Genetic Selection Approach for Semen Characteristics in Thai Native Grandparent Roosters (Pradu Hang Dum) Using Random Regression Test-Day Models and Selection Indices

Animals
The aim of this study was to analyze suitable genetic models and selection indices to estimate the genetic parameters and breeding values of native Thai roosters. A total of 3475 records of seven semen traits (mass movement, semen pH, semen color, volume,

The costs of extra‐pair behaviours in birds

Biological Reviews, EarlyView.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Female reproductive tract-on-a-chip for selecting sperm with ultra-low DNA fragmentation index

Microsystems & Nanoengineering
High levels of sperm DNA fragmentation index (DFI) represent a critical factor in male infertility, with detrimental effects on embryonic development and offspring well-being. However, selecting sperm with low DFI remains a tremendous challenge. Here, we

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Selection criteria in the search for a sperm donor: Behavioural traits versus physical appearance

, 2015
Despite extensive literature on female mate choice, empirical evidence on women’s mating preferences in the search for a sperm donor is scarce, even though this search, by isolating a male’s genetic impact on offspring from other factors like paternal ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Post-copulatory sexual selection and sperm phenotypes [PDF]

, 2015
Postcopulatory sexual selection has two basic components, sperm competition and cryptic female choice. In this thesis I summarize available data of the influence of postcopulatory sexual selection on sperm morhology and phenotype, focusing on both ...

Sperm competition accentuates selection on ejaculate attributes.

, 2019
4 pagesInternational audienceEjaculate attributes are important factors driving the probability of fertilizing eggs. When females mate with several males, competition between sperm to fertilize eggs should accentuate selection on ejaculate attributes. We

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency

Epilepsia, EarlyView.
Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.

Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...
