Fine-scale population structure and asymmetrical dispersal in an obligate salt-marsh passerine, the Saltmarsh Sparrow (Ammodramus Caudacutus) [PDF]

open access: yes, 2012
Understanding the spatial scale of gene flow can yield valuable insight into the ecology of an organism and guide conservation strategies. Fine-scale genetic structure is uncommon in migratory passerines because of their high vagility and presumed high ...

Translocation effects on regional and local population viability and connectivity

open access: yesConservation Biology, EarlyView.
Abstract Translocations and reintroductions aim to improve the viability of isolated populations and promote connectivity for large carnivores. However, there is no established framework for assessing their success. We used the Eurasian lynx (Lynx lynx) in western and central Europe to assess the impact of translocations on the viability of six ...

A haplotype regression approach for genetic evaluation using sequences from the 1000 bull genomes Project

open access: yesSpanish Journal of Agricultural Research, 2018
Haplotypes from sequencing data may improve the prediction accuracy in genomic evaluations as haplotypes are in stronger linkage disequilibrium with quantitative trait loci than markers from SNP chips.

Infectivity decline of an RNA plant virus by increased mutagenesis supports the lethal defection model in vivo [PDF]

open access: yes, 2013
Lethal mutagenesis is a new antiviral therapy based on increasing the mutation rate by using mutagenic base and nucleoside analogues whose molecular mechanisms are not fully understood.

Genetic integrity of the Dark European honey bee (Apis mellifera mellifera) from protected populations: a genome-wide assessment using SNPs and mtDNA sequence data [PDF]

open access: yes, 2014
The recognition that the Dark European honey bee, Apis mellifera mellifera, is increasingly threatened in its native range has led to the establishment of conservation programmes and protected areas throughout western Europe.

TNF‑α Gene Polymorphisms as Determinants of Alloantibody Emergence in Hemophilia: A Systematic Review and Meta‐Analysis

open access: yesHaemophilia, EarlyView.
ABSTRACT Introduction Inhibitor development remains one of the most serious complications of replacement therapy in patients with hemophilia. Tumour necrosis factor‐alpha (TNF‐α) is a key pro‐inflammatory cytokine, and its genetic variants have been implicated in immune‐related conditions.

Detection of growth-related QTLs in turbot (Scophtalmus maximux) [PDF]

open access: yes, 2011
Background The turbot (Scophthalmus maximus) is a highly appreciated European aquaculture species. Growth related traits constitute the main goal of the ongoing genetic breeding programs of this species. The recent construction of a consensus linkage map

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Risk factors and genetic parameters of longevity in Spanish dairy goat breeds using a Weibull proportional hazards model

open access: yesItalian Journal of Animal Science
The aim of this study was to assess the most important risk factors that influence productive life (PL) and to estimate genetic parameters for PL using a Weibull proportional hazards model in two Spanish dairy goat breeds belonging to different ...

Porvac® Subunit Vaccine Protects Against Three Field Isolates of Classical Swine Fever Virus

open access: yesVaccines
The control of classical swine fever (CSF) in endemic areas has been attempted with modified live vaccines. However, in some regions, the implementation of imperfect vaccination programs has led to a reduction in the genetic diversity of the circulating ...
