本文对巴拿马两个气候带--"季节湿润带"和"过湿润带"的森林爬行动物和两栖动物进行了定性和定量研究。“蜥蜴Gonatodes albogularis fuscus的分布和丰度似乎更多地受到环境结构配置的影响，而不是小气候条件。该树种的密度与鳞皮树种的密度密切相关。它也占据类似的几何配置（广泛的垂直表面裂缝）在非森林地区。相比之下，密度的蜥蜴，阿诺利斯limifrons，在不同的森林没有相关的结构特征，他们以前被证明是相关的密度。围栏样方表明，较低的森林层的两栖动物区系由两个非常丰富的物种与大量的稀有的。这些丰富的物种的密度与普通温带的。A. limifrons在过湿区的定义不如在季节性潮湿区的定义那么清晰，这可能是因为前者的降雨分布更均匀。季节性湿润区的物种比准湿润区少，这主要是由于青蛙数量的减少。
Qualitative and quantitative studies were made on reptiles and amphibians in forests of two climatic zones in Panama', des- ignated as the "Seasonally Humid Zone" and the "Perhumid Zone." Distribution and abundance of the lizard, Gonatodes albogularis fuscus, seemed to be influenced more by the structural configuration of the environment than by microclimatic conditions. Densities of this species were closely related to density of trees with scaly bark. It also occupies similar geometric configurations (broad vertical surfaces with crevices) in nonforested areas. By contrast, densities of the lizard, Anolis limifrons, in different forests did not correlate with density of structural features with which they had been previously shown to be associated. Fenced quadrats indicated that the herpetofauna of the lower forest strata consisted of one of two extremely abundant species with a larger number of rare ones. These abundant species had densities comparable to those of common temperate ones. The breeding season of A. limifrons is less sharply defined in the Perhumid Zone than in the Seasonally Humid one, probably because of the more uniform distribution of rainfall in the former. The Seasonally Humid Zone contains fewer species than the Per- humid one, largely due to a reduction in number of frogs.
