The relationship of body weight and C.I.C points of horns to sex, age and biotope structure is discussed. With respect to biotope structure, two groups of areas are dealt with, namely section A, which encompasses mainly the altimontane and subalpine forest belt and areas above the upper timber line, and section B, which is covered mainly with montane and submontane forests. Section A is a biotope in which chamois has been present for a long time, while in section B it has spread during the recent decades. There are no significant differences between the two sections as to body weight, but C.I.C. points of horns of chamois living in section A are slightly higher. Also, section A is slightly less invaded by pulmonary parasites. On average, the proportion of chamois invaded by these parasites is as high as 77.9%. The proportion of invaded females is lower than that of males and similarly, the proportion of invaded subjects of older age is lower. The extent of the invasion of parasites is negatively correlated with body weight of a subject.
