Herbivore assemblage as an important factor modulating grazing effects on ecosystem carbon fluxes in a meadow steppe in northeast China
<p>A better understanding of how grazing by large herbivores, as the major land use worldwide, affects grassland carbon fluxes is critical for predicting future uptake of CO<span>2</span> in terrestrial ecosystem. Previous studies have focused on individual herbivore species; it remains poorly understood as to if and how herbivore assemblage (single- vs. mixed-species) would alter the impact of grazers on grassland carbon fluxes. Here we examined the effects of moderate grazing by different herbivore assemblages on net ecosystem CO<span>2</span> exchange (NEE), gross ecosystem productivity (GEP) and ecosystem respiration (ER) over the growing season in two types of grassland communities in a meadow steppe. We found that herbivore assemblages significantly affected NEE, and the effects varied in the two types of grassland communities. Compared to un-grazed grassland, mixed grazing of sheep and cattle increased NEE (i.e., increased CO<span>2</span> uptake) over the growing season regardless of community type, while sheep- or cattle-only grazing increased NEE in the low diversity community and decreased it in the high diversity community. Herbivore assemblages altered the NEE primarily via changing GEP. The different effects of herbivore assemblages on GEP may be attributed mainly to grazing-induced changes in soil water availability and canopy light availability. Our study indicates that mixed grazing of sheep and cattle might be an important grazing management practice to improve plant aboveground productivity and help mitigate CO<span>2</span> emissions during the growing season. It should be particularly used in diverse plant communities, where it might increase grassland carbon sequestration.</p>

Data from: Defining isoscapes in the Northeast Pacific as an index of ocean productivity
<p><b>Aim: </b>We modeled isoscapes in the Northeast Pacific using satellite-based data with the main objective of testing if isoscapes defined by a few key parameters can be used as a proxy for secondary productivity.</p> <p><b>Location: </b>Northeast (NE) Pacific; 46 – 60⁰N and 125 – 165⁰W.</p> <p><b>Time period: </b>From 1998 to 2017 (ongoing).</p> <p><b>Major taxa studied: </b>Zooplankton with a focus on large herbivores.</p> <p><b>Methods:</b> Approximately 280 summer zooplankton samples were analyzed for Carbon (δ<sup>13</sup>C) and Nitrogen (δ<sup>15</sup>N) stable isotope (SI) ratios. Environmental conditions experienced by zooplankton organisms were extracted from satellite, in situ sensor and model databases. A generalized additive model approach was used to explain the spatial variability of δ<sup>13</sup>C and δ<sup>15</sup>N values and predict isoscapes.</p> <p><b>Results: </b>Sea surface temperature (SST), sea level anomaly (SLA) and chlorophyll-<i>a</i> concentration emerged as the significant SI predictors. Modelled isoscapes reproduced patterns observed in δ<sup>13</sup>C and δ<sup>15</sup>N value distribution, such as a decrease from the coast to offshore. The contribution of eddies in enhancing local production in the open ocean was also well captured by the models. In the central part of the NE Pacific higher SI values were correlated with higher large copepod biomass measured by the North Pacific Continuous Plankton Recorder (CPR) survey. However, in the area off the coast of British Columbia (BC) high δ<sup>15</sup>N variability appeared to be associated with episodic intrusions of coastal waters demonstrating that caution is needed when interpreting sharp changes in SI ratios.</p> <p><b>Main conclusions: </b>While the mechanisms driving SI ratio variability are complex, we demonstrated that a few parameters used as a proxy for some of these major mechanisms are able to successfully produce isoscape models. This approach was proven useful to provide a qualitative estimate of the secondary production, which can be particularly valuable in a region where few data are available.</p>

Blow to the Northeast? Intraspecific differentiation of Populus davidiana suggests a northeastward skew of a phylogeographic break boundary in East Asia
<p><b><span>Aim: </span></b>There is increasing interest in the role that biological traits, and historical and biogeographic processes, play in the formation of phylogeographic patterns. An arid belt that once existed in northern China might have affected many plants, but this has yet to be untested in an arid-tolerant, wind-dispersed species. Here we tested how intrinsic and extrinsic factors have affected the phylogeography of <i><span>Populus davidiana</span></i>.</p> <p><b><span>Location: </span></b>East Asia</p> <p><b><span>Methods: </span></b>Genetic variation was surveyed across 40 populations (555 individuals) covering the Chinese range of <i><span>P. davidiana</span></i>, using 16 nuclear microsatellite loci (nSSRs) and four chloroplast fragments (cpDNA). Demographic and migration hypotheses were tested using coalescent-based approaches, and the present and past potential distributions were predicted using species distribution modelling.</p> <p><span><span><b><span>Results: </span></b>Molecular data divides <i><span>P. davidiana </span></i>into two lineages, northeastern China (NECR), and central and northern China (CNCR); however, the dividing line is around 118ºE for nSSRs, but 122ºE for cpDNA. The range and habitat of the two lineages barely overlap at present, and their ecological separation may have initiated around the Pliocene-Quaternary boundary, when major infraspecific cpDNA clades diverged. NECR and CNCR experienced postglacial northeastward and northward range shifts, respectively. Bi-directional historical gene flow was detected between NECR and CNCR for both bi-parentally inherited nSSRs and maternally inherited cpDNA. Demographic inferences suggest a severe bottleneck for CNCR and especially NECR, around the latest Pleistocene.</span></span></p> <p><b><span>Main conclusions: </span></b>The phylogeographic break within <i><span>P. davidiana</span></i> reflects the impacts of biogeographic history, climate and biological traits. Its plumed, wind-dispersed seeds might be especially significant, because prevailing southwestern spring winds may have moved the NECR-CNCR boundary further east than similar phylogenetic breaks in other species, and also moved the cpDNA boundary relative to that for nuclear markers. Biological traits, therefore, should also be considered when examining the genetic and ecological differentiation between closely related taxa.</p>
