What do Japanese macaques eat on Kinkazan?
They compete for some plants with Sika deer on Kinkazan Island, but when they climb trees to get the most energy sufficient leaves, in the process they knock down leaves, which the Sika deer eat. Japanese macaque serves as important prey species for mountain hawk-eagles, Japanese wolves, and raccoon dogs.
What is a Japanese macaque?
The Japanese macaque is a monkey of medium size. They are also called the snow monkey because they often live in snowy regions. They have long, thick fur, of a brown or grey color.
How often do macaques feed?
In colder areas, from autumn to early winter, macaques feed in between different activities. In the winter, macaques have two to four feeding bouts each day with fewer daily activities. In the spring and summer, they have two or three bouts of feeding daily. In warmer areas such as Yakushima, daily activities are more varied.
How do Japanese macaques respond to Coos?
During feeding or moving, Japanese macaques often emit "coos". These most likely serve to keep the troop together and strengthen social relations between females. Macaques usually respond to coos with coos of their own. Coos are also uttered before grooming along with "girney" calls. Variants of the "girney" call are made in different contexts.

How do Japanese Macaques live?
Japanese Macaques live together in troops that are led by the alpha male and usually consist of between 20 and 30 individuals. The alpha male not only helps to sire young, but also decides where the troop should go, and protects it from both predators and other Japanese Macaque troops. Social rank is very important in Japanese Macaque society, and consist of both males and females, with the male’s rank often determined by his age. Offspring however, are also thought to inherit the rank of their mother with younger siblings often outranking their older brothers and sisters. Japanese Macaques are incredibly sociable animals, particularly the females who tend to remain in the same troop for their whole lives, and spend their time together, grooming and raising the troop’s young.
What is the Japanese Macaque?
The Japanese Macaque is an omnivorous animal meaning that it forages for both plants and smaller animals in order to survive. Unlike a number of other Monkey species, Japanese Macaques are primarily ground-dwelling so the majority of their foraging is done on the ground.
Why do Japanese monkeys have thumbs?
Like other Monkey species, the Japanese Macaque has opposable thumbs, allowing it to grasp and hold objects and is able to walk on just its hind legs when it has something in its hands. The Japanese Macaque also has large pouches in its cheeks, to allow the Japanese Macaque to store food whilst foraging.
How many monkeys are killed in Japan?
Like many of the 22 Monkey species found across Japan, the Japanese Macaque is often loved and protected by the native people. However, growing Human settlements and land clearance for logging and agriculture has meant that Japanese Macaques have lost vast areas of their natural habitats, and often have to approach farmland in order to find better food supplies. It is estimated that, despite being a protected species in Japan today, around 5,000 Japanese Macaque individuals are killed every year by farmers who claim to be protecting their livestock and their crops. In the Nagano Mountains in central Japan though, the Japanese Macaques that bath in the hot springs, have become one of the country’s most desirable tourist attractions.
What is the temperature of Japanese macaques?
In the northern and central parts of Japan, Japanese Macaques have to contend with seasonal changes with temperatures ranging from -15 degrees Centigrade in the winter to more than 23 in the summer, where the vegetation primarily consists of deciduous trees and conifers.
What phylum do Japanese macaques belong to?

Why do Japanese macaques grow thicker?
Their thick, furry coat is usually grey or brown in colour, sometimes with a slightly mottled pattern, and grows thicker during the winter months to allow the Japanese Macaque to stay warm in freezing conditions.
How do Japanese macaques live?
Like other primates, the Japanese macaque likes to live in a social group called a troop and are diurnal, or awake during the day. Bunking on average with 40 other individuals, life for the Japanese macaques is centered around their social structure. Higher ranking males not only get first access to hot springs, but also to females during mating season. Unlike other mammals, like dogs or big cats, the macaques have small litters with only one or two babies. Mothers care extensively for their young, protecting them both from predators and other jealous males. However, the work isn't all just on Mom. Some male Japanese macaques care for their own offspring too, feeding them and carrying them.
What Is the Japanese Macaque?
Visiting an onsen, a natural hot spring bath, in Japan is a relaxing experience that must be tried. People of all ages relax in the warm water from hot springs in this volcanically active country. But humans aren't the only ones that enjoy a day at the spa. In the mountains of Nagano on the main island of Japan, the Japanese macaque can be seen relaxing in natural hot springs during snowy, winter months.
Why do macaques huddle together?
In macaque populations, as the temperature gets colder, more and more macaques huddle together to generate heat for the group.
How high can a Japanese macaque be found?
When the mountains aren't so cold, the Japanese macaque can be found at elevations over 3,000 meters. But when winter descends so do the macaques, retreating to warmer temperatures at the base of the mountains.
What are the behavioral adaptations of macaques?
One of their most notable behavioral adaptations is soaking in the hot, volcanic springs in the mountains. The warm springs help them to regulate their body temperatures in winter. However, the hot spring soak is reserved for only the highest ranking macaques in the group.
What is the temperature of snow monkeys?
Living on the southern islands of Japan (Honshu, Shikoku, and Kyushu), these primates endure brutally cold winters with temperatures diving down to -20 degrees Celsius. Known as 'snow monkeys' for good reason, these animals have unique adaptations to keep them warm.

Habitat. Japanese macaques inhabit subtropical and subalpine forests. In the northern part of their range, they inhabit cool temperate deciduous broadleaf forests. In this region, temperatures average 10.9 ˚C, and annual average rainfall totals 1500 mm. In the southern part of their native range, Japanese macaques live in evergreen broadleaf ...
Where are Japanese macaques found?
They are found on three southern main islands of Japan: Honshu, Shikoku, and Kyushu, as well as a few smaller islands. Japanese macaques also survive well outside of their natural range, as with one introduced population in Laredo, Texas.
Why are Japanese macaques so dangerous?
Increased predation on crops and presence near humans may be due to the reduction of natural habitat because of logging. Japanese macaques also carry similiar diseases to humans.
What are some altruistic behaviors of Japanese macaques?
Japanese macaques exhibit some altruistic behaviors, and most are observed between mothers and daughters. These behaviors include protection, support, food-sharing, and alarm calling when a predator is observed. They may also practice co-feeding, in which a dominant individual gives access of food to subordinate individuals. ( Belisle and Chapais, 2001; Fa and Lindburg, 1996; Hadhazy, 2010; Muroyama, 1991; Saito, 1996; Trivedi, 2009)
How big is a Japanese macaque skull?
The skull of provisioned Japanese macaques averages 134.4 mm in length for males and 118.1 mm for females. The skull of non-provisioned individuals are slightly reduced, averaging 129.5 mm in males and 115.8 mm in females.
How much does a female macaque weigh?
Females average 8.4 kg in weight and 52.3 cm in height. There also seems to be a correlation between the body weight of Japanese macaques and climate. Japanese macaques in southern areas generally weigh less than those in northern areas of higher elevations, where more snow is present during winter months.
Why do Japanese groom their macaques?
Social grooming is common among Japanese macaques. Grooming helps to remove parasites and also to create and maintain social bonds within the troop. Most grooming is performed between kin, usually mothers and daughters. Japanese solicit individuals to groom them by approaching an individual and presenting the neck, face, flank, or even rump. Adult females solicit individuals more often than immature offspring. Two different vocalizations are associated with grooming: one when they attempt to groom and one while soliciting grooming. ( Belisle and Chapais, 2001; Fa and Lindburg, 1996; Hadhazy, 2010; Muroyama, 1991; Saito, 1996; Trivedi, 2009)
What are the characteristics of a Japanese macaque?
Japanese macaques are predominantly quadrupedal and can be considered semi-terrestrial. Females spend more time in trees than males and males spend more time on the ground than females. Leaping is seen in the Japanese macaque, but suspension from supports is not common (Chatani 2003). Japanese macaques are excellent swimmers and are reportedly able to swim distances of over half a kilometer (Mito 1980 cited in Fooden & Aimi 2005). This macaque’s fur is a unique adaptation to cold, as fur thickness increases as habitat temperature decreases and allows the monkey to cope with winter temperatures as low as -20° C (-4° F) (Hori et al. 1977).
What are the two habitats of Japanese macaques?
Of the habitats of the Japanese macaque, the two most important are the warm temperate evergreen broadleaf forest and the cool temperate deciduous broadleaf forest (Fooden & Aimi 2005). In the northern deciduous forests, leaves are absent from the trees for up to 5 months of the year (Suzuki 1965).
How big are Japanese monkeys?
There is a degree of sexual dimorphism between male and female Japanese macaques with the males weighing somewhat more than the females and on average having a longer body length than the females. The average body weight of the Japanese monkey is 11.3 kg (24.91 lb) (M) and 8.4 kg (18.52 lb) (F) (Fooden & Aimi 2005). In addition, there appears to be a correlation between climate and body weight, as Japanese monkeys from northern colder areas weigh more than those from warmer areas of Japan (Hamada et al. 1996). Average body length for males is 570.1 mm (22.44 in) and for females is 522.8 mm (20.58 in) (Fooden & Aimi 2005). The tail is short, averaging 92.51 mm (3.64 in) in males and 79.08 mm (3.11 in) in females (Hamada et al. 1996). Longevity for males has been confirmed as long as 28 years and into the 32nd year of life for females (Fedigan 1991; Nakamichi et al. 1995; Fedigan & Pavelka 2001). Actual average lifespan, however, is significantly shorter; with wild females living for an average of just 6.3 years (Takahata et al. 1998).
Why is the Japanese macaque population expanding?
Within their range, the distribution of the Japanese macaque is expanding, at least partially as a result of the species losing their fear of humans, coupled with demographic and economic shifts in the Japanese human population (Watanabe & Muroyama 2005).
How long do Japanese macaques stay together?
This association between a male and a female Japanese macaque is characterized by a pair mating, feeding, resting, and traveling together, and lasts an average of 1.6 days during mating season (Huffman 1992). Over the course of a mating season, Japanese macaque females were observed to enter consortships with over 4 different males on average (Gouzoules & Goy 1983). Typically there is a correlation between male rank and consort duration, with higher-ranking males remaining in consortships longer than lower-ranking males (Huffman 1992). Higher-ranking males will interfere in the consortships of lower-ranking males in an attempt to disrupt them (Perloe 1992).
Where do macaques sleep?
Finally, in the spring and summer, there are two or three bouts of feeding per day (Yotsumoto 1976). The macaques typically sleep in trees but they also sleep on the ground, often on flat rocks and fallen trees or behind rocks or fallen trees (Wada & Tokida 1985 cited in Fooden & Aimi 2005; Takahashi 1997).
Where are Japanese macaques found?
The Japanese macaque is native to the islands of Japan. Of the four main Japanese islands, Hokkaido, Honshu, Shikoku, and Kyushu, Japanese macaques are found on all but Hokkaido, the northernmost (Fooden & Aimi 2005). Even though its range is restricted to the three southern main islands of Japan, the species nevertheless represents the northernmost wild populations of non-human primates in the world. The absolute northernmost Japanese macaque populations are found at the northern tip of the island of Honshu on the Shimokita peninsula (Izawa & Nishida 1963; Uehara 1975). These northern populations exhibit significant cold adaptation as northern Honshu can be snowbound for up to a third of the year (Izawa & Nishida 1963). Japanese macaques also inhabit several smaller islands near the coasts of Honshu, Shikoku, and Kyushu (Fooden & Aimi 2005).
How big are Japanese macaques?
The Japanese macaque is sexually dimorphic. Males weigh on average 11.3 kg (25 lb), while females average 8.4 kg (19 lb). Macaques from colder areas tend to weigh more than ones from warmer areas. The average height for males is 57.01 cm (22.44 in), while the females average height is 52.28 cm (20.58 in). The size of their brain is approximately 95 g (3.4 oz). Japanese macaques have short stumps for tails that average 92.51 mm (3.642 in) in males and 79.08 mm (3.113 in) in females. The macaque has a pinkish face and posterior. The rest of its body is covered in brown or greyish hair. The coat of the macaque is well-adapted to the cold and its thickness increases as temperatures decrease. The macaque can cope with temperatures as low as −20°C (−4°F).
What is the coat of a macaque?

How long do macaques mate?
Macaques mating. A male and female macaque form a pair bond and mate, feed, rest, and travel together, and this typically lasts 16 days on average during the mating season. Females enter into consortships with an average of four males a season. Higher-ranking males have longer consortships than their subordinates.
How do macaques give birth?
Macaques usually give birth on the ground. Infants are born with dark-brown hair. They consume their first solid food at five to six weeks old, and can forage independently from their mothers by seven weeks. A mother carries her infant on her belly for its first four weeks. After this time, the mother carries her infant on her back, as well. Infants continue to be carried past a year. A mother and her infant tend to avoid other troop members, and the mother may socialize again very slowly. However, alloparenting has been observed, usually by females which have not had infants of their own. Male care of infants occurs in some groups, but not in others; usually, older males protect, groom, and carry an infant as a female would.
How do macaques signal when they are ready to mate?
Macaques signal when they are ready to mate by looking backward over a shoulder, staying still, or walking backwards towards their potential partner. A female emits a "squawk", "squeak", or produces an atonal "cackle" during copulation. Males have no copulatory vocalizations. Mother macaque with infant.

Do Japanese maples need wet soil?
The placement of your tree will determine how attractive and lush it will look and even how long it will live. Japanese maples require well-draining soil and will do poorly in clay or wet soil. Most of the trees thrive in a site that gets some sun in the morning but shade in the afternoon.
Can a Japanese maple tree survive in hot sun?
Both strong winds and hot sun can stress or even kill a maple. Maple species are understory plants in the wild, and excess sun can be very wounding to your tree. Protect your tree at least until it has established a mature root system. Fertilizing Japanese maples is an important part of the nurturing process.
