İzmir Körfezi' nde 1998-2001 yılları arasında fitoplanktonik tür çeşitliliği değişimi

Bu çalışmada Izmir Körfezi'nin fitoplankton tür çeşitliliği (Shannon-Wiener) değişimleri iç, orta, dış körfezde yer alan üç istasyonda vertikal ve kantitatif olarak 1998-2000 ve 2001 yıllarında incelendi. Atık Su Arıtma Tesisinden sonra tür çeşitliliğinde, istatistiksel olarak önemli pozitif artışın meydana geldiği saptanmıştır. Student-t testleri ve diskriminant analizleri belirli istasyonlar ve yıllar arasında, istatistiksel olarak p

The phytoplanktonic species diversity variations in the bay of İzmir between the years 1998-2001

The phytoplanktonic species diversity variations in the Bay of Izmir between the years 1998-2001. In this study, the phytoplanktonic species diversity variations were investigated vertically and quantitavely in there stations located in the inner, middle and outer bay of Izmir in 1998-2001 years. It was determined that statistically significant positive increases in the species diversity occured after the waste water treatment activities. Student's t-tests and discriminant analyses realized among the stations and years gave statistically significant differences at p<0.05 probability level. These results indicated that the considerable improvements should be expected in the next years.
