Bird records and habitat covariates databases (11 species; Oaxaca 2016-2018)

Rubén Ortega-Álvarez, Esteban Berrones Benítez, Israel Medina Mena, Viviana Ruiz-Gutiérrez & J. Jaime Zúñiga-Vega
Assessing the impact of working landscapes on biodiversity and defining locally contextualized management guidelines for productive activities are key for sustainability. Occupancy dynamics provide information about sites in the landscape that are either avoided or preferred by populations through the estimation of extinction and colonization probabilities, respectively. We identified the habitat traits that affected colonization and extinction probabilities of target birds (forest-dependent, endemic, or conservation-concern species) within a Neotropical working landscape by using multi-season occupancy...

The experimental manipulation of atmospheric drought: Teasing out the role of microclimate in biodiversity experiments

Beatriz Aguirre & Alexandra Wright
Drought occurrence is increasing due to anthropogenic climate change. Drought can negatively affect plants via reduced water belowground and increased evaporative demand or vapor pressure deficit (VPD) aboveground. Past work has shown that plant diversity can ameliorate the negative effects of drought in plant communities, but these results are inconsistent between experimental and natural drought studies. Further, while studies on the negative effects of reduced soil moisture on plant growth in drought experiments are abundant,...

Tissue-type specific accumulation of the plastoglobular proteome, transcriptional networks and plastoglobular functions

Klaas Van Wijk, Elena Michel & Lalit Ponnala
Plastoglobules (PGs) are dynamic protein-lipid micro-compartments in plastids enriched for isoprenoid-derived metabolites. Chloroplast PGs support formation, remodeling and controlled dismantling of thylakoids during developmental transitions and environmental responses. However, the specific molecular functions of most PG proteins are still poorly understood. This review harnesses recent co-mRNA expression data from combined microarray and RNAseq information in ATTED-II on an updated inventory of 34 PG proteins, as well as proteomics data across 30 Arabidopsis tissue types from...

Data for: Fire history and weather interact to determine extent and synchrony of mast-seeding in rhizomatous scrub oaks of Florida

Mario Pesendorfer, Reed Bowman, Georg Gratzer, Shane Pruett, Angela Tringali & John Fitzpatrick
In disturbance-prone ecosystems, fitness consequences of plant reproductive strategies are often determined by the relative timing of seed production and disturbance events, but the role of disturbances as proximate drivers of seed production has been overlooked. We use long-term data on seed production in Quercus chapmanii, Q. geminata, and Q. inopina, rhizomatous oaks found in Southcentral Florida’s oak scrub, to investigate the role of fire history and its interaction with weather in shaping acorn production...

Automated audio recording as a means of surveying Tinamous (Tinamidae) in the Peruvian Amazon

Reid Rumelt, Arianna Basto & Carla Mere Roncal
The use of machine learning technologies to process large quantities of remotely-collected audio data is a powerful emerging research tool in ecology and conservation. We applied these methods to a field study of tinamou (Tinamidae) biology in Madre de Dios, Peru, a region expected to have high levels of interspecies competition and niche partitioning as a result of high tinamou alpha diversity. We used autonomous recording units to gather environmental audio over a period of...

Phenotypic, fitness and environmental data in support of the publication: selection favors adaptive plasticity in a long-term reciprocal transplant experiment

Jill Anderson, M. Inam Jameel & Monica Geber
Spatial and temporal environmental variation can favor the evolution of adaptive phenotypic plasticity, such that genotypes alter their phenotypes in response to local conditions to maintain fitness across heterogeneous landscapes. When individuals show greater fitness in one habitat than another, asymmetric migration can restrict adaptation in the lower quality environment. In these cases, selection is predicted to favor traits that enhance fitness in the higher-quality habitat at the expense of fitness in the marginal habitat....

Social Interaction and Pain Threshold in Virtual Reality

Andrea Stevenson Won, Swati Pandita & Kaylee Payne Kruzan
This experiment examined the effects of social presence and perceived location of a virtual environment on participants’ pain thresholds in a pre-registered, within-subjects experiment. First, we examined the effects of social interaction vs being alone in a virtual environment. Second, we compared a virtual environment representing a remote location to a replication of the lab environment. While the "location" of the virtual environment did affect social presence, such that participants reported greater social presence with...

Habitat mediates coevolved but not novel species interactions

Joshua Twining, Chris Sutherland, Neil Reid & David Tosh
On-going recovery of native predators has the potential to alter species interactions, with community and ecosystem wide implications. We estimated co-occurrence of three species of conservation and management interest from a multi-species citizen science camera trap survey. We demonstrate fundamental differences in novel and co-evolved predator-prey interactions that are mediated by habitat. Specifically, we demonstrate that anthropogenic habitat modification had no influence on the expansion of the recovering native pine marten in Ireland, nor does...

Both consumptive and non-consumptive effects of predators impact mosquito populations and have implications for disease transmission

Marie C Russell, Catherine M Herzog, Zachary Gajewski, Chloe Ramsay, Fadoua El Moustaid, Michelle V Evans, Trishna Desai, Nicole L Gottdenker, Sara L Hermann, Alison G Power & Andrew C McCall
Predator-prey interactions influence prey traits through both consumptive and non-consumptive effects, and variation in these traits can shape vector-borne disease dynamics. Meta-analysis methods were employed to generate predation effect sizes by different categories of predators and mosquito prey. This analysis showed that multiple families of aquatic predators are effective in consumptively reducing mosquito survival, and that the survival of Aedes, Anopheles, and Culex mosquitoes is negatively impacted by consumptive effects of predators. Mosquito larval size...

Differential geographic patterns in song components of male Albert’s lyrebirds

Fiona Backhouse, Anastasia Dalziell, Robert Magrath, Aaron Rice, Taylor Crisologo & Justin Welbergen
Geographic variation in bird song has received much attention in evolutionary studies, yet few consider components within songs that may be subject to different constraints and follow different evolutionary trajectories. Here we quantify patterns of geographic variation in the socially-transmitted ‘whistle’ song of Albert’s lyrebirds (Menura alberti), an oscine passerine renowned for its remarkable vocal abilities. Albert’s lyrebirds are confined to narrow stretches of suitable habitat, allowing us to map likely paths of cultural transmission...

Cornell National Social Survey (CNSS), 2019

Cornell National Social Survey is a random-sample survey of adults aged 18 and over. In 2019, participants were asked their opinions on a range of topics.

Reproduction Materials For: Cooperation with Strangers: Spillover of Community Norms

Mario Molina, Victor Nee & Hakan Nolm
**PI-Provided Abstract**: Why do leaders of organizations cooperate with players whom they may never transact with again? Such transactions can involve the incentives to exploit the other party because these interactions are not recurrent or embedded in networks. Yet in a market economy, organizational actors learn to cooperate with strangers; otherwise they risk closure from new ideas and business opportunities outside of their local community. With a large random sample of CEOs of manufacturing firms...

Data from: Genome size influences adaptive plasticity of water loss, but not metabolic rates in lungless salamanders

Benjamin Johnson, Jeremy Searle & Jed Sparks
Many expressions of phenotype, such as physiological performance, integrate multiple underlying traits to function. Linking component traits to adaptive physiology thus gives insight into mechanisms of selection acting on performance. Genome size (C-value) is a trait that influences physiology in multiple taxa by exerting a nucleotypic effect, constraining cell size and cellular physiology such that whole-organism mass-specific metabolism is reduced with increasing C-value. We tested for this mechanism of C-value function acting in lungless salamanders,...

Supporting data for: Gene-rich UV sex chromosomes harbor conserved regulators of sexual development (Carey et al., 2021)

Sarah Carey, Shenqiang Shu, John Lovell, Avinash Shenqiang, Florian Maumus, George Tiley, Noe Fernandez-Pozo, Kerrie Barry, Cindy Chen, Mei Wang, Anna Lipzen, Chris Daum, Christopher Saski, Adam Payton, Jordan McBreen, Roth Conrad, Leslie Kollar, Sanna Olsson, Sanna Huttunen, Jacob Landis, Norman Wickett, Matthew Johnson, Stefan Rensing, Jane Grimwood, Jeremy Schmutz … & Adam Healey
Non-recombining sex chromosomes, like the mammalian Y, often lose genes and accumulate transposable elements, a process termed degeneration. The correlation between suppressed recombination and degeneration is clear in animal XY systems, but the absence of recombination is confounded with other asymmetries between the X and Y. In contrast, UV sex chromosomes, like those found in bryophytes, experience symmetrical population genetic conditions. Here we generate and use nearly gapless female and male chromosome-scale reference genomes of...

Male-like female morphs in hummingbirds: the evolution of a widespread sex-limited plumage polymorphism

Eleanor Diamant, Jay J. Falk & Dustin R. Rubenstein
Differences in the way males and females look or behave are common in animals. However, discrete variation within sexes (sex-limited polymorphism) also occurs in several vertebrate and invertebrate lineages. In birds, female-limited polymorphism (FLP) in which some females resemble males in coloration is most prominent in hummingbirds, a group known for its morphological and behavioural sexual dimorphism. Yet, it remains unclear whether this intrasexual colour variation in hummingbirds arises through direct selection on females, or...

Did shell-crushing predators drive the evolution of ammonoid septal shape?

Erynn Johnson, Briana DiMarco, David Peterman, Aja Carter & Warren Allmon
For centuries, paleontologists have sought functional explanations for the uniquely complex internal walls (septa) of ammonoids, extinct shelled cephalopods. Ammonoid septa developed increasingly complex fractal margins, unlike any modern shell morphologies, throughout more than 300 million years of evolution. Some have suggested these morphologies provided increased resistance to shell-crushing predators. We perform the first physical compression experiments on model ammonoid septa using controlled, theoretical morphologies generated by computer-aided design and 3D printing. These biomechanical experiments...

Supporting Data for: Differential gene expression associated with a floral scent polymorphism in the evening primrose Oenothera harringtonii (Onagraceae)

Norman Wickett, Lindsey Bechen, Geoffrey Broadhead, Rachel Levin, Rick Overson, Tania Jogesh, Jeremie Fant, Robert Raguso & Krissa Skogen
Background: Plant volatiles play an important role in both plant-pollinator and plant-herbivore interactions. Intraspecific polymorphisms in volatile production are ubiquitous, but studies that explore underlying differential gene expression are rare. Oenothera harringtonii populations are polymorphic in floral emission of the monoterpene (R)-(-)-linalool; some plants emit (R)-(-)-linalool (linalool+ plants) while others do not (linalool- plants). However, the genes associated with differential production of this floral volatile in Oenothera are unknown. We used RNA-Seq to broadly characterize...

Evolutionary tradeoffs between male secondary sexual traits revealed by a phylogeny of the hyperdiverse tribe Eumaeini (Lepidoptera: Lycaenidae)

Wendy A. Valencia-Montoya, Tiago B. Quental, João Filipe R. Tonini, Gerard Talavera, James D. Crall, Gerardo Lamas, Robert C. Busby, Ana Paula S. Carvalho, Ana B. Morais, Nicolás Oliveira Mega, Helena Piccoli Romanowski, Marjorie A. Liénard, Shayla Salzman, Melissa R. L. Whitaker, Akito Y. Kawahara, David J. Lohman, Robert K. Robbins & Naomi E. Pierce
Male butterflies in the hyperdiverse tribe Eumaeini possess an unusually complex and diverse repertoire of secondary sexual characteristics involved in pheromone production and dissemination. Maintaining multiple sexually selected traits is likely to be metabolically costly, potentially resulting in trade-offs in the evolution of male signals. However, a phylogenetic framework to test hypotheses regarding the evolution and maintenance of male sexual traits in Eumaeini has been lacking. Here, we infer a comprehensive, time-calibrated phylogeny from 379...

X-Ray CT scans of barley panicles and their individual seeds from the Composite Cross II experiment

Erik Amézquita, Michelle Quigley, Tim Ophelders, Jacob Landis, Daniel Koenig, Elizabeth Munch & Daniel Chitwood
Shape plays a fundamental role in biology. Traditional phenotypic analysis methods measure some features but fail to measure the information embedded in shape comprehensively. To extract, compare, and analyze this information embedded in a robust and concise way, we turn to Topological Data Analysis (TDA), specifically the Euler Characteristic Transform. TDA measures shape comprehensively using mathematical representations based on algebraic topology features. To study its use, we compute both traditional and topological shape descriptors to...

Integrating ecosystem metabolism and consumer allochthony reveals nonlinear drivers in lake organic matter processing

Meredith Holgerson, Rachel Hovel, Patrick Kelly, Lauren Bortolotti, Jennifer Brentrup, Amber Bellamy, Samantha Oliver & Alexander Reisinger
Lakes process both terrestrial and aquatic organic matter, and the relative contribution from each source is often measured via ecosystem metabolism and terrestrial resource use in the food web (i.e., consumer allochthony). Yet, ecosystem metabolism and consumer allochthony are rarely considered together, despite possible interactions and potential for them to respond to the same lake characteristics. In this study, we compiled global datasets of lake gross primary production (GPP), ecosystem respiration (ER), and zooplankton allochthony...

Bird strikes at commercial airports explained by citizen science and weather radar data

Cecilia Nilsson, Frank La Sorte, Adriaan Dokter, Kyle Horton, Benjamin Van Doren, Jeffrey Kolodzinski, Judy Shamoun-Baranes & Andrew Farnsworth
1. Aircraft collisions with birds span the entire history of human aviation, including fatal collisions during some of the first powered human flights. Much effort has been expended to reduce such collisions, but increased knowledge about bird movements and species occurrence could dramatically improve decision support and proactive measures to reduce them. Migratory movements of birds pose a unique, often overlooked, threat to aviation that is particularly difficult for individual airports to monitor and predict:...

Social and abiotic factors differentially affect plumage ornamentation of young and old males in an Australian songbird

Joseph F. Welklin, Samantha M. Lantz, Sarah Khalil, Nicole M. Moody, Jordan Karubian & Michael S. Webster
Both abiotic environmental conditions and variation in social environment are known to impact the acquisition of sexual signals. However, the influences of abiotic environmental and social factors are rarely compared to each other. Here we test the relative importance of these factors in determining whether and when male red-backed fairywrens (Malurus melanocephalus) moult into a known sexual signal, ornamented breeding plumage. One-year-old male red-backed fairywrens vary in whether or not they acquire ornamentation, whereas males...

Natural causes of white-tailed deer morbidity and mortality in New York State

Sophie Zhu, Elizabeth Buckles, Elizabeth Bunting, Kevin Hynes & Krysten Schuler
White-tailed deer Odocoileus virginianus are the most popular big game animal in the United States. Recreational harvest of these animals is a critical tool in population management, as well as an important financial resource for state economies and wildlife agencies. Thus, herd health evaluations can provide information to wildlife managers tasked with developing sustainable harvest practices while monitoring for emergent problems. The purpose of our study was to document causes of illness and natural mortality...

Experimental evaluation of herbicide use on biodiversity, ecosystem services, and timber production tradeoffs in forest plantations

Thomas Stokely, Urs Kormann, Jake Verschuyl, Andrew Kroll, David Frey, Scott Harris, Doug Mainwaring, Douglas Maguire, Jeff Hatten, James Rivers, Stephen Fitzgerald & Matthew Betts
The value of non-commodity ecosystem services provided by forests is widely recognized, but intensive forest management practices are increasing, with uncertain consequences for a multitude of these services. Quantitative relationships among biodiversity conservation, timber production, and other ecosystem services remain poorly understood, especially during the early successional period of intensively managed forestlands. We manipulated management intensity in regenerating forest plantations to test the prediction that treatments aimed at maximizing timber production decrease biodiversity conservation and...
