Abstract

The decrease in erythrocyte size of animals live at high altitudes yields an evolutionary advantage to survive by providing adaptation to colder temperatures and low partial oxygen pressures. We examined the effect of geographical changes on the erythrocyte morphology of two terrapins, Emys orbicularis and Mauremys rivulata, and analyzed whether such erythrocyte characteristics as size and volume changed at high altitudes and different temperatures. We found out that the erythrocyte characteristics varied both within and between the populations. They varied depending on altitude for E. orbicularis and on temperature for M. rivulata. However, the erythrocyte characteristics were not correlated with the environmental parameters, except between sunshine duration and erythrocyte length, size, and nucleus volume for E. orbicularis.

Yükseklik ve Sıcaklığın Emys orbicularis (Linnaeus, 1758) ve Mauremys rivulata (Valenciennes, 1833)’nın Eritrosit Morfolojisi Üzerine Etkisi

Abstract

Yüksek rakımlarda yaşayan hayvanlarda eritrosit boyutlarındaki azalma, düşük sıcaklıklara ve düşük kısmi oksijen basıncına adaptasyon sağlayarak hayatta kalmalarına evrimsel bir avantaj kazandırmaktadır. Coğrafik değişikliklerin eritrosit morfolojisi üzerindeki etkilerini iki tatlısu kaplumbağası türü olan Emys orbicularis ve Mauremys rivulata’da inceledik ve boyut ve hacim gibi eritrosit özelliklerinin yüksek rakım ve farklı sıcaklıklarda değişip değişmediğini analiz ettik. Eritrosit özelliklerinin hem populasyon içerisinde hem de populasyonlar arasında farklılık gösterdiğini belirledik. E. orbicularis için yüksekliğe bağlı olarak, M. rivulata içinse sıcaklığa bağlı olarak değişiklik göstermektedir. Bununla birlikte, E. orbicularis için güneşlenme süresi ile eritrosit uzunluğu, büyüklüğü ve nukleus hacmi arasındaki korelasyon dışında, eritrosit özellikleri ile çevresel parametreler arasında korelasyon görülmemektedir.
