Abstract
The paper discusses the growth dynamics ofDicranum polysetumSw. in artificial pine communities of theKrasnosamarskyForest (Samara Region) and the National Park Buzuluksky Bor (Samara and Orenburg Regions). These species are most commonly found in these types of communities.The authors note the vitality ofDicranum polysetumSw. and its relation to the size of the moss curtain. The studies were conducted in the summers of 2015, 2016 and 2017. The moss was studied at 12 sitesof theartificial pine forests of the Krasnosamarsky forest and the National ParkBuzuluksky Bor. Three individuals were selected at each site, the growth and vitality of them were noted during the study period. It was revealed that the smallest growth was on the sites of the smallest moss curtain in both study areas. It was also found that the microrelief and grassy layer can significantly affect moss growth. It was noted that the vitality score was higher in large clumps in the absence of any mechanical damage to the curtain, and that the shoots form twigs, on average, every two years, thereby increasing their biomass, because the area of curtains did not significantly change during the study period.

Phase portrait; seasonal index; air temperature; amplitude; Surgut; territory of Far North; weather sensitivity; circulatory system diseases
The paper is devoted to the analysis of weather and climate variability on the example of the northern territory of Surgut and its influence on the population health indicators
The author has evaluated the cases of emergency hospitalization of Surgut population with circulatory system diseases in the dynamics of 2010–2014 and calculated the seasonal index for these diseases for men and women, indicating the activation of seasonal factors for almost every month
Summary
Таблица 3 – Линейные размеры изучаемых побегов верхоплодного мха Dicraum polysetum Sw. за период 2015–2017 гг. в национальном парке «Бузулукский бор», мм. В Красносамарском лесном массиве прирост составил 2,27 мм с жизненностью 2,3 балла, в Бузулукском бору – 3,7 мм с жизненностью 3,0 балла; в 2016–2017 гг. На 3-й и 4-й площадках за этот же период в Красносамарском лесном массиве прирост составил 3,4 и 2,2 мм (площадь куртинок: 24 и 36 см, жизненность по 3,0 балла) и 4,6 и 4,4 мм (площадь куртинок: 18 и 23 см, жизненность по 3,0 балла) в Бузулукском бору. За 2016–2017 года на этих же площадках линейный рост мха увеличился на 5,8 и 5,2 мм в Красносамарском лесном массиве (при жизненности 2,0 и 2,7 баллов соответственно) и 7,0 и 12,8 мм в Бузулукском бору (при жизненности 3,0 и 2,7 баллов соответственно). Наибольший линейный рост мха за 2015–2016 год был отмечен площадке No 5: в Красносамарском лесном массиве он составил 5,8 мм при площади около.
