A groundbreaking study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished —doubling in numbers and growing larger. This unprecedented look into prehistoric reef communities shows how the loss of top predators cascaded through the entire food web, shifting the balance amongst coral reefs.

Have you ever wondered how city life affects animals like frogs? A new study reveals that urban Túngara frog tadpoles develop faster —but end up being smaller — than tadpoles from forests, probably resulting in smaller adults. This might be an adaptation to warmer urban puddles with fewer predators or to constantly changing environmental conditions in the city.
