Artificial night light helps account for observer bias in citizen science monitoring of an expanding large mammal population

Mark Ditmer, Fabiola Iannarilli, Andrew Tri, David Garshelis & Neil Carter
1. The integration of citizen scientists into ecological research is transforming how, where, and when data are collected, and expanding the potential scales of ecological studies. Citizen-science projects can provide numerous benefits for participants, while educating and connecting professionals with lay audiences, potentially increasing acceptance of conservation and management actions. However, for all the benefits, collection of citizen-science data is often biased towards areas that are easily accessible (e.g. developments and roadways), and thus data...

Data from: Crop production in the USA is frequently limited by a lack of pollinators

James Reilly, Derek Artz, David Biddinger, Kyle Bobiwash, Natalie Boyle, Claire Brittain, Julia Brokaw, Josh Campbell, Jaret Daniels, Elizabeth Elle, Jamie Ellis, Shelby Fleischer, Jason Gibbs, Robert Gillespie, Knute Gundersen, Larry Gut, George Hoffman, Neelendra Joshi, Ola Lundin, Keith Mason, Carley McGrady, Steve Peterson, Theresa Pitts-Singer, Sujaya Rao, Nikki Rothwell … & Rachael Winfree
Most of the world’s crops depend on pollinators, so declines in both managed and wild bees raise concerns about food security. However, the degree to which insect pollination is actually limiting current crop production is poorly understood, as is the role of wild species (as opposed to managed honey bees) in pollinating crops, particularly in intensive production areas. We established a nation-wide study to assess the extent of pollinator limitation in seven crops at 131...

Tao Liu, Wenjia Liang, Haojie Zhong, Jianfeng He, Zihui Chen, Guanhao He, Tie Song, Shaowei Chen, Ping Wang, Jialing Li, Yunhua Lan, Mingji Cheng, Jinxu Huang, Jiwei Niu, Liang Xia, Jianpeng Xiao, Jianxiong Hu, Lifeng Lin, Qiong Huang, Zuhua Rong, Aiping Deng, Weilin Zeng, Jiansen Li, Xing Li, Xiaohua Tan … & Wenjun Ma
This study aimed to estimate the attack rates, and identify the risk factors of COVID-19 infection. Based on a retrospective cohort study, we investigated 11,580 contacts of COVID-19 cases in Guangdong Province from 10 January to 15 March 2020. All contacts were tested by RT-PCR to detect their infection of SARS-COV-2. Attack rates by characteristics were calculated. Logistic regression was used to estimate the risk factors of infection for COVID-19. A total of 515 of...

Nutritional constraints on brain evolution: sodium and nitrogen limit brain size

Emilie Snell-Rood, Eli Matthew Swanson, Anne Espeset, Sarah Jaumann, Kinsey Philips, Courtney Walker, Brandon Semke, Akira Mori, Gerhard Boenisch, Jens Kattge, Eric Seabloom & Elizabeth Borer
Nutrition has been hypothesized as an important constraint on brain evolution. However, it is unclear whether the availability of specific nutrients or the difficulty of locating high quality diets limits brain evolution, especially over long periods of time. We show that dietary nutrient content predicted brain size across 42 species of butterflies. Brain size, relative to body size, was associated with the sodium and nitrogen content of a species’ diet. There was no evidence that...

Development of whole-genome prediction models to increase the rate of genetic gain in intermediate wheatgrass (Thinopyrum intermedium) breeding

Jared Crain, Atena Haghighattalab, Lee DeHaan & Jesse Poland
The development of perennial grain crops is driven by the vision of simultaneous food production and enhanced ecosystem services. Typically, perennial crops like intermediate wheatgrass (IWG, Thinopyrum intermedium) have low seed yield and other detrimental agronomic traits. Next generation sequencing has made genomic selection (GS) a tractable and viable breeding method. To investigate how an IWG breeding program may utilize GS, we evaluated 3,658 plants over two years for 46 traits to build a training...

Sexual signal loss, pleiotropy, and maintenance of a male reproductive polymorphism in crickets

Justa Heinen-Kay, Rachel Nichols & Marlene Zuk
Pleiotropy between male signals and female preferences can facilitate evolution of sexual communication by maintaining coordination between the sexes. Alternatively, it can favor variation in the mating system, such as a reproductive polymorphism. It is unknown how common either of these scenarios are in nature. In Pacific field crickets (Teleogryllus oceanicus) on Kauai, Hawaii, a mutation (flatwing) that segregates as a single locus is responsible for the rapid loss of song production in males. We...

APAL 2019: Postural Data, Game Performance, and Subjective Responses of Cybersickness in Virtual Reality Head-Mounted Displays

Christopher Curry, Ruixuan Li, Nicolette Peterson & Thomas Stoffregen
Cybersickness is a subset of motion sickness and is experienced by users after they are immersed in a computer-generated virtual environment. Prior motion sickness research has shown that individuals that become motion sick display distinct kinematic patterns that differ from those that do not become sick. For this reason, kinematic data were collected before virtual reality (VR) exposure, and during exposure. Following exposure, some participants reported motion sickness. Subjects that reported motion sickness were classified...

Substrate quality drives fungal necromass decay and decomposer community structure under contrasting vegetation types

Katilyn Beidler, Richard Phillips, Erin Andrews, François Maillard, Ryan Mushinski & Peter Kennedy
1. Fungal mycelium is increasingly recognized as a central component of soil biogeochemical cycling, yet our current understanding of the ecological controls on fungal necromass decomposition is limited to single sites and vegetation types. 2. By deploying common fungal necromass substrates in a temperate oak savannah and hardwood forest in the midwestern USA, we assessed the generality of the rate at which high- and low-quality fungal necromass decomposes; further, we investigated how the decomposer ‘necrobiome’...

Consequences of drought severity for tropical live oak (Quercus oleoides) in Mesoamerica

Serge Rambal, Jeannine Cavender-Bares, Kimberlee Sparks & Jed Sparks
In two Costa Rican and three Honduran sites that vary in rainfall and soil properties, we used natural isotopes, a soil water balance model and climate-based drought indices to study shifts in water use with ontogeny from seedlings to mature tropical live oak (Quercus oleoides) trees. Water use patterns help to explain persistence of this broadly distributed species in Mesoamerica and to evaluate likely threats of on-going climate changes. At the end of dry seasons,...

Data from: The effect of autopolyploidy on population genetic signals of hard sweeps

Patrick Monnahan & Yaniv Brandvain
Searching for population genomic signals left behind by positive selection is a major focus of evolutionary biology, particularly as sequencing technologies develop and costs decline. The effect of the number of chromosome copies (i.e. ploidy) on the manifestation of these signals remains an outstanding question, despite a wide appreciation of ploidy being a fundamental parameter governing numerous biological processes. We clarify the principal forces governing the differential manifestation and persistence of the signal of selection...

Complete Data and Analysis for: Constraining invader dominance: Effects of repeated herbicidal management and environmental factors on curlyleaf pondweed dynamics in 50 Minnesota lakes

Michael Verhoeven, Daniel J Larkin & Raymond M Newman
Curlyleaf pondweed (Potamogeton crispus) is one of the most widespread and widely managed aquatic invasive plants in North America. Despite decades of management, the efficacy of long-term management strategies and the effects of environmental drivers on curlyleaf pondweed populations remain uncertain. To evaluate the effects of management and environmental factors on within-lake distribution and local density of curlyleaf pondweed, we collated monitoring data from aquatic plant point-intercept surveys collected by a variety of lake managers...

Judith Sitters, E.R. Jasper Wubs, Elisabeth S. Bakker, Thomas W. Crowther, Peter B. Adler, Sumanta Bagchi, Jonathan D. Bakker, Lori Biederman, Elizabeth T. Borer, Elsa E. Cleland, Nico Eisenhauer, Jennifer Firn, Laureano Gherardi, Nicole Hagenah, Yann Hautier, Sarah E. Hobbie, Johannes M.H. Knops, Andrew S. MacDougall, Rebecca L. McCulley, Joslin L. Moore, Brent Mortensen, Pablo L. Peri, Suzanne M. Prober, Charlotte Riggs, Anita C. Risch … &
Grasslands have been subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils remain important reservoirs of carbon (C) and nitrogen (N). Herbivores may affect both C and N pools and these changes likely interact with increases in soil nutrient availability. Given the scale of grassland soil fluxes, such changes can have striking consequences for atmospheric C concentrations...

Leaf size of woody dicots predicts ecosystem primary productivity

Yaoqi Li, Peter Reich, Bernhard Schmid, Nawal Shrestha, Xiao Feng, Tong Lyv, Brian Maitner, Xiaoting Xu, Yichao Li, Dongting Zou, Zheng-Hong Tan, Xiangyan Su, Zhiyao Tang, Qinghua Guo, Xiaojuan Feng, Brian Enquist & Zhiheng Wang
A key challenge in ecology is to understand the relationships between organismal traits and ecosystem processes. Here, with a novel dataset of leaf length and width for 10,480 woody dicots in China and 2,374 in North America, we show that the variation in community mean leaf size is highly correlated with the variation in climate and ecosystem primary productivity, independent of plant life form. These relationships likely reflect how natural selection modifies leaf size across...

Frequent burning causes large losses of carbon from deep soil layers in a temperate savanna

Adam Francis Pellegrini, Kendra K. McLauchlan, Sarah E. Hobbie, Michelle C. Mack, Abbey L. Marcotte, David M. Nelson, Steven Perakis, Peter B. Reich & Kyle Whittinghill
1. Fire activity is changing dramatically across the globe, with uncertain effects on ecosystem processes, especially belowground. Fire‐driven losses of soil carbon (C) are often assumed to occur primarily in the upper soil layers because the repeated combustion of aboveground biomass limits organic matter inputs into surface soil. However, C losses from deeper soil may occur if frequent burning reduces root biomass inputs of C into deep soil layers or stimulates losses of C via...

Data from: Predicting range expansion of invasive species: pitfalls and best practices for obtaining biologically realistic projections

Thomas Lake, Ryan Briscoe Runquist & David Moeller
Species Distribution Models (SDM) for seven invasive plant species in North America. Species distribution models (SDMs) are widely used to forecast potential range expansion of invasive species. However, invasive species occurrence datasets often have spatial biases that may violate key SDM assumptions. We examined alternative methods of spatial bias correction and multiple methods for model evaluation for seven invasive plant species. Species SDMs include Common Tansy (Tanacetum vulgare), Wild Parsnip (Pastinaca sativa), Leafy Spurge (Euphorbia...

Data from: Ecological and social drivers of neighbor recognition and the dear enemy effect in a poison frog

James Tumulty & Mark Bee
Navigating social relationships frequently rests on the ability to recognize familiar individuals using phenotypic characteristics. Across diverse taxa, animals vary in their capacities for social recognition but the ecological and social sources of selection for recognition are often unclear. In a comparative study of two closely related species of poison frogs, we identified a species difference in social recognition of territory neighbors and investigated potential sources of selection underlying this difference. In response to acoustic...

Context-dependent effects of relative temperature extremes on bill morphology in a songbird

Katie LaBarbera, Kyle J. Marsh, Kia R. R. Hayes & Talisin T. Hammond
Species increasingly face environmental extremes. While responses of morphological traits to changes in average environmental conditions are well-documented, responses to environmental extremes remain poorly understood. Bird bills contribute to thermoregulation, with considerable heat loss possible through the bill surface, and with bill morphology shaped by long-term thermal conditions. We used museum specimens to investigate the relationship of bill surface area (SA) in dark-eyed juncos Junco hyemalis to traditional measures of climate (temperature and precipitation) and...

The emerging COVID-19 caused by SARS-CoV-2 infection poses severe challenges to global public health. Serum antibody testing is becoming one of the critical methods for the diagnosis of COVID-19 patients. We investigated IgM and IgG responses against SARS-CoV-2 nucleocapsid (N) and spike (S) protein after symptom onset in the intensive care unit (ICU) and non-ICU patients. 130 blood samples from 38 COVID-19 patients were collected. The levels of IgM and IgG specific to N and...

Histological dataset for: Osteohistological analyses reveal diverse strategies of theropod dinosaur body-size macroevolution

Thomas Cullen, Juan Canale, Sebastián Apesteguía, Nathan Smith, Dongyu Hu & Peter Makovicky
The independent evolution of gigantism among dinosaurs has been a topic of longstanding interest, but it remains unclear if gigantic theropods, the largest bipeds in the fossil record, all achieved massive sizes in the same manner, or through different strategies. We perform multi-element histological analyses on a phylogenetically broad dataset sampled from eight theropod families, with a focus on gigantic tyrannosaurids and carcharodontosaurids, to reconstruct the growth strategies of these lineages and test if particular...

Molecular characteristics of eae-positive clinical Shiga toxin-producing Escherichia coli in Sweden

Ying Hua, Xiangning Bai, Ji Zhang, Cecilia Jernberg, Milan Chromek, Sverker Hansson, Anne Frykman, Xi Yang, Yanwen Xiong, Chengsong Wan & Andreas Matussek
Shiga toxin (Stx)-producing Escherichia coli (STEC) can cause a wide range of symptoms from asymptomatic carriage, mild diarrhea to bloody diarrhea (BD) and hemolytic uremic syndrome (HUS). Intimin, encoded by the eae gene, also plays a critical role in STEC pathogenesis. Herein, we investigated the prevalence and genetic diversity of eae among clinical STEC isolates from patients with diarrhea, BD, HUS as well as from asymptomatic STEC-positive individuals in Sweden with whole-genome sequencing. We found...

Asymmetric interspecific competition drives shifts in signalling traits in fan-throated lizards

Amod Zambre
Interspecific competition can occur when species are unable to distinguish between conspecific and heterospecific mates or competitors when they occur in sympatry. Selection in response to interspecific competition can lead to shifts in signalling traits - a process termed as agonistic character displacement. In two fan-throated lizard species- Sitana laticepsand Sarada darwini, females are morphologically indistinguishable and male agonistic signalling behaviour is similar. Consequently, in areas where these species overlap, males engage in interspecific aggressive...
