Effect of rosette size, clonality and spatial distribution on the reproduction of Vriesea carinata (Bromeliaceae) in the Atlantic Forest of Paraná, southern Brazil

Acta Botânica Brasílica, 2016
Plant size and clonality are important traits for explaining the reproductive effort of clonal plants. Larger plants can invest more resources into reproduction, and clonality is known to increase reproductive effort.

Effects of selection for honey bee worker reproduction on foraging traits.

PLoS Biology, 2008
The "reproductive ground plan" hypothesis (RGPH) proposes that reproductive division of labour in social insects had its antecedents in the ancient gene regulatory networks that evolved to regulate the foraging and reproductive phases of their solitary ...

Relation of Production Traits and Reproduction Traits in Swine

Journal of Animal Science and Technology, 2007
In order to investigate the relation of production traits and reproduction traits the data from Gyungnam heugdon(Berkshire) were analyzed. Pearson correlation coefficients of the reproductive traits including days to first farrowing, days to first breeding and no. of breeding for first litter with back fat thickness were ranged -.24 to -.26.

Reproductive traits and economic aspects on dairy cattle. [PDF]

Anim Reprod
Abstract This study aimed to characterize the reproductive parameters and economic indicators of dairy farms. Data were from technical assistance of the Programa de Desenvolvimento em Pecuária Leiteira (PDPL-UFV) including 26 farms, from September 2022 to August 2023, comprising an entire production cycle.

Estimation of genetic parameters of pig reproductive traits

Frontiers in Veterinary Science, 2023
IntroductionIn this study, we aimed to estimate the genetic parameters of the reproductive traits in three popular commercial pig breeds: Duroc, Landrace, and Yorkshire. Additionally, we evaluated the factors that influence these traits.MethodWe collected data from a large number of litters, including 1,887 Duroc, 21,787 Landrace, and 74,796 Yorkshire ...

Estimation of genetic parameters and genetic trends for growth, reproductive, and survival traits of Bonga sheep using multi-variate animal model.

PLoS ONE
The community-based breeding program was introduced to enhance the productivity of Bonga sheep. Data evaluating animals' potential regarding key traits was gathered from 2009-2021.

Complex Reproductive Traits and Whole-Organism Performance [PDF]

Integrative and Comparative Biology, 2017
Arnold's 1983 path-analytic paradigm, considering "morphology, performance, and fitness," has been elaborated in several ways. For example, current versions recognize the level of "behavior" (including aspects of motivation) as a filter between performance abilities (only measurable if motivation is maximal) and fitness components.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Genetic analysis for reproductive and longevity traits in Landlly sows

Indian Journal of Animal Sciences
The rate of reproduction and lifetime productivity of the animals determine the success of a herd. As these features significantly impact sow productivity, welfare, and profitability, there is considerable interest in global swine breeding programmes to
