Abstract Functional traits offer promising avenues to investigate how community composition and diversity define ecosystem functioning service delivery. In recent years, many empirical studies on the importance of functional for provisioning have been undertaken, but a general understanding synthesis results is lacking ecosystems. Here we focus temperate grasslands present systematic literature review synthesizing plant are interrelated with services. Based 108 studies, identified core set 40 11 Several these were only linked one, while 75% two or more We found that trait‐specific constraints can lead both synergies trade‐offs in supply multiple For instance, between biomass production climate regulation be achieved by changing morphometric root such as increasing diameter, tissue density shoot ratio. On other hand, supporting fast‐growing exploitative species characterized high specific leaf area nitrogen content typically leads fodder quality water purification. Synthesis applications . By applying network analysis, five groups services sharing common traits. Within among groups, well options synergies. These particularly useful landscape planning, when management aims maintaining multifunctionality ecosystems maximizing corresponding

The role of fine‐root mass, specific root length and life span in tree performance: A whole‐tree exploration

Abstract The root economics spectrum (RES) hypothesis predicts that fast‐growing tree species have short‐lived roots with high specific length (SRL) to allow rapid resource uptake, and opposite trait expressions for slow‐growing species. Yet, the mixed support this suggests trees can adopt alternative strategies increase besides an in SRL. We combined a novel mechanistic whole‐tree model empirical fine‐root data of 10 test effects one these strategies, notably increasing mass, on tree's net C gain (used here as proxy performance), assess how life span influences relative importance SRL mass balance trees. Our results indicate accounting short high‐SRL has important implications explaining performance role herein. Without considering their faster turnover, low resulted highest predicted from RES. when higher turnover rates were accounted for, lead performance.

Different phylogenetic and environmental controls of first‐order root morphological and nutrient traits: Evidence of multidimensional root traits

Functional Ecology, Год журнала: 2017, Номер 32(1), С. 29 - 39

Abstract Although fine roots are essential for the water and nutrient uptake of plants, there is limited understanding root trait variation underlying mechanism. Here, six first‐order morphological chemical traits were measured 181 species from eight subtropical boreal forests to test hypothesis different phylogenetic environmental regulations result in multidimensions traits. Two independent dimensions between thickness detected at both community levels. At level, diameter‐related mainly restricted by structure showed little plasticity changing environments, whereas woody was influenced significantly soil variables. For community‐level traits, axis scores principal component analysis driven mean annual temperature through shifting composition, nutrient‐related strongly P availability. From levels, our study confirms, that root‐thickness‐related dimension represent new support multidimensionality which selection pressure. This also underlines community‐aggregated might serve as a promising avenue improve assemblage processes, allowing us predict changes vegetation distributions climate.

Few facets of biology vary more than functional traits and life-history traits. To explore this vast variation, ecologists population have developed independent approaches that identify the mechanisms behind consequences trait variation.Collaborative research between researchers using trait-based demographic remains scarce. We argue is a missed opportunity, as strengths both could help boost agendas ecology ecology.This special feature, which spans three journals British Ecological Society due to its interdisciplinary nature, showcases state-of-the-art applying examine relationships organismal function, life history strategies performance across multiple kingdoms. Examples include exploration how × environment interactions affect vital rates thus explain trends species occurrence; coordination seed dispersal ability with pace in plants; incorporation dynamic energy budget models; or discovery linkages microbial fast-slow continuum.Despite their historical isolation, collaborative work unlock novel pathways. call for an integrative agenda evaluate when are functional, well describe predict dynamics. highlight promising, complementary avenues overcome current limitations.

Root traits are more than analogues of leaf traits: the case for diaspore mass

New Phytologist, Год журнала: 2017, Номер 216(4), С. 1130 - 1139

Опубликована: Сен. 12, 2017

Root traits are often thought to be analogues of leaf along the plant economics spectrum. But evolutionary pressures have most likely shaped above- and belowground patterns differentially. Here, we aimed identify important aboveground for explaining root without an a priori focus on known concepts. We measured morphological in glasshouse experiment 141 common Central European grassland species. Using random forest algorithms, built predictive models six from 97 morphological, ecological life history traits. tissue density was best predicted by dry matter content, whereas related fineness were diaspore mass: heavier diaspore, coarser system. Specific area (SLA) not predictor any This study confirms hypothesis that more than within The results reveal novel pattern highlight power data close knowledge gaps trait-based ecology.
