Aedes aegypti in North America (Microsatellite and SNP array)

Evlyn Pless, Andrea Gloria-Soria & Jeffrey Powell
The Aedes aegypti mosquito first invaded the Americas about 500 years ago and today is a widely distributed invasive species and the primary vector for viruses causing dengue, chikungunya, Zika, and yellow fever. Here we test the hypothesis that the North American colonization by Ae. aegypti occurred via a series of founder events. We present findings on genetic diversity, structure, and demographic history using data from 70 Ae. aegypti populations in North America genotyped at...

Photographs of 15-day wound closure progress in C57BL/6J mice

Hsin-Ya Yang, Michelle Bagood, Hector Carrion & Rivkah Isseroff
Evaluating and tracking wound size is a fundamental metric for the wound assessment process. Good location and size estimates can enable proper diagnosis and effective treatment. Traditionally, laboratory wound healing studies include a collection of images at uniform time intervals exhibiting the wounded area and the healing process in the test animal, often a mouse. These images are then manually observed to determine key metrics —such as wound size progress— relevant to the study. However,...

Phylogenomic resolution of the root of Panpulmonata, a hyperdiverse radiation of gastropods: new insight into the evolution of air breathing

Patrick Krug, Serena Caplins, Krisha Algoso, Kanique Thomas, Angel Valdes, Rachael Wade, Nur Leena Wong, Douglas Eernisse & Kevin Kocot
Transitions to terrestriality have been associated with major animal radiations including land snails and slugs in Stylommatophora (>20,000 described species), the most successful lineage of ‘pulmonates’ (a non-monophyletic assemblage of air-breathing gastropods). However, phylogenomic studies have failed to robustly resolve relationships among traditional pulmonates and affiliated marine lineages that comprise clade Panpulmonata (Mollusca, Gastropoda), especially two key taxa: Sacoglossa, a group including photosynthetic sea slugs; and Siphonarioidea, intertidal limpet-like snails with a non-contractile pneumostome (narrow...

Conference scheduling undermines diversity efforts

Nicholas Burnett, Emily King, Mary Salcedo, Richelle Tanner & Kathryn Wilsterman
Scientific conferences incorporate diversity-focused events into their programming to increase their diversity and inclusivity and to improve the conference experience for scientists from underrepresented groups (URGs). While simply adding diversity-focused events to conferences is positive, maximizing their impact requires that conferences organizeand schedule these events to minimize well-acknowledged, problematic patterns such as the minority tax. To our knowledge, the programming of diversity-focused events at conferences has not been systematically reviewed to identify the extent of...

Flower plantings support wild bee reproduction and may also mitigate pesticide exposure effects

, Clara Stuligross, Arvid Lindh, Rosemary Malfi, Katherine Burns, John Mola, Staci Cibotti & Neal Williams
1. Sustainable agriculture relies on pollinators, and wild bees benefit yield of multiple crops. However, the combined exposure to pesticides and loss of flower resources, driven by agricultural intensification, contribute to declining diversity and abundance of many bee taxa. Flower plantings along the margins of agricultural fields offer diverse food resources not directly treated with pesticides. 2. To investigate the potential of flower plantings to mitigate bee pesticide exposure effects and support bee reproduction, we...

Next-generation phylogeography resolves post-glacial colonization patterns in a widespread carnivore, the red fox (Vulpes vulpes), in Europe

Allan McDevitt, Ilaria Coscia, Samuel S Browett, Aritz Ruiz-Gonzalez, Mark Statham, Inka Ruczynska, Liam Roberts, Joanna Stojak, Alain Frantz, Karin Norén, Erik Agren, Jane Learmount, Mafalda Basto, Carlos Fernandes, Peter Stuart, David G Tosh, Magda Sindicic, Tibor Andreanszky, Marja Isomursu, Marek Panek, Andrey Korolev, Innokentiy M Okhlopkov, Alexander P Saveljev, Bostjan Pokorny, Katarina Flajsman … & Jan Wójcik
Carnivores tend to exhibit a lack of (or less pronounced) genetic structure at continental scales in both a geographic and temporal sense using various mitochondrial DNA markers on modern and/or ancient specimens. This tends to confound the identification of refugial areas and post-glacial colonization patterns in this group. In this study we used Genotyping-by-Sequencing (GBS) to reconstruct the phylogeographic history of a widespread carnivore, the red fox (Vulpes vulpes), in Europe by investigating broad-scale patterns...

Different factors limit early- and late-season windows of opportunity for monarch development

Louie Yang, Karen Swan, Eric Bastin, Jessica Aguilar, Meredith Cenzer, Andrew Codd, Natalie Gonzalez, Tracie Hayes, August Higgins, Xang Lor, Chido Macharaga, Marshall McMunn, Kenya Oto, Nicholas Winarto, Darren Wong, Tabatha Yang, Numan Afridi, Sarah Aguilar, Amelia Allison, Arden Ambrose-Winters, Edwin Amescua, Mattias Apse, Nancy Avoce, Kirstin Bastin, Emily Bolander … & Yichao Zeng
Seasonal windows of opportunity are intervals within a year that provide improved prospects for growth, survival, or reproduction. However, few studies have sufficient temporal resolution to examine how multiple factors combine to constrain the seasonal timing and extent of developmental opportunities. Here, we document seasonal changes in milkweed (Ascelpias fascicularis) – monarch (Danaus plexippus) interactions with high-resolution throughout the last three breeding seasons prior to a precipitous single-year decline in the western monarch population. Our...

United States recycled content standards for lithium-ion batteries

Jessica Dunn, Alissa Kendall & Slattery Margarett
Lithium-ion battery recycling can decrease life cycle environmental impacts of electric vehicles (EVs) and assist in securing domestic supply chains. However, the US, the third largest market for EVs, has no policies for recycling of batteries at their end-of-life. The European Union has proposed recycled content standards (RCSs) to help drive a circular battery ecosystem. This analysis calculates feasible RCSs for the US based on future sale projections, techno-economic assessment, life cycle assessment, and material...

Data for: Socio-economic and environmental life cycle assessment of complete streets

Maryam Ostovar, Ali Azhar Butt, John Harvey & Zachary Ramalingam
“Complete streets” is a design concept for primarily urban streets and intersections (existing and/or new) intended to encourage active transportation by bicyclists and pedestrians by making streets safer, convenient, and attractive for active transportation; motorized transportation and parking are also accommodated in the design concept. The social and economic performance indicators included in the social LCA (SLCA) framework that was used in this project provide a great deal of insight into specific and different potential...

Did extreme nest predation favor the evolution of obligate brood parasitism in a duck?

Bruce Lyon, Alejandra Carminati, Geneviève Goggin & John Eadie
Obligate brood parasites depend entirely on other species to raise their offspring. Most avian obligate brood parasites have altricial offspring that require enormous amounts of post-hatching parental care, and the large fecundity boost that comes with complete emancipation from parental care likely played a role in the independent evolution of obligate parasitism in several altricial lineages. The evolution of obligate parasitism in the black-headed duck, however, is puzzling because its self-feeding precocial offspring should not...

Behavioural correlations across multiple stages of the antipredator response: do animals that escape sooner hide longer?

Chelsea Ortiz-Jimenez, Marcus Michelangeli, Erika Pendleton, Andrew Sih & Jennifer Smith
A fundamental assumption in predator–prey ecology is that prey responses comprise two main stages: escape when attack occurs or appears imminent and avoid the threat by seeking refuge until it has passed. While numerous studies have examined either initial prey responses to an approaching predator (flight initiation distance, FID), or subsequent hiding behaviour (e.g. latency to resume activity), to our knowledge, no previous studies have repeatedly tested multiple individuals in nature to quantify whether initial...

Local adaptation in a marine foundation species: implications for resilience to future global change

Katherine DuBois & John Stachowicz
Environmental change is multidimensional, with local anthropogenic stressors and global climate change interacting to differentially impact populations throughout a species’ geographic range. Within species, the spatial distribution of phenotypic variation and its causes (i.e. local adaptation or plasticity) will determine species’ adaptive capacity to respond to a changing environment. However, comparatively little is known about the spatial scale of adaptive differentiation among populations and how these patterns of local adaptation might drive vulnerability to global...

Demographic data collection in STEM organizations

Nicholas Burnett, Alyssa Hernandez, Emily King, Richelle Tanner & Kathryn Wilsterman
Professional organizations in STEM (science, technology, engineering, and mathematics) can use demographic data to quantify recruitment and retention (R&R) of underrepresented groups within their memberships. However, variation in the types of demographic data collected can influence the targeting and perceived impacts of R&R efforts - e.g., giving false signals of R&R for some groups. We obtained demographic surveys from 73 U.S.-affiliated STEM organizations, collectively representing 712,000 members and conference-attendees. We found large differences in the...

This includes surveys before bike share existing in the...

Biodiversity and infrastructure interact to drive tourism to and within Costa Rica

Alejandra Echeverri, Jeffrey R. Smith, Dylan MacArthur-Waltz, Katherine S. Lauck, Christopher B. Anderson, Rafael Monge Vargas, Irene Alvarado Quesada, Spencer A. Wood, Rebecca Chaplin-Kramer & Gretchen C. Daily
Significance Tourism accounts for roughly 10% of global gross domestic product, with nature-based tourism its fastest-growing sector in the past 10 years. Nature-based tourism can theoretically contribute to local and sustainable development by creating attractive livelihoods that support biodiversity conservation, but whether tourists prefer to visit more biodiverse destinations is poorly understood. We examine this question in Costa Rica and find that more biodiverse places tend indeed to attract more tourists, especially where there is...

Conifer forest plant species composition across nine years following a high severity fire

JonahMaria Weeks
Ecological disturbance regimes across the globe are being altered via direct and indirect human influences. Biodiversity loss at multiple scales can be a direct outcome of these shifts. Fire, especially in dry forests, is an ecological disturbance that is experiencing dramatic changes due to climate change, fire suppression, increased human population in fire-prone areas, and alterations to vegetation composition and structure. Dry western conifer forests that historically experienced frequent, low severity fires are now increasingly...

The gut microbiome variability of a butterflyfish increases on severely degraded Caribbean reefs

Friederike Clever, Jade M. Sourisse, Richard F. Preziosi, Jonathan A. Eisen, E. Catalina Rodriguez-Guerra, Jarrod J. Scott, Laetitia G.E. Wilkins, Andrew H. Altieri, W. Owen McMillan & Matthieu Leray
Environmental degradation has the potential to alter key mutualisms that underlie the structure and function of ecological communities. How microbial communities associated with fishes vary across populations and in relation to habitat characteristics remains largely unknown despite their fundamental roles in host nutrition and immunity. We find significant differences in the gut microbiome composition of a facultative coral-feeding butterflyfish (Chaetodon capistratus) across Caribbean reefs that differ markedly in live coral cover (∼0–30%). Fish gut microbiomes...

Sulfate radical from irradiated aqueous sulfate solutions

Tran Nguyen
The sulfate anion radical (SO4• –) is known to be formed in the autoxidation chain of sulfur dioxide, and from minor reactions when sulfate or bisulfate ions are activated by OH radicals, NO3 radicals, or iron. Here we report a new source of SO4• –, from the irradiation of the liquid water of sulfate-containing organic aerosol particles under natural sunlight and laboratory ultraviolet radiation. Irradiation of aqueous sulfate mixed with a variety of atmospherically relevant...

How community forest management performs when REDD+ payments fail

Amy Collins, Mark Grote, Tim Caro, Aniruddha Ghosh, James Thorne, Jonathan Salerno & Monique Borgerhoff Mulder
The reduced emissions in deforestation and degradation (REDD+) initiative uses payments for ecosystem services as incentives for developing countries to manage and protect their forests. REDD+ initiatives also prioritize social (and environmental) co-benefits aimed at improving the livelihoods of communities that are dependent on forests. Despite the incorporation of co-benefits into REDD+ goals, carbon sequestration remains the primary metric for which countries can receive payments from REDD+, but after more than 10 years of REDD+,...

Results of survey for selected parasites in Alaska brown bears (Ursus arctos)

Ellen Haynes, Sarah Coker, Michael Yabsley, Kevin Niedrighaus, Andrew Ramey, Guilherme Verocai, Grant Hilderbrand, Kyle Joly, David Gustine, Buck Mangipane, William Leacock, Anthony Crupi & Christopher Cleveland
To assess the prevalence of endo- and ectoparasites in Alaska brown bears (Ursus arctos), blood and fecal samples were collected during 2013 – 2016 from five locations: Gates of the Arctic National Park and Preserve (GAAR), Katmai National Park (KATM), Lake Clark National Park and Preserve (LACL), Yakutat Forelands (YAK), and Kodiak Island (KOD). Standard fecal centrifugal-flotation was used to screen for gastrointestinal parasites, molecular techniques were used to test blood for the presence of...

Leveraging spatial patterns in precipitation forecasts using deep learning to support risk-averse flood management

Chen Zhang, Zachary Brodeur, Scott Steinschneider & Jonathan Herman
Short-term forecasts of heavy precipitation are critical to regional flood control operations, particularly in the Western U.S. where atmospheric rivers can be predicted reliably days in advance. However, spatial error in these forecasts may reduce their utility for risk-averse system operations, where false negatives could be especially costly. Here we investigate whether deep learning methods can leverage spatial patterns in precipitation forecasts to (1) improve the skill of predicting the occurrence of heavy precipitation events...

The biogeography of community assembly: latitude and predation drive variation in community trait distribution in a guild of epifaunal crustaceans

Collin Gross, Collin Gross, J Duffy, Kevin Hovel, Melissa Kardish, Pamela Reynolds, Christoffer Boström, Katharyn Boyer, Mathiew Cusson, Johan Eklöf, Aschwin Engelen, Klemens Eriksson, Joel Fodrie, John Griffin, Clara Hereu, Masakazu Hori, A Randall Hughes, Mikhail Ivanov, Pablo Jorgensen, Claudia Kruschel, Kun-Seop Lee, Jonathan Lefcheck, Karen McGlathery, Per-Olav Moksnes, Masahiro Nakaoka … & Jay Stachowicz
While considerable evidence exists of biogeographic patterns in the intensity of species interactions, the influence of these patterns on variation in community structure is less clear. Using a model selection approach on measures of trait dispersion in crustaceans associated with eelgrass (Zostera marina) spanning 30º of latitude in two oceans, we found that dispersion strongly increased with increasing predation and decreasing latitude. Ocean and epiphyte load appeared as secondary predictors; Pacific communities were more overdispersed...

Low-pH seawater alters indirect interactions in rocky-shore tidepools

Brittany Jellison, Brian Gaylord, Aaron Ninokawa, Kristen Elsmore, Gabriel Ng, Jeffrey Miller & Tessa Hill
Ocean acidification is expected to degrade marine ecosystems, yet most studies focus on organismal-level impacts rather than ecological perturbations. Field studies are especially sparse, particularly ones examining shifts in direct and indirect consumer interactions. Here we address such connections within tidepool communities of rocky shores, focusing on a three-level food web involving the keystone sea star predator, Pisaster ochraceus, a common herbivorous snail, Tegula funebralis, and a macroalgal basal resource, Macrocystis pyrifera. We demonstrate that...

Influence of crop field size on pest densities, pesticide use, and crop yield

Jay Rosenheim
Increasing diversity on farms can enhance many key ecosystem services to and from agriculture, and natural control of arthropod pests is often presumed to be among them. The expectation that increasing the size of monocultural crop plantings exacerbates the impact of pests is common throughout the agroecological literature. Here, we share five data sets, describing 14 pest species, 5 crops (cotton in California, citrus in California, potatoes in Peru, grapes in Spain, and olives in...
