The Gypsies problem in Europe
October 4, 2015 07:34 AM - Dan Allen, University of Salford, The Ecologist

Under new planning rules, Travellers and Gypsies must be able to prove they are actually traveling to qualify for limited planning benefits to create new sites. But for many, it's impossible to do that. Not only to remain in employment, or education - but precisely because there are so few sites, that they are unable to travel.

Living on an unauthorised campsite carries a heavy weight of suffering and disadvantage. Travellers contend daily with the risk of criminalisation and eviction, as well as limited access to basic services such as running water and sanitation.

Any attempt to subsume diverse groups under one label is going to be fraught with tension - and this is certainly true in terms of the word 'Traveller'.

Plants migrate to higher altitudes because of climate change
September 16, 2015 02:46 PM - Aarhus University

Although most of the world’s species diversity is found in tropical areas, there are very few studies that have examined whether tropical mountain species are affected by climate change to the same extent as temperate species. A new study has now determined that major changes have taken place during the last two centuries.

By comparing the migration of plant communities on the Chimborazo volcano in Ecuador with historical data from 1802, Aarhus University researchers found an average upslope shift of more than 500 metres. The entire vegetation boundary has moved upwards from 4,600 metres to almost 5,200 metres. The main explanation for this dramatic shift is climate change over the last 210 years.

New Sensor Tag Technology Could Link Animal Behavior and Conservation Science


For wild sockeye salmon, the trip upriver from the ocean to their spawning grounds is fraught with peril and hardship. But quantifying exactly how obstacles along the way, fluctuations in water temperature and other factors impact fish survival has long eluded researchers. New advances in biological sensor tags are now allowing scientists to precisely measure animals’ energetics, their interactions with humans, and their responses to rapidly changing environments.

In 2014, for example, Nicholas Burnett and colleagues used accelerometer tags to measure how salmon needed to swim in order to traverse a dam in the Seton-Anderson watershed of British Columbia, Canada and how likely they were to survive the remainder of their journey. They found that when salmon resort to strenuous anaerobic swimming, they were significantly more likely to die days or even hours later.
