Centrosome amplification induced by dna damage occurs during a prolonged g2 phase and involves atm
(Wiley-Blackwell, 2004-09-09)Centrosomes are the principal microtubule organising centres in somatic cells. Abnormal centrosome number is common in tumours and occurs after gamma-irradiation and in cells with mutations in DNA repair genes. To investigate ... -
Dietary n-3 polyunsaturated fatty acid supplementation alters the expression of genes involved in the control of fertility in the bovine uterine endometrium
(American Physiological Society, 2012-07-31)The potential for dietary supplementation with n-3 polyunsaturated fatty acids (n-3 PUFA) to improve reproductive efficiency in cattle has received much interest. The mechanisms by which n-3 PUFA may affect physiological ... -
Effect of short term diet restriction on gene expression in the bovine hypothalamus using next generation rna sequencing technology
(Springer Nature, 2017-11-09)Background: Negative energy balance (NEB) is an imbalance between energy intake and energy requirements for lactation and body maintenance affecting high-yielding dairy cows and is of considerable economic importance due ... -
Gamete fertility and ovule number variation in selfed reciprocal f1 hybrid triploid plants are heritable and display epigenetic parent-of-origin effects
(Wiley-Blackwell, 2013-01-31)Polyploidy and hybridization play major roles in plant evolution and reproduction. To investigate the reproductive effects of polyploidy and hybridization in Arabidopsis thaliana, we analyzed fertility of reciprocal pairs ... -
Including unsexed individuals in sex-specific growth models
(Canadian Science Publishing, 2017-04-19)Sexually dimorphic growth models are typically estimated by fitting growth curves to individuals of known sex. Yet, macroscopically ascribing sex can be difficult, particularly for immature animals. As a result, sex-specific ... -
Life history and photoperiodic responses inchondrus giganteusformaflabellatus(gigartinaceae, rhodophyta) from japan
(Informa UK Limited, 1994-08-01)The life history and photoperiodic responses of the carrageenophyte Chondrus giganteus forma flabellatus (Rhodophyta) from Japan were investigated in culture. This entity has a Polysiphonia-type life history and the formation ... -
Life history, morphology and crossability ofchondrus ocellatusformaocellatusandc. ocellatusformacrispoides(gigartinales, rhodophyta) from the north-western pacific
(Informa UK Limited, 1993-08-01)The morphology, life histories and crossability in culture are described for the marine red algae Chondrus ocellatus Holmes forma ocellatus from Japan, China and Korea and C. ocellatus f. crispoides Mikami (Gigartinaceae, ... -
Metabolic efficiency underpins performance trade-offs in growth of arabidopsis thaliana
(Springer Nature, 2014-03-28)Growth often involves a trade-off between the performance of contending tasks; metabolic plasticity can play an important role. Here we grow 97 Arabidopsis thaliana accessions in three conditions with a differing supply ... -
Size-related variation in fecundity of european eel (anguilla anguilla)
(Oxford University Press (OUP), 2012-07-12)Declining European eel ( Anguilla anguilla) recruitment has focused attention on conservation of potential spawners leaving continental waters. Fecundity of wild, seaward-migrating silver-phase eels was shown to be ... -
Speciation in red algae: members of the ceramiales as model organisms
(Oxford University Press (OUP), 2011-07-08)Red algae (Rhodophyta) are an ancient group with unusual morphological, biochemical, and life-history features including a complete absence of flagella. Although the red algae present many opportunities for studying ... -
Stronger sexual selection in warmer waters: the case of a sex role reversed pipefish
(Public Library of Science (PLoS), 2012-08-27)In order to answer broader questions about sexual selection, one needs to measure selection on a wide array of phenotypic traits, simultaneously through space and time. Nevertheless, studies that simultaneously address ... -
The influence of pre-recruitment growth on subsequent growth and age at first spawning in atlantic herring (clupea harengus l.)

Using historical data to detect temporal changes in the abundances of intertidal species on irish shores
(Cambridge University Press (CUP), 2005-11-09)An historical data set, collected in 1958 by Southward and Crisp, was used as a baseline for detecting change in the abundances of species ill the rocky intertidal of Ireland. In 2003, the abundances of each of 27 species ...
