The research, published in the British Trust for Ornithology (BTO) journal Bird Study, looked at the breeding populations of three species of large gull; Herring Gull (Larus argentatus), Great Black-backed Gull (Larus marinus) and Lesser Black-backed Gull (Larus fuscus) on the Hebridean island of Canna, and the relationship between these gull populations and the fall in the quantity of fish landed in the nearby harbour of Mallaig. Between 1985 and 2000 an annual average of 13,726 tonnes of fish was landed in Mallaig. However, between 2007 and 2014 this had fallen to 4,456 tonnes.
Despite a steady rise in the manufacture and release of synthetic chemicals, research on the ecological effects of pharmaceuticals, pesticides, and industrial chemicals is severely lacking. This blind spot undermines efforts to address global change and achieve sustainability goals. So reports a new study in Frontiers in Ecology and the Environment. Emma J. Rosi , a freshwater ecologist at the Cary Institute and a co-author on the paper, explains, "To date, global change assessments have ignored synthetic chemical pollution.
Wetlands constitute an important natural resource that is overlooked by many of us. When people think of wetlands, they tend to picture unpleasant landscapes, mosquitoes and strange smells, but they don’t see the handful of benefits these habitats provide for the ecosystem as a whole. These natural benefits often are translated into economic goods. When we look into all of the great things wetlands do for us, it is hard to deny that we can’t do without them. Wetlands play a key role in regulating water quality and availability in certain areas.
"Dead or dying herring found on shore should not be collected, consumed or used by the public for any reason, as a variety of factors could affect the food safety of fish, such as toxins, diseases or environmental contaminants", warned the Canadian Food Inspection Agency and the Department of Fisheries and Oceans in a statement. Officials are now testing for pesticide content and checking water oxygen levels, in hopes of getting to the bottom of the situation.
Eine erschreckende Bilanz hat unlängst NRW-Landesumweltminister Johannes Remmel vorgelegt: Rund 44 Prozent unserer heimischen Tier- und Pflanzenarten sind mittlerweile in ihrem Bestand gefährdet und haben somit einen unrühmlichen Platz auf der Roten Liste ergattert. Und am Niederrhein? Leider ist auch hier das Ergebnis katastrophal. Selbst in den meisten Schutzgebieten geht der Artenschwund signifikant weiter. Insbesondere auf landwirtschaftlich genutzten Flächen ist die Artenvielfalt in den letzten Jahren rapide zurückgegangen.
The World Wildlife Fund has released its 2015 Living Blue Planet Report, and it’s not looking good. The report tracks 5,829 populations of 1,234 mammal, bird, reptile, and fish species, which the Zoological Society of London then analyzed using “a marine living planet index.” The report’s most harrowing finding is that, between 1970 and 2012, the world’s marine vertebrate population declined by 49 percent. Just as troubling, however, is the rapid disappearance of their habitats. The remaining animals have fewer places to live, prosper, and breed.
The Caribbean's island geography makes it a highly biodiverse region. It is home to approximately 6,500 plant, 150 bird, 470 reptile, 40 mammal, 170 amphibian and 65 fish species not found anywhere else in the world. The global wildlife trafficking crisis threatens many of these species, which are used, often illegally, as pets, medicine, food, jewellery, clothing, souvenirs and household decorations.
In her recent Environmental Protection Report entitled Small Steps Forward, the Environmental Commissioner of Ontario, Dianne Saxe, called upon the government to put words into action to monitor biodiversity, combat wildlife declines, control invasive species, and follow through on better forest fire management. The large-scale loss of biodiversity is a crisis in Ontario and around the world. Ontario's most "at risk" species are snakes, turtles and freshwater mussels. However, many freshwater fishes, birds and mammals are also experiencing alarming declines.
The widespread adoption and use of neonicotinoid compounds originally considered to be environmentally benign can now potentially be considered to be an environmental catastrophe. While the generational development and production of neonicotinoids has focused on making these insecticides more potent to their target organisms at very small dosages, their adverse environmental consequences have largely remained overlooked. Imidacloprid was the first generation neonicotinoid to receive widespread attention for its environmental consequences.
De globale biodiversiteit zal in 2020 met 67% gekelderd zijn tegenover 1970, als de huidige trend zich voortzet. Dat zegt de nieuwe editie van het Living Planet Report (LPR) van WWF, dat vandaag werd voorgesteld in het Natuurhistorisch Museum in Brussel. Het rapport toont aan hoe de mens de aarde aan het overrompelen is op een nooit geziene manier in de geschiedenis van onze planeet. Mondiale populaties van vissen, vogels, zoogdieren, amfibieën en reptielen zijn nu teruggevallen met 58% tussen 1970 en 2012. We zijn getuige van een 6e massa-extinctie in wording.
