“…In other words, the meadow and willow–shrub tundra had distinct species compositions, but both communities were dominated by species with traits of a conservative strategy. Similar trends have been observed in the successions of agricultural land in the highlands of South America (Rada et al., 2021), suggesting that changes in functional traits during secondary succession after agricultural use are common in harsh climatic conditions.…”

“…Numerous studies have been conducted on the recovery of tundra vegetation after fires (Racine et al., 2004; Bret‐Harte et al., 2013; Heim et al., 2021; Hollingsworth et al., 2021), grazing (Kryazhimskii et al., 2011; Mörsdorf et al., 2021), trampling (Monz, 2002), and industrial impact (Sumina, 1994; Kevan et al., 1995; Forbes et al., 2001; Jorgenson et al., 2010; Kearns et al., 2015). However, we found only a few publications that focus on the restoration of tundra (alpine) vegetation after agricultural use (Kotelina et al., 1998; Archegova et al., 2002; Panyukov et al., 2005; Rada et al., 2021). Analysis of the secondary succession of tundra phytocoenoses after agricultural use can help evaluate how vegetation responds to substrate disturbance, nitrification, or periodic biomass removal from plant communities under adverse climatic conditions, limited mineral nutrients, and low overall productivity (Truett & Kertell, 1992; Soudzilovskaia et al., 2005).…”

AimsTundra communities are known for their harsh environmental conditions and tundra is one of the most vulnerable biomes on Earth. Restoring these unique communities after anthropogenic impact is crucial for the sustainable development of northern regions. The objective of this study was to evaluate the recovery of subarctic tundra after long‐term agricultural use.LocationSubarctic zone, European northeast, Vorkuta district, Komi Republic, Russia.MethodsIn the latter half of the twentieth century, large areas of tundra were plowed and cultivated with cereals to be used as fodder in livestock farms. These areas were subsequently abandoned (1990–2000) and the stage of natural recovery began. From 1960 to 2017 one of these plant communities was regularly assessed and we used these data, along with data from a reference tundra community, to examine changes in community assembly. We evaluated biodiversity indices, functional diversity using various plant traits and phylogenetic diversity.ResultsAgricultural management in tundra areas has led to the development of a meadow community that differs significantly from the typical tundra found in similar landscapes. The highest level of meadow biodiversity was observed under moderate anthropogenic pressure. The most significant changes in plant community assembly were observed after withdrawal from agricultural use. The average plant height, leaf area, and leaf dry matter content increased, while the average specific leaf area and leaf nitrogen content decreased. The functional and phylogenetic clustering was replaced by overdispersion.ConclusionsOver the 20‐year period following the cessation of agricultural use, we observed a decrease in the vitality of cultivated cereals and overall biodiversity. However, there was a redistribution of species abundance rather than a complete change in species composition. Deciduous and evergreen shrubs have not become introduced in sufficient abundance to transform the artificial meadow into the typical subarctic willow–shrub tundra. This is a fundamental difference between abandoned agricultural lands of the tundra zone and those of more southern regions, which are rapidly overgrown with pioneer tree or shrub species.

“…This resulted in high LNC, LPC, and LKC [14]. Significant positive correlations have been reported between the maximum photosynthesis rate and SLA [67,68], LNC [68][69][70], LPC and LKC [70,71]. Species with high SLA, LNC, LPC, and LKC typically occur in nutrient rich and light-limiting habitats.…”

Disturbances have created heterogeneous habitats for secondary and old-growth forests. Under the assumption that ecologically similar species have similar functional traits, numerous studies have attempted to use trait-based approaches to infer the abiotic and biotic factors that drive variations in community composition across different forests. However, the relative importance of these drivers in monsoon forests remains poorly understood. In this study, we randomly selected 86 plots and classified them into three forest types according to environmental factors: 1—secondary forests: secondary forest habitats at high elevation; 2—ecotone forests: general recovery and elevation; and 3—old growth forests: old growth at low elevations. We then compared the species and six leaf functional trait variations across the three forests and assessed their relationships with 15 environmental factors. The results showed that secondary and ecotone forests with a conservative strategy, exhibiting high dry matter content and leaf carbon content, tended to persist in stressful habitats, such as nutrient-poor soil, whereas old growth forests invested in trait values related to rapid resource acquisition with high specific leaf area, leaf nitrogen content, leaf phosphorous content, and leaf potassium content. Species with functional trait values between the secondary, ecotone, and old growth forests had clear signatures of their different strategies to persist in assemblages under distinct and opposite environmental filters. These plots were classified into three forest types according to environmental factors: (1) secondary forest at high elevation; (2) ecotone forests at general elevation; and (3) old growth forests at low elevation. Recovery time and elevation, followed by soil nutrients and light capture, were the most important factors shaping species and functional trait variations across forests. These results have demonstrated that environmental filters select plant species with distinct traits and ecological strategies. Acquisitive traits indicate higher competitive ability and faster resource acquisition for forest species that occur in areas with high soil fertility. Meanwhile, conservative traits promote the resistance of secondary species to environmental stressors in low soil fertility, suggesting that analyzing leaf functional-based trait variations to understand plant ecological strategies along an environmental gradient may improve understanding of forest dynamics in tropical monsoon forests.
