研究：一些寄生虫群体锐减或影响生物多样性

Core Insights - An international research team reported a significant decline in the population of the endangered Kakapo parrot, leading to the disappearance of its unique parasites, which may have broader implications for biodiversity [1][2] - The study analyzed ancient and modern fecal samples to create a timeline of changes in the Kakapo's intestinal parasites, revealing a drastic reduction in parasite diversity due to population decline and human intervention [1] Summary by Sections - Research Findings - The Kakapo once hosted 16 types of parasites before the 1990s, but currently only 3 types can be detected, indicating that some parasites may have gone extinct [1] - The loss of these parasites could disrupt ecological balance, as they play crucial roles in maintaining biodiversity, regulating species competition, and stabilizing food chains [1] - Broader Implications - The researchers highlighted that many animal species worldwide are facing population declines, and the silent disappearance of unique parasites may have significant effects on host health and ecosystem stability [2]
