Estimates of Genetic Parameters for Ewe Longevity and Lifetime Reproductive Performance Traits in South African Merino Sheep

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Ewe's functional longevity impacts flock profitability by reducing annual ewe replacement costs and increasing ewe outputs over the production cycle. In this context, the main objective of this study was to estimate variance components and genetic parameters of five ewe longevity indicators in South African Merino sheep.

Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

A modified indirect method for computing inbreeding coefficients

open access: yesGenetics Selection Evolution
Abstract The performance of existing methods for computing inbreeding coefficients—including tabular-based methods, Cholesky decomposition-based methods, and indirect methods—has been limited by either memory usage, pedigree depth, or average half-sib family size.

Morphofunctional effects of captivity on the microanatomy of the talus bone in a wild ungulate (Sus scrofa)

open access: yesJournal of Anatomy, EarlyView.
Our study explores the plastic changes induced by captivity on the microanatomy of the talus of wild boars, revealing denser bone with tighter trabecular networks but a lower relative maximum thickness of compact bone. These plastic adaptations can serve to detect early processes of domestication in the archaeological record.

Selection, maternal effects and inbreeding in reindeer husbandry [PDF]

open access: yes, 2003
In extensive grazing systems where several owners’ flocks are allowed to mix, selection strategies will also interact, due to gene flow between flocks. The aim of the thesis was to analyse breeding schemes in terms of genetic gain and rate of inbreeding (

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change

open access: yesJournal of Phycology, EarlyView.
Abstract Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long‐term success of kelp restoration.

Genome‐wide association study of morphometric and metabolic characteristics in European populations of the sugar kelp Saccharina latissima

open access: yesJournal of Phycology, EarlyView.
Abstract The sugar kelp Saccharina latissima is a promising candidate for sustainable aquaculture in the North Atlantic and Northeast Pacific, but genetic improvement has been hindered by a limited understanding of the genetic basis of economically important traits.

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

open access: yesJournal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.
