In summary, dwarf bamboo was abundant in YT 1 samples and grasses were abundant in samples obtained at higher elevation in August. Its native predators include tigers and wolves. It appears they originated from a private residence in Leroy Township and either escaped or were let go. While they reside in the Bay watershed year round, the sika deer’s summer range is generally larger than its winter range. 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). Fax: (410) 267-5777, © 2021 Chesapeake Bay Program All Rights Reserved In the wintertime food is significantly harder to find, and deer eat a lot of buds, bark and shoots then. 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. Males have narrow antlers and a dark, shaggy mane on the neck. 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. We chose Mt Yatsugatake (YT) and the Japan South Alps (SA) as the study sites (Fig. In the alpine zone of both YT and SA, grasses were present the fecal samples (50% and 10–20%, respectively). 2004, Sakuragi et al. 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. They were first introduced in the Chesapeake Bay watershed on James Island in Dorchester County, Maryland, in 1916. 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). Food Habits. 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). On average, sika deer live 15 to 18 years in the wild. 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). Browse is more important in winter. They were also compared among vegetational zones by the Kruskal–Wallis test with the Steel–Dwass post hoc test. Fecal pellets (n = 10) were dried at 65°C for 24 h and milled. The deer cause vegetational changes and land degradation (Chubu Forest Management Office 2007, 2008, 2010, Nagaike 2012, Masuzawa 2015). 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). Most sika deer breed in their second year, but about one-quarter breed in their first year. There were relatively more grasses in samples obtained at higher zones. 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). Axis Deer. These coniferous trees were densely planted, and prevented understory growth (Takatsuki 1990a), which resulted in a low carrying capacity of the deer. 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. 2011, Tamura 2013). Through statistical methods, they determined that the "best pets" outside of dogs, cats, and other conventional pets are the sika deer, agile wallaby, Tamar wallaby, llama, and Asian palm civet. 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. When do deer shed their antlers? Reproduction Deer have 1-2 fawns annually, with twins being most common in does of prime breeding age. The proportions of grasses in SA 1 (23.5%) and SA 2 samples (33.2%, Kruskal–Wallis test, χ2 = 11.404, p = 0.003; Steel–Dwass test, t2 = –2.080, p = 0.094), and those in SA 2 and SA 3 samples (38.3%, t2 = –0.984, p = 0.587) were not different, although the proportion in SA 3 samples was significantly higher than in SA 1 samples (t2 = –3.413, p = 0.002). 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). They were analyzed using the Kjaldahl method (Kjeltec 2100 distillation unit). Sika deer are smaller than Virginia’s white-tailed deer, being a medium-sized member of the deer family. The estimated deer density at YT in 2015 was 50 deer km–2 from pellet counts (Nagano Prefecture 2016), which was 2–3 times higher than in 2005 (Yamanashi Prefecture 2017). Texas, Virginia, and Maryland’s Eastern Shore saw the first of the breed in the 1900s. The proportions of coniferous leaves in the feces were more at these subalpine sites than at other vegetational zones. Previous studies have suggested that although they are an exotic species, sika deer are not considered invasive because they do not directly compete with native wildlife for food and habitat. Sika deer are primarily found on Maryland’s lower Eastern Shore. 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. Other common foods of sika deer include poison ivy, catbrier, and marshgrass. Translations are not retained in our system. They eat what is easily accessible. You will have access to both the presentation and article (if available). Sika deer are known to feed most frequently on trees, shrubs, grasses, sedges, holly, conifers, fungi, acorns, bark, heather, and ivy. There have been two case studies on the variation in sika deer diet with elevation. PSs were compared among the three vegetational zones by the Kruskal–Wallis test with the Steel–Dwass post hoc test. More than 200 points were counted for each sample (YT: 200 ± 1, range: 200–203 counts, SA: 200 ± 1, range: 200–203). 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. 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. 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 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). Thus, there was no consistent seasonal change in fecal crude protein. However, the deer’s dependence on snacks given to them by tourists has been impacted by recent response to concerns over the coronavirus outbreak. Sika, rusa and sambar populations occur only in the North Island. The food habits of Sika deer (Cervus nippon) on Mt. 3), but only the difference between YT 2 (19.6%) and YT 1 samples was significant (10.4%, t2 = –3.105, p = 0.005). They are primarily nocturnal. This is simply because dwarf bamboos were abundant only at YT 1. In her fragile and panic-stricken state, Kristen was no longer so enthusiastic about feeding the sika deer of Nara deer park! Sika Deer in Maryland have Clement Henry to thank for their presence in the coastal state. The typical diet of the white-tailed deer does not remain constant all year long. The proportion of dicots in the samples obtained at high elevation seemed to be greater than those at low elevation in YT (Fig. The major findings of this analysis include the following seven points. Sika is Japanese for a small deer. Mating & Reproduction in Sika Deer In Europe the breeding season or rut for Cervus nippon takes place between September and November. 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. The specifics of what they will eat depends though on the region where they reside. One study in Omote-Nikko showed that the proportion of dwarf bamboo Sasa nipponica in sika diets varied with elevation (Takatsuki 1983). During mating season, males rapidly deplete their fat stores and may lose up to 30% of their body weight. Only fiber content increased from August to November in YT 3 samples (U = 11.0, p = 0.003). 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 Cervus nippon populations have been increasing on the Japanese archipelago. There is often a … Today, t… 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 sika deer varies in color from reddish-brown in the summer to dark brown or black in the winter. Sike deer have a varied diet, which they adapt to their environment. Since vegetation differs with elevation, it is expected that the food habits of sika deer would also differ by vegetational zone. They typically feed at night. However, during the intense Alaskan winters, they also feed on woody vegetation and lichens. Ohashi et al. Members of Bernina Alpine Club supported techniques of mountaineering. 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. This suggests that a decrease in snow induced by global warming may trigger sika deer expansion further into alpine zones. The sika deer is regarded as sacred in Japan. 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. 2009, Takii et al. In SA 3 samples, only fiber decreased from August to November (U = 2.728, p = 0.006). 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). The mean proportions of the major foods are shown in Fig. 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. This study assessed the composition of sika deer diets and compared nutritional quality between the low montane, subalpine and alpine zones. Sika deer consumed the same resources that comprised 78% of white-tailed deer diet. The vegetation is a deciduous broadleaved forest at SA 1 in the montane zone (SA 1, Fig. In fact, it is generally known that alpine plants are relatively high in nitrogen (Körner 1989). We analyzed sika deer fecal samples from Mt Yatsugatake (YT) and the Japanese South Alps (SA). 2012, Hashimoto and Fujiki 2014, Masuzawa 2015), and soil erosion has also been accelerated (Chubu Forest Management Office 2007). The Sika Deer feeds on a variety of woodland plants and grasses. 4) Our qualitative observations of habitats indicated that grasses were abundant in the alpine zone (Fig. In the presence of sika deer, white-tailed deer displayed an increased niche breadth (108%) and a lower diet quality (17%). Funding – This study was partly supported by Natural Parks Foundation (Volunteer Fund for Nature Conservation 2011). Females usually live in small groups with their young. The coastal forests here are poor in minerals, washed out by the continuous rain and snow. 2012), the results of this study are important for future alpine deer management. Sampling sites of sika deer feces in Mt Yatsugatake (YT 1–3) and the Japanese South Alps (SA 1–3). This will count as one of your downloads. Samples at YT 3 did not contain dwarf bamboo. You currently do not have any folders to save your paper to! The mean temperature in November at the foothill of YT ranges from –0.1°C in February to 24.8°C in August, and the mean annual precipitation is 1440 mm. 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. The Chesapeake Bay Program is a unique regional partnership that has led and directed the restoration of the Chesapeake Bay since 1983. Error bars indicate SD. When alarmed, adult males emit a distinctive, high-pitched “bark" to alert others to danger. A male sika deer will mate with multiple females over a breeding season, gathering as many as 12 females on his territory each year. 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. 2000, Igota et al. 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. They are also called sika elk or Asian elk. 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. Statistical standard (α) was set at 0.05. 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). 5). Crude protein contents were higher at higher zones (15–20%) than at lower zones (8–12%) in both study areas. Although they are called deer, sika deer are actually a member of the elk family. Their diet fluctuates all year to what is available each season. Some of the common types of food that they are known to eat include grass, leaves, shoots, and twigs. Of course, feeding deer during the winter is more of a challenge. 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. 5 (Supplementary material Appendix 1 Table A2). Cervus (Latin) a stag, deer. Some studies focusing on the foods of alpine ungulates provide evidence for the protein benefits of alpine vegetation. 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). Some populations of sika deer are seasonal migrants (Takatsuki et al. * p < 0.05, ** p < 0.01, *** p < 0.001, NS: not significant. The ecological niche occupied by sika deer is similar to whitetail deer and red deer allowing for chances to hybridize. Red deer is the most widespread species, and is also the most commonly farmed deer. 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).

This is the first study to indicate that grasses are an important constituent of the diets of alpine sika deer in Japan. akaishimontanum. There were more dicots in SA 2 samples (25.0%) than SA 3 samples (10.4%, t2 = 2.837, p = 0.013). 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. Dicots increased in YT 1 and SA 2 samples from August to November, but did not change at other sites. 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). Deer are herbivores and generally eat grass, nuts, twigs, alfalfa, corn, fruit, and fungi. 2009). However, some have been known to live up to 25 years in captivity. 3) Understories were dominated by conifers like Tsuga and Abies at YT2 and SA 2. 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 fully grown stags weigh between 40 to 70kg and hinds 30 to 45kgs. Despite these negative environmental factors, the alpine zone seems to provide high-quality forage. Sika deer are similar to Fallow deer in coat colour. 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). 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). 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. 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). Sika deer are native to Japan, Taiwan and eastern Asia, and were introduced into the Chesapeake Bay watershed 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. 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). However, their antlers and sharp hooves can also be used in defense. 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. Furthermore, alpine weather is unstable and may become cold even in summer. A. Ohtsu and S. Yamamoto helped the analysis. Get the latest updates on our work delivered to your inbox. There were more grasses in samples obtained at higher elevation. Diet: Sika deer primarily feed at dusk through dawn on marsh vegetation, grasses and agricultural crops such as corn and soybeans. Prof. T. Iriki at Azabu University advised the analysis of crude protein contents. He released 5 or 6 deer onto James Island over a century ago, which eventually led to the proliferation of the species in the United States. They are spotted as both fawns and adults (in summer), whereas white-tails are spotted only as fawns. 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). 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. 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). Sika deer may be quite small- to medium-sized, depending on the region where they live and the food sources they have available. The principal winter food items of red and sika deer were Euonymus spp. We can help you reset your password using the email address linked to your BioOne Complete account. 4). Create a new folder below. We randomly walked in the forests and shrubs, and collected fresh pellets (n = 20) from fecal piles (n = 10). Sika deer prefer to live in wetlands and forested marshes with dense undergrowth. Diet Sitka deer primarily eat green vegetation.

Above, a sika deer feeds on grass at the Chesapeake Bay Foundation’s Karen Noonan Center in Dorchester County, Md., on Aug. 2, 2017. The estimated deer density of SA in 2015 was 13 deer km–2 from pellet counts (Nagano Prefecture 2016), which was three times higher than in 2005 (Yamanashi Prefecture 2017). (Photo courtesy Peter Joseph/iNaturalist CC BY-NC-ND), Two sika deer feed on grass at the Chesapeake Bay Foundation’s Karen Noonan Center in Dorchester County, Md., on Aug. 2, 2017. Breeding occurs in autumn, beginning in late September. There was significantly less fiber in SA 3 samples (9.1%) than SA 1 samples (11.9%, Kruskal–Wallis test, χ2 = 4.751, p = 0.093; Steel–Dwass test, t2 = 2.431, p = 0.040). Sika deer not only excert effects on plants but also on abundance of birds (Okuda et al. 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. 1). Choosing hunting areas that provide some of these food sources may aid your hunting success. 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. 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). Supplementary material (available online as Appendix wlb-00710 at < www.wildlifebiology.org/appendix/wlb-00710>). 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. Location map of Mt Yatsugatake (YT) and the Japanese South Alps (SA). 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). Sika Deer are very opportunistic when it comes to the foods they eat. Sika deer have a white rump and white spots on their back. By comparison, an average adult man in Britain is 1.77m high and weighs 79kg. 6) Dwarf pine abundantly grew at the alpine zones (YT 3, SA 3), but coniferous leaves accounted only less than 2% (in August, 1.4% at SA 3, 0.4% at SA 3; in November, 1/8% at YT 3, 0.3% at SA 3) in the deer feces. The importance of good tasting deer meat lies more with the meat preparation then with the specie of deer. The mother nurses her newborn calf for up to 10 months on increasingly fatty milk. Our results seem to support these former studies. 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). Predators Wolf, black and brown bears. 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 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). Since little is known regarding the effects of deer grazing in the alpine zone of central Japan (but see Nagaike 2012, Watanabe et al. Privacy Policy, Chesapeake Bay Program 2007, Takatsuki 2009a, Otsu et al. 3.0, 2018). 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. An institutional or society member subscription is required to view non-Open Access content. 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. 3), but significant difference was found only between YT 1 and YT 3 (Kruskal–Wallis test, χ2 = 6.636, p = 0.036; Steel–Dwass test, t2 = –2.575, p = 0.027) and others were not significantly different (YT 1–YT 2: t2 = –1.853, p = 0.153, YT 2–YT 3: t2 = 0.379, p = 0.924). 2012).
