[Background] Both parasitic load and resource availability can impact individual fitness, yet little is known about the
interplay between these parameters in shaping body condition, a key determinant of fitness in wild mammals
inhabiting seasonal environments.
[Methods] Using partial least square regressions (PLSR), we explored how temporal variation in climatic conditions,
vegetation dynamics and sarcoptic mange (Sarcoptes scabiei) severity impacted body condition of 473 Iberian ibexes
(Capra pyrenaica) harvested between 1995 and 2008 in the highly seasonal Alpine ecosystem of Sierra Nevada Natural
Space (SNNS), southern Spain.
[Results] Bottom-up regulation was found to only occur in healthy ibexes; the condition of infected ibexes
was independent of primary productivity and snow cover. No link between ibex abundance and ibex body
condition could be established when only considering infected individuals.
[Conclusions] The pernicious effects of mange on Iberian ibexes overcome the benefits of favorable environmental
conditions. Even though the increase in primary production exerts a positive effect on the body condition of healthy
ibexes, the scabietic individuals do not derive any advantage from increased resource availability. Further applied
research coupled with continuous sanitary surveillance are needed to address remaining knowledge gaps associated
with the transmission dynamics and management of sarcoptic mange in free-living populations
