News - How camera sensors works

For those of you who have not noticed that I am a geek...  this should clinch it for you. The combination of science and photography in an informative video! Awesome! The guys at Filmmaker IQ made this great video explaining how camera sensors work...  lots of science in it, but it is very well explained and easily digested. So I suggest you check them out, subscribe to their channel and all the rest of it too! :) Thanks, and enjoy!

News - Spotted in the news

A recent paper in PLoS ONE by Vidya Athreya et al., used an innovative method to examine Leopard populations in the Indian state of Karnataka. They searched local media sources for any mentioned leopard-human incidents and applied modelling methods to draw conclusions. Their data showed that "leopards occupied around 84,000 km2 or 47% of the State’s geographic area, outside designated national parks and wildlife sanctuaries".

The news is not getting any better, with the french government landing on the side of livestocks. [LPO reports]

News - Crowd Sourcing Science

A recent paper by Brewin et al. 2015 in PLOS looks at "the Potential of Surfers to Monitor Environmental Indicators in the Coastal Zone". In short, they demonstrated that by using the abundant surfer population in the south west United Kingdom (UK), they could generate ~40 million data points per year, overcoming the current inadequate sampling methods. This data would be invaluable for costal monitoring and management.
