Effect of heterozygosity, ploidy and incubation temperature on post‐cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract The teleostean post‐cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early‐life environmental impacts on its meristic variation and if reduced heterozygosity challenges its development.

Integrative morphometric and molecular analyses reveal possible genetic contamination of silver catfish populations of the genus Rhamdia in Neotropical River basins

Journal of Fish Biology, EarlyView.
Abstract Rhamdia quelen, Rhamdia branneri and Rhamdia voulezi are morphologically similar species that, until recently, were considered synonymous. Although R. quelen has wide distribution in the Neotropical region, R. branneri and R. voulezi are sympatric and endemic species of the Iguaçu River basin.

A Black Phase Female in the Historical Breeding Range of Canadian Swallowtails (Lepidoptera: Papilionidae) [PDF]

, 2018
A black phase female, collected in 2000 in Isabella Co., MI, in the historical range of Papilio canadensis Rothschild and Jordan, could be a result of recent introgression by P. glaucus L. If so, black females may become widespread, though infrequent, in

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Molecular characterization of Serrasalmidae hybrid in the upper Paraná River floodplain using molecular markers

Journal of Fish Biology, EarlyView.
Abstract This study reports the molecular identification of a tambacu—a hybrid of Colossoma macropomum and Piaractus mesopotamicus—in the floodplain of the upper Paraná River using molecular markers. The PCR‐GEL method, based on the analysis of COI and TROP fragments, successfully characterized the hybrid, while PCR‐SEQ, employing RAG2 and TROP markers,

Comparative Study on Milk Production, Milk Components, Feed Intake and Efficiency Parameters of Fleckvieh (German Simmental), Brown Swiss and Fleckvieh × Red Holstein Dairy Cows

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The aim of this study was to compare milk production, milk components and feed intake of Fleckvieh, Brown Swiss and Fleckvieh × Red Holstein dairy cows kept under identical feeding and management conditions. The study examined efficiency parameters in relation to feed, energy, protein, and metabolic weight of the three breeds.

Revisiting the species problem in Northeast Pacific ribbon kelp lineages (genus Alaria): Lessons learned using whole genome data

Journal of Phycology, EarlyView.
Abstract The transition from interbreeding populations to species continues to represent difficult terrain for phylogenetic investigations. Genotyping entire genomes holds promise for enhancing insights into the process of speciation and evolutionary relationships among recently speciated taxa.
