Abstract

The development and maintenance of the physical structure of coral reefs depends on the balance between production (accretion) and removal (erosion) of CaCO3 produced mainly by reef-building corals. This calcareous material may be removed from the coral skeleton by means of physical, chemical, or biological agents, with the latter being the most influential. Despite being important, bioerosion studies on coral reefs from the Pacific coast of Mexico are scarce. In this study, we determined the volume and percentage of CaCO3 removed through bioerosion from the main massive coral species, Pavona gigantea, Porites lobata, and Porites panamensis, in the Islas Marietas and Isla Isabel National Parks (Mexico). We also evaluated the effect of extrinsic (morphology, sex, and age) and intrinsic (depth and location) factors on bioerosion. The buoyant weight technique was used to estimate internal bioerosion parameters and CaCO3 skeletal density. At the species level, P. gigantea showed volume of bioerosion values of 71.31 ± 32.35 cm3 (27.28 ± 18.05% of internal bioerosion); Po. lobata, 26.60 ± 24.87 cm3 (16.87 ± 16.31%); and Po. panamensis, 29.6 ± 14.61 cm3 (31.127 ± 29.43%). At the genus level, Pavona exhibited the highest bioerosion and skeletal density values (1.61 g·cm–3). Regarding morphology, bioerosion was higher in massive corals, but regarding age, it was higher in adult colonies (10–26 years). Islas Marietas National Park showed the highest values for volume and percentage of bioerosion. The results suggest that coral reefs on the Pacific coast of central Mexico are undergoing a high degree of inconspicuous erosion by internal bioeroders and its variability is controlled by both intrinsic and extrinsic factors. If this effect continues to rise, it could threaten the long-term maintenance of coral communities, modifying the carbonate flux equilibrium and the ecological functionality of coral reef ecosystems.

与热带东北太平洋珊瑚礁群落相关的大型珊瑚的内部生物侵蚀:内在和外在因素的影响

珊瑚礁物理结构的发展和维持取决于主要由造礁珊瑚产生的碳酸钙的产生(吸积)和去除(侵蚀)之间的平衡。这种钙质物质可以通过物理、化学或生物制剂从珊瑚骨架中去除，其中生物制剂的影响最大。尽管很重要，但对墨西哥太平洋沿岸珊瑚礁的生物侵蚀研究很少。在这项研究中，我们测定了墨西哥玛丽埃塔斯岛和伊莎贝尔岛国家公园的主要大型珊瑚物种Pavona gigantea、Porites lobata和Porites panamensis通过生物侵蚀去除CaCO3的体积和百分比。我们还评估了外在因素(形态、性别和年龄)和内在因素(深度和位置)对生物侵蚀的影响。利用浮力重量技术估计内部生物侵蚀参数和CaCO3骨骼密度。在物种水平上，巨茶的生物侵蚀体积值为71.31±32.35 cm3(占内部生物侵蚀的27.28±18.05%);阿宝。Lobata, 26.60±24.87 cm3(16.87±16.31%);和阿宝。巴拿马，29.6±14.61 cm3(31.127±29.43%)。在属水平上，黄颡鱼的生物侵蚀和骨密度最高(1.61 g·cm-3)。就形态而言，大型珊瑚的生物侵蚀程度更高，但就年龄而言，成年珊瑚(10-26岁)的生物侵蚀程度更高。玛丽埃塔斯岛国家公园的生物侵蚀量和百分比最高。结果表明，墨西哥中部太平洋沿岸的珊瑚礁正遭受内部生物侵蚀物的高度不明显侵蚀，其变异受内在和外在因素的双重控制。如果这种影响持续上升，可能会威胁到珊瑚群落的长期维持，改变碳酸盐通量平衡和珊瑚礁生态系统的生态功能。

期刊介绍： A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format. CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience. So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
