Sitka deer have no upper incisors, and digest vegetation through grinding plant material between their upper and lower molars. This is because, depending on where you live, these food sources can be nearly impossible to grow. Literature Cited Kurt, F. 1990. 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. 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). 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). Your use of this feature and the translations is subject to all use restrictions contained in the Terms and Conditions of Use of the BioOne website. PS between 10 samples at YT and 10 samples at SA were calculated and 100 PSs were obtained at each vegetational zone. Create a new folder below. This will count as one of your downloads. It took 7 days and 8 days for collection at YT and SA, respectively. 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. The PS values between YT and SA increased with elevation in both August and November (Fig. While they reside in the Bay watershed year round, the sika deer’s summer range is generally larger than its winter range. Marsh grasses, fallen leaves, trees, brushy vegetation, herbs, fungi, ground ferns, poison ivy, soybeans and corn. 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. Browse is more important in winter. Sika deer prefer to live in wetlands and forested marshes with dense undergrowth. 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. 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. 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. There have been two case studies on the variation in sika deer diet with elevation. 3), but only the difference between YT 2 (19.6%) and YT 1 samples was significant (10.4%, t2 = –3.105, p = 0.005). Red deer is the most widespread species, and is also the most commonly farmed deer. 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). 1) Dwarf bamboos were predominant in the feces at YT 1. 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. Fax: (410) 267-5777, © 2021 Chesapeake Bay Program All Rights Reserved In subalpine zones in YT, grasses are an important food item, comprising about 50% of the samples. A male Sika deer’s antlers generally have three to four points or tines, though the more mature and dominant stags have more. Choosing hunting areas that provide some of these food sources may aid your hunting success. When do deer shed their antlers? 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. 2012), the results of this study are important for future alpine deer management. 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. 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 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. The sika deer, like other species, are herbivore – or more precisely, folivore – depending on plant matters for food, including leaves, roots, tubers, soft wood, bark, stems, seeds, grains, fruits, and nuts. Of course, feeding deer during the winter is more of a challenge. The principal winter food items of red and sika deer were Euonymus spp. Diet: Sika deer primarily feed at dusk through dawn on marsh vegetation, grasses and agricultural crops such as corn and soybeans. A similar pattern was also observed in November (Fig. Despite these negative environmental factors, the alpine zone seems to provide high-quality forage. We analyzed sika deer fecal samples from Mt Yatsugatake (YT) and the Japanese South Alps (SA). 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. In the presence of sika deer, white-tailed deer displayed an increased niche breadth (108%) and a lower diet quality (17%). 2009). These coniferous trees were densely planted, and prevented understory growth (Takatsuki 1990a), which resulted in a low carrying capacity of the deer. * p < 0.05, ** p < 0.01, *** p < 0.001, NS: not significant. To access this item, please sign in to your personal account. We chose Mt Yatsugatake (YT) and the Japan South Alps (SA) as the study sites (Fig. Fecal pellets (n = 10) were dried at 65°C for 24 h and milled. 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. This content is available for download via your institution's subscription. Cervus (Latin) a stag, deer. They typically feed at night. 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. In summary, dwarf bamboo was abundant in YT 1 samples and grasses were abundant in samples obtained at higher elevation in August. Location map of Mt Yatsugatake (YT) and the Japanese South Alps (SA). 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). 2), a coniferous Tsuga diversifolia and Abies veitchii forest with T. diversifolia, Picea jezoensis, A. veitchii and Betula ermanii at YT 2 in the subalpine zone, and Siberian dwarf pine Pinus pumila shrubs and alpine meadows dominated by Calamagrostis hakonensis, Veratrum album and Potentilla matsumurae at YT 3 in the alpine zone (Chubu Forest Management Office 2010). During breeding, males emit a long, multi-pitched wail. Ohashi et al. Sika deer primarily use vigilance to protect themselves from predators, often fleeing when threatened. Prof. T. Iriki at Azabu University advised the analysis of crude protein contents. It appears they originated from a private residence in Leroy Township and either escaped or were let go. Diet Herbivorous; deer feed on vegetation and green leaves of shrubs, along with evergreen forbs and woody browse. 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). Fecal samples were washed over a 0.5 mm aperture sieve, and the remaining material was microscopically analyzed using the point-frame method (Chamrad and Box 1964, Takatsuki 1978). However, their antlers and sharp hooves can also be used in defense. www.chesapeakebay.net. 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. Native to Sri Lanka and India, the Axis deer were brought to the United States in 1932 and … Above, a sika deer feeds on grass at the Chesapeake Bay Foundation’s Karen Noonan Center in Dorchester County, Md., on Aug. 2, 2017. Females may associate with several males in order to gain access to a variety of feeding grounds. 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). Fallow deer were introduced from 1860 and are now found in many low-altitude forests, partly the result of farm escapes. Nippon (Japanese) Japan. Sampling sites of sika deer feces in Mt Yatsugatake (YT 1–3) and the Japanese South Alps (SA 1–3). Because sika deer are forest dwellers (Geist 1998, Takatsuki 2006), the alpine zone does not seem to be a suitable habitat for them because of the steep topography and lack of trees. Females usually live in small groups with their young. Crude protein content in sika deer feces collected from Mt Yatsugatake (YT 1–3) and the Japanese South Alps (SA 1–3) in August and November 2011. The proportions of coniferous leaves in the feces were more at these subalpine sites than at other vegetational zones. The fecal protein content at YT 1 was significantly higher in November than in August (Mann–Whitney test, U = 21.0, p = 0.000; Supplementary material Appendix 1 Table A2), but no seasonal difference was found in YT 2 samples (U = 94.0, p = 0.200) or YT 3 samples (U = 106.0, p = 0.075). 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. 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). 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. They were first introduced in the Chesapeake Bay watershed on James Island in Dorchester County, Maryland, in 1916. There is often a … Privacy Policy, Chesapeake Bay Program 1968). Members of Bernina Alpine Club supported techniques of mountaineering. They eat what is easily accessible. 2), with a coniferous Abies veitchii–Abies mariesi forest at SA 2 in the subalpine zone, and dwarf pine shrubs and alpine meadows at SA 3 in the alpine zone (Chubu Forest Management Office 2007). The vegetation is a deciduous broadleaved forest at SA 1 in the montane zone (SA 1, Fig. Some studies focusing on the foods of alpine ungulates provide evidence for the protein benefits of alpine vegetation. akaishimontanum. In the alpine zone of both YT and SA, grasses were present the fecal samples (50% and 10–20%, respectively). Males are called “stags” and females are called “hinds” or “cows.". Breeding occurs in autumn, beginning in late September. 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. The sika deer is regarded as sacred in Japan. Sika deer are very vocal and communicate with one another using at least 10 different sounds. Crude protein contents were higher at higher zones (15–20%) than at lower zones (8–12%) in both study areas. Additionally, deciduous forests were logged and coniferous trees, such as Cryptomeria japonica and Chamaecyparis obtusa, were intensively planted during the 1960s and the 1970s (Agetsuma 2007). On average, sika deer live 15 to 18 years in the wild. Tel: (800) YOUR-BAY (968-7229) 2012, Hashimoto and Fujiki 2014, Masuzawa 2015), and soil erosion has also been accelerated (Chubu Forest Management Office 2007). 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. While many subspecies are in danger, the species as a whole is thriving, with numerous introduced populations in the British Isles, New Zealand, and the United States. Today, t… Since vegetation differs with elevation, it is expected that the food habits of sika deer would also differ by vegetational zone. The proportion of dicots in SA 1 samples (22.8%) was greater than that in SA 2 samples (6.8%, Kruskal–Wallis test, χ2 = 14.400, p = 0.000; Steel–Dwass test, t2 = 3.554, p = 0.001); the proportion of dicots in SA 3 samples (12.3%) was significantly greater than that in SA 2 samples (6.8%, t2 = –2.385, p = 0.045). Sika deer not only excert effects on plants but also on abundance of birds (Okuda et al. This might be due to the calm nature of sitka deer which make them popular pets for a deer species. When fully grown stags weigh between 40 to 70kg and hinds 30 to 45kgs. 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. Any meat can taste good if cooked correctly. Terms of Use | 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. When alarmed, adult males emit a distinctive, high-pitched “bark" to alert others to danger. Sika deer are native to Japan, Taiwan and eastern Asia, and were introduced into the Chesapeake Bay watershed in 1916. In YT 1 samples collected from August to November, there was a decrease in dwarf bamboo (Kruskal–Wallis test, χ2 = 7.961, p = 0.019; Steel–Dwass test, t2 = 2.721, p = 0.016), but increases were seen in monocots (Kruskal–Wallis test, χ2 = 9.441, p = 0.009; Steel–Dwass test, t2 = –2.509, p = 0.032), dicots (Kruskal–Wallis test, χ2 = 15.522, p = 0.000; Steel–Dwass test, t2 = –3.707, p = 0.001) and fiber contents (Kruskal–Wallis test, χ2 = 14.307, p = 0.001; Steel–Dwass test, t2 = –2.620, p = 0.024). A male sika deer will mate with multiple females over a breeding season, gathering as many as 12 females on his territory each year. 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). 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. 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. 5 (Supplementary material Appendix 1 Table A2). Bayberry, catbrier, and poison ivy are a few of the preferred food choices. Other common foods of sika deer include poison ivy, catbrier, and marshgrass. The mean proportions of the major foods are shown in Fig. 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). Adult females use soft bleats and whistles to communicate with their young and other females, while young deer emit a soft, horse-like neigh when communicating with their mother. 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. Proportions of the major foods in sika deer feces obtained from the montane (YT 1, SA 1), the middle subalpine (YT 2, SA 2) and the alpine zones (YT 3, SA 3) in Mt Yatsugatake (YT 1–3) and the Japanese South Alps (SA 1–3). We collected sika deer fecal pellets from three vegetational zones: the montane zone (YT 1, SA 1), the subalpine zone (YT 2, SA 2) and the alpine zone (YT 3, SA 3) in YT and SA (Table 1) in August and November 2011, and in March 2012. 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. There have been two case studies on the variation in sika deer diet with elevation. Error bars indicate SD. Regarding culms, the proportion tended to be greater at higher elevations zones (Fig. 2). Sika deer may be quite small- to medium-sized, depending on the region where they live and the food sources they have available. Furthermore, alpine weather is unstable and may become cold even in summer. 3). 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). Most sika deer breed in their second year, but about one-quarter breed in their first year. 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). Some of the common types of food that they are known to eat include grass, leaves, shoots, and twigs. (Photo by Will Parson/Chesapeake Bay Program), Male sika deer live in groups with other males during spring and summer. 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. Mating & Reproduction in Sika Deer In Europe the breeding season or rut for Cervus nippon takes place between September and November. (Photo by Will Parson/Chesapeake Bay Program), A sika deer feeds on underwater grasses near the Chesapeake Bay Foundation’s Karen Noonan Center in Dorchester County, Md., on Aug. 2, 2017. 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). Sika deer have a white rump and white spots on their back. Sika deer Cervus nippon populations have been increasing on the Japanese archipelago. The importance of good tasting deer meat lies more with the meat preparation then with the specie of deer. 1). 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. 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. 2016) and soil erosion (Yamada and Takatsuki 2015) through vegetational changes. Sike deer have a varied diet, which they adapt to their environment. Sika deer grow to about 2.5 feet tall at the rump. 7) Crude protein contents were higher at higher vegetational zones (Fig. 2009, Takii et al. 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. 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. Samples at YT 3 did not contain dwarf bamboo. 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). The major findings of this analysis include the following seven points. Please note that a BioOne web account does not automatically grant access to full-text content. Sika deer show a north–south variation in diet, from northern grazing populations to southern browsing populations . Sika, rusa and sambar populations occur only in the North Island. 2004, Sakuragi et al. Although they are called deer, sika deer are actually a member of the elk family. Sike deer have a varied diet, which they adapt to their environment. By comparison, an average adult man in Britain is 1.77m high and weighs 79kg. Sika deer are similar to Fallow deer in coat colour. As a result they seem to do very well finding enough to survive on. 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.

The typical diet of the white-tailed deer does not remain constant all year long. Sika Deer are very opportunistic when it comes to the foods they eat. 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). There were relatively more grasses in samples obtained at higher zones. In SA 3 samples, only fiber decreased from August to November (U = 2.728, p = 0.006). Sika is Japanese for a small deer. This study assessed the composition of sika deer diets and compared nutritional quality between the low montane, subalpine and alpine zones. Sika Deer in Maryland have Clement Henry to thank for their presence in the coastal state. Diet Sitka deer primarily eat green vegetation. In the wintertime food is significantly harder to find, and deer eat a lot of buds, bark and shoots then. (2014) analyzed the factors associated with this phenomenon and showed that the range expansion occurred in areas with less snow. Its native predators include tigers and wolves. Sika deer consumed the same resources that comprised 78% of white-tailed deer diet. 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). The mother nurses her newborn calf for up to 10 months on increasingly fatty milk. It has white spots on its back and a white rump. They have a smaller head and shorter legs compared to other more common deer. The objective of this study was to characterize the botanical compositions and crude protein contents of the feces of sika deer according to elevation in central Japan. During the warmer months they eat nuts, corn and acorns -- and a lot more green matter. The deer cause vegetational changes and land degradation (Chubu Forest Management Office 2007, 2008, 2010, Nagaike 2012, Masuzawa 2015). In winter, the use of evergreen broad leaves increased. Sika deer are primarily found on Maryland’s lower Eastern Shore. The food habits of Sika deer (Cervus nippon) on Mt. 3) Understories were dominated by conifers like Tsuga and Abies at YT2 and SA 2. They were also compared among vegetational zones by the Kruskal–Wallis test with the Steel–Dwass post hoc test. 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. They also were introduced to Europe, North 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. A related deer is the wapiti, which occurs in northern Fiordland. The coastal forests here are poor in minerals, washed out by the continuous rain and snow. They are primarily nocturnal. Deer are herbivores and generally eat grass, nuts, twigs, alfalfa, corn, fruit, and fungi. 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). 3). Error bars indicate SD. 3 (see Supplementary material Appendix 1 Table A1 for other foods). There were more grasses in samples obtained at higher elevation. However, the deer’s dependence on snacks given to them by tourists has been impacted by recent response to concerns over the coronavirus outbreak. In November, SA 2 samples had more crude protein than SA 1 samples (Kruskal–Wallis test, χ2 = 32.559, p = 0.000; Steel–Dwass test, t2 = –5.410, p = 0.000), but no difference was found between SA 2 and SA 3 samples (t2 = –2.003, p = 0.112). The effect of sika deer on alpine vegetation has become more prominent since 2000, specifically on Mt Yatsugatake (YT) and the Japanese South Alps (SA; Chubu Forest Management Office 2007, 2008, 2010). In 2015, there were 65% fewer hunters than in 1975 (< www.env.go.jp/nature/choju/docs/docs4/menkyo.pdf>). 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. Fecal composition in three vegetational zones was compared between August and November at YT and SA (Supplementary material Appendix 1 Table A1). Some populations of sika deer are seasonal migrants (Takatsuki et al. Axis Deer. 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). However, they can easily adapt to a variety of habitats. This functionality is provided solely for your convenience and is in no way intended to replace human translation. 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). Translations are not retained in our system. During mating season, males rapidly deplete their fat stores and may lose up to 30% of their body weight. Grasses were also relatively abundant in the feces at the subalpine zones (in August, 49.9% at YT 2, 33.3% at SA 2; in November, 47.3% at YT 2, 21.5% at SA 2).

Our results seem to support these former studies. Thus, there was no consistent seasonal change in fecal crude protein. 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. I had sika … There was a small proportion of monocots in samples from all zones, and the values were not significantly different between the zones, except between YT 1 (0.4%) and YT 2 (5.6%, Kruskal–Wallis test, χ2 = 54.529, p = 0.001; Steel–Dwass test, t2 = –3.732, p = 0.001). Only fiber content increased from August to November in YT 3 samples (U = 11.0, p = 0.003). Since the crude protein content of sika deer feces is relative to that within their rumen (Watanabe and Takatsuki 1993), we used fecal crude protein as an index for food quality. The water content was determined using the atmospheric pressure drying method (135°C for 2 h).
