Russia: Mass seal death likely due to oxygen deprivation

MOSCOW, 5 December 2022 (AP) – A top Russian environmental official said Monday that the thousands of dead seals that washed up on Russia’s Caspian Sea coast likely died from oxygen deprivation. Officials in the republic of Dagestan, which has a long coastline on the world’s largest inland body of water, said this week that […]

WWF’s Living Planet Report 2022 reveals devastating 69 percent average drop in wildlife populations since 1970 – “We have cut away the very foundation of life and the situation continues to worsen”

TORONTO, 12 October 2022 (WWF-Canada) – Monitored wildlife populations — mammals, birds, amphibians, reptiles, and fish — have seen a devastating 69 per cent drop on average since 1970 according to WWF’s Living Planet Report (LPR) 2022. The report highlights the stark outlook of the state of nature and urgently warns governments, businesses and the public to take […]

Last freshwater Irrawaddy dolphin in northeastern Cambodia entangled in fishing net and dies – Statue to be erected on bank of Mekong River to commemorate its existence

PHNOM PENH, Cambodia, 16 February 2022 (AP) – The last surviving freshwater Irrawaddy dolphin on a stretch of the Mekong River in northeastern Cambodia has died, apparently after getting tangled in a fishing net, wildlife officials said Wednesday. The aquatic mammal was found dead Tuesday on a riverbank in Stung Treng province, near the border […]

Two bird species that are extinct but not listed as such, for fear of committing the “Romeo Error”. Both species are still listed as Critically Endangered by IUCN because of the slim chance that one or more birds may still be alive. Such species are therefore not counted among extinct species, and vast sums of money are often spent in the vain hope that they will be found again.

Earth on trajectory to Sixth Mass Extinction say biologists – “Including invertebrates is key to confirming that we are indeed witnessing the onset of the Sixth Mass Extinction in Earth’s history”

By Marcie Grabowski 14 January 2022 (UH News) – Mass biodiversity extinction events caused by extreme natural phenomena have marked the history of life on Earth five times. Today, many experts warn that a Sixth Mass Extinction crisis is underway, this time entirely caused by human activities. A comprehensive assessment of evidence of this ongoing […]

WWF: Looming mass extinction could be biggest since the dinosaurs – “One million species could go extinct within the next decade, which would be the largest mass extinction event since the end of the dinosaur age”

29 December 2021 (DW) – Ever-growing environmental threats are pushing many animals and plants to the brink of extinction — the scale of which hasn’t been seen since dinosaurs died out, the German branch of the World Wildlife Fund (WWF) said on Wednesday. The stark warnings came as WWF Germany released its “Winners and Losers of 2021,” an annual […]

Spatial cumulative extents of the Deepwater Horizon (DWH) oil spill. (A) Cumulative NESDIS anomaly daily composites integrated from 20 April 2010 to 21 July 2010. Daily fishing closures are marked with gray lines; the cumulative fishing closure area is marked with a thick dashed yellow line. The black star represents the location of the DWH blowout. (B) Cumulative value of daily average oil concentrations (ppb), integrated across the same time span as (A) and across water depths. Vertical depth layers are 0 to 1 m, 1 to 20 m, and in 20-m increments down to 2500 m. Sediment and water samples with higher-than-background concentration are marked in bright green and dark blue circles, respectively. Red crosses in (B) represent approximate locations of DWH-related oil detections reported in previous studies. Daily fishery closures are marked with black polygons; the cumulative fishery closure area is marked with a dashed thick polygon. AB, Apalachee Bay; DP, Deep Plume; EFS, East Florida Shelf; FK, Florida Keys; LC, Loop Current System; TXS, Texas Shores; WFS, West Florida Shelf. (C) Categorization of the modeled oil spill are as follows: (i) nontoxic, PAH concentrations above background level and smaller than 0.5 and 1 ppb at the surface (depth, 0 to 1 m) and in the water column (depth, >1 m), respectively; (ii) toxic-to-biota and invisible, PAH concentrations 0.5 to 17 ppb at the surface and above 1 ppb in the water column; and (iii) toxic and visible, PAH concentrations above 17 ppb. In (C), categories were computed according to maximal concentrations across time. (D) Duration of toxic concentrations across the domain. (E) LC50 of 12 experiments examining the photoinduced toxicity to blue crab (31), fiddler crab (33), mahi mahi (29, 30), red drum (32), and speckled sea trout (32) (for more details, see table S2). (F) The spatial extent of the toxic concentrations from (E); color codes in (F) are according to bar colors in (E), representing concentrations exceeding LC50. In (F), toxic PAH of 0.5 ppb was concentrations were considered for surface waters only (depth, 0 to 1 m). Graphic: Berenshtein, et al., 2020 / Science Advances

The toxic reach of the Deepwater Horizon oil spill was much larger and deadlier than previous estimates – “Large areas of the Gulf of Mexico were exposed to invisible and toxic oil that extended beyond the boundaries of the satellite footprint and the fishery closures”

By Darryl Fears 12 February 2020 (The Washington Post) – The spread of oil from the Deepwater Horizon disaster in the Gulf of Mexico was far worse than previously believed, new research has found. As the worst offshore oil spill in U.S. history approaches its 10th anniversary in April, a study by two University of Miami researchers […]

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 […]

Snipers to cull up to 10,000 camels in drought-stricken South Australia

8 January 2020 (AFP) – Snipers took to helicopters in Australia on Wednesday to begin a mass cull of up to 10,000 camels as drought drives big herds of the feral animals to search for water closer to remote towns, endangering indigenous communities. Local officials in South Australia state said “extremely large” herds have been […]

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 […]
