摘要

.小型啮齿动物在繁殖季节依靠资源收集来支持其繁殖产量和后代生存。由于农田可能提供互补的食物来源，我们评估了玉米地对黑渐殖吸虫（Olfers，1818）丰度和繁殖的影响。我们发现，在玉米地森林边缘，繁殖雌性和雄性的丰度、比例以及幼鱼的数量都较高，没有季节性，这与该物种的季节性繁殖模式不同。因此，我们的研究结果支持了玉米地有利于黑胡椒的丰富和繁殖成功的假设。

Cornfield effects on breeding and abundance of Oligoryzomys nigripes (Rodentia: Sigmodontinae)

. Small rodents rely on resource gathering during the breeding season to support their reproductive output and offspring survival. Since croplands may provide complementary food sources, we evaluated the influence of the presence of cornfield on the forest edge in Oligoryzomys nigripes (Olfers, 1818) abundance and breeding. We found that abundance, proportion of reproductive females and males, as well as the number of juveniles were higher in the cornfield-forest edges, with no seasonality, a pattern divergent from the seasonal reproduction described for the species. Therefore, our results supported the hypothesis of cornfields benefiting O. nigripes abundance and breeding success.
