Exploring the non-genetic factors that affect reproduction traits of Saanen Goats in Indonesia

open access: yesJournal of Agriculture and Rural Development in the Tropics and Subtropics, 2023
Adjustment of trait records for different non-genetic factors increases the accuracy of genetic parameters and enables more accurate selection. This study aimed to investigate the non-genetic factors affecting reproductive traits in Saanen goats at the ...

Effects of Simulated Nitrogen Deposition and Micro-Environment on the Functional Traits of Two Rare and Endangered Fern Species in a Subtropical Forest

open access: yesPlants, 2022
Although the effects of N deposition on forest plants have been widely reported, few studies have focused on rare and endangered fern species (REFs). Information is also lacking on the effects of micro-environments on REFs. We investigated the effects of

Co-evolution of male and female reproductive traits across the Bruchidae (Coleoptera) [PDF]

open access: yes, 2008
1. Despite the obvious importance of spermatozoa to individual reproductive success a general explanation of variation in spermatozoan form and function is still lacking. In species with internal fertilization, sperm not only have to interact with the

Environmental conditions during early life accelerate the rate of senescence in a short-lived passerine bird [PDF]

open access: yes, 2015
Environmental conditions experienced in early life may shape subsequent phenotypic traits including life history. We investigated how predation risk caused by domestic cats (Felis silvestris catus) and local breeding density affected patterns of ...

Reproductive efficiency and milk yield in Sindhi breed cattle

open access: yesBrazilian Journal of Veterinary Medicine, 2020
The aim of this study was to identify the average of productive and reproductive traits in Red Sindhi females and evaluate if there is an influence of the reproductive traits on milk yield in this breed. Data related to reproductive and productive traits

Assessing risks of invasion through gamete performance: farm Atlantic salmon sperm and eggs show equivalence in function, fertility, compatibility and competitiveness to wild Atlantic salmon [PDF]

open access: yes, 2014
Adaptations at the gamete level (a) evolve quickly, (b) appear sensitive to inbreeding and outbreeding and (c) have important influences on potential to reproduce.

Effect of competitive cues on reproductive morphology and behavioral plasticity in male fruitflies [PDF]

open access: yes, 2015
Phenotypic plasticity will be favored whenever there are significant fitness benefits of responding to environmental variation. The extent and nature of the plasticity that evolves depends on the rate of environmental fluctuations and the capacity to ...

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

open access: yesActa 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.
