Генетико-эпидемиологическое обследование населения республики Северная Осетия-Алания проводится сотрудниками лаборатории генетической эпидемиологии ФГБНУ «МГНЦ». В рамках стандартного протокола исследования проводится изучение максимально возможного числа популяционно-генетических характеристик. На основании 27583 брачных записей проанализированы индекс эндогамии, интенсивность метисации и этническая брачная ассортативность в 8 районах Северной Осетии и г. Владикавказе. Выявлены различия этих брачно-миграционных характеристик между двумя субэтносами - иронцами и дигорцами. Дигорцы характеризуются более высокой эндогамностью и более низкой метисацией, чем иронцы. Genetic epidemiological study of the population of the North Ossetia-Alania Republic, Russia, is caring out by the Laboratory of Genetiс Epidemiology of Research Centre for Medical Genetics (Moscow, Russia).Within the framework of the standard protocol we study the maximum of possible population-genetic characteristics. Based on the 27583 marriage records, the index of endogamy, the intensity of metisation and ethnic marriage assortativness in 8 regions of North Ossetia and Vladikavkaz have been analyzed. The differences in the marriage and migration characteristics are revealed for two subethnoses: the Irons and the Digors. The Digors have a higher value of endogamy index and a lower metisation level than the Irons have.

Кленовники Северного Кавказа – особый тип лесных формаций. Особенность проявляется не только в структуре фитоценозов, но и в способах самовозобновления. Объект исследования – чистые и смешанные кленовники в нескольких урочищах РСО-Алания. Объекты расположены в различных условиях горного рельефа и на разной высоте над уровнем моря, от 1100 до 1900 м. Целью исследования является установление особенностей семенного возобновления кленовников, произрастающих в верхнем поясе распространения лесов на Северном Кавказе. Для достижения поставленной цели устанавливали время цветения и созревания семян по вертикальным поясам распространения кленовников. Обилие цветения и средний балл плодоношения устанавливали по В.Г. Капперу. Биометрические характеристики семян определяли по урочищам в трех повторностях. Учет подроста проводили на круговых учетных площадках по 10 м2, в соответствии с методикой А.В. Грязькина. Установлено, что цветение клена Траутфеттера начинается 10–14 мая и заканчивается в третьей декаде мая. Семена начинают созревать к концу августа – к началу сентября. Сроки опадения семян растянуты. Часть семян попадает на почву до начала листопада, поэтому они оказываются погребенными под опадом. Такие семена быстро теряют всхожесть, выпревают. Другая часть опадает вместе с листьями. Третья категория семян (самые легкие) держатся на деревьях до декабря и даже до весны. Естественное возобновление клена семенами под пологом материнского древостоя сильно затруднено из-за мощного травяного покрова. В древостое с сомкнутым пологом доля цветущих и плодоносящих деревьев составляет 2–3%, а средний балл плодоношения составляет 1,3. Освещенность на поверхности почвы не превышает 100 люкс, т. е. составляет 0,2–0,3% от освещенности на открытом месте; на высоте 1,3 м (над травостоем) освещенность несколько выше – от 1,2 до 1,6 тыс. люкс. Под пологом древостоя преобладает подрост вегетативного происхождения. У верхней границы кленового леса подрост семенного происхождения встречается в окнах, прогалинах и на открытых местах в количестве 430–630 экз./га. По высоте преобладает крупный подрост 50–60%, доля мелкого – 10–20%. The maple stands of the North Caucasus – a special type of forest formations. The peculiarity is manifested not only in the structure of phytocoenoses, but also in the ways of self-renewing. Object of research – pure and mixed maple stands in some areas of North Ossetia-Alania. The properties are located in various mountainous terrain and at different heights above sea level from 1100 to 1900 m. The aim of the study is to establish the characteristics of the seed the resumption of the maple stands growing in the upper belt of forests spread in the Northern Caucasus. To achieve this goal setting time of flowering and ripening of seeds on vertical zones distribution dominated. The abundance of flowering and the average score of fruiting was established by V.G. Capper. Biometric characteristics of the seeds was determined by the tracts in three replicates. Accounting for the undergrowth was carried out on a circular experimental plots at 10 m2, in accordance with the method of A.V. Grashkin. It is established that the flowering maple Trautvetter begins may 10–14 and ends in the third week of may. Seeds begin to ripen by late August – early September. The timing of subsidence of the stretched seed. Some of the seeds falls to the ground before the leaves, so they are trapped under the litter. These seeds quickly lose their germination, vypivaet. The other part falls along with the leaves. The third category of seeds (the light) stay on the trees until December and even till spring. Natural regeneration of maple seeds under the canopy of parent stand is very difficult due to the strong grass cover. In forest stands with dense canopy, proportion of flowering and fruit-bearing trees is 2–3%, and the average score of fruiting is 1.3. The illumination on the surface of the soil does not exceed 100 Lux, i. e. 0.2–0.3% of the light in the open, at a height of 1.3 m (on grass) the lighting is slightly higher, from 1.2 to 1.6 thousand Suite. Under the canopy of the forest the undergrowth is dominated by vegetative origin. At the upper boundary of the maple forest, saplings of seed origin occurs in Windows, clearings and open places in the number 430–630 ind./ha. In height dominated by large undergrowth of 50–60%, the share of small – 10–20%.

SummaryIntra-population socioeconomic changes and migration are powerful factors in changing eating habits. Changes in eating habits could affect the nutritional status, growth, development and health of adolescents. The aim of this study was to compare the diet of adolescents of Moroccan origin living in Spain with that of adolescents living in Morocco. The sample comprised 428 Moroccan adolescents aged from 12 to 19 recruited in high schools: 327 living in Ouarzazate (Morocco) and 101 living in Madrid (Spain). The variables studied were energy intake (kcal/day), diet quality indicators (adherence to the Mediterranean Adequacy Index (MAI); cholesterol intake (mg/day); fibre intake (g/day) and energy profile)); and indicators of keeping traditional customs (halalmeat consumption, bread made at home). Teenagers from Morocco living in Madrid consumed more calories, proteins, saturated fats and simple sugars (p<0.001) than those living in Morocco. Their diet was of lower quality than that of their peers in Morocco. This difference was more marked in boys than in girls. Changes in eating habits associated with migration from the south to the north Mediterranean basin can benefit young migrants in an immediate way (through greater availability of energy and nutrients), but later in life it could have negative consequences for their health, increasing the risk of overweight, obesity and cardiovascular and metabolic problems.

The general population genetic characteristics of cultivated horse chestnut trees excelling in growth, phenotype characteristics, type of inflorescence, productivity and resistance to the leafminer Cameraria ohridella Deschka and Dimic were analyzed in Serbia. The analyzed population genetic parameters point to fundamental differences in the genetic structure among the cultivated populations in Serbia. The study shows the variability in all properties among the populations and inter-individual variability within the populations. The variability and differential characteristics were assessed using statistical parameters, taking into account the satisfactory reflection of the hereditary potential. The assessed differences in the vitality and evolution potential of different populations can determine the methods of horse chestnut gene pool collection, reconstruction and improvement.

Abstract Goat breeding is a traditional livestock industry for many regions of Russia. Due to unpretentiousness and high adaptive qualities, the Karachai, Dagestan wool and Dagestan down breeds are widespread in the North Caucasus. Moreover, their uniqueness is determined by sharing a common habitat with their wild relatives, West Caucasian and Dagestani turs, thus forming hybrid zones. The aim of the research was to study allele pool and interbreed differentiation of domestic goat breeds and wild relatives by microsatellites. Research was performed based on 16 loci on the ABI 3130xl analyzer. Population genetic characteristics were calculated in GenAlEx 6.5, and the phylogenetic tree was constructed in Populations 1.2.30 and SplitsTree 4.14.5. The sample collection included goat breeds (n = 226): Karachai (KRCH), Dagestan down (DAGD), Dagestan wool (DAGW) (North Caucasus), Soviet wool (SOVW) (Siberia), Orenburg (OREN) (South Ural), and wild goats (n = 72). Wild goats comprised mountain goats: Siberian goats (Capra sibirica) from the Altai, Tajikistan, Kyrgyzstan and the Himalayas; bezoar goats (Capra aegagrus) from Turkey and Pakistan; and tur (Capra caucasica) from the West Caucasus (Kuban), Central Caucasus, and East Caucasus (Dagestan). The Karachai breed was characterized by the highest level of genetic diversity: the average number of alleles per locus (NA) and allelic richness (AR) were 9,154 and 7,713, respectively, while these indices varied from 6,538 to 7,538 and from 6,425 to 7,538 (Table 1) in other breeds, respectively. The values of genetic distances showed differentiation of Karachai, Dagestan down and Dagestan wool breeds from Orenburg and Soviet wool breeds (Table 2). The formation of three clusters was established. The first one included subspecies of the Caucasian tur, the second one comprised Siberian goats, and the third contained domestic goats. Bezoar goats were in the root of the third cluster that confirmed their participation as an ancestral form of domestic goats.

The North Pyrenean Zone corresponds to the palaeopassive margin of the North Iberia plate, at the foot of which subcontinental mantle was exhumed during Albian times. Rare bodies of exhumed mantle rocks associated with strongly sheared lenses of continental crust are scattered among the North Pyrenean Zone metasediments. Significant fluid flow occurred along a major décollement at the basement–Trias interface in the Urdach massif (Chaînons Béarnais). Fluids with a broad range of salinity (10–38 wt.% NaCl equiv.), indicative of mixing between brines and more dilute waters, produced strong silicification of breccias. The brines circulated at c. 240–280°C under lithostatic pressures at c. 6 ± 1 km depth. The fluids became increasingly saline towards the final stages. The syndeposition of Cenomano-Turonian flysch layers then progressively isolated the lower aquifers close to the décollement where Triassic brines were predominant. The release and migration of significant volumes of brines during stretching and squeezing of the Triassic evaporites played a crucial part in the mineralogical and rheological transformations that occurred during the Pyrenean Cretaceous rifting event.
