Wet and bulky cattle dung is very unlike marsupial dung that Australian dung beetles are adapted to deal with, meaning native dung beetles tend to leave it alone. But help from abroad is at hand.
A new study finds 70% of Amazonian dung beetles were killed by the severe fire and droughts of 2015 to 2016. By spreading seeds and poop, dung beetles fertilize forests and aid regrowth of vegetation.
How can the same basic genome produce such different forms in the two sexes of a single species? It turns out one gene can encode for various things, depending on the order its instructions are read.
Dung beetles have been cleaning up the planet for at least 65 million years. The 6000 species across the world have adapted to a life at the back end of the food chain in the most remarkable ways.
