title: Non-random distribution of ungulate salt licks relative to distance from North American oceanic margins

description: Aim: Terrestrial deposition of aerosol marine sodium declines with
 distance from coastlines. Salt deprivation in vertebrate herbivores and
 salt-seeking behaviors should hence increase with distance inland. We
 analyze published geospatial data on ungulate-patronized salt licks to
 test whether they are non-randomly distributed relative to distance from
 oceans and elevation. Location: Canada, Alaska, and the contiguous United
 States. Taxon: Cetartiodactyla (even-toed ungulates). Methods: We
 determined the land area and median elevation of 100 km increments from
 the North American coast. The null model of the expected number of licks
 within each interval was determined by the ratio of the interval’s land
 area to the total land area, multiplied by the total number of licks. We
 asked whether the number of licks further from coastlines was
 significantly higher than chance. We also assessed whether licks occur
 disproportionately at higher elevations, comparing the median elevation of
 observed licks to the median elevation within each interval. Results: We
 found a strong positive relationship between salt lick patronage by
 ungulates and distance from the coast. Licks occurred significantly less
 often within, and more often beyond, 500 km inland, and at significantly
 higher elevations than would be expected by chance. Main conclusions:
 These findings indicate that the patronage of salt licks is constrained
 geographically, and that the foraging behavior of ungulates and other
 phytophagous vertebrate taxa may be influenced over large spatial scales
 by sodium availability. Salt-seeking behavior varies on a wide
 biogeographical scale across North America, with concomitant implications
 for vertebrate herbivore behavior and ecology.

title: Influence of water level management on vegetation and bird use of restored wetlands in the Montezuma Wetlands Complex

description: Active water management of wetlands promotes seed and tuber production to
 feed migrating waterfowl, but few assessments exist to determine how
 management actions influence wetland structure, vegetation, and bird
 response throughout the year. We identified effects of full water
 drawdown, partial water drawdown and passive wetlands (no active
 dewatering during the growing season) on plant communities and bird
 abundance in wetlands of the Montezuma Wetlands Complex, New York,
 May–October 2016–2018 and February–April 2017–2019. We detected few
 differences in the plant community during June, but during September we
 detected greater vegetative forage quality index for waterfowl, annual
 plant cover and seed density in full and partial drawdowns than passive
 wetlands. Bird abundance was greater in June–July in passive
 wetlands and greater in September–October in full drawdowns. During spring
 migration, duck densities were greater in full and partial drawdowns. Our
 results indicate that wetland managers should use a mix of full drawdowns
 and passive wetlands to provide habitat for the greatest diversity and
 number of birds throughout the year.

title: Desiccation stress acts as cause as well as cost of dispersal in Drosophila melanogaster

description: Environmental stress is one of the important causes of biological
 dispersal. At the same time, the process of dispersal itself can incur
 and/or increase susceptibility to stress for the dispersing individuals.
 Therefore, in principle, stress can serve as both a cause and a cost of
 dispersal. We studied these potentially contrasting roles of a key
 environmental stress (desiccation) using Drosophila melanogaster. By
 modulating water and rest availability, we asked whether: (a) dispersers
 are individuals that are more susceptible to desiccation stress, (b)
 dispersers pay a cost in terms of reduced resistance to desiccation
 stress, (c) dispersal evolution alters the desiccation cost of dispersal,
 and (d) females pay a reproductive cost of dispersal. We found that
 desiccation was a clear cause of dispersal in both sexes, as both male and
 female dispersal propensity increased with increasing duration of
 desiccation. However, the desiccation cost of dispersal was male-biased, a
 trend unaffected by dispersal evolution. Instead, females paid a fecundity
 cost of dispersal. We discuss the complex relationship between desiccation
 and dispersal, which can lead to both positive and negative associations.
 Furthermore, the sex differences highlighted here may translate into
 differences in movement patterns, thereby giving rise to sex-biased
 dispersal patterns.

 experiments on Drosophila melanogaster. In all the cases, the direct
 observations have been presented, with no processing.

title: Experimental and numerical investigation of the surface-modified treatment and aerodynamic performance of a ducted-fan impeller

description: A ducted fan is a potential solution to improve the dynamic performance of
 an Unmanned Aerial Vehicle (UAV). The impeller of the ducted fan is the
 most critical plastic part. Compared with the injection molding process,
 the Fused Deposition Modeling (FDM) process has a lower cost and shorter
 cycle time, but its roughness and lift performance are undesirable. Based
 on the hydrophobic surface treatment and the related performance research
 of the ducted fan impeller, this research aimed to improve the
 anti-impedance properties. Then, the modified surface of the impeller was
 built based on mussel-inspired mechanisms and the chemical surface-coating
 process of fan products. Experiments were conducted using a scanning
 electron microscope with an ener-gy-dispersive x-ray spectroscopy system
 (SEM-EDS), laser scanning confocal microscopy (LSCM), and a UAV dynamic
 test platform. The experimental results show that the coating resulted in
 reduced surface roughness for injection molding and FDM molding, and the
 maximum lift of the impellers manufactured by the injection molding and
 FDM methods was increased by 3.3% and 12%, respectively. Moreover, the
 effect on the integrity of this coating process on FDM was significantly
 better than on the injection molding. The numerical analysis of the
 aerodynamic performance of the impeller with different roughness reveals
 the mechanism by which the surface treatment affects the blade
 effectiveness. The CFD results show that reducing the roughness led to
 less low-energy fluid in the flow channel and reduced the turbulent
 pulsation dissipation. In addition, the reduction in the blade’s surface
 roughness decreased the boundary layer thickness and the boundary layer
 velocity. Thus, the aerodynamic performance of the impeller was optimized.

title: Thainema gen. nov. (Leptolyngbyaceae, Synechococcales): a new genus of simple trichal cyanobacteria isolated from a solar saltern environment in Thailand

description: Simple trichal types constitute a group of cyanobacteria with an abundance
 of novel, often cryptic taxa. Here, we investigated material collected
 from wet surface-soil in a saline environment in Petchaburi Province,
 central Thailand. A morphological comparison of the isolated strain with
 similar known species, as well as its phylogenetic and species
 delimitation analyses based on the combined datasets of other related
 organisms, especially simple trichal cyanobacteria, revealed that the
 material of this study represented an independent taxon. Using a
 multifaceted method, we propose that this material represents a new genus,
 Thainema gen. nov., belonging to the family Leptolyngbyaceae, with the
 type species Thainema salinarum sp. nov. This novel taxon shares similar
 ecological habitats with strains previously placed in the same lineage.

title: Functional traits explain the consistent resistance of biodiversity to plant invasion under nitrogen enrichment

description: Elton’s biotic resistance hypothesis, which posits that diverse
 communities should be more resistant to biological invasions, has received
 considerable experimental support. However, it remains unclear whether
 such a negative diversity–invasibility relationship would persist under
 anthropogenic environmental change. By using the common ragweed (Ambrosia
 artemisiifolia) as a model invader, our four-year grassland experiment
 demonstrated consistently negative relationships between resident species
 diversity and community invasibility, irrespective of nitrogen addition, a
 result further supported by a meta-analysis. Importantly, our experiment
 showed that plant diversity consistently resisted invasion simultaneously
 through increased resident biomass, increased trait dissimilarity among
 residents, and increased community weighted means of resource-conservative
 traits that strongly resist invasion, pointing to the importance of both
 trait complementarity and sampling effects for invasion resistance even
 under resource enrichment. Our study provides unique evidence that
 considering species functional traits can help further our understanding
 of biotic resistance to biological invasions in a changing environment.

title: Parasitic trophic mode of plant host affects the extent of colonization, but does not induce systematic shifts in the composition of foliar endophytic assemblages in temperate meadow ecosystems

description: 1. Foliar endophytic bacteria and fungi are increasingly being recognized
 as important drivers of plant host phenotype – affecting a wide range of
 eco-physiological processes. However, we are still lacking fundamental
 ecosystem-level knowledge about the structure, function, and inter-species
 interactions in endophytic assemblages associated with plant hosts sharing
 a common life strategy or ecological specialization. 2. In this study, we
 chose two groups of plants with contrasting physiology as model systems:
 parasites and their hosts. We assessed whether plant life history
 strategy, namely differences in nutrient acquisition and accumulation,
 plays a role in structuring above-ground microbiomes under field
 conditions. 3. We focused on the structure, colonization extent, and
 potential function of foliar endophytic bacteria and fungi in three root
 hemiparasitic species (Orobanchaceae), one stem holoparasite
 (Convolvulaceae), and their potential host plants co-occurring in
 species-rich temperate grassland ecosystems. For this purpose, we combined
 next generation amplicon sequencing with quantitative real-time PCR,
 chemical analyses of leaf tissue, and, in the case of bacteria, functional
 predictions using information deposited in available databases. 4. We
 found the foliar endophytic assemblages to be diverse, dominated by
 generalist taxa, but highly similar across all studied species. Despite of
 the highly contrasting leaf tissue chemistry in the parasitic and
 non-parasitic plant species, the parasitic trophic mode did not induce
 systematic shifts in the diversity, composition, or predicted
 biogeochemical function of the endophytic microbiomes under field
 conditions. However, compared to their potential hosts, leaves of both
 hemiparasitic and holoparasitic species harbored significantly lower
 fungal counts, estimated as ß-actin gene copies ng DNA-1, which suggests
 that parasitic plants may possess mechanisms to regulate the extent of
 colonization by endophytic fungi.
description: We have collected the leaves of (shoots in one case) of 12
 different plant species from 10 different families, growing at 8 distinct
 locations, mostly in six replicates. These included three hemiparasitic
 plant species and one holoparasitic plant, along with their non-parasitic
 potential hosts. Leaves were surface sterilized,
 homogenized, DNA extracted, bacterial and fungal DNA amplified by PCR, and
 amplicons sequenced on the Illumina platform. Bacterial and fungal
 presence was quantified by qPCR. Aliquotes of the leaf material were used
 for detailed analyses of tissue chemistry using ICP-MS.
description: There are missing tissue chemistry values in samples from 2
 locations, not enough material was left due to diffuculty in extracting
 enough DNA and the neccessity to repeat the extractions, which used up
 most of the sample. These samples are clearly marked in the
 tables.

title: Scale dependence of drilling predation in the Holocene of the northern Adriatic Sea across benthic habitats and nutrient regimes

description: Predation has strongly shaped past and modern marine ecosystems, but the
 scale dependency of patterns in drilling predation, the most widely used
 proxy for predator-prey interactions in the fossil record, is a matter of
 debate. To assess the effects of spatial and taxonomic scale on temporal
 trends in the drilling frequencies (DF), we analyzed Holocene molluscan
 assemblages of different benthic habitats and nutrient regimes from the
 northern Adriatic shelf in a sequence stratigraphic context. Although it
 has been postulated that low predation pressures facilitated the
 development of high-biomass epifaunal communities in the eastern,
 relatively oligotrophic portion of the northern Adriatic shelf, DFs
 reaching up to 30-40% in the studied assemblage show that drilling
 predation levels are comparable to those typical of Late Cenozoic
 ecosystems. DFs tend to increase from the transgressive systems tract
 (TST) into the highstand systems tract (HST) at the local scale,
 reflecting an increase in water depth by 20-40 m and a shift from
 infralittoral to circalittoral habitats over the past 10,000 years. As
 transgressive deposits are thicker at shallower and highstand deposits are
 thicker at deeper locations, a regional increase in DFs from TST to HST is
 evident only when these differences are accounted for. The increase in DF
 towards the HST can be recognized at the level of total assemblages,
 classes and few abundant and widespread families, but it disappears at the
 level of genera and species because of their specific environmental
 requirements, leading to uneven or patchy distribution in space and time.

title: Data from: Systematics of Mukdenia and Oresitrophe (Saxifragaceae): Insights from genome skimming data

description: Oresitrophe and Mukdenia (Saxifragaceae) are epilithic sister genera used
 in traditional Chinese medicine. However, the taxonomy of Mukdenia,
 especially of M. acanthifolia, has been controversial. Genome skimming of
 M. acanthifolia and M. rossii, including three individuals for each
 species is reported and complete plastomes, partial mitogenomes and
 ETS/ITS sequences were assembled using these data. Their plastomes ranged
 from 156,341 bp to 157,018 bp in length and had similar structural
 characteristics and gene content of other flowering plants. These genomes
 were typically quadripartite, comprising 113 unique genes (79 protein
 coding genes, 30 tRNAs and 4 rRNAs). Comparative analysis showed that the
 plastomes of Mukdenia and Oresitrophe were relatively conservative,
 reflecting the genome size and structure, gene contents, RNA editing sites
 and codon usage. Five plastid regions that were hotspots of change
 (trnH-psbA, psbC-trnS, trnM-atpE, petA-psbJ and ccsA-ndhD) were identified
 within Mukdenia, and six regions (trnH-psbA, petN-psbM, trnM-atpE,
 rps16-trnQ, ycf1 and ndhF) contained a higher number of species-specific
 parsimony-informative sites that can serve as potential DNA barcodes for
 species identification. To infer phylogenetic relationships between
 Mukdenia and Oresitrophe, we combined our data with published data based
 on three different datasets. The monophyly of each species (O. rupifraga,
 M. acanthifolia and M. rossii) and the inferred topology ((M. rossii, M.
 acanthifolia), O. rupifraga) were well supported in trees reconstructed
 using the complete plastomes, but M. acanthifolia and M. rossii did not
 form separate clade in the ETS+ITS data. We found low recovery of genes in
 the Angiosperms 353 target enrichment panel from our unenriched genome
 skimming data. Hybridization or incomplete lineage sorting may be the
 cause of discordances between the trees reconstructed from plastid and
 nuclear data. The results from this study suggest that M. acanthifolia
 should be treated as a distinct species.

title: Estimating biodiversity using symbolic meta analysis

description: Global species richness is a key biodiversity metric. Concerns continue to
 grow over its decline due to overexploitation and habitat destruction by
 humans. Despite recent efforts to estimate global species richness, the
 resulting estimates have been highly uncertain and often logically
 inconsistent. Estimates lower down either the taxonomic or geographic
 hierarchies are often larger than those above. Further, these estimates
 have been typically represented in a wide variety of forms, including
 intervals (a, b), point estimates with no uncertainty, and point estimates
 with either symmetrical or asymmetrical bounds, making it difficult to
 combine information across different studies. Here, we develop a Bayesian
 hierarchical approach to estimate global species richness (we estimate
 22.02m species; 95% HPD interval (10.43m, 35.28m)) that combines 50
 estimates from published studies. The data mix of intervals and point
 estimates are reconciled using techniques from symbolic data analysis.
 This approach allows us to recover interval estimates at each species
 level, even when data are partially or wholly unobserved, while respecting
 logical constraints, and to determine the effects of estimation on the
 whole hierarchy of obtaining future estimates for particular taxa at
 various levels in the hierarchy.
