El objetivo principal de esta tesis doctoral ha sido evaluar el efecto de la variación ambiental sobre la reproducción de diferentes poblaciones de ciervo (Cervus elaphus) y corzo (Capreolus capreolus) situadas en el límite de su área de distribución, como son la región Mediterránea y la región Alpina. Estas poblaciones marginales pueden aportar una información muy valiosa en el contexto actual de cambio climático ya que pueden ayudar a predecir futuros cambios demográficos y de distribución de las especies. Como resultado principal, se ha observado que el incremento en la duración e intensidad de las sequías en ambientes mediterráneos y el adelantamiento del comienzo de la primavera en ambientes alpinos como consecuencia del cambio climático pueden provocar un desacople entre las principales etapas del ciclo reproductivo de ambas especies (como los partos o la formación de las cuernas) y el máximo de producción primaria. Todo esto podría afectar negativamente al éxito reproductivo de los ciervos y corzos que viven en estos ambientes.

Enterocolitica Infection

AbstractFree-living animals are an important environmental reservoir of pathogens dangerous for other animal species and humans. One of those is Yersinia (Y.) enterocolitica, the causative agent of yersiniosis - foodborne, enzootic disease, significant for public health. The purpose of the study was to identify bioserotypes and virulence markers of Y. enterocolitica strains isolated from roe deer (Capreolus capreolus) and red deer (Cervus elaphus) obtained during the 2010/2011 hunting season in north-eastern Poland. From among 48 rectal swabs obtained from 24 roe deer, two strains of Y. enterocolitica from one animal were isolated. Although both belonged to biotype 1A they were identified as different serotypes. The strain obtained from cold culture (PSB) belonged to serotype O:5, while the strain isolated from warm culture (ITC) was regarded as nonidentified (NI), what may suggest mixed infection in that animal. The presence of ystB gene, coding for YstB enterotoxin, directly related to Y. enterocolitica pathogenicity was detected in both strains using triplex PCR. The effect of the examination of 32 swabs obtained from 16 red deer was the isolation of two Y. enterocolitica strains from two different animals. Both belonged to biotype 1A with NI serotype, but were originated from different types of culture. They gave positive results in case of products of a size corresponding to the ystB gene. No amplicons corresponding to ail and ystA genes were found. Roe deer and red deer may carry and shed Y. enterocolitica, what seems to be important in aspect of an environmental reservoir of this pathogen. The Y. enterocolitica strains isolated from wild ruminants had the amplicons of the ystB gene, what suggest they can be potential source of Y. enterocolitica infection for humans

Grouping Behavior

We examined whether group size in red deer ( Cervus elaphus L., 1758) and roe deer ( Capreolus capreolus (L., 1758)) under predation risk by Iberian wolves ( Canis lupus L., 1758) is affected by the type of habitat in which the deer reside. We hypothesized that group size (i) would be larger in open than in closed habitats, since it is an antipredator response, and (ii) would vary more with habitat type in the species that had higher wolf predation rates. In the study area, wolves were the only predator of wild ungulates, with roe deer being the main target prey. We performed monthly transects along paths to observe the group size of red and roe deer. In roe deer, the mean group size was significantly higher in open than in closed habitats, serving as an antipredator response. However, in red deer, habitat type did not affect group size. The results indicate that under predation risk by wolves the habitat type influences the grouping behavior of roe deer but not red deer. Furthermore, compared with forests, heaths offer less protection from predators and species in this habitat would benefit from larger group sizes.

Monitoring of facultative avian scavengers on large mammal carcasses in Dinaric forest of SloveniaFacultative vertebrate scavengers have an important role in forest ecosystems, however, not much is known as to their use of carrion in temperate forests. Three carcasses of Red DeerCervus elaphusand European Roe DeerCapreolus capreolusfound dead or killed by Grey WolfCanis lupuswere monitored in March and April 2010 and 2011 on Menišija Plateau in northern Dinaric Mountains (central Slovenia) using photo-trapping and video surveillance. Carcasses were monitored for 26 days, during which 708 photos and 43 video recordings of scavengers were taken. In the 91% of all visits recorded, birds were the most frequent scavengers, with Common BuzzardButeo buteoas the most frequent species present at 76% of all visits. On average, Buzzards returned to carcasses twice per day, with an average visit lasting 29 min. Common Buzzards used carcasses to a significantly higher degree on days with snow cover, which was due to the more frequent visits per day and not to longer visits. Recorded antagonistic interspecific interactions suggested that Common Buzzards were the dominant species in the observed avian scavenger guild, as they displaced RavensCorvus coraxand GoshawkAccipiter gentilisfrom the carcass. However, Ravens frequently mobbed Common Buzzards while scavenging. Once an Ural OwlStrix uralensisalso visited prey remains of Grey Wolf, but feeding could not be confirmed. Observations suggested that carcasses of large mammals could be locally and temporarily an important food source for some facultative avian scavengers in Dinaric forests, especially in times when other food is scarce. Data from the two wolf kills also confirm the importance of predation by large carnivores in providing food for scavengers. Given the small amount of meat consumed, kleptoparasitism by solitary raptors did not bring significant losses to large carnivores, whereas gregarious avian scavengers like corvids can importantly affect the consumption process and consume large amount of biomass in a relatively short time.

Abstract The aim of this study was to describe the state of infection of roe deer (Capreolus capreolus) and red deer (Cervus elaphus) by Bartonella sp. in North-Western Poland through PCR detection of Bartonella 16S-23S rRNA ITS region in isolates of animal tissues, and also to describe the genetic diversity of detected Bartonella species based on molecular analysis of ITS. The multiple alignment analysis of ITS sequences was carried out, and homology matrices and phylogenetic trees were constructed. The DNA of Bartonella sp. was detected in tissues of 45.6% (36/79) C. capreolus and of 50% (15/30) C. elaphus. Products of two different sizes were detected: 317 bp, characteristic for B. schoenbuchensis, and 198 bp, characteristic for B. bovis. The obtained results suggest that roe and red deer are potential reservoirs of Bartonella sp. Most of the analysed ITS sequences was not specific for one host species. In constructed phylogenetic trees, sequences obtained from roe and red deer clustered together. These results suggest a lack of host specificity of most detected B. schoenbuchensis and B. bovis intraspecies strains

Liver Flukes

SummaryThe aim of the study was monitoring of liver flukes in wild ruminants including red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon) in selected regions of Slovak Republic. Between 2014 – 2016 we examined 782 faecal samples from selected wild ruminants using coprological techniques and serological methods (ELISA detection ofF. hepaticacoproantigens). None of the samples was positive for the presence ofFasciola hepatica, 5.89 % of faecal samples were positive forDicrocoelium dendriticum. Higher prevalence was recorded in mouflon (30.83 %), lower in red deer (1.49 %).D. dendriticuminfection was not determined in fallow deer and roe deer. The seasonal distribution of dicrocoeliosis indicated a highest prevalence in autumn. Significantly higher prevalence was recorded in fenced rearing when compared with open hunting grounds, suggesting that animal agglomeration, constant use of the same areas and possible stress are the main risk factors. Parasitological examination of livers of hunted wild ruminants revealed dicrocoeliosis in mouflon.
