Abstract
Understanding how the urbanization process affects the lives of animals that live in these environments is relevant to conservation and management. In fact, the urbanization process has a direct impact on animals and can influence their health state. Thus, our objective was to investigate the immunological response of birds to the urbanization process. We recorded the H/L ratio of 723 birds of 10 species captured in Brasília (a large city in central Brazil), as a measure of chronic stress in birds. The H/L ratio was positively associated with the intensity of urbanization and negatively associated with body condition. However, body condition was not associated with intensity of urbanization. We confirmed our hypothesis that birds living in areas with greater urban intensity are more stressed. In addition, we demonstrated that the H/L ratio is negatively associated with body condition, and that this variable should be considered in studies that aim to assess the health of animals. These findings are relevant because they confirm that the urbanization process, along with all its environmental changes (increased artificial light, increased noise, suppression of vegetation, increased built-up areas, etc.), has a negative direct impact on wild populations, which have to deal with major urban changes.
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.
