Population Differentiation and Polygenic Selection in the Finnish Ayrshire Cows Selected on Genomic Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...

EFFECT OF INBREEDING ON LOIN AND FAT DEPTH IN HUNGARIAN LANDRACE PIGS [PDF]

Poljoprivreda, 2007
Pedigree and field test data - collected between 1997-2005 - were analyzed in a group of 68062 Hungarian Landrace pigs. The analysed traits were loin depth (LD), fat depth1 (FD1) and fat depth2 (FD2).

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

An integrative taxonomic characterization of extremophile fish Aphanius almiriensis (Teleostei: Cyprinodontiformes) in a hypersaline geothermal system (NW Anatolia)

Journal of Fish Biology, EarlyView.
Abstract The small killifish Aphanius almiriensis (Kottelat, Barbieri & Stoumboudi, 2007) inhabits from brackish springs to estuaries and coastal lagoons in the eastern Mediterranean basin. This study focused on the detailed characterization of Aphanius almiriensis from a hypersaline geothermal spring (Tuzla, Çanakkale, NW Anatolia), where extreme ...

Interactive effects of inbreeding and endocrine disruption on reproduction in a model laboratory fish

Evolutionary Applications, 2013
Inbreeding depression is expected to be more severe in stressful environments. However, the extent to which inbreeding affects the vulnerability of populations to environmental stressors, such as chemical exposure, remains unresolved.

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

A major QTL affects temperature sensitive adult lethality and inbreeding depression in life span in Drosophila melanogaster

BMC Evolutionary Biology, 2008
Background The study of inbreeding depression has major relevance for many disciplines, including conservation genetics and evolutionary biology. Still, the molecular genetic basis of this phenomenon remains poorly characterised, as knowledge on the ...

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

Journal 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 ...

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

Journal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.
