加勒比沿海地区是著名的生物多样性港口，但其价值主要在于其丰富的资源和服务。经济利益通常取代保护努力，将噪音、化学污染和地理干扰等人为相关因素引入生态多样性丰富的沿海地区。尽管已知人类活动对整个栖息地的生物多样性有害，但限制人类活动对沿海种群的保护措施的影响仍未得到充分研究。为了衡量沿海环境保护的效益，我们对波多黎各北部经常光顾（未受保护）和受保护海滩的寄居蟹 Coenobita clypeatus 种群进行了采样。我们通过样线对 1,119 个个体进行了分析，描述了它们的大小以及冬季和夏季的贝壳利用模式。 C.受保护海滩比非受保护海滩的clypeatus种群数量较多（两季P<0.0001）、数量较多（冬季P=0.0006，夏季P<0.0038），且不受季节影响。在受保护的海滩中，贝壳的利用模式更加一致，这可能是由于腹足动物贝壳的可用性更高。这些结果表明，在受保护海滩实施的保护措施促进了该地区寄居蟹的生存、繁殖和生长。通过政府和民间努力扩大受保护的栖息地应加强对保护区生物多样性的保护。
The coastal Caribbean is a well-known harbor for biodiversity, yet it is mainly valued for its ample resources and services. Economic interests typically supersede conservation efforts, introducing anthropogenic-related factors such as noise, chemical pollution, and geographical disturbances into the littoral zone, where ecological diversity is abundant. Although human activity is known to be detrimental to biodiversity across habitats, the effect of conservation measures that limit anthropogenic activity on coastal populations remains understudied. To measure the benefit of conservation in the littoral environment, we sampled populations of the hermit crabCoenobita clypeatusof highly frequented (non-protected) and protected beaches in northern Puerto Rico. We profiled 1,119 individuals by using transects, describing their size and shell utilization patterns during winter and summer. TheC. clypeatuspopulation was larger (P< 0.0001 during both seasons) and more abundant (P= 0.0006 during winter,P< 0.0038 during summer) in the protected beach than in the non-protected beach, with no effect of season. Shell utilization patterns were more consistent in the protected beach, likely due to the greater availability of gastropod shells. These results suggest that the conservation measures implemented in the protected beach promote the survival, reproduction, and growth of hermit crabs in the location. Expansion of protected habitats through governmental and civilian efforts should enhance the conservation of the biodiversity of protected areas.
