Effects of experimental warming on vegetative and reproductive characters of P. viviparaum in the Qinghai-Tibet Plateau
<p>This dataset contains data from a simulated warming experiment described in the paper: "Zhang, C., Li, XT., and An, YM. Effects of experimental warming on vegetative and reproductive growth of <em>Polygonum viviparaum</em> in the Qinghai-Tibet Plateau. Nordic Journal of Botany. DOI: 10.1111/njb.03157". </p> <p>The experiment investigated <i>Polygonum viviparaum</i>, a perennial herb distributed widely in arctic and alpine regions, under two different levels of experimental warming treatments to examine effects of warming on its vegetative and reproductive growth. Two types of open top chambers (OTCs), large and small, were used to generate lower and higher warming levels.</p> <p>The dataset consists of the vegetative and reproductive characters of <i>P. viviparaum</i> in control plots, large OTCs and small OTCs. The characters include plant height, leaf number, length of the longest leaf, flower diameter, bulbil length, number of flowers per spike, number of bulbils per spike, flower proportion, dry weight of stem and leaves, dry weight of flowers per spike, dry weight of bulbils per spike, reproductive allocation and bulbil germination rate.</p> <p>Main results of the experiment are that (1) the increased temperature promoted both vegetative and reproductive growth of <em>P. viviparaum</em>, but there was a significant trade-off between them. Decreased reproductive allocation under warming suggested that more available resources were devoted to vegetative growth, resulting in increased plant height, leaf number and length of the longest leaf; (2) After warming, the number and dry weight of flowers per spike decreased while the number and dry weight of bulbils per spike increased, indicating more investment to asexual reproduction over sexual reproduction in <em>P. viviparaum</em>; (3) The increase of warming further strengthened the above variation trends of vegetative and reproductive growth of <em>P. viviparaum</em>.</p>

An intra-annual 30-m dataset of small lakes of the Qilian Mountains, northeast of the Qinghai–Tibet Plateau, for the period 1987-2020
<p>Using Google Earth Engine platform and 13,297 Landsat TM/ETM+/OLI images, we released an intra-annual 30-m dataset of small lakes with different water body frequency thresholds (0%, 25%, 50%, 75%, 100%) of the Qilian Mountains region of the Tibetan Plateau from 1987 to 2020, containing 8 attributes: code, perimeter (km), area (km<sup>2</sup>), latitude, longitude, elevation (m), area error, relative error (%), and subregion. Our published dataset can provide support for small lakes studies across the Tibetan Plateau and other alpine regions of the world.

FIGURE 5. Phylogenetic tree generated by Bayesian Inference based on the data of the nuclear ITS2. Posterior probabilities> 0.5 are indicated in front of the nodes. The grey branches indicate outgroup. The red font indicates the new species.

FIGURE 4 in Integrative taxonomy of a new species of Rhyacodrilus (Annelida: Clitellata: Rhyacodrilinae) from Tibet Plateau rivers, with a preliminary assessment of its phylogenetic position
FIGURE 4. Phylogenetic tree generated by Bayesian Inference based on concatenated data of three loci (16S rDNA+COI+ITS2). Posterior probabilities> 0.5 are indicated in front of the nodes. Grey branches indicate outgroups. The red font indicates the new species. Nai, Naidinae; Rhy, Rhyacodrilinae; Pha, Phallodrilinae; Tub, Tubificinae; Lim, Limnodriloidinae; Opi, Opistocystinae; Pri, Pristininae. The subfamilial position of Heronidrilus and Bothrioneurum in Rhyacodrilinae is questionable and therefore put in quotation marks.
