Znanstvenici Instituta za oceanografiju i ribarstvo u Splitu proveli su istraživanje o životu školjkaša, te su došli do zanimljivih spoznaja.

- Jeste li ikad razmišljali koliko dugo žive školjkaši?

Iako postoji mnogo vrsta koje žive samo nekoliko godina, Jadransko more nastanjuju vrste koje žive i više desetljeća. Brbavica (Venus verrucosa) je upravo jedna od tih vrsta.

Istraživanje naših znanstvenika potvrdilo je da brbavica može živjeti značajnije duže nego što se do sada mislilo. Datiranje radioaktivnim ugljikom i analiza linija rasta u presjecima ljuštura utvrdili su do sad maksimalnu zabilježenu starost ove vrste od 29 godina - što je čak 13 godina više od podataka objavljenih u znanstvenoj literaturi.

Koliko dugo žive brbavice?

---

Ovako stare jedinke izuzetno su rijetke i činile su manje od 2% analiziranih jedinki.

Dobiveni rezultati jasno pokazuju da se starost ne može procjenjivati iz veličine ljuštura, jer su školjkaši sličnih dužina (~5 cm) imali procijenjenu starost od 10 do 29 godina - poručili su iz IZORa.

Istraživanje je provedeno u sklopu HRZZ BivACME projekta, a rezultati su objavljeni u znanstvenom časopisu Fisheries Research.

Koliko dugo žive brbavice?

 ) ) [bgPosition] => [text] => {OCMSplitter}

Znanstvenici Instituta za oceanografiju i ribarstvo u Splitu proveli su istraživanje o životu školjkaša, te su došli do zanimljivih spoznaja.

- Jeste li ikad razmišljali koliko dugo žive školjkaši?

Iako postoji mnogo vrsta koje žive samo nekoliko godina, Jadransko more nastanjuju vrste koje žive i više desetljeća. Brbavica (Venus verrucosa) je upravo jedna od tih vrsta.

Istraživanje naših znanstvenika potvrdilo je da brbavica može živjeti značajnije duže nego što se do sada mislilo. Datiranje radioaktivnim ugljikom i analiza linija rasta u presjecima ljuštura utvrdili su do sad maksimalnu zabilježenu starost ove vrste od 29 godina - što je čak 13 godina više od podataka objavljenih u znanstvenoj literaturi.

Ovako stare jedinke izuzetno su rijetke i činile su manje od 2% analiziranih jedinki.

Dobiveni rezultati jasno pokazuju da se starost ne može procjenjivati iz veličine ljuštura, jer su školjkaši sličnih dužina (~5 cm) imali procijenjenu starost od 10 do 29 godina - poručili su iz IZORa.

Istraživanje je provedeno u sklopu HRZZ BivACME projekta, a rezultati su objavljeni u znanstvenom časopisu Fisheries Research.

život školjkašaSplitski znanstvenici proveli zanimljivo istraživanje: ‘Brbavica je dugovječnija nego se mislilo...‘

Znanstvenici Instituta za oceanografiju i ribarstvo u Splitu proveli su istraživanje o životu školjkaša, te su došli do zanimljivih spoznaja.

- Jeste li ikad razmišljali koliko dugo žive školjkaši?

Iako postoji mnogo vrsta koje žive samo nekoliko godina, Jadransko more nastanjuju vrste koje žive i više desetljeća. Brbavica (Venus verrucosa) je upravo jedna od tih vrsta.

Istraživanje naših znanstvenika potvrdilo je da brbavica može živjeti značajnije duže nego što se do sada mislilo. Datiranje radioaktivnim ugljikom i analiza linija rasta u presjecima ljuštura utvrdili su do sad maksimalnu zabilježenu starost ove vrste od 29 godina - što je čak 13 godina više od podataka objavljenih u znanstvenoj literaturi.
