The aim of this study was to describe the pattern and rates of growth of roe deer fawns up to the age of weaning. Eighteen fawns of Capreolus capreolus (Linnaeus, 1758) raised by their mothers in enclosures grew at decelerating rates after birth, with a monomolecular rather than sigmoid pattern. Bottle rearing modified profoundly the natural pattern of growth, but these fawns caught up with mother-reared fawns by weaning (about six months). There was no evidence for differential investment by the mothers in male and female offspring. Most mother-reared fawns showed an initial, near-linear phase in their first month (10/12 individuals). During this period milk provides all, or nearly all the nutrients; the rates of growth were high (145 g/day), and close to the value observed in a highly productive wild population. The decelerating rate of growth may be a consequence of allocation of resources to movement as these "hider" young become more active; and the monomolecular pattern may be commoner among ungulates than is currently realised.

The objective of this study was to evaluate the color of unpackaged and vacuum-packaged venison during storage. Color parameters L*, a* and b* were assessed in vacuum-packaged samples after 72, 144, 216, 288 and 360 h of storage, and in unpackaged samples – after 72, 144 and 216 h. The total change in color ΔE* in comparison with the color of fresh meat was determined. The results indicate that the storage of unpackaged venison has an adverse effect on color, giving it a darker, grayish hue. The most profound changes were observed after 144 and 216 h of storage. Vacuum packaging of venison minimizes color change and has a long-term stabilizing effect for up to 15 days.

Investigation of cervid nomenclature has revealed unavailable or preoccupied names still in use; unnoticed or unevaluated homonymy; unused or unnoticed names, including senior synonyms; unnoticed or misidentified types of genera; miscited authorship; unjustified emendations of original spelling; and corrections of nomenclatural errors that have been neglected in subsequent literature. The following names appearing in recent literature are affected: Pliocervinae Khomenko, Neocervinae, Gervulinae (unavailable names); Capreoiinae, Atceinae. Rangiferinae (attributable to Brookes, 1828, not to authors who changed their rank or corrected original speiling; take precedence over Odocoileinae when the taxa are combined, contrary to common practice); Alcinae (emendation due to Blyth, not Jerdon, now superseded by Alceinae, with priority over Rangiferinae - where relevant - here designated); Muntiacinae (author is Knottnerus-Meyer, 1907, not Pocock, 1923; Elaphodinae here designated a junior synonym); Megacerinae Viret (preoccupied by Megaloceridae Brookes, emended to Megalocerotinae); Blastocerus Wagner (an available name of which Blastóceras Fitzinger is an unjustified emendation, not a senior synonym of Ozoloceras; lectotype confirmed to he C'emus paludosas Desmarest, 1822); Dorcetaphus (junior synonym of Odocoileus, not a senior synonym of Blastocerus)', Mazama goitazoubira, Muntiacus feat, Pudu pudu {unjustified emendations); Ceruus japonicus Otsuka, 1967 (preoccupied, new name proposed); Ceruus elaphus montanus Botezat, 1903 (mimen nudum and preoccupied); and Pseudodama (preoccupied by Metaceruocerus),

Red deer Ceruus elaphus Linnaeus, 1758 stags from the Mesola Wood (northern Italy) are known for the very simplified structure of their antlers. An analysts was made of 180 sets of cranial appendages on 41 different individuals observed over 10 years, Considering only stags 5 years and older, the mean number of tines per antler pair was 5.36. The maximum number of tines per beam was invariably 4: the bez tine and the crown were always absent. Yearlings and subadults exhibited scarcely developed cranial appendages, with a high incidence of knobbers and spikers respectively. While the poor performance of young classes may be mainly due to malnutrition, in adult stags a genetic component may prevail over dietary factors: selective shooting, inbreeding and genetic drift could have fixed the already simple design of their antlers.

Based on previously published electrophoretic data on genetic variability in 31 roe deer Capreolus capreolus Linnaeus, 1758 populations, the proportion of loci polymorphic (P), average heterozygosity (H), and the inbreeding coefficient (FIS) were examined for relationships with the social structure displayed in the various populations. Our hypothesis was that genetic variability is lower and FIS-values are more positive in populations where males maintain a stable pattern of territories during the rutting season (forest dwelling roe deer) than in those characterized by pronounced fluctuations in population structure, both within and among seasons (field or mountain dwelling roe deer). P and H did not show differences among those two groups. FIS was significantly more positive in the 'forest' roe deer than in the more migratory 'type', but only when populations subjected to high culling rates were excluded from the analysis. Highly negative FIS-values in forest populations with high culling rates suggested that considerable perturbations of population structure may be caused by hunting. In conclusion, the 'forest' roe deer and the 'field' roe deer do not represent two distinct ecotypes with a particular genetic integrity, but rather reflect the considerable behavioural plasticity of the species.

Survival and hazard functions supply suitable information concerning changes in the population dynamics, especially in the case of species that are not subjected to artificial selection. One of such species is David’s deer (Elaphurus davidianus Milne-Edwards, 1866) that underwent a dramatic reduction in the population size in the first years of the XX century, but has been subsequently restored from 18 individuals.Population dynamics changes were studied on 1221 David’s deers kept in zoological gardens in the years 1947-2001. Survival and hazard functions were constructed for all individuals according to sex, and separately for those which died in the first year of life, i.e. 14.5% males and 8% females.The hazard function showed similar values for individuals of both sexes in the year 6, 10, 15, 17 and 18 of life. For all males the medians for mortality (hazard function) appeared similar to those for all females. Similar pattern was shown for yearlings. However, between day 40 and 323 shapes of these functions were quite different. Generally, the life span in females was found longer than in males.

Sika deer Cervus nippon Temminck, 1838 observability and flight behaviour were studied in an area with a high level of human disturbance (Tanzawa Mts, Japan). Deer observation rate was positively affected by habitat-related food conditions, while it was negatively correlated with the number of tourists in the study area. Flight frequency in April-September was lower than in October-February. It was also influenced by period of day, behaviour of investigator and deer group size. Group composition, deer activity and habitat condition had no effect on flight frequency. Thus, only 317 (48%) of the deer groups encountered were caused to flee and among them as many as 86% fled for a distance shorter than 40 m. It was concluded that deer in Tanzawa Mts learned to tolerate people, what is known for the populations which are unhunted or under low hunting pressure.

For the study 19 roebucks of the same age (1-3 years), shot in May 1960 and 1990 in Rogów, were used. During this thirty year period, many changes took place in the density of the roe deer population and in the manner of their taking, as well as in the species composition of cervids living together. The list of species of nematodes found in roe deer in this territory was enriched in 1990 with Ostertagia antipini and Spiculopteragia dagestanica, typical parasites of elk. Increase of the red deer population in the forests of Rogów did not influence the nematode fauna of the abomasum of roe deer in this hunting ground. However, the high increase of roe deer density in Rogów in 1990 (area B), as compared with 1960, significantly influenced the prevalence of infection with Trichostrongylus axei, T. capricola and Haemonchus contortus. The differences between mean intensities of infection of particular nematode species from the subfamily Ostertagiinae in 1960 and 1990 were insignificant. A distinct influence on the intensity of infection of many nematode species was exerted by the manner of taking roe deer, considerably different in area A and В (1990). In strongly exploited area A, the intensity of T. axei, T. capricola and H. contortus considerably decreased. This concerned especially the mean intensity of infection with H. contortus, which decreased in area A by forty-two times in comparison with area B.

Fifty-nine fallow deer Dama dama dama (Linnaeus, 1758) fitted with radio collars were monitored in the Blue Mountains, Otago, New Zealand, between September 1985 and February 1988 to determine home range size ant! patterns of range development. Fallow deer occupy small annual ranges, averaging 66 ha for females and 189 ha for males (90% isopleths calculated by the Harmonic Mean method). For resident animals the respective values were 50 ha and 127 ha. Bimonthly seasonal range size varied with sex, age-class and season, with different seasonal patterns for males and females. Only one adult female dispersed, and most females occupied the same core range throughout the period they were monitored. Some subadult females did move into new areas, by a process of range extension rather than a single dispersive range shift. In contrast most males monitored for more than 6 months shifted their range, but the distances between successive seasonal range centres never exceeded 2,6 km and could not be reliably distinguished from adult seasonal movements. The range stability and slow dispersal rates of fallow deer should make them easier to control than the other common introduced deer species in New Zealand, and should make it practical to have different management objectives and regimes for adjacent catchments in the Blue Mountains.

European yew (Taxus baccata L.) is a rare species, but is the focus of great interest because of the species recovery attempts and its use in medicine. The aim of this study was to determine the optimum conditions for the development of the young generation of this species. Four-year old yew seedlings were grown under artificial light reduction: 2, 8, and 30%, as well as in full light. The seedlings were then planted in natural conditions in fenced and unfenced areas. The results of six years field studies indicated that the greatest impact on survival was shown by the light conditions from the period before planting under the canopy of trees. Seedlings from the 2 and 8% of light showed the greatest mortality. The reason was the sudden change in light conditions, because at the time of planting (early spring), there was no reduction of light under deciduous trees. Almost all of the unfenced yew seedlings were grazed by deer, but yew survival in the unfenced group was surprisingly high despite the permanent grazing. This was explained by the high resistance of yew to cutting and the protection of seedlings by a dense layer of Rubus. The results indicated that yew trees require protection against animals for normal development, even if animals have not previously had contact with Taxus and that yew seedlings are very sensitive to sudden changes in light. Both conclusions can be applied in the development of natural and artificial regeneration of European yew and other endangered plants.

Climate variability greatly affects animals through direct and indirect effects. Animals with slow reproductive adaptation to ecological changes such as large mammals are likely to have evolved mechanisms to anticipate early such impacts of climate variability on the environment. One of the adaptive mechanisms between reproductive costs and benefits in mammals affects parental investment through biases in sex ratio. Deer might be likely to show an early detection of climate variability because conception takes place in early autumn, but the main raising cost in deer concerns lactation, which takes place at the end of the following spring. The aim of this paper is to assess whether there is a relationship between global indices of climate variability such as El Niño-Southern Oscillation (ENSO) and sex ratio of a captive population of deer. Results showed that there was a negative correlation (r=−0.65) between sex ratio and ENSO indices between 1996 and 2008. El Niño enhances drier conditions during the summer in the Iberia Peninsula, which in turn favours a female bias. Results also suggest that the mechanism of early detection of climate variability exerts a strong effect on female reproductive physiology because the long-term stability of food resources in our setting has not markedly reduced it.

Two types of scent marking behaviour are described in male Chinese water deer Hydropotes inerrnis Swinhoe, 1870 in their natural habitat in Jiangxi, China. Of all marking events, forehead-rubbing accounted for 13.6%, and urination with defaecation and/or pawing with the forefeet accounted for 86.4%. Urine was the most frequently used marking material. During the mating season, bucks seemed to reduce the size of each pellet group to increase marking frequency. A higher proportion of pellet groups was deposited together in the mating season than the non-mating season. Marking occurred more frequently near the borders than on the inner areas of territories.
