| long term study of ixodid ticks feeding on red deer (cervus elaphus) in a meso-mediterranean climate. | red deer (cervus elaphus l.) are very valuable in trophy-hunting but also contribute to the preservation of natural areas. they are affected by many parasites and pathogens, including hard ticks that are not only important parasites themselves but can also act as vectors and/or reservoirs of pathogens. tick phenology is complex insofar as population dynamics depend on environmental conditions, vegetation, host availability and their own intrinsic characteristic. ticks were collected monthly from ... | 2016 | 26715543 |
