“…In the subtropical forests of southern Brazil, temperature has been observed to influence the dominant ecological strategy of communities, being mainly C under warm conditions and S under cooler conditions [38]. In contrast, two other studies conducted at local scales have shown that tree communities in a resource-limited coastal ecosystem rather converge towards S/CS strategies [23,37].…”

“…Ecological strategies, i.e., combinations and trade-offs between different trait values, reflect the processes by which species acquire, invest in, and use resources to survive and increase their fitness and survival [22]. Species may thus have different combinations of functional traits to pursue the same ecological strategy [23]. The ecological strategy approach also has the potential to be easier to link to invasion hypotheses than approaches focused on separate traits.…”

Understanding the mechanisms of biological invasions (e.g., competitive exclusion) is a key conservation challenge, especially on islands. Many mechanisms have been tested by comparing the characteristics of native and alien species, but few studies have considered ecological strategies. Here we aim at comparing the competitive ability, stress tolerance, and ruderalism (CSR) of native and alien trees in the tropical rainforests of Réunion Island. A total of sixteen 100 m2 plots (eight ‘near-trail’ and eight ‘off-trail’, at less disturbed sites) were established over a 2100 m elevational gradient. Three traits were measured in 1093 leaves from 237 trees: leaf area, leaf dry matter content and specific leaf area. They were converted into a CSR score assigned to each of the 80 surveyed tree species (70 native and 10 alien) using the ‘Stratefy’ ordination approach. C scores increased with basal area and S scores with elevation, but R scores were not higher along the trail, thus only partially validating Stratefy. Native and alien trees had similar CS strategies, thus challenging invasion hypotheses predicting a difference in ecological strategies and rather demonstrating the importance of environmental filtering. However, other differences falling outside the CSR theory may also explain the success of alien species on Réunion.

“…Plant functional traits determine adaptability in the strategic trade-offs for plants to environments [9,12]. Hence, ecological strategy tradeoffs are associated with plant functional traits in regulation through long-term evolution adaptivity [45][46][47]. Therefore, we hypothesized that CSR strategy depends on trade-offs in regulations associated with plant functional traits in karst forests (H2).…”

The Grime (1974) CSR framework posits that ecological strategies of competition, stress tolerance and ruderal reflect plants’ adaptability to their survival environments. Karst forests are crucial for terrestrial ecosystem functions. However, how karst forests regulate plant functional traits in ecological strategy to adapt to infertile habitats remains unclear. Therefore, we surveyed fifty-three karst forest plots and measured plant functional traits involving the plan diameter at breast height (DBH), height, leaf area (LA), specific leaf area (SLA), leaf dry matter content (LDMC), leaf carbon (LC) and nitrogen (LN) and phosphorus (LP) with the leaf water content (LWC). We calculated CSR components on the individual and community levels introduced by community-weighted means (CWM) using the ‘StrateFy’ calculator. Principal component analysis (PCA) and Mantel’s test were used to investigate trait correlations with CSR components. Our results showed that stress tolerance (S) contributed an average 65.88% and 63.63% in individuals and communities, respectively, followed by competition (C) at 25.82% and 29.63%, and the least, ruderal (R), at 8.30% and 6.74%. Different plant functional traits exhibited different variations, coupled with significant correlations between CSR components and PC1 scores (except for CWM− LA, SLA and LDMC). Component S increased with the increase in CWM− LC and C:N ratio, and decreased with the increase in CWM− DBH, Height, LWC, LN, and N:P ratio, while it was the opposite for C and R, highlighting strategic trade-offs associated with plant functional traits. Mantel’s test revealed varied key trait combinations for each strategy. In conclusion, the predominant stress tolerance strategy relative to competition and ruderal is a result of trade-offs regulating karst forests, in association with plant functional traits. The disentangled CSR strategies provide insights into theoretically understanding functional maintenance for infertile forest ecosystems as an evolutional regulation mechanism.

“…Variation of leaf functional traits has been found to indicate a trade-off between a resource-acquisition strategy and a resource-conservation strategy [21]. For example, plants adopting acquisitive strategies tend to present higher specific leaf area (SLA) and leaf nitrogen content (LNC) and lower leaf dry matter content (LDMC), since they invest in traits capable of assuring greater resource acquisition [22]. The trade-off and correlation between these leaf functional characteristics show the adaptation of plants to the environment [23].…”

Leaf functional traits are the essential components of adaption plant strategies and have different responses to various environments, but our knowledge of how plants adapt to highly complex urban environments through coordinated changes in leaf functional traits is limited. In this study, we studied the response of landscape plants to the environments of sports field (SF), park (PAR), residential green space (RES), and greenway (GW), and analyzed the effects of the different green space environments on trade-off strategies of plants based on leaf functional traits. The results showed that leaf functional traits of plants and adaptation strategies varied among different urban environments in Lanzhou, China. Leaf length (LL), width (LW), area (LA), and special leaf area (SLA) were PAR > SF > RES > GW. Leaf nitrogen (LNC) and phosphorus content (LPC) were SF > PAR > RES > GW. Leaf carbon content (LCC), leaf dry matter content (LDMC), the ratio of leaf carbon and nitrogen (C/N), and the ratio of leaf carbon and phosphorus (C/P) was GW > RES > PAR > SF. The landscape plants in SF and PAR were more adaptive to the urban environment than those in RES and GW. Among different green space environments, landscape plants in SF and PAR tended to have an acquisitive strategy with high LL, LW, LA, SLA, LNC, and LPC. In contrast, plants in RES and GW tended to have a conservative strategy with a high level of concentration of LCC, LDMC, C/N, and C/P.
