzzle
In the first study of its type in Canada, new research has shown caribou have a role to play in climate warming in the arctic. Despite declining herd numbers, caribou grazing is controlling plant growth in ...
Exotic plants do not necessarily become invasive
Introduced plant species do not necessarily have to outgrow indigenous plant species. That makes it difficult to predict the potential harm of exotic plants. NWO-funded researcher Annelein Meisner recently published an article ...
