Researchers engineered a 3D-printed robotic rattlesnake to test how 38 zoo animals responded to rattling behavior. The study found that the rattling display functions as an effective deterrent, with species sharing natural geographic range with rattlesnakes exhibiting stronger fear responses.
Researchers found that as humpback whale populations recovered from whaling, the age structure shifted towards a more even distribution among older and younger males. Older males became increasingly successful at siring offspring compared to younger males, suggesting they need time to refine their singing and competitive tactics.
Research found that dogs and 16-month-old toddlers exhibited similar prosocial behaviour when searching for a hidden object, with over 75% of them indicating or retrieving the object. In contrast, companion cats rarely showed such behaviour, suggesting domestication may not be enough to produce human-like cooperation.
A new study published in Global Ecology and Conservation found that released animals, like Bengal slow lorises, are at risk of being attacked by territorial peers. Only two out of nine released animals survived, with the others dying due to fatal attacks.
