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.
The Olympics might be over, but that doesn’t mean that gymnastics have to take a backseat. For those in the Northern Hemisphere it is that time of year where the squirrels are 1) chonky and 2) scampering about to top up their cache for the winter – often making death defying leaps and bounds in the process. A cool research project set out to look at just how athletic squirrels are – and lets just say they could definitely make it to the national gymnastics team!
Acrobatic squirrels learn to leap and land on tree branches without falling
These gymnastic skills are important to help minimise what would be life (not career) ending injuries for squirrels as they navigate their way through the canopies. The cool part though? Its not just skill, there’s also some learning involved in making and surviving these acrobatic leaps. Squirrels learnt how to account for the ‘bendiness’ of branches when judging their leap – but also have the needed skills to correct should they have miscalculated before making the leap.

Milk, cheese and ice cream…if these words make your mouth water rather than induce a panicked search for the nearest bathroom, you’re one of humanities’ recently evolved lactose-tolerant specimens.

Fascination with nature drives a huge chunk of tourism worldwide. The plains of Africa, the Amazon Rainforest, the Swiss Alps and their associated species are huge economic drivers for their respective countries, and they (ideally) increase people’s appreciation of nature. There are plenty of great examples of ecotourism as a pathway for both education and conservation.
Yet when an industry is driven by money first, nature second, of course there are going to be manifold examples of businesses deprioritising the natural phenomena they are associated with, often to the direct detriment of that phenomena. Think the masses of pollution now found around Mt Everest, or the damage caused by avid snorkellers on the Great Barrier Reef. I’ve had my own experience with tourist companies deliberately spreading misinformation about the reef – more on that at this link.

Previously on this site I’ve summarised an article I wrote linking some concepts from behavioral ecology with evolutionary biology. Now I’m back to say a bit more about what behavioral ecology actually is. Being introduced to the field of behavioral ecology was what sparked me to actually consider a career in science. It’s a fascinating and beautiful field, and I hope I can show you why!

Why do animals behave the way they do? Behavioral ecology is a field of research trying to explain the ecological rationale of animal decision making. But quite often, it turns out the animals are doing the ‘wrong’ thing. Why don’t all animals make the same choice, when there clearly is a best option? Why do animals consistently do too little or too much of something?

In the latest edition of our ongoing look at how ecology has changed over the last half-century, 5 experts talk technology, modelling, and the study of humans. But we also cover some of the pitfalls of recent leaps forward, including the loss of appreciation for species physiology.
