Posted Mon, 17 Jan 2011 08:50:00 GMT by Lynn ParrA new study shows that increasing water temperature in the North Sea is pushing zooplankton species further north, resulting in less food for young cod. Global warming will adversely affect the recovery of the Atlantic Cod in the North Sea, a new study shows.

Busy as bee? They need their rest too!
Posted Wed, 12 Jan 2011 08:29:00 GMT by Paromita PainIts not just humans but bees too need their rest. A recent study by the University of Texas at Austin shows that sleep-deprived honey bees also experienced communication problems. Dr. Barrett Klein, a ecology, evolution and behavior researcher at the university says that they advertised the direction to a food site less precisely to their fellow bees.

Family social stress affects children - even birds
Posted Mon, 10 Jan 2011 12:11:23 GMT by Michael EvansFranco-Austrian study indicates that stressed female birds can lay eggs that produce stressed chicks. The debate between nature and nurture first began in the mid-19th century when Charles Darwin's cousin, Francis Galton raised the question of whether hereditary or environmental factors were the prime influences with respect to social advancement.

How invasive species can trigger mass extinctions
Posted Fri, 07 Jan 2011 11:26:00 GMT by Michael EvansResearchers from Ohio suggest that human activity that is allowing the introduction of invasive species into ecosystems tcould potentially lead to the Eath's sixth mass extinction. 65 million years ago dinosaurs dominated the Earth. Global temperatures were between six and 14 degrees Celsius warmer than at present and sea levels were over 300 metres higher. 40% of the present land mass was under the sea.

Pesticides threaten social, ecological aspect of ant hunting in Brazil
Posted Fri, 07 Jan 2011 11:03:12 GMT by Paromita PainIçás, or queen ants in Brazil are a delicacy. Spring rains in October and November drive the ants out of the ground, and for a few short weeks. But this year pesticides have threatened the social and the ecological aspect of ant hunting. The principal culprits are pesticides used on eucalyptus trees that are planted to produce cellulose for paper and other products.

The Silvereye Learns to Shout Above Traffic
Posted Fri, 07 Jan 2011 09:12:46 GMT by Lynn ParrOne species of Australian bird, the silvereye, has been found to change its songs to compensate for lound traffic noise in urban areas. Some Australian birds are learning to shout to make themselves heard above traffic noise. The silvereye in urban environments have been found to sing higher-pitched but slower songs than those in rural areas.

Super Efficient Feeding Habits of Blue Whales
Posted Tue, 04 Jan 2011 09:56:54 GMT by Michael EvansA Canadian study to contrast the amount of energy a blue whale could expend during one dive, with the amount of energy it could get from the food it collected. As most people will know, the blue whale is the largest animal alive and probably the largest animal that has ever lived. When a blue whale calf is born it is as big as a fully-grown hippopotamus and during its first seven months it will drink about 400 litres of its mother's milk every day.

Bumblebee Paper by 8 to 10-year-olds published by Royal Society
Posted Wed, 29 Dec 2010 09:11:00 GMT by Paromita PainBiology Letters, a peer-reviewed journal of Britain's Royal Society, on Wednesday published a report (complete with colored-pencil diagrams) on how bumblebees see colors and patterns -- conducted and written by a group of 8 to 10-year-olds in Devon, England. They reported that the bees were capable of learning and remembering cues based on color and pattern -- a finding that the Royal Society called ''a genuine advance.''

Brown Bears versus Polar Bears
Posted Mon, 06 Dec 2010 10:11:00 GMT by Michael EvansThe bleak future for polar bears as global warming encourages brown bears to range further north. Something that is not widely realised is that polar bears only evolved as a distinctive species as recently as 200,000 years ago during the Pleistocene.

Tackling Global Wildlife Crime
Posted Thu, 25 Nov 2010 15:05:01 GMT by Emma McNeilAt this week's International Tiger Forum in Saint Petersburg an important alliance was formed that will help not just tigers but a range of endangered species across the globe. A Letter of Understanding signed at the Forum brings into effect the International Consortium on Combating Wildlife Crime (ICCWC).

We use the tiger (this is a prime Siberian example) to show up our failure to conserve wild species, but while we monopolise all the food that animals require, we could remember that it is not only their conservation we urgently need to cover. It is also our own indulgences.
How can you describe the threats existing to species, both large and small? Using the highly-threatened primates, we can perhaps see how they have contrived to exist until the current time. Then we can better understand just how we can prevent factors simply wiping them from the face of the earth, often through ignorance, lack of care, prejudice and of course the universal profit motive. Conservation begins in our minds, but demands much more than that.
What does that blue butterfly do when you are not watching. We still have to discover exactly how the Eurasian large blue exploits Myrmica ants, but many of its relatives are either cuckoos (eg. (Phengaris alcon), or outright predators like the AustralasianLiphyra brassolis larvae ,eating the whole brood of the green ants they live with. How did such diverse habits evolve? Well, start reading here.
