“…C, N, P, and AP contents were determined according to the potassium dichromate, Kjeldahl, molybdenum anti-colorimetric, and molybdenum blue methods. K and AK contents were determined using the flame photometry method and NO 3 − -N and NH 4 + -N contents using the ultraviolet spectrophotometry method [ 77 , 78 , 79 ].…”

“…For growth traits, specific leaf area (SLA) was the leaf area (measured using an LI-3000C leaf area meter; Li-COR, Lincoln, NE, USA) divided by the dry weight. Concentrations of leaf carbon (LCC) and nitrogen (LNC) were determined using the potassium dichromate method and the modified Kjeldahl method, respectively [ 77 ]. Concentrations of leaf phosphorus (LPC) and nitrates (Nitrate) were determined using the molybdenum anti-colorimetric method, on the one hand and the ultraviolet spectrophotometry, on the other [ 46 , 77 ].…”

Although the effects of N deposition on forest plants have been widely reported, few studies have focused on rare and endangered fern species (REFs). Information is also lacking on the effects of micro-environments on REFs. We investigated the effects of N addition (canopy and understory N addition, CAN, and UAN) and micro-environments (soil and canopy conditions) on the functional traits (growth, defense, and reproduction; 19 traits in total) of two REFs—Alsophila podophylla and Cibotium baromet—in a subtropical forest in South China. We found that, compared to controls, CAN or UAN decreased the growth traits (e.g., plant height, H) of C. baromet, increased its defense traits (e.g., leaf organic acid concentrations, OA), delayed its reproductive event (all-spore release date), and prolonged its reproductive duration. In contrast, A. podophylla showed increased growth traits (e.g., H), decreased defense traits (e.g., OA), and advanced reproductive events (e.g., the all-spore emergence date) under CAN or UAN. Meanwhile, the negative effects on the C. baromet growth traits and A. podophylla defense traits were stronger for CAN than for UAN. In addition, the soil chemical properties always explained more of the variations in the growth and reproductive traits of the two REFs than the N addition. Our study indicates that, under simulated N deposition, C. baromet increases its investment in defense, whereas A. podophylla increases its investment in growth and reproduction; this may cause an increasing A. podophylla population and decreasing C. baromet population in subtropical forests. Our study also highlights the importance of considering micro-environments and the N-addition approach when predicting N deposition impact on subtropical forest REFs.

“…In recent years, affected by global climate change and an intensification of human activities, many plants have been in a state of endangered extinction, leading to a loss of biodiversity [ 1 ]. The conservation and utilization of plant resources is currently one of the most important development strategies in China and even around the world [ 2 ]. Woody plants are of immense economic, cultural, and ecological importance, and efforts are urgently required to prevent the loss of woody species and the associated ecosystem services that they support [ 3 ].…”

Ex situ conservation plays an important role in the conservation and utilization of plant resources. In recent years, botanical gardens have greatly improved the ex situ conservation of plants, and research has mainly focused on morphological characteristics, reproduction technology, and conservation value. There are few studies on the ecophysiological traits of plants after conservation. Forty-seven plants that are frequently used in North China and were grown in the Beijing Botanic Garden were selected to measure their photosynthetic traits, light-use efficiency (LUE), water–use efficiency (WUE), specific leaf area (SLA), relative chlorophyll content (SPAD), and leaf water potential (φ). An analysis of variance showed that there were significant differences in the ecophysiological traits of the leaves of 47 woody species. The light saturation point (LSP), net photosynthetic rate at light saturation (Pnmax), φ, and SLA had significant differences among different plant life forms. The SLA and SPAD of leaves were significantly different among the families. The LUE of all species reached its maximum under a low light intensity, and species with a large difference between the light saturation point and light compensation point had larger Pnmax values. This research further adds to the understanding of the adaptation mechanisms of plants to the environment under the conditions of a botanical garden as well as the environmental fitness in a long-term ex situ domestication and then helps with scientifically setting up artificial management conditions.

“…Succession leads to divergence in vegetative traits (Lohbeck et al, 2014; Marcilio‐Silva et al, 2016), and vegetative and reproductive responses to successional gradients might be linked due to resource utilization strategies expressed in both traits (Han et al, 2019). We may thus expect more distinct reproductive traits associated with distinctive functions to occur in old‐growth forests, as reported for larger‐seeded plants interacting with larger‐bodied frugivorous birds (Emer et al, 2019).…”

Questions: Do old-growth forests retain more evolutionary history and more reproductive trait diversity along the successional gradient? How similar are the phylogenetic branches and reproductive attributes at each phase? In which succession stages are distinct lineages of trees and shrubs present? Do distinct lineages have distinct traits? Is there a turnover of species, lineages and traits of trees and shrubs along the successional gradient?Location: Atlantic Forest, Reserva Natural Guaricica (25°19′ S, 45°42′ W) and Reserva Natural das Águas (25°21′ S, 48°46′ W), Antonina, Paraná, southern Brazil. Methods:We assessed the variation of alpha and beta taxonomic, functional and phylogenetic diversities of tree and shrub communities along a successional gradient (phase 1, stand initiation phase, from 0 to 9 years old; phase 2, stem exclusion phase, 10-25 years old; and phase 3, understorey re-initiation phase, 25-200 years old). We also evaluated the occurrence of distinct lineages and traits related to seed dispersal and pollination.Results: In addition to the expected change in species composition, lineages and trait states and values were replaced along the chronosequence, with stronger variation for trees. Old-growth forests harbor distinct lineages and traits and a greater amount of evolutionary history and functional diversity of reproductive traits. We also found that distinct lineages were those that performed distinct functions. Conclusions:Our study showed that as the succession proceeds, turnover of lineages and traits occurred, with the understorey re-initiation stage harboring the largest taxonomic, phylogenetic and functional diversity. In addition, understories of the re-initiation stage are important for the occurrence of distinct lineages, such as magnoliids, and of distinct traits, such as large fruits and seeds, which highlights the importance of conservation of old-growth forests, and its preservation can prevent the loss of distinct evolutionary histories and functions.
