“…There may be compounds within a mixture that by themselves intoxicate or repel a plant antagonist, although it is more likely that several compounds act against the attacker in an additive or synergistic manner (Espinosa-García & Langenheim 1991b;García-Rodríguez et al 2021, Macel et al 2005. The relative importance of the activity of single compounds and mixtures varies with the host range of plant attackers.…”

Biodiversity in ecosystems is crucial in providing ecosystem services and their stability and resilience. However, most studies supporting the benefits of biodiversity in crop health were studied at the cultivar scale, generally without specifying the resistance mechanisms involved in the resistance of crops to pests. Thus, it is unclear if phytochemical diversity is one of those resistance mechanisms and whether the ecosystem patterns and processes in which phytochemical diversity is involved can be replicated or adapted to the management of sustainable agroecosystems. Here, I review the roles of phytochemical diversity in natural ecosystems and determine if they can be helpful in the management of agroecosystems. I briefly review (a) the spatial and temporal structure of phytochemical diversity in ecosystems and its effect on plant consumers; (b) how that diversity is generated and maintained; and (c) the current or potential role of phytochemical diversity in agroecosystems. The α-, β-, and γ-phytochemical diversities are very high in ecosystems and landscapes; phytochemical diversity gets displayed in dynamic mosaics of mixtures of secondary metabolites that vary in their concentration and composition within and among individuals, populations, or species. Phytochemical diversity is fostered by evolutionary or coevolutionary processes, mainly under an arms-race scenario. The patterns and processes of phytochemical diversity are idiosyncratic depending on the identity of the interacting species and the local biotic and abiotic environment; thus, to copy them to industrial agroecosystems is hardly viable. However, five recommendations in which phytochemical diversity could be helpful in agroecosystem management are made.

“…Plants synthesize a large number of compounds, including secondary metabolites, many are volatile compounds that vary in composition and concentration between species and from one individual to another within the same species (García-Rodríguez, Bravo-Monzón, Martínez-Díaz, Torres-Gurrola, & Espinosa-García, 2012). Such variation also depends on the plant part being analyzed, the season of the year, geographical origin and other environmental factors (Kopaczyk et al, 2020).…”

“…Such variation also depends on the plant part being analyzed, the season of the year, geographical origin and other environmental factors (Kopaczyk et al, 2020). Secondary metabolites are synthesized in small quantities and not in a generalized way (some are produced only by one species, genus or family) (Pichersky & Raguso, 2018); they play defense, attraction or competition functions, and their effectiveness depends on the concentration (López-Goldar et al, 2018) and metabolism of the consumer: herbivore or pathogenic (García-Rodríguez et al, 2012).…”

“…Dicha variación también depende de la parte la planta que se analice, la estación del año, origen geográfico y otros factores medioambientales (Kopaczyk et al, 2020). Los metabolitos secundarios se sintetizan en cantidades pequeñas y no de forma generalizada (algunos son producidos solo por una especie, género o familia) (Pichersky & Raguso, 2018); cumplen funciones de defensa, atracción o competencia, y su efectividad depende de la concentración (López-Goldar et al, 2018) y del metabolismo del consumidor: herbívoro o patógeno (García-Rodríguez et al, 2012).…”

Introduction: A species’ populations differ across its distribution due to selection pressure from the climate gradient. Objective: To describe the phytochemical variation among 14 tree provenances in an altitudinal gradient of Abies religiosa (Kunth) Schltdl. & Cham. to determine if there are associations of chemical profiles among populations, expressed under a single environment. Materials and methods: Seeds were collected from 165 trees from an altitudinal transect from 2 850 to 3 540 m in Cerro San Andrés, Municipio Libre de Hidalgo, Michoacán, Mexico. The plant was grown in a common garden trial; at 28 months, mature needles were collected per tree and analyzed by gas-mass chromatography. Data were analyzed with diversity indices, ANOVA and multivariate analysis (principal components, correspondences and cluster). Results and discussion: Thirty-two compounds were identified, most of them terpenes. The populations showed differences in presence/absence of terpenes and in their concentration; above 3 350 m, diversity was lower, but with higher concentration. Three altitude groups were found based on the chemical profile of the populations: low = 2 850 to 3 300 m and 3 400 m; moderate = 3 350, 3 450 and 3 500 m; and high= 3 540 m. Conclusions: The diversity and concentration of terpenes in A. religiosa varied depending on the altitude of populations. There are three chemical profiles that should be considered in the implementation of germplasm collection programs for reforestation and restoration
