This research examines changes in word retrieval and naming during a developmental period in which there is a substantial increase in productive vocabulary. That increase generally occurs when children have between 50 to 150 words in productive vocabulary. We examined children's naming errors in two studies for what these errors could tell us about the emerging lexicon. The method we used for e...

Heritability and genetic correlations for honey (HP) and propolis production (PP), hygienic behavior (HB), syrup-collection rate (SCR) and percentage of mites on adult bees (PMAB) of a population of Africanized honeybees were estimated. Data from 110 queen bees over three generations were evaluated. Single and multi-trait models were analyzed by Bayesian Inference using MTGSAM. The localization...

ABSTRACT The objective was to study the productive and biological traits of young cattle Kalmyk breed its crosses. experiment conducted on 4 groups steers, 10 heads each, at OAO Shurupovskoe, Frolovsky District, Volgograd Region. experimental steers were kept in rooms separately a deep bed straw had free access walking yards with mounds. hemoglobin content numbers erythrocytes leukocytes determ...

BACKGROUND AND AIMS Plant functional traits are assumed to be adaptive. As selection acts on individuals and not on traits, interpreting the adaptive value of a trait not may be straightforward. For example, productive leaves are associated with fertile environments. However, it is not clear if productive leaves confer an advantage in these habitats, or if they are an advantage as part of a sui...

The data on 171 Murrah buffaloes sired by 49 pertaining to lifetime performance traits were collected from history cum pedigree sheets maintained at Buffalo Research Centre (BRC), Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar over a period of 20 years from 1990 to 2009. Analysis of variance done by restricted maximum likelihood method of Harvey (1990) using mixed linear re...

Four US genetic-economic indices for dairy cattle were retrofitted to illustrate differences in phenotypic response observed for retrospective selection over 2 generations for currently evaluated traits, even though producers did not have evaluations available at the time for direct selection for those traits. Differences among cows were compared based on ranking of their sires and maternal gra...
