Deer Learn To Ignore Deterrents: Human shouts scare best; habituation soon blunts effect

Research indicates that loud human noises and bright lights were effective in driving deer and elk away from crops, while predator sounds and dog barks didn’t have the same effect. Over a period of six weeks, these animals became accustomed to the deterrents, especially those near human activity. Researchers recommend diversifying stimuli and introducing consequences to keep these animals from adapting.

In the 1850s, pigs brought to Santa Cruz Island became feral

Feral pigs were eradicated from Santa Cruz Island, facilitating a resurgence in fox populations. With bald eagles no longer in the area, golden eagles preyed on the island's foxes. In response, conservationists captured the golden eagles and reintroduced the native bald eagles. A captive breeding initiative safeguarded the remaining island foxes from predators, resulting in a successful revival of the island's native wildlife and ecosystem.

In 2019, scientists shook earthworms and found waves oscillating at half the driving frequency

Scientists observed earthworms developing body waves at half driving frequency. Their flexible, water-filled bodies and elastic skin supported these unusual oscillations. This phenomenon resembled waves found in vibrating liquid drops and phantom models. Researchers believe this could help probe biological processes like nerve impulse propagation. The findings suggest nonlinear wave excitation has potential beyond earthworm studies.
