摘要
A population of Mastomys natalensis was studied by the catch mark-release method from April 1983 to June 1984 in Morogoro, Tanzania. The observed cessation of reproduction during the dry season was accompanied by a reduction in growth. Average growth rates decreased during the dry season to the extent that the larger individuals suffered a considerable weight loss. The relationship between individual weight and reduction in growth suggests that resource limitation is sufficient to explain the break in reproduction.
