Invasive species and biotic homogenization in temperate aquatic plant communities

Ranjan Muthukrishnan & Daniel Larkin
Aim: Biotic homogenization (BH), a reduction in the distinctness of species composition between geographically separated ecological communities in a region, is an important but underappreciated potential consequence of biological invasions. While BH theory has always considered invasions, it has generally been in a relatively narrow context, i.e., that the cosmopolitan nature of invasive species increases BH because of their shared presence across many locations. We sought to evaluate this component of BH as well as...

Documentário clássico e a voz que não vemos: revisitando as noções de “voz de Deus” e “voz over”

Renan Chaves
The article revisits the notions of “voice of God” and “voice over” in the context of classic documentary film. From filmic and textual primary sources, the article seeks to demonstrate that such expressions do not support the stylistic variety and ethical perspectives in classic documentary film. So they should be problematized and acknowledge the existence of a diverse and complex field concerning the presence of the voice.

Data from: Conspecific sperm precedence is reinforced, but postcopulatory sexual selection weakened, in sympatric populations of Drosophila

Dean M. Castillo & Leonie C. Moyle
Sexual selection can accelerate speciation by driving the evolution of reproductive isolation, but forces driving speciation could also reciprocally feedback on sexual selection. This might be particularly important in the context of ‘reinforcement’, where selection acts directly to increase prezygotic barriers to reduce the cost of heterospecific matings. Using assays of sperm competition within and between two sister species, we show a signature of reinforcement where these species interact: populations of Drosophila pseudoobscura that co-occur...

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...

Light availability and rhizobium variation interactively mediate the outcomes of legume-rhizobium symbiosis

Katy Heath, Justin Podowski, Stephanie Heniff, Christie Klinger, Jennifer Lau, Wendy Yang, Dylan Weese & Patricia Burke
Premise of the study: Nutrients, light, water, and temperature are key factors limiting the growth of individual plants in nature. Mutualistic interactions between plants and microbes often mediate resource limitation for both partners. In the mutualism between legumes and rhizobia, plants provide rhizobia with carbon in exchange for fixed nitrogen. Because partner quality in mutualisms is genotype-dependent, within-species genetic variation is expected to alter the responses of mutualists to changes in the resource environment. Here...

Data from: The origins of novelty from within the confines of homology: the developmental evolution of the digging tibia of dung beetles

David Linz, Hu Yonggang & Armin Moczek
Understanding the origin of novel complex traits is among the most fundamental goals in evolutionary biology. The most widely used definition of novelty in evolution assumes the absence of homology, yet where homology ends and novelty begins is increasingly difficult to parse as evo devo continuously revises our understanding of what constitutes homology. Here, we executed a case study to explore the earliest stages of innovation by examining the tibial teeth of tunneling dung beetles....

Is the Licensing of Grey Literature Using the Full Palette of “Contractual” Colors?: A Comparative Analysis of Grey Literature Terms of Use

Tomas Lipinski & Andrea Copeland
This paper reviews a sample of licenses or terms of use governing the use of grey collections. A license is a form of legal permission. It need not be a contract but often is. Some terms of service reviewed do not even provide permission per se but state a list or rules users should follow. From this analysis a list of best licensing practices or checklist of considerations can be offered. Regardless of the specific...

Conflicting signal in transcriptomic markers leads to a poorly resolved backbone phylogeny of Chalcidoid wasps

Junxia Zhang, Amelia R.I. Lindsey, Ralph S. Peters, John M. Heraty, Keith R. Hopper, John H. Werren, Ellen O. Martinson, James B. Woolley, Matt J. Yoder & Lars Krogmann
Chalcidoidea (Hymenoptera) are a megadiverse superfamily of wasps with astounding variation in both morphology and biology. Most species are parasitoids and important natural enemies of insects in terrestrial ecosystems. In this study, we explored a transcriptome-based phylogeny of Chalcidoidea and found that poorly resolved relationships could only be marginally improved by adding more genes (a total of 5,591) and taxa (a total of 65), proof-checking for errors of homology and contamination, and decreasing missing data....

Data from: Early predictors of outcomes of hospitalization for cirrhosis and assessment of the impact of race and ethnicity at safety-net hospitals

, Samuel Akinyeye, Zachary Fricker, Moinuddin Syed, Eric Orman, Lauren Nephew, Eduardo Vilar Gomez, James Slaven, Naga Chalasani, Maya Balakrishnan, Michelle Long, Bashar Attar & Marwan Ghabril
Background. Safety-net hospitals provide care for racially/ethnically diverse and disadvantaged urban populations. Their hospitalized patients with cirrhosis are relatively understudied and may be vulnerable to poor outcomes and racial/ethnic disparities. Aims. To examine the outcomes of patients with cirrhosis hospitalized at regionally diverse safety-net hospitals and the impact of race/ethnicity. Methods. A study of patients with cirrhosis hospitalized at 4 safety-net hospitals in 2012 was conducted. Demographic, clinical factors, and outcomes were compared between centers...
