Farklı Habitatların Eklembacaklı Komüniteleri Açısından Değerlendirilmesi: Pinus nigra Arnold. (Karaçam) ve Prunus dulcis L. (Badem) Vejetasyonları

Öz

Bu çalışmada, habitat yapısı farklılıklarının eklembacaklı komünite yapısı üzerindeki etkilerinin tespit edilmesi amaçlanmıştır. Bu amaçla, karaçam ve bademlik habitatlar arasındaki farklılıklar mikrohabitat yapısı ve eklembacaklı komünite yapısı açısından incelenmiş, habitat ve eklembacaklılar arasındaki bağlantı değerlendirilmiştir. Burdur İli yakınlarında seçilen söz konusu habitatlarda Nisan ve Mayıs 2012 tarihlerinde örnekleme çalışmaları gerçekleştirilmiştir. Eklembacaklı örneklemeleri, aralarında 5 m mesafe bulunan 4x4’lik 16 adet gömme tuzaklarla yapılmıştır. Mikrohabitat değişkenlerini tespit etmek amacıyla her tuzak noktasının merkezinde ve çevresindeki 9 noktada vejetasyon ve toprak üstü tabakası özellikleri kaydedilmiştir. Eklembacaklı taksonlarının bolluğu ve mikrobitat değişkenleri arasındaki ilişki korelasyon analizi ile değerlendirilmiştir. Yapılan değerlendirmeler, bademlik habitattaki eklembacaklı tür zenginliğinin karaçam habitatına göre oldukça yüksek olduğunu göstermektedir. Eklembacaklı komünitesindeki temel farklılığa neden olan mikrohabitat değişkenleri taç, ot ve ibre örtüşüdür. Taç tabakasının örtüşünün düşük olması bademlik habitatın tabakalılığını ve kompleksliğini arttırmış, bu mikrohabitat özellikleri bademlik habitatı eklembacaklı taksonları açısından daha çekici hale getirmiştir. Sonuç olarak karaçam ve bademlik habitatların eklembacaklı komünitesi açısından büyük oranda farklılık gösterdiği ve bu farklılıkların habitat yapısındaki farklılıktan kaynaklandığı tespit edilmiştir.

Evaluation of Different Habitats with regard to Arthropod Communities: Vegetations of Black Pine (Pinus nigra Arnold) and Almond (Prunus dulcis Mill.)

Öz

In this study, it was aimed to determine effects of differences in habitat structure on arthropod community structure. For this purpose, differences in black pine (Pinus nigra Arnold) and almond (Prunus dulcis ) habitats were analyzed in terms of microhabitat structure and arthropod community structure, and relationship between the habitats and arthropods was presented. Samplings were carried out in habitats chosen near Burdur province during April and May of 2012. Arthropoda samplings were performed by using 16 pitfall-traps that were placed with 5 m intervals in 4x4 grids. To determine microhabitat variables, features of vegetation and surface layer were recorded in 9 points in center and around of each traps. Relationship between abundance of arthropod taxa and microhabitat variables were evaluated with correlation analysis. Evaluations displayed that species richness of arthropods in almond habitat was higher than black pine habitat. Microhabitat variables caused differences in arthropod communities between habitats were found as cover of canopy, grass and needle. The lower canopy cover increased stratification and complexity of almond habitat and these microhabitat features made this habitat more attractive for arthropod communities. As a result, it was determined that black pine and almond habitats showed substantially differences in terms of arthropod communities and these differences were due to habitat structure.
