Ungulates and trains – factors influencing flight responses and detectability (2022) Bhardwaj et al., Journal of Environmental Management, https://doi.org/10.1016/j.jenvman.2022.114992
Trains are one of the most climate-friendly ways to cross long-distances. Whether it’s people heading off on holiday or transporting food, clothing or other goods, it’s a (usually) cheap and low-emissions method of travel.
Yet train-animal collisions can be a massive problem for wildlife. Deer in Europe, bears in North America, and elephants in India are three of the many, many groups of species that suffer mortalities every year when they’re hit by trains. The collisions aren’t exactly friendly to the trains either, with many drivers suffering from trauma and repairs often need to be made (granted, not as bad as being run over).
Understanding more about animal behaviour in the face of a train can help us figure out how to prevent these collisions. Today’s authors enlisted the help of Swedish train drivers in an attempt to understand how animals behave when confronted with an oncoming mass of metal.Read more
