Kuş Çeşitliliğini Etkileyen Çevresel Faktörlerin Belirlenmesi

Çalışmanın amacı: Bu çalıĢmanın ana amacı kuĢ çeĢitliliğini etkileyen çevresel faktörlerin belirlenmesidir. Çalışma alanı: ÇalıĢma Batı Akdeniz Bölgesinin iç kesimlerinde yer alan Isparta ilinin Çandır yöresinde gerçekleĢtirilmiĢtir. Materyal ve yöntem: ÇalıĢmada 2016 yılında aylık olarak düzenli Ģekilde gerçekleĢtirilen arazi gözlemlerinden elde edilen 43 örnek alan verisi kullanılmıĢtır. Her bir örnek alanda noktada sayım tekniği ile gözlemler gerçekleĢtirilmiĢtir. ÇalıĢmada alfa çeĢitlilik indeksleri hesaplanarak korelasyon analizi ile bu indisler ile iliĢkili olan çevresel değiĢkenler belirlenmiĢtir. Temel sonuçlar: Alfa çeĢitlilik indeksleri ile hem çevresel değiĢkenler hem de iklim değiĢkenleri arasında önemli iliĢkiler (p=0.05) tespit edilmiĢtir. Temel BileĢenler Analizi kullanılarak alfa çeĢitlilik indislerinin birbirleri ile olan iliĢkileri ortaya koyulmuĢtur. Tür zenginliği, Shannon indeksi, ve Brillouin indeksi değiĢkenler ile en yüksek korelasyon gösteren değiĢkenler olarak tespit edilmiĢtir. Araştırma vurguları: Ekosistemlerin hassas türlerinden olan kuĢlara ait çeĢitliliği etkileyen faktörlerin belirlenmesi, gelecekteki değiĢimlerin tespiti ve izlenmesi açısından büyük önem taĢımaktadır. Özellikle modelleme çalıĢmaları için parametre seçimi bakımından düĢünüldüğünde bu önem daha da artmaktadır. Bu nedenle, bu araĢtırmanın sonuçlarının hem Çandır Ġlçesi'nde yapılan çalıĢmalar açısından hem de kuĢ çeĢitliliği üzerine yapılmıĢ çalıĢmalar açısından önem arz edeceği düĢünülmektedir.

Determining Environmental Factors Affecting Bird Diversity

Aim of study: The main purpose of the study is to determine the site factors affecting bird diversity. Area of study: This study was performed in the Çandır District, Isparta which is located inner part of the Western Mediterranean region. Material and methods: In present study, Observations were conducted regularly in a total of 43 sample sites in Çandır District, throughout each month in 2016. Also, each sample site was observed using point-counting techniques from the direct observation techniques. In the present study, alpha diversity (Species richness, Menhinick, Margalef, Shannon-Wiener, Brillouin, Simpson, Berger-Parker, and Fisher’s Alpha) values were calculated, and significant variables were determined by using correlation analysis. Main results: A significant correlation (p=0.05) was determined between alpha diversity values and both environmental and climatic variables. Principal component analysis (PCA) was used to compare alpha diversity indexes with each other. Species richness, Shannon, and Brillouin indexes were determined as the variables having the strongest correlation with environmental variables. Highlights: A better understanding of factors affecting bird species diversity, which are sensitive species of ecosystems, is of great importance for the detection and monitoring of future changes. Especially when it is considered in terms of parameter selection for modeling studies, the mentioned importance increases even more. Therefore, it is thought that the results of this research will be important both in terms of studies conducted in Çandır District and in terms of studies on bird diversity.
