Fungus from California suspected of killing cypress trees worldwide

Fungus from California suspected of killing cypress trees worldwide

Posted Sat, 03 Sep 2011 13:11:00 GMT by Gracie Valena

Genetic analysis has determined a fungus that has been causing cypress canker disease and killing trees in six out of the world's seven continents originated from California. The fungus, Seiridium cardinale, enters a tree through cracks in the bark. Once inside, it releases toxins that interfere with the flow of water, sap and nutrients, making the tree sick and eventually killing it.

An extraordinary jumping, land-living fish could tell us a lot about how life first moved from sea to land according to the first detailed study of its life. The study, study published in the journal Ethology and led by Dr Terry Ord, of the UNSW Evolution and Ecology Research Centre is the first detailed examination of the extraordinary life of the Pacific leaping blenny.

RSPB website follows one of Britain's favourite birds on a perilous journey. Ospreys migrate to Africa for the winter, returning in the spring, and this hazardous journey can now be analysed as some birds have been fitted with satellite tracking by the Royal Society for the Protection of Birds (RSPB).

An asian beetle is finding a welcoming new home in the iconic forests of the American north east causing damage that could threaten the area's $1 billion tourist industry say researchers. The Asian longhorned beetle is the alien species in question and scientists fear it could spread from tree-lined city streets to the north east's beautiful maple forests.

A three-week expedition through some of the unexplored remnants of Amazonian rainforest, in Brazil's Mato Grosso state, has uncovered a wealth of nature - including a brand new species of monkey. The new member to the titi monkey family was discovered alongside new species of fish and plants, all in a part of the Amazon where most of Brazil's deforestation is happening.

Recently the media has been full of stories about 'killer sharks' and, according to a leading expert, it could be a change in human behaviour that is creating the conditions for such incidents. Richard Pierce, a UK-based shark conservationist and a writer and broadcaster, believes that because we spend more time in the water, the risk of confrontation between man and shark is increasing.

Researchers have linked declining wild salmon populations with infestations of parasitic sea lice emanating from intensive salmon aquaculture in the Broughton Archipelago in Canada. After a number of contradictory reports, scientists have correlated sea lice outbreaks with the depletion of wild salmon populations of pink and coho salmon.

Not all MCS-labeled fish turn out to be true to their sticker, according to a new study on the make-up of the Chilean sea bass, commonly found in US grocery stores. Many of the fish labeled as sustainably-sourced in fact comes from different South American fisheries, or even from oceans on the other side the world, say the authors of the work published in Current Biology.

A new study in Science shows that the natural world moving three times faster to the poles, away from the tropics, than expected. Climate change is blamed, say the researchers, and not all species can keep up at that rate.

In a new series of features, the Earth Times asks two leading experts to give their views on some of the hottest green topics of the 21st century. This week, we ask: Are zoos a force for good, or just an out-dated mode of animal cruelty? Tackling the issue head-on are Liz Tyson and Rosalind Smith.

Previously believed to be mere decorative carpets, soft corals play a vital role in reef ecosystems, scientists find. Previously, scientists believed soft corals simply disintegrated, their sclerites scattering to the sea floor.

A local community's dedication led marine reserve Cabo Pulmo to the most dramatic fish recovery scientists have ever seen. Ten years ago, the marine reserve Cabo Pulmo in the Gulf of California struggled for survival but the depleted ecosystem has become a biodiversity hotspot in less than 10 years.

Photographic evidence has emerged that suggest the Japanese earthquake and subsequent Tohoku Tsunami caused 50 square miles of ice to break off Antarctica. Images from the European Space Agency show that icebergs, some larger than Manhattan island, broke away from Antarctica just a few days after the quake.

Could flirting make males age faster?

Could flirting make males age faster?

Posted Fri, 05 Aug 2011 12:41:00 GMT by Kieran Ball

Scientists looking at the sex lives of birds have concluded that attracting members of the opposite sex through mating rituals could cause males to age faster. The scientists put forward the theory that because the birds lived in a habitat with many predators, they evolved a mechanism by which they put more energy into mating in early life - a form of biological trade-off that resulted in premature aging.

A novel way to avoid the tragedy of boats and right whales colliding is being suggested by new research into the feeding habits of the North Atlantic right whales - by tracking their prey. These endangered whales may number as few as four hundred, and inadvertent ship strikes account for worryingly high number of deaths each year.
