Abstract

Establishing clear, rationales for conservation actions is critical to optimizing the chances of rescuing threatened species worldwide. We propose a simple habitat suitability index, a trade-off between occupancy probability and extinction risk, to guide conservation actions for the blond capuchin monkey (Sapajus flavius), whose distribution spans the contrasting but adjacent Atlantic Forest and Caatinga phytogeographic domains of northeastern Brazil. Our objective was to create a map to spatially coordinated management options considering both domains under two divergent but plausible scenarios assuming contrasting conservation outcomes: (1) active conservation efforts, in which government agencies/communities agree to invest and participate in conservation actions; and (2) no intervention and no additional effort. Based on the habitat suitability index, sites were classified into three types: A (protected and suitable, n = 3); B (suitable but under high extinction risk, n = 9); and C (unsuitable and highly defaunated, n = 75). Our results show that under Scenario 1 it would be possible to fund an active taskforce to improve forest quality in habitat remnant types B and C while supporting monitoring and protection of type-A sites. However, little can be done under Scenario 2 without successful educational programs to raise awareness and change the perception of local stakeholders. This study introduces a spatial index to prioritise conservation actions at key sites, providing a practical approach to effective resource management in a changing environment. Our protocol may be useful in guiding conservation action in the face of resource constraints and rapid environmental and climatic change in increasingly threatened biodiversity hotspots.

指导灵长类易位选址的简单适宜性指数:以巴西东北部为例。
为保护行动建立明确的基本原则,对于优化世界范围内拯救濒危物种的机会至关重要。本文提出了一个简单的栖息地适宜性指数,即占有概率和灭绝风险之间的权衡,以指导巴西东北部大西洋森林和Caatinga植物地理域的金发卷尾猴(Sapajus flavius)的保护行动。我们的目标是在两种不同但似乎可行的情况下创建一个空间协调管理方案的地图,考虑两个领域,假设不同的保护结果:(1)积极的保护努力,政府机构/社区同意投资和参与保护行动;(2)无需干预,无需额外的努力。根据生境适宜性指数,将样地分为三类:A(保护适宜,n = 3);B(适宜但濒危程度高,n = 9);C(不合适,高度默认,n = 75)。结果表明,在情景1下,有可能在支持监测和保护a类遗址的同时,资助一个积极的工作组来改善B和C类栖息地遗迹的森林质量。然而,如果没有成功的教育计划来提高认识并改变当地利益相关者的看法,那么在情景2下就很难有所作为。本研究引入了一个空间指数来优先考虑关键地点的保护行动,为在不断变化的环境中进行有效的资源管理提供了一种实用的方法。在面临日益严重威胁的生物多样性热点地区,面对资源限制和快速的环境和气候变化,我们的议定书可能有助于指导保护行动。

期刊介绍: Primates is an international journal of primatology whose aim is to provide a forum for the elucidation of all aspects of primates. The oldest primatological journal, Primates publishes original papers that advance the scientific study of primates, and its scope embraces work in diverse fields covering biological bases of behavior, socio-ecology, learning and cognition, social processes, systematics, evolution, and medicine. Contributions relevant to conservation of natural populations and welfare of captive primates are welcome. Studies focusing on nonprimate species may be considered if their relevance to primatology is clear. Original Articles as well as Review Articles, News and Perspectives, and Book Reviews are included. All manuscripts received are initially screened for suitability by members of the Editorial Board, taking into account style and ethical issues, leading to a swift decision about whether to send the manuscript for external review.
