OSORNO, Chile (April 4, 2025) — Research conducted in southern Chile has analyzed the potential for disease transmission between invasive and native mammal species, raising concerns about ecological and public health risks.
Doctoral Research Focuses on Biological Invasions
Alexis Santibáñez Barría, academic director at Santo Tomás university (UST) in Osorno, recently earned a doctorate in biodiversity Conservation and Management after defending his thesis on the subject. His research investigated the transmission of diseases between invasive species and native wildlife, with implications for human health.
Study Examines Disease Spread Among Mammals
Santibáñez’s research focused on characterizing interactions between several mammal species to estimate the probability of disease contagion. The study included domestic dogs, invasive mink, native otters, and various rodent populations.
“Indirect interactions between these mammals were characterized,estimating the probability of contagion of four diseases: distemper,canine parvovirus,leptospirosis and yersiniosis,” Santibáñez said. He noted that distemper and canine parvovirus are typically found in dogs, while leptospirosis and yersiniosis affect rodents and can be transmitted to humans, posing a public health risk.
Researcher Calls for Applied Science to Solve Socio-Ecological Problems
Santibáñez emphasized the importance of researchers contributing to applied science in Chile, aiming to provide concrete solutions to socio-ecological problems and promote innovation for enduring development.
He advocated for national-level action through research funding from the National Research and Development Agency (ANID), which manages science, technology, and innovation programs under the Ministry of Science, Technology, Knowledge and Innovation.
Regional Governments Urged to Support Research Initiatives
Santibáñez also highlighted the role of regional governments in supporting research through the Innovation Fund for Regional Competitiveness (FIC-R),part of the National Regional Development Fund (FNDR). This fund aims to promote applied research in productive sectors, improving development opportunities and quality of life for the population.
He stressed the need for efficient public-private alliances to improve the quality of life for local communities, focusing on key areas such as peasant family agriculture, ecotourism, renewable energies, food security, aquaculture, climate change, and biodiversity.
Recommendations for Vision Control
Based on his doctoral thesis, Santibáñez proposed measures to intensify biological control efforts targeting invasive mink populations:
- Reinforce mink capture programs, particularly at the northern edge of their distribution, to limit their spread and improve disease diagnosis.
- Implement mandatory vaccination programs for rural dogs and control measures on mink entering private properties. Rodent control measures should be even stricter due to their role as disease hosts.
- Share information in open-access repositories to promote collaboration between universities, state agencies, and peasant family agriculture, aiming to reduce economic losses caused by biological invasions. Losses caused by mink in Chile could reach $500 million over 20 years, according to estimates.
