Abstract

Marine protected areas (MPAs) are common conservation tools supporting the protection of threatened marine fishes, such as sharks. However, the creation of shark MPAs has been less common in the Greater Caribbean region despite a growing need and opportunity. In this study, we evaluated the occurrence of shark and reef fish biodiversity off Sint Maarten, Dutch Caribbean, with a particular emphasis on endangered shark presence within the Man of War Shoal Marine Protected Area (MPA). We utilized baited remote underwater video systems (BRUVs) to gather non-invasive data on the abundance and diversity of reef fish and shark species inside and outside the local MPA. Generalized linear models (GLMs) revealed no significant effect of protection status on the presence of the endangered Caribbean reef shark (Carcharhinus perezi). However, we found a significant influence of depth on shark occurrence, as well as an effect of habitat type on shark and reef fish biodiversity, with reef habitats showing the greatest significance. These results suggest that the effect of small coastal MPAs on bolstering local endangered species conservation in the Dutch Caribbean is likely to vary according to habitat features and how those species utilize those habitats across various life stages. These findings have implications for adaptive MPA management, which should be informed by the ecology and habitat preferences of target species to achieve maximum benefits for biodiversity conservation.

荷属加勒比圣马丁岛附近一个小型海洋保护区内的珊瑚礁鱼类生物多样性和濒危鲨鱼出没情况
海洋保护区(MPAs)是支持保护鲨鱼等受威胁海洋鱼类的常见保护工具。然而,在大加勒比海地区,鲨鱼海洋保护区的建立并不常见,尽管需求和机会都在不断增加。在这项研究中,我们评估了荷属加勒比海圣马丁岛附近鲨鱼和珊瑚礁鱼类生物多样性的发生情况,特别强调了战人浅滩海洋保护区(MPA)内濒危鲨鱼的存在情况。我们利用带饵远程水下视频系统(BRUV)收集了当地 MPA 内外珊瑚礁鱼类和鲨鱼物种的丰度和多样性的非侵入性数据。广义线性模型(GLMs)显示,保护状况对濒危加勒比礁鲨(Carcharhinus perezi)的存在没有显著影响。但是,我们发现深度对鲨鱼的出现有明显影响,栖息地类型对鲨鱼和珊瑚鱼的生物多样性也有影响,其中珊瑚礁栖息地的影响最为明显。这些结果表明,在荷属加勒比海地区,小型沿海海洋保护区对当地濒危物种保护的影响可能会因生境特征以及这些物种在不同生命阶段如何利用这些生境而有所不同。这些研究结果对适应性海洋保护区管理具有启示意义,应根据目标物种的生态学和栖息地偏好进行管理,以实现生物多样性保护的最大效益。

期刊介绍: Environmental Biology of Fishes is an international journal that publishes original studies on the ecology, life history, epigenetics, behavior, physiology, morphology, systematics and evolution of marine and freshwater fishes. Empirical and theoretical papers are published that deal with the relationship between fishes and their external and internal environment, whether natural or unnatural. The journal concentrates on papers that advance the scholarly understanding of life and draw on a variety of disciplines in reaching this understanding. Environmental Biology of Fishes publishes original papers, review papers, brief communications, editorials, book reviews and special issues. Descriptions and submission requirements of these article types can be found in the Instructions for Authors.
