摘　　要：Amphibians require specific habitats for breeding and loss or degradation of such habitats can negatively affect reproductive success. Oviposition site selection within a habitat is also important as site quality is linked to larval survivorship and metamorphic success. We investigated oviposition site preferences of the stream-breeding frog Limnonectes blythii in Singapore through surveys and habitat measurements of breeding and non-breeding sites（N = 30 and 32, respectively）. The study species L. blythii is classified as Near Threatened（NT） in the IUCN red list and is associated with medium sized forest streams. L. blythii appeared to prefer streams with higher water p H and shallower water depths for oviposition. Our findings have implications in conservation management as it provides the baseline for habitat restoration for creation of new and for preserving existing breeding habitat of L. blythii.Amphibians require specific habitats for breeding and loss or degradation of such habitats can negatively affect reproductive success.
