Data for: Giant babax helpers claim excess immediate reward in barren high-altitude habitat

Bo Du
In cooperatively breeding species, helpers take higher risk of getting deficit than dominant breeders because of the time-lag between helping and rewarding. Helpers can deal with the risk by curtailing investment or claiming immediate rewards in the cooperation. Given that dominant breeders may rely largely on the aids of helpers in raising their offspring under barren conditions, it can be hypothesized that helpers are more likely to adopt these two adaptive strategies in a barren...

The data was collected in the northeastern Qinghai-Tibetan Plateau, Qinghai Province, China (101° 18′ 57″ E, 37° 36′ 50″ N; 3 221 m a.s.l.) in 2019 and 2020, including the species-specific growth allometry (scaling exponent and intercept) fitted by the allometric equation under each treatment in a population-level experiment, i.e., control, fungicide application, neighbor removal (removal), fungicide application × neighbor removal, and the community-level mean and dispersion of the growth allometry (CWM and FDis of...

Responses of a resident group to an outsider in the blue-breasted quail: a paradigm for studying social resettlement of dispersers

Bo Du, Shumei Zi, Lifang Gao, Xiaoxue Chen, Qian Wang, Fangyuan Liu & Jianchuan Li
Dispersal is an individual life history trait that can influence the ecological and evolutionary dynamics of both the source and recipient populations. Current studies of animal dispersal have paid little attention to how the responses of residents in a recipient population affect the social resettlement of dispersers into a new habitat. We addressed this question in the blue-breasted quail Synoicus chinensis by designing an outsider introduction experiment to simulate a scenario of interaction between residents...

Data from: Nitrogen enrichment and warming shift community functional composition via distinct mechanisms: the role of intraspecific trait variability and species turnover

Xiaoyi Wang, Xuebin Yan, Kailing Huang, Xi Luo, Yuanyuan Zhang, Luyao Zhou, Fei Yang, Xiaohong Xu, Xianhui Zhou, Kechang Niu & Hui Guo
1. Global change factors may shift community functional composition by driving species turnover (species occurrence and species relative abundance) and intraspecific trait variability. However, their relative contribution in determining the functional response of community to global change, especially nitrogen enrichment and warming, remains unclear. 2. We conducted a fully factorial field experiment in a Tibetan alpine meadow to examine responses of plant community functional composition to nitrogen enrichment and warming by quantifying seven plant functional...

Data from: Does pH matter for ecosystem multifunctionality? An empirical test in a semi-arid grassland on the Loess Plateau

Yanan Wei, Jing Xin, Fanglong Su, Zhen Li, Fuwei Wang & Hui Guo
Date of data collection: 2016-2018 Geographic location of data collection: Guyuan, Ningxia, China (106°23′E, 36°15′N) These data were generated to (i) investigate the responses of soil properties, biological communities and multifunctionality to decreased soil pH; (ii) determine the potential biotic and abiotic pathways that soil pH may drive multifunctionality. In 2016, a 17 m × 40 m semi-arid grassland plot with an initial pH value of 8.05 and uniform vegetation was selected. The experiment was...

Grazing changes the direction of direct effect of shrubs on nematode communities but suppresses indirect effects through microbial pathways

Hanwen Cui, Ziyang Liu, Jingwei Chen, Jiajia Wang, Hongxian Song, Sa Xiao, Xiaoli Yang, Xiangtai Wang, Yajun Wang, Xi Kou, Lihua Meng, Kun Liu, Shuyan Chen, Lizhe An & Uffe Nielsen
Abstract It is well established that dominant plants shape belowground communities, which in turn influence ecosystem functioning. Similarly, herbivores affect belowground communities through physical disturbance and redistribution of organic inputs, but also through their interactions with the plants themselves. However, we know little about how grazing moderates effects of dominant plants on belowground organisms. We established a three-year removal experiment in a grazed and an ungrazed alpine meadow on the Qinghai-Tibet plateau to explore how...

Data from: A migratory divide spanning two continents is associated with genomic and ecological divergence

Sheela Turbek, Drew Schield, Elizabeth Scordato, Andrea Contina, Xin-Wei Da, Yang Liu, Yu Liu, Emilio Pagani-Núñez, Qing-Miao Ren, Chris Smith, Craig Stricker, Michael Wunder, David Zonana & Rebecca Safran
Migratory divides are contact zones between breeding populations with divergent migratory strategies during the non-breeding season. These locations provide an opportunity to evaluate the role of seasonal migration in the maintenance of reproductive isolation, particularly the relationship between population structure and features associated with distinct migratory strategies. We combine light-level geolocators, genomic sequencing, and stable isotopes to investigate the timing of migration and migratory routes of individuals breeding on either side of a migratory divide...

Adverse effects of remdesivir, hydroxychloroquine, and lopinavir/ritonavir when used for COVID-19: systematic review and meta-analysis of randomized trials

Anila Qasim, Ariel Izcovich, Reed Siemieniuk, Jessica Bartoszko, Long Ge, Dena Zeraatkar, Elena Kum, Assem Khamis, Bram Rochwerg, Thomas Agoritsas, Derek Chu, Shelley McLeod, Reem Mustafa, Per Vandvik & Romina Brignardello-Petersen
Background: To summarize specific adverse effects of remdesivir, hydroxychloroquine, and lopinavir/ritonavir in patients with COVID-19. Methods: We searched 32 databases through 27 October 2020. We included randomized trials comparing any of the drugs of interest to placebo or standard care, or against each other. We conducted fixed-effects pairwise meta-analysis and assessed the certainty of evidence using the GRADE approach. Results: We included 16 randomized trials which enrolled 8226 patients. For most interventions and outcomes the...

Religious celibacy brings inclusive fitness benefits

Alberto J. C. Micheletti, Erhao Ge, Liqiong Zhou, Yuan Chen, Hanzhi Zhang, Juan Du & Ruth Mace
The influence of inclusive fitness interests on the evolution of human institutions remains unclear. Religious celibacy constitutes an especially puzzling institution, often deemed maladaptive. Here, we present sociodemographic data from an agropastoralist Buddhist population in western China, where parents sometimes sent a son to the monastery. We find that men with a monk brother father more children, and grandparents with a monk son have more grandchildren, suggesting that the practice is adaptive. We develop a...

Niche conservatism limits the distribution of Medicago in the tropics

Yingbo Yang, Zhenghan Bian, Guangpeng Ren, Jianquan Liu & Nawal Shrestha
The increase in species number from poles to the equator is one of the most fundamental patterns in ecology. Although several hypotheses have been proposed, there is a lack of consensus on the mechanisms underlying this pattern. While most hypotheses provide plausible explanation for high tropical diversity of tropical clades, it is unclear if similar mechanisms drive the diversity of extra-tropical clades. Here, we investigated the environmental drivers influencing the diversity pattern of a Mediterranean...

Monks relax sibling competition over parental resources in Tibetan populations

Liqiong Zhou, Erhao Ge, Alberto Micheletti, Yuan Chen, Juan Du & Ruth Mace
Why parents in some societies induce some of their sons to become religious celibates is an evolutionary puzzle. Some have speculated that this might be associated with brother competition for family resources. However, the behavioral ecology of monks and the possible links with competition between brothers remains unexplored. Here, we use demographic data from Amdo Tibetan agropastoralists in western China to evaluate what factors determine the probability of becoming a monk and explore the possible...

Intra- and interspecific variability of specific leaf area mitigate the reduction of community stability in response to warming and nitrogen addition

Mengjiao Huang, Shaopeng Wang, Xiang Liu, Ming Nie, Shurong Zhou & Yann Hautier
Global environmental changes are reducing the diversity and affecting the functioning of natural ecosystems as well as their ability to reliably provide ecosystem functions and services to mankind. Many studies have shown that a greater plant diversity can stabilize community productivity against environmental fluctuations. However, most of these studies focused on plant species richness, thus overlooking the potential role of functional traits in stabilizing community productivity against environmental fluctuations. Whether and how functional trait mean...
