Scientist has been counting California butterflies for 47 years and now sees them disappearing

By Deborah Netburn 12 November 2019 DONNER PASS, California (Los Angeles Times) – Art Shapiro stands on the edge of a Chevron gas station in the north-central Sierra, sipping a large Pepsi and scanning the landscape for butterflies. So far he’s spotted six species — a loping Western tiger swallowtail, two fluttering California tortoiseshells, a […]

The Trump administration didn’t like my agency’s research. So it sent us to Missouri. – “They can’t tolerate it when scientists present hard truths they don’t like”

By Andrew Crane-Droesch 21 October 2019 (The Washington Post) – I joined the Economic Research Service (ERS) in 2016. I wanted to use my academic training to do something in the public interest — I didn’t really expect to get involved in agriculture. Then I got absorbed in the subject: Humanity’s dependence on the environment […]

Billions face food, water shortages over next 30 years as nature fails – Study paints “a deeply worrying picture of the societal burdens of losing nature”

By Stephen Leahy 10 October 2019 (National Geographic) – As many as five billion people, particularly in Africa and South Asia, are likely to face shortages of food and clean water in the coming decades as nature declines. Hundreds of millions more could be vulnerable to increased risks of severe coastal storms, according to the first-ever model […]

Synchronous fireflies light up the Smoky Mountains. In this 345-second time-lapse exposure, fireflies blink through the woods during the Elkmont Fireflies viewing event at Elkmont Campground in Great Smoky Mountains National Park, Tennessee on Friday, 31 May 2019. The "Photinus carolinus" firefly is the only species in America that can synchronize their light patterns as part of their annual mating ritual. Photo: Calvin Mattheis / News Sentinel

Fireflies are dying out because people are destroying their habitats

By Dan Radel 31 July 2019 (Asbury Park Press) – Blink and you’ll miss one. Collecting fireflies is a childhood memory that many of us share. Their glowing lights begin to appear in the twilight around the time school ends each year, signaling the start of summer vacation.  But is the fire going out?     Researchers and advocates say the insect is […]

Pesticide exposure causes bumblebee flight to fall short – “The negative effects of pesticide exposure on flight endurance have the potential to reduce the area that colonies can forage for food”

By Hayley Dunning 30 April 2019 (Imperial College London) – Bees exposed to a neonicotinoid pesticide fly only a third of the distance that unexposed bees are able to achieve. Flight behaviour is crucial for determining how bees forage, so reduced flight performance from pesticide exposure could lead to colonies going hungry and pollination services […]

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

Decades-long butterfly study shows 33 percent population loss – “These declines in abundance are happening in common species”

By Steve Lundeberg 2 July 2019 CORVALLIS, Oregon (Oregon State University) – The most extensive and systematic insect monitoring program ever undertaken in North America shows that butterfly abundance in Ohio declined yearly by 2%, resulting in an overall 33% drop for the 21 years of the program. Though the study was limited to 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).

Nearly 40 percent decline in honey bee population last winter “unsustainable” – Trump administration cuts funding for bee research

By Julia Jacobo 9 July 2019 (ABC News) – Scientists are researching the potential consequences of the rapid decline of the honey bee population in the U.S. and how to mitigate its effects before it causes dire problems for crop management and production. Honey bees are essential for the pollination of flowers, fruits and vegetables, and support about $20 […]

Insect apocalypse: German bug watchers sound alarm – “Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades”

By Daphne Rousseau 1 July 2019 (AFP) – For almost 30 years they passed as quirky eccentrics, diligently setting up their insect traps in the Rhine countryside to collect tens of millions of bugs and creepy crawlers. Now the group of German entomology enthusiasts can boast a world-class scientific treasure: evidence of what is described […]

Deltoid spurge, shown here in 2005, is one of the endangered plants found only on pine rockland. The pine rockland found near Zoo Miami is the largest intact tract outside Everglades National Park. A 2015 study found 55 plant species in the tract, far more than botanists found in rockland in the park. Photo: Donna E. Natale Planas / Miami Herald

Activists lose last legal battle to protect rare Miami forest from Walmart development

By Adriana Brasileiro 19 June 2019 MIAMI (Miami Herald) – Activists fighting to preserve a slice of one of the world’s rarest forests lost what was likely the last legal battle to stop the imperiled ecosystem from turning into a Walmart-anchored development. One of the last remnants in Miami-Dade of pine rockland, a forest that […]

“Decimated”: Germany’s birds disappear as insect abundance plummets 76 percent

By Morgan Erickson-Davis 27 October 2017 (Mongabay) – A new study in PLOS ONE reveals a 76 percent reduction in Germany’s flying insect biomass over the past 27 years while another reports the country’s bird abundance has declined 15 percent in just over a decade. While the causes behind the insect decline haven’t yet been […]
