Canopy beetles and flowering trees rely on each other in the Amazon, study
Held aloft by a canopy crane nearly 10 stories above the forest floor, Susan Kirmse observed and collected beetles in the rainforest canopy for an entire year. What did she find? Amazonian treetops are crawling with beetles, and they love little white flowers. As part of her Ph.D. research for Leipzig University, Germany, Kirmse collected 859 species of beetles (6,698 individuals) from the canopies of 23 different tree species in a healthy lowland tropical rainforest in southern Venezuela in the late 1990s. The Surumoni Crane in Venezuela allowed Kirmse to collect beetles from the rainforest c...
‘CSI Amazon’: Epic study looks at what’s killing Amazon trees
As more trees die in the Amazon Basin, the forest’s capacity to absorb carbon dioxide weakens. However, the main drivers of tree death across the region have been largely unknown, until now.A newly published study in the journal Nature Communications provides insight into why trees die in the Amazon, and why the rate of tree death may be increasing.According to the study, the main risk factor explaining tree death is the mean growth rate of species. Faster-growing tree species tend to have shorter life spans, and thus record more deaths over a given period.As climate change progresses, these f...
