title: Dyke demolition led to a sharp decline in waterbird diversity due to habitat quality reduction: a case study of Dongting Lake, China

description: Dongting Lake, an important wintering habitat for migratory waterbirds in
 the East Asian–Australasian Flyway, has suffered serious degradation in
 recent decades. To restore habitats for biodiversity conservation and
 flood control, 459 dykes were demolished and 14 were preserved in 2017.
 However, the direct impact of dyke demolition on wintering waterbirds was
 not comprehensively assessed. In this study, based on annual waterbird
 census and habitat data (2013/14–2020/21), we compared the differences in
 habitat areas and species composition of waterbirds in the dyke-demolished
 and preserved areas, and explored whether habitat changes caused by the
 dyke demolition were responsible for the changes in the number of species
 and percentages of waterbird individuals. The results indicate that the
 areas of water (including shallow water) and mudflat habitats
 significantly decreased, but the vegetation area significantly increased
 in the dyke-demolished areas. The species numbers and percentages of
 waterbird individuals at the community and foraging guilds levels, and the
 percentages of nine species, were higher in the dyke-preserved areas than
 those in the dyke-demolished areas. Changes in the numbers of species and
 percentages of individuals of fish eaters, insectivores, and omnivores
 positively correlated with drastic changes in the percentages of water
 habitats (including shallow water) after dyke demolition. Effective
 measures should be carried out to restore hydrological regimes, providing
 waterbirds sufficient suitable habitats with different water depths. These
 findings improve our understanding of the influence of dyke demolition on
 waterbirds and provide insights for wetland management and waterbird
 conservation. --

title: Annotation of genome of Cladopsammia gracilis (Milne Edwards and Haime, 1848)

description: Cladopsammia gracilis (Dendrophylliidae), an ahermatypic coral, was
 sampled in the Sanya Bay in the South China sea. According to skeletal
 based taxonomy, the genus Cladopsammia is characterized by its phaceloid
 growth form of corallites basally united with common coenosteum, and well
 developed Pourtales plan. With both skeletal morphology and mitochondrial
 study, our samples were identified as Cladopsammia gracilis. In the
 research, we assembled an genome. The gff and fasta files of conding
 genes, non-coding genes, repeat sequecnes were provided here.

title: Data from: Host-parasite dynamics shaped by temperature and genotype: quantifying the role of underlying vital rates

description: 1. Global warming challenges the persistence of local populations, not
 only through heat-induced stress, but also through indirect biotic
 changes. We study the interactive effects of temperature, competition and
 parasitism in the water flea Daphnia magna. 2. We carried out a common
 garden experiment monitoring the dynamics of Daphnia populations along a
 temperature gradient. Halfway through the experiment, all populations
 became infected with the ectoparasite Amoebidium parasiticum, enabling us
 to study interactive effects of temperature and parasite dynamics. We
 combined Integral Projection Models with epidemiological models,
 parameterized using the experimental data on the performance of
 individuals within dynamic populations. This enabled us to quantify the
 contribution of different vital rates and epidemiological parameters to
 population fitness across temperatures and Daphnia clones originating from
 two latitudes. 3. Interactions between temperature and parasitism shaped
 competition, where Belgian clones performed better under infection than
 Norwegian clones, mainly due to higher survival. Infected Daphnia
 populations performed better at higher than at lower temperatures, mainly
 due to an increased host capability of reducing parasite loads.
 Temperature strongly affected individual vital rates, but effects largely
 cancelled out on a population-level. In contrast, parasitism strongly
 reduced fitness through consistent negative effects on all vital rates. As
 a result, temperature-mediated parasitism was more important than the
 direct effects of temperature in shaping population dynamics. Both the
 outcome of the competition treatments and the observed extinction patterns
 support our modeling results. 4. Our study highlights that shifts in
 biotic interactions can be equally or more important for responses to
 warming than direct physiological effects of warming, emphasizing that we
 need to include such interactions in our studies to predict the
 competitive ability of natural populations experiencing global warming.

title: Tetragnatha kauaiensis genome

description: Spiders (Araneae) have a diverse spectrum of morphologies, behaviours and
 physiologies. Initial attempts to understand the genomic-basis of this
 diversity are hindered by their large, heterozygous and AT-rich genomes
 with high repeat content resulting in highly fragmented, poor-quality
 assemblies. As a result, spider genomes’ key attributes, including gene
 family evolution, repeat content, and gene function, remain poorly
 understood. Here, we used Illumina and Dovetail Chicago technologies to
 sequence the genome of the long jawed spider Tetragnatha kauaiensis,
 producing an  assembly distributed along 3,925 scaffolds with a
 N50 of ~2 Mb. Using comparative genomics tools together with other
 available spider genomes, we explore genome evolution across available
 spider assemblies. Our findings suggest that genome size variation in
 spiders is linked to the different representation and number of
 transposable elements. Using statistical tools to uncover gene-family
 level evolution, we find expansions associated with the sensory perception
 of taste, immunity and metabolism. In addition, we report strikingly
 different histories of chemosensory, venom and silk gene families, with
 the first two evolving much earlier,  affected by the ancestral
 whole genome duplication in Arachnopulmonata  (~450 million years
 ago) and exhibiting higher numbers. Silk genes, on the other hand, are
 represented in lower numbers, but have a history of putative recent
 duplications. Together, our findings reveal that spider genomes are highly
 variable and that genomic novelty may have been driven by the burst of an
 ancient whole genome duplication, followed by gene family and transposable
 element expansion.

title: The hidden half of the fine root differentiation in herbs: nonacquisitive belowground organs determine fine-root traits

description: Plants rely on roots for absorption of nutrients from the soil.
 Differences in traits of fine roots and of the root system in general thus
 underlie differences among individual species in their ability to live in
 habitats differing in nutrient status and interactions with other species.
 Here we examine to what extent structure of the root system is determined
 by whole-plant parameters, namely the expected life span of the rooting
 units (either genetic individuals or ramets in clonally growing plants)
 and the type of belowground nonacquisitive organs such as rhizomes. By
 using phylogenetic comparative techniques we confirm the existence of two
 independent directions of variation in root traits, namely fast-slow
 continuum and cooperation continuum and show that the fast-slow continuum
 is associated with the increasing lifespan of the plant's rooting
 units (from annuals and stoloniferous species through rhizomatous species
 up to nonclonal perennial species). Lifespan of the rooting unit thus
 determines a range of root traits, namely root mass fraction (proportion
 of roots from the total biomass) and root tissue density. This shared
 continuum in root traits, life span of the rooting units and the type of
 belowground nonacquisitive organs is correlated with the environment where
 the species typically occur, with fast end (annual and stoloniferous
 species) occurring in productive and disturbed, and slow end (nonclonal
 perennials) in unproductive habitats. Further, clonal species have
 slightly shallower and thinner roots as their roots are relieved from the
 transport function which is served by horizontal stemderived organs
 (stolons and rhizomes). This confirms that plant lifespan and belowground
 nonacquisitive organs must be considered as determinants for (fine) root
 traits in herbs.

title: Climatic controls on soil carbon accumulation and loss in a dryland ecosystem

description: Arid and semiarid ecosystems drive year-to-year variability in the
 strength of the terrestrial carbon (C) sink, yet there is uncertainty
 about how soil C gains and losses contribute to this variation. To address
 this knowledge gap, we embedded C-depleted soil mesocosms, containing
 litter or biocrust C inputs, within an in situ dryland
 ecosystem warming experiment. Over the course of one year, changes in
 microbial biomass and total soil organic C pools were monitored alongside
 hourly measurements of soil CO2 flux. We also developed a
 biogeochemical model to explore the mechanisms that gave rise to observed
 soil C dynamics. Field data and model simulations demonstrated that water
 exerted much stronger control on soil biogeochemistry than temperature,
 with precipitation events triggering large CO2 pulses and
 transport of litter- and biocrust-derived C into the soil profile. We
 expected leaching of organic matter would result in steady accumulation of
 C within the mineral soil over time. Instead, the size of the total
 organic C pool fluctuated throughout the year, largely in response to
 microbial growth: increases in the size of microbial biomass were
 negatively correlated with the quantity of C residing in the top 2 cm,
 where most biogeochemical changes were observed. Our data and models
 suggest that microbial responses to precipitation events trigger rapid
 metabolism of dissolved organic C inputs, which strongly limit
 accumulation of autotroph-derived C belowground. Accordingly, changes in
 the magnitude and/or frequency of precipitation events in this dryland
 ecosystem could have profound impacts on the strength of the soil C sink.

title: Patch size distribution affects species invasion dynamics in dendritic networks

description: Biological invasions are globally affecting ecosystems, causing local
 species loss and altering ecosystem functioning. Understanding how such
 biological invasions occur and succeed is thus of high priority. Both
 local properties and the spatial network structure have been shown to be
 determinants of invasion success, and the identification of spatial
 invasion hubs directly promoting invasion dynamics is gaining attention.
 Spatial dynamics, however, could also indirectly alter invasion success by
 shaping pre- invasion local community structure: in many ecosystems, such
 as riverine networks, regional properties such as patch size distribution
 are known drivers of local community structures, which themselves may
 affect the establishment success of invading species. Using microcosm
 experiments in dendritic networks, we disentangled how inherent patch size
 distribution and dispersal along specific network topologies shaped local
 resident communities, and, subsequently, affected the establishment
 success of invading species. After controlling for regional-scale effects
 of connectivity on pre-invasion diversity, we find that patch size
 distributions independently shaped pre-invasion community diversity and
 invasion success, with no direct effect of pre-invasion diversity on
 invasion success. Our results suggest that 1) landscape configuration
 plays an underestimated role in invasion success and that 2) invasion
 success should follow predictable landscape-scale patterns in riverine
 networks given non-random patch-size distribution.

title: Pivotal role of O-antigenic polysaccharide display in the sensitivity against phage tail-like particles in environmental Pseudomonas kin competition

description: Environmental pseudomonads colonize various niches including
 insect and plant environments. When invading these environments, bacteria
 are confronted with the resident microbiota. To cope with closely related
 strains they deploy narrow-spectrum weaponry such as tailocins, i.e phage
 tail-like particles. Little is known about the receptors for these
 tailocins especially among phylogenetically closely related species. Here,
 we studied the interaction between an R-tailocin from Pseudomonas
 protegens CHA0 and a targeted kin, Pseudomonas protegens Pf-5. Using
 genome-wide transposon insertion sequencing, we identified that
 lipopolysaccharides are involved in the sensitivity of Pf-5 towards the
 tailocin of CHA0. By generating Pf-5 lipopolysaccharide mutants and
 exposing them to extracted tailocin, we specified the two O-antigenic
 polysaccharides (O-PS) targeted by the tailocin. We affirmed the role of
 these O-PS through competition assays in vitro as well as in insects.
 Further, we demonstrate that O-PS are double-edge swords that are
 responsible for the sensitivity of P. protegens towards phage tail-like
 particles produced by their kin, but shield bacteria from the immune
 system of the insect. Our results shed light on the trade-off that
 bacteria are confronted with, where specific O-PS decorations can both be
 of benefit or disadvantage depending on the host environment and its
 bacterial inhabitants.

title: AI leader disclosure

description: As artificial intelligence (AI) increasingly occupies supervisory and leader roles in organizations, questions arise regarding how employees respond to AI leaders, particularly with respect to trust and job satisfaction. Although prior research has largely examined AI leadership at a conceptual level, little is known about how followers react when first encountering an AI leader. This study examines whether explicit AI leader disclosure fosters follower trust and, in turn, enhances follower job satisfaction. Drawing on social exchange theory, we employed an experimental vignette methodology with working adults who were randomly assigned to either an AI leader disclosure condition or a control condition. After reading the vignette, participants completed established and adapted measures of follower trust and job satisfaction. Results show that follower trust fully mediates the relationship between AI leader disclosure and job satisfaction. Although the direct effect of AI leader disclosure on job satisfaction was non-significant, the indirect effect through follower trust was significant. These findings suggest that transparent disclosure of an AI leader’s identity can support trust formation, which is critical for positive employee experiences. The study contributes to the emerging literature on AI in leadership by introducing AI leader disclosure as a relational practice and identifying follower trust as a key mechanism linking AI leaders to employee job satisfaction.

title: Data from: Nutritional challenges of feeding a mutualist: testing for a nutrient-toxin tradeoff in fungus-farming leafcutter ants

description: The biochemical heterogeneity of food items often yields tradeoffs as each
 bite of food tends to contain some nutrients in surplus and others in
 deficit, as well as other less palatable or even toxic compounds. These
 multidimensional nutritional challenges are likely compounded when foraged
 foods are used to provision others (e.g. offspring or symbionts) with
 different physiological needs and tolerances. We explored these challenges
 in free-ranging colonies of leafcutter ants that navigate a diverse
 tropical forest to collect plant fragments they use to provision a
 co-evolved fungal cultivar. We tested the prediction that leafcutter
 farmers face provisioning tradeoffs between the nutritional quality and
 concentration of toxic tannins in foraged plant fragments. Chemical
 analyses of plant fragments sampled from the mandibles of Panamanian Atta
 colombica leafcutter ants provided little support for a nutrient-tannin
 foraging tradeoff. First, colonies foraged for plant fragments ranging
 widely in tannin concentration. Second, high tannin levels did not appear
 to restrict colonies from selecting plant fragments with blends of protein
 and carbohydrates that maximized cultivar performance when measured with
 in vitro experiments. We also tested whether tannins expand the realized
 nutritional niche selected by leafcutter ants into high-protein dimensions
 since: 1) tannins can bind proteins and reduce their accessibility during
 digestion, and 2) in vitro experiments have shown that excess protein
 provisioning reduces cultivar performance. Contrary to this hypothesis,
 the most protein-rich plant fragments did not have highest tannin levels.
 More generally, the approach developed here can be used to test how
 multidimensional interactions between nutrients and toxins shape the costs
 and benefits of providing care to offspring or symbionts.

 in vitro fungal culture in the lab, 2) published quantification of protein
 and carbohydrate in plant samples (reference explicitly cited in the

title: Phylogeny and disparate selection signatures suggest two genetically independent domestication events of pea (Pisum L.)

description: Domestication is considered a model of adaptation that can be used to draw
 conclusions about the modus operandi of selection in natural systems.
 Investigating domestication may give insights into how plants react to
 different intensities of human manipulation, which has direct implication
 for the continuing efforts of crop improvement. Therefore, scientists of
 various disciplines study domestication-related questions to understand
 the biological and cultural bases of the domestication process. We
 employed restriction site-associated DNA sequencing (RAD-seq) of 494 Pisum
 sativum (pea) samples from all wild and domesticated groups to analyze the
 genetic structure of the collection. Patterns of ancient admixture were
 investigated by analysis of admixture graphs. We used two complementary
 approaches, one diversity based and one based on differentiation, to
 detect the selection signatures putatively associated with domestication.
 An analysis of the subpopulation structure of wild P. sativum revealed
 five distinct groups with a notable geographic pattern. Pisum abyssinicum
 clustered unequivocally within the P. sativum complex, without any
 indication of hybrid origin. We detected 32 genomic regions putatively
 subjected to selection: 29 in P. sativum ssp. sativum and three in
 P. abyssinicum. The two domesticated groups did not share regions under
 selection and did not display similar haplotype patterns within those
 regions. Wild P. sativum is structured into well-diverged subgroups.
 Although Pisum sativum ssp. humile is not supported as a taxonomic entity,
 the so-called 'southern humile' is a genuine wild group.
 Introgression did not shape the variation observed within the sampled
 germplasm. The two domesticated pea groups display distinct genetic bases
 of domestication, suggesting two genetically independent domestication
 events.
