Study shows that echolocation frequency and wing shape of bats evolve in unison, which leads to distinct ‘foraging syndromes’ adapted to different environments. Bats are an evolutionary success story. With approximately 1,400 species living today, they thrive in every environment except the polar
Researchers found that echolocation frequency and wing shape in bats evolve together, leading to distinct “foraging syndromes” for different environments. Bats’ wing shapes and echolocation calls align with their hunting and habitat preferences, suggesting that these traits are evolutionary responses to specific ecological needs.
“Here we show that among bat species, there is a close correspondence between wing shape and the frequency of their echolocation vocalizations. This pattern wasn’t found in earlier studies because it’s hidden among the variation due to family,” said Dr.
Corresponding author Dr. Jiang Feng, a professor at Northeast Normal University, said: “Our results show that peak frequency and wing shape are linked: for example, bat species that hunt in open spaces tend to have long, pointed wings, and to produce long echolocation calls of low frequency.”
