Data from: Will climate change cause the global peatland to expand or contract? Evidence from the habitat shift pattern of Sphagnum mosses
<p><span>Peatlands play a crucial role in the global carbon cycle. <em>Sphagnum</em></span><span> mosses (</span><span>peat mosses) are considered to be the peatland ecosystem engineers and contribute to the carbon accumulation in the peatland ecosystems. As cold-adapted species, the dominance of <em>Sphagnum</em> mosses in peatlands will be threatened by climate warming. The response of <em>Sphagnum</em> mosses to climate change is closely related to the future trajectory of carbon fluxes in peatlands. However, the impact of climate change on the habitat suitability of <em>Sphagnum</em> mosses on a global scale is poorly understood. To predict the potential impact of climate change on the global distribution of <em>Sphagnum</em> mosses, we used the MaxEnt model to predict the potential geographic distribution of six <em>Sphagnum</em> species that dominate peatlands in the future (2050 and 2070) under two greenhouse gas emission scenarios (SSP1-2.6 and SSP5-8.5). The results show that the mean temperature of the coldest quarter, precipitation of the driest month, and topsoil calcium carbonate are the main factors affecting the habitat availability of <em>Sphagnum</em> mosses. As the climate warms,<em> Sphagnum</em> mosses tend to migrate northward. The suitable habitat and abundance of <em>Sphagnum</em> mosses increase extensively in the high-latitude boreal peatland (north of 50° N) and decrease on a large scale beyond the high-latitude boreal peatland. The southern edge of boreal peatlands would experience the greatest decline in the suitable habitat and richness of <em>Sphagnum</em> mosses with the temperature rising, and would be a risk area for the transition from carbon sink to carbon source. The spatial-temporal pattern changes of <em>Sphagnum</em> mosses simulated in this study provide a reference for the development of management and conservation strategies for <em>Sphagnum</em> bogs.</span></p>

Thrombin induces myometrial contraction Endocrinology Video 1
<p>This video is supplementary file of our manuscript of "Thrombin Activates Myosin Light Chain and Induces Cyclooxygenase-2 in Human Myometrial Cells: Progesterone Ameliorates It" by Nishimura and Mogami. </p> <p>Human primary myometrial cells were seeded on a plastic dish. Myometrial cells were treated with 4 U/ml of thrombin (left panel) or PBS (right panel). Images were acquired every minute for a period of 120 min using live-cell imaging system (Olympus IX71N microscope with DP71 camera). Images were then assembled into one frame and produced one 12-second movie (x600 accelerated) using Mac Preview and iMovie (Apple). </p>

Mating preferences can drive expansion or contraction of MHC gene family
MHC-based mating rules can evolve as a way to avoid inbreeding or to increase offspring immune competence. While the role of mating preference in the MHC diversity in vertebrates has been acknowledged, its impact on individual MHC diversity has not been considered. Here, we use computer simulations to investigate how simple mating rules favouring MHC-dissimilar partners affect the evolution of the number of MHC variants in individual genomes, accompanying selection for resistance to parasites. We showed that the effect of such preferences could sometimes be dramatic. If preferences are aimed at avoiding identical alleles, e.g. under strong selection against sib-mating, the equilibrium number of MHC alleles is much smaller than under random mating. However, if the mating rule minimises the ratio of shared to different alleles in partners, MHC number is higher than under random mating. Additionally, our simulations revealed that a negative correlation between the numbers of MHC variants in mated individuals can arise from simple rules of MHC-disassortative mating. Our results reveal unexpected potential of MHC-based mating preferences to drive MHC gene family expansions or contractions and highlight the need to study the mechanistic basis of such preferences.

Invader abundance and contraction of niche breadth during replacement of a native gammarid amphipod
<p>The introduction of non-native species to new locations is a growing global phenomenon with major negative effects on native species and biodiversity. Such introductions potentially bring competitors into contact leading to partial or total species replacements. This creates an opportunity to study novel species interactions as they occur, with the potential to address the strength of inter- and intraspecific interactions, most notably competition. Such potential has often not been realized, however, due to the difficulties inherent in detecting rapid and spatially expansive species interactions under natural field conditions. The invasive amphipod crustacean <i>Gammarus pulex</i> has replaced a native species, <i>Gammarus duebeni celticus</i>, in river and lake systems across Europe. This replacement process is at least partially driven by differential parasitism, cannibalism and intraguild predation, but the role of interspecific competition has yet to be resolved. Here, we examine how abundance of an invasive species may affect spatial niche breadth of a native congeneric species. We base our analyses of niche breadth on ordination and factor analysis of biological community and physical parameters, respectively, constituting a summative, multidimensional approach to niche breadth along environmental gradients. Results derived from biological and environmental niche criteria were consistent, although interspecific effects were stronger using the biological niche approach. We show that the niche breadth of the native species is constrained as abundance of the invader increases, but the converse effect does not occur. We conclude that the interaction between invasive <i>G. pulex </i>and native <i>G. d. celticus</i> under natural conditions is consistent with strong interspecific competition whereby a native, weaker competitor is replaced by a superior invasive competitor. This study indicates a strong role of interspecific competition, alongside other known interactions such as differential intraguild predation, in rapid and expansive species replacements following biological invasions.</p>
