"Wolves Infected by Mind-Altering Parasite Exhibit Strange Behavior"

A 26-year study of wolves in Yellowstone National Park reveals that infection with the parasite Toxoplasma gondii significantly increases the likelihood of wolves becoming pack leaders and taking more risks. The parasite, which can only reproduce in felines but infects many warm-blooded animals, appears to alter wolf behavior, potentially affecting pack dynamics and ecosystem interactions. This underscores the importance of considering parasite infections in wildlife research.
