The functional load and adaptive significance of different muscle groups in the suckers themselves and the associated structures--preoral lip and muscular cap--are discussed. Complete section series in three projections have been examined; this demonstrates the presence of previously unnoticed structures, namely, semicircular and diagonal muscles, regulating shape of the oral cavity, and short longitudinal muscles, acting as a sphincter, as well as localization of the largest internal muscles on the sucker lateral sides. It has been shown that the presence of internal longitudinal muscles suggests that the organs in question are closer to the oral suckers of other trematodes rather than to their pharynxes.</p>","PeriodicalId":77187,"journal":{"name":"Izvestiia Akademii nauk.

It is noted that the percent of graminoids has increased considerably and the proportion of forbs has decreased in the vegetation of current pastures, which has had a negative impact on the nutrition and state of saigas. It is shown that the lower nutritional value of graminoids has caused a decrease in the digestibility of forage used by saigas and does not provide the physiological requirements of the animals. It is established that modern steppe pastures, where gramineous communities prevail, are of little use or absolutely unsuitable for the stable existence of saiga populations. Only separate dwelling places with an abundance of forbs continue to provide adequate nutrition for saigas and well-being for their local groupings.</p>","PeriodicalId":77187,"journal":{"name":"Izvestiia Akademii nauk.

The results of our analysis suggest that \"immunological stress\" induced by viral or bacterial infection, an unhealthy diet, and the mother's behavior during pregnancy and lactation are significant risk factors for the developing offspring. The brain is the key target for these factors. The continuous effect of stress stimuli during critical periods of brain development induces hyperactivity and increased response of hypothalamic-pituitary-adrenal system.
