Male, female orangutans look to different mentors for sex-specific ecological knowledge

Male, female orangutans look to different mentors for sex-specific ecological knowledge

Science
May 19 (UPI) -- Young male and female orangutans look to different individuals for sex-specific ecological knowledge as they mature, according to new research. Often, studies of sexual differences focuses on mating behavior and social organization, but field observations suggest male and female orangutans also demonstrate sex-specific foraging and dispersal patterns. Advertisement To better understand how these behaviors are acquired, researchers analyzed 15 years worth of data on dietary and social learning behaviors exhibited by 50 young orangutans living among two different Sumatran populations. Scientists shared their findings Wednesday in the journal PLOS Biology. "In our study we showed that immature orangutans show sex specific attentional preferences when observing role models ot...

Blinded by the light: Birds lured into ecological traps by light pollution

Science
Jan. 19 (UPI) -- Humans aren't the only animal drawn to the bright lights of the big city. New research suggests urban light pollution attracts migrating birds, luring them into ecological traps.As birds in the Northern Hemisphere trek southward during the fall, they make stopovers en route to their wintering grounds. Most species travel from stopover to stopover at night. Scientists were able to use data from 16 weather surveillance radars to track the movements of migrating birds."Shortly after sunset, at around civil twilight, they all take off in these well-synchronized flights that show up as a sudden bloom of reflectivity on the radar," Jeff Buler, an ecologist at the University of Delaware, said in a news release. "We take a snapshot of that, which allows us to map out where they we...
