Abstract

Mikrobna petlja ima neizostavnu ulogu u kruženju tvari u oceanu i zbog abundantnosti i rasprostranjenosti mikroorganizama efikasnost hranidbene mreže uvelike ovisi o njoj. Ne samo u oceanu, nego mikrobna petlja ima veliki utjecaj i globalno, otpuštanjem DMS-a u atmosferu i stvaranjem oblaka te kao mikrobna pumpa i skladištenje ugljika u oceanu kao RDOC. Ona se smatra kao jedno od mogućih rješenja problema globalnog zatopljenja. Nastanak RDOC u oceanu nije još sasvim jasan te su potrebna dodatna istraživanja. Zbog svojeg velikog utjecaja, mikrobna petlja bi se trebala proučavati mikroskopski koliko i makroskopski. Osim toga interakcije između fitoplanktona i mikrobne petlje su puno kompleksnije nego se prvotno smatralo te određuju cijelu hranidbenu mrežu ekosustava.

Abstract (english)

Microbial loop has an inescapable role in circulation of elements in the ocean and because of the abundance and distribution of microorganisms the efficiency of the food web greatly depends on it. Not only in the ocean, but microbial loop has a big impact globally with the release of DMS in the atmosphere and clouds formation and as microbial carbon pump and storage of carbon in the ocean as RDOC. It is considered to be one of the possible solutions to global warming. The creation of RDOC in the ocean is not yet fully clear and further research is needed. Because of its great impact, microbial loop should be studied both microscopically as well as macroscopically. Furthermore, interactions between phytoplankton and the microbial loop are far more complex than previously thought and can determine the entire food web of the ecosystem.
