Patrones de distribución y tasas de bioerosión del erizo <i>Centrostephanus coronatus</i> (Diadematoida: Diadematidae), en el arrecife de Playa Blanca, Pacífico colombiano

Description

Regular sea-urchins are one of the main bioeroding organisms affecting coral reefs around the world. The abundance, distribution and bioerosion rate of the sea-urchin Centrostephanus coronatus, were determined in different reef zones of Playa Blanca fringing reef (Gorgona Island, Colombian pacific coast) during 1997 and 1998. The erosion rates were determined calcinating the gut content of the sea-urchins to eliminate all organic components and preserve the inorganic portion of calcium carbonate. C. coronatus showed the highest densities towards the central zones of the reef (plain-crest and front) (12.4 ind/m2; range 0-48 ind/m2). The highest mean bioerosion rate was 0.103 kgCaCO3/m2/yr in the reef plain-crest (0-0.69 kgCaCO3/m2/yr). In the other zones, (back reef and reef front) the mean bioerosion rates were 0.071 (range 0-0.39) and 0.052 (range 0-0.31) kgCaCO3/m2/yr respectively. According to the present data, it can be seen that the destruction of coralline skeletons, produced in this reef by sea-urchins is rather low, compared with the abrasion caused by these organisms in other places of the world. However, the combined action of C. coronatus and other bioeroding organisms (borers and grazers). along with some adverse environmental factors to corals, can be causing a negative balance between normal processes of reef accretion-destruction in Gorgona Island reefs.

القنافذ البحرية المنتظمة هي واحدة من الكائنات الحية الرئيسية التي تؤثر على الشعاب المرجانية في جميع أنحاء العالم. تم تحديد الوفرة والتوزيع ومعدل التآكل البيولوجي للسفينة البحرية Centrostephanus coronatus، في مناطق مختلفة من الشعاب المرجانية في شاطئ بلايا بلانكا (جزيرة جورجونا، ساحل المحيط الهادئ الكولومبي) خلال عامي 1997 و 1998. تم تحديد معدلات التآكل من خلال حساب محتوى الأمعاء في قنافذ البحر للقضاء على جميع المكونات العضوية والحفاظ على الجزء غير العضوي من كربونات الكالسيوم. أظهر C. coronatus أعلى كثافة نحو المناطق المركزية للشعاب المرجانية (العرف العادي والجبهة) (12.4 بوصة مربعة/م 2 ؛ النطاق 0-48 بوصة مربعة/م 2). كان أعلى متوسط لمعدل التآكل البيولوجي 0.103 كجم من ثاني أكسيد الكربون/م 2/سنة في الشعاب المرجانية ذات القشور العادية (0-0.69 كجم من ثاني أكسيد الكربون/م 2/سنة). في المناطق الأخرى، (الشعاب المرجانية الخلفية والشعاب المرجانية الأمامية) كان متوسط معدلات التآكل البيولوجي 0.071 (النطاق 0-0.39) و 0.052 (النطاق 0-0.31) كجم من ثاني أكسيد الكربون/م 2/سنة على التوالي. وفقًا للبيانات الحالية، يمكن ملاحظة أن تدمير الهياكل العظمية المرجانية، التي تنتجها قنافذ البحر في هذا الشعاب المرجانية منخفض إلى حد ما، مقارنة بالتآكل الذي تسببه هذه الكائنات الحية في أماكن أخرى من العالم. ومع ذلك، فإن العمل المشترك لـ C. coronatus والكائنات الحية الأخرى المتعرجة بيولوجيًا (الحفارون والرعاة)، إلى جانب بعض العوامل البيئية الضارة للشعاب المرجانية، يمكن أن يتسبب في توازن سلبي بين العمليات الطبيعية لتدمير تراكم الشعاب المرجانية في شعاب جزيرة جورجونا.
