Nutrition is one of the main processes in living beings because it provides
energy. Amphibians are an essential link in food chains, but they have not
been sufficiently studied. It is believed that most anuran larvae and tadpoles
are omnivorous, but the trophic status of many tadpoles has not been precisely
determined. Microplastics (MPs) are one of the major threats to aquatic
ecosystems and can be ingested by various groups of aquatic organisms,
such as plankton, shellfish, fish, and amphibians, but current knowledge of
MPs occurrence in these aquatic organisms is still scarce. In this research,
the intestinal contents of tadpoles of four anuran species were analyzed to
assess nutrition and the presence of microplastics. The results show that
the largest percentage of tadpoles’ diet consists of diatoms from the genera
Achnanthidium and Navicula, and detritus. The remains of some invertebrates
were also present in the material. Microplastic analysis proved the presence of
...
MPs in all investigated samples. The data obtained in this research represent
the first concrete results due to which it is necessary to continue extensive
research at several levels.
Ishrana je jedan od ključnih procesa živih bića jer predstavlja glavni izvor
energije. Vodozemci su važna karika u lancima ishrane, ali nisu dovoljno
proučavani. Veruje se da je većina larvi bezrepih vodozemaca, odnosno
punoglavaca, omnivorna, ali trofički status mnogih punoglavaca nije precizno
utvrđen. Mikroplastika (MP) je jedan od glavnih zagađivača u vodenim
ekosistemima pa je različite grupe vodenih organizama, kao što su plankton,
školjke, ribe i vodozemci mogu uneti u organizam, ali trenutno znanje o
prisustvu MP u ovim vodenim organizmima je još uvek nedovoljno. U ovom
istraživanju analiziran je sadržaj creva punoglavaca četiri vrste bezrepih
vodozemaca kako bi se procenila ishrana i prisustvo mikroplastike. Rezultati
pokazuju da najveći procenat ishrane punoglavaca čine silikatne alge iz
rodova Achnanthidium i Navicula, kao i detritus. Takođe, u sadržaju creva
bili su prisutni i ostaci nekih beskičmenjaka. Analize mikroplastike dokazale
su da su čestice MP pris...utne u svim ispitivanim uzorcima. Podaci dobijeni
u ovom istraživanju predstavljaju prve konkretne rezultate zbog kojih je
neophodno nastaviti dodatna istraživanja na više nivoa
