Data from: Cross-scale occupancy dynamics of a post-fire specialist in response to variation across a fire regime

Morgan W. Tingley, Andrew N. Stillman, Robert L. Wilkerson, Christine A. Howell, Sarah C. Sawyer & Rodney B. Siegel
1. Fire creates challenges and opportunities for wildlife through rapid destruction, modification, and creation of habitat. Fire has spatially variable effects on landscapes, however, and for species that benefit from the ephemeral resource patches created by fire, it is critical to understand characteristics of fires that promote post-fire colonization and persistence, and the spatial scales on which they operate. 2. Using a model post-fire specialist, the black-backed woodpecker (Picoides arcticus), we examined how colonization and...

Data from: Contemporaneous radiations of fungi and plants linked to symbiosis

François Lutzoni, Michael D. Nowak, Michael E. Alfaro, Valérie Reeb, Jolanta Miadlikowska, Michael Krug, A. Elizabeth Arnold, Louise A. Lewis, David L. Swofford, David Hibbett, Khidir Hilu, Timothy Y. James, Dietmar Quandt & Susana Magallón
Interactions between fungi and plants, including parasitism, mutualism, and saprotrophy, have been invoked as key to their respective macroevolutionary success. Here we evaluate the origins of plant-fungal symbioses and saprotrophy using a time-calibrated phylogenetic framework that reveals linked and drastic shifts in diversification rates of each kingdom. Fungal colonization of land was associated with at least two origins of terrestrial green algae and preceded embryophytes (as evidenced by losses of fungal flagellum, ca. 720 Ma),...

Data from: Divergent trait and environment relationships among parallel radiations in Pelargonium (Geraniaceae): a role for evolutionary legacy?

Timothy E. Moore, Carl D. Schlichting, Matthew E. Aiello-Lammens, Kerri Mocko & Cynthia S. Jones
Functional traits in closely related lineages are expected to vary similarly along common environmental gradients due to shared evolutionary and biogeographic history, or legacy effects, and due to biophysical tradeoffs in construction. We test these predictions in Pelargonium, a relatively recent evolutionary radiation. Bayesian phylogenetic mixed effects models assessed, at the subclade level, associations between plant height, leaf area, leaf nitrogen content and leaf mass per area (LMA), and five environmental variables capturing temperature and...

Data from: Organellar phylogenomics inform systematics in the green algal family Hydrodictyaceae (Chlorophyceae) and provide clues to the complex evolutionary history of plastid genomes in the green algal Tree of Life.

Hilary A. McManus, Karolina Fučíková, Paul O. Lewis, Louise A. Lewis & Kenneth G. Karol
Premise of the study: Phylogenomic analyses across the green algae are resolving relationships at the class, order and family levels, and highlighting dynamic patterns of evolution in organellar genomes. Here we present a within-family phylogenomic study to resolve genera and species relationships in the family Hydrodictyaceae (Chlorophyceae), for which poor resolution in previous phylogenetic studies, along with divergent morphological traits, have precluded taxonomic revisions. Methods: Complete plastome sequences and mitochondrial protein-coding gene sequences were acquired...

Data from: Moth body size increases with elevation along a complete tropical elevational gradient for two hyperdiverse clades

Gunnar Brehm, Dirk Zeuss & Robert K. Colwell
The body size of an animal is probably its most important functional trait. For arthropods, environmental drivers of body size variation are still poorly documented and understood, especially in tropical regions. We use a unique dataset for two species-rich, phylogenetically independent moth taxa (Lepidoptera: Geometridae; Arctiinae), collected along an extensive tropical elevational gradient in Costa Rica, to investigate the correlates and possible causes of body-size variation. We studied 15,047 specimens (794 species) of Geometridae and...

Data from: Age‐dependent habitat relationships of a burned forest specialist emphasise the role of pyrodiversity in fire management

Andrew N. Stillman, Rodney B. Siegel, Robert L. Wilkerson, Matthew Johnson & Morgan W. Tingley
1. Variation in fire characteristics, termed pyrodiversity, plays an important role in structuring post-fire communities, but little is known about the importance of pyrodiversity for individual species. The availability of diverse post-fire habitats may be key for fire-associated species if they require different resources at different life history stages. 2. We tested for age-specific habitat relationships in the black-backed woodpecker, a post-fire specialist. We used radio-telemetry to track fledgling and adult woodpeckers in burned forests...

Maga Gei, Danaë M. A. Rozendaal, Lourens Poorter, Frans Bongers, Janet I. Sprent, Mira D. Garner, T. Mitchell Aide, José Luis Andrade, Patricia Balvanera, Justin M. Becknell, Pedro H.S. Brancalion, George A. L. Cabral, Ricardo Gomes César, Robin L. Chazdon, Rebecca J. Cole, Gabriel Dalla Colletta, Ben De Jong, Julie S. Denslow, Daisy H. Dent, Saara J. DeWalt, Juan Manuel Dupuy, Sandra M. Durán, Mário Marcos Do Espírito Santo, G. Wilson Fernandes, Yule Roberta Ferreira Nunes … & Jennifer S. Powers
The nutrient demands of regrowing tropical forests are partly satisfied by nitrogen (N)-fixing legume trees, but our understanding of the abundance of those species is biased towards wet tropical regions. Here we show how the abundance of Leguminosae is affected by both recovery from disturbance and large-scale rainfall gradients through a synthesis of forest-inventory plots from a network of 42 Neotropical forest chronosequences. During the first three decades of natural forest regeneration, legume basal area...

Data from: Testing for human impacts in the mismatch of living and dead ostracode assemblages at nested spatial scales in subtropical lakes from the Bahamian archipelago

Andrew V. Michelson, Susan M. Kidwell, Lisa E. Park Boush & Jeanine L. Ash
Naturally time-averaged accumulations of skeletal remains – death assemblages – provide reliable, albeit temporally coarse, information on the species composition and structure of communities in diverse settings, and their mismatch with local living communities usually signals recent human-driven ecological change. Here, we present the first test of live-dead mismatch as an indicator of human stress using ostracodes. On three islands along a gradient of human population density in the Bahamas, we compared the similarity of...

Data from: Towards resolving and redefining Amphipyrinae (Lepidoptera, Noctuoidea, Noctuidae): a massively polyphyletic taxon

Kevin L. Keegan, J. Donald Lafontaine, Niklas Wahlberg & David L. Wagner
Amphipyrinae have long been a catchall taxon for Noctuidae, with most members lacking discernible morphological synapomorphies that would allow their assignment to one of the many readily diagnosable noctuid subfamilies. Here data from seven gene regions (>5,500 base pairs) for more than 120 noctuid genera are used to infer a phylogeny for Amphipyrinae and related subfamilies. Sequence data for 57 amphipyrine genera—most represented by the type species of the genus—are examined. Presented here are: the...

Data from: Development and validation of a weather-based warning system to advise fungicide applications to control dollar spot on turfgrass

Damon L. Smith, James P. Kerns, Nathan R. Walker, Andrea F. Payne, Brandon Horvath, John C. Inguagiato, John E. Kaminski, Maria Tomaso-Peterson & Paul L. Koch
Dollar spot is one of the most common diseases of golf course turfgrass and numerous fungicide applications are often required to provide adequate control. Weather-based disease warning systems have been developed to more accurately time fungicide applications; however, they tend to be ineffective and are not currently in widespread use. The primary objective of this research was to develop a new weather-based disease warning system to more accurately advise fungicide applications to control dollar spot...

Data from: Genome-specific histories of divergence and introgression between an allopolyploid unisexual salamander lineage and two ancestral sexual species

Robert D. Denton, Ariadna E. Morales & H. Lisle Gibbs
Quantifying introgression between sexual species and polyploid lineages traditionally thought to be asexual is an important step in understanding what drives the longevity of putatively asexual groups. Here, we capitalize on three recent innovations—ultraconserved element (UCE) sequencing, bioinformatic techniques for identifying genome-specific variation in polyploids, and model-based methods for evaluating historical gene flow—to measure the extent and tempo of introgression over the evolutionary history of an allopolyploid lineage of all-female salamanders and two ancestral sexual...

Data from: Natural selection and the predictability of evolution in Timema stick insects

Patrik Nosil, Romain Villoutreix, Clarissa F. De Carvalho, Tim E. Farkas, Victor Soria-Carrasco, Jeff L. Feder, Bernard J. Crespi & Zachariah Gompert
Predicting evolution remains difficult. We studied the evolution of cryptic body coloration and pattern in a stick insect using 25 years of field data, experiments, and genomics. We found that evolution is more difficult to predict when it involves a balance between multiple selective factors and uncertainty in environmental conditions than when it involves feedback loops that cause consistent back-and-forth fluctuations. Specifically, changes in color-morph frequencies are modestly predictable through time (r2 = 0.14) and...

Data from: Consequences of breeding system for body condition and survival throughout the annual cycle of tidal marsh sparrows

Alyssa Borowske, Christopher R. Field, Katharine J. Ruskin & Chris S. Elphick
An individual’s body condition and probability of survival can change throughout the annual cycle, based on the combined effects of many factors, including reproductive investment during breeding, colder temperatures during winter, and elevated risks during migration. We evaluated body condition and survival during breeding and non-breeding periods in two closely related species with notably different reproductive systems. Male and female saltmarsh sparrows (Ammodramus caudacutus) represent extremes in parental care: males perform none, leaving females to...

Data from: The effects of rainforest fragment area on the strength of plant-pathogen interactions

Ashwin Viswanathan, Jaboury Ghazoul, Ganesh Honwad, N. Arun Kumar & Robert Bagchi
Pathogenic interactions between fungi and plants facilitate plant species coexistence and tropical rainforest diversity. Such interactions, however, may be affected by forest fragmentation as fungi are susceptible to anthropogenic disturbance. To examine how fragmentation affects fungus-induced seed and seedling mortality, we sowed seeds of six plant species in soils collected from 21 forest fragments. We compared seedling establishment in unmanipulated soils to soils treated with fungicides. Fungicides increased germination of Toona ciliata seeds and decreased...

Data from: Social context affects thermoregulation but not activity level during avian immune response

Grace J. Vaziri, Manju M. Johny, Petrutza C. Caragea & James S. Adelman
Determining how an animal’s social context alters its immune responses will help us understand how pathogens impact individual health and spread within groups. Several studies have shown that group-housed animals can suppress components of the acute phase immune response, specifically sickness behaviors like lethargy. However, we do not know whether individuals alter sickness behaviors or other components of the acute phase response, including thermoregulation, in response to the infection status of other group members. We...

Fitting Dynamic Regression Models to Seshat Data - Supplemental Material

Peter Turchin
This article presents a general statistical approach suitable for the analysis of time-resolved (time-series) cross-cultural data. The goal is to test theories about the evolutionary processes that generate cultural change. This approach allows us to investigate the effects of predictor variables (proxying for theory-suggested mechanisms), while controlling for spatial diffusion and autocorrelations due to shared cultural history (known as Galton’s Problem). It also fits autoregressive terms to account for serial correlations in the data and...

Data from: Microscale trait-environment associations in two closely-related South African shrubs

Nora Mitchell & Kent E. Holsinger
Premise of the study: Plant traits are often associated with the environments in which they occur, but these associations often differ across spatial and phylogenetic scales. Here we study the relationship between microenvironment, microgeographical location, and traits within populations using co-occurring populations of two closely related evergreen shrubs in the genus Protea. Methods: We measured a suite of functional traits on 147 plants along a single steep mountainside where both species occur, and we used...

Data from: Robust quantification of fish early life CO2 sensitivities via serial experimentation

Hannes Baumann, Emma L. Cross, Christopher S. Murray & Chris S. Murray
Despite the remarkable expansion of laboratory studies, robust estimates of single species CO2 sensitivities remain largely elusive. We conducted a meta-analysis of 20 CO2 exposure experiments conducted over six years on offspring of wild Atlantic silversides (Menidia menidia) to robustly constrain CO2 effects on early life survival and growth. We conclude that early stages of this species are generally tolerant to CO2 levels of ~ 2,000 µatm, likely because they already experience these conditions on...
