Abstract

The abundance of the
peracarid crustacean fauna were studied on a spatial scale of Gokceada Island
which is located Northern Aegean Sea. Samples were collected seasonally from 13 coastal stations at depth
0.1-0.5 m, during years of 2010 and 2011. The surface was scraped by means 20 x
20 cm quadrats and sieving 0.5 mm mesh size. Result of identified and counting
all peracarid species, a total of 142,906 individuals/m² were
obtained belonging to 88 species and 66 of them were new record for the
island’s fauna. Amphipods were the dominant group both in terms of species
Margalef richness and abundance. Ampithoe
ramondi, Hyale schmidti and Elasmopus
brasiliensis were the most abundant species. Number of species, density,
richness, evenness, diversity of stations and similarity are also discussed.

Gökçeada (Ege Denizi)’nın Kayalık Üst Inftalittoral Kıyılarının Peracarid Crustacea Türleri

Abstract

Peracarid crustacea faunanın
bolluğu, Kuzey Ege Denizi'nde yer alan Gökçeada Ada'nın mekansal ölçeğinde
incelenmiştir. Örnekler, 2010 ve 2011 yıllarında 0,1-0,5 m derinliğindeki 13
kıyı istasyonundan mevsimsel olarak toplanmıştır. Numuneler, 20 x 20 cm olan
kuadrat aracılığıyla sert zeminden kazınmış ve 0,5 mm göz açıklığına sahip
elekten geçirilmiştir. Tüm peracarid türlerin, tür teşhisi ve sayılmaları
sonucunda, 88 türe ait toplam 142.906 birey/m² elde edilmiş ve
bunların 66’sı adanın faunası için yeni kayıttır. Amphipodlar hem tür
zenginliği hem de bolluk açısından baskın grup olduğu saptanmıştır. Ampithoe ramondi, Hyale schmidti ve Elasmopus brasiliensis en bol bulunan
türlerdir. Çalışmada ayrıca tür sayısı, birey sayısı, zenginlik indeksi,
düzenlilik indeksi, çeşitlilik indeksi ve istasyonların benzerlikleri de
tartışılmıştır.
