Identification of General Patterns of Sex-Biased Expression in Daphnia, a Genus with Environmental Sex Determination
Provedor de dados: 5
Autores: Molinier, Cecile; Reisser, Celine; Fields, Peter; Segard, Adeline; Galimov, Yan; Haag, Christoph R.
Daphnia reproduce by cyclic-parthenogenesis, where phases of asexual reproduction are intermitted by sexual production of diapause stages. This life cycle, together with environmental sex determination, allow the comparison of gene expression between genetically identical males and females. We investigated gene expression differences between males and females in four genotypes of Daphnia magna and compared the results with published data on sex-biased gene expression in two other Daphnia species, each representing one of the major phylogenetic clades within the genus. We found that 42% of all annotated genes showed sex-biased expression in D. magna. This proportion is similar both to estimates from other Daphnia species as well as from species with genetic...

Utilisation de critères fonctionnels (présence de spermatophore, maturation des ovaires) pour la détermination de la taille et de l'âge à maturité sexuelle des Nephrops norvegicus femelles de la région sud-Bretagne
Provedor de dados: 5
Autores: Morizur, Yvon.
The average length at which female Nephrops norvegicus attain their first maturity was determined during 1977 and 1978 by following the presence of spermatophores and development of the ovaries. During 1978, females were sexually mature at the age of 2 but in 1977 they did not mature before the age of 3. The cumulative maturity curves are sigmoid, due to an overlapping of Gaussian curves. A logistic equation was developed to calculate the percentage of mature females at each length. There is no evidence that the present fishing levels reduce the chances of a female with developing ovaries to be fertilized, since 90 to 100% of such females bear spermatophores.

Body Composition Comparisons by Age Groups in Hungarian Adults
Provedor de dados: 77
Autores: Ihász,Ferenc; Finn,Kevin J; Lepes,Josip; Halasi,Sabolc; Szabó,Péter.
The assessment of body composition provides a basis for evaluating changes in adults as they age. If the fat content is shown to be too high, intervention to reduce storage fat is warranted. The purpose of this paper is to report differences in body composition in men and women across three age groups (young, middle aged, older) to describe potential changes in both fat and muscularity. In addition, if fat storage is shown to be located in the visceral area (around the internal organs), then an addition risk to health would be evident. A total of 1564 Hungarian adults were tested for body mass index (BMI) and body composition using a multi-frequency electrical impedance device to determine percent body fat (PBF), percent muscularity (M%), and visceral fat...

Monitoreo de los niveles de testosterona y estradiol en el plasma sanguíneo de hembras de pargo palmero Lutjanus analis mantenidas bajo dos termoperíodos de acondicionamiento diferentes
Provedor de dados: 20
Autores: Castaño-Rivera, F.; Botero-Arango, J.
Two groups of adult Mutton snapper fish Lutjanus analis captured in the wild, each one of three females and four males, were kept during eight months under controlled temperature and photoperiod conditions in the lab in order to stimulate their sexual maturation which was in a state of latency because of the effects of confinement. The first group was maintained under an artificial cycle with temperature manipulation and the second under a control cycle, in which this parameter was left at natural conditions. Every two months blood samples from all females were taken for the analysis of plasma testosterone (T) and oestradiol (E2) levels, taking ovarian biopsies simultaneously to register the mean diameter of the oocytes. After six months, a significative...

Provedor de dados: 27
Autores: Cavalli, R.O.; Menschaert, G.; Lavens, P.; Sorgeloos, P.
The effects of increasing levels of dietary phospholipids (PL) on the reproductive performance, egg and larval quality, and lipid composition of females of the freshwater prawn &lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt; were investigated. Three isolipidic diets containing similar amounts of highly unsaturated fatty acids but varying levels of PL (0.8, 2.4 and 4.6%) were fed during 180 days to three groups of eight females originating from Thai ponds. No significant differences were observed for fecundity, egg size and hatchability, starved larvae size, and size, survival and tolerance to stress of 8 day-old larvae. Similarly, no major differences in the lipid composition of the midgut gland, ovaries and muscle tissue of females could be detected. Results...

Autores: Harterreiten-Souza,Érica Sevilha; Pujol-Luz,José Roberto.
Comparative morphology of the spermathecae of some species of Chrysomya Robineau-Desvoidy and Cochliomyia Townsend (Diptera, Calliphoridae). Little is known about the morphology of the chitinized structures of the spermathecae of the Calliphoridae. In this work, the spermathecae of Chrysomya albiceps Wiedemann, 1819, C. megacephala Fabricius, 1794, Cochliomyia macellaria Fabricius, 1775 and C. hominivorax Coquerel, 1858 are described and illustrated. The occurrence in one species of four spermathecae, an atypical form for blow flies, was recorded for the first time. The analysis of these structures will allow a better understanding of this group as well as provide taxonomic characters for future phylogenetic studies.

Autores: Fiorentini,Giovani; Santana,Márcia Cristina Araújo; Sampaio,Alexandre Amstalden Moraes; Reis,Ricardo Andrade; Ribeiro,Andressa Ferreira; Berchielli,Telma Teresinha.
The objective of this study was to evaluate the effect of different lipid sources on nutrient intake, performance, development and carcass characteristics of heifers raised in confinement. Twenty-one crossbreed heifers (Nellore × Santa Gertrudis × Braunvieh) received 600 g/kg forage composed of corn silage and 400 g/kg concentrate with a 58.0 g/kg fat content in the total diet. The following lipid sources were used: soybeans, protected fat (Megalac-E®) and soybean oil. The experimental design was completely randomized, with three treatments and seven replicates, and the means were compared by the Tukey test at 5%. The protected fat diet resulted in a greater intake of dry matter (8.80 kg/d) when compared with the other diets. The animals that were fed the...
