Data from: Community functional trait composition at the continental scale: the effects of non-ecological processes
Ecological communities and their response to environmental gradients are increasingly being described by measures of trait composition at the community level – the trait-based approach. Whether ecological or non-ecological processes influence trait composition between communities has been debated. Understanding the processes that influence trait composition is important for reconstructing paleoenvironmental conditions from fossil deposits and for understanding changes in community functionality through time. Here, we assess the influence of ecological and non-ecological processes on the distribution of traits within North American mammals. We found that non-ecological processes including historical contingency, spatial autocorrelation, and evolutionary history do not influence trait composition; however, the variance in trait composition is highly explained by climate gradients. Our results suggest that habitat breadth, terrestriality, diet breadth, and reproductive traits are strong candidates as proxies for measuring functional aspects of environments in the past and present.
Data from: A global perspective on the functional responses of stream communities to flow intermittence
<p>The current erosion of biodiversity is a major concern that threatens the ecological integrity of ecosystems and the ecosystem services they provide. Due to global change, an increasing proportion of river networks are drying and changes from perennial to non-perennial flow regimes represent dramatic ecological shifts with potentially irreversible alterations of community and ecosystem dynamics. However, there is minimal understanding of how biological communities respond functionally to drying. Here, we highlight the taxonomic and functional responses of aquatic macroinvertebrate communities to flow intermittence across river networks from three continents, to test predictions from underlying trait-based conceptual theory. We found a significant breakpoint in the relationship between taxonomic and functional richness, indicating higher functional redundancy at sites with flow intermittence higher than 28%. Multiple strands of evidence, including patterns of alpha and beta diversity and functional group membership, indicated that functional redundancy did not compensate for biodiversity loss associated with increasing intermittence, contrary to received wisdom. A specific set of functional trait modalities, including small body size, short life span and high fecundity, were selected with increasing flow intermittence. These results demonstrate the functional responses of river communities to drying and suggest that ongoing biodiversity reduction due to global change in drying river networks is threatening their functional integrity. These results indicate that such patterns might be common in these ecosystems, even where drying is considered a predictable disturbance. This highlights the need for the conservation of natural drying regimes of intermittent rivers to secure their ecological integrity.</p>
Intraspecific trait variation and species turnover mediate grazing impacts on above- and below-ground functional trait composition of plant communities
<ol> <li>Although grazing has significant impacts on plant functional traits and community composition in grasslands, few studies have simultaneously explored how plant above- and below-ground traits and community functional composition respond to grazing.</li> <li>Using a grazing manipulation experiment with seven levels of grazing intensity (0, 1.5, 3.0, 4.5, 6.0, 7.5, and 9 sheep ha<sup>-1</sup>) in the Inner Mongolia grassland, we partitioned the roles of intraspecific trait variation (ITV) and species turnover underlying the grazing induced changes in above- and below-ground functional trait composition of plant communities. Six aboveground traits (i.e. plant height, plant aboveground biomass, plant density, leaf area, specific leaf area (SLA) and leaf density) and three root traits (average root diameter, ARD; specific root length, SRL; and root tissue density, RTD) of the first-, second- and third-order roots (1<sup>st</sup>-, 2<sup>nd</sup>-, and 3<sup>rd</sup>-) were measured at the plant individual level. </li> <li>At the community level, plant above-ground traits shifted towards grazing avoidance strategy (e.g. plant height and leaf area decreased), and below-ground traits shifted towards conservative strategy (i.e. 1<sup>st</sup>-SRL and 2<sup>nd</sup>-SRL decreased, 1<sup>st</sup>-RTD and 2<sup>nd</sup>-ARD increased) with increasing grazing intensity. Functional tradeoffs were found between plant individual biomass and plant density, and between leaf area and leaf density under grazing. However, community-weighted mean SRL (SRL<sub>CWM</sub>) and ARD (ARD<sub>CWM</sub>) of different root orders exhibited functional coordination under grazing pressure. SLA<sub>CWM</sub> and SRL<sub>CWM</sub> also showed synergistic responses to grazing.</li> <li> The ITV plays a predominant for the changes in above- and below-ground functional trait composition at the community level. However, changes in mean trait values among plant species with different resource use strategies were mainly triggered by species turnover. For species with different resource use strategies, grazing exhibited a coordinated effects on ITV but an offset effect on species turnover.</li> <li> <i>Synthesis.</i> Our results demonstrate that both the above- and below-ground trait composition of plant communities shifted toward conservative strategy under long-term grazing. This study highlights the effects of ITV and species turnover that govern the grazing-induced changes in functional trait composition of plant communities, and has important implications for grazing management in semiarid grasslands.</li> </ol>

Data from: Functional attractors in microbial community assembly
<p>For microbiome biology to become a more predictive science, we must identify which descriptive features of microbial communities are reproducible and predictable, which are not, and why. We address this question by experimentally studying parallelism and convergence in microbial community assembly in replicate glucose-limited habitats. Here, we show that the previously observed family-level convergence in these habitats reflects a reproducible metabolic organization, where the ratio of the dominant metabolic groups can be explained from a simple resource-partitioning model. In turn, taxonomic divergence among replicate communities arises from multistability in population dynamics. Multistability can also lead to alternative functional states in closed ecosystems, but not in metacommunities. Our findings empirically illustrate how the evolutionary conservation of quantitative metabolic traits, multistability, and the inherent stochasticity of population dynamics, may all conspire to generate the patterns of reproducibility and variability at different levels of organization that are commonplace in microbial community assembly.</p>
