The boy asked his father, Tim Faulkner, “They’re all dying aren’t they Dad?” Faulkner told him it was his job to save the world. Photo: Tim Faulkner / Facebook

Estimated number of animals killed in Australia bushfires rises to more than one billion – “Events like this may well hasten the extinction process for a range of species”

8 January 2020 (University of Sydney) – Professor Chris Dickman has revised his estimate of the number of animals killed in bushfires in NSW to more than 800 million animals, with a national impact of more than one billion animals. Several weeks ago Professor Dickman, from the University of Sydney’s Faculty of Science, estimated that 480 […]

Nearly 500 million animals killed in Australia bushfires since September 2019 – 30 percent of koalas incinerated by “unfightable” fires in New South Wales – Thousands of fire-injured sheep shot on Kangaroo Island

By Marnie O’Neill 1 January 2020 (News.com.au) – There are concerns that entire species of plants and animals may have been wiped out by bushfires following estimations that 480 million animals may die as a result of the crisis. Ecologists from the University of Sydney estimate almost half a billion mammals, birds and reptiles may […]

All of the species declared extinct in the 2010-2019 decade – “The trends that connect these 160 extinctions are true of the biodiversity crisis more generally”

By Ryan F. Mandelbaum 16 December 19 (Gizmodo) – Lonesome George, the last of the Pinta Island tortoises, died in 2012. George’s story is the perfect extinction story. It features a charismatic character with a recognizable face, an obvious villain, and the tireless efforts of naturalists. The population of the Pinta Island tortoise species was […]

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 […]

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 […]
