Bar-headed Geese Give Insight Into Low Oxygen Tolerance
2014-04-08 14:58:41

University of Exeter A new study into how the world's highest flying bird, the bar-headed goose, is able to survive at extreme altitudes may have future implications for low oxygen medical conditions in humans. An international team of scientists recently tracked the bar-headed goose while it migrated across the Himalayas. Now they have shown how these birds are able to tolerate running at top speed while breathing only 7% oxygen. Exercising at high altitude is a massive challenge...

Pioneering new research from the University of Exeter could have a major impact on climate and environmental science by drastically transforming the perceived reliability of key observations of precipitation, which includes rain, sleet and snow. The ground breaking study examines the effect that increased aerosol concentrations in the atmosphere, emitted as a result of burning fossil fuels, had on regional temperature and precipitation levels. Scientists from Exeter's Mathematics...

Global Warming Could Increase Methane Emissions From Freshwater Ecosystems
2014-03-19 17:22:42

University of Exeter New research led by the University of Exeter suggests that rising global temperatures will increase the quantity of the key greenhouse gas methane emitted from freshwater ecosystems to the Earth's atmosphere – which could in turn lead to further warming. The collaborative study, led by Dr Gabriel Yvon-Durocher from the University of Exeter, collated data from hundreds of laboratory experiments and field surveys to demonstrate that the speed at which methane fluxes...

New Study Sheds Light On Animal Social Behavior
2014-03-06 15:04:31

University of Exeter A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations. Understanding the way in which social behaviors such as altruism – when animals benefit others at their own expense – develop is a long-standing problem that has generated thousands of articles and heated debates. Dr Florence Débarre of Biosciences at the University of Exeter led a study,...

Legally Caught Marine Turtles Tops 42,000 Each Year
2014-02-21 08:12:57

University of Exeter A new study has found that 42 countries or territories around the world permit the harvest of marine turtles – and estimates that more than 42,000 turtles are caught each year by these fisheries. The research, carried out by Blue Ventures Conservation and staff at the University of Exeter's Centre for Ecology and Conservation, is the first to comprehensively review the number of turtles currently taken within the law and assess how this compares to other global...

Hidden Crop Pest Threatens Poorer Nations
2014-02-11 15:34:01

University of Exeter The abundance of crop pests in developing countries may be greatly underestimated, posing a significant threat to some of the world's most important food producing nations, according to research led by the University of Exeter. Data on the known distributions of almost 2,000 crop-destroying organisms in 195 countries were analyzed in the first global assessment of the factors determining the distribution of crop pests. Dr Dan Bebber and Professor Sarah Gurr, of...

The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed. The research shows that a one degree rise in tropical temperature leads to around two billion extra tonnes of carbon being released per year into the atmosphere from tropical ecosystems, compared with the same tropical warming in the 1960s and 1970s. Professor Pierre Friedlingstein and Professor Peter Cox, from the University of Exeter, collaborated with...

New research by scientists at the University of Exeter has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide - a finding with potential links to the underlying causes of many cancers. The study, published today in Developmental Cell, describes a number of routes to the formation of a microtubule spindle – the tracks along which DNA moves when a cell divides in order to make two genetically identical cells. In order to understand the...

Mongooses Synchronize Births To Escape Infanticide
2013-12-24 07:28:41

University of Exeter Some mammals may have evolved to synchronize births as a way of evading the threat of infanticide, according to a study led by the University of Exeter. To ensure groups remain productive, some social animals 'police' selfish reproduction by subordinate animals by killing any offspring they produce. For example, in honeybees and other social insects some workers lay their own eggs, but these are identified and killed by the rest of the workforce. The new study...

High levels of tungsten in the body could double the risk of suffering a stroke, a new study published in the open access journal PLOS ONE has found. Using data from a large US health survey, the study has shown that high concentrations of tungsten – as measured in urine samples – is strongly linked with an increase in the occurrence of stroke, roughly equal to a doubling of the odds of experiencing the condition. Conducted by a team from the University of Exeter, the study...
