It may be time to hit the road in pursuit of scientific research. Millions of animals are struck and killed by vehicles every year. These accidents have even pushed some species towards extinction. While roadkill is never pleasant, such loss of animal life could provide an opportunity to conduct scientific research more ethically.
Roadkill could be a “valuable source of animals for study that does not require and could even replace the use of live wildlife”, said a study published in the journal Biology Letters. Researchers identified approximately 117 different uses for roadkill across various scientific projects. “We found examples of successfully using roadkill to map species distributions, monitor disease and environmental pollution, study diets, track invasive species, supply museum collections and even discover species previously unknown to science,” said Dr Christa Beckmann of RMIT University in Melbourne, the lead author of the study.
A big advantage of using roadkill for research is that it is “highly ethical”, according to the study, and could be used as an alternative to invasive sampling methods. “If you want to take a genetic sample, you don’t need to trap live animals or handle them, both of which can cause stress,” said Beckmann.
In a car-centric society, roadkill is an unfortunate side-effect. Some species are even being “driven towards extinction because of traffic”, according to Scientific American. “Vehicles continue to be overlooked environmental forces that are likely to decimate more and more animal populations.” Despite this, said Beckmann, “using these losses wisely could help drive scientific discovery and conservation forward, rather than letting valuable information decompose by the roadside”. |
