Laboratory study on microplastic fiber size and concentration effects on leopard frog (Lithobates pipiens) tadpole survival, development, behavior, and parasite susceptibility
This dataset contains comprehensive raw data from a completed laboratory experiment conducted from May 24 to June 30, 2021 (with additional analysis performed in 2025), investigating the effects of polyester microplastic (MP) fiber exposure on northern leopard frog (Lithobates pipiens) tadpoles and their interactions with echinostome trematodes (Echinostoma sp.). Tadpole egg masses were collected from a wetland in Indiana, USA, and ramshorn snails (Helisoma trivolvis), serving as trematode hosts, were collected from Tioga County, New York, USA. The experiment was conducted under controlled laboratory conditions using a static-renewal design, exposing tadpoles to short (~0.24 mm) or long (~1.50 mm) polyester MP fibers at concentrations of 0, 10, or 40 µg L⁻¹ for 32 days, followed by controlled exposure to echinostome cercariae. The dataset includes measurements of tadpole mortality, developmental traits (mass, snout-to-vent length, Gosner stage), behavioral activity (number of moving pre- and post-parasite exposure), MP fiber ingestion, and susceptibility to trematode infection (metacercarial cyst counts in kidneys). These data provide a resource for studying the ecological and toxicological impacts of microplastics on amphibian health, and host-parasite dynamics in freshwater ecosystems, making the dataset suitable for researchers in ecotoxicology, and disease ecology. The dataset is complete, with no ongoing data collection, and is designed to support analyses of microplastic-mediated effects on aquatic organisms.

Food and social cues modulate reproductive development but not migratory behavior in a nomadic songbird, the Pine Siskin (Pinus spinus)
<p>Many animals rely on photoperiodic and non-photoperiodic environmental cues to gather information and appropriately time life history stages across the annual cycle, such as reproduction, molt, and migration. Here, we experimentally demonstrate that the reproductive physiology, but not migratory behavior, of captive Pine Siskins responds to both food and social cues during the spring migratory-breeding period. Pine Siskins are a nomadic finch with a highly flexible breeding schedule and, in the spring, free-living Pine Siskins can wander large geographic areas and opportunistically breed. To understand the importance of non-photoperiodic cues to the migratory-breeding transition, we maintained individually housed birds on either a standard or enriched diet in the presence of group-housed heterospecifics or conspecifics experiencing either the standard or enriched diet type. We measured body condition and reproductive development of all Pine Siskins and, among individually housed Pine Siskins, quantified nocturnal migratory restlessness. In group-housed birds, the enriched diet caused increases in body condition and, among females, promoted reproductive development. Among individually housed birds, female reproductive development differed between treatment groups whereas male reproductive development did not. Specifically, individually housed females showed greater reproductive development when presented with conspecifics compared to heterospecifics. The highest rate of female reproductive development, however, was observed amongst individually housed females provided the enriched diet and maintained with group-housed conspecifics on an enriched diet. Changes in nocturnal migratory restlessness did not vary by treatment group or sex. By manipulating both the physical and social environment, this study demonstrates how multiple environmental cues can affect the timing of transitions between life history stages with differential responses between sexes and between migratory and reproductive systems.</p>

Urban heat island conditions experienced by the Western black widow spider (Latrodectus hesperus): extreme heat slows development but results in behavioral accommodations
Herein lies data on urban h eat island conditions for black widow spiders across the CAP study area. It also includes data on the development speed and behavioral responses of spiders reared in the lab at these UHI temperatures. The urban heat island (UHI) effect describes the capture of heat by built structures (e.g. asphalt), resulting in elevated urban temperatures. The UHI is a well-studied phenomenon, but only a handful of studies have investigated trait-based shifts resulting from the UHI, and even fewer have attempted to quantify the magnitude of the UHI experienced at the microclimate scale. Here, using a common urban exploiter, the Western black widow spider (Latrodectus hesperus), we show that the UHI experienced by spiders in July in their urban Phoenix, AZ refuges is 6 degrees C hotter (33 degrees C) than conditions in the refuges of spiders from Sonoran Desert habitat outside of Phoenix-area development (27 degrees C). We then use this field microclimate UHI estimate to compare the development speed, mass gain and mortality of replicate siblings from 36 urban lineages reared at temperatures that reflect urban and desert habitats. We show that extreme heat is slowing the growth of spiderlings and increasing mortality. In contrast, we show that development of male spiders to their penultimate moult is accelerated by 2 weeks. Lastly, in terms of behavioral shifts, UHI temperatures caused late-stage juvenile male spiders to heighten their foraging voracity and late-stage juvenile female spiders to curtail their web-building behavior.
Data from: Residential development alters behavior, movement, and energetics in an apex predator, the puma
Human development strongly influences large carnivore survival and persistence globally. Behavior changes are often the first measureable responses to human disturbances, and can have ramifications on animal populations and ecological communities. We investigated how a large carnivore responds to anthropogenic disturbances by measuring activity, movement behavior, and energetics in pumas along a housing density gradient. We used log-linear analyses to examine how habitat, time of day, and proximity to housing influenced the activity patterns of both male and female pumas in the Santa Cruz Mountains. We used spatial GPS location data in combination with Overall Dynamic Body Acceleration measurements recorded by onboard accelerometers to quantify how development density affected the average distances traveled and energy expended by pumas. Pumas responded to development differently depending on the time of day; at night, they were generally more active and moved further when they were in developed areas, but these relationships were not consistent during the day. Higher nighttime activity in developed areas increased daily caloric expenditure by 10.1% for females and 11.6% for males, resulting in increases of 3.4 and 4.0 deer prey required annually by females and males respectively. Our results support that pumas have higher energetic costs and resource requirements in human-dominated habitats due to human-induced behavioral change. Increased energetic costs for pumas are likely to have ramifications on prey species and exacerbate human-wildlife conflict, especially as exurban growth continues. Future conservation work should consider the consequences of behavioral shifts on animal energetics, individual fitness, and population viability.
Data from: Dimensionality of locomotor behaviors in developing C. elegans
<p>Adult animals display robust locomotion, yet the timeline and mechanisms of how juvenile animals acquire coordinated movements and how these movements evolve during development are not well understood. Recent advances in quantitative behavioral analyses have paved the way for investigating complex natural behaviors like locomotion. In this study, we tracked the swimming and crawling behaviors of the nematode <em>Caenorhabditis elegans</em> from postembryonic development through to adulthood. Our principal component analyses revealed that adult <em>C. elegans </em>swimming is low dimensional, suggesting that a small number of distinct postures, or eigenworms, account for most of the variance in the body shapes that constitute swimming behavior. Additionally, we found that crawling behavior in adult <em>C. elegans</em> is similarly low dimensional, corroborating previous studies. Further, our analysis revealed that swimming and crawling are distinguishable within the eigenworm space. Remarkably, young L1 larvae are capable of producing the postural shapes for swimming and crawling seen in adults, despite frequent instances of uncoordinated body movements. In contrast, late L1 larvae exhibit robust coordination of locomotion, while many neurons crucial for adult locomotion are still under development. In conclusion, this study establishes a comprehensive quantitative behavioral framework for understanding the neural basis of locomotor development, including distinct gaits such as swimming and crawling in <em>C. elegans</em>.</p>
Algal growth, bumblebee colony and individual development, bee behavior and yield of oilseed rape under a trophic cascade and extreme weather
<p><span>Trophic cascades in the aquatic environment constitute important mechanisms for improving water quality. However, how the presence or non-presence of these trophic cascades may affect interactions across the aquatic-terrestrial interface remains poorly investigated. Pollinators such as bees may be especially vulnerable to changes in water resource quality induced by trophic cascades. Understanding how aquatic trophic cascades affect bees and pollination becomes even more pressing under ongoing climate change due to increased physiological demands for water under extreme weather events.</span><span>In a novel field experiment combining terrestrial and aquatic mesocosms, we aimed to test how changes in water quality induced by an aquatic trophic cascade </span><span>affected foraging and growth of bumblebee colonies as well as foraging of solitary bees. While we expected fish predation to reduce top-down control of zooplankton on phytoplankton and thereby, indirectly, induce increased growth of toxic cyanobacteria</span><span>, we instead found the trophic cascade to induce the formation of algal surface mats that bumblebees used to access water under a severe heat wave and drought. This access to water was associated with higher bumblebee colony reproductive success, growth and weight compared to control colonies with no trophic cascade induced (and hence no algal surface mats). We also found marginal </span><span>but non-significant</span><span> effects on oilseed rape yield, but surprisingly with higher yields in the control treatment where bumblebees could not access water.</span><span>Our results provide new insights on how aquatic trophic cascades can lead to unpredicted ecological interactions across the aquatic-terrestrial interface facilitated by climate change. Our study highlights the importance of water for the fitness of terrestrial ecosystem service providers under altered environmental conditions.</span></p>

Short-range C-signaling restricts cheating behavior during Myxococcus xanthus development
<p>Starving <em>Myxococcus xanthus</em> bacteria use short-range C-signaling to coordinate building of multicellular mounds with differentiation from rods into spores during fruiting body development. A <em>csgA</em> mutant deficient in C-signaling can cheat on wild type (WT) in mixtures and form spores disproportionately, but our understanding of cheating behavior is incomplete. We report that cheating requires excess WT cells in the initial mixture and occurs during the mound-building phase of development. We subjected mixtures of WT and <em>csgA</em> cells at different ratios to co-development, and used confocal microscopy and image analysis to quantify the arrangement and morphology of cells near the bottom of nascent fruiting bodies (NFBs). At a ratio of one WT to four <em>csgA</em> cells (1:4), NFBs failed to form. At 1:2, broad mounds formed with half the normal cell density and very few spores. At 1:1, NFBs formed normally with a similar number of WT and <em>csgA</em> rods early in development and a similar number of spores later, so C-signaling by WT rescued <em>csgA </em>development efficiently, but the mutant<em> </em>did not cheat. In contrast, at 2:1 and 4:1 excess WT starting ratios, <em>csgA</em> rods were more abundant than expected in early NFBs, indicative of cheating during mound formation. As NFBs matured, <em>csgA</em> and WT eventually formed spores with similar efficiency, although <em>csgA</em> began sporulation earlier and closer to the radial center. Our results reveal restrictions on cheating behavior, which may have selected C-signaling evolutionarily, and may explain the prevalence of short-range signaling in bacterial biofilm and multicellular animal development.</p>
