title: Data from: Quantifying niche availability, niche overlap and competition for recruitment sites in plant populations without explicit knowledge of niche axes.

description: 1. Niche availability, niche overlap and competitive ability are key
 determinants of the distribution and abundance of species. However,
 quantifying each of these components is difficult because it is not always
 possible to identify or measure relevant environmental gradients (niche
 axes) along which species might partition or compete for niche space. 2.
 We describe a method that uses seed addition experiments to quantify the
 number of ‘safe-sites’ (microsites suitable for a species to recruit from
 seed) at a location and show how this method can be used to quantify niche
 availability, niche overlap and competitive ability. We illustrate our
 approach using two seed addition experiments in grassland. 3. In the first
 experiment, we added seeds of one native and two exotic grass species,
 alone and in mixture, to plots that were arrayed along a gradient of soil
 moisture availability. We show that the three species partitioned
 safe-sites, implying that all three species could locally co-occur through
 niche partitioning, in part due to different responses to moisture
 availability. 4. In the second experiment, we added seeds of three
 commonly co-occurring native grass species, alone and in mixture, to plots
 with no obvious environmental gradients. One species outcompeted two
 others for site occupancy, allowing us to quantify both the degree of
 niche overlap and the relative ability of each species to compete for
 safe-site occupancy without a priori knowledge of the niche axes. Results
 from both experiments demonstrate the fine-scales at which species can
 partition niches to facilitate co-occurrence. 5. Synthesis. By
 conceptualising a plot of ground as containing a limited number of
 microsites that are safe for the recruitment of a given species, and using
 seed addition experiments to measure both the number of safe-sites and
 degree of safe-site overlap among species, we show how niche availability,
 niche overlap and competitive ability can be quantified at fine-scales
 without a priori knowledge of niche axes. Our approach allows questions
 about niche availability and competition for shared niche space to be
 empirically tested, and to examine how these processes vary along
 environmental gradients to shape species distributions and patterns of
 co-occurrence.

title: Data from: Tree species diversity promotes litterfall productivity through crown complementarity in subtropical forests

description: 1. The role of niche complementarity for driving the positive
 biodiversity-ecosystem productivity relationship has been widely
 recognized, but there is scant evidence regarding the role of tree canopy
 structure on this relationship. Litterfall productivity is proportional to
 forest net primary productivity in natural forests, and we hypothesized
 that litterfall productivity would increase with tree species diversity
 via increased tree crown complementarity. 2. We investigated annual
 litterfall productivity, species diversity, tree crown architecture, soil
 moisture content, soil carbon content, and stand age across 28 subtropical
 forest plots in eastern Zhejiang province, China. Simple linear regression
 was used to examine bivariate relationships among rarified species
 richness, crown complementarity, total crown volume, soil moisture
 content, soil carbon content, stand age, and litterfall productivity.
 Structural equation modeling was employed to quantify the direct and
 indirect effects of species richness on litterfall productivity through
 tree crown complementarity. 3. Litterfall productivity increased with
 rarefied species richness via increasing crown complementarity rather than
 total crown volume. Species richness, crown complementarity, and
 litterfall productivity increased with soil moisture content, while crown
 complementarity and litterfall productivity increased with soil carbon
 content. Neither species richness nor crown complementarity increased with
 stand age, even though litterfall productivity increased with stand age.
 4. Synthesis. Our study provides evidence for a strong role of tree crown
 assembly in shaping ecosystem function in complex natural forests. Our
 findings suggest that crown spatial complementarity among trees operates
 mechanistically to drive the positive tree species diversity-litterfall
 productivity relationship in subtropical forests. We argue that community
 and/or ecosystem ecology would benefit from more attention to crown
 variability among coexisting tree species.

title: Data from: The development of individual differences in cooperative behaviour: maternal glucocorticoid hormones alter helping behaviour of offspring in wild meerkats

description: The phenotype of parents can have long-lasting effects on the development
 of offspring as well as on their behaviour, physiology and morphology as
 adults. In some cases, these changes may increase offspring fitness but,
 in others, they can elevate parental fitness at a cost to the fitness of
 their offspring. We show that in Kalahari meerkats (Suricata suricatta),
 the circulating glucocorticoid (GC) hormones of pregnant females affect
 the growth and cooperative behaviour of their offspring. We performed a
 3-year experiment in wild meerkats to test the hypothesis that GC-mediated
 maternal effects reduce the potential for offspring to reproduce directly
 and therefore cause them to exhibit more cooperative behaviour. Daughters
 (but not sons) born to mothers treated with cortisol during pregnancy grew
 more slowly early in life and exhibited significantly more of two types of
 cooperative behaviour (pup rearing and feeding) once they were adults
 compared to offspring from control mothers. They also had lower measures
 of GCs as they aged, which could explain the observed increases in
 cooperative behaviour. Because early life growth is a crucial determinant
 of fitness in female meerkats, our results indicate that GC-mediated
 maternal effects may reduce the fitness of offspring, but may elevate
 parental fitness as a consequence of increasing the cooperative behaviour
 of their daughters.

title: Data from: Ultrasonic-enhanced replacement of lead in lead hydrometallurgy process from lead leaching solution

description: In this paper, ultrasonic enhanced replacement of lead by zinc in lead
 leaching solution was studied. The effects of reaction time, rotational
 speed, temperature, concentration of leaching solution and the ratio of
 the surface area of the zinc plate immersed in the leaching solution to
 the volume of leaching solution (S:V) were studied under both conventional
 and ultrasonic conditions. The optimum ultrasonic assisted replacement
 conditions were as follows: the S:V of 0.04 (4cm2/100ml), reaction
 temperature of 30 °C, replacement time of 30 min, and the concentration of
 leaching solution is 5 g/L, leading to the replacement rate of lead is
 94.84%. Compared with conventional replacement process, the reaction time
 of ultrasonic enhanced substitution could be reduced to one half, and the
 demand of reaction temperature, leaching solution concentration and other
 conditions was decreased accordingly. Introducing ultrasonic into the
 replacement reaction is promising to reduce the energy consumption in
 hydrometallurgical industry also caters to the demand of environment
 protection.

title: Data from: Investigation for the influence mechanism of rock damage on rock fragmentation and cutting performance by the discrete element method

description: Rock damage is one of the key factors in the design and model choice of
 the mining machinery. In this paper, the influence of rock damage on rock
 fragmentation and cutting performance was studied using PFC2D. In PFC2D
 software, it is feasible to get rock models with different damage factors
 by reducing the effective modulus, tensile and shear strength of bond by
 using the proportional factors. A linear relationship was obtained between
 the proportion factor and damage factor. Furthermore, numerical
 simulations of rock cutting with different damage factors were carried
 out. The results show that with the increase of damage factor, the rock
 cutting failure mode changes from tensile failure to brittle failure,
 accompanied by the propagation of macro crack, the formation of large
 debris and a notable decrease in the peak cutting force. The mean cutting
 force is negatively correlated with the damage factor. Besides, the
 instability of cutting force was evaluated by the fluctuation index (FI)
 and the pulse number (PN) of unit displacement. It is found that the
 cutting force is quite stable when the damage factor is 0.3, which
 facilitates the reliability of cutting machines. Finally, the cutting
 energy consumption of rock cutting with different damage factors was
 analyzed. The results reveal that the increase of damage factor can raise
 the rock cutting efficiency. The aforementioned findings play a
 significant role in the development of assisted rock-breaking technologies
 and the design of cutting head layout of mining machinery.

title: Data from: “Meiotic genes” are constitutively expressed in an asexual amoeba and are not necessarily involved in sexual reproduction

description: The amoebae (and many other protists) have traditionally been considered
 as asexual organisms but suspicion has been growing that these organisms
 are cryptically sexual or are at least related to sexual lineages. This
 contention is mainly based on genome studies in which the presence of
 “meiotic genes” has been discovered. Using RNA-seq (next generation
 shotgun sequencing, identifying and quantifying the RNA species in a
 sample), we have found that the entire repertoire of meiotic genes is
 expressed in exponentially growing Acanthamoeba and we argue that these so
 called meiotic genes are involved in the related process of homologous
 recombination in this amoeba. We contend that they are only involved in
 meiosis in other organisms that indulge in sexual reproduction and that
 homologous recombination is important in asexual protists as a guard
 against the accumulation of mutations. We also suggest that asexual
 reproduction is the ancestral state.

title: Data from: The direction aftereffect is a global motion phenomenon

description: Prior experience influences visual perception. For example, extended
 viewing of a moving stimulus results in the misperception of a subsequent
 stimulus’s motion direction – the direction aftereffect (DAE). There has
 been an on-going debate regarding the locus of the neural mechanisms
 underlying the DAE. We know the mechanisms are cortical, but there is
 uncertainty about where in the visual cortex they are located – at
 relatively early local motion processing stages, or at later global motion
 stages. We used a unikinetic plaid as an adapting stimulus, then measured
 the DAE experienced with a drifting random dot test stimulus. A unikinetic
 plaid comprises a static grating superimposed on a drifting grating of a
 different orientation. Observers cannot see the true motion direction of
 the moving component; instead they see pattern motion running parallel to
 the static component. The pattern motion of unikinetic plaids is encoded
 at the global processing level – specifically, in areas MT and MST – and
 the local motion component is encoded earlier. We measured the direction
 aftereffect as a function of the plaid’s local and pattern motion
 directions. The DAE was induced by the plaid’s pattern motion, but not by
 its component motion. This points to the neural mechanisms underlying the
 DAE being located at the global motion processing level, and no earlier
 than area MT.

title: Data from: Loss of biotic resistance and high propagule pressure promote invasive grass-fire cycles

description: 1. The spread of invasive grasses across Earth are modifying fire cycles
 resulting in state changes in arid ecosystems. Disturbance, biotic
 resistance of native biological communities and propagule pressure, are
 likely important factors influencing the spread of invasive grasses and
 their influence on changing fire regimes. 2. Over a five-year period
 (2011-2016), we tested how the potential loss of biotic resistance of
 native plant and native rodent communities related to fire and rodent
 exclusion treatments, in concert with increased propagule pressure
 affected the establishment of Bromus tectorum L. (cheatgrass) and the
 spread of secondary fires. 3. Our study results suggest that native plant
 and native rodent communities contribute to biotic resistance against
 cheatgrass invasion and that fire and high propagule pressure act to
 diminish biotic resistance by native communities. Five years into the
 study, cheatgrass establishment was 11-fold greater in burned plots than
 in unburned plots (with native plant communities still intact), 2.4-fold
 greater in rodent exclusion plots than rodent access plots, and 1.8-fold
 greater with increased propagule pressure. At the start of the experiment
 in 2011 and into 2012 there was very little cheatgrass in the experimental
 blocks (&lt;1 plant m-2). However, by 2016, burned-rodent excluded
 plots were fully invaded (1625 stems m-2). High propagule pressure
 released cheatgrass from biotic resistance of rodent communities in
 post-fire conditions but had minimal effects on the biotic resistance of
 native plant communities in unburned plots. Fire in combination with
 either rodent exclusion or high cheatgrass propagule pressure produced
 higher density cheatgrass stands that were positively correlated with the
 spread of secondary fires that are characteristic of invasive grass-fire
 cycles. 4. Synthesis. Loss of native plant cover or reduction in rodent
 populations due to fire, extreme climatic events or disease outbreaks,
 which are increasing with human activity, may provide windows of
 opportunity for invasive grasses to escape biotic resistance and reinforce
 invasive grass-fire cycles.

title: Data from: Relevance of heterokaryosis for adaptation and azole-resistance development in Aspergillus fumigatus

description: Aspergillus fumigatus causes a range of diseases in humans, some of which
 are characterized by fungal persistence. A. fumigatus, being a generalist
 saprotroph, may initially establish lung colonisation due to its
 physiological versatility and subsequently adapt through genetic changes
 to the human lung environment and antifungal treatments. Human
 lung-adapted genotypes can arise by spontaneous mutation and/or
 recombination and subsequent selection of the fittest genotypes. Sexual
 and asexual spores are considered crucial contributors to the genetic
 diversity and adaptive potential of aspergilli by recombination and
 mutation supply respectively. However, in certain Aspergillus diseases,
 such as cystic fibrosis and chronic pulmonary aspergillosis, A. fumigatus
 may not sporulate but persist as a network of fungal mycelium. During
 azole therapy, such mycelia may develop patient-acquired resistance and
 become heterokaryotic by mutations in one of the nuclei. We investigated
 the relevance of heterokaryosis for azole-resistance development in A.
 fumigatus. We found evidence for heterokaryosis of A. fumigatus in
 patients with chronic Aspergillus diseases. Mycelium from patient-tissue
 biopsies segregated different homokaryons, from which heterokaryons could
 be reconstructed. Whereas all variant homokaryons recovered from the same
 patient were capable of forming a heterokaryon, those from different
 patients were heterokaryon-incompatible. We furthermore compared
 heterokaryons and heterozygous diploids constructed from environmental
 isolates with different levels of azole resistance. When exposed to azole,
 the heterokaryons revealed remarkable shifts in their nuclear ratio, and
 the resistance level of heterokaryons exceeded that of the corresponding
 heterozygous diploids.

title: Data from: Patterns of rangeland productivity and land ownership: implications for conservation and management

description: Rangelands cover 40-50% of the earth’s terrestrial surface. While often
 characterized by limited, yet variable resource availability, rangelands
 are vital for humans, providing numerous ecosystem goods and services. In
 the conterminous United States (CONUS) the dominant component of rangeland
 conservation is a network of public rangelands, concentrated in the west.
 Public rangelands are interspersed with private and tribal rangelands
 resulting in a complex mosaic of land tenure and management priorities. We
 quantify ownership patterns of rangeland production at multiple scales
 across CONUS and find that both total production and average productivity
 of private rangelands more than doubles that of public and tribal
 rangelands. At finer scales, private rangelands are consistently more
 productive than their public counterparts. We also demonstrate an inverse
 relationship between public rangeland acreage and productivity. While
 conserving acreage is crucial to rangeland conservation, just as critical
 are broad scale ecological patterns and processes that sustain ecosystem
 services. Across CONUS, ownership regimes capture distinct elements of
 these patterns and services, demonstrated through disparate production
 dynamics. As ownership determines the range of feasible conservation
 actions, and the technical and financial resources available to implement
 them, understanding ownership-production dynamics is critical for
 effective and sustained conservation of rangeland ecosystem services.
