Data from: Relationships of the Indian phytosaur Parasuchus hislopi Lydekker, 1885

Christian F. Kammerer, Richard J. Butler, Saswati Bandyopadhyay & Michelle R. Stocker
The neotype skull of the Indian phytosaur Parasuchus hislopi Lydekker, 1885 (ISI R42) is re-evaluated and compared with the type material of other basal phytosaurs. Parasuchus hislopi is extremely similar to species previously placed in Paleorhinus (P. bransoni and P. angustifrons), sharing with them such characters as a series of nodes on the lateral surface of the jugal, paired ridges on the squamosal and a frontal depression. Parasuchus hislopi represents a valid species: it can...

Data from: Urban living alters moult dynamics in a passerine

Sydney F. Hope, Frank A. Stabile & Luke K. Butler
Urbanization and habitat fragmentation can alter the timing of life history events, potentially leading to phenological mismatches, carryover effects, and fitness costs. Whereas urbanization and fragmentation are known to alter important aspects of breeding in many bird species, little is known about the effects of urbanization and habitat fragmentation on moult. To investigate the effects of urbanization and fragmentation on the annual moult, we compared the moult dynamics (onset, duration, and intensity) of urban, fragmented...

Data from: Feeder use predicts both acquisition and transmission of a contagious pathogen in a North American songbird

James S. Adelman, Sahnzi C. Moyers, Damien R. Farine & Dana M. Hawley
Individual heterogeneity can influence the dynamics of infectious diseases in wildlife and humans alike. Thus, recent work has sought to identify behavioural characteristics that contribute disproportionately to individual variation in pathogen acquisition (super-receiving) or transmission (super-spreading). However, it remains unknown whether the same behaviours enhance both acquisition and transmission, a scenario likely to result in explosive epidemics. Here, we examined this possibility in an ecologically relevant host–pathogen system: house finches and their bacterial pathogen, Mycoplasma...

Data from: High precipitation and seeded species competition reduce seeded shrub establishment during dryland restoration

Matthew J. Rinella, Darcy H. Hammond, Ana-Elisa M. Bryant & Brian J. Kozar
Drylands comprise 40% of Earth's land mass and are critical to food security, carbon sequestration, and threatened and endangered wildlife. Exotic weed invasions, overgrazing, energy extraction, and other factors have degraded many drylands, and this has placed an increased emphasis on dryland restoration. The increased restoration focus has generated a wealth of experience, innovations and empirical data, yet the goal of restoring diverse, native, dryland plant assemblages composed of grasses, forbs, and shrubs has generally...

Data from: Alternative translation initiation codons for the plastid maturase MatK: unraveling the pseudogene misconception in the Orchidaceae

Michelle M. Barthet, Keenan Moukarzel, Kayla N. Smith, Jaimin Patel & Khidir W. Hilu
Background: The plastid maturase MatK has been implicated as a possible model for the evolutionary “missing link” between prokaryotic and eukaryotic splicing machinery. This evolutionary implication has sparked investigations concerning the function of this unusual maturase. Intron targets of MatK activity suggest that this is an essential enzyme for plastid function. The matK gene, however, is described as a pseudogene in many photosynthetic orchid species due to presence of premature stop codons in translations, and...

Data from: Hunting, exotic carnivores, and habitat loss: anthropogenic effects on a native carnivore community, Madagascar

Zach J. Farris, Christopher D. Golden, Sarah Karpanty, Asia Murphy, Dean Stauffer, Felix Ratelolahy, Vonjy Andrianjakarivelo, Christopher M. Holmes & Marcella J. Kelly
The wide-ranging, cumulative, negative effects of anthropogenic disturbance, including habitat degradation, exotic species, and hunting, on native wildlife has been well documented across a range of habitats worldwide with carnivores potentially being the most vulnerable due to their more extinction prone characteristics. Investigating the effects of anthropogenic pressures on sympatric carnivores is needed to improve our ability to develop targeted, effective management plans for carnivore conservation worldwide. Utilizing photographic, line-transect, and habitat sampling, as well...

Data from: Body condition indices predict reproductive success but not survival in a sedentary, tropical bird

Olga Milenkaya, Daniel H. Catlin, Sarah Legge & Jeffrey R. Walters
Body condition may predict individual fitness because those in better condition have more resources to allocate towards improving their fitness. However, the hypothesis that condition indices are meaningful proxies for fitness has been questioned. Here, we ask if intraspecific variation in condition indices predicts annual reproductive success and survival. We monitored a population of Neochmia phaeton (crimson finch), a sedentary, tropical passerine, for reproductive success and survival over four breeding seasons, and sampled them for...

Data from: Phylogenetic distribution of symbiotic bacteria from Panamanian amphibians that inhibit growth of the lethal fungal pathogen Batrachochytrium dendrobatidis

Matthew H. Becker, Jenifer B. Walke, Lindsey Murrill, Douglas C. Woodhams, Laura K. Reinert, Louise A. Rollins-Smith, Elizabeth A. Burzynski, Thomas P. Umile, Kevin P. C. Minbiole & Lisa K. Belden
The introduction of next-generation sequencing has allowed for greater understanding of community composition of symbiotic microbial communities. However, determining the function of individual members of these microbial communities still largely relies on culture-based methods. Here, we present results on the phylogenetic distribution of a defensive functional trait of cultured symbiotic bacteria associated with amphibians. Amphibians are host to a diverse community of cutaneous bacteria and some of these bacteria protect their host from the lethal...

Data from: Lotic cyprinid communities can be structured as nest webs and predicted by the stress-gradient hypothesis

Brandon K. Peoples, Lori A. Blanc & Emmanuel A. Frimpong
1. Little is known about how positive biotic interactions structure animal communities. Nest association is a common reproductive facilitation in which associate species spawn in nests constructed by host species. Nest-associative behaviour is nearly obligate for some species, but facultative for others; this can complicate interaction network topology. 2. Nest web diagrams can be used to depict interactions in nesting-structured communities and generate predictions about those interactions, but have thus far only been applied to...

Data from: Reconstructing changes in the genotype, phenotype, and climatic niche of an introduced species

Daniel Z. Atwater, U. Uzay Sezen, Valorie Goff, Wenqian Kong, Andrew H. Paterson & Jacob N. Barney
An introduced species must contend with enormous environmental variation in its introduced range. In this study, we use niche models and ordination analyses to reconstruct changes in genotype, phenotype, and climatic niche of Johnsongrass (Sorghum halepense), which is regarded as one of the world's most threatening invasive plants. In the United States, Johnsongrass has rapidly evolved within- and among-population genetic diversity; our results show that genetic differentiation in expanding Johnsongrass populations has resulted in phenotypic...

Data from: Identifying differentially expressed genes under heat stress and developing molecular markers in orchardgrass (Dactylis glomerata L.) through transcriptome analysis

Lin K. Huang, Hai D. Yan, J. Wang, T. Frazier, X. X. Zhao, X. Q. Zhang, X. Huang, D. F. Yan, W. J. Zang, X. Ma, Y. Peng, Y. H. Yan, W. Liu & G. Yin
Orchardgrass (Dactylis glomerata L.) is a long-lived, cool-season forage grass that is commonly used for hay production. Despite its economic importance, orchardgrass genome remains relatively unexplored. In this study, we used Illumina RNA sequencing to identify gene-associated molecular markers, including simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), as well as heat stress-induced differentially expressed genes (DEGs) in two orchardgrass genotypes, ‘Baoxing’ (heat resistant) and ‘01998’ (heat susceptible). Approximately 163 million high-quality trimmed reads...
