Genetic composition of facultatively anadromous brown trout Salmo trutta L. in a freshwater‐lake system

Ingerid J. Hagen, Rachel A. Paterson, Sten Karlsson, Ola H. Diserud et autres

Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life-history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions. This affects genetic …

The importance of mitochondrial DNA introgression for conservation

Jack A. Brand, Michael G. Bertram, Geir H. Bolstad, Tomas Brodin et autres

Human-mediated gene flow is increasingly altering the genetic composition of populations, yet conservation assessments typically focus on nuclear introgression alone. We synthesise evidence showing that mitochondrial DNA (mtDNA) introgression can have distinct consequences for performance, adaptation, and the viability of animal populations. …

Genetic Markers for Tracing Introgression of Farmed Atlantic Salmon ( Salmo salar ) in Wild Conspecifics

Ingerid J. Hagen, Kjetil Hindar, Geir H. Bolstad, Yann Czorlich et autres

Genetic introgression of domesticated plants and animals into wild populations occurs globally. Such introgression disrupts adaptive potential, reduces fitness in wild populations and threatens intraspecific genetic variation. The best-documented case of farmed introgression into wild populations is that of the Atlantic salmon …

The genetic structure of sea trout (Salmo trutta L.) in Norway

Ingerid J. Hagen, Øystein Skaala, María Quintela, Geir Olav Dahle et autres

Abstract Sea trout is the anadromous form of brown trout (Salmo trutta) and is culturally, economically, and ecologically important across its native distribution. Here, we describe the genetic structure of sea trout caught in 105 rivers from the 2600 km long Norwegian …

The Genetic Architecture of Recombination Rates is Polygenic and Differs Between the Sexes in Wild House Sparrows ( Passer domesticus )

John McAuley, Bertrand Servin, Hamish A. Burnett, Cathrine Brekke et autres

Meiotic recombination through chromosomal crossing-over is a fundamental feature of sex and an important driver of genomic diversity. It ensures proper disjunction, allows increased selection responses, and prevents mutation accumulation; however, it is also mutagenic and can break up favorable haplotypes. This …

Spatial variation in the evolutionary potential and constraints of basal metabolic rate and body mass in a wild bird

Ådne M. Nafstad, Bernt Rønning, Kenneth Aase, Thor Harald Ringsby et autres

Abstract An organism's energy budget is strongly related to resource consumption, performance, and fitness. Hence, understanding the evolution of key energetic traits, such as basal metabolic rate (BMR), in natural populations is central for understanding life‐history evolution and ecological processes. Here we …
