Individual flowering phenology shapes plant-pollinator interactions across ecological scales affecting plant reproduction
<p>1. The balance of pollination competition and facilitation amongst co-flowering plants and abiotic resource availability can modify plant species and individual reproduction. Floral resource succession and spatial heterogeneity modulate plant-pollinator interactions across ecological scales (individual plant, local assemblage, interaction network of agroecological infrastructure across the farm). Intraspecific variation in flowering phenology can modulate the precise level of spatio-temporal heterogeneity in floral resources, pollen donor density and pollinator interactions that a plant individual is exposed to, thereby affecting reproduction.</p> <p>2. We tested how abiotic resources and multi-scale plant-pollinator interactions affected individual plant seed set, modulated by intraspecific variation in flowering phenology and spatio-temporal floral heterogeneity arising from agroecological infrastructure. We transplanted two focal insect-pollinated plant species (<em>Cyanus</em> <em>segetum</em> and <em>Centaurea</em> <em>jacea</em>, n = 288) into agroecological infrastructure (10 sown wildflower, 6 legume-grass strips) across a farm-scale experiment (125 ha).</p> <p>3. We applied an individual-based phenologically explicit approach to match precisely the flowering period of plant individuals to the concomitant level of spatio-temporal heterogeneity in plant-pollinator interactions, potential pollen donors, floral resources and abiotic conditions (temperature, water, nitrogen).</p> <p>4. Individual plant attractiveness, assemblage floral density and conspecific pollen donor density (<em>C</em>. <em>jacea</em>) improved seed set. Network linkage density increased focal species' seed set and modified the effect of local assemblage richness and abundance on <em>C</em>. <em>segetum</em>. Mutual dependence on pollinators in networks increased <em>C</em>. <em>segetum</em> seed set, while <em>C</em>. <em>jacea</em> seed set was greatest where both specialization on pollinators and mutual dependence was high. Abiotic conditions were of little or no importance to seed set.</p> <p>5. Intra- and interspecific plant-pollinator interactions respond to spatio-temporal heterogeneity arising from agroecological management affecting wild plant species reproduction. The interplay of pollinator interactions within and between ecological scales affecting seed set implies a co-occurrence of pollinator-mediated facilitative and competitive interactions among plant species and individuals. </p>

A chromosome-scale reference genome assembly of the great sand eel, Hyperoplus lanceolatus
<p><span>Despite increasing sequencing efforts, numerous fish families still lack a reference genome, which complicates genetic research. One such understudied family is the sand lances (Ammodytidae, literally: 'sand burrower'), a globally distributed clade of over 30 fish species that tend to avoid tidal currents by burrowing into the sand. Here, we present the first annotated chromosome-level genome assembly of the great sand eel (<em>Hyperoplus</em> <em>lanceolatus</em>). The genome assembly was generated using Oxford Nanopore Technologies long sequencing reads and Illumina short reads for polishing. The final assembly has a total length of 808.5 Mbp, of which 97.1% were anchored into 24 chromosome-scale scaffolds using proximity-ligation scaffolding. The assembly is highly contiguous with a scaffold and contig N50 of 33.7 Mbp and 31.3 Mbp, respectively, and has a BUSCO completeness score of 96.9%. The presented genome assembly is a valuable resource for future studies of sand lances, as they are of great ecological and commercial importance and may also contribute to studies aiming to resolve the suprafamiliar taxonomy of bony fishes.</span></p>
Reduced precipitation lessens the scaling of growth to plant N in mesic grasslands
<p>Grassland production is sensitive to both precipitation and plant N accumulation and utilization, such that change in one variable influences grassland response to the second variable. We investigated effects of interannual variation in precipiation on the response of 'community'-scale values of relative growth rate (RGR) to two multiplicative components of RGR, nitrogen productivity (NP; rate of change in biomass/plant N), an index of N utilization efficiency, and plant N concentration ([N]), in two grassslands in Texas, USA. Grasslands included a planted mixture of perennial grass and forb species and a monoculture of the perennial C4 grass Panicum vigatum that was invaded by multiple plant species. RGR and its N components were measured at the spatial scale of 7-m diameter circular patches near the spring peak in mixture biomss during each of 5 years. We found that RGR varied substantially among patches and years and between the planted mixture and monoculture. RGR variation was strongly correlated with variation in NP. Precipitation during the 3 months prior to RGR measurement mediated that RGR response to NP by altering the correlation between NP and [N] in both grasslands. Reduced precipitation led to more negative NP-[N] correlation coefficients, which reduced proportional change in RGR per change in NP by as much as 30% even in the absence of a precipitation effect on means of RGR and NP. Our results highlight an under-appreciated aspect of the pervasive role of precipitation in grassland growth that was mediated via change in the growth benefit derived from plant N.</p>
POSITIVE AGN FEEDBACK AT HUNDREDS OF KPC SCALES IN A PROTOCLUSTER AT Z=1.7
<p>High-z protoclusters are ideal laboratories to investigate the relation between AGN feedback, ICM heating, and galaxy evolution at the peak formation epoch of galaxy clusters.</p> <p>We will present multi-band observations of a z=1.7 protocluster assembling around an FRII radio-galaxy that provide strong insight into the above processes.</p> <p>A deep (0.5 Ms) Chandra look at the system revealed several spots of diffuse X-ray emission, the most prominent of which (bubble A) overlaps with the Eastern radio lobe. We will discuss thermal emission or Inverse Compton scattering of CMB photons (IC-CMB) as viable mechanisms to produce the observed X-ray spots, and present new LOFAR observations suggesting that bubble A is due to IC-CMB. In addition, the expanding plasma in the Western radio-jet and lobe likely shock-heats pockets of gas in the inhomogeneous ambient medium to the ~keV temperature observed in the other X-ray spots.</p> <p>Bubble A is surrounded by the four galaxies with the largest specific star formation rates among all protocluster members. This calls for remarkable, positive AGN feedback produced hundreds of kpc away from the FRII nucleus by the expanding bubble.</p> <p>We will discuss future observations of the system and finally present prospects for future population studies of similar, high-z protoclusters with the Survey and Time-domain Astrophysical Research eXplorer (STAR-X), a Medium Explorer mission selected by NASA for Phase A study.</p> <p> </p>

The Effects of Aerosol on Small-Scale Cloud-Environment Mixing: Implications for Observing Inhomogeneous Mixing
<p>This is the simulation output of the submitted manuscript "The Effects of Aerosol on Small-Scale Cloud-Environment Mixing: Implications for Observing Inhomogeneous Mixing" to the Journal of Geophysical Research: Atmospheres. </p> <p>Abstract: The mixing of clouds with their environment can change the size and number of cloud droplets, two important parameters to understand the role of clouds in the climate system. Because these changes are determined by the way a cloud mixes with its environment, they have been used to characterize the mixing process. Using a highly detailed numerical cloud model coupled with a statistical turbulence model, we show that the adequate consideration of aerosol particles from which cloud droplets grow, can alter the changes of cloud droplets during mixing. This has not been considered in the past. We identify biases that need to be considered when mixing processes are analyzed.</p> <p>The raw data presented here was produced by the aforementioned model only and is completely available.</p>
