Estimating population size is particularly difficult for animal species living in concealing habitats with dense vegetation. This is the case for roe deer as for many other ungulates. Our objective was to develop a non–invasive genetic capture–mark–recapture approach based on roe deer faeces collected along transects. In a pilot study, we collected 1,790 roe deer faeces during five sampling days in a forested study area in south western Germany. We extracted DNA from 410 of these samples and carried out microsatellite analysis using seven dinucleotide markers. The analyses resulted in 328 useable consensus genotypes which were assigned to 174 individuals. The population size estimated using a Bayesian approach was 94 (82–111) male and 136 (121–156) female roe deer. Our study shows that non–invasive genetic methods are a valuable management tool for roe deer.

Hunting Statistics

Population trends, numbers of harvested adult females and harvest rates of red deer (Cervus elaphus) in Switzerland and in the canton of St. Gallen were analysed using freely accessible data from federal and regional hunting statistics. We did the same analyses with data from chamois (Rupicapra rupicapra) in Switzerland and in the cantons of Berne and St. Gallen. Data from roe deer (Capreolus capreolus) were analysed for Switzerland and the cantons of Solothurn and Vaud. The results show that the new Swiss hunting and forest laws have not had any effect on population size of red deer, chamois and roe deer yet. Regulative effects, however, could be shown locally for the red deer in the canton of St. Gallen and for the chamois in the cantons of Berne and St. Gallen. There is evidence that the present hunting statistics represent only an incomplete base for comprehensive harvest planning according to the law.

This article analyses data on the reported and captured populations of red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon) in the Czech Republic during the years 2002–2006. Breeding and hunting plans collected by the State Hunting Authority have been summarized. The analyzed game population size (APS) for each individual territory, using the reverse calculation method, was compared to the counted population size (CPS) of each species. Next, the ratios between the specified population size (SPS) and the CPS were compared; and also the ratios of CPS and actual hunting bag were compared for individual years in the specified periods. Many errors in hunting management policy were found in all analyses regarding red deer. In many cases the APS, using the reverse calculation method, was several-times higher than the CPS. Also a large difference between SPS and CPS was very common. Similar results were also found in the analyses of fallow deer and mouflon populations, where the management policy was very similar to that of red deer. Evaluation of the roe deer management policy showed better results. Despite the fact that the APS was higher than the CPS, it was never several-times higher. Even in SPS and CPS ratios no extreme outcomes were found. From the official processed data it is evident that hunting association plans for game breeding and hunting indicate many significant problems, where the smallest problem is with roe deer and the biggest problem is with red deer.

Geographic Expansion

Cephenemyia stimulator is a Palearctic species developing in the nasal cavity and pharynx of roe deer (Capreolus capreolus). It is widely spread in the range of distribution of this ungulate in Europe. Since the first report of C. stimulator in Spain in 2001, a rapid geographic expansion has been observed, first in the north of the country, with high prevalence and intensities of infestation that caused some mortal cases, and, lately, also in Extremadura and Andalucía, the southernmost populations of European roe deer. These observations suggest an adaptation of this parasite to different ecosystems of the Iberian Peninsula. Almost simultaneously, C. stimulator is also expanding its range to northern Europe, with the first cases being reported in Sweden. Thus, Cephenemyia stimulator may be an example of a parasite currently displaying distributional changes along its southernmost and northernmost range margins. Thus, it is of the utmost importance to unravel all the epidemiological and clinical aspects of this myiasis, as well as implementing surveillance measures including reliable and non-invasive diagnostic techniques to monitor its expansion and adaptation to different ecosystems and/or hosts and to reduce the negative impact on roe deer populations.

Shoulder Blade

In illegal hunting it is often possible only on the basis of morphological characteristics to determine the animal species. By the method of comparison there was performed the forensic analysis of roe deer and sheep osteological features. For the purpose of investigating the shoulder blade (Scapula) and shoulder bone (Humerus) comparative characteristics, there were used 6 shoulder blades and 6 shoulder bones of roe deer and 8 shoulder blades and 8 shoulder bones of sheep. After the skin, muscles, arterial, venous and lymphatic vessels as well as nerves were removed from the bones, they were thermally treated in an autoclave. Subsequently, the bones were placed in 3% solutioin of hydrogen peroxide (H2O2) for bleaching and degreasing. Then they were air dried and then photographed. Shoulder blade (Scapula) is a bone plate (Ossa plana) roughly triangular in shape. Scapular spine (Spina scapulae) is much more prominent in roe deer with acromion blade in the form of spike, while in sheep it is shorter and ends with acrimion at a right angle. Shoulder blade cup (Cavitas glenoidalis) in roe deer is round in shape, and in sheep it is oval. Tuberculum supraglenoidale and Processus coracoideus in sheep are more and in roe deer less developed. Shoulder bone (Humerus) in roe deer is relatively long, slender bone with proximal convexity turned cranially in regard to the same bone in sheep, which is stronger and heavier. Tuberculum majus in roe deer is less developed, and in sheep it is in a form of solid bone protuberance. Tuberculum minus and Tuberositas deltoidea in sheep are more developed than in roe deer. At medial condyle (Condylus medialis) in sheep there is shallow and wide groove, while in roe deer it is deeper and narrower. On the basis of morphological differences of roe deer and sheep bones, it can be determined with certainty which animal spesies they belong to.
