“…On the contrary, the phenologically later species, e.g., some Castilleja or Gentiana species, are not able to produce seeds if the season in a temperate alpine region is too short. In Montana in 2019, neither Castilleja nor Gentiana were able to produce seeds because of the short season, while both species successfully reproduced in the longer 2018 season (Křenová et al, 2019). In the subtropical alpine region, delayed flowering can cause fruit ripening in times of low soil moisture, when plants are withering before delivering the ripe seeds.…”

“…Populations of three target species were studied in Line Creek Plateau Research Natural Area, located near the Montana/Wyoming border, United States (Appendix 1). Line Creek Plateau is the easternmost alpine area in the Beartooth Mountains, where alpine plant phenology has been already studied (Křenová et al, 2019). Part of the study site occurs in the community types with Geum rossii (Castilleja pulchella), while the other part (with Caltha leptosepala and Gentiana algida) occurs in the Salix glauca/Deschampsia cespitosa c.t.…”

Alpine plants are perceived as some of the most vulnerable to extinction due to the global climate change. We expected that their life history strategies depend, among others, on the latitude they live in: those growing in temperate regions are likely to have a distinct phenology with short seasonal peaks, while tropical alpine plants can potentially exploit favorable year-round growing conditions and different individuals within a population may flower at different times of the year. In species, whose flowering is synchronized into short seasonal peaks, extraordinary climate events, which may become stronger and more frequent with climate change, can potentially destroy reproductive organs of all synchronized individuals. This may result in reducing fitness or even extinction of such species. We studied field populations of five groups of closely related Andean alpine plant species to test our expectations on their latitude-dependent synchronization of flowering. Our results confirmed these expectations: (i) Tropical alpine species were least synchronized and flowering peaks of different individuals in their populations were distributed across many months. Thus, in tropical alpine species, if an extraordinary event happens, only some individuals are affected and other members of the population successfully reproduce in other parts of the long season. (ii) Higher synchronicity in flowering of temperate and subtropical alpine plants resulted even in some of these species using only a part of the short growing season to reproduce, which increases their vulnerability to extraordinary climatic events. However, we did not find any unique pattern valid for all species, groups and regions. The diversity in flowering phenology (i.e., different levels of seasonality and synchronicity) that we found increases the likelihood of plants successfully coping with climate change.

“…Все более активно развивается направление, связанное с созданием каменистых садов в условиях города. Основой ассортимента для каменистых композиций являются растения гор и горных осыпей, но культивирование некоторых из них вызывает трудности в регионах с иными климатическими условиями [Křenová, 2019;Kudo, 2019]. При этом, несмотря на достаточно локальное распространение ряда горных видов, среди них было выявлено достаточное количество таксонов, которые оказались пластичными при выращивании в нетипичных для них условиях [Буданцев, 2020;Tokhtar et al, 2021].…”

В настоящее время использование декоративных каменистых композиций в системе городского озеленения снова становится одним из актуальных направлений. Большое значение имеет жесткий отбор растений, проявляющих наибольшую устойчивость в климатических условиях региона и экологических условиях городов. В статье изложен опыт создания рокариев на территории Главного ботанического сада им. Н.В. Цицина РАН (ГБС РАН). Работа, в основном, выполнена на базе анализа сводного перечня скальных декоративных травянистых многолетников из состава коллекционного фонда лаборатории декоративных растений, включающего 108 наименований. Изучены изменения таксономического состава видов, использованных в ходе многолетних экспериментов. Выявлено, что наиболее стабильны и перспективны для широкого применения в каменистых композициях представители семейств Campanulaceae, Caryophyllaceae, Geraniaceae, Plumbaginaceae, Polemoniaceae, Cistaceae и Crassulaceae. При сопоставлении географических условий установлено, что в анализируемом эксперименте преобладали виды-представители флор Северной Америки, Кавказа, Восточной Азии, Евразии и Европы (в первую очередь Южной). Поэтому их правомерно считать наиболее перспективными регионами-донорами для привлечения декоративных травянистых растений, в дальнейшем используемых в рокариях. Проанализирована закономерность распределения изучаемых растений по их экологической приуроченности. Выявлено, что доминируют горные виды (35,2% от общего числа использованных в полевом опыте), лесные виды составляют 28,3%, 12,7% видов характеризуются приуроченностью к луговым сообществам. Currently, the use of decorative stony compositions in the urban landscaping system is again becoming one of the relevant directions. Strict selection of plants showing the greatest stability in the climatic conditions of the region and the ecological conditions of cities is of great importance. The article presents the experience of creating rockeries on the territory of the N.V. Tsitsin Main Botanical Garden of the Russian Academy of Sciences (MBG RAS). The work was mainly carried out on the basis of the analysis of the consolidated list of rock ornamental herbaceous perennials from the collection fund of the department (currently - laboratory) of ornamental plants, including 108 names. Changes in the taxonomic composition of the species used in the course of long-term experiments have been studied. It was revealed that the most stable and promising for widespread use in stony compositions are representatives of the families Campanulaceae, Caryophyllaceae, Geraniaceae, Plumbaginaceae, Polemoniaceae, Cistaceae and Crassulaceae. When comparing geographical conditions, it was found that the analyzed experiment was dominated by species-representatives of the flora of North America, the Caucasus, East Asia, Eurasia and Europe (primarily species from Southern Europe). Therefore, it is legitimate to consider them the most promising donor regions for attracting ornamental herbaceous plants, which are later used in rockeries. The regularity of the distribution of the studied plants according to their ecological relevance is analyzed. It has been revealed that mountain species dominate (35.2% of the total number used in the field experiment), forest species account for 28.3%, 12.7% of species are characterized by their association with meadow communities.
