The researchers apply this principle to the gray wolf case in the northern Rocky Mountains.
African ranchers may need to rethink their approach to managing savanna rangelands, as a new study suggests that coexisting with wildlife can enhance cattle growth. Grazing by wild animals like zebras can actually improve the quality of grass for cattle during the wet season when grass becomes rank and unproductive.
Research found that wolves and elk avoided high-quality habitat near trails with human activity above two persons per hour, suggesting a refuge zone for elk from predators. Thresholds of human activity on trails lead to wildlife disturbance and ecological change, according to the study.
A new study reveals that wild animals like zebras can sometimes enhance cattle growth and production, especially during times of plenty. Grazing by zebras reduced weight gain for cattle in the dry season but increased it in the wet season due to improved grass quality.

Researchers have observed a rise in 'naked' penguin chicks with feather-loss disorder in both Argentina and South Africa, causing concern among scientists. The disorder is thought to be related to increased energy spent on thermoregulation, potentially linked to pathogens, thyroid disorders, or nutrient imbalances.
Two new studies by UC Davis researchers found a direct link between lead ammunition and lead poisoning in scavenger birds like eagles and turkey vultures. The studies suggest that hunting with lead ammunition can have devastating effects on these bird species, causing inability to fly, starvation, anemia, blindness, seizures and death.
A recent European study found that dormice in certain habitats live longer due to fewer predators and successful avoidance methods. The animals' ability to accumulate fat reserves helps them survive harsh winters.
A new study found that human metapneumovirus and bacterial pneumonia contributed to the deaths of mountain gorillas in Virunga National Park. The virus was closely related to strains circulating in South Africa, suggesting that tourists may have carried it into the parks.
