However, most studies aggregation have been conducted the laboratory. In this study, I investigated tendency six species snakes to rocks field southern Ontario, Canada. Most were by themselves, but found single- and mixed-species aggregations up four Although all involved aggregations, did not find possible combinations species; no more than two species. Goodness-of-fit tests suggested that pattern sizes was described geometric distribution, implying nonrandom toward aggregation. Nonetheless, because data pooled over time, random occurrence cannot be rule...
