Concern about emerging diseases has risen in recent years, and multihost situations have become increasingly relevant for wildlife management and conservation. We present data on Asturias, northern Spain, where 80 mangy red deer (Cervus elaphus) have been found since the beginning of the epizootic in chamois (Rupicapra pyrenaica parva) in 1993. We combine field and necropsy data with the results of a serosurvey using an in-house ELISA test to evaluate if deer mange due to Sarcoptes scabiei is an emerging disease in this area. The mean number of deer mange cases per year was 5, with a maximum of 16. No significant relationship was detected between monthly temperatures, rainfall or number of days with snow cover and the annual number of sarcoptic mange cases in red deer. Only 4 mangy red deer (5%) were detected outside the limits of scabietic chamois distribution during the same year, and all were less than 2500 m away from that limit. The longest distance reported between two consecutive mangy deer locations was 18 km. Mange cases were significantly more frequent in stags than in hinds and in adults than in juvenile deer. The time of the first mange detection in chamois in each sector, year with minimum number of chamois recorded, year with maximum chamois population decline rate and chamois density offered no significant correlation with red deer mange cases appearance moment and frequency. In the mange affected area, ELISA testing of 327 blood samples from hunter-harvested deer without obvious mange-compatible lesions revealed only 4 seropositive animals. All 83 sera from hunting preserves without clinical cases yielded negative ELISA results. According to these epidemiological data mange does not seem to threaten red deer populations in Asturias. However, continued monitoring of deer health and ELISA testing for sarcoptic mange is advisable. #

1. Integrating environmental concerns into sectoral policies is a priority for sustainable development. Despite environmental policy integration being established in Europe in 1998, major weaknesses still limit its effectiveness, such as poor coordination at national and subnational levels.2. We use the integration of scavenger conservation into sanitary European regulations to illustrate how the adoption of different criteria when implementing the same legislation affects the effectiveness of the environmental policy integration process. We focus on the implementation across Spanish autonomous regions of Regulation EU 142/2011 allowing dead livestock to be left in situ for feeding scavengers. Using Asturias (NW Spain) as a case study, we provide spatially explicit estimates of two key factors guiding the implementation of the legislation, the estimates of scavenger feeding requirements, and the area designated as scavenger feeding zones, based on different criteria used across Spanish regions.3. We detected a remarkable variation in both scavenger feeding requirements (up to 452%; ranging from 108 to 596 t/year) and scavenger feeding zones (up to 72% in size) depending on the implementation criteria used. 4. The concentration of scavenger feeding requirements per km 2 within scavenger feeding zones (i.e., carrion demand) varied up to 167%. Similarly, the concentration of carrion supply from livestock within scavenger feeding zones (i.e., carrion availability) changed up to 33%. Policy implications.Our results support the need for systematic evaluations to choose the best criteria for implementing sanitary regulations concerning scavenger conservation. Interregional coordination in implementing the agreed criteria emerges as a relevant issue to improve the effectiveness of environmental policy integration for transboundary conservation of European scavengers.
