Data from: Sea urchins mediate the availability of kelp detritus to benthic consumers
Detritus can fundamentally shape and sustain food webs, and shredders can facilitate its availability. Most of the biomass of the highly productive giant kelp, Macrocystis pyrifera, becomes detritus that is exported or falls to the seafloor as litter. We hypothesized that sea urchins process kelp litter through shredding, sloppy feeding, and egestion, making kelp litter more available to benthic consumers. To test this we conducted a mesocosm experiment in which an array of kelp forest benthic consumers were exposed to 13C- and 15N-labeled Macrocystis with or without sea urchins, Strongylocentrotus purpuratus, present. Our results showed that several detritivore species consumed significant amounts of kelp, but only when urchins were present. Although they are typically portrayed as antagonistic grazers in kelp forests, sea urchins can have a positive trophic role, capturing kelp litter before it is exported and making it available to a suite of benthic detritivores.
Data from: Infrapopulation size and mate availability influence reproductive success of a parasitic plant
1. Aggregated distributions of parasite individuals across host individuals are nearly ubiquitous among parasitic taxa. The size and sex ratio of the population of one parasite species infecting a single host (hereafter "infrapopulation") can influence parasite fitness through intraspecific competition, mate availability, and the ability to attract vectors for transmission of parasite propagules. Competition for both resources and for pollen and seed vector services may limit reproductive success (pollen receipt, fruit production, and seed dispersal) in large infrapopulations of parasitic plants, while mate limitation or reduced ability to attract vectors may limit this success in small infrapopulations. 2. Using a dioecious parasitic plant, desert mistletoe (Phoradendron californicum), we experimentally removed reproductive tissue from male parasites in whole infrapopulations to test for independent effects of infrapopulation size and within-host mate availability on female fitness. As desert mistletoe requires both pollen and seed vectors for successful reproduction, the species provides the opportunity to test how infrapopulation characteristics affect multiple components of parasite fitness. 3. We found that insect-mediated pollen receipt decreased for parasites on treated hosts, consistent with within-host mate limitation. Additionally, the relationship between mate availability and fruit production per flower ranged from neutral to positive depending on year of the experiment. 4. As expected if competition for host resources limits reproductive success more than mate availability in larger infrapopulations, the greater pollen receipt to females in large infrapopulations did not generally translate into increased mistletoe fruit production. Relationships between mistletoe fruit production per flower and infrapopulation size ranged from negative to neutral. 5. Both pollen receipt and pollinator visitation increased with infrapopulation size, indicating that larger populations can be more attractive to pollen vectors independent of mate availability. However, we found no relationship between infrapopulation size and fruit removal by dispersers and, thus, no evidence that attraction of seed dispersal vectors increases with infrapopulation size. 6. Synthesis: These results highlight the interactive roles of within-host processes (resource competition, mate availability, and vector attraction) in determining the fitness of biotically-transmitted parasite individuals.

<p>This dataset contains 15 leaf traits and the relative light availability from 400 trees at sub-individual level. Leaf samples were collected in August and September 2017 in the BEF-China main experiment (site A) in different sampling heights within the individuals. Samples were taken in 66 plots across all diversity levels of the experimental site. Leaf traits were analysed using near-infrared spectroscopy. Available leaf traits are LDMC, SLA, leaf N, leaf C, CN ratio, leaf Mg, leaf Ca, leaf K, leaf P, leaf S, cellulose, lignin, phenolics and tannin. Additionally, light data is available for each height level.</p>
Tree seedling functional traits mediate plant-soil feedback survival responses across a gradient of light availability
<p>Though not often examined together, both plant-soil feedbacks (PSFs) and functional traits have important influences on plant community dynamics and could interact. For example, seedling functional traits could impact seedling survivorship responses to soils cultured by conspecific versus heterospecific adults. Furthermore, levels of functional traits could vary with soil culturing source. In addition, these relationships might shift with light availability, which can affect trait values, microbe abundance, and whether mycorrhizal colonization is mutualistic or parasitic to seedlings.</p> <p>To determine the extent to which functional traits mediate PSFs via seedling survival, we conducted a field experiment. We planted seedlings of four temperate tree species across a gradient of light availability and into soil cores collected beneath conspecific (sterilized and live) and heterospecific adults. We monitored seedling survival twice per week over one growing season, and we randomly selected subsets of seedlings to measure mycorrhizal colonization and phenolics, lignin, and NSC levels at three weeks.</p> <p>Though evidence for PSFs was limited, <em>Acer saccharum</em> seedlings exhibited positive PSFs (i.e., higher survival in conspecific than heterospecific soils). In addition, soil microbes had a negative effect on <em>A. saccharum</em> and <em>Prunus serotina</em> seedling survival, with reduced survival in live versus sterilized conspecific soil. In general, we found higher trait values (measured amounts of a given trait) in conspecific than heterospecific soils and higher light availability. Additionally, <em>A. saccharum</em> survival increased with higher levels of phenolics, which were higher in conspecific soils and high light.<em> Quercus alba</em> survival decreased with higher AMF colonization.</p> <p>We demonstrate that functional trait values in seedlings as young as three weeks vary in response to soil source and light availability. Moreover, seedling survivorship was associated with trait values for two species, despite both drought and heavy rainfall during the growing season that may have obscured survivorship-trait relationships. These results suggest that seedling traits could have an important role in mediating the effects of local soil source and light levels on seedling survivorship and thus plant traits could have an important role in PSFs.</p>
Floral resource availability and honeybee flower visitations in Oslo, Norway
<p>Urban green infrastructure can provide important habitats for pollinators and support urban ecosystem services. Therefore, these areas must be managed to maximize biodiversity and density of pollinating insects. We used DNA metabarcoding to study honeybee pollen resource use over time and space in the city of Oslo, Norway, and to assess the role of green infrastructure as a resource for pollinators and the services they generate. Urban honeybees used diverse pollen resources throughout their active season. There was considerable seasonal turnover in pollen resource use that reflected flowering phenology. Non-native plants (including invasive species) were an important resource early in the season but were replaced by native plants later in the season. Hive location was not strongly correlated with resource use, likely indicating effective long-distance foraging in the fragmented urban landscape. However, flower visitation rates and floral resource density in public urban green spaces were coupled with pollen use. Honeybees collected pollen from a small number of preferred species but also visited other species, likely for nectar. To preserve pollinator services, urban planning should consider flower resource management, with particular focus on planting native species that can act as early season resources for bees. Public campaigns and other incentive mechanisms to promote the cultivation of native plants that are resources for pollinators and the protection of urban semi-natural habitats have the potential to enhance the value of green infrastructure to support urban pollinators and pollination services.</p>

Soil toxicity and species dominance rather than nutrient availability drive plant species richness in swamp forests of Central Europe
<p><strong>Aim: </strong>A resource-based conceptual model of plant diversity (RBCM) assumes direct relationships between resource supply and the diversity of a local plant assembly. However, the RBCM largely ignores variation imposed by soil toxicity due to climatic effects. Both soil-limiting resources and soil toxicity vary along climatic gradients but their net and interactive effects on plant species diversity remain unknown. We asked how climatic gradients shape resource availability, soil toxicity and dominance of herb-layer graminoids, and how these predictors control local species diversity of herbs and bryophytes.</p> <p><strong>Location: </strong>Swamp forests, Central Europe</p> <p><strong>Taxon: </strong>Vascular plants, bryophytes</p> <p><strong>Methods: </strong>Alpha taxonomic diversity of vascular plants and bryophytes was counted for 101 vegetation plots sampled in temperate swamp forests distributed along an 800-km geographical gradient across the Continental, Alpine and Pannonian biogeographical regions. Path analysis (structural equation modelling) was used to quantify the direct and indirect effects of climatic variables (potential evapotranspiration; PET), limiting resources (soil N/P, Ca, C/N, proxies for light and water availability), and soil toxicity (Mn) on graminoid dominance and community diversity.</p> <p><strong>Results: </strong>PET negatively influenced species richness of both groups analysed either directly or indirectly through its positive effect on the cover of graminoid species. Alpha diversity of herbs was additionally reduced by soil toxicity (Mn). Limiting resources correlated either with species dominance (canopy shading, soil Ca) or with PET (soil N/P ratio), but they did not control species richness pattern.</p> <p><strong>Main Conclusions: </strong>Climate, soil toxicity and species dominance determined alpha diversity instead of the expected importance of soil limiting resources. These results are key to advancing the theoretical framework of the RBCM. Increased soil toxicity (Mn) in well-watered regions favours the dominance of plant competitors at the expense of less tolerant species. This implies a potential threat to wetland diversity under ongoing climate change.</p>
Data from: A test of the seasonal availability of water hypothesis in a C3/C4 mixed grassland
<p>Understanding how cool-season C<sub>3</sub> and warm-season C<sub>4</sub> grasses will respond to climate change is critical for predicting future grassland functioning. With warming, C<sub>4</sub> grasses are expected to increase relative to C<sub>3</sub> grasses. But, alterations in the seasonal availability of water may also influence C<sub>3</sub>/C<sub>4</sub> dynamics because of their distinct seasons of growth. To better understand how shifts in the seasonal availability of water can affect ecosystem function in a northern mixed grass prairie in southeastern Wyoming, we reduced early season rainfall (April – June 2021) using rainout shelters and added the amount of excluded precipitation during the latter half of the growing season (July-September), effectively shifting spring rainfall to summer rainfall. As expected, this shift in precipitation seasonality influenced patterns of soil water availability, leading to increased soil respiration in the summer months and sustained canopy greenness throughout the growing season. Despite these responses, there were no significant differences in C<sub>3</sub> aboveground net primary production (ANPP) between the seasonally shifted treatment (SEAS) and the plots that received ambient (AMB) precipitation. This was likely due to the high levels of spring soil moisture present before rainout shelters were deployed that sustained C<sub>3</sub> grass growth. However, in plots with high C<sub>4</sub> grass cover, C<sub>4</sub> ANPP increased significantly in response to increased summer rainfall. Overall, we provide the first experimental evidence that shifts in the seasonality of precipitation, with no change in temperature, will differentially impact C<sub>3</sub> vs. C<sub>4</sub> species, altering the dynamics of carbon cycling and canopy albedo in this extensive semi-arid grassland.</p>
Human access constrains optimal foraging and habitat availability in an avian generalist
<p>Animals balance costs of anti-predator behaviors with resource acquisition to minimize hunting and other mortality risks and maximize their physiological condition. This inherent trade-off between forage abundance and quality, and mortality risk is intensified in human-dominated landscapes because fragmentation, habitat loss, and degradation of natural vegetation communities is often coupled with artificially-enhanced vegetation (i.e., food plots) creating high-risk high-reward resource selection decisions. Our goal was to evaluate autumn–winter resource selection trade-offs for an intensively hunted avian generalist. We hypothesized human access was a reliable cue for hunting predation risk and thus predicted resource selection patterns would be spatiotemporally dependent upon levels of access and their perceived risk. Specifically, we evaluated resource selection of local-scale flights between diel periods of 426 mallards (<em>Anas</em> <em>platyrhynchos</em>) relative to wetland type, forage quality, and differing levels of human access across hunting and non-hunting seasons. Mallards selected areas that prohibited human access and generally avoided areas that allowed access diurnally, especially during hunting season. Mallards compensated by selecting for high-energy and greater quality foraging patches on allowable human access areas nocturnally when they were devoid of hunters. Post-season selection across human access gradients did not return to pre-hunting levels immediately, perhaps suggesting a delayed response to reacclimate to non-hunted activities and thus agreeing with the assessment mismatch hypothesis. Last, wetland availability and human access constrained selection for optimal natural forage quality (i.e., seed biomass and forage productivity) diurnally during pre-season and hunting season, respectively; however, mallards were freed from these constraints nocturnally during hunting season and during post-season. Our results suggest risk-avoidance of human accessible (i.e., hunted) areas is a primary driver of resource selection behaviors by mallards and could be a local to landscape-level process influencing distributions, instead of forage abundance and quality, which has long-been assumed by waterfowl conservation planners in North America. Broadly, even an avian generalist, well-adapted to anthropogenic landscapes, avoids areas where hunting and human access is allowed. Future conservation planning and implementation must consider management for recreational access (i.e., people) equally important as foraging habitat management for wintering waterfowl.</p>
Fungal symbiont diversity drives growth of Holcus lanatus depending on soil nutrient availability
<ol> <li>Arbuscular mycorrhizal (AM) fungi frequently colonise plant roots and can affect plant morphology and physiology through their contribution to plant nutrition. However, the functional role of AM fungi in the presence of other microbial symbionts, including widespread Mucoromycotina 'fine root endophytes' (MFRE) fungi, remains largely unknown.</li> <li>While both AM fungi and MFRE transfer nutrients, including nitrogen, from inorganic and organic sources to host plants, their combined effects on co-colonised plants have only been investigated in liverworts. Here, we compare the morphology and physiology of the grass <em>Holcus lanatus</em> grown with an AM fungal community versus a more diverse symbiotic fungal community containing both AM fungi and MFRE. </li> <li> <em>Holcus lanatus</em> plants were grown in the presence of either a diverse MFRE+AM fungi soil inoculum or a multi-species AM fungal inoculum. Plant traits associated with growth were quantified, along with fungal transfer of <sup>15</sup>N tracer to plants from a variety of sources (ammonium chloride, alanine, glycine, algal necromass). </li> <li> <em>Holcus lanatus</em> grown with the AM fungal community had greater root and shoot growth during early development and prior to the addition of <sup>15</sup>N-labelled sources, compared to plants grown with the more diverse symbiotic fungal community. When nitrogen sources were made available to the fungal symbionts in the pot microcosms, plants growing with the MFRE+AM fungi soil inoculum had a faster growth rate than plants growing with the AM fungal community. At harvest, <em>H. lanatus</em> grown with the AM fungal community had a larger biomass and there were no differences in <sup>15</sup>N tracer assimilation in plants across the two fungal community treatments.</li> <li>Our results demonstrate that the diversity of fungal inocula in conjunction with soil nutrient availability determines the benefits derived by plants from diverse fungal symbionts. Our research contributes to understanding host plant outcomes in diverse multi-symbiont scenarios.</li> </ol>
Data for: Spatial prey availability and pulsed reproductive tactics: encounter risk in a canid-ungulate system
<ol> <li>Predation risk is a function of spatiotemporal overlap between predator and prey, as well as behavioral responses during encounters. Dynamic factors (e.g., group size, prey availability, and animal movement or state) affect risk, but rarely are integrated in risk assessments. Our work targets a system where predation risk is fundamentally linked to temporal patterns in prey abundance and behavior. For neonatal ungulate prey, risk is defined within a short temporal window during which the pulse in parturition, increasing movement capacity with age, and anti-predation tactics have the potential to mediate risk.</li> <li>In our coyote – mule deer (<em>Canis</em> <em>latrans</em> – <em>Odocoileus</em> <em>hemionus</em>) system, leveraging GPS data collected from both predator and prey, we tested expectations of the shared enemy and reproductive risk hypotheses. We asked two questions regarding risk: (A) how do primary and alternative prey habitat, predator and prey activity, and reproductive tactics (e.g., birth synchrony, maternal defense) influence vulnerability of a neonate encountering a predator? (B) How do the same factors affect behavior by predators relative to time before and after an encounter?</li> <li>Despite increased selection for mule deer and intensified search behavior by coyotes during the peak in mule deer parturition, mule deer were afforded protection from predation via predator swamping, experiencing reduced per-capita encounter risk when most neonates were born. Mule deer occupying rabbit habitat (<em>Sylvilagus</em> spp.; coyote's primary prey) experienced the greatest risk of encounter but the availability of rabbit habitat did not affect predator behavior during encounters. Encounter risk increased in areas with greater availability of mule deer habitat, coyotes shifted their behavior relative to deer habitat, and the pulse in mule deer parturition and movement of neonatal deer during encounters elicited increased speed and tortuosity by coyotes.</li> <li>In addition to the spatial distribution of prey, temporal patterns in prey availability, and animal behavioral state were fundamental in defining risk. Our work reveals the nuanced consequences of pulsed availability on predation risk for alternative prey, whereby responses by predators to sudden resource availability, the lasting effects of diversionary prey, and inherent antipredation tactics ultimately dictate risk.</li> </ol>
Nitrogen and phosphorus availability alter tree-grass competition intensity in savannas
<p>Plant essential macronutrients like nitrogen (N) and phosphorus (P) can limit savanna tree growth and are important determinants of savanna vegetation dynamics, along with rainfall, fire, and herbivory. How nitrogen and phosphorus shape tree-grass competition and their coexistence remain unclear, hindering our ability to predict how savannas may respond to altered nutrient cycling.</p> <p>Here, we evaluate (1) if trees and grasses respond differently to N vs. P availability, or (2) if grasses are more competitive in low nutrient environments while trees are more competitive in high nutrient environments. To do this, we grew saplings of 6 tree and 1 grass species from Kruger National Park, South Africa, for 16 weeks under fully factorial nutrient and competition treatments (with/without competitors, low/high rate of N supply, and low/high rate of P supply) under a watering regime designed to mimic wet season rainfall in a mesic savanna.</p> <p>Trees and grasses foraged most aggressively for nitrogen and allocated biomass differently depending on nitrogen availability. Overall, tree growth decreased in competition with grass, even in high nutrient environments where they grew faster. Grasses were always better belowground competitors, utilizing aggressive nutrient foraging strategies, including high root phosphatase activity in response to nitrogen and large root biomass allocation.</p> <p><em>Synthesis:</em> In low nutrient environments (e.g., on nutrient-poor sandy soils), nutrients may limit tree growth. Nutrient rich environments enable tree growth, but grasses continue to compete effectively with trees. Understanding what this means for ecosystem responses to nutrient availability is not trivial, especially in the context of fire and herbivory. However, it is clear that soil nutrients likely affect tree and grass growth and competition in savannas, which suggests that future changes in nutrient cycling, such as N deposition, may have important effects on savanna vegetation.</p>
Data from: In the social amoeba Dictyostelium discoideum, shortened stalks may limit obligate cheater success even when exploitable partners are available
<p>Cooperation is widespread across life, but its existence can be threatened by exploitation. The rise of obligate social cheaters that are incapable of contributing to a necessary cooperative function can lead to the loss of that function. In the social amoeba <em>Dictyostelium discoideum</em>, obligate social cheaters cannot form dead stalk cells and in chimeras instead form living spore cells. This gives them a competitive advantage within chimeras. However, obligate cheaters of this kind have thusfar not been found in nature, probably because they are often enough in clonal populations that they need to retain the ability to produce stalks. In this study we discovered an additional cost to obligate cheaters. Even when there are wild-type cells to parasitize, the chimeric fruiting bodies that result have shorter stalks and these are disadvantaged in spore dispersal. The inability of obligate cheaters to form fruiting bodies when they are on their own combined with the lower functionality of fruiting bodies when they are not represent limits on obligate social cheating as a strategy<em>.</em></p>
Caffeine citrate status, availability and practice across Nigeria, Ethiopia, Kenya, South Africa and five States in India
<p>Apnea of prematurity (AOP) is a common complication among preterm infants (<37 weeks gestation), globally. However, access to caffeine citrate (CC) that is a proven safe and effective treatment in high income countries is largely unavailable in low-and-middle income countries, where most preterm infants are born. Therefore, the overall aim of this study was to describe the demand, policies, and supply factors affecting the availability and clinical use of CC in LMICs.</p> <p>A mixed methods approach was used to collect data from diverse settings in LMICs including Ethiopia, Kenya, Nigeria, South Africa, and India. Qualitative semi-structured interviews and focus group discussions were conducted with different health care providers, policymakers, and stakeholders from industry. Additional data was collected using standard questionnaires. A thematic framework approach was used to analyze the qualitative data and descriptive statistics were used to summarize the quantitative data. The findings indicate that there is variation in in-country policies on the use of CC in the prevention and treatment of AOP and its availability across the LMICs. As a result, the knowledge and experience of using CC also varied with clinicians on Ethiopia having no experience of using it while those in India have greater knowledge and experience of using it. The in turn influenced the demand and our findings show that only 29% of eligible preterm infants are receiving CC in these countries.</p> <p>There is an urgent need to address the multilevel barriers to accessing CC for management of AOP in Africa. These include cost, lack of national policies and therefore lack of demand stemming from its clinical equivalency with aminophylline. Practical ways to reduce the cost of CC in LMICs could potentially increase its availability and use.</p>

The effects of microplastics on crop variation depend on polymer types and their interactions with soil nutrient availability and weed competition
<p>Microplastics pollution of agricultural soil is a global environmental concern because of its potential risk to food security and human health. Although many studies have tested the direct effects of microplastics on growth of <em>Eruca sativa</em> Mill., little is known about whether these effects are regulated by fertilization and weed competition in field management practices.</p> <p>Here, we performed a greenhouse experiment growing <em>E. sativa</em> as target species in a three-factorial design with two levels of fertilization (low versus. high), two levels of weed competition treatments (weed competition versus no weed competition) and five levels of microplastic treatments (no microplastics, Polybutylene adipateco-terephthalate [PBAT], Polybutylene succinate [PBS], Polycaprolactone [PCL] or Polypropylene [PP]).</p> <p>Compared to the soil without microplastics, PBS and PCL reduced aboveground biomass and leaf number of the <em>E. sativa</em>. PBS also resulted in increased root allocation and thicker roots in <em>E. sativa</em>. In addition, fertilization significantly mitigated the negative effects of PBS and PCL on aboveground biomass of <em>E. sativa</em>, but weed competition significantly promoted these effects. Although fertilization alleviated the negative effect of PBS on aboveground biomass, such alleviation became weaker under weed competition than when <em>E. sativa</em> grew alone.</p> <p>The results indicate that the effects of specific polymer types on <em>E. sativa</em> growth could be regulated by fertilization, weed management, and even their interactions. Therefore, reasonable on-farm management practices may help in mitigating the negative effects of microplastics pollution on <em>E. sativa</em> growth in agricultural fields.</p>
