“…Nevertheless, in our view there is enough evidence in hand now to be confident of the main framework of the story. The critical evidence comes from investigation of three contrasting genetic componentsthe maternally inherited mitochondrial DNA (mtDNA; Vilà et al 1997Vilà et al , 1999Savolainen et al 2002;Leonard et al 2002;Pang et al 2009;Pilot et al 2010;Druzhkova et al 2013;Thalman et al 2013), the paternally inherited Y-chromosome (Bannasch et al 2005;Sacks et al 2008Sacks et al , 2013Brown et al 2011;Ding et al 2012), and the biparental autosomal genes and other components of the nuclear genome (Wayne & O'Brien 1987;Lorenzini & Fico 1995;Garcia-Moreno et al 1996;Hedrick et al 1997;Lindblad-Toh et al 2005;Gray et al 2009;vonHoldt et al 2010vonHoldt et al , 2011Vaysse et al 2011;Axelsson et al 2013;Wang et al 2013;Freedman et al 2014;Skoglund et al 2015).…”

The taxonomic identity and status of the Australian Dingo has been unsettled and controversial since its initial description in 1792. Since that time it has been referred to by various names including Canis dingo, Canis lupus dingo, Canis familiaris and Canis familiaris dingo. Of these names C. l. dingo and C. f. dingo have been most often used, but it has recently been proposed that the Australian Dingo should be once again recognized as a full species-Canis dingo. There is an urgent need to address the instability of the names referring to the Dingo because of the consequences for management and policy. Therefore, the objective of this study was to assess the morphological, genetic, ecological and biological data to determine the taxonomic relationships of the Dingo with the aim of confirming the correct scientific name. The recent proposal for Canis dingo as the most appropriate name is not sustainable under zoological nomenclature protocols nor based on the genetic and morphological evidence. Instead we proffer the name C. familiaris for all free-ranging dogs, regardless of breed and location throughout the world, including the Australian Dingo. The suggested nomenclature also provides a framework for managing free-ranging dogs including Dingoes, under Australian legislation and policy. The broad principles of nomenclature we discuss here apply to all free-roaming dogs that coexist with their hybrids, including the New Guinea Singing Dog.

“…The theoretical framework for the information content and evolution of barking in the dog involves very different assumptions, ranging from the theory that it is a non-communicative byproduct of domestication (Coppinger and Feinstein 1991), through the low-information level mobbing signal theory (Lord et al 2000), to the context-specific information source theory (Feddersen-Petersen 2000;Yin 2002;Pongra´cz et al 2010). As dogs are the oldest domesticated companions of humans (Druzhkova et al 2013), dog barking may have acquired a 'new target audience' in humans during the many 1,000 years of coexistence. A possible indirect proof of this is a series of playback experiments which showed that humans are able to correctly categorize barks according to their contexts (Pongra´cz et al 2005).…”

Comparing supervised learning methods for classifying sex, age, context and individual Mudi dogs from barking

et al. 2014

Barking is perhaps the most characteristic form of vocalization in dogs; however, very little is known about its role in the intraspecific communication of this species. Besides the obvious need for ethological research, both in the field and in the laboratory, the possible information content of barks can also be explored by computerized acoustic analyses. This study compares four different supervised learning methods (naive Bayes, classification trees, k-nearest neighbors and logistic regression) combined with three strategies for selecting variables (all variables, filter and wrapper feature subset selections) to classify Mudi dogs by sex, age, context and individual from their barks. The classification accuracy of the models obtained was estimated by means of K-fold cross-validation. Percentages of correct classifications were 85.13 % for determining sex, 80.25 % for predicting age (recodified as young, adult and old), 55.50 % for classifying contexts (seven situations) and 67.63 % for recognizing individuals (8 dogs), so the results are encouraging. The best-performing method was k-nearest neighbors following a A. Larranaga Student at the Universidad Alfonso X El Sabio, Av. Universidad, 1, 28691 Villanueva de la Canada, Madrid, Spain wrapper feature selection approach. The results for classifying contexts and recognizing individual dogs were better with this method than they were for other approaches reported in the specialized literature. This is the first time that the sex and age of domestic dogs have been predicted with the help of sound analysis. This study shows that dog barks carry ample information regarding the caller's indexical features. Our computerized analysis provides indirect proof that barks may serve as an important source of information for dogs as well.

“…Even if the length was not enough for further implication or comparisons with data of other studies (e.g. Germonpré et al 2009;Druzhkova et al 2013), it was enough for a species identification, and shows that the Beregovaya coprolite was in fact from a dog. Therefore, this ca.…”

The article describes the possibilities and limitations of ancient DNA research on organic materials that are usually not the focus of archaeogenetics, because of their low preservation potential and thus rareness in archaeological settings. These are remains from fish and birds, animal hairs, and coprolites. Several of the author's own key studies from different regions and time periods are presented.
