Data from: Species pools and differential performance generate variation in leaf nutrients between native and exotic species in succession

Kirstin I. Duffin, Shaopeng Li, Scott J. Meiners & Shao-Peng Li
1. A central aim of invasion biology has been to identify key functional differences between native and exotic species to determine which traits may be responsible for invasion success and impacts. There are two primary ways that differences may exist between native and exotic species - the traits of the local species pools may differ, or the way that the traits interact with their environment may differ. 2. We explored leaf nutrient concentrations as functional...

Data from: Plant functional diversity modulates global environmental change effects on grassland productivity

Zhuwen Xu, Mai-He Li, Niklaus E. Zimmermann, Shaopeng Li, Hui Li, Haiyan Ren, Hao Sun, Xingguo Han, Yong Jiang, Lin Jiang & Shao-Peng Li
1. Although much research has explored changes in ecosystem functions associated with global environmental changes, the mechanistic pathways behind the observed changes remain poorly understood. 2. Using an 11-year experiment that increased growing season precipitation and nitrogen deposition in a temperate steppe, we explored the relative importance of direct and indirect environmental change effects on plant primary productivity. 3. We show that increases in water and nitrogen availability influenced plant productivity via both direct and...

Data from: Nitrogen addition does not reduce the role of spatial asynchrony in stabilizing grassland communities

Yunhai Zhang, Jinchao Feng, Michel Loreau, Nianpeng He, Xingguo Han & Lin Jiang
While nitrogen (N) amendment is known to affect the stability of ecological communities, whether this effect is scale‐dependent remains an open question. By conducting a field experiment in a temperate grassland, we found that both plant richness and temporal stability of community biomass increased with spatial scale, but N enrichment reduced richness and stability at the two scales considered. Reduced local‐scale stability under N enrichment arose from N‐induced reduction in population stability, which was partly...

Data from: Hawkmoth flight in the unsteady wakes of flowers

Megan Matthews & Simon Sponberg
Flying animals maneuver and hover through environments where wind gusts and flower wakes produce unsteady flow. Although both flight maneuvers and aerodynamic mechanisms have been studied independently, little is known about how these interact in an environment where flow is already unsteady. Moths forage from flowers by hovering in the flower’s wake.We investigated hawkmoths tracking a 3D-printed robotic flower in a wind tunnel.We visualized the flow in the wake and around the wings and compared...

Data from: Niche and fitness differences determine invasion success and impact in laboratory bacterial communities

Shao-Peng Li, Jiaqi Tan, Xian Yang, Chao Ma & Lin Jiang
There is increasing awareness of invasion in microbial communities worldwide, but the mechanisms behind microbial invasions remain poorly understood. Specifically, we know little about how the evolutionary and ecological differences between invaders and natives regulate invasion success and impact. Darwin’s naturalization hypothesis suggests that the phylogenetic distance between invaders and natives could be a useful predictor of invasion, and modern coexistence theory proposes that invader-native niche and fitness differences combine to determine invasion outcome. However,...

Data from: Genetics of a de novo origin of undifferentiated multicellularity

Matthew D. Herron, William C. Ratcliff, Jacob Boswell & Frank Rosenzweig
The evolution of multicellularity was a major transition in evolution and set the stage for unprecedented increases in complexity, especially in land plants and animals. Here we explore the genetics underlying a de novo origin of multicellularity in a microbial evolution experiment carried out on the green alga Chlamydomonas reinhardtii. We show that large-scale changes in gene expression underlie the transition to a multicellular life cycle. Among these, changes to genes involved in cell cycle...
