Abstract

The pied tamarin (Saguinus bicolor), a species that is emblematic of the Manaus region of Brazil, is threatened by the growth of the city and its peri-urban area. Our study aims to identify priority areas for biodiversity conservation in and around Manaus, the largest city in the Brazilian Amazon and home to over 2 million people. The geographic range of the pied tamarin, a critically endangered primate that is a symbol of conservation in the region, was used to define the boundaries of the study area. We treated the urban zone separately because of the greater barriers to conservation there and carried out systematic conservation planning for the rural zone. After defining biodiversity targets and variables and weighting for a cost surface (difficulty of protection), the map of priority areas was generated using MARXAN decision support software. Connectivity was strengthened using the LinkageMapper tool. Although protected areas already cover about 20% of the study area, most are in partially protected categories and are still losing vegetation. The results prioritize 56.1% of the pied tamarin distribution area, including urban and rural zones. The analysis of the current scenario causes concern because it shows that much of the effort to create protected areas is not as effective as it could be. The conservation of the pied tamarin, as well as other threatened primates, depends on a better understanding of the need to increase the amount of land set aside for their protection, improving monitoring, and restoring vegetation where possible.

一种濒临灭绝的亚马逊灵长类动物的保护：巴西马瑙斯斑毛猴（Saguinus bicolor）的优先区域

斑毛猴（Saguinus bicolor）是巴西马瑙斯地区的象征，它受到城市及其城郊地区发展的威胁。我们的研究旨在确定玛瑙斯及其周边地区生物多样性保护的优先区域，这是巴西亚马逊地区最大的城市，拥有200多万人口。斑毛猴是一种极度濒危的灵长类动物，是该地区保护的象征，它的地理范围被用来确定研究区域的边界。由于城市区域的保护障碍较大，我们对其进行了单独处理，并对农村区域进行了系统的保护规划。在定义生物多样性目标和变量并对成本面（保护难度）进行加权后，使用MARXAN决策支持软件生成优先区域图。使用LinkageMapper工具加强了连通性。虽然保护区已经覆盖了研究区域的20%左右，但大多数保护区属于部分保护类别，植被仍在减少。结果对斑毛猴分布区域进行了56.1%的优先排序，包括城市和农村地区。对当前情况的分析引起了关注，因为它表明，建立保护区的大部分努力并没有达到应有的效果。斑毛猴以及其他受威胁的灵长类动物的保护，取决于更好地了解需要增加用于保护它们的土地数量，改善监测，并在可能的情况下恢复植被。

期刊介绍： The Journal for Nature Conservation addresses concepts, methods and techniques for nature conservation. This international and interdisciplinary journal encourages collaboration between scientists and practitioners, including the integration of biodiversity issues with social and economic concepts. Therefore, conceptual, technical and methodological papers, as well as reviews, research papers, and short communications are welcomed from a wide range of disciplines, including theoretical ecology, landscape ecology, restoration ecology, ecological modelling, and others, provided that there is a clear connection and immediate relevance to nature conservation. Manuscripts without any immediate conservation context, such as inventories, distribution modelling, genetic studies, animal behaviour, plant physiology, will not be considered for this journal; though such data may be useful for conservationists and managers in the future, this is outside of the current scope of the journal.
