Abstract

The lizard genus Uracentron, family Tropiduridae, is composed of the species Uracentron flaviceps (Guichenot, 1855) and Uracentron azureum (Linnaeus, 1758). Both species have arboreal habits and are endemic to the Amazon. Here we report a new geographical record of Uracentron azureum guentheri from western Pará State, Brazil, and the first record for the species in the Tapajós/Xingú interfluve. Two specimens were recorded in a fragment of secondary forest on the right bank of the Curuá-Una River, downstream of the Curuá-Una Hydroelectric Power Plant dam, in Santarém, Pará, Brazil. The specimen has colour and morphological features that fit guentheri subspecies. With this new record, Uracentron azureum guentheri is now known in 15 locations in Peru (Loreto department) and Brazil (Amazonas, Mato Grosso, Pará, and Rondônia States), expanding its distribution approximately 209 km southeast of the nearest previously known location (Oriximiná Municipality). Recording and reporting such new geographical records is essential since it allows distribution gaps to be filled and is important for understanding biodiversity patterns, speciation processes and phenotypic variations, as well as contributing to conservation planning. The identification of priority areas for protection can be improved with such data, helping to reduce environmental impacts and preserve local biodiversity.

巴西亚马逊河流域Tapajós/Xingú间接区绿刺尾鬣蜥的首次记录(鳞目:棘尾鬣蜥科)
棘蜥属,棘蜥科,由黄棘蜥属(Guichenot, 1855年)和蓝棘蜥属(Linnaeus, 1758年)组成。这两个物种都有树栖习性,是亚马逊特有的。本文报道了在巴西par州西部发现的一种新的azureum guentheri的地理记录,以及该物种在Tapajós/Xingú区间的首次记录。在巴西帕尔的santarsamim, Curuá-Una水电站大坝下游的Curuá-Una河右岸的一片次生林中记录了两个标本。标本的颜色和形态特征符合guentheri亚种。有了这一新的记录,现在在秘鲁(洛雷托省)和巴西(亚马逊州、马托格罗索州、帕尔州和Rondônia州)的15个地点已知了azureum guentheri,将其分布范围扩大到最近的已知地点(oriximin市)东南约209公里处。记录和报告这种新的地理记录是必不可少的,因为它可以填补分布空白,对了解生物多样性模式、物种形成过程和表型变化以及有助于保护规划非常重要。利用这些数据可以改进优先保护领域的确定,从而有助于减少对环境的影响和保护当地的生物多样性。

期刊介绍: Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere. Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region. Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
