Occurrence Of The Alien Species Aspidosiphon (Aspidosiphon) Elegans (Sipuncula) On The Levantine And Aegean Coasts Of Turkey, Şermi̇n Açik

Turkish Journal of Zoology

A total of 37 specimens of Aspidosiphon (Aspidosiphon) elegans were collected at 5 stations located along the Levantine coast of Turkey and at 1 station located near Foça (Aegean Sea).

The population density of this species in the area was found to be 25 ind. M^{-2}. As Aspidosiphon (A.) elegans is a bio-eroder species, its high population density may cause serious damage to coralligenous habitats. This study gives more data regarding the morphological, biological, and ecological features of the species …

The Biology, Nymphal Stages, And Life Habits Of The Endemic Sand Dune Cricket Schizodactylus Inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae), Gökhan Aydin, Andrey Khomutov

Turkish Journal of Zoology

The biology, nymphal stages, and life habits of the endemic dune cricket Schizodactylus inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae) were investigated in this study carried out between 2000 and 2007 in the Çukurova delta (Adana province) and in Alata (Mersin province), Turkey. The study showed that S. inexpectatus, which is a nocturnal insect, passes through 9 nymphal stages, each characterised by its own body size. The present study showed that certain properties of burrows, such as their depths, do not depend on either adult or immature stages of the insect. Food preferences of cannibalistic species of S. inexpectatus were also investigated …

Turkish Journal of Zoology

Dorcatherium majus is one of the 4 Asian species of Dorcatherium found in the Siwaliks of Pakistan. Many fossiliferous sites in the Lower and Middle Siwaliks of Pakistan (Middle and Late Miocene) were visited in the last 14 years and many specimens of D. majus were found. Some specimens are well preserved and some are in a poor state of preservation. Among the collected specimens, 8 were included in this study due to their good preservation. All the selected specimens belong to the lower dentition of D. majus and document intraspecific size variation.


Acute Toxic Effects Of Malathion On The 21^St Stage Larvae Of The Marsh Frog, Ferah Sayim Jan 2008

Acute Toxic Effects Of Malathion On The 21^St Stage Larvae Of The Marsh Frog, Ferah Sayim

Turkish Journal of Zoology

Currently, amphibian decline is accepted as a global problem. One of the most important proposed causes for the decline is the use of agrochemicals, especially pesticides. Nevertheless, information about the impact of pesticides on amphibian populations remains scarce. The present study sought to identify the effects of malathion, an organophosphorus insecticide, on 21^{st} stage larvae of the marsh frog, Rana ridibunda, with an acute toxicity test using a static system. Each experimental group contained 10 healthy larvae and was exposed to different concentrations of technical and formulation grade malathion for 96 h. Concentrations of malathion that caused 50% mortality (LC_{50}) …

Effects Of Cadmium Compounds (Cadmium Para Hydroxybenzoate And Cadmium Chloride) On The Liver Of Mature Mice, Yusuf Ersan, İsmai̇l Ari, Evren Koç

Turkish Journal of Zoology

In this study, 4 experimental groups and 1 control group containing adult mice (Mus musculus var. albinos) were used to examine the effects of 2 different cadmium compounds, namely cadmium para hydroxybenzoate, which was newly synthesized, and cadmium chloride on the liver of mice. In various test concentrations, both cadmium compounds were intraperitoneally injected into adult mice every day for 15 days. With standard histological techniques samples were obtained from the livers of the mice. Slides were prepared and examined with light microscopy (Nikon Eclipse E600) and histopathological structures were observed.

Distribution And Morphology Of Mauremys Rivulata (Valenciennes, 1833) (Reptilia: Testudines: Geoemydidae) In The Lake District And Mediterranean Region Of Turkey, Di̇nçer Ayaz, Abi̇di̇n Budak

Turkish Journal of Zoology

Morphometric measurements and color-pattern features of 62 samples of Mauremys rivulata from the Lake District (Göller Bölgesi) and the Mediterranean Region of Turkey were compared. Between populations, males apparently differed in 10 characters and females in 12 characters (independent t-test), but coefficient of difference (CD) values for these characters were not significant, and sexes were combined into a single group and compared with Aegean M. rivulata with respect to morphometric features. The greatest straight carapace length (SCL) observed in a male and female Aegean specimen was 215.0 mm and 214.0 mm, respectively. This paper also provides the first record of …

Turkish Journal of Zoology

This study was based on 57 beech marten (Martes foina) specimens collected in Turkey between 1994 and 1998. The specimens were divided into 3 age classes as young, juvenile, and adult on the basis of the morphology of the sagittal and lambdoidal crests, and temporal ridges, relative lengths of the interorbital and postorbital constrictions, the degree of wear in molar and canine teeth, baculum weight and structure, pelage color, cranial and bacular measurements, and field notes concerning sexual maturity and lactation. Young, juvenile and adult specimens were readily identified by the shape of the temporal ridges on the skull. These …


Noteworthy Record Of The Mediterranean Water Shrew (Neomys Anomalus) From South-Western Iran (Mammalia: Soricomorpha), Hamid Reza Esmaeili, Ghorbanali Gholamhosseini, Azad Teimory, Boris Krystufek Jan 2008

Noteworthy Record Of The Mediterranean Water Shrew (Neomys Anomalus) From South-Western Iran (Mammalia: Soricomorpha), Hamid Reza Esmaeili, Ghorbanali Gholamhosseini, Azad Teimory, Boris Krystufek

Turkish Journal of Zoology

Three water shrew specimens were collected in the Sheshpir spring (2303 m a.s.l.), Fars province, south-western Iran. In pennial morphology, which is species-specific in the genus Neomys Kaup, 1829, the specimens were indistinguishable from N. anomalus Cabrera, 1907. The Sheshpir spring is located approximately 900 km to the south-south-west of Gorgan, the only site in Iran where N. anomalus has been known to occur so far. The spring is a stony basin with bare banks and poorly developed aquatic vegetation and as such is an atypical habitat for water shrews. It is noteworthy that fish are absent in the spring.

Limnochemical Factors Influencing The Seasonal Population Density, Secondary Production, And Calcium-To-Tissue Ratio In The Freshwater Limpet Septaria Lineata (Archaeogastropoda: Neritidae), Asitava Chatterjee, Manjari Jain, Utpal Singha Roy, Subhra Kumar Mukhopadhyay

Turkish Journal of Zoology

The distribution, secondary production, and calcium:tissue (Ca:tissue) ratio in relation to limno-chemical factors were studied in a freshwater limpet (Septaria lineata) population from the west bank of the River Hooghly, West Bengal, India, for 2 successive years. Total hardness, chloride, pH, and phosphate were shown to be significant in Pearson´s correlations in influencing the abundance of the limpet population. Annual production for the 2 successive years was 10.3 g m^{-2} and 9.5 g m^{-2}, respectively. The annual turnover ratios, the ratios of annual production (P) and annual standing crop (B), ´P/B´, were calculated to be 2.06 and 1.67, while annual …

Turkish Journal of Zoology

This research was carried out in almond orchards (Amygdalus sp.) in Eastern and Southeastern Anatolia in 2003 in order to determine the spider fauna. Among the 129 specimens collected, 21 species belonging to 16 genera and 9 families were recorded at 10 localities with more spiders in the almond orchards in these regions. Among the species, Atea sturmi (Hahn, 1831) is a new record for the araneo-fauna of Turkey. The study was the first on spider fauna in almond orchards in Turkey.
