Abstract

The taxonomical composition of epilithic diatoms was investigated at intertidal zone of Homa lagoon, Aegean sea, Turkey. The stations are located in different littoral zones of the study area and they are different from each other in terms of hydrological respect. The samples contained a mixture of forms growing on the stones themselves, on silt accumulated on the stones and forms epiphytic on other algae, I will refer to this collective community as epilithon. Epilithic diatom species, which constitute the majority of the community were examined from obtained material. A total of 67 diatom taxa belonging to 34 genera were identified to the genus or species level. The species more frequently found in the samples were Cocconeis placentula, Cocconeis scutellum, Mastogloia pumila, Navicula cincta and Navicula crypyocephala var. veneta. Nine of the species identified during the research period seem to be previously unreported for Turkish coastal waters. Morphological characteristics of these species were given in detail information and original photographs.Keywords: Epilithic diatom, species identification, Homa lagoon, Aegean Sea, Eastern Mediterranean Sea. Kıyısal Lagündeki (Ege Denizi, Türkiye) Doğal Substratumda Bulunan Bentik Diyatomelerin Taksonomik Olarak İncelenmesi ÖzetEpilitik diyatomelerin tür kompozisyonu, Homa lagününün (Ege Denizi, Türkiye) kıyısal zonunda incelenmiştir. İstasyonlar, çalışma bölgesinin farklı kıyısal zonlarında yer almaktadır ve hidrolojik açıdan birbirlerinden farklıdır. Alınan örnekler, taş üzerinde bulunan diyatomeleri, taş üzerine biriken kum taneciklerine yapışarak yaşayan diyatomeleri ve diğer algler üzerinde bulunan epifitik diyatomeleri kapsamaktadır ve bu kommunite epiliton olarak ifade edilmektedir. Kommunitenin büyük çoğunluğunu oluşturan epilitik diyatome türleri toplanan materyalde incelenmiş, 34 genusa ait toplam 67 taxa, tür ve genus seviyesinde tanımlanmıştır. Cocconeis placentula, Cocconeis scutellum, Mastogloia pumila, Navicula cincta and Navicula crypyocephala var. veneta türleri örnekleme boyunca sık bulunan türlerdir. Araştırma döneminde saptanan türlerin 9 tanesi Türkiye kıyısal suları için daha önceden rapor edilmemiştir. Bu türlere ait detaylı morfolojik özellikler ve orijinal fotoğraflar çalışmaya eklenmiştir.

Diversity, spatiotemporal distribution, abundance, species composition and habitat preferences of Ostracoda in Akbük and Akdeniz coastal mesosaline lagoons (Muğla, the South Aegean Region, Turkey)

“…As well as ostracod species, many species of plants and animals that characterize lagoon habitats and are found in these lagoons (Table 1). According to these results, and similarly other Aegean Sea coast lagoons (Kevrekidis 1997(Kevrekidis , 2004Kevrekidis et al 2000;Sylaios & Theocharis 2002;Mogias & Kevrekidis 2005;Sabancı 2012), Akdeniz and Akbük have rich biodiversity. However, because brackish water is too salty for most freshwater species and too fresh for most marine species, brackish water lagoons are distinguished for their reduced biodiversity compared to either fully marine, or completely freshwater systems.…”

Particulate Matter Exposure in Agriculture

“…Grain dust may also contain mould spores and if inhaled they can cause a fatal disease called farmer's lung (HSE, 2006). Farmer's lung caused by intoxicant dusts in the lower respiratory tract may result in labor loss, increased health costs, and even death in severe cases (Sabancı, 1999). The wide variety of different exposures may result in numerous respiratory diseases including bronchitis or asthma that may result from or exacerbated by organic dust (grain dusts, animal dander, plant dusts), toxic gases, and infectious agents whereas inorganic dusts and other irritants may exacerbate, if not cause, asthma (Schenker, 2000).…”
