“…Some fundamental relationships found in leaf economics spectrum research include a significantly positive correlation between LT and Suc, which confirms that succulent plants employ a water conservation strategy [46]. While a significantly negative correlation has been found between LT and C content, this can be related to thicker LT causing a decrease in the specific leaf area which affects carbon acquisition [50].…”

“…The results of this study indicate that L. ruthenicum has a flexible strategy under different desert saline habitats: when soil salinity is high, foliar N is small, and the C:N ratio is large, a defensive strategy is adopted; when N contents are high and the C:N ratio is low, a competitive survival strategy is adopted. Leaf thickness (LT) is generally considered to be a very important leaf trait characteristic, which may be related to leaf life span, stress tolerance, and litter decomposition rate [46][47]. Osmond et al [48] The existence of a fundamental trade-off between the rapid acquisition and the efficient conservation of resources has been discussed in the ecological literature for more than forty years.…”

Background: Soil salinization affects plant growth and causes changes in leaf traits. Lycium ruthenicum Murr., a shrub with significant soil and water conservation capacities. In this paper, we analyze the trade-offs of leaf functional traits of eight L.ruthenicum populations growing at varying distances from the Heihe river by dividing the eight sites into three groups according to the average soil salinity and discussing the effects of soil factors at 0-40cm and 40-80cm on leaf trait patterns. We also attempt to explain desert L.ruthenicum trade-off strategies by choosing fourteen leaf traits to link with soil factors. Results: Low N contents indicated that L.ruthenicum was located at the slow investment-return axis of the species resource utilization graph. Compared to non-saline and very slightly saline sites, populations of slightly saline sites showed higher C:N. The redundancy analysis "RDA" results showed that 0-40cm and 40-80cm soil properties explained 70.99% and 71.09% of leaf trait variation, respectively. As soil salinity gradients increased, leaf C:N increased and N content decreased, and the difference was significant. Populations in non-saline and very slightly saline habitats tended to have higher leaf C content, while populations in slightly saline habitats tended to have lower leaf C content, and the discrepancy was evident. Relative importance analysis found that in the 0-40cm layer, leaf traits variations were mainly influenced by soil water content (SWC), HCO3-and CO32-, while leaf trait variations in the 40-80cm layer were mainly influenced by HCO3- and SO42-ions. Conclusions: The growth of L. ruthenicum in the Ejina desert is mainly restricted by N content, which determines soil fertility. L.ruthenicum has a foliar resource acquisition method and a resource conservation trade-off with a flexible life history strategy. Leaf traits can vary significantly due to different environments in a given habitat. As the environmental gradient changes from mild to severe, the populations present a pattern of increased C:N,increased C content, reduced N:P, and reduced N content. In the shallow soil layers of saline-stressed arid environments,water has a greater effect than salt on leaf trait variation.In both shallow and deep soil layers, HCO3- ions have a relatively large effect on leaf properties.

“…El recambio entre BPE y BMM fue intermedio, de 20 especies registradas en cada uno de estos dos bosques, 12 de ellas fueron compartidas, pero los valores de su diversidad en rasgos funcionales fueron muy diferentes. Los resultados aquí no permiten detectar un patrón entre la diversidad de orquídeas y su variación funcional presente en los tres tipos de vegetación, pero hacen posible notar que la diversidad de especies puede ser mayor a la diversidad de rasgos funcionales si la comunidad presenta especies redundantes (hay similitud en la variación de sus rasgos funcionales), como indicó el valor de la diversidad promedio funcional más cercana en BPE (Chacón-Labella et al 2016, Coux et al 2016, Gould et al 2016, Morandeira & Kandus 2016.…”

Antecedentes:Los rasgos funcionales de las plantas se relacionan con sus estrategias adaptativas y son importantes en la diversidad de sus ecosistemas, pero han sido poco estudiados. Por sus adaptaciones en los ambientes estacionales, las orquídeas terrestres son un modelo para estudiar las relaciones entre diversidad taxonómica y funcional con el ambiente. Preguntas: ¿Cómo cambia la diversidad de orquídeas y sus rasgos funcionales entre tipos de vegetación? ¿Los rasgos funcionales permiten reconocer grupos de orquídeas? ¿La diversidad y rasgos funcionales de orquídeas se asocian con variables ambientales? Sitio y años de estudio: La Reserva de la Biosfera El Cielo, enero 2016 a enero 2017. Métodos: Se registró riqueza, abundancia y rasgos funcionales de orquídeas terrestres, así como variables ambientales en tres tipos de vegetación, estimando diversidad verdadera y funcional y recambio de especies. Se analizó la variación en rasgos funcionales para identificar grupos funcionales; se evaluaron las relaciones entre diversidad, rasgos funcionales y variables ambientales. Resultados: El bosque mesófilo de montaña y de pino-encino presentaron mayor diversidad verdadera, recambio de especies y diversidad funcional que el bosque tropical subcaducifolio. Se reconocieron tres grupos funcionales determinados por rasgos asociados a la acumulación y conservación de reservas. La diversidad taxonómica y funcional se relacionó con temperatura, humedad y densidad del dosel. No hubo relación entre riqueza y abundancia con diversidad funcional. Conclusiones: La diversidad taxonómica no determina la diversidad funcional; ambientes sometidos a mayor estrés ambiental presenta mayor diversidad funcional. La composición de grupos funcionales evidencia eventos de convergencia en rasgos funcionales.

“…Such large-scale events also drive changes in terms of habitat suitability, leading to conditions that restrict some life forms, such as increasing depth for emergent species (Akasaka et al, 2010 ). In this sense, environmental disturbances at large spatial scales cause the substitution of macrophyte species and macrophyte life forms, which in turn change the macrophyte taxonomic and composition of life forms across the landscape (e.g., Neiff, 1979 ; Bini, 1996 ; Junk and Piedade, 1997 ; Morandeira and Kandus, 2016 ).…”

“…Because macrophytes are important components of aquatic ecosystems in terms of biomass production and habitat structuring and present particularities regarding the responses of life forms to environmental factors, understanding the relationships between life forms and environmental and morphometric factors might provide the stepping stone to improving the knowledge of ecosystem processes. However, most of the investigations in aquatic ecosystems using a functional approach have focused on the drivers of richness and composition of macrophyte life forms (Akasaka et al, 2010 ; Akasaka and Takamura, 2011 ; Netten et al, 2011 ; Alahuhta and Heino, 2013 ; Alahuhta et al, 2013a ; Alahuhta, 2015 ; Morandeira and Kandus, 2016 ; Toyama and Akasaka, 2017 , among others), but research on the relationship between the biomass (or primary productivity) of particular life forms and the changes in environmental factors is still scarce (Sand-Jensen and Sondergaard, 1979 ; Lampert and Sommer, 1997 ; Hudon et al, 2000 ; Stromberg and Merritt, 2015 ). Because the mechanisms by which diversity is expected to affect ecosystem functioning depend on the functional characteristics of local communities, assessing the relative importance of the abiotic variables to the biomass of particular life forms and to the life forms composition of the assemblages is key for comprehending the structure and dynamics of ecosystems.…”

Macrophyte assemblages are composed of species with different life forms and various ecological functions. Our aim was to investigate the potential environmental determinants of changes in the biomass of individual life forms and of the composition of the macrophyte assemblage in terms of life forms diversity. We sampled 23 waterbodies at low and high water levels in the Middle Paraná River floodplain. Macrophyte biomass samples were collected and classified in terms of life forms. We performed a redundancy analysis using the biomass of the various life forms to assess the importance of environmental variables to the composition of macrophyte life forms. Linear regressions were applied to investigate the environmental determinants of the biomasses of individual life forms. The degree of connectivity and the combination of depth, hydrology and nitrate were the main determinants of the composition in terms of life forms. The biomass of each individual life form was explained by different combinations of environmental variables, but the connectivity was the most important one. Our study shows that groups of species with similar life forms respond to environmental factors in particular ways, which might alter the biomass composition of life forms. Given that the ecosystem functioning depends on the functional characteristics of local communities, our findings about the relation between environmental changes and the community composition in terms of life forms (or functional composition) can be a helpful tool for predicting changes on ecosystem processes (such as nutrient cycling) against possible future scenarios.
