VALENZUELA-SANCHEZ, ANDRÉS  y  MEDINA-VOGEL, GONZALO. Importance of infectious disease for the conservation of Chilean threatened wildlife. Gayana (Concepc.) [online]. 2014, vol.78, n.1, pp.57-69. ISSN 0717-6538.

There is evidence that infectious diseases (IDs) can directly affect wildlife even causing catastrophic died-offs, which increase extinction risk. In this way, to achieve the biological conservation goal we should know the role of IDs on wild populations. The aim of this work was 1) to determine the contribution of IDs in Chilean wildlife declination, according to the IUCN Red List, 2) to evaluate the level of scientific evidence of this threat on wildlife from Chile, and 3) propose a risk level (for each threatened wildlife species) of become threatened by an ID with potential to leading population decline or extinction. In the country, 105 species are in some category of threat, of which 16.2% (N=17) have IDs as potential major threat. Despite this, no evidence is available into scientific literature about an ID producing population declines in Chile. We suggest that anuran species Telmatobius zapahuirensis and T. pefauri, and the canid Lycalopex fulvipes, need urgent efforts in epidemiological research; due in part by its restricted distribution and conservation status, which could increase risk of extinction driven by IDs. By the end, we suggest future directions to enhance the biological conservation in Chile.
