Experimental Data for understanding melting and phase relations at the Mercury silicate mantle compositions as a function of temperature at 7 GPa
<p><span>High pressure-temperature experiments were performed at 7 GPa and 1700-2100 C using a cubic press to understand melting relations at the core-mantle boundary on Mercury. Mer8 was in the stability field of orthopyroxene whereas Mer15 first crystallized olivine. With cooling, both compositions reached a cotectic surface with olivine + orthopyroxene, followed by garnet and clinopyroxene. A sulfide phase (FeS + MgCaFeS) was present in all experiments.</span></p>
Data related to article: Shrubs exhibit competitive interactions with herbaceous plants and shape community assemblage and functional composition in alpine western Himalaya
<p>To understand the interaction between dominant shrubs and herbacous communities in the alpine region of western Himalaya, a field study was conducted along the elevation gradient (3500-5000 masl). During the field survey, we have collected population data, plant functional trait data and soil physico-chemical data from shrub undercanopy and adjacent open habitats. Relative Interaction Index and L0g ratio were calculated using the population data. Further, plant functional traits data and soil physicochemical data were utilised to understand the functional comoposition and resource availability occuring in the contrasting habitats.</p>
Data for: Sun, Ogushi, Tseng -Lepidoptera species richness and community composition in urban street trees
<p>The triple threats of climate change, habitat loss, and environmental pollution have stimulated discussion on how urban areas can be modified to both mitigate heat increases and provide habitat for wildlife such as insects. The strategy of using trees to reduce temperatures has been adopted by numerous cities. However, the majority of street trees planted around the world are non-native. Studies conducted in non-urban areas have demonstrated in comparison to native plants, non-native plants are less likely to support native insect diversity. Here we use a database approach to quantify the number of native Lepidoptera species associated with 76 of the most common street tree species planted in Vancouver, Canada. We tested the prediction that compared to non-native trees, native street trees will support a higher diversity and unique community of native Lepidoptera. As predicted, native street trees were associated with five times as many native Lepidoptera species, and the Lepidoptera communities supported by native vs. non-native street trees were distinct. There was no difference in native Lepidoptera associations between broadleaf vs. coniferous street trees. These results are consistent with studies that have used active sampling techniques to investigate insect richness on a smaller subset of native and non-native tree species. Collectively, these data provide good evidence that the planting native instead of non-native trees will help stem the loss of insect diversity in urban areas.</p>

Data from: A new tool to improve the estimates of interaction rewiring considering the whole community composition
<p>Understanding temporal dynamics in ecological networks is crucial to predicting their capability to cope with global changes. Despite this, proper quantification of network dynamics still remains a challenge. Temporal dynamics are typically studied using data of interaction networks over time, through the evaluation of interaction turnover and its two components: changes related to species turnover (species gains and losses) or rewiring (switching partners among the set of species shared over time). However, with this approach based exclusively on network data, dynamics are computed similarly for species that are truly missing from the community at a given temporal period, and for species occurring in the community but that do not interact with any other. This might lead to an underestimation of the real extent of rewiring, while overestimating the species turnover component of interaction turnover.</p> <p>We used data on 20 plant-pollinator communities to calculate interaction turnover components accounting also for the species that occurred in the communities at different temporal periods but did not appear in some of the temporal interaction networks (non-interacting species), and then compared these estimates with conventional ones. Besides, we used empirical data and simulations to evaluate the extent to which dynamics estimates were affected by sampling effort when including and excluding non-interacting species.</p> <p>As expected, disregarding the non-interacting species that occur in the communities at different temporal periods leads to the underestimation of rewiring and the overestimation of species turnover as components of interaction turnover. Effect size was moderate when independent pollinator data were included, and large when including plants or both trophic levels. Simulations indicated that, in general, considering the non-interacting species reduced biases at the time of identifying changes due to the different interaction turnover components. Accounting for non-interacting species was particularly important to reduce bias when sampling effort was low and when dynamics were calculated seasonally. Despite sampling effort effects, phenology was the main determinant of species' rewiring frequencies.</p> <p>Our approach contributes to reducing biases and improving the estimates of interaction flexibility in networks, which are necessary to comprehend the response of communities in the face of global change.</p>

Equilibrium chemical composition of impact-produced hot cloud during isentropic expansion. The initial temperature T0 is 4000 K, the initial pressure P0 is 5, 20, and 80 bar. Calculations are performed using the EQL program. Abundances of considered species are presented in molar fractions.The elemental composition of impact-produced cloud is taken as a mixture of CI chondrite, mare basalts, and ferroan anorthosite with a ratio of 1:25:25 by mass as in Berezhnoy (2013).
<p>Considered species include ions, neutral gas-phase species, and condensates. Ions are written as ...(+) (for example, Al(+)). Condensates (solids and liquids) are written as ...(c) or ...(c;...).

IODP Expedition 360 Whole-round core section composite 360 degree images
Images of the outside of hard rock whole-round sections were acquired using a linescan imager (Section Half Imaging Logger [SHIL]) and a special holder that allows each 90 degree segment of the outer surface to be positioned properly. The images were taken at a resolution of 20 lines/mm (50 micropixels). JRSO staff take these quadrant images and compile them into a side-by-side rollout photograph of the section. Composite images are available as both JPG and TIF image formats. Individual quadrant images are available as JPG images only through this report; contact the <a href="mailto:database@iodp.tamu.edu">IODP-JRSO Data Librarian</a> if quadrant TIF files (~160 MB) are needed.
