For the photographers or the ardent travellers who visit this blog I need to tell you that the BBC has featured the work of German artist/photographer Frank Thiel and his study of glaciers in Patagonia.
The works are currently on display at a gallery in New York City and are very large in order to convey a sense of scale.

How interesting could it be to read a book solely about different tree species? The answer — for anyone curious about the various facets of nature — is: Intensely!
This book not only makes clear its author’s encyclopaedic knowledge of his subject but is also written with an eloquence we no longer tend to witness. In other words, rather than even remotely being dry or boring, this book is both fascinating and an absolute delight to read. [EW]
The e-book ‘Lybrary’ review of A Natural History of North American Trees is no exaggeration and reads as follows:
“‘A volume for a lifetime’ is how The New Yorker described the first of Donald Culross Peatie’s two books about American trees published in the 1950s. In this one-volume edition, modern readers are introduced to one of the best nature writers of the last century. As we read Peattie’s eloquent and entertaining accounts of American trees, we catch glimpses of our country’s history and past daily life that no textbook could ever illuminate so vividly.
“Here you’ll learn about everything from how a species was discovered to the part it played in our country’s history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England’s white pines, which made the best tall masts for fighting ships.
“It’s fascinating to learn about the commercial uses of various woods — for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon’s portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed.
“A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man’s nature, he reports sorrowfully on the greed and waste that have doomed so much of America’s virgin forest.”

Small tortoiseshell butterfly (Aglais urticae) on barley – Tim Melling – Butterfly Conservation
Farmland butterflies have flourished thanks to last year’s hot summer, the charity Butterfly Conservation says.
The annual Wider Countryside Butterfly Survey (WCBS) recorded almost double the number of insects compared with the previous year.
Long, sunny periods provided perfect breeding conditions for some of the UK’s brightest species, it suggested.
But experts warned the mild winter could reverse the insects’ fortunes if they emerged too early for spring.
The survey has been run by Butterfly Conservation, the British Trust for Ornithology [BTO] and The Centre for Ecology and Hydrology since 2009….

Eddie’s comment: This is excellent news! For the past few years, there has been a dismaying scenario of butterfly numbers falling, throughout Britain. This has largely been attributed to inappropriately long periods of cold and/or wet weather, so it is nice to see that a warmer, drier summer brought numbers back up, perhaps to a larger extent than one might have dared hope.
As for the excellent photograph by Tim Melling, some experts say that the European Small Tortoiseshell (Aglais urticae) is actually the same species as North America’s “Milbert’s Tortoiseshell” (Aglais milberti).*
The other two North American tortoiseshells (‘California’ and ‘Compton’) are in a different genus — Nymphalis — the same as the Mourning Cloak.

An article published today in Britain, by the BBC, under the heading of ‘Bumblebees infected with honeybee diseases’, might not seem to be cause for alarm among nature lovers in America, but there can be no doubt that it is.

Given that bees are a massive factor in the viability not only of the wild flowers that we all enjoy but also of many important food crops, the rise of Deformed Wing Virus [DWV] and of the microsporidian ‘Nosema ceranae‘ should be of concern to anyone who has an interest in the health of our environment, and not least to bee keepers, whose livelihoods are once again being threatened.
When I read the above article, I did a search for these two problems in the USA, and sure enough I found this this report from the American Society for Microbiology, about DWV here in the States.
As for the ‘Nosema ceranae‘, Wikipedia has plenty to tell us about the spread of this pathogen, not only in the Americas but worldwide.

Canada’s Great Bear Rainforest is the largest temperate rainforest in the world. This huge and pristine wilderness depends on an unlikely source for its long-term survival – the salmon which spawn in its rivers and creeks….
In the linked video (see below), ecological economist Pavan Sukhdev, The Nature Conservancy’s lead scientist Dr M Sanjayan and camerawoman Sophie Darlington talk about the salmon’s unsung role in fertilising the forest. The bears who feast on the spawning salmon don’t eat on the river – they drag the carcasses far into the forest. The remains of the salmon contain vast quantities of nitrogen that plants need to grow. Eighty percent of the nitrogen in the forest’s trees comes from the salmon. In other words, these ocean dwellers are crucial for the forest’s long-term survival.
