NEUSTONIC MARINE MICROPLASTICS ANDZOOPLANKTON IN THE COASTAL WATERS OFCABRERA MPA (North-Western MediterraneanSea)Valentina Fagiano∗1, Carme Alomar2, Montserrat Compa Ferrer3, GuillemMateu-Vicens1, and Salud Deudero31Universidad de las Islas Baleares – Cra. de Valldemossa, km 7.5.

As towhich are the effects of MP abundances on zooplanktonic community assemblage and com-position, particularly in coastal ecosystems, it is still an open question.The present study addresses MP distribution and composition within Cabrera MPA (north-western Mediterranean Sea) as well its effects on local zooplanktonic community assemblage.MP average abundances found within Cabrera MPA [0.35 (± 0.29) items/m3] showed highervalues than those reported for the majority of western Mediterranean Sea basins and forthe closest more anthropized area of Mallorca [0.16 (± 0.29) items/m3]. A micro-scale ac-cumulation area was detected within Cabrera MPA presenting an MP abundance [19.32 ±(14.45) items/m3] higher than those reported for the subtropical gyres by previous studies.MP composition suggested far contamination sources as predominant.Moreover, MP appeared able to influence the local zooplanktonic community assemblagewithout altering the zooplankton average abundance. An interesting positive correlationwas found between MP and the abundance of the planktonic stage (Tretomphalus) of theforaminifer Rosalina globularis. This species seems able to utilize MP for its dispersion, whilea negative correlation with Copepoda abundance was detected suggesting a role of this taxain MP removal from surface waters.This work highlights an important and complex interaction between zooplankton and MP,being able to mutually influence their distribution and composition. Moreover, results con-firm that MPAs are not protected from MP pollution.∗Speakersciencesconf.org:micro2020:334376Keywords: Microplastics, MPAs, Zooplankton, Microplastic: zooplankton ratios, Balearic.
