Quarry 2 Floor Tile

Ruikang Ding, Abhijeet Gujrati, Matthew M. Pendolino, Kurt E. Beschorner & Tevis D. B. Jacobs
These are surface profiles of quarry 2 rough flooring. The quarry 1 (0T01881P, Daltile, Dallas, TX, USA) and quarry 2 (01 010 SM 1, Summitville, OH, USA) were commercial tiles, where the full composition was a trade secret, but they were known to include 15-25 wt% quartz, and quarry 2 also included abrasive grits on the surface, presumably to improve slip resistance. There are 30 profiles generated from image analysis and measured by SEM. 10...

Data from: A generalist nematode destabilizes plant competition: no evidence for direct effects, but strong evidence for indirect effects on rhizobia abundance

Samantha Catella, Castilleja Olmsted, Shaniya Markalanda, Connor McFadden, Corlett Wood & Sara Kuebbing
1. Difficulties quantifying pathogen load and mutualist abundance limit our ability to connect disease dynamics to host community ecology. For example, specific predictions about how differential pathogen load is hypothesized to drive host competitive outcomes are rarely tested. Additionally, although infection is known to affect mutualists, we rarely measure the magnitude of pathogen effects on mutualist abundance across host competitive contexts. We tested for both mechanisms in a plant-rhizobia-nematode system. 2. We paired the legume...

Supplementary information for: A continuous-score occupancy modeling framework for incorporating uncertain machine learning output in autonomous biodiversity surveys

Tessa Rhinehart, Daniel Turek & Justin Kitzes
Ecologists often study biodiversity by evaluating species occupancy and the relationship between occupancy and other covariates. Occupancy models are now widely used to account for false absences in field surveys and to reduce bias in estimates of covariate relationships. Existing occupancy models take as inputs binary detection/non-detection observations of species at each visit to each site. However, autonomous sensing devices and machine learning models are increasingly used to survey biodiversity, generating a new type of...

Data from: Shoaling guppies evade predation but have deadlier parasites

Jason Walsman, Mary Janecka, David Clark, Rachael Kramp, Faith Rovenolt, Regina Patrick, Ryan Mohammed, Mateusz Konczal, Clayton Cressler & Jessica Stephenson
We collected data on coinfection rates, infection prevalence, and infection intensity for Gyrodactylus spp. on wild Trinidadian guppies (Poecilia reticulata). We also collected data on the shoaling preference of wild-caught guppy hosts. Further, we collected data on transmission rates, infection intensity, and infected host mortality rates of lines of these parasites on guppies in the laboratory. We fouind that wild guppy populations with stronger shoaling preferences had higher infection prevalence and coinfection rates. Further, we...

Seasonality of host immunity in a tropical disease system

Jamie Voyles, Goncalo Rosa, Rachel Perez, Lora Richards, Corinne Richards-Zawacki, Angela Smilanich, Laura K. Reinert, Louise A. Rollins-Smith, Daniel Wetzel & Jamie Voyles
Infectious disease systems frequently exhibit strong seasonal patterns, yet the mechanisms that underpin intra-annual cycles are unclear, particularly in tropical regions. We hypothesized that host immune function fluctuates seasonally, contributing to oscillations in infection patterns in a tropical disease system. To test this hypothesis, we investigated a key host defense of amphibians against a lethal fungal pathogen, Batrachochytrium dendrobatidis (Bd). We integrated two field experiments in which we perturbed amphibian skin secretions, a critical host...

Synthetic self-affine topography scanned with a virtual spherical probe

Tevis D. B. Jacobs, Till Junge & Lars Pastewka
This surface contains a self-affine topography that has been scanned with a spherical virtual probe of radius 40 nm. The probe was lowered normal to the surface on each point of the reference topography (that is also included here) and the center of the probe was taken as the "measured" value of the topography. The reference topography has a Hurst exponent of 0.8 and was generated with a Fourier-filtering algorithm. This surface was used to...

Ceramic Floor Tile

Ruikang Ding, Abhijeet Gujrati, Matthew M. Pendolino, Kurt E. Beschorner & Tevis D. B. Jacobs
These are surface profiles of ceramic flooring. The ceramic tile (ADJF250803, ASTM) was a reference tile that was used in the reference standard ASTM F2508-12a. There are 30 profiles generated from image analysis and measured by SEM. 10 profiles are from 250X magnification, 10 profiles are from 5000X magnification, and 10 profiles are from 100kX magnification. There are also 6 profiles measured by stylus profilometry.

These are surface profiles of quarry 1 smooth flooring. The quarry 1 (0T01881P, Daltile, Dallas, TX, USA) and quarry 2 (01 010 SM 1, Summitville, OH, USA) were commercial tiles, where the full composition was a trade secret, but they were known to include 15-25 wt% quartz, and quarry 2 also included abrasive grits on the surface, presumably to improve slip resistance.

Complementary evolution of coding and noncoding sequence underlies mammalian hairlessness

Nathan Clark, Amanda Kowalczyk & Maria Chikina
Body hair is a defining mammalian characteristic, but several mammals, such as whales, naked mole-rats, and humans, have notably less hair than others. To find the genetic basis of reduced hair quantity, we used our evolutionary-rates-based method, RERconverge, to identify coding and noncoding sequences that evolve at significantly different rates in so-called hairless mammals compared to hairy mammals. Using RERconverge, we performed an unbiased, genome-wide scan over 62 mammal species using 19,149 genes and 343,598...

Self-affine synthetic surface

Tevis D. B. Jacobs, Till Junge & Lars Pastewka
This surface contains virtual measurements taken out of a large self-affine synthetic surface with Hurst exponent 0.8. The original surface had 50,000 x 50,000 data points and was created using a Fourier filtering algorithm. The surface was "measured" in block containing 500 x 500 data points with a variety of scan sizes ranging from almost the full surface with 100 μm width to 10 μm to 1 μm, with pixel sizes scaling accordingly. This surface...

Jason Walsman, Alexander Strauss & Spencer Hall
This contains data for the manuscript listed in the title.We measured the foraging rates of individual zooplankton hosts, Daphnia dentifera, on phytoplankton resources, Ankistrodesmus falcatus, in the presence of fungal parasites of zooplankton, Metschnikowia bicuspidata. Some of these data are previously published (Genotypes12_foraging.csv by Strauss, Alexander T., et al. "Genotypic variation in parasite avoidance behaviour and other mechanistic, nonlinear components of transmission." Proceedings of the Royal Society B 286.1915 (2019): 20192164.) and some are published...

Supplementary data, code, and information for ‘Interhemispheric antiphasing of neotropical precipitation during the past millennium’ (PNAS, Steinman et al. 2022)

B.A. Steinman, N. Stansall, M.E. Mann, C.A. Cooke, M.B. Abbott, M. Vuille, B.W. Bird, M.S. Lachniet & A. Fernandez
Uncertainty about the influence of anthropogenic radiative forcing on the position and strength of convective rainfall in the Intertropical Convergence Zone (ITCZ) inhibits our ability to project future tropical hydroclimate change in a warmer world. Paleoclimatic and modeling data inform on the timescales and mechanisms of ITCZ variability; yet a comprehensive, long-term perspective remains elusive. Here, we quantify the evolution of neotropical hydroclimate over the pre-industrial past millennium (850 to 1850 CE) using a synthesis...

Population-level variation in parasite resistance due to differences in immune initiation and rate of response

Amanda Hund, Lauren Fuess, Mariah Kenney, Meghan Maciejewski, Joseph Marini, Kum Chuan Shim & Dan Bolnick
Closely related populations often differ in resistance to a given parasite, as measured by infection success or failure. Yet, the immunological mechanisms of these evolved differences are rarely specified. Does resistance evolve via changes to the host’s ability to recognize that an infection exists, actuate an effective immune response, or attenuate that response? We tested whether each of these phases of the host response contributed to threespine sticklebacks’ recently evolved resistance to their tapeworm Schistocephalus...
