The effect of temperature on turtle breeding
The environmental conditions affecting the life of lice include climate factors and soil factors. The climatic factors that affect the life of lice include temperature, humidity, light, ventilation, etc., but the basic role is temperature and humidity. Various climatic factors directly or indirectly affect the development speed, reproductive rate, survival rate, and behavior of scorpions. Changes in the development cycle and population are the necessary conditions for their lives. 1 . Temperature tweezers belong to a temperature-changing animal. The source of thermal energy required for their life activities is mainly the radiant heat of the sun, followed by the heat energy generated by their own metabolism, but it depends to a large extent on the temperature of the surrounding environment. (1) Crab's adaptation to temperature 1 temperature zone. Also known as the effective temperature zone. Gas life activities in this area can be normal. However, the speed of its development is different, so it can be divided into the following three temperature zones. l) High temperature zone: In this temperature zone, the growth rate of Zongzi slows as the temperature increases. The upper limit of this temperature zone is called the maximum effective temperature. At this temperature, the fertility of the scorpion will be inhibited. 2) The optimum temperature zone: In this temperature zone, the development speed of Scorpion is appropriate, and it accelerates with the increase of temperature, with moderate life span and maximum fertility. 3) Low temperature zone: In this temperature zone, the developmental speed of the gardenia will slow down as the temperature decreases, and the fertility will also decline, and even it will not breed. The lower limit of this temperature zone is called the minimum effective temperature. Only above this temperature, the wolfberry begins to develop, so it is called the development starting temperature. 2 critical high temperature zone. In this temperature zone, due to the unfavorable high temperature, the growth and reproduction of the gardenia are significantly inhibited. If the high temperature lasts for a long time, the lice become a hot coma or die; if the temperature returns to normal within a short time, the lice can return to normal, but some functions may be damaged, especially the most sensitive reproductive function. The death of lice depends on the intensity and duration of the heat. 3 lethal high temperature area. In this warm area, the cricket died after a short time. The upper limit temperature is called the highest lethal temperature, which is the theoretical maximum lethal temperature. 4 critical lethal low temperature area. In this warm area, the scorpions are in a cold coma. If the duration is short, the tweezers can return to normal when the temperature returns to normal. If the duration is too long, it can also cause death. The death of lice depends on the intensity and duration of the cold. 5 Lethal temperature area. In this temperature zone, lice usually dies after a certain period of time. The lower limit temperature is called the lowest lethal temperature, which is the theoretical maximum lethal temperature. The different developmental stages and different physiological ecology (such as growth and dormancy period) of wolfberry fruit, under different environmental conditions (such as season, location, rate of change of outside temperature, etc.), the adaptation range of temperature is different. The adaptability of lice to changes in the ambient temperature is also known as the temperature ecological plasticity of the lice. (2) The temperature requirement of the gardenia The growth, development and reproduction of the gardenia are closely related to the temperature. As the temperature drops below 10 °C, the wolfberry does not move much. The temperature is lower than 20 °C, and the activity of the wolfberry is less. The optimum temperature for the growth is between 26 and 38 °C. The temperature is between 35 and 38 °C. The scorpion is the most active, and the growth and development are accelerated. The litter size and mating are mostly within this temperature range. When the temperature exceeds 41 °C, the water in the body of the cockroach is evaporated. If the temperature is not cooled in time, and the water is not added in time, the cocoon is prone to dehydration and death. When the temperature exceeds 43 °C, the scorpions will soon die. The effects of high and low temperatures on the survival of lice. High and low temperatures have a great influence on the survival of lice, and they are one of the important environmental factors for the variation of lice population. 1 High temperature and heat resistance. When the scorpion enters the high temperature lethal temperature zone, it dies after a short time. The scorpions usually die quickly when the temperature exceeds 43 °C, but the deaths and temperatures are different due to the type and living environment. In addition, the endurance of the same species of scorpion is different at different stages of development. High temperature can inhibit the development of scorpion, make it lose weight, increase mortality, and there are some residual effects, especially the impact of adult lice, or cause hypoplasia, infertility, or inhibition of gonadal development, infertility eggs Increase in quantity and so on. The main reasons for the death caused by high temperatures are: l) Temperature rise causes excessive evaporation of water in the body and causes death of lice. However, in the natural world, this situation is more complicated. In addition to being affected by high temperature intensity, duration, body wall water retention mechanism, etc., it is also closely related to the environmental humidity. 2) High temperature causes the body's protein to coagulate, denature and die. The protein denaturation temperature is related to the water content. When the protein has a large amount of water, the denaturation temperature is low; when the water content is low, the denaturation temperature is high. 3) At high temperatures, high temperatures can destroy the mitochondria of cells; inhibit the activity of enzymes and hormones; high temperatures accelerate the inconsistency of physiological processes to some extent, such as not supplying enough oxygen and not excreting more metabolism. The product causes poisoning and causes paralysis of the nervous system. 2 Low temperature and cold resistance. The safety temperature of wolfberry winter wolfberry is 1 to 3 °C. If it falls to 0 to 2 °C, it will be frozen and dying within half a month. Scorpions will die within a certain period of time in the cold temperature zone. However, the cold tolerance of wolfberry is stronger than that of heat resistance, that is, the ability of wolfberry to endure low temperature strength and duration is relatively strong. This is mainly because the body fluid of wolfberry fruit contains a large amount of sugar, fat, protein and other chemical substances, and forms a certain organic structure with the protoplasm so that the body fluid can tolerate a certain low temperature below 0° C. without freezing. Different types of scorpions, different developmental stages of the same species of scorpion, physiological conditions in the body, living conditions (different seasons), and the speed of cooling can all affect the level of the supercooling point of the scorpion. For example, the accumulation of body fat, sugar, and the decrease of free water and the increase of bound water in the dumplings can all increase the temperature of the freezing point and the supercooling point and enhance the cold resistance. Therefore, the degree of cold tolerance is an important indicator of cold tolerance. The cause of death due to cold temperature is different due to the type of lice and the low temperature intensity and duration. In general, there are two cases. First, at low temperatures (eg, around 0°C and above), some cold-tolerant scorpions gradually consume nutrients in the body, become weak, and become physically unbalanced, failing to recover and die within a relatively long period of time. . The second is that the temperature below 0 °C is very low, the main cause of mortality is the body fluid freezing mechanical damage and protoplasmic degeneration, some of the hardy species are mostly such a situation. (4) Effect of Temperature on the Reproduction of Scorpion Scorpion reproduction also requires a certain range of appropriate temperature, but this range is narrower than the optimal temperature range for growth and development, and is generally close to the optimum temperature range for the growth and development of Scorpion scorpion. Within this range, the fertility of the scorpion increases with increasing temperature. 30 ~ 41 °C is most suitable for fertilization and embryonic development in females, 27 to 38 °C is best for litter size, 20 to 24 °C for no litter size, and 25 to 36 °C is best for males. Although the adults of Scorpion can survive at lower temperatures and have a longer lifespan, their gonads are not mature enough to mating, spawning, or spawning, but mostly infertile eggs; at too high temperatures, adult lifespan Short, especially male sperm is not easy to develop, or lose its vitality, but also affect the mating behavior, causing the eggs laid by females to be mostly unfertilized eggs.
