Picoplankton Dynamics during Late Spring 2010 in the South-Eastern Black Sea

Öz:
Mikrobiyal besin zincirinin önemli katılımcısı olan pikoplankton bolluğu ve biyokütlesi çevresel parametreler ile birlikte 2010 yılı geç ilkbahar periyodunda aylık olarak izlenmiştir. Çalışmanın sonuçlarına göre; Synechococcus spp. bolluğu 3,67 x105 - 6,58 x108 hücre L-1, biyokütlesi ise 0,15-23,9 µg C L-1arasında değişmiştir. Synechococcus spp.'ye ait en yüksek bolluk ve biyokütle Haziran 2010'da %1'lik ışık derinliğinde gözlenmiştir. Minimum ve maksimum heterotrofik bakteriyel bolluk ve biyokütle, sırasıyla 1,14x109 - 3,63x109 hücre L-1 ve 6,24-76 µg C L-1arasında değişmiştir. Heterotrofik bakteri bölgede pikoplankton biyokütlesine daha yüksek katkıda bulunurken, pikofitoplankton Haziran 2010'da 30 m'de mikrobiyal besin zincirinde daha önemli bir yer almıştır. Nisan, Mayıs ve Haziranda bakteriyel karbon (30 m'ye entegre edilmiş) fitoplankton karbon oranı sırasıyla, 0,69, 0,24, 0,49 olarak bulunmuştur. 20 m'lik üst su kolonunda fitoplankton karbon biyoması pikoplankton karbon biyokütlesinden 2-3 kat fazla bulunmuştur. Bununla birlikte, bu derinliğin altında ise pikoplankton karbon biyokütlesinde baskın duruma geçmiştir.

Abundance and biomass of picoplankton which are major component of the marine microbial food web with physicochemical environmental variables were monitored monthly in the south-eastern Black Sea during late spring 2010. According to our results Synechococcus spp. abundance range from 3.67 x105 - 6.58 x108 cells L-1 whereas biomass range from 0.15-23.9 µg C L-1. Maximum abundance and biomass of Synechococcus spp. were found at 1% light level at June 2010. The minimum and the maximum heterotrophic bacterial abundance and biomass ranged between 1.14x109- 3.63x109 cells L-1 and 6.24-76 µg C L-1, respectively. Heterotrophic bacteria made a higher contribution to picoplankton biomass on the region, while picophytoplankton became more important within the microbial food web at 30 m in June. The ratio of bacterial carbon (integrated 30 m) to phytoplankton carbon was 0.69, 0.24, 0.49 at April, May and June, respectively. In the top of 20 m water column phytoplankton carbon biomass was 2-3 times higher than picoplankton. Below this depth, however, picoplankton represented the dominant fraction in terms of carbon biomass (50-75%).
