New research led by scientists at the University of Bristol has uncovered that long-term use of some pesticides to treat cattle for parasites is having a significantly detrimental effect on the dung beetle population. Researchers studied 24 cattle farms across south west England and found that farms that used certain pesticides had fewer species of dung beetle. Dr Bryony Sands, from the University's School of Biological Sciences, who led the research, said: "Dung beetles recycle dung pats on pastures, bringing the nutrients back into the soil and ensuring the pastures are fertile.

Seit 14 Jahren ruft der NABU inzwischen Anfang Mai zu Vogelzählaktionen auf. In diesem Jahr waren die Menschen bundesweit von Vater- bis Muttertag dazu aufgerufen, die Vögel im heimischen Garten zu zählen. Bis zum vergangenen Montag konnten die Teilnehmer die Ergebnisse melden. Während sich die Veranstalter über die rege Beteiligung freuen - 53.000 Vogelfreunde haben sich zurückgemeldet - finden sie die Ergebnisse besorgniserregend. Denn unter den Top 15 der Gartenvögel weisen sieben Arten so geringe Zahlen auf wie noch nie.

Bird protection organisation Vogelbescherming has named 2018 the Year of the House Martin in an effort to call attention to the dramatic decline of this migratory bird in the Netherlands, public broadcaster NOS reports. Together with bird research group Sovon, Vogelbescherming has mobilised a group of volunteers to find the cause of the dwindling numbers of house martins (Delichon urbicum). Since 1970 some 80% fewer house martins have been spotted in this country and it is thought that since 1920 the decline could be as much as 95%.

Scientific research commissioned by Natuurmonumenten shows that the number of insects is declining dramatically in the Netherlands. Measurements and analyses in recent decades show a decline of 54 percent (ground beetles) and 72 percent (ground beetles) in nature reserves. This represents a dramatic fall in these groups of insects, which is in line with the results of recent German, French, English and Dutch studies. And this is bad, as it has a huge impact on the cycle of life.

Nineteenth-century poet John Clare wove together “descriptions of the environment and accounts of human life,” making no distinction between human and natural history. The anthropologists Richard D.G. Irvine and Mina Gorji argue that this makes him in some ways a poet of our current age, the Anthropocene. He drew connections between the reduction of insect life and the corresponding diminishment of the birds and mammals further up the food chain, essentially foretelling the dire environmental state we see today. Clare recognized an inherent value in land unconnected to human use.
