Photodegradation of plant litter cuticles enhances microbial decomposition by increasing uptake of non-rainfall moisture

J. Robert Logan, Paul Barnes & Sarah Evans
Litter decomposition plays a central role in carbon cycling in terrestrial ecosystems worldwide. In drylands, which cover 40% of the Earth’s land surface, photodegradation and biotic decomposition driven by non-rainfall moisture are important mechanisms of litter decay, though studies have only recently begun examining interactions between these two processes. We describe a novel priming mechanism in which photodegradation and biotic decay of the cuticle of plant litter increases litter absorption of non-rainfall moisture (fog, dew,...

Stronger niche than dispersal effects on α- and β-diversity of stream algae, insects, and fish across latitudes in the US

Joseph Mruzek, William Budnick, Chad Larson, Dinh Luc & Sophia Passy
Aim: Niche and dispersal processes influence biodiversity, but their relative importance along latitude is unclear. We predicted that: i) niche processes would dominate at high latitudes due to increased climatic stress, consistent with the physiological tolerance hypothesis and the Dobzhansky-MacArthur hypothesis and ii) dispersal limitation would prevail at low latitudes due to narrower niches and smaller range sizes, as postulated by the dispersal-ecological specialization tradeoff hypothesis, the latitude-niche breadth hypothesis, and Rapoport’s rule. Location: Central...

Data for: Local adaptation of seed and seedling traits along a natural aridity gradient may both predict and constrain adaptive responses to climate change

Kyle Christie, Natalie Pierson, David Lowry & Liza Holeski
Local adaptation of seed and seedling traits along a natural aridity gradient may both predict and constrain adaptive responses to climate change (American Journal of Botany 2022) Premise of study: Variation in seed and seedling traits underlies how plants interact with their environment during establishment, a crucial life history stage. We quantified genetic-based variation in seed and seedling traits in populations of the annual plant Plantago patagonica across a natural aridity gradient, leveraging natural intraspecific...

Linked networks reveal dual roles of insect dispersal and species sorting for bacterial communities in flowers

Ash Zemenick, Rachel Vannette & Jay Rosenheim
Due to the difficulty of tracking microbial dispersal, it is rarely possible to disentangle the relative importance of dispersal and species sorting for microbial community assembly. Here, we leverage a detailed multilevel network to examine drivers of bacterial community assembly within flowers. We observed flower visitors to 20 focal plant species in a coflowering community in the Sierra Nevada, revealing 289 species of arthropods. We also analyzed bacterial communities on flowers of each species. We...

Data from: Context-dependent effects of shifting large herbivore assemblages on plant structure and diversity

Devyn Orr, An Bui, Maggie Klope, Michelle Lee, Ian McCullough, Carina Motta, Isabella Mayorga, Kelli Konicek & Hillary Young
Despite wide recognition of the importance of anthropogenically driven changes in large herbivore communities – including both declines in wildlife and increases in livestock – there remain large gaps in our knowledge about the impacts of these changes on plant communities, particularly when combined with concurrent changes in climate. Considering these prominent forms of global change in tandem enables us to better understand controls on savanna vegetation structure and diversity under real-world conditions.We conducted a...

Ungulate herbivores as drivers of Aspen recruitment and understory composition throughout arid Montane landscapes

J. Hall Cushman, Elizabeth Reikowski & Tyler Refsland
Herbivory by wild and domestic ungulates can influence tree recruitment and understory forest communities throughout the world. Herbivore-driven declines in tree recruitment have been observed for quaking aspen (Populus tremuloides), a foundation species whose health and management is recognized as a critical priority throughout much of its range. Livestock fencing is commonly used to promote aspen regeneration, but its effectiveness is rarely assessed, especially across large spatial scales. Using a livestock-reduction experiment, we evaluated the...

Literature review dataset on predation-risk effects

Scott Peacor, David Kimbro, Nathan Dorn, Justine Smith, Michael Sheriff & Michael Cherry
A well-accepted narrative in ecology is that prey modify traits to reduce predation risk, and the trait modification has costs large enough to cause ensuing demographic, trophic and ecosystem consequences, with implications for conservation, management, and agriculture. But ecology has a long history of emphasizing that quantifying the importance of an ecological process ultimately requires evidence linking a process to unmanipulated field patterns. We suspected that such process-linked-to pattern (PLP) studies were poorly represented in...

Data from: Previous inter-sexual aggression increases female mating propensity in fruit flies

David Filice & Reuven Dukas
Female mate choice is a complex decision making process that involves many context-dependent factors. Understanding the factors that shape variation in female mate choice has important consequences for evolution via sexual selection. In many animals including fruit flies, Drosophila melanogaster, males often use aggressive mating strategies to coerce females into mating, but it is not clear if females’ experience with sexual aggression shapes their future behaviors. Here, we used males derived from lineages that were...

Dataset from: Changes in cell size and shape during 50,000 generations of experimental evolution with Escherichia coli

Nkrumah Grant, Ali Abdel Magid, Joshua Franklin, Yann Dufour & Richard Lenski
Bacteria adopt a wide variety of sizes and shapes, with many species exhibiting stereotypical morphologies. How morphology changes, and over what timescales, is less clear. Previous work examining cell morphology in an experiment with Escherichia coli showed that populations evolved larger cells and, in some cases, cells that were less rod-like. That experiment has now run for over two more decades. Meanwhile, genome sequence data are available for these populations, and new computational methods enable...

Increases in vein length compensate for leaf area lost to lobing in grapevine

Zoë Migicovsky, Joel F. Swift, Zachary Helget, Laura L. Klein, Anh Ly, Matthew Maimaitiyiming, Karoline Woodhouse, Anne Fennell, Misha Kwasniewski, Allison J. Miller, Peter Cousins & Daniel H. Chitwood
There is considerable variation in leaf lobing and leaf size, including among grapevines, some of the most well-studied leaves. We examined the relationship between leaf lobing and leaf size across grapevine populations which varied in extent of leaf lobing. We used homologous landmarking techniques to measure 2,632 leaves across two years in 476 unique, genetically distinct grapevines from 5 biparental crosses which vary primarily in the extent of lobing. We determined to what extent leaf...

Diverse aging rates in ectothermic tetrapods provide insights for the evolution of aging and longevity

Beth Reinke, Anne Bronikowski & David Miller
Comparative studies of mortality in the wild are necessary to understand the evolution of aging, yet ectothermic tetrapods are under-represented in this comparative landscape despite their suitability for testing evolutionary hypotheses. We present a study of aging rates and longevity across wild tetrapod ectotherms, utilizing data from 107 populations (77 species) of non-avian reptiles and amphibians. We test hypotheses of how thermoregulatory mode, temperature, protective phenotypes, and pace of life history contribute to demographic aging....

Reproductive benefits associated with dispersal in headwater populations of Trinidadian guppies (Poecilia reticulata)

Isabela Lima Borges, Jillian Dangerfield, Lisa Angeloni, Chris Funk & Sarah Fitzpatrick
Theory suggests that the evolution of dispersal is balanced by its fitness costs and benefits, yet empirical evidence is sparse due to the difficulties of measuring dispersal and fitness in natural populations. Here, we use spatially-explicit data from a multi-generational capture-mark-recapture study of two populations of Trinidadian guppies (Poecilia reticulata) along with pedigrees to test whether there are fitness benefits correlated with dispersal. Combining these ecological and molecular datasets allows us to directly measure the...

Data from: Local diversity in phenological responses of migratory lake sturgeon to warm winters

Tyler Buchinger, Darryl Hondorp & Charles Krueger
Rich intraspecific diversity in traits that shape responses to environmental conditions implies that effects of climate change will differ within species or even populations. Nevertheless, few studies investigate how different groups within species respond to climatic fluctuations, and most risk assessments rely upon species-wide generalizations. We studied effects of among-year variation in air temperature on the spring migratory phenology of a metapopulation of lake sturgeon (Acipenser fulvescens) within waters connecting Lake Huron and Lake Erie...

Data from: Traits across trophic levels interact to influence parasitoid establishment in biological control releases

Benjamin Jarrett & Marianna Szűcs
A central goal in ecology is to predict what governs a species’ ability to establish in a new environment. One mechanism driving establishment success is individual species’ traits, but the role of trait combinations among interacting species across different trophic levels are less clear. Deliberate or accidental species additions to existing communities provide opportunities to study larger scale patterns of establishment success. Biological control introductions are especially valuable because they contain data on both the...

Dataset for manuscript entitled: Switchgrass cropping systems affect soil carbon and nitrogen and microbial diversity and activity on marginal lands

Xiufen Li, Renee Petipas, Amanda Antoch, Yuan Liu, Holly Stel, Lukas Bell-Dereske, Darian Smercina, Cody Bekkering, Sarah Evans, Lisa Tiemann & Maren Friesen
Switchgrass (Panicum virgatum L.), as a dedicated bioenergy crop, can provide cellulosic feedstock for biofuel production while improving or maintaining soil quality. However, comprehensive evaluations of how switchgrass cultivation and nitrogen (N) management impact soil and plant parameters remain incomplete. We conducted field trials in three years (2016–2018) at six locations in the North Central Great Lakes Region to evaluate the effects of cropping systems (switchgrass, restored prairie, undisturbed control) and N rates (0, 56...

The shape of aroma: X-ray CT scans of citrus fruits, their separate tissues, and their individual oil glands

Erik Amezquita, Michelle Quigley, Tim Ophelders, Danelle Seymour, Elizabeth Munch & Daniel Chitwood
From preventing scurvy to being part of religious rituals, citrus are intrinsically connected to human health and perception. From tiny mandarins to head-sized pummelos, citrus capability of hybridization provides a vastly diverse array of fruit sizes and shapes, which in turn corresponds to a diversity of flavors and aromas. These sensory qualities are tightly linked to oil glands in the citrus skin. The oil glands are also key to understanding fruit development, and the essential...

Uncovering a miltiradiene biosynthetic gene cluster in the Lamiaceae reveals a dynamic evolutionary trajectory

Abigail E Bryson, Emily R Lanier, Kin H Lau, John P Hamilton, Brieanne Vaillancourt, Davis Mathieu, Alan E Yocca, Garret P Miller, Patrick P Edger, C Robin Buell & Bjoern Hamberger
The spatial organization of genes within plant genomes can drive evolution of specialized metabolic pathways. In this study we investigated the origin and subsequent evolution of a diterpenoid biosynthetic gene cluster (BGC) present throughout the Lamiaceae (mint) family. Terpenoids are important specialized metabolites in plants with diverse adaptive functions that enable environmental interactions, such as chemical defense. Based on core genes found in the BGCs of all species examined across the Lamiaceae, we predict a...

New non-native pseudocryptic Cyclorhipidion species (Coleoptera: Curculionidae: Scolytinae: Xyleborini) found in the United States as revealed in a multigene phylogeny

Anthony Cognato & Sarah Smith
Pseudocryptic species, those that are difficult to diagnose using traditional taxonomic methods, are serious impediments for recognizing the introduction of non-native species. Rapid identification of species facilitates a rapid response to newly introduced species which can lessen their damaging effects. This situation is acute for known pest species such as xyleborine ambrosia beetles which are difficult to identify given minute morphological, often variable, diagnostic characters. These beetles have been introduced into non-native temperate regions and...

Anchorage by seed mucilage prevents seed dislodgement in high surface flow: a mechanistic investigation

Vincent Pan, Cecilia Girvin & Eric LoPresti
Background and Aims: Seed mucilage is a common and highly diverse trait shared among thousands of angiosperm species. While long recognized that mucilage allows seeds to anchor to substrates (antitelechory), resisting abiotic and biotic dislodgement, we still lack a mechanistic understanding of this process. Methods: We propose a mechanistic model of how mucilage affects substrate anchorage and fluid resistance, ultimately contributing to dislodgement resistance. To test this model, we subjected mucilaginous seeds of 52 species,...

Climate-driven thermal opportunities and risks for leaf miners in aspen canopies

H. Arthur Woods, Geoffrey Legault, Joel Kingsolver, Sylvain Pincebourde, Alisha Shah & Beau Larkin
In tree canopies, incoming solar radiation interacts with leaves and branches to generate temperature differences within and among leaves, presenting thermal opportunities and risks for leaf-dwelling ectotherms. Although leaf biophysics and insect thermal ecology are well understood, few studies have examined them together in single systems. We examined temperature variability in aspen canopies, Populus tremuloides, and its consequences for a common herbivore, the leaf-mining caterpillar Phyllocnistis populiella. We shaded leaves in the field and measured...

Data From - TE Density: a tool to investigate the biology of transposable elements

Scott Teresi & Patrick Edger
Background: Transposable elements (TEs) are powerful creators of genotypic and phenotypic diversity due to theirinherent mutagenic capabilities and in this way they serve as a deep reservoir of sequences for genomic variation. As agents of genetic disruption, a TE’s potential to impact phenotype is partially a factor of its location in the genome. Previous research has shown TEs’ ability to impact the expression of neighboring genes, however our understanding of this trend is hampered by...

Normalized linear counts from NanoString autoimmune profiling panel and summary of statistical analyses

Lauren Heine
Though dependent on genetic anomalies, clinical manifestations of the human autoimmune disease systemic lupus erythematosus (lupus) can be triggered by environmental exposures including inhalation toxicants such as crystalline silica dust (cSiO2), tobacco smoke, and ambient air particles. Prednisone, a glucocorticoid (GC), is a keystone therapy for managing lupus flaring and progression, however, long-term use is associated with many adverse side effects. Here, we characterized the dose-dependent immunomodulation and toxicity of prednisone in a preclinical model...
