Pollution constrains cold adaptation but not thermoregulation in dung beetles

Description

Assessment of the effect of ivermectin pesticide exposure on heat and cold tolerance, thermoregulation, and energetic status of the dung beetle Euoniticellus intermedius along an elevational gradient. Ivermectin influences on cold tolerance in individuals living at high elevations. Variations in thermoregulatory capacity were also detected across populations, but these were not affected by ivermectin. Heat tolerance was not influenced by elevation or ivermectin treatment.
