Abstract

Agricultural intensification has increasingly destroyed natural habitats, resulting in species declines. Insights into the effects of landscape structure on species’ diversity and distribution are needed to effectively conserve biodiversity in agricultural landscapes. The influence of land use practices on amphibian species diversity was investigated in areas of intensive and subsistence agriculture in Namulonge (Uganda, East Africa) using visual encounter surveys while environmental parameters were also recorded. A total of 19 amphibian species were recorded. Species richness varied minimally between intensive and subsistence agriculture plots. However, there was a significant variation in species’ abundance between the two land use areas and the species diversity was reduced in the intensive-agriculture area. The relationship between habitat characteristics and species distribution was statistically significant: in areas with relatively intact natural vegetation cover more species occurred. Such pockets of vegetation provide microhabitat conditions suitable for foraging, breeding and cover. Therefore, the abovementioned observation suggests that there is value at the landscape level to preserve natural/seminatural pockets of vegetation to enhance biodiversity in any agricultural environment.

乌干达集约化农业与自给农业地区两栖动物多样性比较

农业集约化日益破坏自然栖息地，导致物种减少。研究景观结构对物种多样性和分布的影响是有效保护农业景观生物多样性的必要条件。在纳穆隆格(东非乌干达)集约化和自给农业地区，采用目视接触调查方法调查了土地利用方式对两栖动物物种多样性的影响，同时记录了环境参数。共记录两栖动物19种。物种丰富度在集约化和自给农业样地之间差异最小。但两种土地利用区物种丰富度差异显著，集约化农区物种多样性降低。生境特征与物种分布的关系具有统计学意义:在自然植被覆盖相对完整的地区，物种分布较多。这样的植被口袋提供了适合觅食、繁殖和覆盖的微生境条件。因此，上述观察结果表明，在景观层面上，保护自然/半自然的植被，以增强任何农业环境中的生物多样性都是有价值的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
