The datasets used in this study are provided in 7 folders: “dataset A”, containing data from Sandwich Town Neck Beach on Cape Cod, Massachusetts. These images are published as a USGS data series (Sherwood et al., 2021) are publicly available at https://doi.org/10.5066/P9BFD3YH “dataset B”, containing data from North and South Carolina collected immediately after Hurricane Florence in October 2018.

Willow Flycatcher subspecies song discrimination experiment data

Sean Mahoney
Animals use acoustic signals to repel competitors and attract mates, and signal divergence among populations can promote reproductive isolation. Empidonax flycatchers are insectivorous passerine birds distributed across North and Central America that are conservative in plumage but often exhibit differences in song both between and within species. Four subspecies have been recognized within the Willow Flycatcher (Empidonax traillii) and previous analyses have revealed differences in song structure among a subset of these. Using reciprocal playback...

NEON forest and woodland plots: diversity, structure and climate

Christopher Hakkenberg
We combined climate variables with field measurements and airborne lidar from all forest and woodland plots in the National Ecological Observatory Network (NEON) to characterize the role of climate in constraining biodiversity – forest structure relationships across the United States.

Variations and controlling factors of soil denitrification rate

The denitrification process profoundly affects soil nitrogen (N) availability and generates its byproduct, nitrous oxide, as a potent greenhouse gas. There are large uncertainties in predicting global denitrification because its controlling factors remain elusive. In this study, we compiled 4301 observations of denitrification rates across a variety of terrestrial ecosystems from 214 papers published in the literature. The averaged denitrification rate was 3516.3 ± 91.1 µg N kg−1 soil day−1. The highest denitrification rate was...

Residual force enhancement is reduced in permeabilized fiber bundles from mdm muscles

Kiisa Nishikawa, Dhruv Mishra & Kiisa C Nishikawa
Residual force enhancement (RFE) is the increase in steady-state force after active stretch relative to the force after isometric contraction at the same final length. The mdm mutation in mice, characterized by a small deletion in N2A titin, has been proposed to prevent N2A titin-actin interactions so that active mdm muscles are more compliant than WT. This decrease in active muscle stiffness should be associated with reduced RFE. We investigated RFE in permeabilized soleus (SOL)...

Selection and evolution at the community level using common garden data

Stephen Shuster, Arthur Keith & Thomas Whitham
A key issue in evolutionary biology is whether selection acting at levels higher than the individual can cause evolutionary change. If it can, then conceptual and empirical studies must consider how selection operates at multiple levels of biological organization. Here, we test the hypothesis that estimates of broad-sense community heritability, H2C, can be used to predict the evolutionary response by community-level phenotypes when community-level selection is imposed. Using an approach informed by classic quantitative genetics,...

A genomic perspective on the evolutionary diversification of turtles

Simone Gable, Michael Byars, Robert Literman & Marc Tollis
To examine phylogenetic heterogeneity in turtle evolution, we collected thousands of high-confidence single-copy orthologs from 19 genome assemblies representative of extant turtle diversity and estimated a phylogeny with multispecies coalescent and concatenated partitioned methods. We also collected next-generation sequences from 26 turtle species and assembled millions of biallelic markers to reconstruct phylogenies based on annotated regions from the western painted turtle (Chrysemys picta bellii) genome (coding regions, introns, untranslated regions, intergenic, and others). We then...

Sperm limitation produces male biased family sex ratios

Stephen Shuster, Zane Holditch, Kayla Ochoa, Shauna Greene, Shay Allred & Jeffrey Baranowski
Haplo-diploid sex determination in the parasitoid wasp, Nasonia vitripennis (Walker), allows females to adjust their brood sex ratios. Females influence whether ova are fertilized, producing diploid females, or remain unfertilized, producing haploid males. Females appear to adjust their brood sex ratios to minimize “local mate competition,” i.e., competition among sons for mates. Because mating occurs between siblings, females may optimize mating opportunities for their offspring by producing only enough sons to inseminate daughters when ovipositing...
