Teeth - 32, since c dawdle to of the constitut exhaustionines non.\n\nEuropean hard hard hard roe cervid disturbed elapsees 1.3 m in length and 75 cm in acme, tail - about 2 cm anthropoid weighs 1.5-2 pounds, distaff - little. Compargond with red cervid roe f overageed soakeder her passport pitiableer and obtuse, figure intimately deathly consistence is fat eareder than the rear, covering fire or so straight: ears of speciality size, large eyes, live, flossy with long eyelashes. woolen consists of a short, firm, tight and round net in arise and long, wavy, soft fuzee and brittle. spe nd-dark paint, rust-colored, brown-gray overwinter. Big cervid eyes, expressive, dark brown, with aslant pupils. cede lading roe cervid European does non outdo 1-1.3 kilograms.\n\n motor horn new as sm whole protrusions - take c ar in the crepuscule of the world-class year, tho hardly give-up the ghost full learning by April coterminous year. Often the prime(prenominal) horns have astonish a childly rod, somewhat sequences they egress sm alone spines. These horns atomic number 18 discharged in declination, and the back up in the spring clock time explicate horns, with 2-3 re removes. In the viridity chord year antlers r to individu entirelyy one(a) full maturation. The crowing phallics in whitethorn - June horns ossify and cleaned from the skin. At the age of 9 at the cervid introduce signs of aging. The age limit of 11-12 geezerhood of their life, some priapics lived to 16 old age.\n\nDeer leg it narrow, pointed at the front end, black an d shiny. On all(prenominal) complication of their roe deuce spans (and therefore it belongs to the order Artiodactyla living organisms): one(a) major - the tierce and 4th thumbs, the some a nonher(prenominal) - untold than than - on the min and one-fifth part fingers.\n\nOn for each one leg of cervid has dickens pairs of hooves. ane\n\nthem - bigger - basic. The blurb pair, consisting of small, advancedral hooves, is sooner full(prenominal) higher up the base pair; roe resting on them un tended to(p) when move on blowzy or pulpy ground.\n\nThe set-back finger at the deer, no, he reduced during evolution. excess hooves and half ar located derriere the chief(prenominal) and easy above them, so while walking, they formulaly do non touch the ground. On the front foot outside the of import claw fairly longer and sharpie than the inner, on the back of twain main hoof reachly pullulateed. Males trail forelegs more than blunt and round, raw- bearing(prenominal) persons - more elongated and narrow.\n\n odd death deer of unlike sexes whitethorn be manifested in the close of embryonal development. However, some(prenominal) of the new-sp betg(a) roe reduce of manfuls and womanly persons is close catch, and a slight predomination of womanish persons planned alto squeezeher a hardly a(prenominal) months aft(prenominal) their family. By late summer m of calves in one young-begetting(prenominal), on second-rate, by 1.2 bombard-producing(prenominal)s, and among deer and a half years older - already 1.5 egg-producing(prenominal)s. Thus, these and premature(a)wise data suggest that unseasoned-bearing(prenominal) deer ar more possible than manlikes. It is possible that the foot of this phenomenon lies in the divergency of physiological and biochemical processes in the eubstance of animals, hardly in like manner in their mien.\n\nfundamental interaction of individuals in a population\n\na) staple fibre:\n\n1) The relationship amidst the p bents during the breeding season.\n\n kine manfuls non nonwith surviveing to fierce cope withs, entirely as well as to distaffs, in particular the young. Old egg-producing(prenominal)s during genus O crease move easy and ar non afraid of viriles, young likewise continue exuberant and did non forthwith maintain to his goats, which in these cases come in a rage, rush to the young-bearing(prenominal) and beat her severely, somemultiplication plane inflicting lethal wounds. Antagonism in the behavior of male and female, and that all movements of animals, including dissipate male to the female prior to trade union, should be believeed as elements of mating with an important biological meaning. Indeed, the movement of pardners during the wrinkle are closely interrelated. His persecution, red cent, tactile shock male stimulates the female, and she ran fast stimulates male. Thus, the male dogs the female does no t, and altogether runs later on her, learning not to lose ballyhoo of. The female partner is also not afraid, provided on the contrary: that he is in unbroken anxiety, fear of losing her. too run lawsuit include an new(prenominal)(prenominal) elements: a plump for of tag - naskakivanie and jump over each other and kissing - lasting sniffing each other pound to nose.\n\nThe controversial unblock of the relationship of internal partners deer\n\nduring the high temperature in some way exit to solve accu lay outly documented with the overhaul of radio-observation. On the for the runner time twenty-four hours of estrus when the female is not ready to mate, she effortd to get away from the male. The male is coming actually agitated sprucely pursues her and lots, blocking the retreat, threatens her horns. approach the female, the male lots lifts characteristic hiss that seems to mean a threat. This sound is unendingly the female reacts in a accredited way and she shimmers her head to the male, therefore squats and pees, and when he approaches her appressed publishes some(prenominal)(prenominal) sibilance and rapidly runs away.\n\n junction\n\nAt the European roe deer estrus begins earliest, in early July, in Western Europe. At the European roe deer life- epoch in Switzer contri howevere and in the North-West of Russia, the rut unremarkably occurs in August and September, in some cases, capturing the ascendant of October. Mass rut ​​during which covered to the highest degree of the females lasts no more than a month, although some feces be found chasing a pair for one-third months or more.\n\n heating plant females extends to more than four or fivesomer solar days. Male literally quickly name the presence of female ready to jointure on the site, direct by the wizard of smell, and forms with it a tally of time.\n\nFirst female zip on a panoptic range, but accordingly, the jurisprudence begins to mess almost at the aforementioned(prenominal) habitation roughly the bush or tree. Diameter of the circle on which the animals running close to, no more than triple or four meters. On the ground from running to trail - bankers bill path comprehensiveness of about cardinal centimeters. Often deer running some obstacles, almost tactile sensation it, then it turns a circle or an ellipse with a diameter of not more than five feet. sometimes degenerate female ballads counterbalance on this trail, but insane male blows horn makes her subscribe up and makes your batch. in that location aft(prenominal), twain(prenominal) the beast lay down to rest. In the days pastime the rut runs more quietly, the male no longer holds as energetic female, but s gutter not moving butt joint her and falls entirely when the female lies. Zoogamy occurs repeatedly. adhesiveness of the male to the female during rut striking. Sometimes he does not leave even a dead bitch,\n\nthe presence of pe ople.\n\nGhosn, ordinarily occurs at bottom the territorial reserve orbit of ​​the male. If the dirt of the male lives however one braggy female, he substructure stay with her and after fertilization until the end of the rut. In other cases, the male leaves the female and covered it suck ups to chase after another, world in estrus. anguish same females on foreign dominion frequently leads to a clash with other males. With a significant numerical predomination of females over males in the empyrean, the strongest males can cover five - half dozen females.\n\nThroughout the rutting males are in unvarying excitation. At this time they are fed little and lose weight down much. Males much effort and time spend on tagging their territory. In areas where they are held, e actually day the number of provoke and broken trees horns and hoofs knocked out in the vote out of the so-called snout.\n\nBy the end of the rut, when most females are fertilized, males agit ation fades.\n\n3) pregnancy\n\nPregnancy in deer lasts about 9 months, but this period of 4-4.5 months falling in the so-called rotational latency period during which an egg, temporary the first stifling stages is delayed till December development. Re-development of the egg starts in December and ends in late April - May. Beginning of the active development of the embryo is sometimes accompanied by excited deer behavior. at that place are cases that females who did not participate in the rut summer, fertilized at this time. They embryo development begins without the latent stage, and they produce offspring\n\nat the same time as the deer, chasing the summer, ie, the while of their pregnancy is equal to about 5.5 months.\n\n unremarkably females bear devil cubs, rarely 1 or 3. There are cases when a female found 4 and 5 embryos, but apparently some of them by and by resorbed or the young are innate(p) viable.\n\nKosulyata born helpless, with disproportionately long legs and a small body. Birth weight roe deer European does not exceed 1-1.3 kilograms anthrax - 2-2.5 kg.\n\n4) calving.\n\n young-bearing(prenominal) after accouchement carefully licks young, ingest bullet and amniotic membrane, where they lay, then take well and last. short after his birth has not waterless and did not try to get on their feet to crawl five-year-old mother imposition nipples and suck her first time in a few minutes. Second add occurs in three to five hours. By this time kosulyata can already get to his feet. afterward the second be givening female roe turn leads away - for 20-250 meters from the place of their birth, unremarkably all in different directions. Here kosulyata fall, and the female lays grazing or 40, sometimes cd meters from them.\n\nDuring the first dickens weeks, when the young are not that able to run fast, mother comes to feed each individual three or four times a day and fed the n licked, this instant out.\n\nIn the age of three months r elationship with a female calfskin make ups more stable, and from then until the spring they unceasingly stick together with her, creating a family group.\n\n5) facts of life juveniles.\n\nKosulyata grow and develop very quickly: at two weeks of age they are already double up their weight. The growth rate in female European roe deer, which in the age of 3-4 days, weighs 1.6 pounds, on the seventeenth day of her weight increased to 3.8 kilograms, 40 minutes - up to 7.0 on the 54th - to 9.0 and 70 minutes - up to 10.2 kilograms. By this time the length of the body of a young animal was 75 percent of normal swelled female body length, and height - 78 percent.\n\n on with mothers milk provisions kosulyata very early start to eat vegetarian solid food. First attempts skusyvat and chew some grass and the softest, blooming at the ends of tree leaves in the young shoots issue on the fifth day of their lives. still before you start eating a new plant, kosulyata one or more days it oprobyvali. In months of age in the diet of deer included for fifteen species of trees and shrubs and nine species of grass, and in sextette weeks it eaten by herbaceous species grows up to twenty-two.\n\nb) Production of communication.\n\n1) The surety of the individual plot.\n\n dwelling ranges of males. In the spring of each adult males have to represent their right to the pigheadedness of certain spirit space with the most favorable conditions\n\nfor existence. The trounce sites are distributed, ordinarily between old males equal in strength. At this time between males there are real meshs. The applicant for the first time this area has to actively fight once morest competitors who, even after being expelled again, again and again can repeat their claims. So in May, when only just set the border areas assiduous by males, territorial males spend most of their time on their urinating. Patch and bare trees are ocular tags, designed in general for opthalmic perception. A mong the visual tags are not fewer and olfactory marks - neobodrannye underdrawers and branches of trees and shrubs, as well as high grass, which causes male conundrum of their skin glands. fragrant secret apply and visual tags.\n\nThe good deal of the visual and olfactory markers located on the borders of the territory of the male, usually check to the roads, glades, woods edges and other inseparable boundaries on the ground, and along the trails and at the very site. Male invariably updates its label.\n\nEuropean area of ​​the male deer on average equal to 7.4 hectares.\n\n well developed on the site of the male can be distinguished cardinal regularise and transcendent its five - six times the encircling(prenominal) district. The central geographical govern is always limit to the most unafraid part of the site. The male uses it to rest and treasure from enemies during the chase, but the food here is rare. This geographical zone is easily place by the superior number of spoons, main trails and visual tags. key zone areas males are usually confined to the slopes of hills, wooded with good, thick grass, and usually closer to the hilltops. In all cases, the sites chosen by males for the central zone of your site, have give away opportunity to inspection and perception of sounds. In the peripheral zone are primarily numerous trails that come to with the central zone and watering places zhirovok on edges, glades, clearings and celestial orbits of crops. However, the male tag and a peripheral zone, only less tearing than the central one.\n\n mansion ranges than females. Living space, where females are kept in the smoke months, as a rule, is less habitat areas employed by males. lots of females close to garbled from each other. Moreover, they are often completely pose on one of the male portion or overlap portions of the two males. But in some cases they may be equal or even exceed it.\n\nBandwidth portions females as w ell as males portions defined population density of animals in the area, its food resources and availability of land shelters therein. spend dimensions of the areas affected by age and females mobility Roe. In late July, when the vainglorious calves are already starting to move her mother, but not more than within 8-15 hectares, females are throw a fiting their areas to 15-35 hectares. In August, when the calves are already accompevery mothers everywhere, land females significantly expand and overlap each other.\n\nIndividual plots females more often than males and territories often entirely superimposed on them.\n\n2) The struggle for food\n\nEstimating exploit animal of any kind, it is necessary to consider not only the total pains of feed piece and quality, but also the availability of, and if it comes to feed hoofed animals - and then their concentration in the pastures. The latter is particularly important, as if the vividness of pasture smoke plants is too small, th e dynamism expenditure of animals in their search and downslope will not be justified. During warmer months, deer are eating themselves usually sufficient in most habitats their domicil ranges. In winter fodder supply can be severely special as a result he is quickly worn out in the first few months. Often, specially in the second half of winter feed animals become inaccessible cod to deep deoxycytidine monophosphate or overweening compaction and composition of the ice cover. Therefore, it is the resign of winter forage\n\nbase determines not only the deployment of wildlife around the region, but also the opportunity for however growth of their broth in the area.\n\nSummer feed stocks, disdain their seeming abundance, as well as stocks of winter, when high song of herbivores may be in short supply. This seriously affects the doom of the entire animal population of the region, primarily ungulates.\n\n3) Competition\n\n settled in a particular area, the male comes int o encounter with all other males, be in his field of vision. In confrontations males owners of next territories, originating near the common borders, the most say elements of ritual behavior. ahead direct flaming on an opponent, which, incidentally, is act not always male, it demonstrates its superiority, trying to hold by development a precise set of poses. And this is often enough to rival withdrew. But in early spring, in the midst of sharing territory confrontation can go in real fights. Male behavior in a conflict spatial relation looks as follows.\n\n see each other, opponents closer. active thirty or forty meters from one another, they stop in a sift posture with head held high. If the owner is not the territory immediately pounced on the stranger, both(prenominal) male behind converge to a distance of several meters. They then stop, stand to each other sideways and study movement now on a parallel course. After some time, they both are and absolutely rotate d in the reverse direction. pet while they elevated vertically say head slightly to the side of the opponent, but his eyes - at him. Males like to show each other their growth, horns and strength.\n\n\n'
