New Records Of Leptostracans (Crustacea, Phyllocarida) From The Eastern Mediterranean, Cengi̇z Koçak, Juan Moreira, Tuncer Katağan
New Records Of Leptostracans (Crustacea, Phyllocarida) From The Eastern Mediterranean, Cengi̇z Koçak, Juan Moreira, Tuncer Katağan
Turkish Journal of Zoology
Knowledge about leptostracans from the Mediterranean Sea is still scarce. Examination of samples collected from the Aegean Sea off Turkey and from Cyprus in the eastern Mediterranean Sea revealed new localities and range extensions for 2 species of leptostracans: Nebalia strausi Risso, 1826, and N. kocatasi Moreira, Koçak, and Katagan, 2007. The record of N. kocatasi is the first for Cyprus and for the Levantine Basin. Additional specimens (Nebalia sp. 1 and Nebalia sp. 2) might prove to belong to 2 new species but the lack of material prevents their formal description.

Turkish Journal of Zoology
Between April 2007 and October 2008 we collected 1995 horse mackerel specimens from the territorial waters of the Bulgarian Black Sea. Age, length, and weight of these specimens were determined to estimate length-weight relationships and age composition. The present study utilized otolith characterization to determine age. The sex ratio was 1:1.36686 (M:F). The prevalent age classes were 2+, 3+, and 4+. The exponent b of equation resulted in the value 3.3046, which indicates that the weight growth is positive allometric. Growth parameters of the von Bertalanffy equation were separately evaluated for females and males as follows: L_{\infinity} = 19.66, K …

Notes On Some Egyptian Lacertidae, Including A New Subspecies Of Mesalina, Involving The Seligmann Effect, Yehudah Leopold Werner, Shoshana Ashkenazi
Turkish Journal of Zoology
These notes on some Egyptian lacertid lizards contribute to faunal data for the planning of biodiversity conservation. Mesalina bahaeldini curatorum n. subsp. is described from Suez, characterized by coloration and larger (fewer) body scales. Range extensions are documented for Acanthodactylus aegyptius, Mesalina olivieri, and M. rubropunctata. The previously reported occurrence of A. opheodurus in Sinai is doubted. The fact that the M. b. curatorum types were collected in the 1820s demonstrates the importance of museum collections.

Changes In Spring Migration Of The Wood Pigeon (Columba Palumbus) In Northwestern Croatia, Zdravko Dolenec, Petra Dolenec
Changes In Spring Migration Of The Wood Pigeon (Columba Palumbus) In Northwestern Croatia, Zdravko Dolenec, Petra Dolenec
Turkish Journal of Zoology
Several papers have shown the sensitivity of birds as monitors of climatic trends. We examined how a short-distance migrant bird, the wood pigeon, has responded to the recent climate change using data from a long-term study (1983-2007) in northwestern Croatia. The wood pigeon arrival dates have become 11.5 days earlier during the study period. This result suggests that the first arrival date of the wood pigeon is influenced by warm springs.

Turkish Journal of Zoology
Fifteen African sharptooth catfish (Clarias gariepinus Burchell, 1822) were collected from the River Asi (River Orontes) in Antakya (Hatay, Turkey) in November 2007, and fish blood samples were examined for the presence of blood parasites. The existence of infection with Trypanosoma (hemoparasite) was identified in 13 out of the 15 fish specimens. Currently there are no records of the presence of any species of Trypanosoma infecting Clarias gariepinus in Anatolia. Thus this study is the first report of Trypanosoma sp. infections in Clarias gariepinus in Turkey.

An Evaluation Of The Distribution Pattern Of The Common Chaffinch (Fringilla Coelebs) In Turkey, Utku Perktaş, Zafer Ayaş
An Evaluation Of The Distribution Pattern Of The Common Chaffinch (Fringilla Coelebs) In Turkey, Utku Perktaş, Zafer Ayaş
Turkish Journal of Zoology
The common chaffinch (Fringilla coelebs) is one of the most common and widespread of the Western Palearctic songbirds and breeds primarily in natural forests in the northern, western, and southwestern parts of Turkey. We reevaluated the distribution of this species in Turkey with recent observational data. Although this species has been considered a breeder in southeastern Turkey, results of this study suggest that it probably does not breed in the region any longer. We examined the effect of climatic (temperature, precipitation, potential evapotranspiration) and topographic (altitude) variables on common chaffinch distribution in Turkey. Our findings show that the presence of …
