Data from: Nocturnal flight-calling behaviour predicts vulnerability to artificial light in migratory birds

Benjamin M. Winger, Brian C. Weeks, Andrew Farnsworth, Andrew W. Jones, Mary Hennen & David E. Willard
Understanding interactions between biota and the built environment is increasingly important as human modification of the landscape expands in extent and intensity. For migratory birds, collisions with lighted structures are a major cause of mortality, but the mechanisms behind these collisions are poorly understood. Using 40 years of collision records of passerine birds, we investigated the importance of species’ behavioral ecologies in predicting rates of building collisions during nocturnal migration through Chicago, IL and Cleveland,...

Data from: Phylogeny, ancestors, and anagenesis in the hominin fossil record

Caroline Parins-Fukuchi, Elliot Greiner, Laura M. MacLatchy & Daniel C. Fisher
Probabilistic approaches to phylogenetic inference have recently gained traction in paleontological studies. Because they directly model processes of evolutionary change, probabilistic methods facilitate a deeper assessment of variability in evolutionary patterns by weighing evidence for competing models. Although phylogenetic methods used in paleontological studies have generally assumed that evolution proceeds by splitting cladogenesis, extensions to previous models help explore the potential for morphological and temporal data to provide differential support for contrasting modes of evolutionary...

Data from: Differential changes in bone strength of two inbred mouse strains following administration of a sclerostin-neutralizing antibody during growth

Noah J. Mathis, Emily N. Adaniya, Lauren M. Smith, Alexander G. Robling, Karl J. Jepsen & Stephen H. Schlecht
Administration of sclerostin-neutralizing antibody (Scl-Ab) treatment has been shown to elicit an anabolic bone response in growing and adult mice. Prior work characterized the response of individual mouse strains but did not establish whether the impact of Scl-Ab on whole bone strength would vary across different inbred mouse strains. Herein, we tested the hypothesis that two inbred mouse strains (A/J and C57BL/6J (B6)) will show different whole bone strength outcomes following sclerostin-neutralizing antibody (Scl-Ab) treatment...

We anticipate this curated dataset will facilitate machine learning research in heliophysics and the physical sciences generally, increasing the scientific return of the SDO mission. This work is a...

Data from: Heterochrony in chimpanzee and bonobo spatial memory development

Alexandra G. Rosati
Objectives: The emergence of human-unique cognitive abilities has been linked to our species' extended juvenile period. Comparisons of cognitive development across species can provide new insights into the evolutionary mechanisms shaping cognition. This study examined the development of different components of spatial memory, cognitive mechanisms that support complex foraging, by comparing two species with similar life history that vary in wild ecology: bonobos (Pan paniscus) and chimpanzees (Pan troglodytes). Materials and methods: Spatial memory development...

Data from: Flexible gaze-following in rhesus monkeys

Rosemary Bettle & Alexandra G. Rosati
Humans are characterized by complex social cognitive abilities that emerge early in development. Comparative studies of nonhuman primates can illuminate the evolutionary history of these social capacities. We examined the cognitive skills that rhesus monkeys (Macaca mulatta) use to follow gaze, a foundational skill in human social development. While rhesus monkeys can make inferences about others’ gaze when competing, it is unclear how they think about gaze information in other contexts. In study 1, monkeys...

A new species of croton (Euphorbiaceae) from a Madagascan lineage discovered in coastal Kenya

Veronicah Ngumbau, Mwadime Nyange, Neng Wei, Benjamin Van Ee, Paul Berry, Itambo Malombe, Guang-Wan Hu & Qing-Feng Wang
Croton kinondoensis, a new species from Kenya, is described and illustrated here with photographs. It is found in the sacred Kaya Kinondo Forest, one of the last remaining coastal forests patches in Kenya. Its morphology and systematic position based on ITS and trnL-F DNA sequence data clearly place it within the Adenophorus Group of Croton, a clade of ca. 15 species otherwise known only from Madagascar and the Comoros Archipelago. Its closest affinities appear to...

Belowground competition can influence the evolution of root traits

Sara Colom & Regina Baucom
Although root traits play a critical role in mediating plant-plant interactions and resource acquisition from the soil environment, research examining if and how belowground competition can influence the evolution of root traits remains largely unexplored. Here we examine the potential that root traits may evolve as a target of selection from interspecific competition using Ipomoea purpurea and I. hederacea, two closely related morning glory species that commonly co-occur in the United States as a model...

Shared morphological consequences of global warming in North American migratory birds

Brian Weeks, David Willard, Marketa Zimova, Aspen Ellis, Max Witynski, Mary Hennen & Ben Winger
Increasing temperatures associated with climate change are predicted to cause reductions in body size, a key determinant of animal physiology and ecology. Using a four‐decade specimen series of 70 716 individuals of 52 North American migratory bird species, we demonstrate that increasing annual summer temperature over the 40‐year period predicts consistent reductions in body size across these diverse taxa. Concurrently, wing length – an index of body shape that impacts numerous aspects of avian ecology...

Data from: Environmental filtering structures fungal endophyte communities in tree bark

Peter Pellitier, Donald Zak & Sydney Salley
The factors that control the assembly and composition of endophyte communities across plant hosts remains poorly understood. This is especially true for endophyte communities inhabiting inner tree bark, one of the least studied components of the plant microbiome. Here, we test the hypothesis that bark of different tree species acts as an environmental filter structuring endophyte communities, as well as the alternative hypothesis, that bark acts as a passive reservoir that accumulates a diverse assemblage...

Data from: A phylogenomic framework for pelagiarian fishes (Acanthomorpha: Percomorpha) highlights mosaic radiation in the open ocean

Matthew Friedman, Kara Feilich, Hermione Beckett, Michael Alfaro, Brant Faircloth, David Černý, Masaki Miya, Thomas Near & Richard Harrington
The fish clade Pelagiaria, which includes tunas as its most famous members, evolved remarkable morphological and ecological variety in a setting not generally considered conducive to diversification: the open ocean. Relationships within Pelagiaria have proven elusive due to short internodes subtending major lineages suggestive of rapid early divergences. Using a novel sequence dataset of over 1000 ultraconserved DNA elements (UCEs) for 94 of the 286 species of Pelagiaria (more than 70% of genera), we provide...

A Paleocene (Danian) marine osteoglossid (Teleostei, Osteoglossomorpha) from the Nuussuaq Basin of Greenland, with a brief review of Palaeogene marine bonytongue fishes

Alessio Capobianco, Ethan Foreman & Matt Friedman
The early Palaeogene represents a key interval in the evolution of modern marine fish faunas. Together with the first appearances of many familiar fish lineages characteristic of contemporary marine environments, early Palaeogene marine deposits worldwide feature the occurrence of osteoglossid bonytongues. Their presence in marine rocks is surprising, as these fishes are strictly associated with freshwater environments in modern settings and other parts of the fossil record. Despite its possible relevance to faunal recovery after...

Data from: Estimating diversification rates on incompletely-sampled phylogenies: theoretical concerns and practical solutions

Jonathan Chang, Daniel L. Rabosky & Michael E. Alfaro
Molecular phylogenies are a key source of information about the tempo and mode of species diversification. However, most empirical phylogenies do not contain representatives of all species, such that diversification rates are typically estimated from incompletely sampled data. Most researchers recognize that incomplete sampling can lead to biased rate estimates, but the statistical properties of methods for accommodating incomplete sampling remain poorly known. In this point of view, we demonstrate theoretical concerns with the widespread...

The paper corresponding to the work is Walch et al., "Sleep stage prediction with...

Data from: Male-mediated prenatal loss: functions and mechanisms

Matthew Zipple, Eila K. Roberts, Susan C. Alberts & Jacinta C. Beehner
Sexually selected infanticide has been the subject of intense empirical and theoretical study for decades; a related phenomenon, male-mediated prenatal loss, has received much less attention in evolutionary studies. Male-mediated prenatal loss occurs when inseminated or pregnant females terminate reproductive effort following exposure to a non-sire male, either through implantation failure or pregnancy termination. Male-mediated prenatal loss encompasses two sub-phenomena: sexually selected feticide and the Bruce effect. In this review, we lay out a framework...

Data from: The role of fish life histories in allometrically scaled food-web dynamics

Stephanie Bland, Fernanda Valdovinos, Jeffrey Hutchings & Anna Kuparinen
1. Body size determines key ecological and evolutionary processes of organisms. Therefore, organisms undergo extensive shifts in resources, competitors and predators as they grow in body size. While empirical and theoretical evidence show that these size-dependent ontogenetic shifts vastly influence the structure and dynamics of populations, theory on how those ontogenetic shifts affect the structure and dynamics of ecological networks is still virtually absent. 2. Here, we expand the Allometric Trophic Network (ATN) theory in...

Census of Population and Housing, 1990: Extract Data

Terry K. Adams
This extraction of data from the 1990 decennial Census files (CENSUS OF POPULATION AND HOUSING, 1990 UNITED STATES: SUMMARY TAPE FILES 3A AND 3B (ICPSR 9694, 9693)) was designed to provide a set of contextual variables to be matched to any survey dataset that has been coded for the geographic location of respondents. Over 120 variables were selected from original Census sources, and more than 100 variables were derived from those component variables. The variables...

Data from: An R package and online resource for macroevolutionary studies using the ray-finned fish tree of life

Jonathan Chang, Daniel L. Rabosky, Stephen A. Smith & Michael E. Alfaro
1. Comprehensive, time-scaled phylogenies provide a critical resource for many questions in ecology, evolution, and biodiversity. Methodological advances have increased the breadth of taxonomic coverage in phylogenetic data; however, accessing and reusing these data remain challenging. 2. We introduce the Fish Tree of Life website and associated R package fishtree to provide convenient access to sequences, phylogenies, fossil calibrations, and diversification rate estimates for the most diverse group of vertebrate organisms, the ray-finned fishes. The...

Data from: Age-structure and transient dynamics in epidemiological systems

Felicia Maria G. Magpantay, Aaron A. King & Pejman Rohani
Mathematical models of childhood diseases date back to the early twentieth century. In several cases, models that make the simplifying assumption of homogeneous time-dependent transmission rates give good agreement with data in the absence of secular trends in population demography or transmission. The prime example is afforded by the dynamics of measles in industrialized countries in the pre-vaccine era. Accurate description of the transient dynamics following the introduction of routine vaccination has proved more challenging,...

Expanded 3D nanofibre sponge scaffolds by gas-foaming technique enhance peripheral nerve regeneration

Feng Rao, Zhipeng Yuan, Ming Li, Fei Yu, Xingxing Fang, Baoguo Jiang, Yongqiang Wen & Peixun Zhang
Peripheral nerve injury has troubled clinical doctors for many years. To obtain better function recovery of peripheral nerve repair at the base of hollow nerve guidance conduit (NGC), many NGCs with fillers were developed in the application of tissue-engineered nerve graft. In this study, expanded 3D nanofibre sponge scaffolds with orientation and porosity were first fabricated by electrospinning and gas-foaming technique. Polylactic acid (PLA)/silk fibroin nanofibre sponge scaffolds were prepared as filler to construct 3D...

Data from: Long-term dynamics of liana seedlings suggest decelerating increases in liana relative abundance over time

Maria Natalia Umaña, Eric Manzané-Pinzón & Liza Comita
Over the past decades, tropical forests have experienced both compositional and structural changes. In the Neotropics, researchers at multiple sites have observed significant increases in the abundance and biomass of lianas (i.e. woody vines) relative to trees. However, the role of dynamics at early life stages in contributing to increasing liana abundance remains unclear. We took advantage of a unique dataset on seedling dynamics over 16 years in ~20,000 1-m2plots in a tropical forest in...
