Abstract

The hypothetical link between a reduction in biodiversity and increased zoonotic diseases remains debatable. We tested this by utilising remote vegetation density and protected areas (PAs) as proxies for biodiversity and examined their relationship with triatomine richness and occupancy. Triatomine bugs serve as the primary vector for Trypanosoma cruzi, the causative agent of Chagas disease. Although no link was found between triatomine species richness and vegetation, triatomine occupancy was lower within PAs than outside. Consequently, our findings suggest that reduced biodiversity may lead to a greater occupancy of triatomines, which could increase the risk of Chagas disease.

生物多样性减少与高锥蝽占用率有关：恰加斯病的影响。

生物多样性减少与人畜共患疾病增加之间的假设联系仍有争议。我们利用偏远地区的植被密度和保护区（PAs）作为生物多样性的代表，并研究了它们与triatomine丰富度和占用的关系，以此来验证这一点。锥虫是恰加斯病的病原体克氏锥虫的主要媒介。虽然没有发现狐獴物种丰富度与植被之间的联系，但狐獴在保护区内的占用率低于保护区外。因此，我们的研究结果表明，生物多样性的减少可能导致锥蝽占据更多，这可能增加恰加斯病的风险。

期刊介绍： EcoHealth aims to advance research, practice, and knowledge integration at the interface of ecology and health by publishing high quality research and review articles that address and profile new ideas, developments, and programs. The journal’s scope encompasses research that integrates concepts and theory from many fields of scholarship (including ecological, social and health sciences, and the humanities) and draws upon multiple types of knowledge, including those of relevance to practice and policy. Papers address integrated ecology and health challenges arising in public health, human and veterinary medicine, conservation and ecosystem management, rural and urban development and planning, and other fields that address the social-ecological context of health. The journal is a central platform for fulfilling the mission of the EcoHealth Alliance to strive for sustainable health of people, domestic animals, wildlife, and ecosystems by promoting discovery, understanding, and transdisciplinarity. The journal invites substantial contributions in the following areas: One Health and Conservation Medicine o Integrated research on health of humans, wildlife, livestock and ecosystems o Research and policy in ecology, public health, and agricultural sustainability o Emerging infectious diseases affecting people, wildlife, domestic animals, and plants o Research and practice linking human and animal health and/or social-ecological systems o Anthropogenic environmental change and drivers of disease emergence in humans, wildlife, livestock and ecosystems o Health of humans and animals in relation to terrestrial, freshwater, and marine ecosystems Ecosystem Approaches to Health o Systems thinking and social-ecological systems in relation to health o Transdiiplinary approaches to health, ecosystems and society.
