Study finds elephants plant trees, play big role in forest structure

Abstract: "Many large animals – collectively called “megafauna” – eat the fruit of Platymitra macrocarpa trees, including Asian elephants (Elephas maximus), sambar deer (Rusa unicolor), bears and gibbons. When researchers examined the fruit consumption, seed dispersal, and seed germination trends of P macrocarpa, they discovered that elephants were responsible for the lion’s share of successful seedling germination – 37 percent – despite consuming only 3 percent of available fruit. They also noticed a decline in P macrocarpa, which they say may be due to extirpated rhinos or reductions in local elephant populations. They say their results highlight the important role large herbivores play in forest structure, and that losses of these animals might significantly change tree composition and even a forest’s ability to store carbon."
