CausalOrca: An ORCA-based Diagnostic Dataset for Causally-aware Multi-agent Trajectory Prediction
<p>CausalOrca is a synthetic diagnostic dataset created through controlled simulations. It is designed to provide annotations of ground-truth causal effects and fine-grained agent categories for social interactions in multi-agent scenarios. The dataset is constructed using a modified RVO2 simulator and incorporates the ORCA optimization-based collision avoidance algorithm known for crowd simulation. With full control over scene configurations, the dataset enables the collection of motion behaviors in paired scenes before and after agent removal, generating a large set of counterfactual pairs with annotations of ground-truth causal effects. CausalOrca can serve as a valuable resource for studying and developing causally-aware neural representations of social interactions and trajectory prediction models. Please see the <a href="https://github.com/rebuttal-anonymous/causalorca">GitHub repository</a> for a more detailed description of the dataset, including dataset statistics and documentation on how to use, visualize, and generate the data.</p>

Crowdsourced dataset of firefly trajectories obtained by automated stereo calibration of 360-degree cameras
<p>Advancements in animal tracking techniques, spanning from migrating mammals to swarming insects, have resulted in remarkable progress in the fields of behavioral ecology and conservation science. Recently, we have devised a method for tracking luminous fireflies in their natural habitat using stereoscopic pairs of 360-degree cameras. This method offers affordability, versatility, and ease of setup; however, the process of camera calibration has remained tedious and time-consuming. Now, we have introduced an enhanced algorithm that achieves spatial and temporal stereo calibration directly from the data, eliminating the need for manual procedures both in the field and during video processing. The algorithm relies on cross-correlation of flashing patterns and numerical estimation of camera pose. Utilizing this improved protocol and processing software, we have compiled an extensive dataset comprising over 100 reconstructed firefly swarms of various species. This data was gathered throughout the United States by numerous contributors following a straightforward protocol. The dataset holds significant potential for advancing our comprehension of firefly collective behavior, facilitating population monitoring, and expanding citizen science initiatives.</p>

FESOM-REcoM model data: Lagrangian particle trajectories
<p>This data set includes the results of Lagrangian particle tracking experiments with FESOM1.4-REcoM2. Particles were seeded at 596 positions near the Filchner Ice Shelf front at 78°S between Berkner Island and Coats Land and tracked forwards and backwards using daily mean model output. Particles were seeded every 10th day in 1990 and 1991 (historical, forward), 2009 and 2008 (historical, backward), 2080 and 2081 (future/SSP5-8.5 scenario, forward), and 2099 and 2098 (future/SSP5-8.5 scenario, backward). Particles were tracked outside of ice-shelf cavities for 20 (19) years or until the the particle left the domain of interest in the north (62°S), west (65°W), or east (2°E). </p> <p>The following information for each particle is stored twice a day: longitude (blon in files), latitude (blat), time (bday and time), depth (bdepth), temperature (btemp), salinity (bsalt), density (bsigma0; potential density anomaly referenced to 0dbar) dissolved inorganic carbon (bdic), and total carbon (btotc).</p> <p>Each *tar.gz archive contains one experiment, i.e., all trajectories for e.g., forward/1990-2009 (seeding days 1,11,...,361 in 1990). For each seeding day, there are 12 *nc files, which together constitute the 596 particles seeded on a given day.</p> <p> </p> <p><strong>Naming convention / *tar.gz files: </strong></p> <p>Nissen2023_FESOM1.4_REcoM2_Trajectories_FT_<em>EXPERIMENT</em>_<em>START_END_YEAR</em>.tar.gz</p> <p><em>EXPERIMENT</em>: bw (backward) or fw (forward)</p> <p><em>START_END_YEAR</em>: 2009_1990, 2008_1990, 2098_2080, or 2099_2080 for backward experiments; 1990_2009, 1990_2008, 2080_2099, or 2081_2099 for forward experiments</p> <p>(EXAMPLE: Nissen2023_FESOM1.4_REcoM2_Trajectories_FT_fw_1990_2009.tar.gz)</p> <p><strong>Naming convention / *nc files: </strong></p> <p>drifter_start_Filchner_ice_shelf_day<em>SEEDING_DAY</em>_<em>START_END_YEAR</em>_<em>NUM_FILE</em>_reduced.nc</p> <p><em>SEEDING_DAY: </em>1, 11, ..., 361</p> <p><em>START_END_YEAR: </em>same as above</p> <p><em>NUM_FILE: </em>1, ..., 12</p> <p>(EXAMPLE: drifter_start_Filchner_ice_shelf_day1_1990_2009_1_reduced.nc)</p> <p> </p> <p><strong>NOTE:</strong> The following files are duplicates and also contained in the larger *tar archives described above (disregard them if all tar archives starting with "Nissen2023_FESOM1.4_REcoM2_Trajectories_FT_" have been downloaded):</p> <p>Nissen2023_FESOM1.4_REcoM2_LagrangianExperiments_FT_fw_day91_1991_2009.tar.gz</p> <p>Nissen2023_FESOM1.4_REcoM2_LagrangianExperiments_FT_fw_day91_2080_2099.tar.gz</p> <p> </p> <p><strong>The Lagrangian particle trajectories have been analyzed here:</strong> </p> <p>Nissen, C., Timmermann, R., van Caspel, M., and Wekerle, C.: Altered Weddell Sea warm- and dense-water pathways in response to 21st-century climate change, Ocean Sci., 20, 85–101, <a href="https://doi.org/10.5194/os-20-85-2024">https://doi.org/10.5194/os-20-85-2024</a>, 2024</p> <p><strong>The Eulerian fields underlying the Lagrangian experiments are described in more detail here: </strong></p> <p>Nissen, C., Timmermann, R., Hoppema, M. <em>et al.</em> Abruptly attenuated carbon sequestration with Weddell Sea dense waters by 2100. <em>Nat Commun</em> <strong>13</strong>, 3402 (2022). <a href="https://doi.org/10.1038/s41467-022-30671-3">https://doi.org/10.1038/s41467-022-30671-3</a> </p> <p>Nissen, C., R.

Data from: Beaks promote rapid morphological diversification along distinct evolutionary trajectories in labrid fishes (Eupercaria: Labridae)
<p>The upper and lower jaws of some wrasses (Eupercaria: Labridae) possess teeth that have been coalesced into a strong durable beak that they use to graze on hard coral skeletons, hard-shelled prey, and algae, allowing many of these species to function as important ecosystem engineers in their respective marine habitats. While the ecological impact of the beak is well-understood, questions remain about its evolutionary history and the effects of this innovation on the downstream patterns of morphological evolution. Here we analyze 3D cranial shape data in a phylogenetic comparative framework and use paleoclimate modeling to reconstruct the evolution of the labrid beak across 205 species. We find that wrasses evolved beaks three times independently, once within odacines, and twice within parrotfishes in the Pacific and Atlantic Oceans. We find an increase in the rate of shape evolution in the Scarus+Chlorurus+Hipposcarus (SCH) clade of parrotfishes likely driven by the evolution of the intramandibular joint. Paleoclimate modeling shows that the SCH clade of parrotfishes rapidly morphologically diversified during the middle Miocene. We hypothesize that possession of a beak in the SCH clade coupled with favorable environmental conditions allowed these species to rapidly morphologically diversify.</p>

Fluvial geomorphic evolution and stream fish community trajectories in the Bayou Pierre, Mississippi
<p>Changing environments place stresses on ecosystems, and are contributing to widespread losses of biodiversity and ecosystem function. Comparisons of historical and contemporary data offer considerable utility in understanding how ecosystems respond to, adapt to, or recover from changing environments. Stream fishes offer a particularly interesting study system for this topic, as streams are naturally dynamic environments and human needs have placed increasing pressure on aquatic systems. The effects of fine sediments on stream fishes and aquatic ecosystems more broadly have been well studied. Yet studies from fluvial geomorphology have resulted in models of watershed morphological evolution which encompass far broader processes and changes to aquatic systems. Our dataset integrates a fluvial geomorphic approach to characterize stream channel and habitat evolution over a four decade period in the Bayou Pierre, Mississippi, an ecological approach to study related change in stream fish communities in the same watershed, and analyses linking the two. Fluvial geomorphic processes were characterized both from remote sensing data sources for historic and contemporary time periods, and local fish habitat data for contemporary time periods. Historical fish community data were extracted from museum records, and contemporary fish community data were collected via sampling for fishes at the same localities as historic efforts using similar methods.</p>
