Spatial structure and nest demography reveal the influence of competition, parasitism and habitat quality on slavemaking ants and their hosts
2010
Abstract Background Natural communities are structured by intra-guild competition, predation or parasitism and the abiotic environment. We studied the relative importance of these factors in two host-social parasite ecosystems in three ant communities in Europe (Bavaria) and North America (New York, West Virginia). We tested how these factors affect colony demography, life-history and the spatial pattern of colonies, using a large sample size of more than 1000 colonies. The strength of competition was measured by the distance to the nearest competitor. Distance to the closest social parasite colony was used as a measure of parasitism risk. Nest sites (i.e., sticks or acorns) are limited in …
Argumentativeness among Selected Finnish and American College Students
1991
Summary.-Compared on the Infante/Rancer Argumentativeness scale, 247 Finnish university students had a significantly higher mean score on argumentativeness as a trait than 155 American university students. No significant difference was noted on the desire to approach arguments, but the American students were significantly more inclined to avoid arguments than the Finnish students. Conceptualized by Infante and Rancer (1982) as a personality trait, argumentativeness contains tendencies to approach and to avoid arguments. Persons with approach tendencies will advocate issues on controversial positions and attack conflicting positions. Those with avoidance tendencies try to stay out of argumen…
