Warming alters mountain plant’s sex ratios

Mid-elevation male-female balance now shifted to higher altitudes, study finds

Valerian plant

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.
