Effects of climate on bill morphology within and across Toxostoma thrashers

Charlotte Probst, Joel Ralston & Ian Bentley
Bird bills possess an important thermoregulatory function as they are a site for environmental heat exchange. Previous studies have demonstrated that birds in warmer climates have larger bills than those living in colder climates, as larger bills can dissipate more heat. Because this dry heat transfer does not incur water loss, it may be additionally advantageous in water-restricted habitats. Here, we examine the influence of climate on bill morphology in Toxostoma thrashers, a group of...

Key words related to public engagement with science by Society of Freshwater Science journals and conference sessions (1997-2019)

Ayesha S. Burdett, Katherine E. O’Reilly, Rebecca J. Bixby & Selena S. Connealy
Data set that was used to determine the frequency each of 4 key words (public engagement, education, outreach, or science communication) in the title or abstract of published papers in Freshwater Science (formerly the Journal of the North American Benthological Society) and oral presentations (talks) at the annual Society for Freshwater Science meetings from 1997 to 2019. Does not include any data on talks for 2013-2014 because they were not published during those years.

What does it mean to be wild? Assessing human influence on the environments of nonhuman primate specimens in museum collections

Andrea Eller, Stephanie Canington, Sana Saiyed, Rita Austin, Courtney Hofman & Sabrina Sholts
Natural history collections are often thought to represent environments in a pristine natural state, free from human intervention – the so-called “wild”. In this study, we aim to assess the level of human influence represented by natural history collections of wild-collected primates over 120 years at the Smithsonian Institution’s National Museum of Natural History (NMNH). Our sample consisted of 875 catarrhine primate specimens in NMNH collections, representing 13 genera collected in 39 countries from 1882...

Indoor dust as a matrix for surveillance of COVID-19 outbreaks

Nicole Renninger, Nick Nastasi, Ashleigh Bope, Samuel Cochran, Sarah Haines, Neeraja Balasubrahmaniam, Katelyn Stuart, Aaron Bivins, Kyle Bibby, Natalie Hull & Karen Dannemiller
Ongoing disease surveillance is a critical tool to mitigate viral outbreaks, especially during a pandemic. Environmental monitoring has significant promise even following widespread vaccination among high-risk populations. The goal of this work is to demonstrate molecular SARS-CoV-2 monitoring in bulk floor dust and related samples as a proof-of-concept of a non-invasive environmental surveillance methodology for COVID-19 and potentially other viral diseases. Surface swab, passive sampler, and bulk floor dust samples were collected from rooms of...

Effects of freshwater salinization and biotic stressors on amphibian morphology

Jacquelyn Lewis, Jonathan Borrelli, Devin Jones & Rick Relyea
Organisms are commonly exposed to numerous stressors that induce behavioral, physiological, or morphological changes in some combination. In northern temperate latitudes, de-icing agents are a major stressor to species in freshwater ecosystems (primarily sodium chloride; NaCl). Species-specific responses to road salt toxicity range from lethal to sublethal effects, but it remains unclear how these effects interact with biotic stressors. Morphology can be quite sensitive to environmental changes, yet we know little about how it is...

Social media and public perception as core aspect of public health: the cautionary case of @realdonaldtrump and COVID-19

Jeffrey Peterson & Agustin Fuentes
The social media milieu in which we are enmeshed has substantive impacts on our beliefs and perceptions. Recent work has established that this can play a role in influencing understanding of, and reactions to, public health information. Twitter, in particular, appears to play a substantive role in the public health information ecosystem. From July 25th, 2020 to November 15th, 2020, we collected weekly tweets related to COVID-19 keywords and assessed their networks, patterns and properties....

Data from: Divergent diapause life history timing drives both allochronic speciation and reticulate hybridization in an adaptive radiation of Rhagoletis flies

Meredith Doellman, Katherine Inskeep, Thomas Powell, Stewart Berlocher, Nicholas Seifert, Glen Hood, Gregory Ragland, Peter Meyers & Jeff Feder
Divergent adaptation to new ecological opportunities can be an important factor initiating speciation. However, as niches are filled during adaptive radiations, trait divergence driving reproductive isolation between sister taxa may also result in trait convergence with more distantly related taxa, increasing the potential for reticulated gene flow across the radiation. Here, we demonstrate such a scenario in a recent adaptive radiation of Rhagoletis fruit flies, specialized on different host plants. Throughout this radiation, shifts to...

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...

Inversions and genomic differentiation after secondary contact: when drift contributes to maintenance, not loss, of differentiation

Marina Rafajlovic, Jordi Rambla, Jeffrey L. Feder, Arcadi Navarro & Rui Faria
Due to their effects on reducing recombination, chromosomal inversions may play an important role in speciation by establishing and/or maintaining linked blocks of genes causing reproductive isolation (RI) between populations. This view fits empirical data indicating that inversions typically harbour loci involved in RI. However, previous computer simulations of infinite populations with 2-4 loci involved in RI implied that, even with gene flux as low as 10^(-8) per gamete, per generation between alternative arrangements, inversions...

Beyond leaf habit: generalities in plant function across 97 tropical dry forest tree species

German Vargas G., Tim J. Brodribb, Juan M. Dupuy, Roy González‐M., Catherine M. Hulshof, David Medvigy, Tristan A. P. Allerton, Camila Pizano, Beatriz Salgado‐Negret, Naomi B. Schwartz, Skip J. Van Bloem, Bonnie G. Waring & Jennifer S. Powers
Leaf habit has been hypothesized to define a linkage between the slow-fast plant economic spectrum and the drought resistance-avoidance trade-off in tropical forests (‘slow-safe versus fast-risky’). However, variation in hydraulic traits as a function of leaf habit has rarely been explored for a large number of species. We sampled leaf and branch functional traits of 97 tropical dry forest tree species from four sites to investigate whether patterns of trait variation varied consistently in relation...

Aboveground net primary productivity in regenerating seasonally dry tropical forest: contributions of rainfall, forest age, and soil

Justin Becknell, German Vargas, Daniel Pérez‐Aviles, David Medvigy & Jennifer Powers
Identifying factors controlling forest productivity is critical to understanding forest-climate change feedbacks, modeling vegetation dynamics, and carbon finance schemes. However, little research has focused on productivity in regenerating tropical forest which are expanding in their fraction of global area have an order of magnitude larger carbon uptake rates relative to older forest. We examined aboveground net primary productivity (ANPP) and its components (wood production and litterfall) over ten years in forest plots that vary in...

A reversal in sensory processing accompanies ongoing ecological divergence and speciation in Rhagoletis pomonella

Cheyenne Tait, Hinal Kharva, Marco Schubert, Daniel Kritsch, Andy Sombke, Jürgen Rybak, Jeffrey Feder & Shannon Olsson
Changes in behavior often drive rapid adaptive evolution and speciation. However, the mechanistic basis for behavioral shifts is largely unknown. The tephritid fruit fly Rhagoletis pomonella is an example of ecological specialization and speciation in action via a recent host plant shift from hawthorn to apple. These flies primarily utilize specific odors to locate fruit, and because they mate only on or near host fruit, changes in odor preference for apples versus hawthorns translate directly...

Glucocorticoid exposure predicts survival in female baboons

Fernando Campos, Elizabeth Archie, Laurence Gesquiere, Jenny Tung, Jeanne Altmann & Susan Alberts
Are differences in HPA axis activation across the adult lifespan linked to differences in survival? This question has been the subject of considerable debate. We analyze the link between survival and fecal glucocorticoid (GC) measures in a wild primate population, leveraging an unusually extensive longitudinal dataset of 14,173 GC measurements from 242 adult female baboons over 1,634 female-years. We document a powerful link between GCs and survival: females with relatively high current GCs or high...

Testing the potential contribution of Wolbachia to speciation when cytoplasmic incompatibility becomes associated with host‐related reproductive isolation

Daniel Bruzzese, Hannes Schuler, Thomas Wolfe, Mary Glover, Joseph Mastroni, Meredith Doellman, Cheyenne Tait, Wee Yee, Juan Rull, Martin Aluja, Glen Hood, Robert Goughnour, Christian Stauffer, Patrik Nosil, Jeffery Feder, Daniel J. Bruzzese, Thomas M. Wolfe, Mary M. Glover, Meredith M. Doellman, Wee L. Yee, Glen R. Hood & Jeffery L. Feder
Endosymbiont induced cytoplasmic incompatibility (CI) may play an important role in arthropod speciation. However, whether CI consistently becomes associated or coupled with other host-related forms of reproductive isolation (RI) to impede the transfer of endosymbionts between hybridizing populations and further the divergence process remains an open question. Here, we show varying degrees of pre- and post-mating RI exist among allopatric populations of two interbreeding cherry-infesting tephritid fruit flies (Rhagoletis cingulata and R. indifferens) across North...

Site-specific impacts of a major hurricane on alpha and beta diversity in tropical forest seedling communities

Samantha Worthy, Vanessa Rubio, Kirstin Staiger, Boris Ngouajio, Jie Yang & Nathan Swenson
Large scale disturbances are known to impact the alpha and beta diversity of communities. However, whether these disturbances increase or decrease diversity is often debated. The goal of this study was to quantify how the diversity of the seedling community was impacted within and across elevation in the El Yunque forest of Puerto Rico following a major hurricane. We tested two alternative hypotheses, that hurricanes are relatively more homogenizing or non-homogenizing forces, by quantifying changes...

Inhibitory control, exploration behaviour and manipulated ecological context are associated with foraging flexibility in the great tit

Jenny Coomes, Gabrielle Davidson, Michael Reichert, Ipek Kulahci, Camille Troisi & John Quinn
​​​​​Organisms are constantly under selection to respond effectively to diverse, sometimes rapid, changes in their environment, but not all individuals are equally plastic in their behaviour. Although cognitive processes and personality are expected to influence individual behavioural plasticity, the effects reported are highly inconsistent, which we hypothesise is because ecological context is usually not considered. We explored how one type of behavioural plasticity, foraging flexibility, was associated with inhibitory control (assayed using a detour-reaching task)...

Soil biogeochemistry across Central and South American tropical dry forests

Bonnie Waring, Mark De Guzman, Dan Du, Juan Dupuy, Maga Gei, Jessica Gutknecht, Catherine Hulshof, Nicolas Jelinski, Andrew Margenot, David Medvigy, Camila Pizano, Beatriz Salgado-Negret, Naomi Schwartz, Annette Trierweiler, Skip Van Bloem, German Vargas G & Jennifer Powers
The availability of nitrogen (N) and phosphorus (P) controls the flow of carbon (C) among plants, soils, and the atmosphere, thereby shaping terrestrial ecosystem responses to global change. Soil C, N, and P cycles are linked by drivers operating at multiple spatial and temporal scales: landscape-level variation in macroclimate, seasonality, and soil geochemistry; stand-scale heterogeneity in forest composition and structure; and microbial community dynamics at the soil pore scale. Yet in many biomes, we do...
