摘要：
The effects of weather on population fluctuation patterns of the South American muroid Calomys venustus were studied. Box-Jenkins data series analysis and anova were used to describe the relationship between climatic variables and population. No relation was found between maximum temperatures or precipitation and the C. venustus population. Temperatures below 4 degreesC appear to affect populations of the overwintered cohort after a time lag of 5 months. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
