Warming alters mountain plant’s sex ratios
Mid-elevation male-female balance now shifted to higher altitudes, study finds
MOUNTAIN CLIMBER Male valerian plants like this one have moved up in elevation in response to hotter, drier climate conditions. As a result, male-female plant ratios have changed since the late 1970s, researchers have found. This plant is growing in the research team’s highest study site, at 3,790 meters.
