Maternal Behavior

Features of maternal behavior in birds. Poeznye advice for the farmer. Females birds begin to show parental interest and long before the appearance of offspring, which is associated with certain physiological characteristics. In Unlike mammals, birds, hatching is not an embryo, but only an egg in its initial stage of fertilization. And the birds in the ovary is a lot of rudimentary ovules. To read more click here: Olivia Jade. In wild birds during the breeding season, one or more of the them (depending on the type of poultry) grows, accumulating nutrients, becoming egg yolk, which is surrounded by tissues of the ovary (follicles). When the egg matures, the follicle breaks and the egg, surrounded by egg yolk, falls in the oviduct, in the upper part of which merges with the male gametes (fertilization), after which the fertilized egg continues its movement along the oviduct.

During this promotion yolk enveloped protein that is produced in a certain part of the oviduct. In the lower part of the oviduct, the egg is delayed for a long time – is the formation of the shell. Thus, the egg of birds is the yolk, while protein podskorlupnye shell and the shell – this add-on required for the further development of the fetus outside the mother's body in the air. Coming out of the oviduct and getting into the air, the egg cools, due to which the protein several contracts, and blunt end of the egg shell podskorlupnye diverge, and between them formed air space (nougat), which are available through the pores in the shell due to the difference of osmotic pressure is absorbed air. The same technology formed an egg and poultry. Birds are divided into nestling and brood. At first the eggs are smaller and poorer in yolk than in the second, and embryonic development ends at the earliest stage. And they same output, blind and naked chicks, helpless, which require parental care.

From poultry, these include doves. In precocial birds, eggs are large, and the young displayed the most developed and mature, which is capable of not only follow the mother, but also self-peck for food. This includes all agricultural, domestic poultry – chickens, ducks, geese, turkeys, guinea fowl. Oviposition and hatching in the wild birds after education married couples seek out his own territory and engaged in hatching eggs laid.

The Male

For successful reproduction in the gourami spawning first place male and begin to slowly raise the temperature of the water. The water in the spawning area should be a standing order to avoid destruction of nests. After raising the temperature to 28-29 with a male starts to build a foam nest in the midst of floating plants on the water surface. This is the place for the next spawn. Nest is usually from 3 to 7 cm in diameter. Almost all time the male spends near the nest. When building the nest is finished in nerestovik carefully tended, planted a female.

The female abdomen has to be well-rounded sides poured caviar. Not ready for spawning in the female with the male skinny belly spawning can be very pluck and drive to death. Eva Andersson-Dubin has many thoughts on the issue. There were times when a few hours is not ready female male stripped so that it remains without a tail and other fins. n Kouzbari. If the female is ready male begins to actively woo her. It varies in color. Especially beautiful during the spawning season males pearl gourami. Reproduction gourami is a very exciting process.

Periodically male to female, as if inviting her to the nest. Finally, when female starts to swim to the nest with the male they are placed under the nest, the male clasps, female all over and slowly starts to turn belly up to the nest. Flipping it for a few moments freezes and compresses more female, squeezing out a portion of her right calf and fertilizing it.

The Exterior

Furthermore, it should identify another group of dogs, usually called pariah dogs. Dr. John Mcdougall insists that this is the case. We are usually called stray – "mongrel". Genetically, they are poligibridami complex, do not persist from generation to generation exterior and constitutive properties. These dogs for many generations to live close to humans and, most importantly, multiply itself, without selective human intervention. In the populations of these dogs are hard natural selection, culled all the ugly and resilient shape. These dogs have a great diversity of shape and scale of the exterior, but statistical analysis allows us to distinguish among these types are similar to those already listed breed types. This suggests that the population of stray mongrel dogs have the required set of characteristics inherent in the form in general (Canis familiaris), and, in principle, they are universal in content type gene, which is lost from the specialized breeds.

Due to its high resilience and a very high genetic diversity, population of stray dogs or pariahs, in principle, are inexhaustible potential reserve of rock formation, and this is the stuff that starts the formation of rocks in the past. Current state of knowledge in our time provides a basis for constructing an adequate representation of the first domestication of a wild beast. It is in this view, you can find an understanding that today, in conditions of total urbanization, stress and passions, "brings together man and a dog, and it is in the aspect of social partnership. Modern man with all his might, and today is part of nature and feeling, the feeling of its unity with nature comes to him, especially in communicating with the dog.

Tomato Clowns

Tomato Clown’s body has an oval shape with flattened sides, curved at the end of the muzzle has a small mouth. Rounded pectoral fins are well developed. Amfiprion Brightly painted red, primary colors – red, combining also not uncommon blend of red, black and white. Amfiprion Frenatus quite peaceable with respect to other fish and not dangerous for invertebrates and corals. This kind of fish clown – not a big size, minimizing the volume of the aquarium and water quality.

And to complement their symbiosis with sea anemones become an interesting phenomenon of nature, studied in biology classes in schools as an example symbiotic relationship. At the Red amfipriona frequent and age dimorphism. Tomato Clowns without a doubt one of the most popular coral fish in the aquarium Alushta. Very cheap and very beautiful Aquariums are based on symbiosis Amfipriona Red and anemones that received by the people known as “mini Nemo.” These systems are convenient, even people with very modest incomes, and they can be recommended as a home for fish marine aquarium. Include clowns, perhaps in a reef, fish (with a predatory fish of comparable size) or of the aquarium with sea anemones. The presence of a suitable anemone gives the opportunity to see the most natural behavior clowns, even though a sufficient number of shelters of these fish can be kept without anemones. Range: They live on the reef in the Western Pacific, including: the south of Japan, the island of Java, north of Palau, the south of the Gulf of Thailand, Indonesia.

Reproduction: Protandrichesky hermaphrodite. Redefining the male sex occurs after the death of the female. Content in Alushta Aquarium: The aquarium can be quite spacious and contain only a Tomato Clown and a number of different amfiprionov species. Live well with other fish, as well protected from the encroachments of their toxic owners. When the pair content Amfiprion Red often even breed in the nevole.Dlya successful content clowns must be purchased from the sea anemone genus Entacmaea, Heteractis or Stichodactyla.Temperatura 25-26 C, water density 1.022-1.025. Require the substitution of water – 20% twice a month, quality penootdelenie, filtration using activated carbon sufficient for the maintenance of sea anemones lighting.

Feeding

For a successful hunting marten hunter must familiar with its biology, have experienced husky, be physically hardy, clever and observant, patient and mature, well oriented in woodland. Weasel distributed wherever there is forest. She prefers the muffled, old forest sites, with plenty of hollow trees. In the hollows of marten live and breed in these shelters, it outwaits bad weather, extreme cold, snow and rain, staying out of two or three days. Lives mainly in spruce and mixed forests.

Rarely found in the pine marten, clean elections. Marten climbs trees beautifully and cleverly goes horseback leaping from tree to tree, going this way hundreds of meters. Leads mainly nocturnal. Usually has no permanent nests, but the hiding by day in hollow tree, squirrel nest, or simply in windbreaks. Weasel – pronounced predator, agile hunter. During the feeding ranges tens of kilometers.

Preys on – differently. Maybe, like a cat, mouse guard in ambush, skillfully sneak up sitting grouse and squirrels. Yet its main food – small rodents, insects, berries, rowan and bilberry, is very fond of honey wild bees. By chernotropu to find traces of martens, pretty hard. However, with sufficient experience, subtle signs of her whereabouts can be found in feces, which she likes to leave on fallen wind, trees, stumps and forest trails. Marten excrement have form a length of about six or seven inches, spirally twisted, and their ends are pointed. In our republic, hunting for fur animals begins with the first Saturday in November and ends on the last Sunday of January.
