title: Arctic shrub colonization lagged peak postglacial warmth: Molecular evidence in lake sediment from Arctic Canada

description: Arctic shrubification is an observable consequence of climate change,
 already resulting in ecological shifts and global-scale climate feedbacks
 including changes in land surface albedo and enhanced evapotranspiration.
 However, the rate at which shrubs can colonize previously glaciated
 terrain in a warming world is largely unknown. Reconstructions of past
 vegetation dynamics in conjunction with climate records can provide
 critical insights into shrubification rates and controls on plant
 migration, but paleoenvironmental reconstructions based on pollen may be
 biased by the influx of exotic pollen to tundra settings. Here, we
 reconstruct past plant communities using sedimentary ancient DNA
 (sedaDNA), which has a more local source area than pollen. We additionally
 reconstruct past temperature variability using bacterial cell membrane
 lipids (brGDGTs) and an aquatic productivity indicator (biogenic silica)
 to evaluate the relative timing of postglacial ecological and climate
 changes at a lake on southern Baffin Island, Arctic Canada. The sedaDNA
 record tightly constrains the colonization of dwarf birch (Betula, a
 thermophilous shrub) to 5.9 ± 0.1 ka, ~3 ka after local deglaciation as
 determined by cosmogenic 10Be moraine dating and &gt;2 ka later than
 Betula pollen is recorded in nearby lake sediment. We then assess the
 paleovegetation history within the context of summer temperature and find
 that paleotemperatures were highest prior to 6.3 ka, followed by cooling
 in the centuries preceding Betula establishment. Together, these molecular
 proxies reveal that Betula colonization lagged peak summer temperatures,
 suggesting that inefficient dispersal, rather than climate, may have
 limited Arctic shrub migration in this region. In addition, these data
 suggest that pollen-based climate reconstructions from high latitudes,
 which rely heavily on the presence and abundance of pollen from
 thermophilous taxa like Betula, can be compromised by both exotic pollen
 fluxes and vegetation migration lags.

title: Data from: Experimental study of shear and hydraulic bonding strength between casing and cement under complex temperature and pressure conditions

description: The cement sheath plays a vital role in preventing gas channelling. It is
 important to understand the interfacial bonding between the casing and
 cement sheath when the downhole temperature and pressure change. This
 paper demonstrates the results of an experimental study to investigate the
 effect of high-temperature and high-pressure (HTHP) and their variations
 on the cement sheath interfacial bonding strength (CSIBS). An experimental
 device was developed that is used to test the shear and hydraulic bonding
 strength with the method of uniaxial compression and gas channelling. The
 results show that both temperature and pressure have a significant
 influence on the CSIBS. As the curing temperature increases with a
 constant curing time or as the curing time increases with a constant
 curing temperature, the CSIBS first increases and then converges to a
 stable value. The casing roughness has a crucial effect on the shear
 bonding strength but little effect on the hydraulic bonding strength.
 Though the CSIBS decreases obviously with the decrease in temperature, it
 undergoes little change when the temperature first increases and then
 recovers to the initial value. When the internal casing pressure decreases
 to a certain value or first increases to a certain value followed by
 recovery to the initial state, the hydraulic bonding strength tends to be
 0 MPa, which means that the interface undergoes debonding between the
 casing and cement.

title: Reappraisal of arctostylopid mammal Kazachostylops occidentalis from the late Paleocene of Kazakhstan and phylogenetic relationships within Arctostylopida

description: Kazachostylops occidentalis Nesov, 1987, based on partial maxilla and
 dentary from the upper Paleocene Zhylga locality in South Kazakhstan, is
 redescribed. A new phylogenetic hypothesis of Arctostylopida is proposed
 based on phylogenetic analysis of 26 characters and 17 taxa.
 Kazachostylops is recovered as a sister taxon to the Arctostylopinae, the
 advanced clade of Asian and North American arctostylopids characterized by
 pseudohypocone on upper molars and reduced trigonid of lower molars, with
 the ectolophid being attached labial on the trigonid. Kazachostylops
 differs from more basal arctostylopids (Asiostylops, Allostylops,
 Bothriostylops, and Wanostylops) by higher-crowned molars, M1-3 metaconule
 absent, m1-3 entoconid connected with ectolophid by entolophid, and m2
 wider than m1 and m3. Principal component analyses of the upper and lower
 dentition of arctostylopids show great distinctness of Kazachostylops from
 other members of the group. The arctostylopid taxa are reviewed, and the
 new genus Enantiostylops is erected for ‘Sinostylops’ progressus Tang and
 Yan, 1976 from the lower Eocene of China, because of uniquely concave
 parastylar area on upper molars.

title: Data from: Epiphyll specialization for leaf and forest successional stages in a tropical lowland rainforest

description: Questions The importance of tropical rainforest gap dynamics
 in biodiversity maintenance is not fully understood, in
 particular for taxa other than trees and lianas. We used epiphylls on
 rainforest leaves to study the importance of leaf- and forest-scale
 succession in determining biodiversity patterns by characterizing
 community change with leaf age in gaps and closed-forest
 habitats. We asked: 1. Do epiphylls show
 specialization for leaf and forest successional stages? 2. Can
 early and late-successional epiphyllous species be
 recognized at these two scales? 3. How do epiphyll
 presence, species richness, and cover change with leaf
 and forest successional stages?   Location Barro Colorado Island,
 Panama.   Methods Data were collected from 420 leaves, in three
 age groups and at two heights on shrubs in gaps and closed
 forest. We calculated turnover and nestedness components of
 dissimilarity to evaluate the importance of species replacement or
 accumulation during leaf and forest succession. Using
 generalized linear mixed models we determined what factors explain
 epiphyll species occurrence, richness and cover.   
 Results Closed forest contained more liverwort and lichen specialist
 species than gaps. Specialist species were identified
 for older leaves only. Dissimilarity between leaves
 within age groups was dominated by turnover within and
 between forest successional stages. Dissimilarity between leaf
 age , at the site level, was dominated by nestedness, i.e.
 species accumulation. Both in forest and
 gaps, epiphyll presence and cover increased with leaf age for all taxa except fungi, while species richness increased only for lichens.   Conclusion Early and late forest successional stages both contribute to epiphyll species richness by harboring specialized species. Among leaf successional stages, young leaves contain a mere subset of the species found on older leaves. Epiphyll communities do not follow classic succession, in the sense of changes being driven by species replacement, but are characterized by species accumulation through time.

title: Data from: Antibiotic uptake across gram-negative outer membranes: better predictions towards better antibiotics

description: Crossing the gram-negative bacterial membrane poses a major barrier to
 antibiotic development, as many small molecules that can biochemically
 inhibit key bacterial processes are rendered microbiologically ineffective
 by their poor cellular uptake. The outer membrane is the major
 permeability barrier for many drug-like molecules, and the chemical
 properties that enable efficient uptake into mammalian cells fail to
 predict bacterial uptake. We have developed a computational method for
 accurate prospective prediction of outer-membrane uptake of drug-like
 molecules, which we combine with a new medium-throughput experimental
 assay of outer membrane vesicle swelling. Parallel molecular dynamics
 simulations of compound uptake through E. coli OmpF are used to
 successfully and quantitatively predict experimental permeabilities
 measured via either outer membrane swelling or via prior liposome swelling
 measurements. These simulations are analyzed using an inhomogeneous
 solubility-diffusion model to yield predictions of permeability. For most
 polar molecules we test, outer membrane permeability also correlates well
 with whole-cell uptake. The ability to accurately predict and measure
 outer-membrane uptake of a wide variety of small molecules will enable
 simpler determination of which molecular scaffolds and which derivatives
 are most promising prior to extensive chemical synthesis. It will also
 assist in formulating a more systematic understanding of the chemical
 determinants of outer-membrane permeability.

 small-molecule permeability through OmpF porins in bacterial outer
 membranes.

 parameter files, and small molecule parameters for each small molecule

title: Data from: Genetic variability and transgenerational regulation of investment in sex in the monogonont rotifer Brachionus plicatilis

description: In cyclical parthenogens such as aphids, cladocerans and rotifers, the
 coupling between sexual reproduction and the production of resting stages
 (diapausing eggs) imposes strong constraints on the timing of sex. While
 induction of sex is generally triggered by environmental cues, the
 response to such cues may vary across individuals according to genetic and
 non-genetic factors. In this study, we explored genetic and epigenetic
 causes of variation for the propensity for sex using a collection of
 strains from a Spanish population of monogonont rotifers (Brachionus
 plicatilis) in which variation for the threshold population density at
 which sex is induced (mixis threshold) had been documented previously. Our
 results show significant variation for the mixis threshold among 20 clones
 maintained under controlled conditions for 15 asexual generations. The
 effect of the number of clonal generations since hatching of the
 diapausing egg on the mixis ratio (proportion of sexual offspring
 produced) was tested on 4 clones with contrasted mixis thresholds. The
 results show a negative correlation between the mixis threshold and mixis
 ratio, as well as a significant effect of the number of clonal generations
 since fertilization, sex being repressed during the first few generations
 after hatching of the diapausing egg.

title: Toolbox for: Teaching lab for large cohorts of undergraduates: private and social information in fish

description: A challenge in the Bachelor's studies in Biology, is to strive for a
 balance between reducing the teaching of practical scientific experiments
 to what is feasible in a short time, and teaching "real" science
 in undergraduate labs for high numbers of participants. We describe a lab
 in behavioural biology, with the primary focus on the student learning.
 However, also the underlying scientific question and the results of the
 experiment, namely the behaviour of the three-spined stickleback
 (Gasterosteus aculeatus) in a trade-off situation during foraging, is
 without a doubt timely and sufficient for scientific studies on this
 subject, and this through the experiments conducted and data collected by
 the students. The students rated this lab well and learned at the end that
 social information is certainly important, but that self-learning can be
 more important, and this not only in small fish, but also for the students
 themselves.
description: This toolbox includes all material to enable teachers in higher
 education to conduct the teaching lab as outlined in the linked article.
 The material is based on several years of teaching and improving this
 course and contains (1) a manual for preparation and training aimed at
 teachers and tutors, (2) a preparation script for students, and (3) a
 Excel-file for in-class data collection, assembly, and analysis, including
 an example dataset containing data of 96 behavioural trials of the
 experiment on feeding in sticklebacks using public versus private
 information conducted by undergraduate students of the University of
 Cologne.

title: Brain size affects responsiveness in mating behavior to variation in predation pressure and sex-ratio

description: Despite ongoing advances in sexual selection theory, the evolution of
 mating decisions remains enigmatic. Cognitive processes often require
 simultaneous processing of multiple sources of information from
 environmental and social cues. However, little experimental data exist on
 how cognitive ability affects such fitness-associated aspects of behavior.
 Using advanced tracking techniques, we studied mating behaviors of guppies
 artificially selected for divergence in relative brain size, with known
 differences in cognitive ability, when predation threat and sex-ratio was
 varied. In females, we found a general increase in copulation behavior in
 when the sex-ratio was female biased, but only large-brained females
 responded with greater willingness to copulate under a low predation
 threat. In males, we found that small-brained individuals courted more
 intensively and displayed more aggressive behaviors than large-brained
 individuals. However, there were no differences in female response to
 males with different brain size. These results provide further evidence of
 a role for female brain size in optimal decision-making in a mating
 context. In addition, our results indicate that brain size may affect
 mating display skill in male guppies. We suggest that it is important to
 consider the association between brain size, cognitive ability and sexual
 behavior when studying how morphological and behavioral traits evolve in
 wild populations.

title: Evolution of conserved noncoding sequences in Arabidopsis thaliana

description: Recent pangenome studies have revealed that a large fraction (&gt;20%)
 of the gene content within a species exhibits presence-absence variation
 (PAV). However, coding regions alone provide an incomplete assessment of
 functional genomic sequence variation at the species level. Little to no
 attention has been paid to noncoding regulatory regions in pangenome
 studies, though these sequences directly modulate gene expression and
 phenotype. To uncover regulatory genetic variation, we generated
 chromosome-scale genome assemblies for thirty Arabidopsis thaliana
 accessions from multiple distinct habitats and characterized species level
 variation in Conserved Noncoding Sequences (CNS). Our analyses uncovered
 not only evidence for PAV and Positional Variation (PosV) but that
 diversity in CNS is non-random, with variants shared across different
 accessions. Using evolutionary analyses and chromatin accessibility data,
 we provide further evidence supporting conserved and variable CNS roles in
 gene regulation. Characterizing species-level diversity in all functional
 genomic sequences may later uncover previously unknown mechanistic links
 between genotype and phenotype.

title: Historical dynamics of the demersal fish community in the East and South China Seas

description: Taiwan has a long history of fishery operations and contributes
 significantly to global fishery harvest. The East and South China seas are
 important fishing grounds with very limited public data. More efforts are
 needed to digitize and analyze historical catch rate data to illuminate
 species and community changes in this region. In this study, we digitize
 historical records of catch and effort from government fishery reports for
 nine commercial species caught by otter trawl, reported quarterly from
 1970 to 2001 from the East and South China Seas. We analyze the four
 seasons and present abundance indices, distributions and among-species
 correlations for nine commercially important species from 1970-1988 (a
 period with high fishing effort) using a multispecies spatio-temporal
 model that estimates both covariation in multispecies catch rates,
 attributed to spatial habitat preferences and environmental responses, and
 indices representing trends in abundance and distribution. We find
 substantial spatial, temporal and spatio-temporal variation in the
 distribution of fishes and season specific patterns. We conclude by
 recommending collaborative work from various adjacent countries to
 digitize historical records of fishing catch rates since more records
 would potentially address scientific disagreements regarding trends in
 abundance and distribution for commercial fishes in this region through
 comparative studies.
description: We digitized historical Taiwanese otter trawler catch-and-effort (CPUE) data in the East China Sea (Lat: 17-34.5°N, Long: 108-128.5°E), which were available from the Annual Report of Effort and Catch Statistics by Area on Taiwan Demersal Fish Fisheries published by the Fisheries Agency, Council of Agriculture, Executive Yuan, Taiwan (compiled by Dr. Shean-Ya Yeh, the Demersal Fish Research Center, Institute of Oceanography, National Taiwan University) (Fig.1a). The dataset contains: total catch weight (unit = no. cases; 1 case = 30 kg approximately) for each species in four fishing seasons each year (winter: Jan-March; spring: April-June; summer: July-Sept; fall:  Oct-Dec) and year in each of 50 grid cells (dimension 0.5° latitude by 0.5° longitude); and total fishing effort (no. hauls) in each cell in each season and year for boats of 100-200 metric tons (the primary size class participating in the fishery). Data were originally derived from logbook entries and recorded by grid.

title: Astroniumxylon, Schinopsixylon and Parametopioxylon n. gen. fossil woods from Upper Cenozoic of Argentina: Taxonomic revision, new taxon and new records

description: This paper presents new descriptions of Anacardiaceae fossil woods from
 the Ituzaingó Formation (late Cenozoic) at the Toma Vieja, Curtiembre, and
 Arroyo El Espinillo localities, Argentina. We describe eight silicified
 woods assigned to four different species in three genera, one of which,
 Parametopioxylon crystalliferum n. gen. n. sp., is new. Similarities
 between these three genera and the six Anacardiaceae species previously
 recorded from the late Cenozoic in northeastern Argentina are investigated
 using multivariate analysis techniques (correspondence and cluster
 analysis). Our study is based on thirty-three characters scored for
 seventeen fossil specimens (ten Astroniumxylon Brea, Aceñolaza et Zucol
 2001, five Schinopsixylon Lutz 1979 and two Parametopioxylon n. gen.) and
 four extant species (Astronium balansae Engl., Astronium urundeuva Engl.,
 Schinopsis balansae Engl. and Metopium sp.). Our main goal is to determine
 the wood anatomical features useful for distinguishing among these
 species. The results of the multivariate analyses support the previous
 classification where Schinopsixylon is distinguished from Astroniumxylon
 by having exclusively paratracheal axial parenchyma, ≥30% multiseriate
 rays, and multiseriate rays that are ≥5 cells wide and commonly 301–400 µm
 in height. Additionally, we propose that Schinopsixylon heckii Lutz 1979
 is synonymous with S. herbstii Lutz, 1979. A diagnostic key for the fossil
 species studied is given. Wood anatomy of Anacardiaceae fossil woods from
 Argentina (late Cenozoic) suggests a warm dry to semi-humid climate for
 this region supporting previous studies.

title: Data from: Gender diversity of editorial boards and gender differences in the peer review process at six journals of ecology and evolution.

description: Despite substantial progress for women in science, women remain
 underrepresented in many aspects of the scholarly publication process. We
 examined how the gender diversity of editors and reviewers changed over
 time for six journals in ecology and evolution (2003-2015 for four
 journals, 2007-2015 or 2009-2015 for the other two), and how several
 aspects of the peer review process differed between female and male
 editors and reviewers. We found that, for five of the six journals, women
 were either absent or very poorly represented as handling editors at the
 beginning of our dataset. The representation of women among handling
 editors increased gradually and consistently, with women making up 29% of
 the handling editors (averaged across journals) in 2015, similar to the
 representation of women as last authors on ecology papers (23% in 2015)
 but lower than the proportion of women among all authors (31%) and among
 members of the societies that own the journals (37-40%). The proportion of
 women among reviewers has also gradually but consistently increased over
 time, reaching 27% by 2015. Female editors invited more female reviewers
 than did male editors, and this difference increased with age of the
 editor. Men and women who were invited to review did not differ in whether
 they responded to the review invitation, but, of those that responded,
 women were slightly more likely to agree to review. In contrast, women
 were less likely than men to accept invitations to serve on journal
 editorial boards. Our analyses indicate that there has been progress in
 the representation of women as reviewers and editors in ecology and
 evolutionary biology, but women are still underrepresented among the
 gatekeepers of scholarly publishing relative to their representation among
 researchers.
