A genome-wide linkage map for the house sparrow (Passer domesticus) provides insights into the evolutionary history of the avian genomeIngerid Hagen, Sigbjørn Lien, Anna Billing, Tore O. Elgvin, Cassandra Trier, Alina K. Niskanen, Maja Tarka, Jon Slate, Glenn-Peter Sætre & Henrik Jensen
The house sparrow is an important model species for studying physiological, ecological and evolutionary processes in wild populations. Here, we present a medium density, genome wide linkage map for house sparrow (Passer domesticus) that has aided the assembly of the house sparrow reference genome, and that will provide an important resource for ongoing mapping of genes controlling important traits in the ecology and evolution of this species. Using a custom house sparrow 10K iSelect Illumina...
Data from: Temperature does not influence functional response of amphipods consuming different trematode preyAna Born-Torrijos, Rachel A. Paterson, Gabrielle S. Van Beest, Jessica Schwelm, Tereza Vyhlídalová, Eirik H. Henriksen, Rune Knudsen, Roar Kristoffersen, Per-Arne Amundsen & Miroslava Soldánová
Direct consumption on free-living cercariae stages of trematodes by non-host organisms interferes with trematode transmission and leads to reduced infections in the next suitable hosts. Consumer functional responses provide a useful tool to examine relationships between consumption rates and ecologically relevant prey densities, whilst also accounting for abiotic factors that likely influence consumption rates. We investigated how temperature influences the consumer functional response of the amphipod Gammarus lacustris towards the cercariae of three freshwater trematodes...
The last moves: the effect of hunting and culling on the risk of disease spread from a population of reindeerAtle Mysterud, Geir Rauset, Bram Van Moorter, Roy Andersen, Olav Strand & Inger Rivrud
1. Hunting and culling are frequently used to combat infectious wildlife diseases. The aim is to markedly lower population density in order to limit disease transmission or to eradicate the host. Massive host culling can yield a trade-off when combating wildlife disease; it follows that intrusive actions may have unintended behavioural side-effects, leading to the geographic spread of disease. The manner in which such excessive hunting and culling of hosts can affect the movement and...
Oxygen consumption of juvenile brown trout, Salmo trutta, under varying thermal conditions during embryogenesisRichard Durtsche, Bror Jonsson & Larry Greenberg
Climate change is predicted to increase the future thermal conditions in northern latitudes with the potential effect of altering the metabolic scope and potential fitness of aquatic ectotherms. We experimentally tested the effect of elevated egg incubation temperature on the metabolic scope in juvenile brown trout (Salmo trutta). Brown trout cohorts from anadromous and resident crosses were raised from egg through exogenous feeding of juveniles in either natural river temperatures (cold) or elevated (+ 3...
The European eel (Anguilla anguilla) is critically endangered throughout its range. Knowledge about age distribution of future spawners (silver eels) is essential to monitor the status and contribute to the recovery of this species. Determination of age in anguillid eels is challenging, especially in eels from the northern part of the distribution area where growth is slow and age at maturation can be up to 30 years or more. Eels from the river Imsa in...
Genetic variation at the species and population levels in the Rocky Mountain ridged mussel (Gonidea angulata) – Supplementary MaterialJames Walton, Karen E. Mock, Steven Brownlee, Jon H. Mageroy, Greg Wilson & Ian Walker
Freshwater mussels in western North America are threatened by water diversions, climate change, loss of required host fish, and other factors, and have experienced marked decline in the past several decades. All four of the primary lineages (potentially species) of freshwater mussels in the western U.S. and Canada are widespread and have somewhat generalist host fish requirements. Of these lineages, perhaps the most poorly understood and of greatest conservation concern is Gonidea angulata (Rocky Mountain...
Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequencesArne Johan Jensen, Bengt Finstad, Peder Fiske, Ola Håvard Diserud & Eva Bonsak Thorstad
Consistent individual differences in behaviour has been demonstrated for many animals, but there are few studies of consequences of such repeated behaviour in the wild. We tested consistency in migration timing to and from the sea among anadromous Arctic char (Salvelinus alpinus) and brown trout (Salmo trutta), using data from a study period of about 25 years, including more than 27,000 uniquely Carlin-tagged individuals that migrated to sea for feeding in the spring and returned...
