The effect of monoterpene concentrations in Sitka spruce (Picea sitchensis) foliage on the browsing behaviour and preferences of red deer (Cervus elaphus) was studied in a series of 18 choice trials. During each trial, individual hinds were given access to 16 saplings arranged in a symmetrical array and aspects of their feeding behaviour were recorded over 15 min. The principal measures of preference were the number of bites and the biomass removed from each tree. Prior to each trial each tree was subjected to a series of detailed morphological measurements and a subset of trees was sampled for subsequent monoterpene analysis. Multiple regression analysis showed total terpene concentration of needles to have a significant negative influence on both the number of bites and the total biomass removed from each tree. Differences in susceptibility of Sitka spruce trees to browsing are discussed in relation to the observed high intertree variation in terpene concentrations.

SynopsisThe study began in 1978 at Glenbranter Forest, Argyll. Use of habitat by red and roe deer was measured from the accumulation of pellet groups and from observations. Approximately 2000 trees less than 9 years old and 6000 older ones were monitored for damage and response.Habitats in areas dominated by heather in or close to the forest were the most occupied by both species and pole-stage crops the least. However, most dung was found on the extensive areas of recently planted ground. Roe deer were relatively more abundant than red deer in stands of 9 to 15 year-old trees.In summer, red deer ate mainly grasses and roe mainly forbs. In winter, these preferences remained, but Calluna became more important to both.Browsing on leaders was heaviest in winter and May–June. Approximately 50% of leaders on trees less than 6 years old were browsed annually. Most trees regained leaders within 12 months, many becoming multi-stemmed. Of the trees. 1% were bark-stripped per annum. In older stands the smaller trees were most damaged, in younger stands the larger trees.

AbstractIt is generally presumed that allosucking brings benefits to the allosucking infants. Nevertheless, the data supporting such a presumption are rare. The aim of the study was to determine whether allosucking has any impact on growth rates of the allosucking calves. Fifty pregnant hinds were observed between 28 May (1st day of calving) and 2 September (abrupt weaning of all calves) on a red deer farm at Vimperk, South Bohemia, the Czech Republic. Of the 50 calves born the growth curve was calculated for 39 calves. During their 1st month of life these calves were observed in 1015 sucking bouts. In 690 cases the calves sucked from maternal hinds and in 325 cases non-maternal hinds. Only 25·64% of calves sucked exclusively from maternal hinds. The prevailing type of sucking behaviour was a combination of sucking from maternal hinds and allosucking (74·36%). Calves sucking from maternal and non-maternal hinds showed 1·6-fold higher sucking frequency than did calves feeding from maternal hinds only. Our results indicate that to some extend allonursing behaviour of the hind may affect their calves’ feeding behaviour. The more non-filial calves the maternal hind nursed, the higher frequency of the sucking by their calves occurred. The groups of calves did not differ in birth weight. With increasing age, the relative body weight increased faster in calves sucking maternal hinds only than in calves sucking maternal and non-maternal hinds. This gain in body weight was not essentially influenced by the fact whether or not the calf’s maternal hind nursed non-filial or exclusively filial calves. However, at weaning (99 days), the lowest body weight occurred in allosucking calves whose maternal hinds were allonursing. The results suggest that allosucking does not mean an extra profit to the allosucker. Instead, in our subjects, allosucking was rather attributed to compensation of nutritional requirements based on a combination of various factors, such as discrete differences in body weight at birth and also later and allonursing of the maternal hind.

We studied the diet composition and diet overlap in sympatric red deer (Cervus elaphus hispanicus) and fallow deer (Dama dama) throughout a whole year in order to determine variation due to season, species, sex and age class by analysing rumen contents samples of 81 red and 69 fallow deer shot monthly during 2008–09 in Sierra de Andújar Natural Park, southern Spain. We assessed diet similarity and possible inter- and intra-specific foraging competition. We found different foraging strategies for both species and sexes during constraint periods, and several theoretical considerations of specific interactions and behaviour are discussed with respect to the Mediterranean environment. In both species an annual diet dominated by grasses was recorded, peaking in spring. Browses were an important food resource at the end of winter and at the end of summer, and fruit more in autumn and winter. Red deer ingested a higher proportion of browse than fallow deer, which consumed more acorns and for a longer time showed a better ability to compensate for nutritional constraint periods. An overall decline in diet similarity in summer and at the end of winter led us to assume that exploitative competition between red and fallow deer and even between sexes was probable. Red deer females showed low diet similarity to other deer, while there was a great diet overlap between red deer males and fallow deer females at the end of summer. Differences detected between both two species and sexes do not always support predictions deriving from specific body size and morpho-physiological characteristics, but can probably be explained as a consequence of different metabolic demands. The relationship between plant nutritional attributes and food selection according to reproductive or physiological status and seasonal demands for both sexes and species should be researched in order to perform a better assessment of deer feeding behaviour.
