To enable comparison with published bone collagen data, the domestic dog, wolf, and unidentified fur samples were adjusted to estimated bone collagen values. The Greenland dog samples (Fig. 5A) plotted with local marine mammals suggesting these formed a dominant dietary component, similar to archaeo...
However, most debates revolve around the wolf–dog comparison (the wolf being dog’s closest living relative), neglecting the fact that the dog’s canine family is much larger and shows some unique and intriguing features that may well have played a role in allowing dogs’ emergence as our ...
Dated to approximately 18,000 years ago, the question remains as to whether the pup was ‘a wolf or a dog or perhaps an animal that was ancestral to both’ (23; see also Chapter 2 of this book on the difficulties of classifying potential ancestral wolf or dog remains).This is obviously...
65. Popularity of brachycephalic (flat-faced) breeds has been increasing internationally, despite increasing scientific evidence highlighting the significant health and welfare challenges associated with this conformation, in comparison with mesocephalic (medium proportions) or dolichocephalic (long-faced...
Any dog owner knows that the bond with their dog is unique. The unparalleled loyalty and total devotion of a dog seems the stuff of true love – but is this a whimsical construction that bears little relation to reality? Through ground-breaking scientific experiments and eye-opening historical ...
NLP have already been described in Canid vocalisations (dhole:26; red wolf:22), including dogs’ howls11, barks27 and whines23, but none of these studies have directly tested what role they play in communication. We can assume that the occurrence of nonlinearities28 and other common measures...
A review of published mtDNA haplotypes identified thirteen non-Portuguese breeds with sufficient data for comparison. Comparisons between these thirteen breeds, and the four Portuguese breeds, demonstrated widespread haplotype sharing, with the greatest diversity among Asian dogs, in accordance with the ...
A direct comparison between learning based on black/white and size cues indicated marginally slower learning in the size-discrimination task (Milgram et al., 2000). Other studies have examined the dog’s use of spatially-based visual discrimination cues, such as when a reward location is ...
Despite utilisation of a large repertoire of visual communication methods from wolf-like ancestry, visual communication has been suggested to play a smaller role in dog–dog interactions than might be expected, most likely as signalling structures have been modified between breeds, so reducing the rel...
Standard TSST protocols were carefully adhered to, with particular attention given to processes that would promote study comparison and replicability [39,42,44,45]. Although protocol variations are common in some elements of the TSST, this team intentionally selected protocol options that have been fo...
