Abstract

Aims

The overall balance of multiple chemical elements in plant tissue has likely great adaptive significance for species in natural environments. By using alpine plants as a study system, we examined the relationship between a species' position within the Competitiveness–Stress–Tolerance–Ruderal (CSR) strategy scheme and the chemical elemental composition in its leaves.

Location

Alpine meadows in the Caucasus (Karachai-Cherkess Republic, Russia) and Tatra mountains (Slovakia).

Methods

We collected leaf material from 50 species in the Caucasus and 23 species in the High Tatras, with some species sampled in both regions. Macro and micronutrient as well as heavy metal contents were measured in leaf biomass. For each species, we calculated a CSR strategy based on its measured leaf traits.

Results

A wide spectrum of CSR strategies was found across the studied species. Competitiveness (C strategy) dominated in Veratrum album, Polygonum bistorta, and Gentiana punctata from the Tatras. The most significant differences in element concentrations were observed between stress-tolerant (S) and ruderal (R) strategies. K, S, Mg, Ca, Cl, Rb, Zn, Cu, Sr, and Na (for Tatra and Caucasian) and N and P (for Caucasian) plants showed a significant negative relationship with proportional adherence to the S strategy, with only Si exhibiting a positive correlation with the S strategy. Meanwhile, Ca, Cl, Cu, Fe, K, Mg, Mo, N, Na, P, S, and Zn showed positive proportional adherence to the R strategy. The C strategy was positively correlated with K, Mg, and Rb for all species as well as with N and P for Caucasian plants, but negatively correlated with Fe, Cr, Mo, and Si.

Conclusions

Overall, CSR strategies had a close relation with macro- and micro-nutrient concentrations in leaves of alpine plants. Plants from different regions (Caucasus and Tatras) showed similar trends.

高山植物CSR策略与叶片元素化学的关系

目的植物组织中多种化学元素的整体平衡可能对物种在自然环境中具有重要的适应意义。本文以高山植物为研究对象，研究了植物叶片化学元素组成与竞争-抗逆性-抗逆性（CSR）策略的关系。地理位置：高加索（俄罗斯卡拉恰伊-切尔克斯共和国）和塔特拉山脉（斯洛伐克）的高山草甸。方法在高加索地区采集50种植物的叶片资料，在高海拔地区采集23种植物的叶片资料。测定了叶片生物量中常量、微量元素及重金属含量。对于每个物种，我们根据其测量的叶片特征计算了CSR策略。结果在研究物种中发现了广泛的CSR策略。竞争策略（C策略）在龙舌兰、历史蓼和龙胆中占主导地位。在抗逆性(S)和一般性(R)策略之间，元素浓度的差异最为显著。K、S、Mg、Ca、Cl、Rb、Zn、Cu、Sr和Na（适用于白土和高加索）以及N和P（适用于高加索）与S策略的比例依从性呈显著负相关，只有Si与S策略呈正相关。同时，Ca、Cl、Cu、Fe、K、Mg、Mo、N、Na、P、S和Zn对R策略的依从性呈正正比关系。C策略与K、Mg、Rb和N、P呈显著正相关，与Fe、Cr、Mo、Si呈显著负相关。结论总体而言，CSR策略与高山植物叶片中宏、微量养分浓度密切相关。来自不同地区（高加索和塔特拉）的植物表现出类似的趋势。

期刊介绍： The Journal of Vegetation Science publishes papers on all aspects of plant community ecology, with particular emphasis on papers that develop new concepts or methods, test theory, identify general patterns, or that are otherwise likely to interest a broad international readership. Papers may focus on any aspect of vegetation science, e.g. community structure (including community assembly and plant functional types), biodiversity (including species richness and composition), spatial patterns (including plant geography and landscape ecology), temporal changes (including demography, community dynamics and palaeoecology) and processes (including ecophysiology), provided the focus is on increasing our understanding of plant communities. The Journal publishes papers on the ecology of a single species only if it plays a key role in structuring plant communities. Papers that apply ecological concepts, theories and methods to the vegetation management, conservation and restoration, and papers on vegetation survey should be directed to our associate journal, Applied Vegetation Science journal.
