The skeletal elements of mountain gazelle (Gazella gazella) have proven difficult to sex with statistical confidence due to wide overlap in the body size of the two sexes. We studied a sample of 53 modern mountain gazelle skeletons to determine which character traits and metric measurements best predict sex. The success of the character traits was determined using blind tests while the metrics were examined using discriminant function analysis. The most useful elements include the previously identified horn core, pubis and atlas, but also some new bone portions that preserve well in the archaeological record (e.g., distal tibia, distal metacarpal and metatarsal, and second phalanx). Surprisingly, two elements commonly used in sexing analyses (distal humerus and astragalus) were not among the most effective elements. Although cutting points and discriminant functions for sexing gazelle bone portions are presented here, they do not account for potential body size change and thus are not suited for direct application to archaeological assemblages. Instead, we provide guidelines for application to archaeological gazelle assemblages, most importantly a regression analysis that considers the sex ratios obtained from multiple measurements to predict the sex ratio of archaeological gazelle populations.  相似文献

This introduction to the special issues starts with a general overview of the literature. The relationship between climate, climate change, and conflict has been empirically tested in a wide variety of studies, but the literature has yet to converge on a commonly accepted set of results. This is mainly due to poor conceptualization of research designs and empirical measurements. Data are often collected at different temporal, geographic, and social scales. In addition, “climate” and “conflict” are rather elusive concepts and scholars have utilized different measures of each. The choice of measures and empirical tests is not a trivial one, but reflects different theoretical frameworks for understanding environmental influences on conflict. Therefore, results from different analyses are often not commensurable with one another and readers should be wary of broad, sweeping characterizations of the literature. The individual contributions to the special issue are also discussed. Articles herein focus on different geographic regions, temporal periods, and levels of conflict, adding additional layers of complexity to our understanding of the climate/conflict nexus.  相似文献
