Lessepsian Fishes Spreading Along The Coasts Of The Mediterranean And The Southern Aegean Sea Of Turkey, Hati̇ce Torcu, Savaş Mater
Turkish Journal of Zoology
The taxonomy and biological characters of 22 Lessepsian fishes living on the coasts of the Eastern Mediterranean and Aegean Sea were examined and 8 species were determined to have commercial importance. Of these, Upeneus moluccensis and Saurida undosquamis have become economic fishes of the Eastern Mediterranean trawl fisheries, having significant stocks. The species previously misidentified as Upeneus asymmetricus was determined to be Upeneus pori. It has been pointed out that new species can be added to the recorded ones by the consequent influx of Red Sea biota into the Levant.

Genetics And Some Aging-Related Mechanisms, Şükran Çakir
Genetics And Some Aging-Related Mechanisms, Şükran Çakir
Turkish Journal of Zoology
Aging can be defined as the time-dependent decline of physiological functions of an organism. Aging, a multifactorial process composed of both genetic and environmental components, is a highly complex biologic phenomenon of great importance. The details of the mechanisms leading to aging are not yet known. All changes in the process of aging have a cellular basis, and perhaps aging should be studied, fundamantally, at the cellular level under defined and controlled environmental conditions. Some genetic approaches have promise for the understanding of this multifactorial process. In this review, some causal hypotheses related to oxidative damage, caloric restriction, mitochondrial mutations, …
Genetic Structure Of Mediterranean Sea Turtle Populations, Yakup Kaska
Genetic Structure Of Mediterranean Sea Turtle Populations, Yakup Kaska
Turkish Journal of Zoology
The mitochondrial DNA (mtDNA) control region sequences of two species ( Caretta caretta and Chelonia mydas) of sea turtles from the Mediterranean were analysed using samples from Northern Cyprus. Only one single haplotype for each species was detected. These results were compared with other published work regarding the genetic structure of sea turtle populations. These results suggest that the Mediterranean population of sea turtles were separated from their Atlantic relatives in the recent past. In order to protect these endangered sea turtles and to preserve the genetic diversity of the sea turtle population in the Mediterranean, individual nesting sites must …

Macrophyte-Dominated Clearwater State Of Lake Mogan, S. Levent Burnak, Meryem Bekli̇oğlu
Macrophyte-Dominated Clearwater State Of Lake Mogan, S. Levent Burnak, Meryem Bekli̇oğlu
Turkish Journal of Zoology
In this study, the water chemistry and zooplankton community of Lake Mogan studied between March 1997 and April 1998. Small-scale industries, crop-farming, urban settlement of the municipality of Gölbaşı with the untreated raw sewage effluent and recreational activities are examples of the human impact within the catchment and the lake, leading to high loading of DIN and TP into the lake via the inflows. However, the natural wetland with the dense reedbeds (Çölovası or Çökek Bataklığı), located on the southern end of the lake, appear to act as a sink for these nutrients. Therefore, the in-lake concentartions of DIN and …

A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu
A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu
Turkish Journal of Zoology
There has been a much debate about the relative importance of the determination of phytoplankton crops by nutrients (bottom-up control) or by zooplankton grazing (top-down control). Wide acceptance of the importance of nutrient concentrations in water quality deterioration has brought about external nutrient control by which eutrophication is, to some extent, reversible, and which has been proved its effectiveness mostly in deep lakes. In shallow lakes its effectiveness has not been as pronounced, owing to internal nutrient loading. Because the non-linearity of responses of biological systems is much more accentuated in small and shallow lakes. The use of profound effects …
Diurnal Variation Of Water Chemistry Andzooplankton In Little Mere, Cheshire, Uk, In 1993 And 1994, Meryem Bekli̇oğlu, Brian Moss
Diurnal Variation Of Water Chemistry Andzooplankton In Little Mere, Cheshire, Uk, In 1993 And 1994, Meryem Bekli̇oğlu, Brian Moss
Turkish Journal of Zoology
In Little Mere, diurnal sampling of the zooplankton at three different habitats in 1993 provided little evidence to support the data of Timms and Moss (10) that cladocerans move out from refugia at night to graze in open water. The floating-leaved water lily, appeared to be more efficient at providing refuge to D. hyalina in the presence of high planktivore fish predation than the submerged plant beds and the open water. This might be due to unfavourable physical and chemical environmental conditions associated with the water lily bed for fish feeding, a possibility supported by the findings of very low …

Some Morphological Features Of The Rectal Sac Of The Silkworm (Bombyx Mori: Bombycidae), Beri̇a Falakali Mutaf, Gamze Turgay
Turkish Journal of Zoology
The silkworm moth escapes from the pupal-protection case by utilizing cocoon-digesting enzymes. The rectal sac was examined in relation to the behaviour of the animal. Pupae and pharate adults were obtained from commercial races and were reared in the laboratory. The ball-shaped rectal sac, easily distinguishable within the abdomen of the silkworm, was found to contain two phased creamy fluid. The occurance and the shape of the organ and the usage of its fluid suggest its role in perforation of the cocoon.
