hypoderma actaeon an emerging myiasis in roe deer capreolus capreolus
Medical and Veterinary Entomology, 2017Co-Authors: Rosario Panadero, Gerardo Pajares, F Markina, Ana Perezcreo, Alberto Prieto, P Diaz, Pablo Diezbanos, Germán Varas, C. Lopez, Patrocinio MorrondoAbstract:Subcutaneous larvae of Hypoderma spp. (Diptera: Oestridae) were detected in the dorsal region in 10 roe deer, capreolus capreolus (Artiodactyla: Cervidae), hunted in central Spain between January and March 2016. All larvae were found in the inner side of the hide during the skinning of the animals. The study of the morphological features of eight larvae of different stages collected from two animals allowed the identification of Hypoderma actaeon Brauer. The small size (4-5 mm) of some of the first instars suggests that the internal lifecycle of H. actaeon may be exclusively subcutaneous. This is the first confirmation of H. actaeon in roe deer; however, further studies to assess the spread of the parasite and to follow the evolution of this myiasis in roe deer are needed.

Bronchopulmonary helminths of roe deer (capreolus capreolus) in the northwest of Spain.
Veterinary parasitology, 2001Co-Authors: Rosario Panadero, E.b Carrillo, Ceferino López, N. Diez-baños, Pablo Díez-baños, M.p. MorrondoAbstract:From 1993 to 1995, 148 hunter killed roe deer (capreolus capreolus L.) from game reserves in Lugo (northwestern Spain) were examined for lungworm infection. The overall prevalence of infection was high (66.2%). Infections were comprised to two species, Varestrongylus capreoli and Dictyocaulus noerneri with a prevalence of 62.0 and 18.2%, respectively. Significant differences in the prevalence and larval burdens in lungs and faecal samples were observed between different locations. The highest overall prevalence of lungworm infection was observed in the large reserve at Ancares (78%) in comparison to that in smaller reserves (61.7%). Considering that the species recorded in this study are highly host-specific, it is unlikely that roe deer represent a significant reservoir of lungworm transmissible to domestic ruminants in northwestern Spain.

Barking in roe deer ( capreolus capreolus ): seasonal trends and possibile functions
Hystrix-italian Journal of Mammalogy, 2002Co-Authors: Iva Rossi, Lorenza Mauri, Simona Laficara, Marco ApollonioAbstract:We studied barking behaviour of roe deer, capreolus capreolus, in an area when wolves actively prey on this species, to determine the possible functions of this signal. Our data showed that males barked more frequently than females and that males barked more often during the territorial pe- riod than outside it. Undisturbed deer that barked spontaneously, before the arrival of the observer, were significantly more likely to be male than female, while both males and females showed the same likelihood to bark in response to the presence of a human observer. When barking occurs as a result of disturbance, it may act as a "pursuit-deterrent signal" rather than to warn conspecifics of potential danger. We suggest that counterbarking also acts as a pursuit-deterrent call, since audibility is rein- forced by duetting, and signals to the predator that it has been detected by the pair.

Alternative use of space strategies of female roe deer (capreolus capreolus) in a mountainous habitat
Italian Journal of Zoology, 2001Co-Authors: Paolo Lamberti, Lorenza Mauri, Iva Rossi, Marco ApollonioAbstract:Abstract The spacing behaviour of ten roe deer (capreolus capreolus) females was studied from March 1997 until February 1998 in the Casentinesi Forest National Park, Italy. The study area is mountainous with a high percentage of forest cover (95%). Mean temperature was 8° C and snowfall occurred in autumn and winter. Data were collected with radio‐tracking techniques and annual, bimonthly and monthly home ranges were analysed. The results indicated two different spacing behaviours: stationary and roaming. Roaming females had larger home ranges than stationary ones. Only during the birth period, in May‐June, were home ranges similar for both groups of females, while the winter period showed great differences. Habitat quality and social factors seemed to influence the ranging behaviour of females in this mountainous habitat in the course of the year.

Genetic variability of roe deer capreolus capreolus in Italy: electrophoretic survey on populations of different origin
Acta Theriologica, 1993Co-Authors: Rita Lorenzini, Marco Apollonio, Marianna Patalano, Vito MazzaroneAbstract:Lorenzini R., Patalano M., Apollonio M. and Mazzarone V. 1993. Genetic variability of roe deer capreolus capreolus in Italy: electrophoretic survey on populations of different origin. [In: Ecological genetics in mammals. G. B. Hartl and J. Markowski, eds]. Acta theriol. 38, Suppl. 2: 141 - 151. In order to investigate genetic variability and differentiation of roe deer capreolus capreolus (Linnaeus, 1758) in Italy, four populations were examined for polymorphism at thirty-two gene loci by means of vertical polyacrylamide gel electrophoresis. Mean values of polymorphism (mean P = 15.6%, SD 4.4%) and expected average heterozygosity (mean He = 4.7%, SD 1.9%) were comparable to those reported previously for roe deer populations of Central Europe. Moreover, the results confirmed that roe deer is one of the genetically most variable deer species yet studied. Nei's standard genetic distances (mean D = 0.008, SD 0.004) were consistent with the values generally obtained at the level of local populations in deer species. Estimates of relative genetic differentiation showed that 11.5% of the total diversity can be assigned to genetic divergence among populations. Differences in levels of genetic variation among the Italian populations studied are discussed with respect to their respective demographic origin and historical background. The implications of our data for the management of roe deer in Italy are outlined.

Presumptive primary central nervous system T cell lymphoma in a deer (capreolus capreolus).
Research in veterinary science, 2012Co-Authors: Sven Kleinschmidt, Martin Peters, Peter WohlseinAbstract:This report describes the morphological and immunohistochemical findings in an approximately 7-year old wild European roe deer (capreolus capreolus) with an infiltrative primary central nervous system T cell lymphoma. The roebuck had lost its timidity and was shot by a hunter. It was submitted for necropsy to exclude rabies. Gross examination revealed besides a verminous pneumonia no abnormal findings. Histologically, there was a highly cellular, not well demarcated, unencapsulated, and infiltrative neoplasm within basal parts of the brain. Tumour cells were round, up to 15 μm in diameter and loosely arranged in sheets with a multifocally predominant perivascular infiltration. Immunohistochemically, tumour cells were positive for CD3 antigen. Whilst secondary lymphomas of the central nervous system emerge by metastatic seeding of tumour cells, primary lymphomas originate within the neuroparenchyma. This is the first report of a primary central nervous system lymphoma in an European roe deer.

Central Nervous System Neuroblastoma in a Wild Deer (capreolus capreolus)
Journal of comparative pathology, 2011Co-Authors: Sven Kleinschmidt, Martin Peters, Peter WohlseinAbstract:This report describes a central nervous system (CNS) neuroblastoma in a wild deer (capreolus capreolus) of approximate age 10 years. The doe was found in a barn with a fractured right forelimb and was shot. The animal was submitted for post-mortem examination in order to exclude rabies. The tumour was located in the midline of the mesencephalon with replacement of thalamus and parts of the hypothalamus and infiltration into the adjacent neuroparenchyma and the right lateral and third ventricles. Microscopically, the neoplastic cells were arranged in sheets and nests forming Homer-Wright- and pseudorosettes. Immunohistochemically, the tumour cells expressed neuron-specific enolase, synaptophysin, doublecortin and neurofilament. This is the first report of an infiltrative CNS neuroblastoma in a wild deer.

Zur Frage der Kronenzementbildung an den Backenzähnen des Rehes (capreolus capreolus L.)
Zeitschrift für Jagdwissenschaft, 1992Co-Authors: Horst Kierdorf, Uwe KierdorfAbstract:We studied whether the premolars and molars of roe deer are covered by coronal cementum. Scanning electron microscopic inspection of surface enamel in freshly erupted, erupting and preeruptive teeth produced no evidence of coronal cementogenesis. This negative result was corroborated by light microscopic observations, revealing that in the lacteal premolars studied, the enamel organ was not completely reduced preeruptively. Therefore, a direct contact between cells of the dental follicle and the enamel surface, a necessary prerequisite for coronal cementogenesis, normally did not occur in roe deer. Descriptions of coronal cementum in cheek teeth of various cervid species can hypothetically be attributed to misidentification of dental calculus or may point to species-specific differences with respect to this character. An Backenzähnen des Rehes ( capreolus capreolus ) wurde untersucht, ob eine Bildung von Kronenzement stattfindet. Die rasterelektronenmikroskopische Inspektion der Schmelzoberflächen frisch hochgewachsener, erst teilweise eruptierter und kurz vor dem Durchbruch stehender Zähne erbrachte keinen Hinweis auf eine Kronenzementauflagerung. Lichtmikroskopisch konnte nachgewiesen werden, daß das Schmelzorgan von laktealen Rehprämolaren präeruptiv nicht vollständig reduziert wird und eine Kronenzemententwicklung daher normalerweise unterbleibt. Die in der Literatur enthaltenen Hinweise auf eine Kronenzementbildung an Backenzähnen verschiedener Cervidenarten könnten möglicherweise auf eine Fehlinterpretation von Zahnsteinablagerungen zurückzuführen sein oder auf artliche Unterschiede hinsichtlich der Ausbildung dieses Merkmales hindeuten. On s'est interrogé sur le fait de savoir s'il y a formation de cément au niveau de la couronne des molaires chez le Chevreuil ( capreolus capreolus ). L'examen au microscope électronique de la surface d'émail de dents à peine formées avec éruption partielle et peu avant qu'elles ne percent n'apporta aucune indication quant à un dépôt éventuel de cément. Par observation microscopique fine on put observer que le dépôt d'émail n'était pas complètement nul avant éruption des prémolaires de lait et qu'en conséquence le développement de cément au niveau de la couronne n'avait normalement pas lieu. Les indications que l'on trouve dans la littérature au sujet de la formation de cément sur les molaires d'autres espèces de Cervidés pourraient se ramener à une interprétation erronée de dépôts dentaires ou bien se rapporter à des différences spécifiques relatives à la formation de ce caractère.
