Risk factors for third-generation cephalosporin-resistant and extended-spectrum β-lactamase-producing Escherichia coli carriage in domestic animals of semirural parishes east of Quito, Ecuador

Siena Mitman
Extended-spectrum β-lactamase (ESBL)-producing and other antimicrobial resistant (AR) Escherichia coli threaten human and animal health worldwide. This study examined risk factors for domestic animal colonization with ceftriaxone-resistant (CR) and ESBL-producing E. coli in semirural parishes east of Quito, Ecuador, where small-scale food animal production is common. Survey data regarding household characteristics, animal care, and antimicrobial use were collected from 304 households over three sampling cycles, and 1195 environmental animal fecal samples were assessed for E....

Supporting data for: Estimate of OH trends over one decade in North American cities

Qindan Zhu, Josh Laughner & Ron Cohen
The hydroxyl radical (OH) is the most important oxidant on global and local scales in the troposphere. Urban OH controls the removal rate of primary pollutants and triggers the production of ozone. Interannual trends of OH in urban areas are not well documented or understood due to the short lifetime and high spatial heterogeneity of OH. We utilize machine learning with observational inputs emphasizing satellite remote sensing observations to predict surface OH in 49 North...

Fossilized pollen malformations as indicators of past environmental stress and meiotic disruption: insights from modern conifers

Jeffrey Benca, Ivo Duijnstee & Cindy Looy
Pollen malformations have been proposed as a paleoenvironmental stress proxy. However, the frequency and variability of pollen malformations under near-optimal conditions and environmental stress, as well as their developmental origins, remain unclear. To bridge these gaps, we compared pollen malformation frequencies and assemblages of 14 extant conifer genera of Pinaceae and Podocarpaceae producing saccate (winged) grains grown under near-optimal conditions. These baseline pollen yields were compared with those produced by Pinus mugo ‘Columnaris’ cultured under...

Dietary ethanol ingestion by free-ranging spider monkeys (Ateles geoffroyi)

Christina Campbell, Aleksey Maro, Victoria Weaver & Robert Dudley
Ethanol within ripe and over-ripe fruit is produced naturally through the metabolic activity of fermentative yeasts. As a consequence, frugivorous animals may chronically consume ethanol as part of their routine diet, although direct measurements of such exposure are lacking. Here, we present data on ethanol concentrations within fruits of the Neotropical tree Spondias mombin (Anacardiaceae) that are eaten by Geoffroy's spider monkeys (Ateles geoffroyi) on Barro Colorado Island, Panama. Of collected fruits that were partially...

Taxonomy based on limited genomic markers may underestimates species diversity of rockhopper penguins and threaten their conservation

María José Frugone, Theresa Cole, María Eugenia López, Gemma Clucas, Pável Matos-Maraví, Nicolás Lois, Pierre Pistorius, Francesco Bonadonna, Phil Trathan, Andrea Polanowski, Barbara Wienecke, Andrea Raya-Rey, Klemens Pütz, Antje Steinfurth, Ke Bi, Cynthia Wang-Claypool, Rauri C. K. Bowie, Jonathan Waters, Elie Poulin & Juliana Vianna
Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures and evolutionary histories. Reliance on limited numbers of genetic markers that may be underpowered can make species delimitation even more challenging, potentially resulting in taxonomic inconsistencies. Rockhopper penguins of the genus Eudyptes comprise three broadly recognized taxa: northern (E. moseleyi), southern (E. chrysocome), and eastern rockhopper (E....

Sofia Medina Ruiz, Caroline Albertin, Therese Mitros, Hannah Schmidbaur, Gustavo Sanchez, Z.Y. Wang, Jane Grimwood, Joshua Rosenthal, Clifton Ragsdale, Oleg Simakov & Daniel Rokhsar
Cephalopods are known for their large nervous systems, complex behaviors and morphological innovations. To investigate the genomic underpinnings of these features, we assembled the chromosomes of the Boston market squid Doryteuthis (Loligo) pealeii and the California two-spot octopus, Octopus bimaculoides, and compared them with those of the Hawaiian bobtail squid, Euprymna scolopes. The genomes of the soft-bodied (coleoid) cephalopods are highly rearranged relative to other extant molluscs, indicating an intense, early burst of genome restructuring....

Data from: We get by with a little help from our friends: shared adaptive variation provides a bridge to novel ecological specialists during adaptive radiation

Emilie Richards & Christopher Martin
Adaptive radiations involve astounding bursts of phenotypic, ecological, and species diversity. However, the microevolutionary processes that underlie the origins of these bursts are still poorly understood. We report the discovery of an intermediate ‘wide-mouth’ scale-eating ecomorph in a sympatric radiation of Cyprinodon pupfishes, illuminating the transition from a widespread algae-eating generalist to a novel microendemic scale-eating specialist. We first show that this ecomorph occurs in sympatry with generalist C. variegatus and scale-eating specialist C. desquamator...

Phylogeny of species, infraspecific taxa, and forms in subgenus Xiphium (Iris: Iridaceae) that have centers of diversity in the Mediterranean Basin biodiversity hotspot

Carol Wilson, Zoe Boosalis, Michael Sandor, Manuel Crespo & Mario Martinez-Azorin
Iris subgenus Xiphium is a small group of taxa that mostly occur in the Mediterranean Basin, a long-recognized biodiversity hotspot. Phylogenetic relationships among these Iris were reconstructed based on sequence data from 110 nuclear markers and whole plastomes using Bayesian inference and maximum likelihood methods. Best trees based on plastome and combined datasets resolved subgenus Xiphium and I. xiphium as not monophyletic while nuclear data resolved the subgenus as monophyletic but I. xiphium as not...

Rebecca Ostertag, Carla Restrepo, Iveren Abeim, Roxana Aragón, Michelle Ataroff, Hazel Chapman, Belen Fadrique, Grizelle González, Achim Häger, Jürgen Homeier, Luis Daniel Llambí, Rikke Reese Næsborg, Laura Nohemy Poma López, Jorge Andrés Ramirez Correa, Klara Scharnagl, Conrado Tobón, James W. Dalling, Patrick H. Martin, Iveren Abiem, Shin‐Ichiro Aiba, Esteban Alvarez‐Dávila, Augusta Y. Cueva‐Agila, Romina D. Fernández, Sybil G. Gotsch, Carlos Iñiguez‐Armijos … & Cameron B. Williams
The “hierarchy of factors” hypothesis states that decomposition rates are controlled primarily by climatic, followed by biological and soil variables. Tropical montane forests (TMF) are globally important ecosystems, yet there have been limited efforts to provide a biome-scale characterization of litter decomposition. We designed a common litter decomposition experiment replicated in 23 tropical montane sites across the Americas, Asia, and Africa and combined these results with a previous study of 23 sites in tropical lowland...

Food webs for three burn severities after wildfire in the Eldorado National Forest, California

John McLaughlin, John Schroeder, Angela White, Kate Culhane, Haley Mirts, Gina Tarbill, Laura Sire, Matt Page, Elijah Baker, Max Moritz, Justin Brasheres, Hillary Young & Rahel Sollmann
We provide data on ecological community responses to wildfire, collected three years post-fire, across three burn conditions (unburned, moderate severity and high severity) in the Eldorado National Forest, California. The data were collected with 19 sampling methods deployed across 27 sites (nine in each burn condition) used to estimate richness, body size, abundance and biomass density for 849 species (including 107 primary producers, 634 invertebrates, 94 vertebrates). The sampling methods are detailed in a companion...

The eco-evolutionary history of Madagascar presents unique challenges to tropical forest restoration

Katherine A. Culbertson, Timothy L.H. Treuer, Ariadna Mondragon Botero, Tanjona Ramiadantsoa & J. Leighton Reid
High biodiversity and endemism combined with persistently high deforestation rates mark Madagascar as one of the hottest of biodiversity hotspots. Contemporary rising interest in large-scale reforestation, both globally and throughout Madagascar itself, presents a promising impetus for forest restoration and biodiversity conservation across the island. However, Madagascar may face unique restoration challenges due to its equally unique eco-evolutionary trajectory, which must be understood to enable successful ecological restoration. We conducted a systematic review of potential...

Data from: Land use change through the lens of macroecology: insights from Azorean arthropods and the Maximum Entropy Theory of Ecology

Micah Brush, Tom Matthews, Paulo Borges & John Harte
Abstract from Brush et al. (2022) Ecography: Human activity and land management practices, in particular land use change, have resulted in the global loss of biodiversity. These types of disturbance affect the shape of macroecological patterns, and therefore analyzing these patterns can provide insights into how ecosystems are affected by land use change. We here use arthropod census data from 96 sites at Terceira Island in the Azores archipelago across four different land uses of...

Aposematic patterns shift continuously through the life of poison frogs

Michael Yuan, Catherine Jung, Rayna Bell & Jessica Nelson
Color and pattern are often dynamic traits that change throughout an individual’s lifetime. Still, long-term shifts in coloration have received limited attention. Dendrobatid poison frogs are a classical system in the study of color and pattern evolution in which both sexual selection and predation avoidance are thought to drive the evolution of color and pattern at the population and species level. Here, we highlight an overlooked axis of pattern diversity, within individual variation, using three...

Transposable element accumulation drives size differences among polymorphic Y chromosomes in Drosophila

Alison Nguyen
Y chromosomes of many species are gene poor and show low levels of nucleotide variation, yet often display high amounts of structural diversity. Dobzhansky cataloged several morphologically distinct Y chromosomes in Drosophila pseudoobscura that differ in size and shape, but the molecular causes of their dramatic size differences are unclear. Here we use cytogenetics and long-read sequencing to study the sequence content of polymorphic Y chromosomes in D. pseudoobscura. We show that Y chromosomes differ...

Excitatory neurotransmission activates compartmentalized calcium transients in Müller glia without affecting lateral process motility

Joshua Tworig, Chandler Coate & Marla Feller
Neural activity has been implicated in the motility and outgrowth of glial cell processes throughout the central nervous system. Here we explore this phenomenon in Müller glia, which are specialized radial astroglia that are the predominant glial type of the vertebrate retina. Müller glia extend fine filopodia-like processes into retinal synaptic layers, in similar fashion to brain astrocytes and radial glia which exhibit perisynaptic processes. Using two-photon volumetric imaging, we found that during the second...

Habitat fragmentation disrupts reestablishment mechanisms and post-drying community recovery in an intermittent stream

Robert Fournier
Biota in disturbance-prone landscapes have evolved a variety of strategies for long-term population persistence, via local endurance (resistance) and regional recolonization (resilience). Habitat fragmentation could affect both viability of resistance forms and availability of recolonization pathways—thus altering post-disturbance community reestablishment. Here, we studied a pristine intermittent stream (Chalone Creek, California) to understand how fragmentation may alter post-disturbance recolonization. We monitored benthic invertebrate reestablishment during the rewetting phase along a ~2-km gradient of fragmentation (i.e., distance...

Interactive effects of multiscale diversification practices on farmland bird stress

Elissa Olimpi, Hallie Daly, Karina Garcia, Victoria Glynn, David Gonthier, Claire Kremen & Leithen M'Gonigle
Farmland diversification practices (i.e., methods used to produce food sustainably by enhancing biodiversity in cropping systems) are sometimes considered beneficial to both agriculture and biodiversity, but most studies of these practices rely on species richness, diversity, or abundance as a proxy for habitat quality. Biodiversity assessments may miss early clues that populations are imperiled when species presence does not imply persistence. Physiological stress indicators may help identify low-quality habitats before population declines occur. We explored...

Cricket thermal preferences and starvation

Lisa Treidel, Christopher Huebner, Kevin Roberts & Caroline Williams
Insects behaviorally thermoregulate across the diel cycle and their preferred microhabitats change based on current resource availabilities and the thermal performance optima of traits. Specific combinations of traits being prioritized are set by life history strategies, making life history an important intrinsic determinant of thermal preferences. However, we do not know how life history strategies shape plasticity of behavioral thermoregulation, limiting our ability to predict responses to environmental variability. We compared female variable field crickets...

Semi‐quantitative metabarcoding reveals how climate shapes arthropod community assembly along elevation gradients on Hawaii Island

Jun Ying Lim, Jairo Patiño, Suzuki Noriyuki, Henrik Krehenwinkel, Luis Simmari, Rosemary Gillespie, Luis Cayetano & Rosemary G. Gillespie
Spatial variation in climatic conditions along elevation gradients provides an important backdrop by which communities assemble and diversify. Lowland habitats tend to be connected through time, whereas highlands can be continuously or periodically isolated, conditions that have been hypothesized to promote high levels of species endemism. This tendency is expected to be accentuated among taxa that show niche conservatism within a given climatic envelope. While species distribution modeling approaches have allowed extensive exploration of niche...

Effects of supplemental feeding on nesting success and physiological metrics in Eastern Bluebirds (Sialia sialis)

Danielle Perryman, Meelyn Pandit, Eric Riddell, Tiana Sanders, Ian Kanda & Jennifer Grindstaff
Supplemental feeding is a common anthropogenic influence on wildlife which, dependent on natural food availability, can have positive or negative effects on physiological condition. Animals may respond negatively to supplemental feeding if the artificial food source increases disease risk due to aggregation. We manipulated supplemental food availability in a wild population of Eastern bluebirds, Sialia sialis, to examine the influence on physiological metrics and nesting success without causing birds to aggregate to access food. Adult...

Karuk ecological fire management practices promote elk habitat in Northern California

Thomas Connor, Emilio Tripp, William Tripp, B. J. Saxon, Jessica Camarena, Asa Donahue, Daniel Sarna, Luke Macaulay, Tim Bean, Adam Hanbury-Brown & Justin Brashares
After a century of fire suppression and accumulating fuel loads in North American forests, prescribed burns are increasingly used to prevent conditions leading to catastrophic megafire. There is widespread evidence that prescribed fire was used by Indigenous communities to manage natural and cultural resources tribes for thousands of years. Wildlife habitat is an example of an ecological response that was actively managed with prescribed burns by Indigenous American peoples and is an important factor in...
