Orchard Losses 'Threaten Species'

Image
Use of few or no chemicals makes orchards good wildlife habitat
Traditional fruit orchards are vanishing from England's landscape - with serious consequences for wildlife, conservationists have warned.

The National Trust says 60% have disappeared since the 1950s, putting local varieties of apples, cherries, pears, plums and damsons under threat.

It is launching a £536,000 drive to reverse the decline of the orchards.

Their trees provide important habitats for species such as the noble chafer beetle and lesser spotted woodpecker.

The orchards - some with as few as five trees - also offer sources of pollen and nectar to bees, which are thought to be declining partly because of a lack of suitable food.

Pressure from commercial fruit growers has led many small-scale producers to develop their orchards or convert them to other uses.

Hopeless blend of hot air and hubris

The ancient Greeks invented the idea of hubris, of human beings having overweening pride and self-esteem that needed to be punished for its excess. There are perhaps those who believe that what is commonly called climate change is a punishment for hubris, for human beings having gone beyond their place in the scheme of things.

However, an equally good case can be made that the call for human beings to make far-reaching changes to their way of life in response to climate change is itself a form of hubris. To begin, it is based on the belief that human endeavours, in the shape of industrial development, have had such an impact on the Earth that they threaten to disrupt its environment on an enormous scale. Not only have humans made such an impact on the planet, they are also capable, through an act of will, of reversing that impact and setting things right.

US: Myrtle Beach area fire still seething, but containment efforts are paying off

A study in contrasts, a pristine slate house on Woodlawn Drive stands in front of a landscape of charred trees and blackened soil.

The burned soil sits within 15 feet of the home's neat garden, and firefighters huddle near a truck watching the smoldering plumes, vigilant in case they should flare.

With a total of 76 homes destroyed in a wildfire that began Wednesday afternoon, emergency workers focused Saturday on continued containment and preventing refires.

At about 8 p.m. Saturday about 85 percent of the blaze was contained, said spokesman Scott Hawkins, with the state forestry commission. Most major roads except S.C. 31 have been reopened and all shelters have closed.

The reported number of acres damaged fell from about 20,500 acres to 19,600 acres Saturday due to better access to geographic informations system mapping data, Hawkins said.

US: Study documents new, rare creatures in Smokies

While most visitors to Great Smoky Mountains National Park have probably heard about the black bears that roam the park, few have heard about the water bears.

Known formally as tardigrades, water bears are microscopic, eight-legged creatures that exist in sediments and soils. Though they occur nearly everywhere on earth, few scientists have bothered to study the species.

That has left the field wide open for Paul Bartels, a biology professor at Warren Wilson College. Bartels and his students have discovered 78 species of tardigrades in the Smokies, including 18 new to science.

Institute director Gheorghe Marmureanu said it was felt in Bucharest, in the Black Sea port of Constanta, in the central city of Brasov, in the city of Iasi in northeast Romania, and at the port of Galati in easternmost Romania. It was also felt in Moldova which borders eastern Romania.

Swarm Savvy: How bees, ants and other animals avoid dumb collective decisions

Image
This is a phone conversation, so if Tom Seeley rolls his eyes, that's his business. He's a distinguished behavioral biologist, full professor at Cornell University, member of the American Academy of Arts & Sciences and so on. Yet he takes it pretty well when asked whether honeybees could have had a real estate crisis and crashed their banking system.

Seeley, at least voice-wise, stays polite and treats this as a serious question. Which it is.

Of course honeybees don't have a banking system, but they do exhibit collective behavior. The queen bee doesn't decide what the colony needs to do. Instead, each colony member does her or his bee thing, and out of hundreds or thousands of interactions, a collective decision emerges. Seeley's next book, due out in 2010, will be called Honeybee Democracy.
