Canada has been losing species for a long time

Since European settlement, over 100 species have been lost here. These include plants and animals that are extinct and extirpated, and species that are considered historic (no one has seen them in Canada for a long time). The number of lost species varies between different regions of the country. In the Great Lakes region of southern Ontario, there are extinct species (passenger pigeon), extirpated species (paddlefish) and historic species (Eskimo curlew). There are also species that have vanished from this landscape but still exist elsewhere in Canada.

Without Birds, Lizards, and Other Vertebrate Pollinators, Plant Reproduction Could Decline by Two-Thirds

Bees tend to get the most attention as pollinators critical to the survival of plant species. But lizards, mice, bats, and other vertebrates also act as important pollinators. A new study finds that fruit and seed production drops an average 63 percent when vertebrates, but not insects, are kept away from plants.

Bollenteelt in Drenthe neemt fors toe tot 1.900 hectare

Het areaal bloembollen was in 2017 vergeleken met 2000 met 18 procent gegroeid naar meer dan 26.000 hectare. Sinds 2000 is de bollenteelt in Drenthe ook flink gegroeid. Het areaal verviervoudigde bijna tot 1.900 hectare. Hiermee komt Drenthe, na Noord-Holland, Flevoland en Zuid-Holland, op de vierde plaats van provincies met het grootste areaal bloembollen. De plaats in Drenthe waar de meeste bollenteelt plaatsvindt is Midden-Drenthe met ruim 1.200 hectare. Westerveld staat met 323 hectare op de tweede plaats. Noord-Holland nam in 2017 het leeuwendeel van de bollenteelt voor haar rekening.

Die Zahl der weltweit bedrohten Tier- und Pflanzenarten hat dieses Jahr einen neuen Rekordstand erreicht

Mit rund 25'800 bedrohten Tier- und Pflanzenarten sei im zu Ende gehenden Jahr ein neuer dramatischer Höchststand erreicht worden. Ein Jahr zuvor waren es noch 24'000 bedrohte Arten. "Wir Menschen verursachen das grösste Artensterben seit Ende der Dinosaurier", resümierte Eberhard Brandes, Vorstand des WWF Deutschland. Auch in der Schweiz gingen die Bestände einiger Arten merklich zurück. Mehr als 40 Prozent der Insektenarten in der Schweiz gälten als bedroht, darunter Bienen und Schmetterlinge, sagte WWF-Sprecherin Perrette Rey in Lausanne auf Anfrage.

Hong Kong’s most endangered species

The black-faced spoonbill (Platalea minor) has the most restricted distribution of all spoonbills, and it is the only one regarded as endangered. There remain only about 3,300 spoonbills, and the species spends the mating season on small islands along the west coast of the Korean Peninsula and in China’s Liaoning province, the WWF says. “With such a small global population, the black-faced spoonbill is inherently vulnerable to extinction,” it says.

Paul Kirkland: How the plight of the butterfly may hit Scotland’s wild flowers

Much attention has been given to the plight of bees because of their importance as pollinators of major crops. But there is growing evidence that butterflies and moths – many of which have suffered dramatic declines in recent years – play an important role as specialist pollinators of some of our favourite wild flowers. A Swedish study recorded pollen on the bodies of three-quarters of butterfly species examined with some individuals carrying up to 350 grains.
