Hayalet yengeç Ocypode cursor (Linnaeus, 1758) yuvalarının insan etkileri altında morfolojik değişimleri
Öz
Hayalet yengeçler, kumsallarda insan etkilerinin tespiti için sıklıkla kullanılan biyoindikatör türlerdendir. Hayalet yengeçler, insan etkileri altında popülasyon dinamiklerinde yuvalama davranışlarında değişiklikler gösterirler, fakat bu değişikliklerin nasıl ve ne şekilde oldukları Türkiye’nin Akdeniz kıyılarında yeterince bilinmemektedir. Bu nedenle, insan baskısı açısından fark gösteren iki farklı alanda Ocypode cursor’ın yuva morfolojileri incelenmiştir. Çalışma neticesinde insan etkilerinin yoğun olduğu bölgelerde yaşayan yengeçlerin, düşük insan etkileri altında yaşayan yengeçlere kıyasla daha küçük, daha dik ve daha basit yuvalar oluşturdukları ortaya çıkmıştır. Bununla birlikte, çalışma alanları arasında yengeç yuvalarının derinliği ve hazneye sahip olma sıklıkları açısından bir fark görülmemiştir. Ek olarak, her iki çalışma bölgesinde de büyük yengeçlerin kumsalın suya daha uzak üst bölgelerine, küçük yengeçlerin ise denize yakın bölgelerine yuvaladıkları ve bu tabakalaşmanın O. cursor için genel bir davranış olduğu anlaşılmıştır. Çalışma neticesinde, O. cursor’ın insan etkileri altındayken popülasyon dinamiklerinin yanı sıra yuva morfolojilerinde ve özelliklerinde de değişiklikler yaptıkları ve hayalet yengeçleri insan etkilerinin tespiti için kullanacak olan çalışmaların bu yuva özelliklerini de göz önüne almaları gerektiği sonucuna ulaşılmıştır.

Ghost crabs are common bioindicator species for human disturbance on sandy shores. Ghost crabs often alter their population dynamics under human disturbance. Ghost crabs, further, alter their burrowing behavior under human influence, however, these changes are not well known on the Turkish coast of the Mediterranean Sea. Therefore, burrowing morphology of Ocypode cursor at two sites that differ in the degree of human disturbance was compared. Ghost crabs created smaller, steeper and simpler burrows at the site under higher human disturbance compared to the crabs living at the sites with lower human influence. Further, there was no difference in the ghost crab burrow depth and the frequency of existence of chambers between sites. Moreover, the results of this study revealed that larger crabs preferred higher parts of the beach at both sites, suggesting that this is common behavior for the populations of O. cursor. Consequently, the results of this study emphasized that O. cursor alter their burrowing morphology and characteristics under human disturbance besides their population demographics; suggesting that studies that focus on the use of ghost crabs for human disturbance should include burrow morphology in their assessments.
