Data from: The ‘plant economic spectrum’ in bryophytes, a comparative study in subalpine forestZhe Wang, Xin Liu, Maaike Y. Bader, Defeng Feng & Weikai Bao
PREMISE OF THE STUDY: Tradeoffs among functional traits of vascular plants are starting to be better understood, but it is unclear whether bryophytes possess similar tradeoffs or how trait relationships, or the ‘economic spectrum’, differ between the two groups. METHODS: We determined functional-trait values [including shoot mass per area (SMA), light-saturated assimilation rate (Amass), dark respiration rate (Rdmass), N and P concentrations (Nmass and Pmass), and photosynthetic N and P use efficiency (PNUE and PPUE)]...
Data from: Soil drainage facilitates earthworm invasion and subsequent carbon loss from peatland soilXinwei Wu, Rui Cao, Xue Wei, Xinqiang Xi, Peili Shi, Nico Eisenhauer & Shucun Sun
1. Human activities have been a significant driver of environmental changes with tremendous consequences for carbon dynamics. Peatlands are critical ecosystems because they store ~30% of the global soil organic carbon pool and are particularly vulnerable to anthropogenic changes. The Zoige peatland on the eastern Tibet Plateau, as the largest alpine peatland in the world, accounts for 1‰ of global peat soil organic carbon storage. However, this peatland has experienced dramatic climate change including increased...
Data from: Using data from related species to overcome spatial sampling bias and associated limitations in ecological niche modelingHuijie Qiao, Andrew Townsend Peterson, Liqiang Ji & Junhua Hu
1. Ecological niche modeling (ENM) is used widely to aid in conservation planning and management, often focusing on rare species characterized by the biased observations associated with restricted geographic ranges, habitat specialization, small population size, and limited natural history information. Generating reliable ENMs for such species is a challenge, however, owing to issues that arise from spatial sampling bias, such as model inaccuracy and overfitting. Here, using virtual scenarios, we assess the utility of integrating...
Data from: A new moth-preying alpine pitviper species from Qinghai-Tibetan plateau (Viperidae, Crotalinae)Jingsong Shi, Gang Wang, Xi'er Chen, Li Ding, Song Huang, Mian Hou, Jun Liu, Pipeng Li, Xi’er Chen & Yihao Fang
The Sanjiangyuan region of Qinghai-Tibetan Plateau is recognized as a biodiversity hotspot of alpine mammals but a barren area in terms of amphibians and reptiles. Here, we describe a new pit viper species, Gloydius rubromaculatus sp. n. Shi, Li and Liu, 2017 that was discovered in this region, with a brief taxonomic revision of the genus Gloydius. The new species can be distinguished from the other congeneric species by the following characteristics: cardinal crossbands on...
Data from: Domesticated honeybees facilitate interspecific hybridization between two Taraxacum congenersYouhong Peng, Yuran Dong, Haigen Xu, Xinqiang Xi, Karl J. Niklas & Shucun Sun
1. Interspecific hybridization is common in plants under natural conditions, but the ecological mechanisms underlying when and how it happens have not fully been understood. 2. Taraxacum calanthodium and T. lugubre are two herbaceous annals co-occurring in alpine meadows of the eastern Tibetan Plateau that share the same pollinators including domestic honeybees during their overlapping flowering times. Because honeybees tend to visit flowers less discriminatively when bee densities are high, we hypothesized that intense apiculture...
