Data from: Abundance-dependent effects of neighborhood dissimilarity and growth rank reversal in a Neotropical forest

Yuxin Chen, María Natalia Umaña, María Uriarte & Shixiao Yu
Why tropical forests harbor an exceptional number of species with striking differences in abundances remains an open question. We propose a theoretical framework to address this question in which rare species may have different extirpation risks depending on species ranks in tree growth and sensitivities to neighborhood interactions. To evaluate the framework, we studied tree growth and its responses to neighborhood dissimilarity (ND) in traits and phylogeny for 146 species in a Neotropical forest. We...

Data from: Study on the optimization of the deposition rate of planetary GaN-MOCVD films based on CFD simulation and the corresponding surface model

Jian Li, Ze-Yuan Fei, Yi-Feng Xu, Jie Wang, Bing-Feng Fan, Xue-Jin Ma & Gang Wang
Metal-organic chemical vapour deposition (MOCVD) is a key technique for fabricating GaN thin film structures for light-emitting and semiconductor laser diodes. Film uniformity is an important index to measure equipment performance and chip processes. This paper introduces a method to improve the quality of thin films by optimizing the rotation speed of different substrates of a model consisting of a planetary with seven 6-inch wafers for the planetary GaN-MOCVD. A numerical solution to the transient...

Data from: Seeing is believing? comparing plant-herbivore networks constructed by field co-occurrence and DNA barcoding methods for gaining insights into network structures

Chunchao Zhu, Dominique Gravel & Fangliang He
Plant-herbivore interaction networks provide information about community organization. Two methods are currently used to document pairwise interactions among plants and insect herbivores. One is the traditional method that collects plant-herbivore interaction data by field observation of insect occurrence on host plants. The other is the increasing application of newly developed molecular techniques based on DNA barcodes to the analysis of gut contents. The second method is more appealing because it documents realized interactions. To construct...

Data from: Mechanisms of reciprocity and diversity in social networks: a modelling and comparative approach

Ivan Puga-Gonzalez, Julia Ostner, Oliver Schülke, Sebastian Sosa, Bernard Thierry & Cedric Sueur
Three mechanisms have been proposed to underlie reciprocation of social behaviors in gregarious animals: ‘calculated reciprocity’, ‘emotional bookkeeping’ and ‘symmetry-based reciprocity’. Among these explanations, emotional book-keeping has received the broadest support from experimental and observational studies. On the other hand, three individual-based models have shown that reciprocation may emerge via ‘symmetry-based reciprocity’, ‘emotional bookkeeping’, or a combination of both mechanisms. Here we use these three models to assess their relative fit with empirical data on...

Data from: Correlation of native and exotic species richness: a global meta-analysis finds no invasion paradox across scales

Shijia Peng, Nicole L. Kinlock, Jessica Gurevitch, Shao-Lin Peng & Shaolin Peng
Support for the “biotic resistance hypothesis,” that species-rich communities are more successful at resisting invasion by exotic species than are species-poor communities, has long been debated. It has been argued that native-exotic richness relationships (NERR) are negative at small spatial scales and positive at large scales, but evidence for the role of spatial scale on NERR has been contradictory. However, no formal quantitative synthesis has previously examined whether NERR is scale-dependent across multiple studies, and...

Data from: Soil microbes promote complementarity effects among co-existing trees through soil nitrogen partitioning

Shan Luo, Bernhard Schmid, Gerlinde B. De Deyn & Shixiao Yu
1. Plant resource partitioning is a mechanism promoting species coexistence and ecosystem functioning. Yet, we still have limited understanding of how soil microbes, especially plant symbiotic microbes, influence resource partitioning. We hypothesized that soil borne microbes, in particular mycorrhizal fungi, facilitate differential performance of tree species depending on different nitrogen sources and that this leads to a positive plant diversity–community productivity relationship. 2. We conducted two complementing glasshouse experiments. In a “monoculture experiment”, we supplied...

Data from: Are vocal characteristics related to leadership patterns in mixed-species bird flocks?

Emilio Pagani-Núñez, Xue Xia, Guy Beauchamp, Ruchuan He, John H.D. Husson, Dan Liang, Eben Goodale & John H. D. Husson
What structures the organization of mixed-species bird flocks, so that some ‘nuclear’ species lead the flocks, and others follow? Previous research has shown that species actively listen to each other, and that leaders are gregarious; such gregarious species tend to make contact calls and hence may be vocally conspicuous. Here we investigated whether vocal characteristics are associated with leadership, using a global dataset of mixed-species flock studies and recordings from sound archives. We first asked...

Data from: The early history of Annonaceae (Magnoliales) in Southeast Asia suggests floristic exchange between India and Pan-Indochina by the late Oligocene

Qijia Li, Gongle Shi, Yusheng Liu, Qiongyao Fu, Jianhua Jin & Cheng Quan
The collision between India and Eurasia in the mid‐Palaeogene facilitated terrestrial floristic exchange. However, due to the complexity of this geological event and scarcity of fossil record, the plant migration patterns between the two plates are still highly debated. In this study, we focus on the Oligocene floristic exchange between India and Pan‐Indochina mainly based on a carpological study of Annonaceae, an emblematic family unique in its pantropical distribution and frugivore‐based dispersal strategy. A new...

Data from: Re-association of an invasive plant with its specialist herbivore provides a test of the Shifting Defence Hypothesis

Jinlong Wan, Bei Huang, Hua Yu & Shao-Lin Peng
1. The shifting defence hypothesis (SDH) predicts that after invasive plants are introduced to new ranges, they will evolve reduced resistance to specialist herbivores and increased resistance to generalist herbivores because they can escape from specialists but are still attacked by generalists in their non-native ranges. For this to be true, the subsequent introduction of native specialist herbivores should reverse the above evolutionary processes, but evidence collected so far is scarce. 2. Here, we address...

Data from: Habitat effects on intra-species variation in functional morphology: evidence from freshwater fish

Fangmin Shuai, Shixiao Yu, Sovan Lek & Xinhui Li
Biotic-environment interactions have long been considered an important factor in functional phenotype differentiation in organisms. The differentiation processes determining functional phenotypes can reveal important mechanisms yielding differences in specific functions of animal traits in the ecosystem. In the present study we examined functional morphological variations in relation to increasing geographic altitude. Six fish species were examined for how environment factors affect intra-specific functional morphology in the subtropical Pearl River in southern China. Functional morphology traits...

Data from: Strain specific differences in rates of Photosystem II repair in picocyanobacteria correlate to differences in FtsH protein levels and isoform expression patterns

Erin M. Bonisteel, Brooke E. Turner, Cole D. Murphy, Jenna-Rose Melanson, Nicole M. Duff, Brian D. Beardsall, Kui Xu, Douglas A. Campbell & Amanda M. Cockshutt
Picocyanobacteria are the numerically dominant photoautotrophs of the oligotrophic regions of Earth’s oceans. These organisms are characterized by their small size and highly reduced genomes. Strains partition to different light intensity and nutrient level niches, with differing photosynthetic apparatus stoichiometry, light harvesting machinery and susceptibility to photoinactivation. In this study, we grew three strains of picocyanobacteria: the low light, high nutrient strain Prochlorococcus marinus MIT 9313; the high light, low nutrient Prochlorococcus marinus MED 4;...
