Seasonality Of Reproduction And Embryonic Growth Of Spiny Dogfish (Squalus Acanthias L., 1758) In The Eastern Black Sea, Sefa Ayhan Demi̇rhan, Kadi̇r Seyhan

Turkish Journal of Zoology

The seasonality of reproduction and embryonic development of spiny dogfish (Squalus acanthias) sampled from the Eastern Black Sea were studied. The gestation period of spiny dogfish, starting in August, September and October, takes around 23-24 months. Fertilized females were caught at a depth of 30-45 m in July and August. Females with full-term pups and empty uteri were found at 50-60 m depth, where the temperature was 10 °C. Lengths of pups at birth were around 28-29 cm, whereas their weights ranged from 68 to 78 g. The models of embryonic growth and development of ova were described as TL_e …

During a field excursion in eastern Turkey and the Zanjan province of Iran, 9 rodent species were captured, and the diploid number of chromosomes (2n), the number of autosomal arms (FNa) and the fundamental number (FN) were determined for these species. Microtus schidlovskii with 2n = 60 and FNa = 58 was recorded for the first time from Özalp (Van) and Yüksekova (Hakkari). The karyological record of Meriones vinogradovi in Turkey was also given for the first time.

Turkish Journal of Zoology

The stomach contents of 986 pikeperch, Sander lucioperca (Linnaeus, 1758), collected from Lake Eğirdir in Turkey were investigated between March 2001 and February 2002. Thirteen taxonomic categories were identified from the 1745 prey items analysed. It was determined that the diet of pikeperch in Lake Eğirdir consisted of some fish species (Knipowitschia sp., Aphanius anatoliae anatoliae, Gambusia affinis, Nemacheilus lendli, Carassius gibelio, and Sander lucioperca), odonats (Calopteryx splendens), mysids (Mysis), amphipods (Gammarus) and dipterans (Chironomus).

On Specimens Of Darevskia Armeniaca (Sauria: Lacertidae: Darevskia) Collected From Ardahan, Çeti̇n Ilgaz

Turkish Journal of Zoology

Forty-seven Darevskia armeniaca specimens collected from 2 different localities in Ardahan were examined in terms of pholidosis characters, morphometric measurements and colour-pattern features. The 2 populations were differentiated from one another in terms of the number of supraciliar plates (left-right) (SCPa-SCPb), supralabial plates (left-right) (SRLa-SRLb) and transversal series of ventral plates (TVP) according to the results of the Mann-Whitney U test. An independent t-test based on morphometric measurements revealed significant differences in terms of the head index (HI) between the 2 populations. Regarding pholidosis characters, morphometric measurements and colour-pattern features, specimens collected from the 2 localities showed a similarity to …

Prey Selection By African Catfish Clarias Gariepinus (Burchell, 1822) Larvae Fed Different Feeding Regimes, Erdal Yilmaz, Ahmet Bozkurt, Kaya Gökçek Jan 2006

Prey Selection By African Catfish Clarias Gariepinus (Burchell, 1822) Larvae Fed Different Feeding Regimes, Erdal Yilmaz, Ahmet Bozkurt, Kaya Gökçek

Turkish Journal of Zoology

Live prey selection by African catfish, Clarias gariepinus, larvae was examined under laboratory conditions. Larvae were offered plankton, plankton + trout starter (TS) and plankton + betaine supplemented trout diet (BTS) for 7 days after exogenous feeding. Five larvae were sampled to determine their gut contents and selectivity index for each treatment 15 min after the feeding. It was observed that dry diets (TS and BTS) improved the growth (P < 0.05), but did not significantly influence the prey selection of the larvae. It was determined that African catfish larvae preferred Copepods and Rotaria sp. to other zooplankton species for all feeding regimes.

The Oligochaeta (Annelida) Fauna Of Topçam Dam-Lake (Aydın, Turkey), Seray Yildiz, Süleyman Balik

Turkish Journal of Zoology

With the aim of identifying the oligochaeta fauna of Topçam Dam-Lake, located on the north-western slopes of the East Menteşe Mountains (Aegean region, Turkey), a number of samples were collected monthly between June 1999 and June 2000. Having no previous faunistic studies, some physico-chemical features and oligochaeta fauna of the dam-lake were determined for the first time in this research. Consequently, 11 species were determined, 9 species from Tubificidae, and 2 species from Naididae. Tubificid Limnodrilus hoffmeisteri was the dominant Oligochaeta species and represented 64.64% of the total Oligochaeta community in the dam-lake. There are almost no data on the …

Contribution To The Taxonomical And Biological Characteristics Of Sciurus Anomalus In Turkey (Mammalia: Rodentia), İrfan Albayrak, Ati̇lla Arslan

Turkish Journal of Zoology

This study is based on 62 Sciurus anomalus specimens obtained from Konya, Karaman, Kütahya and Çorum provinces between 1997 and 2002. Some ecological and biological features of the species, including habitat, nest-sites, fur colour, baculum and phallus were investigated. In this species, the chromosome number (2n) is 40. For the taxonomical evaluation of Sciurus anomalus, morphometric data of the specimens were used.

The Adaptive Value Of Aggregation Among Juvenile Caribbean Spiny Lobster: An Evaluation Using Individual-Based Modeling, Thomas W. Dolan Iii, Mark J. Butler Iv Jan 2006

The Adaptive Value Of Aggregation Among Juvenile Caribbean Spiny Lobster: An Evaluation Using Individual-Based Modeling, Thomas W. Dolan Iii, Mark J. Butler Iv

Biological Sciences Faculty Publications

Ontogenetic changes in gregariousness by pre-reproductive animals, like that observed in juvenile Caribbean spiny lobsters (Panulirus argus), may be adaptive and reflect size-specific changes in the effectiveness of aggregation in promoting survival. Alternatively, aggregation may simply result from changes in the distribution or availability of suitable habitat structure, or from other behaviors that enhance survival. There are currently two hypotheses explaining the potential benefits of gregarious behavior in juvenile spiny lobsters, both of which focus on increasing survivorship by reducing predation pressure: the group benefit hypothesis and the guide hypothesis. The group benefit hypothesis argues that aggregations of …

Movement Patterns And Habitat Usage Of Shark Bay Dugongs, David K. Holley Jan 2006

Movement Patterns And Habitat Usage Of Shark Bay Dugongs, David K. Holley

Theses: Doctorates and Masters

In order to define small and large scale spatial and temporal individual movement patterns of dugongs (Dugong dugon) within the Shark Bay World Heritage Property (SBWHP) a total of 19 dugongs were fitted with remote location recording and transmitting devices. Combined locations from all units totalled over 10,000 locations. This spatial and temporal data was used to define movement patterns of dugongs within Shark Bay as well as areas of high use deemed to be indicative of foraging activity. Platform Transmitting Terminals (PTT?s) using the ARGOS location collection system tracked animals over large temporal scales with 4 animals tracked up …
