Ohio statewide butterfly population trends of nine resident species with annual variation. Plotted are model predictions for each year based on the fixed effects of year (solid line) and annual random effects (dots) to show annual variation about the trend line. Shading shows 95 percent confidence intervals based on bootstrapped model fits in the poptrend package for the temporal trend and for the annual random effects. The first year’s estimate is set to a value of 1 as a baseline for relative population changes. Graphic: Wepprich, et al., 2019 / PLOS ONE

Total U.S. managed honey bee colonies loss estimates 2006-2019. For the entire survey period (1 April 2018 – 1 April 2019), beekeepers in the U.S. lost an estimated 40.7 percent of their managed honey bee colonies. This is similar to last year’s annual loss estimate of 40.1 percent, but slightly higher (2.9 percentage points) than the average annual rate of loss reported by beekeepers since 2010-11 (37.8 percent).

Hurtigruten’s cruise ship MS Roald Amundsen is seen in the sea near Ulsteinvik, Norway, on 1 July 2019. The Roald Amundsen is the world’s first cruise ship propelled partially by battery power and is set to head out from northern Norway on its maiden voyage, cruise operator Hurtigruten said on Monday. The hybrid expedition cruise ship can take 500 passengers and is designed to sail in harsh climate waters. Named after the Norwegian explorer who navigated the Northwest Passage in 1903-1906 and was first to reach the South Pole in 1911, the ship heads for the Arctic from Tromsø this week and will sail the Northwest Passage to Alaska before heading south, reaching Antarctica in October 2019.
