Floral spectral reflectance data for: Floral color properties of serpentine seep assemblages depend on community size and species richness

Kathryn LeCroy, Gerardo Arceo-Gómez, Matthew Koski, Nathan Morehouse & Tia-Lynn Ashman
Functional traits, particularly those that impact fitness, can shape the ecological and evolutionary relationships among coexisting species of the same trophic level. Thus, examining these traits and properties of their distributions (underdispersion, overdispersion) within communities can provide insights into key ecological interactions (e.g., competition, facilitation) involved in community assembly. For instance, the distribution of floral colors in a community may reflect pollinator-mediated interactions between sympatric plant species, and the phylogenetic distribution of color can inform...

Audio recordings of Atelpus varius calls from Panama

Justin Kitzes, Samuel Lapp, Corinne Richards-Zawacki, Jamie Voyles, Keely Michelle Rodriguez & Tianhao Wu
Anurans (frogs and toads) are among the most globally threatened taxonomic groups. Successful conservation of anurans will rely on improved data on the status and changes in local populations, particularly for rare and threatened species. Automated sensors, such as acoustic recorders, have the potential to provide such data by massively increasing the spatial and temporal scale of population sampling efforts. We used AudioMoth autonomous recorders to survey for the critically endangered Harlequin toad (Atelopus varius)...

Worn region size of shoe outsole impacts human slips: Testing a mechanistic model

Kurt Beschorner, Vani H. Sundaram, Sarah L. Hemler, Arnab Chanda, Joel M. Haight & Mark S. Redfern
Shoe outsole tread wear has been shown to increase slip risk by reducing the tread’s ability to channel fluid away from the shoe-floor interface. This study establishes a connection between geometric features of the worn region size and slipping. A mechanistic pathway that describes the relationship between the worn region size and slip risk is assessed. Specifically, it is hypothesized that an increased worn region size leads to an increase in under-shoe fluid pressure, which...

Ericoid mycorrhizal shrubs alter the relationship between tree mycorrhizal dominance and soil carbon and nitrogen

Elisabeth Ward, Marlyse Duguid, Sara Kuebbing, James Lendemer, & Mark Bradford
1. Plant-fungal associations strongly influence forest carbon and nitrogen cycling. The prevailing framework for understanding these relationships is through the relative abundance of arbuscular (AM) versus ectomycorrhizal (EcM) trees. Ericoid mycorrhizal (ErM) shrubs are also common in forests and interactions between co-occurring ErM shrubs and AM and EcM trees could shift soil biogeochemical responses. Here we test hypotheses that the effects of ErM shrubs on soil carbon and nitrogen either extend or are redundant with...

Traction performance across the life of slip-resistant footwear

Kurt Beschorner, Sarah L. Hemler, Joel M. Haight, Mark S. Redfern, Jessica R. Sider & Erika M. Pliner
Slips, trips, and falls are a major cause of injury in the workplace. Footwear is an important factor in preventing slips. Furthermore, traction performance (friction and under-shoe fluid drainage) are believed to change throughout the life of footwear. However, a paucity of data is available for how traction performance changes for naturally worn, slip-resistant footwear. Participants wore slip-resistant footwear while their distance walked was monitored. Friction and under-shoe fluid pressures were measured using a robotic...

Changes in under-shoe traction and fluid drainage for progressively worn shoe tread

Kurt E. Beschorner, Sarah L. Hemler, Danielle N. Charbonneau, Arian Iraqi, Mark S. Redfern, Joel M. Haight & Brian E. Moyer
Slip and fall accidents are a common cause of injuries in the workplace. Slip-resistant footwear offers the potential to reduce the risk of these accidents. However, the efficacy of these shoes is reduced as shoes become worn. This data set provides the key independent and dependent variables from a study to evaluate the changes in traction performance of slip-resistant shoes as they become worn. The traction performance of five shoes were tracked as these shoes...

An annotated set of audio recordings of Eastern North American birds containing frequency, time, and species information

Lauren M. Chronister, Tessa A. Rhinehart, Aidan Place & Justin Kitzes
Acoustic recordings of soundscapes are an important category of audio data which can be useful for answering a variety of questions, and an entire discipline within ecology, dubbed “soundscape ecology,” has risen to study them. Bird sound is often the focus of studies of soundscapes due to the ubiquitousness of birds in most terrestrial environments and their high vocal activity. Autonomous acoustic recorders have increased the quantity and availability of recordings of natural soundscapes while...

The soil microbiome increases plant survival and modifies interactions with root endosymbionts in the field

Corlett Wood, Shaniya Markalanda, Connor McFadden & Steven Cassidy
Evidence is accumulating that the soil microbiome—the community of microorganisms living in soils—has a major effect on plant traits and fitness. However, most work to date has taken place under controlled laboratory conditions and has not experimentally disentangled the effect of the soil microbiome on plant performance from the effects of key endosymbiotic constituents. As a result, it is difficult to extrapolate from existing data to understand the role of the soil microbiome in natural...

Data from: Colour use by tiny predators: jumping spiders exhibit colour biases during foraging

Lisa Taylor, Emily Maier, Kevin Byrne, Zareen Amin & Nathan Morehouse
The evolution of many animal colours is thought to be driven by selection from visually guided predators. Yet research has largely focused on large vertebrate predators such as birds while ignoring smaller, terrestrial invertebrate predators. This is despite clear evidence that small invertebrate predators are important regulators of prey densities in a variety of ecosystems. Jumping spiders are small voracious predators that feed on a wide variety of prey in the field. They are capable...

Data from: eIF4E S209 phosphorylation licenses myc- and stress-driven oncogenesis

Jian Yu & Hang Ruan
Mutational activation of Wnt/Myc and RAS signaling promotes colorectal cancer (CRC) development and deregulates translation. Phosphorylation of the cap binding protein eIF4E (Serine 209) is commonly elevated in cancer such as CRC yet dispensable for normal development. To better understand an oncogenic role of eIF4ES209, we generated eIF4E (S209A/+) heterozygous knockin (4EKI) HCT 116 human colorectal cancer (CRC) cells. 4EKI had little or no effect on total eIF4E levels, cap binding or global translation, while...

Targeting metabotropic glutamate receptor 4 for cancer immunotherapy

Zhuoya Wan
The complex mechanism regulating the immunosuppressive tumor microenvironment (TME) remains poorly understood. Here, we reported a novel role of the metabotropic glutamate receptor-4 (GRM4) in suppressing the anti-tumor immunity. We revealed in three murine syngeneic tumor models (B16, MC38, and 3LL) that either genetic knockout (Grm4−/−) or pharmacological inhibition led to significant delay in tumor growth and synergized with immune checkpoint inhibitors in male mice. Mechanistically, perturbation of GRM4 resulted in a strong anti-tumor immunity...

Pollinators mediate floral microbial diversity and network under agrochemical disturbance

Na Wei, Avery Russell, Abigail Jarrett & Tia-Lynn Ashman
How pollinators mediate microbiome assembly in the anthosphere is a major unresolved question of theoretical and applied importance in the face of anthropogenic disturbance. We addressed this question by linking visitation of diverse pollinator functional groups (bees, wasps, flies, butterflies, beetles, true bugs and other taxa) to the key properties of floral microbiome (microbial α- and β-diversity and microbial network) under agrochemical disturbance, using a field experiment of bactericide and fungicide treatments on cultivated strawberries...

Interferon beta drives intestinal regeneration after radiation

Jian Yu & Brian Leibowitz
The cGAS-STING cytosolic DNA sensing pathway is critical for host defense. Here, we report that cGAS-STING–dependent type 1 interferon (IFN) response drives intestinal regeneration and animal recovery from radiation injury. STING deficiency has no effect on radiation-induced DNA damage or crypt apoptosis but abrogates epithelial IFN beta production, local inflammation, innate transcriptional response, and subsequent crypt regeneration. cGAS KO, IFNAR1 KO, or CCR2 KO also abrogates radiation-induced acute crypt inflammation and regeneration. Impaired intestinal regeneration...
