Orchids (Orchidaceae Juss.) in the Southern Urals: Ecological-Phytocoenotic and Population Characteristics, Anthropotolerance, Antecology

Abstract: Приводятся итоги изучения видов сем. Orchidaceae Juss. флоры Южного Урала в пределах Республики Башкортостан на охраняемых и иных территориях. Комплексные исследования ведутся по одной схеме с применением единых подходов и методов. Изучены распространение, численность, популяционная структура (размерный и возрастные спектры и др.), экология, репродуктивная биология 29 видов разных жизненных форм (всего 286 ценопопуляций). Итогом исследований является выявление стратегий жизни видов и разработка на этой основе … Show more

“…By the nature of their behavior in plant communities, most orchids are phytocoenotic and ecotopic patients, stenovalent and stenobiont species that require specific ecological and phytocoenotic conditions [20,21]. The distribution of nutrients between the processes of reproduction and vegetative growth with biomass accumulation prevails in rhizomatous species, which can be attributed to k-strategists.…”

“…In particular, this is due to the fact that Cypripedium is a phytocoenotic and ecotopic patient (stress tolerant) (Zaugolnova et al 1992) intolerant to competition of other herbs when growing in swamps, screes, and overgrown quarries. In coniferous, mixed coniferous-broad-leaved, broad-leaved, small-leaved, and mixed coniferous-smallleaved forests, as well as in transitional mires, Cypripedium po pu lations are dominated by adult vegetative and generative plants (Tatarenko 1996, Ishmuratova et al 2003, Bychenko 2010, Barabantsova & Berdnikova 2017, Fardeeva et al 2020. Tatarenko (1996) gives a basic spectrum of 0 % : 8 % : 44 % : 48 % (j : im : v : g) for populations of C. calceolus and C. macranthos.…”

“…However, Fardeeva et al (2022) identified three types of basic age spectra for C. calceolus: 1) centered (3 : 11 : 47 : 40), the most common in the European part of the Russia; 2) bimodal (15 : 26 : 33 : 26), predominantly found in western regions; 3) right-sided (0 : 3 : 13 : 82 : 2) (j : im : v : g : s) which manifests in the continental climate of the eastern regions of European Russia. In C. calceolus, the predominance of juvenile (up to 58 %) and/or immature (up to 52 %) plants was observed only in populations on river valley slopes with sparse moss and grass cover (Puchnina 1999), in peatmoss pine forests (Ishmuratova et al 2003, Fardeeva et al 2022, or in swampy habitats and lime stone outcrops (Teteryuk 2003). This indicates a fairly active seed renewal along with the vegetative reproduction, provided there is no competition from other plants and the luminosity is optimal.…”

“…Небольшой разброс и низкие показатели антропотолерантных видов свидетельствуют о невысокой устойчивости L. ovata к антропогенному воздействию и уязвимости вида, что отмечали и исследователи из других регионов [9][10][11].…”

“…В Кировской области встречается редко [8]. Об уязвимости вида к антропогенному воздействию указывают И. В. Суюндуков [9], М. М. Ишмуратова с соавторами [10], М. Ш. Барлыбаева с соавторами [11]. По данным М. Г. Вахрамеевой, Т. И. Варлыгиной [12] и М. Г. Вахрамеевой с соавторами [13], L. ovata обладает устойчивостью к сенокошению, слабому выпасу, слабой рекреации и беглым пожарам.…”
