“…Additionally, Singh et al [ 58 ] reported that LA in tree species is directly related to PM concentrations, because at higher LA, tree species retain more PM [ 70 ]. Some researchers [ 16 , 17 ] suggested that the previous trend was a response to urban pressures and that this varied with the tree species considered. Thus, the findings suggest that the identification of these variations in leaf traits may have a significant influence during the selection of tree species for the urban air pollution monitoring [ 1 , 58 , 65 ].…”

“…Functional traits are defined as the set of phenological, morphological, and physiological characteristics that plants possess to ensure their survival success, provide insight into ecological dynamics, and responses to changes in the environment [ 15 ]. Leaf area (LA), specific leaf area (SLA), and leaf dry matter content (LDMC) are among the most evident leaf functional traits (macro-morphological), due to their easy measurement and sensitivity to environmental variations, [ 16 , 17 ]. There are other leaf functional traits (micro-morphological), such as stomatal density, leaf thickness, leaf type, and minimal photosynthetic unit, that have a great influence on ecosystem processes such as primary productivity, biogeochemical cycles, and organic matter decomposition [ 6 , 18 ].…”

Urban trees provide different ecosystem benefits, such as improving air quality due to the retention of atmospheric particulate matter (PM) on their leaves. The main objective of this paper was to study, through a systematic literature review, the leaf macro-morphological traits (LMTs) most used for the selection of urban trees as air pollution biomonitors. A citation frequency index was used in scientific databases, where the importance associated with each variable was organized by quartiles (Q). The results suggest that the most biomonitored air pollutants by the LMTs of urban trees were PM between 1–100 µm (Q1 = 0.760), followed by O3 (Q2 = 0.586), PM2.5 (Q2 = 0.504), and PM10 (Q3 = 0.423). PM was probably the most effective air pollutant for studying and evaluating urban air quality in the context of tree LMTs. PM2.5 was the fraction most used in these studies. The LMTs most used for PM monitoring were leaf area (Q1) and specific leaf area (Q4). These LMTs were frequently used for their easy measurement and quantification. In urban areas, it was suggested that leaf area was directly related to the amount of PM retained on tree leaves. The PM retained on tree leaves was also used to study other f associated urban air pollutants associated (e.g., heavy metals and hydrocarbons).

“…Functional traits represent morphological, physiological, structural, and phenological adaptations that species have developed to survive climatic variations in their inhabited ecosystems (Rodríguez-Alarcón et al 2020 ). These traits can show intraspecific and interspecific variations essential for the structure and dynamics of natural communities (Salgado-Negret 2016 ; Faccion et al 2021 ).…”

Functional traits can have intraspecific and interspecific variations essential in the structure and dynamics of natural communities. These traits may have implications in the germination and seedling establishment phases in seeds. The objective of this study was to evaluate the effect of variations in mass, volume, and nutrient content (C, N, and P) on the germination of eight species representative of the tropical dry forest (TDF). Our results showed that seed size, both in terms of mass and volume, did not predict germination rates or percentages, nor were they related to nutrient content. In contrast, N content was the most important trait in the germination phase. Larger seeds did not germinate more or faster, but they could offer better resistance against desiccation, since they had higher C/N ratios in their tissues, a characteristic of orthodox seeds. The species A. guachapele, B. arborea, H. crepitans, and V. tortuosa presented a high biological potential in terms of their regeneration capacity, particularly, because the characteristics of their seeds, as well as the nutrient content, revealed consistent implications in their reproductive success, promoting high germination percentages in less time. In general, the results obtained in this study provide basic knowledge for future research, offering starting points for further exploration of species-specific adaptations and how they may be affected by the environment.
