Fundamental niche narrows through larval stages of a filter-feeding marine invertebrate
<p>Ontogenetic niche theory predicts that resource use should change across complex life histories. To date, studies of ontogenetic shifts in food niches have mainly focused on a few systems (e.g. fish), with less attention on organisms with filter-feeding larval stages (e.g. marine invertebrates). Recent studies suggest that filter-feeding organisms can select specific particles, but our understanding of whether niche theory applies to this group is limited. We characterised the fundamental niche (i.e. feeding proficiency) by examining how niche breadth changes across the larval stages of the filter-feeding marine polychaete <em>Galeolaria</em> <em>caespitosa</em>. Using a no-choice experimental design, we measured feeding rates of trochophore, intermediate-stage and metatrochophore larvae on the prey phytoplankton species: <em>Nannochloropsis</em> <em>oculata</em>, <em>Tisochrysis</em> <em>lutea</em>, <em>Dunaliella</em> <em>tertiolecta</em> and <em>Rhodomonas</em> <em>salina</em>, that vary 10-fold in size, from the smallest to the largest. We formally estimated Levins' niche breadth index to determine the relative proportions of each species in the diet of the three larval stages and also tested how feeding rates vary with algal species and stage. We found that early stages eat all four algal species in roughly equal proportions, but niche breadth narrows during ontogeny, such that metatrochophores are feeding specialists relative to early stages. We also found that feeding rates differed across phytoplankton species—the medium-sized cells (<em>Tisochrysis</em> and <em>Dunaliella</em>) were eaten most, and the smallest species (<em>Nannochloropsis</em>) was eaten the least. Our results demonstrate that ontogenetic niche theory describes changes in fundamental niche in filter feeders—an important next step is to test whether the realized niche (i.e. preference) changes during the larval phase as well.</p>

Data from: Policing is more effective against eggs of non-natal versus natal workers at early colony stages in a bumblebee
<p>Eusocial insect colonies are vulnerable to exploitation by egg-laying workers arising either as natal reproductive workers or as non-natal reproductive 'drifting' workers (intraspecific social parasites). Worker egg-laying is potentially costly to the colony, but queens and workers can counter its costs via egg-eating (queen or worker policing). Bumblebee colonies exhibit egg laying by both natal and non-natal workers: natal workers collectively lay more eggs but do so only after a specific point in the colony cycle, the 'competition point', whereas non-natal workers potentially lay eggs throughout the colony cycle. These features create a special opportunity to investigate whether policing of worker-laid eggs is context-dependent (i.e. depends on worker origin of eggs and/or colony stage). <span>We introduced artificial egg cells containing eggs laid by either natal or non-natal workers into colonies of the bumblebee <em>Bombus terrestris</em> both before and after their competition points, and observed the fate of introduced egg cells and eggs. In both colony stages, the majority of introduced egg cells and eggs were policed, demonstrating that policing was not activated only after the competition point. However, in the pre-competition point stage alone, a smaller proportion of non-natal workers' eggs (15%) remained after 20 h compared to the proportion of natal workers' eggs remaining (24%). More effective policing of non-natal workers' eggs early in the colony cycle potentially represents an adaptive, context-dependent response to the stage in the cycle when all worker-laid eggs are normally unrelated to the natal colony. </span></p>

<p># Artifact Description</p> <p>This dataset includes the inputs, outputs, job submission scripts, and data analysis scripts used to prepare the ECP WarpX Year 7 Milestone 1 report for "Convergence study in 3-D of 15 to 30 consecutive multi-GeV stages." The code versions of WarpX, AMReX, and PICSAR used are stored in the output* file for each run. Furthermore, a 3D visualization of a completed run is included.</p> <p>However, since the used code version included very recent enhancements that will only enter the WarpX mainline (development) branch at a later point in time via pull request, this dataset also contains the WarpX source code that was used for the runs. </p> <p>Features added include:</p> <ul> <li>https://github.com/ECP-WarpX/WarpX/pull/3734</li> </ul> <p>Please see the meta-data for a link to the WarpX mainline repository/archives and documentation of WarpX.</p> <p>Each run directory contains the input and submission scripts, compute-job related output files, a Jupyter notebook for analysis, and an analysis directory. The latter contains a figure comparing the mean beam energy (Lorentz factor), and emittance evolution over the course of the simulation. It also contains the data in CSV format that was used to create the figures. </p> <p># Acknowledgments</p> <p>WarpX is supported by the Exascale Computing Project (17-SC-20-SC), a collaborative effort of two U.S. Department of Energy organizations (Office of Science and the National Nuclear Security Administration) responsible for the planning and preparation of a capable exascale ecosystem, including software, applications, hardware, advanced system engineering, and early testbed platforms, in support of the nation's exascale computing imperative.</p> <p> </p>
Data for: Widespread wood placement and regrading drive lateral connectivity and reworking of the channel and floodplain in a valley bottom reset to stage 0
<p>Valley bottom process reset, or the excavation of high surfaces and fill of incised channels combined with large wood addition, is a new method for creating multi-channel river-wetland corridors (also referred to as Stage 0 valley bottoms). Valley bottom process reset seeks to increase lateral flow and sediment connectivity to retain flow and sediment and kickstart geomorphic processes that may sustain aquatic and riparian habitats. This anthropogenic intervention provides an opportunity to examine relationships among wood-induced hydraulic roughness, valley bottom topography, and geomorphic processes such as overbank flow and sediment transport, avulsion, sediment retention, and pool scour. Here, I present a 6-year case study of a two-phase valley bottom process reset along Deer Creek, OR which indicates that kickstarting processes that reshape the floodplain requires a substantial increase in roughness and hydrologic connectivity. A first phase of construction enhanced hydrologic but not sediment connectivity, largely failing to kickstart avulsion and floodplain reworking even during a likely 2- to 5-year recurrence interval flood. A second, more intensive phase of construction substantially reduced the threshold flow necessary for overbank flow and incision of floodplain reworking, as evidenced by the occurrence of these processes after only a < 2-year recurrence interval flood. During this flood, a spatially distributed wood lattice rearranged into discrete jams that scoured pools, retained sediment, and drove geomorphically effective overbank flows. While valley bottom regrading likely contributed to these geomorphic effects, the spatial correlation between newly incised floodplain channels and areas of wood aggregation indicates a substantial role of wood-induced hydraulic roughness and channel blockage. Wood drove floodplain reworking via two mechanisms: in-channel wood jams backwatered and constructed flow into the floodplain, and small wood jams formed in the floodplain forest further constricted flow through nascent channels to facilitate channel incision.</p>
