Hunden och människan har samexisterat i många tusen år, något som alla vänner till tamhunden i dag kan vara tacksamma över. Detta dels för att denna samvaro lett till att vi i dag har ett stort antal olika typer av hundar, formade av människan och dennes skiftande behov. Något annat som detta fört med sig är en stor praktisk kunskap...
There are nearly 400 modern domestic dog breeds with a unique histories and genetic profiles. To track the genetic signatures of breed development, we have assembled the most diverse dataset of dog breeds, reflecting their extensive phenotypic variation and heritage. Combining genetic distance, migration, and genome-wide haplotype sharing...
Dogs were the first domestic animal, but little is known about their population history and to what extent it was linked to humans. We sequenced 27 ancient dog genomes and found that all dogs share a common ancestry distinct from present-day wolves, with limited gene flow from wolves since domestication, but substantial dog-to-wolf gene flow. By...
Enligt svensk djurskyddslagstiftning ska djur ges möjlighet att bete sig naturligt, och permanenta rastgårdar ska vara berikade. Berikning innebär att tillföra eller förändra något i hundens liv och miljö som ökar deras välfärd genom att stimulera naturliga beteenden.Detta examensarbete har som resultat av litteraturstudier skrivits med förhoppning...
Abstract: Competitions involving sled dogs are rapidly growing and body temperature assessment could represent a prompt and non-invasive method of screening for potential pathological conditions during or after activity. The aim of this clinical study was to evaluate if thermography is able to monitor the pre- and post-competition ocular and...
Domestication is a process in which species are selected to live in human-controlled environments (Price 2002). The evolutionary trajectories of numerous animal and plant species has dramatically impacted by domestication, and the process thus provides an ideal framework for studying evolutionary responses to selection (Driscoll et al. 2009). In...
Body size is correlated with many critical behavioral and developmental patterns in carnivores, including domestic dogs. The body masses and bite forces of archaeological dog remains from Siberia and the Russian Far East were estimated to make inferences regarding their behaviors and capacitis. The dogs date from ~10,000e100 cal. BP and derive from...
Excavations on the Zhokhov Island yielded a small but meaningful collection of Early Holocene canine faunal remains (MNI = 13). To clarify the morphological characteristics of the Zhokhov dogs' skulls, they were compared to the modern skulls of the Eastern Siberian wolves. This analysis shows, that around 9000 years ago a fully formed, as a...
Per-Erik var en av de bästa genetikerna och varnade tidigt för riskerna med den pågående kraftiga inaveln och förlusten av genetisk variation som skedde inom hundavel. Han var SKK sakkunniga genetiker och ledamot i SKK Avelskommite. Han var även den som tog fram programmet Lathunden som både jag själv och många andra haft nytta av när vi skapat...
Although sled dogs are one of the most specialized groups of dogs, their origin and evolution has received much less attention than many other dog groups. We applied a genomic approach to investigate their spatiotemporal emergence by sequencing the genomes of 10 modern Greenland sled dogs, an ~9500-year-old Siberian dog associated with...
