Britaniyadagi tyulenlarning rangi to‘q sariqqa o‘zgarib qoldi

Angliyaning Esseks grafligidagi tyulenlarning tabiiy kulrang tusi to‘q sariqqa o‘zgargani olimlarning e’tiborini tortdi. Avvaliga hayvonlarni muhofaza qiluvchi tashkilot xodimlari hayvonlar kasal bo‘lib qolgan degan taxminga borishdi. Biroq aniqlanishicha, hayvonlarning bu kabi rangga kirishiga mahalliy tuproq tarkibidagi temir oksidi sabab bo‘lgan, deb xabar berdi “Nauka”.

Tyulenlar butun vaqtini loyda ag‘anab yotishga sarflaydi, natijada zangdagi temir oksidining zarralari ularning yungiga yopishib qolgan. Esses grafligi atrof-muhit muhofazasi jamg‘armasining zoologlarini ta’kidlashicha, hayvonlarga hech nima xavf solmayapti — tullash davrida ular o‘zlarining tabiiy rangini qayta tiklashadi.
