Data from: Bacteria, protists and fungi may hold clues of seamount impact on diversity and connectivity of planktonic community

Rongjie Zhao
The interacting features of topography and hydrography around deep seamounts have strong influence on plankton biogeography. In addition, the intrinsic properties of various biological taxa inherently shape their distribution. Therefore, bacterial, protist and fungal diversity was investigated across the water column above and below the summit of a flat-topped seamount in the Western Pacific Ocean. We determined the distribution and connectivity patterns of bacteria, protists and fungi around the seamount, and explored the processes driving...

Effectively and accurately mapping global biodiversity patterns for different regions and taxa

Alice Hughes, Michael C. Orr, Qinmin Yang & Huijie Qiao
Aim To understand the representativeness and accuracy of expert range maps, and explore alternate methods for accurately mapping species distributions. Location Global Time period Contemporary Major taxa studied Terrestrial vertebrates, and Odonata Methods We analyzed the biases in 50,768 animal IUCN, GARD and BirdLife species maps, assessed the links between these maps and existing political and various non-ecological boundaries to assess their accuracy for certain types of analysis. We cross-referenced each species map with data...

Changes in species composition mediate direct effects of climate change on future fire regimes of boreal forests in northeastern China

Chao Huang, Hong He, Yu Liang, Todd Hawbaker, Paul Henne, Wenru Xu, Peng Gong & Zhi Zhu
1. Direct effects of climate change (i.e., temperature rise, changes in seasonal precipitation, wind patterns, and atmospheric stability) affect fire regimes of boreal forests by altering fire behavior, fire seasons, and fuel moisture. Climate change also alters species composition and fuel characteristics, which subsequently alter fire regimes. However, indirect effects of climate change are often simplified or neglected in the direct climate-fire relationship models and dynamic global vegetation models. This may result in high uncertainties...

Species packing and the latitudinal gradient in local beta-diversity

Ke Cao, Richard Condit, Xiangcheng Mi, Lei Chen, Wubing Xu, David F. R. P. Burslem, Chunrong Cai, Min Cao, Li-Wan Chang, Chengjin Chu, Hu Du, Sisira Ediriweera, C. S. V. Gunatilleke, I. U. A. N. Gunatilleke, Zhanqing Hao, Jinbo Li, Guangze Jin, Buhang Li, Yankun Liu, Yide Li, Michael J. O'Brien, Xiujuan Qiao, Hongwei Ni, Guochun Shen, Xihua Wang … & Jens-Christian Svenning
The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall local species richness (gamma diversity) remains hotly debated. Previous studies that failed to resolve the issue suffered from a well-known tendency for small samples in areas with high gamma-diversity to have inflated measures of beta-diversity. We provide here a novel analytical test, using beta-diversity metrics...

Information and sequences of the six lineages identified in the H1N1 influenza A virus

Chaoyuan Cheng & Zhibin Zhang
The influenza virus mutates and spreads rapidly, making it an ideal model for studying evolutionary and ecological processes. The ecological factors and processes by which different lineages compete or coexist within hosts, through time and across geographical space are poorly known. We hypothesize that competition would be higher for influenza viruses sharing the same host than those sharing different hosts (Host Barrier Hypothesis), or for influenza viruses with a higher cross-region transmission intensity than those...

Data from: TAS2R20 variants confer dietary adaptation to high-quercitrin bamboo leaves in Qinling giant pandas

Xiangxu Hu, Guan Wang, Lei Shan, Shuyan Sun, Yibo Hu & Fuwen Wei
Sensitivity to bitter tastes provides animals with an important means of interacting with their environment and thus, influences their dietary preferences. Genetic variants encoding functionally distinct receptor types contribute to variation in bitter taste sensitivity. Our previous study showed that two nonsynonymous sites, A52V and Q296H, in the TAS2R20 gene are directionally selected in giant pandas from the Qinling Mountains, which are speculated to be the causative base-pair changes of Qinling pandas for the higher...

Data from: Native drivers of fish life history traits are lost during the invasion process

Rodolphe Gozlan, Eva Zahorskae, Emira CHERIF, Takashi Asaeda, Robert Britton, Cha-Ho Chang, To Hong, Rafael Miranda, Jiri Musil, Meta Povz, Serhan Tarkan, Elena Tricarico, Tricia Trichkova, Hugo Verreycken, Andrej Weiperth, Andrej Witkowski, Lluis Zamora, Irene Zweimuller, Ya-Hui Zhao, Hamid Esmaeili & Marine Combe
Rapid adaptation to global change can counter vulnerability of species to population declines and extinction. Theoretically, under such circumstances both genetic variation and phenotypic plasticity can maintain population fitness, but empirical support for this is currently limited. Here, we aim to characterise the role of environmental and genetic diversity, and their prior evolutionary history (via haplogroup profiles) in shaping patterns of life history traits during biological invasion. Data were derived from both genetic and life...

Biomassess of functional groups and ecosystem parameters predicted by ecosim models of Lake Dianchi

Xueqin Liu
Understanding the relative importance of multiple stressors is valuable to prioritize conservation and restoration measures. Yet, the effects of multiple stressors on ecosystem functioning remain largely unknown in many freshwaters. Here, we provided a methodology combining ecosystem modelling with linear regression to disentangle the effects of multiple stressors on matter flow, an important ecosystem function. Treating a shallow lake as the model ecosystem, we simulated matter flow dynamics during 1950s-2010s with different combinations of stressors...

Surprising roles of climate in regulating flowering phenology in a subtropical ecosystem

Zhuqiu Song, Yanjun Du & Zhongliang Huang
This dataset contains data from the paper: “Song, Z., Du, Y., Primack, R.B., Miller-Rushing, A.J., Ye, W., Huang, Z. (2021) Surprising roles of climate in regulating flowering phenology in a subtropical ecosystem. Ecography. https://doi.org/10.1111/ecog.05629”. This phenological data set included a total of 1892 collections, representing 105 native species, belonging to 76 genera of 42 families, and spanning a 105-year period from 1911 to 2015. This dataset contained 1540 herbarium specimens (81%, 1911−2012) and 352 photographs...

Data from: Trait hierarchies are stronger than trait dissimilarities in structuring spatial co-occurrence patterns of common tree species in a subtropical forest

Deyi Yin, Yu Liu, Qing Ye, Marc Cadotte & Fangliang He
1. The dissimilarity and hierarchy of trait values that characterize niche and fitness differences, respectively, have been increasingly applied to infer mechanisms driving community assembly and to explain species co-occurrence patterns. Here, we predict that limiting similarity should result in the spatial segregation of functionally similar species, while functionally similar species will be more likely to co-occur either due to environmental filtering or competitive exclusion of inferior competitors (hereafter hierarchical competition). 2. We used a...
