人类活动导致水生物种关键栖息地的丧失速度如此之快,以至于栖息地的改变被认为是对生物多样性的主要威胁。鲨鱼和射线被认为是受威胁第二大的脊椎动物群,它们也遭受了栖息地的丧失,尤其是在苗圃和珊瑚礁相关物种中。在这个意义上,迫切需要采取行动保护物种生存的关键理由,尤其是那些濒临灭绝的人。本研究旨在通过在Dimensions研究数据库中进行的文献综述,收集并提供有关“脆弱”大西洋护士鲨鱼Ginglymostomaciratum的全球分布和栖息地关联的信息。在1950年至2021年之间发表的总共30项研究被保留,因为它们至少定义了与G相关的栖息地类型。大多数研究覆盖了佛罗里达生态区,其中G.ciratum更常见和丰富。珊瑚礁,海草,sandy,洛基,红树林,大型藻类占栖息地协会的大多数,在海洋保护区(MPA)内检测到的栖息地多样性更高。最大深度为75m,温度范围从25°C到34°C,盐度在31至38个百分点之间。新生儿与较浅的栖息地(<20m)有关,主要是珊瑚礁,岩石,大型藻类,沙滩海岸,还有海草,平均温度为26°C,盐度为36ppt。11项研究报告了育种事件和栖息地,其中72.7%在浅水区,主要在MPA内部(90.9%)。我们的发现强调了海洋保护区在保护受威胁物种的基本理由方面发挥的关键作用,比如大西洋护士鲨鱼。主要生态区(例如,只要研究专门旨在评估G.cirratum栖息地关联,东大西洋)在科学文献中的代表性仍然不足。因此,从未来的研究中仍然可以进一步了解保护大西洋护士鲨鱼所需的基本栖息地。考虑到最近IUCN灭绝风险状况的变化。数据不足\'vulnerable\'),迫切需要采取新的保护措施,将生境保护和管理结合起来,并应考虑此处收集的数据。
Human activities have led to the loss of critical habitats for aquatic species at such an accelerated rate that habitat modification is considered a leading threat to biodiversity.
Sharks and rays are considered the second most threatened group of vertebrates that have also suffered from habitat loss, especially in nursery grounds and reef-associated species. In this sense, actions toward the conservation of critical grounds for species survival are urgently needed, especially for those threatened with extinction. This study aimed to gather and provide information on the worldwide distribution and habitat association of the \'vulnerable\' Atlantic Nurse Shark Ginglymostoma cirratum through a literature
review performed at the Dimensions research database. A total of 30 studies published between 1950 and 2021 were retained since they defined at least the type of habitat in which G. cirratum was associated. Most studies covered the Floridian ecoregion, where G. cirratum is more common and abundant. Reefs, seagrass, sandy, rocky, mangrove, and macroalgae accounted for the majority of habitat associations, with a higher diversity of habitats detected within marine protected areas (MPAs). Ginglymostoma cirratum was recorded at a maximum depth of 75 m, temperatures ranging from 25 °C to 34 °C, and salinities between 31 and 38 ppt. Neonates were associated with shallower habitats (<20 m), mostly reefs, rocks, macroalgae, sandy shores, and seagrass, in an average temperature of 26 °C and salinity of 36 ppt. Breeding events and habitats were reported by 11 studies, 72.7% of them in shallow waters, mostly inside MPAs (90.9%). Our findings highlighted the key role played by MPAs in protecting essential grounds for threatened species, such as the Atlantic Nurse Shark. Major ecoregions (e.g., the Eastern Atlantic) are still underrepresented in the scientific literature as long as studies aim specifically to assess G. cirratum habitat association. Thus, further insights into the essential habitats needed to conserve the Atlantic Nurse Shark can still emerge from future studies. Considering the recent IUCN extinction risk status change in G. cirratum (i.e., Data Deficient to \'Vulnerable\'), new conservation measures that integrate habitat protection and management are urgently needed and should consider the data collected herein.
