Analysis of tooth mark patterns on bone remains caused by wolves (Canis lupus) and domestic dogs (Canis lupus familiaris) for taxonomic identification: A scoping review focused on their value as a forensic tool.

The interaction between canids and humans is not free of conflicts. In Europe, wolves and dogs' attacks on domestic animals cause social and financial damages. The governments spend significant sums in compensation payments. Some of the allegations of wolf attacks on livestock may be false or difficult to prove. The insufficient expertise and unreliable methods used during the investigations often make it difficult to achieve a successful perpetrator identification, which leads to the stigmatization of this species and wrong paid compensations. Comparative studies of wolf and dog bite marks and tooth marks, to identify a potential aggressor agent, are very limited. In our study, 12,120 records were reviewed and only 16 of them fulfilled the search criteria set by the authors. Only one article carried out, exclusively, a comparison of wolf and dog bite mark patterns. These studies are commonly used in archaeological, paleontological and taphonomic contexts, but not in forensics. Despite the notable advances in bite mark analysis, most studies were carried out comparing bite marks from wolves and/or dogs and taxa belonging to other families. Currently, in forensic context, there is inconclusive evidence to certainly distinguish if the cause of death was created by wolves or domestic dogs using the forensic analysis of tooth/bite marks patterns from both canids (beyond any reasonable doubt). New and complementary forensic tools must be developed to differentiate between these two subspecies with a higher degree of certainty. Forensic veterinary odontology could play an important role in fulfilling this goal. The aim of the present work is to review and evaluate the studies on the identification of tooth marks on bone remains caused by two subspecies belonging to the same genus, wolves and domestic dogs

A Morphological and Morphometric Dental Analysis as a Forensic Tool to Identify the Iberian Wolf (Canis Lupus Signatus)

Depredation by the Iberian wolf (Canis lupus signatus) is currently thought to be a problem in some areas of Spain. However, there are few technically validated forensic tools available to determine the veracity of claims with a high degree of scientific confidence, which is important given that such attacks may lead to compensation. The analysis of bite marks on attacked animals could provide scientific evidence to help identify the offender. Thus, the aim of this study was to assess the morphological and morphometric characteristics of Iberian wolf dentition. This data collection would serve as a base-point for a more accurate identification of the wolves thorough their bite marks. For the first time, 36 dental variables have been studied in wolves' skulls, employing univariate and multivariate analyses. The general morphological dental characteristics of wolves are very similar in terms of their dental formula and tooth structure to other canids, like domestic dogs. Sex differentiation was evident, principally in terms of the maxillary distance between the palatal surfaces of the canine teeth (UbC) and the width of the left mandibular canine teeth (LlCWd). New morphometric reference information was obtained that can aid the forensic identification of bite marks caused by the Iberian wolf with greater confidence

Operational chain and techno-typological analysis of the prehistoric adornments of variscite from the center-south-west of the Spanish North Plateau. History of an artisan tradition

Los adornos de variscita son un tipo de artefacto empleado en distintos contextos de la Prehistoria reciente de buena parte de Europa Occidental y de forma general son interpretados como elementos de prestigio. El registro arqueológico del centro-sur-oeste de la Meseta Norte Española ofrece un caso de estudio ideal para reconstruir al completo su cadena operativa: 1) minería en Palazuelo de las Cuevas y otros lugares de la comarca de Aliste, 2) manufactura en los asentamientos de Quiruelas de Vidriales y en otros yacimientos y 3) consumo en una treintena de tumbas y poblados del Neolítico Final y el Calcolítico de las comarcas circundantes. Así, en este artículo se analizan las características tecno-tipológicas, escala y organización de la producción de adornos de variscita y sus continuidades y transformaciones con el paso del tiempo. Los resultados nos permiten hablar de una tradición artesana originada en el Neolítico Final la cual mantuvo sus rasgos tecno-tipológicos esenciales mientras crecieron la intensidad, la concentración y, probablemente, la especialización de su producción en el CalcolíticoDuring Late Prehistory adornments worked out of variscite are widely used as prestige items all over Europe. The archaeological record of centre-south-west Northern Spanish Meseta is an ideal case study to fully reconstruct the chaîné opératoire from 1. Mining at Aliste area (Palazuelo de las Cuevas and other nearby mines), 2. adornment manufacturing at the production locii of Quiruelas de Vidriales sites, 3. Adornment consumption in about 30 tombs and settlements from Late Neolithic to Copper Age in the nearby areas to the mining and manufacturing places. This paper analyses the technotypological features, scale and organisation of variscite adornment production patterns along time. Results allows to argue about a craft tradition born during the Late Neolithic that keep up its techno-tyopological features as grew up on intensity, concentration and most likely specialisation of the production during the Copper Ag

The Digestive System of the Arctocephalus australis in Comparison to the Dog as a Land-Carnivore Model

Marine mammals play a critical ecological role as both predator and prey. They are divided into three groups that share similar adaptations to their aquatic life, but that have very different origins and life patterns: sirenians, pinnipeds, cetaceans. The species object of our interest is the South American fur seal or Arctocephalus australis, a carnivore classified within the group of pinnipeds. The objective of the present study was to evaluate whether the anatomical characteristics of the Arctocephalus australis’ digestive system are similar to that of other land-carnivores or if, on the contrary, this species shows anatomical adaptations related to their life in the ocean. The study was carried out on 11 cadavers of the species Arctocephalus australis, made up of two adults and nine juveniles, by means of the anatomical dissection of their entire isolated digestive system. We demonstrate that, with several exceptions, the anatomical characteristics of the digestive system of the Arctocephalus australis are similar to those in other carnivores. Therefore, our data constitute an important contribution for clinical diagnostic and conservation purposes, for both veterinarians and biologists

Connections between postparotid terminal branches of the facial nerve: An immunohistochemistry study

It has been assumed that connections between the postparotid terminal branches of the facial nerve are purely motor. However, the nature of their fibers remains unexplored. The aim of this study is to determine whether these connections comprise motor fibers exclusively. In total 17 connections between terminal facial nerve branches were obtained from 13 different facial nerves. Choline acetyltransferase antibody (ChAT) was used to stain the fibers in the connections and determine whether or not all of them were motor. All connections contained ChAT positive and negative fibers. The average number of fibers overall was 287 (84–587) and the average proportion of positive fibers was 63% (37.7%–91.5%). In 29% of the nerves, >75% of the fibers were ChAT+ (strongly positive); in 52.94%, 50%–75% were ChAT+ (intermediately positive); and in 17.65%, <50% were ChAT+ (weakly positive). Fibers traveling inside the postparotid terminal cranial nerve VII branch connections are not exclusively motor

Group motivational intervention in overweight/obese patients in primary prevention of cardiovascular disease in the primary healthcare area

Background The global mortality caused by cardiovascular disease increases with weight. The Framingham study showed that obesity is a cardiovascular risk factor independent of other risks such as type 2 diabetes mellitus, dyslipidemia and smoking. Moreover, the main problem in the management of weight-loss is its maintenance, if it is achieved. We have designed a study to determine whether a group motivational intervention, together with current clinical practice, is more efficient than the latter alone in the treatment of overweight and obesity, for initial weight loss and essentially to achieve maintenance of the weight achieved; and, secondly, to know if this intervention is more effective for reducing cardiovascular risk factors associated with overweight and obesity. Methods This 26-month follow up multi-centre trial, will include 1200 overweight/obese patients. Random assignment of the intervention by Basic Health Areas (BHA): two geographically separate groups have been created, one of which receives group motivational intervention (group intervention), delivered by a nurse trained by an expert phsychologist, in 32 group sessions, 1 to 12 fortnightly, and 13 to 32, monthly, on top of their standard program of diet, exercise, and the other (control group), receiving the usual follow up, with regular visits every 3 months. Discussion By addressing currently unanswered questions regarding the maintenance in weight loss in obesity/overweight, upon the expected completion of participant follow-up in 2012, the IMOAP trial should document, for the first time, the benefits of a motivational intervention as a treatment tool of weight loss in a primary care setting
