Re-emergence of Salmon in The Thames ‘Not From Restocking’ Say Exeter Academics

*The recent returns of Atlantic salmon in the Thames are more likely to be a result of fish straying from nearby rivers rather than a consequence of expensive restocking efforts, according to new research by the University of Exeter.*

A team of University of Exeter bio-scientists, in collaboration with the Environment Agency, Westcountry Rivers Trust and Oviedo University, Spain, have been collecting genetic data from returning fish, which suggests that habitat restoration was more effective than re-introductions. The findings will be published in the journal ‘Biological Conservation’.

Lessons from the study could be applied to other rivers across the UK according to the co-author of the paper Dr Jamie Stevens, Associate Professor of Molecular Systematics at the University of Exeter. Dr Stevens says: “Traditionally, people – such as river owners and anglers – have wanted big fish swimming up their rivers. The easiest way to ensure this quickly has been to restock those rivers with exogenous fish (from outside the river system).” (more…)

A University of Exeter archaeologist’s research has uncovered the largest Roman settlement ever found in Devon. The discovery could force us to rewrite the history of the Romans in Britain.

The discovery of a large Roman Settlement in Devon was the result of a chance metal detecting coin find. Danielle Wootton, the Finds Liaison Officer for the Portable Antiquities Scheme (PAS) and archaeologist at the University of Exeter was called on to investigate further. (more…)

*A University of Exeter academic, who is an expert on Islam, has contributed to the new television series ‘The Life of Muhammad’ currently being broadcast on BBC Two. The three-part documentary, presented by journalist Rageh Omaar, charts the story of the Prophet who, in little more than 20 years, changed the world forever.*

Professor Sajjad Rizvi, University of Exeter’s Associate Professor of Islamic Intellectual History at the Institute of Arab and Islamic Studies, provided expert advice to the BBC team. He also appears in the series. (more…)

Decline in Species Shows Climate Change Warnings Not Exaggerated

One in 10 species could face extinction by the year 2100 if current climate change impacts continue.

This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines.

Published in leading journal Proceedings of the National Academy of Sciences, the study uses the well-established IUCN Red List for linking population declines to extinction risk. The research examines nearly 200 predictions of the future effects of climate change from studies conducted around the world, as well as 130 reports of changes which have already occurred. (more…)

Research Reveals New Secret Weapon For Le Tour

Winning margins in the Tour de France can be tight. In 2010 just 39 seconds separated the top two after more than 90 hours in the saddle. When every second counts, riders do all they can to gain competitive advantage, from aerodynamic carbon fibre bikes to the latest sports nutrition.

Now there could be a new, completely legal and rather surprising weapon for riders aiming to shave vital seconds off their time – beetroot juice. (more…)

*A University of Exeter biologist has discovered a ‘lost’ species of bat breeding on the Isles of Scilly.*

*A pregnant female brown long-eared bat is the first of its species to be found on the islands for at least 40 years.*

It was discovered by Dr Fiona Mathews, Senior Lecturer at the University of Exeter, a postgraduate student and a team from the Wiltshire Bat Group.

The Scilly Isles Bat Group called in Dr Mathews and her team to help them find out more about bats on the islands. The researchers set up a radiotracking study, with funding from the Isles of Scilly Area of Outstanding Natural Beauty, to monitor the islands’ bat activity. (more…)

Research by experts at the University of Exeter has led to calls to create an international marine park to protect endangered sea turtles.

Scientists from the university’s Centre for Ecology and Conservation, based at its Cornwall Campus, worked with an international team to carry out satellite tracking of olive ridley sea turtles off the coast of Central Africa for the study. (more…)
