Despite this, lower male adult survival has been documented in several roe deer populations (see Gaillard et al. Assessing Fifty Years of General Health Surveillance of Roe Deer in Switzerland: A Retrospective Analysis of Necropsy Reports. [27] In Stavropol and Dnepropetrovsk regions of Ukraine most of the roe are Siberian. Roe deer population growth rates were lower in the municipalities with lynx and harsh climatic conditions than in municipalities with mild climatic conditions and/or without lynx. 1995, Aanes and Andersen 1996, Jarnemo et al. 2005, Mysterud and Østbye 2006, Melis et al. In this paper we estimated annual cause‐specific mortality rates of roe deer according to sex and age class in south‐eastern Norway (1995–2005) along a gradient in roe deer abundance. The encounter history of an individual started in May of the year of capture (coded as ‘censored' until month of capture, according to Pollock's staggered entry design; Pollock et al. Two main specialists did not recognise these taxa and considered the species to be without subspecies in 2001. Hidden among the tall grass, a young roe deer lies perfectly still. [17] While it may not have the same speed, it is extremely powerful. Roe deer is a species that is generally found in European countries. However, during winter capture we felt comfortable in separating yearlings (20–23 months of age at this time) from adults based on a range of morphological criteria including size, general shape, tooth wear, antler development, absence of following fawns, appearance of nipples. This type of index has been previously used for roe deer in Norway (Herfindal et al. 2004), but due to their generalist and opportunistic feeding behavior, they have been observed to specialize only when roe deer occur at high abundance and the higher encounter probability makes prey switching behavior profitable (Panzacchi et al. 2012) found that, after recolonisation of the study area by lynx, prime age roe deer survival was almost 20% lower than in absence of large predators (0.61 against 0.79). 1998a, Andersen and Linnell 2000, Cobben et al. The role of predation in the neonatal mortality of temperate ungulates, Scandlynx: a vision for coordinated lynx research in Scandinavia, Recovery of Eurasian lynx in Europe: what part has reintroduction played, Applying Cox regression to competing risks. A mule deer female usually gives birth to one fawn in her first pregnancy. F1 hybrid males may be sterile, but backcrosses with the females is possible. By comparison, an average adult man in Britain is 1.77m high and weighs 79kg.Roe deer vary in coat colour throughout the year, being most distinguishable in the summer when their coats are bright rusty red. 2007). Deer stalking in Scotland is thought to be worth more than £100 million annually to the economy. 2008). Therefore, while we acknowledge how crucial the studies conducted in simplified model environments have been for advancing our understanding of roe deer demographics (Gaillard et al. 1b). The southern portion of the study area includes patches of deciduous forest, represented mainly by birch Betula spp. (1998a) showed that populations of large herbivores most often have a high and stable adult survival, while the survival of juveniles is generally lower and more variable in time, depending on several density‐dependent and density‐independent factors. The annual mortality rate due to foxes was over 26%. As survival rates might vary greatly and might strongly contribute to variation in population growth rate in such environments (Nilsen et al. [31], When alarmed it will bark a sound much like a dog and flash out its white rump patch. How roe deer respond to hunters as a predator have rarely been investigated (Benhaiem et al. [1], Roe deer are most closely related to the water deer, and, counter-intuitively, the three species in this group, called the Capreolini, are most closely related to moose and reindeer. 2009), we feel that it is important to increasingly supplement these studies with others conducted under more complex conditions if we are to provide data relevant for management and conservation. [47], The polygamous roe deer males clash over territory in early summer and mate in early autumn. When the story was adapted into the animated feature film Bambi (1942), by the Walt Disney Studios, Bambi was changed to a mule deer, and accordingly, the setting was changed to a North American wilderness. 1993). 2012). Threats in the wild are few, as their natural predators, the wolf and the lynx, are now extinct in Britain. These changes made Bambi a deer species more familiar to mainstream US viewers. These are mainly from islands or fenced areas where bottom‐up effects dominate (e.g., red deer [Cervus elaphus] on the island of Rum, Coulson et al. [24][25] In 2008 the IUCN recognised three infraspecific taxa: the nominate and the subspecies garganta and italicus. The roe deer capture was conducted by experienced people who had frequent opportunities to calibrate their classification from capture of known age animals and from watching the animals at the feeding sites. [citation needed] In Wales, they are the least common, but they are reasonably well established in Powys and Monmouthshire. [25][28] Hybrids are much larger than normal and a cesarean section was sometimes needed to birth the fawns, becoming larger than their mothers at the age of 4-5 months. 2012), Tredozio (Focardi et al. As of 2016 there are some 110,000 deer in the country. [31] Populations from Urals and northern Kazakhstan are larger on average growing to 145 cm (4.8 ft) in length and 85 cm (2.8 ft) at shoulder height, with body weights of up to 60 kg (130 lb), with the deer populations becoming smaller again further east in the Transbaikal, Amur Oblast, and Primorsky Krai regions. While the recovery of the species is welcome, the absence of large carnivores in the UK means red deer have no natural predators. The inverse density‐dependence in the risk of lynx predation on roe deer has been previously described by Jędrzejewska and Jędrzejewski (1998) in the multipredator system of Białowieża Primeval Forest (Poland). This has been clearly shown in the same study area by Nilsen et al. Radio‐telemetry records were converted into monthly encounter histories with staggered entry (White and Burnham 1999) for all the 330 radio‐marked animals. In our study, both human hunting and lynx predation are amongst the most important agents of mortality and therefore our estimates of annual adult survival were lower. Despite the ongoing recovery of large carnivores in Europe and North America, few European studies on ungulate mortality are available from areas where both large carnivores and human hunters are present. In winter, their coats turn a dull, slate grey colour.Both sexes have a prominent white rump and no tail. 2). Roe deer were captured in winter at artificial feeding sites using box traps, drop nets or canon nets. [49], The roe deer population shows irruptive growth. This study underlines how important the impact of predation from human and mammalian predators can be for roe deer survival. We are also grateful to J.‐M. The roe deer abundance in this portion is generally lower than in the southern one (0.01–0.65 individuals harvested annually/km2 of forested area). No visible tail. The objective of this study was to examine how habitat selection by roe deer was influenced by the risk of predation by lynx. Linnaeus first described the roe deer in the modern taxonomic system as Cervus capreolus in 1758. Red deer has buff coloured rump with a ginger buff tail. It reappeared 9.7–9.5 thousand years ago, reaching northern central Europe. Roe deer are fiercely territorial and the males, or bucks, will aggressively defend their territory, especially through the summer. Deer in the southern Czech Republic live in almost completely open agricultural land. Deer have no natural predators in Scotland, so populations must be managed to limit their impacts and to prevent road traffic accidents. In our study area, where roe deer occur across a spatial gradient in abundance and are sympatric with several predators (mainly lynx, foxes and humans) we found that: (1) the risk of lynx predation was negatively related to roe deer abundance; (2) the risk of fox predation was positively related to roe deer abundance; (3) the risk of being preyed upon by lynx and foxes was similar for the two sexes. The meaning of word in Latin is not entirely clear: it may have meant 'ibex' or 'chamois'. To further assess the suitability of this index in our study system, we fitted cox proportional hazard models (see Statistical methods) and used model selection (Burnham and Anderson 2002) to investigate which variables among sex, age and roe deer abundance better described the variation in the risk for a given roe deer of being harvested by a hunter (Appendix). 1996, Okarma et al. Not far away, her twin brother is tucked up in his own secret spot and there they will stay, silent and un-moving, until their mother returns to feed them. 1997, Molinari‐Jobin et al. When last ice age ended the species initially abruptly expanded north of the Alps to Germany during the Greenland Interstadial, 12.5–10.8 thousand years ago, but during the cooling of the Younger Dryas, 10.8–10 thousand years ago, it appears to have disappeared again from this region. In Norway, harvest management goals for roe deer mainly aim to maintain stable populations and hunting success for roe deer is low and not strongly regulated by quotas (Grøtan et al. [36] Roe can now be found in most of rural England except for south-east Kent and parts of Wales, anywhere in the UK mainland suitable for roe may have a population. Eurasian lynx fitness shows little variation across Scandinavian human-dominated landscapes. Find out about managing deer. Males may speed up the process by rubbing their antlers on trees, so that their antlers are hard and stiff for the duels during the mating season. 2010) and it correlates well with other indices of population abundance (Grøtan et al. [14] The Soviet mammalogist Vladimir Sokolov had recognised this as a separate species from 1985 already using electrophoretic chromatography to show differences in the fractional protein content of the body tissues,[15][16] the next year he showed that there were differences in the skull morphology,[citation needed] and a year after he used sonographs to demonstrate that the fawns, females and males made very different noises between species. [18][19] The taxa are differentiated by the B chromosomes found in C. pygargus, populations of this species gain more of these strange 'junk' chromosomes as one moves further east. 2005) and therefore the number of harvested roe deer is likely to reflect changes in roe deer density rather than being an artifact of quotas (Grøtan et al. In support of our first prediction, the risk of fox predation increased with increasing roe deer abundance (Table 3a, Fig. We knew the cause of mortality of 228 animals, after censoring the ones where the radio transmitter stopped working, to avoid bias towards human‐caused mortality. Roe deer (Capreolus capreolus) Red is a much larger species than Roe. 2008). [40], The nematode Spiculopteragia asymmetrica infects this deer. The Bulletin of the Ecological Society of America, I have read and accept the Wiley Online Library Terms and Conditions of Use, The effects of sex, time of birth, and habitat on the vulnerability of roe deer fawns to red fox predation, Ecological correlates of mortality of roe deer fawns in a predator-free environment, Irruptive potential in roe deer: Density-dependent effects on body mass and fertility, Survival, cause-specific mortality, and harvesting of male black-tailed deer in Washington, Patterns of predation by reintroduced European lynx in the Swiss Alps, Effects of severe winters and fox predation on roe deer mortality, Early development and population fluctuations in Soay Sheep, Who wants to live forever? 2012; Fig. A normal life span in the wild is seven to eight years,[31] or 10 years. However, the fact that the number of foxes was three times higher in the southern part of the study area might have contributed to this pattern. [48], A roe deer can live up to 20 years, but it usually does not reach such an age. The Koiné Greek name πύγαργος, transliterated 'pygargos', mentioned in the Septuagint and the works of various writers such as Hesychius, Herodotus and later Pliny,[10] was originally thought to refer to this species (in many European traslations of the Bible), although it is now more often believed to refer to the Addax. Fawns were easily recognized based on size and tooth eruption patterns when captured during winter, and many were originally captured as neonates. Roe deer have a body size a little smaller than a labrador dog, but with long graceful legs. According to Ginsberg and Milner‐Gulland (1994) trophy hunting usually shows extreme selection for adult males in ungulates. 2008a). There have been other, unconfirmed, sightings in County Wicklow. Landscape of risk to roe deer imposed by lynx and different human hunting tactics. Wolves and free‐ranging dogs (Canis familiaris) occur sporadically in the study area and have been documented killing fawns only in a few instances. [25], As of 2008 over 3,000 fossil specimens of this species have been recovered from Europe, which affords a good set of data to elucidate the prehistoric distribution. 2009b). Roe deer will not generally venture into a field that has had or has livestock in it. Mortality is highest in the first weeks after birth due to predation, or sometimes farm machinery; or in the first winter due to starvation or disease, with up to 90% mortality. We then examined how cause‐specific mortality risks were affected by sex, age and roe deer abundance. [7][8], In the English language, this deer was originally simply called a 'roe', but over time the word 'roe' has become a qualifier, and it is now usually called 'roe deer'.[9]. We thus used the Heisey and Fuller estimator (Heisey and Fuller 1985) to calculate cause‐specific mortality rates of roe deer of different sex‐ and age classes with the software Micromort 1.3 (Heisey and Fuller 1985). The lynx population is subject to an annual recreational harvest, such that numbers were more or less stable during the study period. (2008), did not support the results of a higher predation risk from foxes on male fawns with respect to female fawns (Aanes and Andersen 1996). [25], It is thought that during the Middle Ages the two species of roe deer were kept apart due to hunting pressure and an abundance of predators; the different species may have met in the period just before that, but during the Ice Age they were also kept apart. 2002, Nilsen et al. The roe deer population we focus on occurs along a population abundance gradient (due to differences in climate and habitat suitability across the study area), and coexists with several predators; the most important are Eurasian lynx (Lynx lynx), red foxes and human hunters. Learn more. Roe Deer Gestation Period. Young female roe deer can begin to reproduce when they are around 6 months old. This value is rather comparable to the estimate of 42% fawn mortality by foxes from an island in central Norway (Aanes and Andersen 1996). 1992, Milner et al. 2006, Ciuti et al. Roebucks enter rutting inappetence during the July and August breeding season. Number of times cited according to CrossRef: Evaluating habitat suitability and connectivity for a recolonizing large carnivore. Its gestation period is usually about 290 days in length. [49], Population structure is modified by available nutrition, where populations are irrupting there are few animals over six years old. Nonetheless his publication is seen as taxonomically acceptable. 2008). [47], In order to mitigate risk, roe deer remain within refuge habitats (such as forests) during the day. 2009). We distinguished between fawns (<12 months) yearlings (between 12 and 24 months), and adults (>24 months). She is curled up small and her dappled coat blends with her leafy surroundings so effectively that she is almost invisible to potential predators.

Three independent lines of arguments suggest that roe deer hunting bag statistics can serve as a crude measure of roe deer abundance in our study system. Roe deer live in areas of mixed countryside that includes woodland, farmland, grassland and heathland. European wild ungulates represent one of the best studied groups of mammals from the point of view of demography; however the best data come from just a few long‐term studies. 2005, Mysterud and Østbye 2006, Melis et al. In 1884 roe were introduced from Württemberg in Germany into the Thetford Forest, and these spread to populate most of Norfolk, Suffolk, and substantial parts of Cambridgeshire. According to the National Biodiversity Data Centre, in 2014 there was a confirmed sighting of roe deer in County Armagh. Furthermore, there are no large predators in Britain. In 1998, some 2,500,000 deer were shot per year in Western Europe. Estimates date them back to 15-35 million years ago. Therefore, their selection of age and sex classes and relative effects will vary with different ecological and cultural circumstances. [9] He was generally ignored until the 20th century, most 19th century works continued to follow Linnaeus. If not accounted for this could cause declines in harvested roe deer populations, especially in marginal areas (Melis et al. 1997, Soay sheep [Ovis aries] on St Kilda, Clutton‐Brock et al. [50], Compared to the other large herbivores and omnivores in Iran, it is a poor disperser of plant seeds, depite consuming relatively more of them. 1999, roe deer [Capreolus capreolus] in French reserves, Gaillard et al. 2010). It is perhaps ultimately derived from a PIE root *rei-, meaning "streaked, spotted or striped". If I am trying to imitate a roe deer bark, for want of a better word I use ‘bouffff’. [46] It scrapes leaf litter off the ground to make a 'bed'. Although there was uncertainty in the results of the model selection, the best performing model containing the linear and quadratic effect of roe deer abundance was about 2.6 times more likely than the second ranked model. Adult survival probabilities similar to the one recorded in Tredozio have been reported for two enclosed populations in France which were not subjected to predation (0.85 for males and 0.95 for females; Gaillard et al. Males may also use their antlers to shovel around fallen foliage and soil as a way of attracting a mate. Where populations are stagnant or moribund, there is huge fawn mortality and a large part of the population is over seven years old. The animals were manually restrained (without use of anesthetic), aged, sexed, ear‐tagged and radio‐collared before being released. This clearly will have both a range of practical management and life‐history implications (Nilsen et al. For example, Eurasian lynx, when sympatric with roe deer, are roe deer specialist (Jędrzejewski et al. 2009a). 1992, Gaillard et al. To examine how age, sex and roe deer abundance affected the cause‐specific mortality risk, we applied Cox proportional hazard models (Lunn and McNeil 1995, Heisey and Patterson 2006, Murray 2006), and stratified according to cause of mortality as described in Heisey and Patterson 2006.

The best performing model described above was 2.2 times more likely than a model where sex was also included. 2011) and wolves (Liberg et al. 2012). The risk of being harvested by hunters was higher for adult males than adult females and for yearling females than adult females. The main mortality causes were: hunter harvest, predation by lynx, predation by foxes (on fawns) and others (including wolves, dogs, diseases, vehicle collisions and accidents). During the some periods during the last Ice Age it was present in central Europe, but during the Last Glacial Maximum it retreated to refugia in the Iberian Peninsula (two refugia here), southern France, Italy (likely two), the Balkans and the Carpathians. Of these, ... Lynx and Bears, they have no natural predators and their browsing habits heavily impact the environment. Roe deer are the most important prey of lynx (Herfindalet al., 2005), and except from humans, lynx are the most important predator of adult roe deer in this area. 2009b, Melis et al. No sex difference was detected in fawn mortality due to fox (Table 2). In addition fawns had a higher risk of lynx predation than older individuals (Table 3b, Fig. Alexander S. Graphodatsky looked at the karyotypy to present more evidence to recognise these Russian and Asian populations as a separate species, now renamed the eastern or Siberian roe deer (Capreolus pygargus), in his 1990 paper.

It is thought that the Muntjac Deer are one of the oldest deer species. Roe has distinctive black nose and white chin. [28], 22% of the animals around Moscow carry the mtDNA of the European roe deer and 78% of the Siberian. Large Impact of Eurasian Lynx Predation on Roe Deer Population Dynamics. Although the Roe deer's range is growing in the UK, numbers can be affected by culling and by traffic accidents. The roe is a small deer, reddish and grey-brown, and well-adapted to cold environments. 2009, Heurich et al. [27][29] In northeastern Poland there is also evidence of introgression with the Siberian deer, which was likely introduced. The elegant Roe Deer (Capreolus capreolus) is one of six wild deer species that reside in Great Britain. The risk for a given roe deer of being harvested by hunters was higher for adult roe deer compared to fawns and yearlings, and was higher for males than for females. 2009, 2010). (2009b), although the functional response curve in that analysis was also strongly influenced by season and differences in lynx social status. Eurasian lynx (Lynx lynx, lynx hereafter) are the main predators of roe deer in Scandinavia [ 19, 20] although red foxes (Vulpes vulpes) can be important predators of fawns during the first two months of life [ 21, 22 ]. Conversely, consistent with the opportunistic habits of red fox, the risk of being preyed upon by foxes, Plain cream/white rump, can be flared when alarmed. Rump patches differ between the sexes, with the white rump patches heart-shaped on females and kidney-shaped on males. 2010); therefore we expected that hunting mortality would be similar across the abundance gradient. Previous studies from this study system have suggested a strong potential for top‐down control on the roe deer population (Nilsen et al. Our results reflect the different feeding tactics of lynx and foxes: lynx are efficient roe deer specialist (Breitenmoser and Haller 1993, Linnell et al. If an individual was captured as a fawn, it would be reclassified as a yearling in May of the subsequent year and as an adult in May when entering its third year of life, and it would then keep adult status throughout its life.
