Neoteny And The Plesiomorphic Condition Of The Plesiosaur Basicranium, F. Robin O’Keefe Jan 2006

Neoteny And The Plesiomorphic Condition Of The Plesiosaur Basicranium, F. Robin O’Keefe

Biological Sciences Faculty Research

The purpose of this paper is to describe the condition of the braincase in stratigraphically early and morphologically primitive plesiosaurs. Information on the braincase of plesiomorphic taxa is important because it establishes the polarity of characters occurring in more derived plesiosaurs. This paper begins with a short review of braincase anatomy in stem-group sauropterygians. Data on braincase morphology of the plesiomorphic plesiosaur genera Thalassiodracon and Eurycleidus are then presented and interpreted via comparison with other plesiosaurs, stemgroup sauropterygians, and stem diapsids (Araeoscelis). Early diapsids are relevant because plesiosaur skulls more closely resemble early diapsids than stem-group sauropterygians in several key …

Apparent Digestibility In Vicunas Fed With Soft Straw And Alfalfa In The C.E.A.C., Felisa Capriles Apaza Jan 2006

Apparent Digestibility In Vicunas Fed With Soft Straw And Alfalfa In The C.E.A.C., Felisa Capriles Apaza

Theses and Dissertations

South American camelids are a source of fiber and meat for the inhabitants of the Andean region of Bolivia, Argentina, and Chile. When camelids are well fed they efficiently convert the Andean flora into meat with high protein content. Vicuñas have a great capacity to produce wool to be used as a high quality fiber. However, the yield of vicuña meat production is generally low. There have been several studies concerning nutritional forage sources for camelids, resulting in improved nutrition, decreased morbidity and mortality, and intensified production systems. Soft straw is a source of tough forage with low protein content. …

The Effects Of Bacterial Inoculants On The Fermentation, Aerobic Stability And Rumen Degradability Characteristics Of Wheat Silages, Eki̇n Sucu, İsmai̇l Fi̇lya

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to determine the effects of lactic acid bacteria (LAB) inoculants on the fermentation, aerobic stability and in situ rumen degradability characteristics of wheat silages. Wheat was harvested at the early dough stage. Inoculant-1188 (Pioneer^{®}, USA) and Sil-All (Alltech, UK) were used as LAB inoculants. Inoculants were applied to silages at 1.5 x 10^6 cfu/g levels. Wheat material was ensiled in 1.5-l special anaerobic jars, equipped with a lid enabling gas release only. Three jars from each group were sampled for chemical and microbiological analysis 2, 4, 8, 15 and 50 days after ensiling. At the …

Turkish Journal of Veterinary & Animal Sciences

The present study investigated the effects of double injections of PGF_{2}\alpha at different intervals (10 vs. 14 days) on plasma progesterone levels, oestrus and lambing rates in Tuj ewes during the breeding season. Thirty clinically healthy mature ewes were assigned randomly into 2 experimental groups: 2 injections of 125 µg of Cloprostenol (a PGF_{2}\alpha analogue) at either 10 (Group I, n = 15) or 14 day (Group II, n = 15) intervals. Blood samples were collected from the jugular vein on the day of the second injection of PGF_{2}\alpha, 4 days post-injection and 16 days after insemination to determine plasma …

Effects Of Feeding Frequency On Growth, Feed Consumption, And Body Composition In Juvenile Turbot (Psetta Maxima Linnaeus, 1758) At Low Temperature, Ali̇ Türker Jan 2006

Effects Of Feeding Frequency On Growth, Feed Consumption, And Body Composition In Juvenile Turbot (Psetta Maxima Linnaeus, 1758) At Low Temperature, Ali̇ Türker

Turkish Journal of Veterinary & Animal Sciences

Juvenile turbot Psetta maxima (Linnaeus, 1758) (15.23 ± 2.99 g) were fed to satiation with a commercial extruded feed over a 60-day period. Feeding regimens were twice a day (TD), every other day (EOD), and 2-day intervals (TDI). Fish were kept in seawater (18 ppt) at 5-7.5 °C from January 21 to March 23, 2004. Feed conversion rate (FCR) and the protein efficiency ratios (PER) were within the ranges of 1.12-1.14 and 2.26-2.29, respectively. While the maximum relative growth rate (RGR), weight gain, and specific growth rate (SGR) were recorded in the TD group, they were lower in the EOD …

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 specimens were discussed at the subspecies level, comparing to the relevant literature, and it was concluded that our specimens represent the nominate form.

Testing The Randomness Of The Samples Of Body Size In A Replicated Design In Drosophila Melanogaster Populations From The Eastern Mediterranean, Ergi̇ Deni̇z Özsoy, Ali̇ Ni̇hat Bozcuk

Turkish Journal of Zoology

Strong body size correlates, wing and thorax lengths, of Drosophila melanogaster populations from the Eastern Mediterranean were measured and tested for the presence of autocorrelation, i.e. nonrandom alternation of individual measurements within a sample. The experimental design was a laboratory setup aiming at overall homogeneity in fly culture conditions, which was achieved. A t-test, first proposed by Von Neumann, was performed for the autocorrelation analysis in each population. No significant autocorrelation was detectable, indicating very low bias in the experimental design for nonrandom picking of individuals for measurements. The test is suggested for routine use in studies before any inference …

In this study, age, growth, and sex ratio of 342 golden grey mullets, which were caught in fish traps during fishing season were determined. The samples were between 7.5 and 39.5 cm in length and were between < 1 and 4 years old. The length-weight relationship for this population was calculated as W = 0.01*L^{2.93}, L_{\infinity} = 43.2 cm, K = 0.33 yr^{-1}, and t_o = -0.30 yr. The male:female ratio of the population was 1:1.87 and first maturity was at the age of one year for both sexes.

Test For Acute Toxicity Of Copper, Cadmium, And Mercury In Five Marine Species, Ermelinda Prato, Francesca Biandolino, Christian Scardicchio

Turkish Journal of Zoology

: The acute toxicity of copper (Cu), cadmium (Cd), and mercury (Hg) to the marine invertebrates Gammarus aequicauda, Corophium insidiosum, Idotea baltica, Sphaeroma serratum, and Mytilus galloprovincialis were evaluated by static bioassays and calculation of the LC_{50} (lethality concentration for 50%). Hg was more toxic to Gammarus aequicauda, Corophium insidiosum, Idotea baltica, Sphaeroma serratum, and Mytilus galloprovincialis than Cu and Cd. Cu was the least toxic of the metals tested.

Turkish Journal of Zoology

Currently, 4 species, Mesocricetus auratus, Mesocricetus raddei, Mesocricetus newtoni, and Mesocricetus brandti of the genus Mesocricetus are accepted as the valid taxa based on karyotype and morphologic features. A potential fifth species, Mesocricetus nigriculus, is under dispute and is currently listed as a subspecies of M. raddei, along with Mesocricetus raddei raddei and Mesocricetus raddei avaricus. UPGMA cluster analyses performed with biometrical measures confirm, only partially, the common separation of Mesocricetus hamsters into a Transcaucasian group with Mesocricetus newtoni, Mesocricetus brandti, and Mesocricetus auratus, and a Ciscaucasian group including the M. raddei subspecies. The status of M. nigriculus could not …

Turkish Journal of Zoology

We examined 529 specimens of Mus domesticus and Mus macedonicus from Turkey, in terms of their morphological, bacular, and phallic aspects.
