As consumers begin to demand the use of Social Plastic in the products they buy, the value of Social Plastic will increase. The more we can increase the value of Social Plastic world-wide, the less plastic will be discarded, and the more we can reward the people who need it the most.
Help us make plastic waste too valuable to throw away. This is the only sustainable way to prevent plastics from entering the ocean.

Tiny plants ride on the coattails of migratory birds: Migrant birds may be virtual dispersal highways for plants -- ScienceDaily
sciencedaily.com

Since the days of Darwin, biologists have questioned why certain plants occur in widely separated places, the farthest reaches of North American and the Southern tip of South America but nowhere in between. How did they get there? An international team of researchers have now found an important piece of the puzzle: migratory birds about to fly to South America from the Arctic harbor small plant parts in their feathers.

Lowest Temperature At Which Life Forms Can Live and Grow Pinpointed

From planetearth.nerc.ac.uk -August 29, 2013 12:03 AM

The study, published inPLoS One, reveals that below -20°C, single-celled organisms dehydrate, sending them into a vitrified – glass-like – state during which they are unable to complete their life cycle.

The researchers propose that, since the organisms cannot reproduce below this temperature, -20°C is the lowest temperature limit for life on Earth.

Scientists placed single-celled organisms in a watery medium, and lowered the temperature. As the temperature fell, the medium started to turn into ice and as the ice crystals grew, the water inside the organisms seeped out to form more ice. This left the cells first dehydrated, and then vitrified. Once a cell has vitrified, scientists no longer consider it living as it cannot reproduce, but cells can be brought back to life when temperatures rise again. This vitrification phase is similar to the state plant seeds enter when they dry out.

'The interesting thing about vitrification is that in general a cell will survive, where it wouldn't survive freezing, if you freeze internally you die. But if you can do a controlled vitrification you can survive,' says Professor Andrew Clarke of NERC's British Antarctic Survey , lead author of the study. 'Once a cell is vitrified it can continue to survive right down to incredibly low temperatures. It just can't do much until it warms up.'

More complex organisms are able to survive at lower temperatures because they are able to control the medium the cells sit in to some extent.

'Bacteria, unicellular algae and unicellular fungi – of which there are a huge amount in the world-are free-living because they don't rely on other organisms ,' Clarke explains.

'Everything else, like trees and animals and insects, has the ability to control the fluid that surrounds their internal cells. In our case it's blood and lymph. In a complicated organism the cells sit in an environment that the organism can control. Free-living organisms don't have this; if ice forms in the environment they are subject to all the stresses that implies.'



If a free-living cell cools too quickly it would be unable to dehydrate and vitrify; instead it would freeze and wouldn't survive.

This goes some way towards explaining why preserving food using deep freezing works. Most fridge freezers operate at a temperature of nearly -20°C . This study shows that this temperature works because moulds and bacteria are unable to multiply and spoil food.

'We were really pleased that we had a result which had a wider relevance, as it provided a mechanism for why domestic freezers are as successful as they are,' Clarke says.

The scientists believe that the temperature limit they have discovered is universal, and below -20°C simple forms of unicellular life can't grow on Earth. During the study they looked at a wide range of single-celled organisms that use a variety of different energy sources, from light to minerals, to metabolise. Every single type vitrified below this temperature.

Describe a bird accurately by using standard names for each part of its body.

Describe a bird accurately by using standard names for each part of its body. 

Bird feet have many specializations. For example, perching birds have a tendon locking mechanism in their feet that helps them hold on to the perch when they are asleep. Aquatic birds have webbed feet used for efficient propulsion through the water. Birds of prey have sharp talons on the ends of their feet which they use for capturing and killing their prey. The male emperor penguin's feet are specially shaped so that he can hold an egg on top of them as he covers it with his body to keep it warm. The ostrich has just two toes on each foot (most birds have four), with the nail of the larger, inner one resembling a hoof. The outer toe lacks a nail. This is an adaptation unique to Ostriches that appears to aid in running.

Identifying Birds - #FeederWatch

http://feederwatch.org/wp-content/uploads/2013/07/PosterEast.jpg
The Common Feeder Birds Poster (shown below), which participants receive in their project kit, features paintings of some common feeder birds arranged by size, shape, and color. Mini versions of the poster are available for download free.
Most people run for a field guide when they see an unfamiliar bird, even those of us who know better. The best thing to do is to quickly write down everything you can remember about the bird, preferably while you are still looking at it. 
Draw a quick sketch that allows you to point to different parts of the bird and label colors or features. For example, point to the top of the head and write down any coloring you observed on the head. Having the sketch will help you think of all the different parts of the bird to describe.

Welcome to the Aviary

An illustrated guide to more than 70 wild birds of Britain's mountains, lowlands, rivers, lakes and shores, plus a selection of beautiful birds from other parts of the world. These pages are intended for newcomers to birdwatching, but we hope that experienced birders will enjoy the pictures of garden bird species, water birds (including seabirds andcountryside birds of Britain as well as a few of the beautiful birds from mainland Europe and further afield.

Each image links to a page containing larger pictures, bird identification guides and details of food, breeding, nesting and habitat requirements for each of the bird species shown here.

Full details of some of the finest nature reserves and other sites that are brilliant for birds and bird watching, visit our 'Best for Birds' page in the Wales Wildlife section...

British Garden Birds

British Garden Birds

Look out for fledgling birds. They often look very different to their adults and now is a good time to learn the differences, while they are side-by-side with their parents. For starters, look for young Robins, which don't have a red breast, Blue Tits, which are more yellowy, and Starlings, which are a plain drab brown.

Good morning, British Garden Birds is dedicated to helping garden birdwatchers to identify and enjoy the birds that visit their gardens, and to understand the birds' lives and behaviour.
