Batı Ghats ve Doğu Ghats'ın 27 deresindeki Fonksiyonel beslenme grupları, bağırsak içeriği analizine ve ağız kısımlarına dayanarak, mevsimsellik, akarsu düzeni, peyzaj elementleri (LSE)Ephemeroptera, Plecoptera ve Trichoptera mezohabitat (EPT) ile ilişkili olarak incelenmiştir. Çalışmadan toplam 14.168 örnek toplandı ve tanımlandı. Trofik kategorilerin bileşimi, toplayıcıların baskınlığı ile farklı mevsimler arasında hafif bir farklılık gösterdi. Akarsu düzenine göre EPT'nin fonksiyonel besleme gruplarının bolluğunun sonuçları, akarsu düzeni 1 ve 2’de toplayıcıların ve avcıların, 3 ve 4’de toplayıcılar ve filtre besleyicilerin baskın olduğunu gösterdi. LSE elementleri incelendiğinde, toplayıcıların areka cevizinden akan derelerde yüksek, doğal bitki örtüsü içinden akan akarsularda ise düşük olduğu görülmüştür. Fonksiyonel besleme gruplarının akarsu düzeni içindeki dağılımları da analiz edilmiştir. Mezohabitat sonuçları, kazıyıcıların çukurlardaki suda baskın olduğunu, toplayıcıların, yırtıcıların, öğütücülerin ve filtre besleyicilerin akan derelerde olduğunu gösterdi. ANOVA sonuçları, sadece mezohabitatın istatistiki açıdan anlamlı olduğunu gösterdi. Bu çalışmanın sonuçları, çalışmamızın sadece EPT taksonları ile sınırlı olması ve kalın bir şekilde örtülü su akışı alanlarının bulunmaması nedeniyle, Nehir Sürekliliği Konseptinin (RCC) tahminleriyle genel olarak uyuşmamaktadır.

Feeding Patterns and Strategies of Ephemeroptera, Plecoptera and Trichoptera in Relation to Seasonality, Landscape Elements and Mesohabitats

Öz

We inspected functional feeding groups in relationship with seasonality, stream order, Land Scape Elements (LSE), and mesohabitat of Ephemeroptera, Plecoptera, and Trichoptera (EPT) based on gut content analysis and mouthparts in 27 streams of the Western Ghats and the Eastern Ghats. From the study, a total of 14,168 specimens were collected and identified. The composition of trophic categories showed a slight variation among the different seasons with the dominance of collectors. The results of the abundance of functional feeding groups of EPT across stream orders additionally showed the predominance of collectors and predators in-stream orders 1 and 2. Collectors and filter feeders dominate in-stream orders 3 and 4. By examining the LSE elements, it is found that collectors were high in the streams flowing through areca nut and low in the streams flowing through natural vegetation. The distributions of functional feeding groups within the orders were also analyzed. Mesohabitat results showed scrapers were found to be predominant in riffles whereas collectors, predators, shredders, and filter feeders overwhelm in runs. ANOVA results showed that only mesohabitat was found to be significant. The results of the present study did not broadly concur with the predictions of the River Continuum Concept (RCC) because of the lack of thickly canopied headwater stream sites and the limitation of our study to only EPT taxa.
