88 percent decline of big freshwater animals over 40-year period – “The results are alarming and confirm the fears of scientists involved in studying and protecting freshwater biodiversity”

By Nadja Neumann 8 August 2019 (IGB) – Rivers and lakes cover just about one percent of Earth’s surface, but are home to one third of all vertebrate species worldwide. At the same time, freshwater life is highly threatened. Scientists from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and international colleagues have now […]

Brazil’s Amazon deforestation surge is real, despite President Bolsonaro’s denial – Brazil environmental agencies and deforestation controls “effectively dismantled”

By Philip M. Fearnside 29 July 2019 (Mongabay) – Brazil’s Amazonian deforestation in June 2019 was 88 percent greater than for the same month in 2018, and deforestation in the first half of July was 68 percent above that for the entire month of July in 2018. There is no reason to question INPE’s current deforestation numbers from the DETER (Detection […]

By Stephanie Wood 18 July 2019 (National Observer) – The federal government has turned down an emergency recommendation from scientists to use a federal law to protect endangered trout that live along the path of the existing Trans Mountain oil pipeline and its expansion project. The decision — described by one First Nations chief, Lee […]

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 […]

The silent proliferation of small dams in the Amazon rainforest

By Francy Nava 6 July 2019 (Imazon) – Recent land cover mapping in Amazonia has identified a considerable number of water mirrors in rural properties, indicating the presence of small dams supporting agricultural activities. In Sorriso-MT, for example, Arvor, et al., (2018) identified a five-fold increase in the number of dams (86 to 522) in […]
