ABSTRACT: Reproductive effi ciency is of economic importance in commercial beef cattle production, since failure to achieve pregnancy reduces the number of calves marketed. Identifi cation of genetic markers with predictive merit for reproductive success would facilitate early selection of females and avoid ineffi ciencies associated with sub-fertile cows. To identify regions of the genome harb...

Female reproductive decline is one of the first aging phenotypes in humans, manifested in increasing rates of infertility, miscarriage, and birth defects in children of mothers over 35. Recently, Caenorhabditis elegans (C. elegans) has been developed as a model to study reproductive aging, and several studies have advanced our knowledge of reproductive aging regulation in this organism. In this...
