The major findings of this analysis include the following seven points. 2), which was well reflected in the dominance of grasses in the feces (in August, 56.4% at YT 3, 38.3% at SA 3; in November, 54.1% at YT 3, 43.5% at SA 3). Fiber content was higher in YT 2 (11.0%) than YT 1 samples (6.4%, Kruskal–Wallis test, χ2 = 9.524, p = 0.009; Steel–Dwass test, t2 = –2.901, p = 0.010), but there was no clear pattern by elevation. Males usually weigh about 90 pounds, while females usually weigh about 70 pounds. Some populations of sika deer are seasonal migrants (Takatsuki et al. You will have access to both the presentation and article (if available). (Photo by Will Parson/Chesapeake Bay Program), 2.5 feet tall at the rump; males weigh about 90 pounds, females weigh about 70 pounds. 3) Understories were dominated by conifers like Tsuga and Abies at YT2 and SA 2. They were analyzed using the Kjaldahl method (Kjeltec 2100 distillation unit). Males have narrow antlers and a dark, shaggy mane on the neck. They vary from pale yellow/brown through to red/brown with white spots in the summer months to dark grey and black in the winter. There is often a … The deer cause vegetational changes and land degradation (Chubu Forest Management Office 2007, 2008, 2010, Nagaike 2012, Masuzawa 2015). However, some have been known to live up to 25 years in captivity. On average, sika deer live 15 to 18 years in the wild. Other common foods of sika deer include poison ivy, catbrier, and marshgrass. This study is the first to quantify and compare the diets of sika deer in lower montane, subalpine and alpine zones of YT and the SA. Sika deer show a north–south variation in diet, from northern grazing populations to southern browsing populations . Our results seem to support these former studies. The specifics of what they will eat depends though on the region where they reside. Diet Sitka deer primarily eat green vegetation. The proportion of monocots was greater in YT 3 samples than YT 1 samples (Kruskal–Wallis test, χ2 = 5.647, p = 0.059; Steel–Dwass test, t2 = –2.402, p = 0.043) but there were not significant differences between YT 1 and YT 2 (t2 = –1.601, p = 0.245) and YT 2 and YT 3 (t2 = –0.164, p = 0.985). Sika deer are known to feed most frequently on trees, shrubs, grasses, sedges, holly, conifers, fungi, acorns, bark, heather, and ivy. Today, t… Dicot content decreased in samples obtained at higher elevation and dicots were significantly more abundant in YT 1 (15.6%) than YT 3 samples (10.1%, Kruskal–Wallis test, χ2 = 3.378, p = 0.025; Steel–Dwass test, t2 = –2.574, p = 0.027). Red deer is the most widespread species, and is also the most commonly farmed deer. Choosing hunting areas that provide some of these food sources may aid your hunting success. When alarmed, adult males emit a distinctive, high-pitched “bark" to alert others to danger. A sika deer's diet can include marsh grasses, fallen leaves, trees, brushy vegetation, herbs, fungi, myrtle bushes, ground ferns, poison ivy, soybeans and corn. Diet: Sika deer primarily feed at dusk through dawn on marsh vegetation, grasses and agricultural crops such as corn and soybeans. When fully grown stags weigh between 40 to 70kg and hinds 30 to 45kgs. Diet Herbivorous; deer feed on vegetation and green leaves of shrubs, along with evergreen forbs and woody browse. 5) Fiber was higher in the feces at SA 1 (20.5% in August, 11.5% in November) than at YT 1 (2.5% in August, 6.4% in November). The mean proportions of the major foods are shown in Fig. They are widely raised in captivity to supply velvet antler for traditional medicine. After about seven months, the female gives birth to a single calf, typically in forested areas or open field.

Radiotelemetry studies on deer movements in central Japan showed that some deer that wintered in the lower areas ascended mountains in early summer, and stayed at the subalpine and alpine zones (Izumiyama and Mochizuki 2008, Izumiyama et al. Ohashi et al. * p < 0.05, ** p < 0.01, *** p < 0.001. Diet: Sika feed on browse, both from coniferous and deciduous species, but especially on grasses and heather in summer. To access this item, please sign in to your personal account. 2) Deciduous trees and shrubs were abundant at SA 1, which was well reflected in the fecal compositions (dicots: 22.8% in August, 25.6% in November), suggesting that dicots were an important food resource regardless of season. During the winter deer tend to eat buds, bark, and shoots, while in the spring and summer time they will generally eat corn, and acorns. In fact, it is generally known that alpine plants are relatively high in nitrogen (Körner 1989). Again, additional studies are needed to quantitatively compare the proportion of pine in habitats, foraging patches and feces to determine if deer avoid this conifer. Cervus (Latin) a stag, deer. It appears they originated from a private residence in Leroy Township and either escaped or were let go. Additional Information: One would be hard-pressed to find information on Ohio’s introduced Sika Deer population. Crude protein content was compared between two study sites by the Mann–Whitney test, and among seasons by the Kruskal–Wallis test with the Steel–Dwass post hoc test. There have been two case studies on the variation in sika deer diet with elevation. Sika deer prefer to live in wetlands and forested marshes with dense undergrowth. The ecological niche occupied by sika deer is similar to whitetail deer and red deer allowing for chances to hybridize. Food: Sika Deer eat vegetation. In SA, monocots (10–20%) and dicots (10–20%) were both prevalent. The proportion of grasses in YT 2 samples (49.5%) was higher than that in YT 1 samples (15.4%, Kruskal–Wallis test, χ2 = 21.263, p = 0.000; Steel–Dwass test, t2 = –3.780, p = 0.000), but the proportions in YT 2 and YT 3 samples (56.4%) were not significantly different (χ2 = –2.041, p = 0.103). 1) Dwarf bamboos were predominant in the feces at YT 1. Create a new folder below. In subalpine zones in YT, grasses are an important food item, comprising about 50% of the samples. Less proportion of fiber at YT 1 may reflect the high abundance of dwarf bamboos at this site which is missing at SA 1 or relatively less woody plants there. Sika deer consumed the same resources that comprised 78% of white-tailed deer diet. Appendix 1. The recent invasion of sika deer into the alpine zone of central Japan reflects the population increase of the deer in the last three decades (Nakajima 2007). Breeding occurs in autumn, beginning in late September. The sika deer varies in color from reddish-brown in the summer to dark brown or black in the winter. The vegetation of YT is a primarily Betula ermanii- and Larix kaempferi-dominated forest with Sasa borealis, a dwarf bamboo, in the understory at YT 1 in the montane zone (Fig. I had sika … Sika Deer in Maryland have Clement Henry to thank for their presence in the coastal state. The habitat use and diet composition of blue sheep (Pseudois nayaur) and Alashan red deer (Cervus alashanicus) in the Helan Mountains, China, were examined from November 2013 to February 2015. In the presence of sika deer, white-tailed deer displayed an increased niche breadth (108%) and a lower diet quality (17%). PSs were compared among the three vegetational zones by the Kruskal–Wallis test with the Steel–Dwass post hoc test. For the YT samples obtained in August, the crude protein content increased with elevation (YT 1–YT 2: Kruskal–Wallis test, χ2 = 42.226, p = 0.000; Steel–Dwass test, t2 = –5.030, p = 0.000; YT 2–YT 3: t2 = –5.092, p = 0.000; Fig. Statistical standard (α) was set at 0.05. Previously found from northern Vietnam in the south to the Russian Far East in the north, it is now uncommon except in Japan, where the species is overabundant. They also were introduced to Europe, North This suggests that a decrease in snow induced by global warming may trigger sika deer expansion further into alpine zones. PS between 10 samples at YT and 10 samples at SA were calculated and 100 PSs were obtained at each vegetational zone. This is the first study to indicate that grasses are an important constituent of the diets of alpine sika deer in Japan. Since only Siberian dwarf pine Pinus pumila shrubs and alpine meadows dominated by Calamagrostis hakonensis, Veratrum album and Potentilla matsumurae grew in the alpine zones (Chubu Forest Management Office 2010), the landscape is open, which is less preferred by sika deer (Takatsuki 1989b). Proportions of the major foods in sika deer feces for each season was compared by the Mann–Whitney U-tests when two sites were available and by the Kruskal–Wallis test, followed by the Steel–Dwass post hoc test when three sites were available (Esumi Mac Statistic Analysis, Ver. 3 (see Supplementary material Appendix 1 Table A1 for other foods). Contact, Password Requirements: Minimum 8 characters, must include as least one uppercase, one lowercase letter, and one number or permitted symbol, Access Institutional Sign In via Shibboleth or OpenAthens, Differences in the fecal compositions by vegetational zones, 1) Comparisons by different vegetational zones, Supplementary material Appendix 1 Table A1, Supplementary material Appendix 1 Table A2, www.env.go.jp/nature/choju/docs/docs4/menkyo.pdf, www.wildlifebiology.org/appendix/wlb-00710. www.chesapeakebay.net. Sitka deer have no upper incisors, and digest vegetation through grinding plant material between their upper and lower molars. However, they can easily adapt to a variety of habitats. Additional studies are needed to quantitatively compare the proportion of grasses in habitats, foraging patches and feces to determine if deer are selective for grasses. Since fiber in the feces indicates less digestible twigs of woody plants and stems of forbs, it is difficult to interpret the fecal compositions by food availability. Since little is known regarding the effects of deer grazing in the alpine zone of central Japan (but see Nagaike 2012, Watanabe et al. Mating & Reproduction in Sika Deer In Europe the breeding season or rut for Cervus nippon takes place between September and November. 2008). There was a higher proportion of dwarf bamboo (41.2%) in YT 1 than YT 2 (0.2%, Mann–Whitney test, U = 0, p = 0.000). 3). By comparison, an average adult man in Britain is 1.77m high and weighs 79kg. Fecal samples of sika deer were collected from the low montane (YT 1, SA 1), the subalpine (YT 2, SA 2) and the alpine zones (YT 3, SA 3). Only fiber content increased from August to November in YT 3 samples (U = 11.0, p = 0.003). The water content was determined using the atmospheric pressure drying method (135°C for 2 h). A. Ohtsu and S. Yamamoto helped the analysis. Location map of Mt Yatsugatake (YT) and the Japanese South Alps (SA). In the lower mountain in YT, dwarf bamboo comprised 40–55% of the plant compositions in fecal samples, whereas dicots were mostly found in SA samples. Sika Deer are very opportunistic when it comes to the foods they eat. The sika deer is a small, brown elk introduced from Asia that lives in quiet marshes and forested wetlands on the lower Eastern Shore of Maryland. 5). Views of the sampling sites of deer feces at the montane zone (YT 1, SA 1), the sub-alpine zone (YT 2, SA 2) and the alpine zone (YT 3, SA 3) of Mt Yatsugatake (YT 1–YT 3) and the Japanese South Alps (SA 1–SA 3). (2014) analyzed the factors associated with this phenomenon and showed that the range expansion occurred in areas with less snow. 2004). Sika deer not only excert effects on plants but also on abundance of birds (Okuda et al. The coastal forests here are poor in minerals, washed out by the continuous rain and snow. Sika, rusa and sambar populations occur only in the North Island. They were also compared among vegetational zones by the Kruskal–Wallis test with the Steel–Dwass post hoc test. As a result they seem to do very well finding enough to survive on. In central Japan, they inhabit subalpine and alpine zones from June to November, and then descend to lower elevations during the winter (Izumiyama and Mochizuki 2008, Izumiyama et al. Deer are herbivores and generally eat grass, nuts, twigs, alfalfa, corn, fruit, and fungi. However, the proportions in the feces were small (in August, 4.1% at YT 2, 2.7% at SA 2; in November, 2.5% at YT 2, 1.8% at SA 2), suggesting that conifers were not an important food source regardless of their abundance. 2012), the results of this study are important for future alpine deer management. The fresh kelp is a crucial supplement to the Sika’s diet, and they are willing to risk the dangers they could encounter here. The proportion of grasses in YT 2 samples (47.3%) was significantly higher than that in YT 1 samples (22.7%, Kruskal–Wallis test, χ2 = 18.324, p = 0.000; Steel–Dwass test, t2 = –3.275, p = 0.003), but there was no significant difference between YT 2 and YT 3 samples (54.1%; t2 = –1.471, p = 0.305). 3), but the difference was not significant (YT 1–YT 2: Kruskal–Wallis test, χ2 = 3.888, p = 0.143; Steel–Dwass test, t2 = –1.022, p = 0.563, YT 1–YT 3: t2 = –1.967, p = 0.121, YT 2–YT 3: t2 = 0.910, p = 0.634). There have been two case studies on the variation in sika deer diet with elevation. Terms of Use | This might be due to the calm nature of sitka deer which make them popular pets for a deer species. 3). 2009, Takii et al. YT 1: Sasa borealis, a dwarf bamboo, was abundant, YT 2: undergrowth was poor, YT 3: Siberian dwarf pine shrubs were dominant, SA 1: forbs and browses grew, SA 2: understory was poor, SA 3: Siberian dwarf pine shrubs and alpine meadow grew. We can help you reset your password using the email address linked to your BioOne Complete account. Error bars indicate SD. Sika deer are very vocal and communicate with one another using at least 10 different sounds. During the warmer months they eat nuts, corn and acorns -- and a lot more green matter. We randomly walked in the forests and shrubs, and collected fresh pellets (n = 20) from fecal piles (n = 10). For example, wapiti C. elaphus canadensis in Alberta, Canada, migrated to the alpine zone to forage on high-protein plants (Morgantini and Hudson 1989, Hebblewhite et al. They are primarily nocturnal. 3.0, 2018). Sika deer have a white rump and white spots on their back. Sampling sites of sika deer feces in Mt Yatsugatake (YT 1–3) and the Japanese South Alps (SA 1–3). In 2015, there were 65% fewer hunters than in 1975 (< www.env.go.jp/nature/choju/docs/docs4/menkyo.pdf>). Funding – This study was partly supported by Natural Parks Foundation (Volunteer Fund for Nature Conservation 2011). The mother nurses her newborn calf for up to 10 months on increasingly fatty milk. akaishimontanum. Error bars indicate SD. and Acer spp., and both deer showed strong selectivity for E. verrucosus, E. alatus and Populus davidiana (EI>0.85) in spite of their low availability. Sika deer, the graceful spotted deer of Japanese and Chinese art, originally were native to Asia from far-east Russia to Vietnam to the islands of Japan and Taiwan. 1). The fecal protein content was higher in SA 1 samples (U = 82.5, p = 0.004) and SA 3 samples (U = 66.0, p = 0.001) collected in August than in November, but was higher in November than August for the SA 2 samples (U = 90.0, p = 0.003). The typical diet of the white-tailed deer does not remain constant all year long. Goyo, northern Honshu (the main island of Japan), were studied.Among 88 plant species found in surveys, 36 species (40.9%) were eaten by the deer. Since the alpine zones in central Japan have not yet been inhabited by deer until the late 1990s, no study has been done on the food habits of alpine sika deer. Browse is more important in winter. Brandishing a brightly flushed face and leaving her dignity at the door, Kristen managed to find a gap and charged her way through like a blocker to the end zone. Sike deer have a varied diet, which they adapt to their environment. Thus, there was no consistent seasonal change in fecal crude protein. The principal winter food items of red and sika deer were Euonymus spp. Diet and Nutrition Sika deer is herbivores and can eat any of the following: trees, fallen leaves, marsh grasses, brushy vegetation, herbs, fungi, ground ferns, bamboo, poison ivy, corn and soy beans. It may explain the reason of the recent invasion of the sika deer to the alpine zone. However, the deer’s dependence on snacks given to them by tourists has been impacted by recent response to concerns over the coronavirus outbreak. The sika deer is a small, brown elk that lives in quiet marshes and forested wetlands on the lower Eastern Shore of Maryland. The percentage frequency of feeding (F) was highest for graminoids (59.6%), followed by browses (16.6%) and ferns (7.7%) and lowest for forbs (5.4%).). 4) Our qualitative observations of habitats indicated that grasses were abundant in the alpine zone (Fig. Sika deer are native to Japan, Taiwan and eastern Asia, and were introduced into the Chesapeake Bay watershed in 1916. Browse is more important in winter. This functionality is provided solely for your convenience and is in no way intended to replace human translation. In SA 3 samples, only fiber decreased from August to November (U = 2.728, p = 0.006). A sika deer's diet can include any of the following: marsh grasses, fallen leaves, trees, brushy vegetation, herbs, fungi, bamboo, ground ferns, poison ivy, soy beans, and corn depending on environmental conditions (Feldhamer 1980). Marsh grasses, fallen leaves, trees, brushy vegetation, herbs, fungi, ground ferns, poison ivy, soybeans and corn. Males are called “stags” and females are called “hinds” or “cows.". They typically feed at night. Any meat can taste good if cooked correctly. Since ruminants often face protein deficiency (Robbins 1992), high-protein plants are nutritionally valuable and the alpine zone is likely advantageous for sika deer in terms of forage quality. 1). In SA 2 samples, grasses (Mann–Whitney test, U = 1.965, p = 0.049) and monocots (U = 2.116, p = 0.034) decreased while dicots (U = 3.479, p = 0.001) and culms (U = 3.712, p < 0.001) increased. Another study on Yakushima Island, southern Japan, found that sika deer at low elevation ate more dicot leaves, while those in the alpine zone mainly ate Pseudosasa owatarii bamboo (Takatsuki 1990b). Fallow deer were introduced from 1860 and are now found in many low-altitude forests, partly the result of farm escapes. They were first introduced in the Chesapeake Bay watershed on James Island in Dorchester County, Maryland, in 1916. Although differences in sika deer diet by vegetational zones have been studied previously (Takatsuki 1983, 1990b, 2009a), the alpine zone in central Japan has been inhabited by sika deer only for the last two decades and had not been studied until now. At SA 1, only fiber content decreased from August to November (Kruskal–Wallis test, χ2 = 13.553, p = 0.001; Steel–Dwass test, t2 = 2.839, p = 0.013) and increased from November to March (t2 = –3.027, p = 0.007). When do deer shed their antlers? There was relatively more fiber in SA samples, but the values declined with elevation although difference was not significant among the sites (Kruskal–Wallis test, χ2 = 4.555, p = 0.103; SA 1–SA 2: Steel–Dwass test, t2 = –2.847, p = 0.012; SA 1–SA 3: t2 = –1.444, p = 0.318, SA 2–SA 3: t2 = –1.627, p = 0.234, Fig. Supplementary material (available online as Appendix wlb-00710 at < www.wildlifebiology.org/appendix/wlb-00710>). The PS values were significantly different between the lower elevation montane zone (YT 1, SA 1) and the subalpine zones (YT 2, SA 2) (August: Kruskal–Wallis test, χ2 = 210.134, p = 0.000; Steel–Dwass test, t2 = –11.895, p = 0.000; November: Kruskal–Wallis test, χ2 = 156.252, p = 0.000; Steel–Dwass test, t2 = –3.184, p = 0.004) and the subalpine and the higher elevation alpine zones (YT 3, SA 3) (August: Steel–Dwass test, t2 = –5.837, p = 0.000, November: Steel–Dwass test, t2 = –10.244, p = 0.000). Sika deer primarily use vigilance to protect themselves from predators, often fleeing when threatened. Translations are not retained in our system. 5); the pattern was similar in November (YT 1–YT 2: Kruskal–Wallis test, χ2 = 31.699, p = 0.000; Steel–Dwass test, t2 = –2.629, p = 0.023; YT 2–YT 3: t2 = 4.060, p = 0.000). The importance of good tasting deer meat lies more with the meat preparation then with the specie of deer. This will count as one of your downloads. However, observations of the subalpine habitat indicated that grasses were not abundant in these habitats (Fig. In the wintertime food is significantly harder to find, and deer eat a lot of buds, bark and shoots then. The rumen contents of sika deer (Cervus nippon Temminck) on the Boso Peninsula, central Japan, were analyzed to identify local, sexual and age‐specific differences in food habits.Graminoids and woody plants were the primary foods throughout the year. Fecal composition in three vegetational zones was compared between August and November at YT and SA (Supplementary material Appendix 1 Table A1). There were more dicots in SA 2 samples (25.0%) than SA 3 samples (10.4%, t2 = 2.837, p = 0.013). 2012). An institutional or society member subscription is required to view non-Open Access content. Reproduction Deer have 1-2 fawns annually, with twins being most common in does of prime breeding age. You have requested a machine translation of selected content from our databases. For the SA samples obtained in August, no significant difference was found between SA 1 and SA 2 samples (Kruskal–Wallis test, χ2 = 29.375, p = 0.000; Steel–Dwass test, t2 = 0.292, p = 0.954), but SA 3 samples had significantly higher crude protein than SA 2 samples (t2 = 6.480, p = 0.000). It is 100 km long and 50 km wide. The proportion of culms seemed to increase with elevation (Fig. Prof. T. Iriki at Azabu University advised the analysis of crude protein contents. Crude protein contents were higher at higher zones (15–20%) than at lower zones (8–12%) in both study areas. In August, the mean proportion of dwarf bamboo in YT 1 samples was 55.4%, which was significantly greater than in YT 2 samples (0.1%; Kruskal–Wallis test, χ2 = 23.079, p = 0.000; Steel–Dwass test, t2 = 3.963, p = 0.000) and YT 3 samples (0.2%; t2 = 3.862, p = 0.000; Fig. The proportion of culms was not different between SA 1 (25.6%) and SA 2 samples (25.0%, Kruskal–Wallis test, χ2 = 1.235, p = 0.539; Steel–Dwass test, t2 = 0.416, p = 0.909), but SA 2 samples had significantly more culms than SA 3 samples (10.0%, t2 = 2.837, p = 0.013). Most sika deer breed in their second year, but about one-quarter breed in their first year. The proportion of grasses was not significantly different between SA 1 (12.3%) and SA 2 samples (10.6%, t2 = 0.718, p = 0.753), but SA 3 samples had a higher proportion of grasses (23.7%) than SA 1 samples (t2 = –3.026, p = 0.007). Yasunori Kagamiuchi, Seiki Takatsuki "Diets of sika deer invading Mt Yatsugatake and the Japanese South Alps in the alpine zone of central Japan," Wildlife Biology, 2020(3), (19 August 2020), Registered users receive a variety of benefits including the ability to customize email alerts, create favorite journals list, and save searches. In the alpine zone of both YT and SA, grasses were present the fecal samples (50% and 10–20%, respectively). The plants that incur damage from sika deer include the endangered Viola crassa yatsugatakeana, Cypripedium yatabeanum and Coeloglossum viride var. 3), but only the difference between YT 2 (19.6%) and YT 1 samples was significant (10.4%, t2 = –3.105, p = 0.005). 5 (Supplementary material Appendix 1 Table A2). 2004, Sakuragi et al. 2). Bayberry, catbrier, and poison ivy are a few of the preferred food choices. Despite these negative environmental factors, the alpine zone seems to provide high-quality forage. Since ruminants are often protein-deficient (Robbins 1992), the protein content of forage is important. YT (the summit: 36°00′N, 138°22′E), situated in the eastern part of Nagano Prefecture, is 15 km wide and 25 km long. Samples at YT 3 did not contain dwarf bamboo. The above changes were not consistent among sites; for example, fiber increased in samples obtained from two YT sites from August to November, but decreased in those collected from two SA sites. This study assessed the composition of sika deer diets and compared nutritional quality between the low montane, subalpine and alpine zones. Sika deer also have a dark stripe down their back from head to tail, which the white-tailed deer lack. A male sika deer will mate with multiple females over a breeding season, gathering as many as 12 females on his territory each year. The composition similarity of the deer fecal samples in each vegetational zone was compared between YT and SA by Whittaker's percentage similarity (PS, Whittaker 1952). This study has demonstrated the value of fecal analysis which can be compared to plant abundance within habitat to test for dietary preferences in the future. Sika deer are similar to Fallow deer in coat colour. It is likely that the sika deer population expanded their range into higher areas, starting in the montane zone, followed by subalpine coniferous forests, and finally the alpine zone. 4). Their effects on the alpine plants are large: many alpine forbs have shown a decline, while unpalatable forbs, such as Ligularia dentata, Senecio cannabifolius and Artemisia sinanensis thrive (Takatsuki 1989b, Watanabe et al. Sika deer may be quite small- to medium-sized, depending on the region where they live and the food sources they have available. They typically feed at night. A study on bighorn sheep Ovis canadensis in southeastern Canadian Cordillera showed that plants at higher zones were more digestible and contained more protein, phosphorous and cellulose than plants at lower elevations (Johnston et al. The brown algae are rich in both nutrients and salts. These are areas where you grow the foods they are particularly drawn to, like grass, nuts, alfalfa, fungi, fruit, corn, apples, clover, leaves, sedges, and sumac foliage. Another likely factor is the decline in hunting pressure, which has decreased over the last three decades and may minimize the avoidance of open alpine zones by sika deer (Takatsuki 1989a). Their diet fluctuates all year to what is available each season. This content is available for download via your institution's subscription. In her fragile and panic-stricken state, Kristen was no longer so enthusiastic about feeding the sika deer of Nara deer park! Sika deer Cervus nippon populations have been increasing on the Japanese archipelago. Regarding culms, the proportion tended to be greater at higher elevations zones (Fig. The Chesapeake Bay Program is a unique regional partnership that has led and directed the restoration of the Chesapeake Bay since 1983. The sika deer (Cervus nippon) also known as the spotted deer or the Japanese deer, is a species of deer native to much of East Asia and introduced to other parts of the world. No differences were found in YT 2 samples by month in most of the food plants: dwarf bamboo (Mann–Whitney test, U = 31.5, p = 0.154), grasses (U = 41.5, p = 0.775), monocots (U = 35.0, p = 0.414), dicots (U = 23.5, p = 0.079), culms (U = 41.0, p = 0.744) and fiber (U = 26.5, p = 0.130). Nippon (Japanese) Japan. Percent similarities (PS) of sika deer fecal sample compositions between Mt Yatsugatake (YT) and the Japanese South Alps (SA), collected from different vegetational zones in August (light) and November (dark) 2011. The PS values between YT and SA increased with elevation in both August and November (Fig. Privacy Policy, Chesapeake Bay Program There was no significant difference among SA samples: SA 1–SA 2 (Kruskal–Wallis test, χ2 = 3.050, p = 0.218; Steel–Dwass test, t2 = 1.399, p = 0.341), SA 1–SA 3 (t2 = –0.151, p = 0.987) and SA 2–SA 3 (t2 = –1.589, p = 0.251). Plant fragments were spread over a glass slide (1 mm grid size) and categorized into 11 groups: dwarf bamboo, grasses, sedges, other monocots, dicots, coniferous leaves, dicots, ferns, culms and sheaths, fiber, fruits and seeds, and others. However, during the intense Alaskan winters, they also feed on woody vegetation and lichens. SA (the summit: 35°45′N, 138°14′E) is situated in the southeastern part of Nagano Prefecture, bordering the Yamanashi and Shizuoka Prefectures (Fig. Females may associate with several males in order to gain access to a variety of feeding grounds. They have a smaller head and shorter legs compared to other more common deer. In the last three decades, sika deer Cervus nippon populations have been increasing and expanding their range in Japan (Nakajima 2007), thus exerting an impact on vegetation (Akashi and Terazawa 2005, Ohashi et al. Sika deer are a medium to large sized deer that stand at around 0.70 to 0.95m tall at the shoulder for males (stags) and 0.50 to 0.70m for females (hinds). With many people avoiding large public gathering spaces such as parks, as well as a drop in tourism in general, the deer are now desperately traveling further away from the park in search of food. 2009). Some studies focusing on the foods of alpine ungulates provide evidence for the protein benefits of alpine vegetation. There was a larger proportion of fiber in YT 2 samples (8.5%) than YT 1 samples (2.5%, Kruskal–Wallis test, χ2 = 8.651, p = 0.013; Steel–Dwass test, t2 = –2.847, p = 0.012), but there was no difference between any other pair of sites.
