Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: A global dataset for economic losses of extreme hydrological events during 1960-2014

Bo Tao, Liping Gao, Yunxuan Miao, Lihua Zhang, Xia Song, Wei Ren, Liyuan He & Xiaofeng Xu
A comprehensive dataset of extreme hydrological events (EHEs) – floods and droughts, consisting of 2,171 occurrences worldwide, during 1960‐2014 was compiled, and then their economic losses were normalized using a price index in U.S. dollar. The dataset showed a significant increasing trend of EHEs before 2000, while a slight post‐2000 decline. Correspondingly, the EHEs‐caused economic losses increased obviously before 2000 followed by a slight decrease; the post‐2000 decline could be partially attributed to the decreases...

Data from: Meta-analysis of yield response of foliar fungicide-treated hybrid corn in the United States and Ontario, Canada

Kiersten A. Wise, Damon L. Smith, Anna Freije, Daren S. Mueller, Yuba Kandel, Tom Allen, Carl A. Bradley, Emmanuel Byamukama, Martin Chilvers, Travis Faske, Andrew Friskop, Clayton Hollier, Tamra A. Jackson-Ziems, Heather Kelly, Bob Kemerait, Paul Price, Alison Robertson & Albert Tenuta
Background: Foliar fungicide applications to corn (Zea mays) occur at one or more application timings ranging from early vegetative growth stages to mid-reproductive stages. Previous studies indicated that fungicide applications are profitable under high disease pressure when applied during the tasseling to silking growth stages. Few comprehensive studies in corn have examined the impact of fungicide applications at an early vegetative growth stage (V6) compared to late application timings (VT) for yield response and return...

Data from: Meta-analytic and economic approaches for evaluation of pesticide impact on Sclerotinia stem rot control and soybean yield in the North Central U.S.

Jaime F. Willbur, Paul Mitchell, Mamadou L. Fall, Adam M. Byrne, Scott Chapman, Crystal M. Floyd, Carl A. Bradley, Keith Ames, Martin I. Chilvers, Nathan Kleczewski, Dean Malvick, Brian Mueller, Daren Mueller, Mehdi Kabbage, Shawn P. Conley & Damon Smith
As complete host resistance in soybean has not been achieved, Sclerotinia stem rot (SSR) caused by Sclerotinia sclerotiorum continues to be of major economic concern for farmers. Thus, chemical control remains a prevalent disease management strategy. Pesticide evaluations were conducted in Illinois, Iowa, Michigan, Minnesota, New Jersey, and Wisconsin from 2009 to 2016, for a total of 25 site-years (n = 2057 plot-level data points). These studies were used in network meta-analyses to evaluate the...

Data from: Replicated latitudinal clines in reproductive traits of European and North American yellow dung flies

Stephanie S. Bauerfeind, Martin A. Schäfer, David Berger, Wolf U. Blanckenhorn & Charles W. Fox
Geographic variation in phenotypic traits is commonly correlated with spatial variation in the environment, e.g., seasonality and mean temperature, providing evidence that natural selection generates such patterns. In particular, both body size and egg size of ectothermic animals are commonly larger in northern climates, and temperature induces plastic responses in both traits. Size-independent egg quality can also vary with latitude, though this is rarely investigated. For the widespread yellow dung fly (Scathophaga stercoraria; Diptera: Scathophagidae),...

Sex, hormone status, and growth rate influence dietary isotope fractionation in laboratory rats

Sora Kim & Jessica Santollo
Stable isotope analysis of rat tissues to determine effects of gonadectomization. Four groups - female, ovarectomized, male, and castrated male - were fed a constant diet for 30 days. Fat, muscle, liver, and kidney were sampled at the experiment's end while serum and blood were sampled at days 0, 1, and 30. We found that sex and removal of gonadal hormones are factors either individually or interactive for carbon and nitrogen stable isotope composition in...

Data from: Quantifying climate sensitivity and climate-driven change in North American amphibian communities

David A. W. Miller, Evan H. Campbell Grant, Erin Muths, Staci M. Amburgey, Michael J. Adams, Maxwell B. Joseph, J. Hardin Waddle, Pieter T. J. Johnson, Maureen E. Ryan, Benedikt R. Schmidt, Daniel L. Calhoun, Courtney L. Davis, Robert N. Fisher, David M. Green, Blake R. Hossack, Tracy A. G. Rittenhouse, Susan C. Walls, Larissa L. Bailey, Sam S. Cruickshank, Gary M. Fellers, Thomas A. Gorman, Carola A. Haas, Ward Hughson, David S. Pilliod, Steven J. Price … & Brent H. Sigafus
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81 species across 86 North American study areas. The effect of climate on local colonization and persistence probabilities varies among eco-regions and depends on local...

Relatedness and the composition of communities over time: evaluating phylogenetic community structure in the late Cenozoic record of bivalves

Lucy Chang & Phillip Skipwith
Understanding the mechanisms that prevent or promote the coexistence of taxa at local scales is critical to understanding how biodiversity is maintained. Competitive exclusion and environmental filtering are two processes thought to limit which taxa become established in a community. However, determining the relative importance of the two processes is a complex task, especially when the critical initial stages of colonization cannot be directly observed. Here, we explore the use of phylogenetic community structure for...

Comparative Studies of Reproductive Diapause in North American Populations of Three Hippodamia Species (Coleoptera: Coccinellidae)

John Obrycki
Adult Hippodamia parenthesis were collected from McLean County, Illinois (40.34°N, 88.77°W), Johnson County, Iowa (41.67°N, 91.52°N), Onondaga County, New York (43.03°N, 76.00°W) and Jefferson County, New York (43.98°N, 75.91°W) (Supplemental Figure 1). Eggs were collected daily from 4 to 6 females in each population and placed in L:D 16:8, 14:10, 12:12,10:14, at 22°C ± 1.0°C. F1 offspring were individually reared in glass vials at each photoperiod on pea aphids and Ephestia kuehniella eggs to examine...

The Pacific lamprey genomic divergence, association mapping, temporal Willamette Falls, spatial rangewide datasets

Jon Hess, Jeramiah Smith, Nataliya Timoshevskaya, Cyndi Baker, Christopher Caudill, David Graves, Matthew Keefer, Andrew Kinziger, Mary Moser, Laurie Porter, Greg Silver, Steven Whitlock & Shawn Narum
High rates of dispersal can breakdown coadapted gene complexes. However, concentrated genomic architecture (i.e., genomic islands of divergence) can suppress recombination to allow evolution of local adaptations despite high gene flow. Pacific lamprey (Entosphenus tridentatus) is a highly dispersive anadromous fish. Observed trait diversity and evidence for genetic basis of traits suggests it may be locally adapted. We addressed whether concentrated genomic architecture could influence local adaptation for Pacific lamprey. Using two new whole genome...

Endosymbionts facilitate rapid evolution in a polyphagous herbivore

Paul Lenhart & Jennifer White
Maternally transmitted bacterial symbionts can be important mediators of the interactions between insect herbivores and their foodplants. These symbionts are often facultative (present in some host individuals but not others) and can have large effects on their host’s phenotype, thus giving rise to heritable variation upon which selection can act. In the cowpea aphid (Aphis craccivora) it has been established that the facultative endosymbiont Arsenophonus improves aphid performance on black locust trees (Robinia pseudoacacia) but...

The evolution of broadly polylectic behaviour in Lasioglossum (Chilalictus) (Halictidae, Apoidea)

Trace Akankunda, Carlos Rodriguez Lopez, Remko Leijs & Ken Walker
Based on the number of pollen hosts utilised, bees have been categorised as generalists (polylectic) or specialists (oligolectic). Faced with a changing habitat, polylectic bees can diversify their pollen ‘portfolio’, while oligolectic bees cannot and therefore may go locally extinct. Research into the evolution and maintenance of broad polylecty is scant. Instead, research has mainly focussed on the factors that constrain oligolectic species to a narrow diet. Here, we developed a molecular phylogeny of a...

Data from: Diverse and complex muscle spindle afferent firing properties emerge from multiscale muscle mechanics

Kyle Blum, Brian Horslen, Kenneth Campbell, Brian Horslen, Paul Nardelli, Stephen Housley, Timothy Cope & Lena Ting
Despite decades of research, we lack a mechanistic framework capable of predicting how movement-related signals are transformed into the diversity of muscle spindle afferent firing patterns observed experimentally, particularly in naturalistic behaviors. Here, a biophysical model demonstrates that well-known firing characteristics of mammalian muscle spindle Ia afferents – including movement history dependence, and nonlinear scaling with muscle stretch velocity – emerge from first principles of muscle contractile mechanics. Further, mechanical interactions of the muscle spindle...

Irreproducibility in searches of scientific literature: a comparative analysis

Gabor Pozsgai, Gabor Lövei, Liette Vasseur, Geoff Gurr, Péter Batáry, Janos Korponai, Nick Littlewood, Jian Liu, Arnold Móra, John Obrycki, Olivia Reynolds, Jenni Stockan, Heather VanVolkenburg, Jie Zhang, Wenwu Zhou & Minsheng You
1. Repeatability is the cornerstone of science and it is particularly important for systematic reviews. However, little is known on how researchers’ choice of database and search platform influence the repeatability of systematic reviews. Here, we aim to unveil how the computer environment and the location where the search was initiated from influence hit results. 2. We present a comparative analysis of time-synchronized searches at different institutional locations in the world, and evaluate the consistency...

Pathotype complexity and genetic characterization of Phytophthora sojae populations in Illinois, Indiana, Kentucky, and Ohio

Linda Hebb, Carl A. Bradley, Santiago Xavier Mideros, Darcy E. P. Telenko, Kiersten Wise & Anne Elizabeth Dorrance
Phytophthora sojae, the causal agent of Phytophthora root and stem rot of soybean, has been managed with single Rps genes since the 1960’s, but has subsequently adapted to many of these resistance genes, rendering them ineffective. The objective of this study was to examine the pathotype and genetic diversity of P. sojae from soil samples across Illinois, Indiana, Kentucky, and Ohio by assessing which Rps gene(s) were still effective and identifying possible population clusters. There...

Supplementary material and supplementary data files for: Handling logical character dependency in phylogenetic inference: Extensive performance testing of assumptions and solutions using simulated and empirical data

Tiago R. Simões, Oksana Vernygora, Bruno A. S. Medeiros & April M. Wright
Logical character dependency is a major conceptual and methodological problem in phylogenetic inference of morphological datasets, as it violates the assumption of character independence that is common to all phylogenetic methods. It is more frequently observed in higher-level phylogenies or in datasets characterizing major evolutionary transitions, as these represent parts of the tree of life where (primary) anatomical characters either originate or disappear entirely. As a result, secondary traits related to these primary characters become...
