The use of remotely operated rovers to study penguins and seals in their natural habitats is less invasive and stressful for the animals, according to a new study. The findings, published in Nature Methods, also suggest that the rover's lower impact on animal behavior results in the collection of more accurate scientific data.
"Approaching animals with a rover can reduce impact, as measured by heart rates and behavior of king penguins, thus allowing such animals to be considered as undisturbed," the authors write. "The relevance of this technology extends beyond terrestrial populations of seabirds or mammals, as rovers could be adapted for use in aquatic or aerial environments."
