Effects Of Hydroperiod On Metamorphosis In Rana Sphenocephala, Travis J. Ryan, Christopher T. Winne Jan 2001

Effects Of Hydroperiod On Metamorphosis In Rana Sphenocephala, Travis J. Ryan, Christopher T. Winne

Scholarship and Professional Work - LAS

Hydroperiod, the time a temporary pond holds water, is an important factor influencing recruitment in amphibian populations and structuring amphibian communities. We conducted an experiment to test the effect of hydroperiod on metamorphic traits of the southern leopard frog (Rana sphenocephala), a common amphibian in the southeastern United States. We reared larval R. sphenocephala in artificial ponds at a density of 32 larvae per tank (initial volume = approximately 650 liter). We dried the tanks according to natural patterns, using three different hydroperiods (60, 75 and 90 d). Experimental hydroperiods had a significant effect on the number of …

Studies On Sediment Toxicity Bioassays Using Chironomus Thummi K., 1911 Larvae, Levent Bat, Mehmet Akbulut Jan 2001

Studies On Sediment Toxicity Bioassays Using Chironomus Thummi K., 1911 Larvae, Levent Bat, Mehmet Akbulut

Turkish Journal of Zoology

The acute toxicity of zinc, copper and lead to freshwater dipteran Chironomus thummi larvae was evaluated by static bioassays, calculating the LC_{50} (lethality concentration for 50%). Mortality increased with increasing concentrations of zinc, copper and lead. The LC_{50}s of Zn, Cu and Pb for survival were 11.2, 19.1 and 14.3 µg g^{-1}, respectively. The results indicated that Zn had the greatest toxicity, followed by Pb and Cu. Individual weight increased with increasing Cu, Zn and Pb concentrations. The results are discussed and compared with those of other studies.

The Effects Of Precocene Ii On The Fine Structure Of Corpus Allatum In Adult Female Anacridium Aegyptium L. (Orthoptera, Acrididae), Gürsel Ergen Jan 2001

The Effects Of Precocene Ii On The Fine Structure Of Corpus Allatum In Adult Female Anacridium Aegyptium L. (Orthoptera, Acrididae), Gürsel Ergen

Turkish Journal of Zoology

In this study, the effects of the antijuvenile hormone Precocene II on the corpus allatum of adult females of Anacridium aegyptium L. (Orthoptera) were investigated with electron microscopy. In the insects, topically treated with 500 µg precocene II, the corpora allata did not show marked atrophy or destruction. After 10 or 20 days of precocene II treatment, the ultrastructural changes of especially the nuclei, mitochondria, endoplasmic reticulum membranes, Golgi complexes and some other intracellular organelles in the gland cells, probably reflect a moderate sensitivity to this compound.

Turkish Journal of Zoology

The age and growth parameters of red bandfish (Cepola rubescens L.,1766) were determined from the specimens collected in İzmir Bay (Aegean Sea) between January 1996 and February 1997. Mean length at age data from otolith readings were used to estimate the growth parameters of the von Bertalanffy equation: for females, L_{\infity}=78.48 cm, K=0.17 y^{-1}, t_o=0.0972 y, W_{\infity}=110.00 g, K=0.10 y^{-1}, to=0.1033 y and for males L_{\infity}= 83.22 cm, K=0.16 y^{-1}, t_o=0.0888 y ; W_{\infity}=129.83, K=0.0818 y^{-1}, to=-0.4117 y. Length-weight relationships was estimated for males and females to be W=0.07723 L^{1.11217} and W=0.029154 L^{1.38434}, respectively. The observed mean total length and …

Excretory Products Of Green Mussel Perna Viridis L. And Their Implications On Power Plant Operation, J. Gunasingh Masilamoni, Jayapaul Azariah, K. Nandakumar, K. Samuel Jesudoss, K. K. Satpathy, K. V. K Nair

Turkish Journal of Zoology

Excretion in marine animals is considered an important factor in assessing physiological status. Perna viridis, a widely distributed bivalve species, was found to be the dominant (>70%) organism in the seawater intake tunnel of Madras Atomic Power Station (MAPS). The excretion patterns (ammonia, nitrite, phosphate and fecal matter production) of three different size groups (4-5 cm, 6-7 cm, and 8-9 cm shell length) of P. viridis were studied in the laboratory at different salinities (15, 20, 25, 30 and 34 ppt). The amount of excreted products was positively related to the size of the mussels. At ambient salinity, the …

Turkish Journal of Zoology

In this study, some biological characteristics such as age and sex composition, growth in length and weight, age-length, age-weight and length-weight relationships, condition factor spawning time, age of sexual maturity, and fecundity of Silurus triostegus in Atatürk Dam lake were investigated. The percentage of females was 48.3% and that of males 57.7% out of 623 specimens belonging to age groups I-XI. Isometric growth patterns were proved from the length-weight relationships. It was estimated that the females had higher Lo (202.85 cm) and lower low K (0.046871) values than males (Lo 113.98 cm and K = 0.101972). Mean condition factors of …

Erythrocyte Measurements Of Some Scincids From Turkey, Mehmet Kutsay Atatür, Hüseyi̇n Arikan, İ. Ethem Çevi̇k, Ahmet Mermer

Turkish Journal of Zoology

The aim of this study was to determine the erythrocyte and nucleus sizes of some scincids (Ablepharus chernovi, Chalcides ocellatus, Eumeces schneideri, Mabuya aurata, Mabuya vittata, and Ophiomorus punctatissimus) from Turkey by means of blood smears stained with Wright's stain. The largest erythrocytes were observed in the smears of E. schneideri, and the smallest in M. vittata, while the largest nuclei were observed in E. schneideri and the smallest were in M. aurata. In terms of the studied species, the nucleus and erythrocyte sizes were found to be correlated (r= 0.302, P< 0.01).

Karyotype Of Eptesicus Serotinus (Schreber, 1774) In Turkey (Mammalia: Chiroptera), Nursel Aşan

Turkish Journal of Zoology

In order to investigate the conventional karyotype of Eptesicus serotinus (Schreber, 1774) in Turkey, four specimens were karyotyped. It was determined that the diploid number was 2n=50, the number of autosomal arms was FN=50, the X chromosome was large submetacentric, and the Y chromosome was dot-like acrocentric and the smallest chromosome of the set. All of the autosomes were acrocentric. A secondary constriction on a medium-sized acrocentric pair was encountered in most of the metaphase spreads examined.
