Management of genetic diversity in small farm animal populations*

Animal, 2011
Many local breeds of farm animals have small populations and, consequently, are highly endangered. The correct genetic management of such populations is crucial for their survival.

Paternity of Western Gray Whales Feeding Off Sakhalin Island, Russia

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT While understanding mating systems can provide critical insight into a population's long‐term persistence and resilience, such information remains limited for most baleen whales. However, extensive research on the western gray whales that feed off Sakhalin Island, Russia, led to the collection of biopsy samples from 75% of the 207 whales photo‐

Effect of non-random mating on genomic and BLUP selection schemes

Genetics Selection Evolution, 2012
Background The risk of long-term unequal contribution of mating pairs to the gene pool is that deleterious recessive genes can be expressed. Such consequences could be alleviated by appropriately designing and optimizing breeding schemes i.e.

Pleistocene Divergence and Long‐Term Population Decline in Three Endemic Euphorbia Species of High Conservation Concern From the South‐Western Alps and the Mountains of Corsica and Sardinia

Diversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Understanding the evolutionary history and demographic dynamics of narrow‐ranged endemics is essential for predicting their future under climate change. We investigated the origins, population trajectories, and conservation outlook of three endemic spurges (Euphorbia gayi, E. valliniana, E. variabilis) restricted to the south‐western Alps,

Aplicación práctica de estrategias de manejo óptimo en programas de conservación: un método de selección de apareamientos [PDF]

, 2001
The maintenance of genetic diversity is, from a genetic point of view, a key objective of conservation programmes. The selection of individuals contributing offspring and the decision of the mating scheme are the steps on which managers can control ...

A case study of Eucalyptus globulus fingerprinting [PDF]

, 2011
• Introduction Tree genetic improvement programs usually lack, in general, pedigree information. Since molecular markers can be used to estimate the level of genetic similarity between individuals, we genotyped a sample of a Portuguese Eucalyptus ...

Detecting linkage between a trait and a marker in a random mating population without pedigree record. [PDF]

PLoS ONE, 2009
Modern linkage-based approaches employing extended pedigrees are becoming powerful tools for localizing complex quantitative trait loci. For these linkage mapping methods, it is necessary to reconstruct extended pedigrees which include living individuals,

Reproduction partially compensates for human‐caused mortality in a cooperative breeder

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Reproductive output can vary widely among mammalian species. There are many drivers that affect reproductive output including evolutionary, environmental, population, social, and individual traits. Although several factors, including human‐caused mortality, can affect reproductive output, we generally have a poor understanding of how such ...

Inbreeding and coancestry trends in Nordic Holstein

, 2022
Increased rates of inbreeding have been observed in several Holstein populations across the world since genomic selection (GS) was implemented into the breeding programs. The objective of this study was to test whether this is also the case in the Nordic Holstein population using pedigree data.
