Genomics Reveals Extensive Population Structure and Undescribed Phylogenetic Relationships in the Cascade Torrent Salamander (Rhyacotriton cascadae)

Journal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim Aims of the study are to examine patterns of range‐wide genetic differentiation and population structure in a headwater obligate salamander living in a geologically rich region, to identify genetically distinct populations and areas of gene flow between them. Location Oregon and Washington in the Pacific Northwest, United States of America.

Pedigree reconstruction for cosexual species using simulated annealing: case study of oil palm (Elaeis guineensis) : P-124 [PDF]

, 2012
The approach of Fernandez and Toro (2006) to reconstruct pedigrees from molecular data of contemporaneous individuals using a simulated annealing algorithm was extended to hermaphroditic and monoecious species.

QTL linkage analysis of connected populations using ancestral marker and pedigree information [PDF]

, 2012
The common assumption in quantitative trait locus (QTL) linkage mapping studies that parents of multiple connected populations are unrelated is unrealistic for many plant breeding programs.

Using of relatedness and heritability in a Eucalyptus benthamii trial for conservation and breeding

Crop Breeding and Applied Biotechnology, 2023
We evaluated the genetic diversity, coancestry and heritability of an E. benthamii trial. The 115 individuals were genotyped (13 SSR) and had their height and diameter at breast height (dbh) measured.

Does Functionality Condition the Population Structure and Genetic Diversity of Endangered Dog Breeds under Island Territorial Isolation?

Animals, 2020
Despite the undefinition of the origins of Ca de Rater (CR) and Ca de Bestiar (CB) dogs, references to these endangered autochthonous breeds highlighted their ratting/pet and shepherding/guard skills for centuries.

Genetic Ancestry Reveals Historical Diversity of Formation Across Three Brazilian Communities of African Descent (Quilombos) in Central Brazil

American Journal of Human Biology, Volume 38, Issue 1, January 2026.
ABSTRACT Introduction Characterized as relatively isolated communities, many Brazilian quilombos were formed during the period of slavery in Brazil when enslaved persons (most of African descent) ran away or were abandoned by their enslavers. Quilombos in Central Brazil, whose settlement was more recent due to the relative isolation of the region ...

Relationship between genealogical and microsatellite information characterizing losses of genetic variability: Empirical evidence from the rare Xalda sheep breed [PDF]

, 2013
Preservation of rare genetic stocks requires continual monitoring of populations to avoid losses of genetic variability. Genetic variability can be described using genealogical and molecular parameters characterizing variation in allelic frequencies over

Inbreeding, Coancestry, and Founding Clones of Sweet Cherries from North America [PDF]

Journal of the American Society for Horticultural Science, 2004
Inbreeding and coancestry coefficients were calculated for 66 sweet cherry (Prunus avium L.) selections released from four breeding programs in North America (HRIO, Vineland, Ont., IAREC, Prosser, Wash., NYSAES, Geneva, N.Y., and PARC, Summerland, B.C.).
