Fitoplancton y zooplancton en el área marina protegida de Isla Gorgona, Colombia, y su relación con variables oceanográficas en estaciones lluviosa y seca
- 1. Universidad del Valle
Description
We studied the variation in abundance and biomass of plankton in the pelagic environment of Gorgona during October 2010 (rainy season) and March 2011 (dry season), and evaluated their correlation with hydrographic features of temperature, salinity, dissolved oxygen and transparency. Surface waters during both periods were warmer (>26°C) and with low salinity values (<31). At 30m during October the waters were homogeneous, while during March the waters were colder (<18°C), saltier (>34) and presented low oxygen concentrations (<3.0ml/l). 61 genera of phytoplankton and 30 zooplankton groups were identified, with greater values of phytoplankton genus and zooplankton abundance and biomass during March than in October. Bacteriastrum, Chaetoceros, Coscinodiscus, Guinardia, Rhizosolenia and Skeletonema were the phytoplankton genera most frequent in both sampling periods. Copepods were the dominant group of zooplankton, followed by chaetognaths and appendicularia in both periods. Zooplankton biomass was positively associated with surface temperature, salinity at 10m, and transparency of water column, and negatively associated with surface and 30m dissolved oxygen. Rev. Biol.

درسنا التباين في وفرة العوالق وكتلتها الحيوية في البيئة البحرية لجورجونا خلال أكتوبر 2010 (موسم الأمطار) ومارس 2011 (موسم الجفاف)، وقمنا بتقييم ارتباطها بالسمات الهيدروغرافية لدرجة الحرارة والملوحة والأكسجين المذاب والشفافية. كانت المياه السطحية خلال كلتا الفترتين أكثر دفئًا (>26 درجة مئوية) وذات قيم ملوحة منخفضة (<31). في 30 مترًا خلال شهر أكتوبر، كانت المياه متجانسة، بينما كانت المياه خلال شهر مارس أكثر برودة (<18 درجة مئوية) وأكثر ملوحة (>34) وعرضت تركيزات منخفضة من الأكسجين (< 3.0ml/l). تم تحديد 61 جنسًا من العوالق النباتية و 30 مجموعة من العوالق الحيوانية، مع قيم أكبر لجنس العوالق النباتية ووفرة العوالق الحيوانية والكتلة الحيوية خلال شهر مارس مقارنة بشهر أكتوبر. كانت البكتيريا، Chaetoceros، Coscinodiscus، Guinardia، Rhizosolenia و Skeletonema هي العوالق النباتية الأكثر شيوعًا في كلتا فترتي أخذ العينات. كانت مجدافيات الأرجل هي المجموعة المهيمنة من العوالق الحيوانية، تليها chetognaths والزوائد الدودية في كلتا الفترتين. ارتبطت الكتلة الحيوية للعوالق الحيوانية بشكل إيجابي بدرجة حرارة السطح والملوحة عند 10 أمتار وشفافية عمود الماء، وارتبطت سلبًا بالأكسجين المذاب على السطح و 30 مترًا.
