River network rearrangements promote speciation in lowland Amazonian birds

Lukas Musher
Large Amazonian rivers impede dispersal for many species, but lowland river networks frequently rearrange, thereby altering the location and effectiveness of river-barriers through time. These rearrangements may promote biotic diversification by facilitating episodic allopatry and secondary contact among populations. We sequenced genome-wide markers to evaluate histories of divergence and introgression in six Amazonian avian species-complexes. We first tested the assumption that rivers are barriers for these taxa and found that even relatively small rivers facilitate...

Haemosporidian parasites and incubation period influence plumage coloration in tanagers (Passeriformes: Thraupidae)

Birds are visually oriented and use their plumage coloration as an important signaling trait in social communication. Males and females may have different patterns of plumage coloration, a phenomenon known as sexual dichromatism. Because males tend to have more complex plumages, sexual dichromatism is usually attributed to female choice. However, plumage coloration is partly condition-dependent, therefore other selective pressures affecting individuals’ success may also drive the evolution of this trait. Here we used tanagers to...

Coronavirus disease 2019 (COVID-19) has caused high morbidity and mortality worldwide. Since there is not enough evidence of risk factors of SARS-CoV-2 transmission, this study aimed to evaluate them. This survey-based study was conducted across 66 countries from May to November 2020 among suspected and confirmed individuals with COVID-19. The stepwise AIC method was utilized to determine the optimal multivariable logistic regression to explore predictive factors of SARS-CoV-2 transmission. Among 2372 respondents who participated in...

Impacts of development and adult sex on brain cell numbers in the Black Soldier Fly, Hermetia illucens L. (Diptera: Stratiomyidae)

Meghan Barrett, R Keating Godfrey, Emily J. Sterner & Edward A. Waddell
The Black Soldier Fly (Hermetia illucens, Diptera: Stratiomyidae) has been introduced across the globe, with numerous industry applications predicated on its tremendous growth during the larval stage. However, basic research on H. illucens biology (for example, studies of their central nervous system) are lacking. Despite their small brain volumes, insects are capable of complex behaviors; understanding how these behaviors are completed with such a small amount of neural tissue requires understanding processing power (e.g. number...

Effect of primary tumor resection on survival in patients with asymptomatic unresectable metastatic colorectal cancer: a systematic review and meta-analysis

Chengren Zhang, Cong Cao, Lili Liu, Yaochun Lv, Jingjing Li, Jiyong Lu, Shuai Wang, Binbin Du & Xiongfei Yang
It remains controversial whether primary tumor resection (PTR) improves survival in patients with asymptomatic, unresectable metastatic colorectal cancer (mCRC). Therefore, we conducted a meta-analysis to assess the latest evidence on clinical outcomes. We systematically searched PubMed, Web of Science, Cochrane Library, and Embase databases for eligible studies published between database inception and May 2022. RevMan 5.4 and Stata 16.0 were used for the meta-analysis. A total of nine studies were included, including four randomized controlled...

Chemotherapy plus panitumumab/cetuximab versus chemotherapy plus bevacizumab in wild-type KRAS/RAS metastatic colorectal cancer: a meta-analysis

Chengren Zhang, Lili Liu, Yaochun Lv, Jingjing Li, Cong Cao, Jiyong Lu, Shuai Wang, Binbin Du & Xiongfei Yang
It remains controversial which targeted monoclonal antibodies combined with chemotherapy can provide better efficacy in wild-type KRAS/RAS metastatic colorectal cancer (mCRC) patients. Therefore, we used this meta-analysis to assess the latest evidence of clinical outcomes. We systematically searched PubMed, Web of Science, Cochrane Library and Embase databases for eligible studies published from database inception to May 2022. RevMan 5.4 was used to conduct the meta-analysis. 11 RCTs involving a total of 3575 patients were included....

Optimization of the vancomycin administration regimen by clinical pharmacists based on a population pharmacokinetics model: a prospective interventional study

Haodi Lu, Lufen Duan, Yanxia Yu, Jingjing Li, Lu Shi, Sudong Xue, Qian Zhang, Qin Zhou, Chenqi Zhu, Erning Shang, Xinxin Yan & Lian Tang
In vancomycin treatment, the rates of correct blood sampling and initial trough concentrations within the target range are very low. Studies of interventions by clinical pharmacists based on population pharmacokinetics (PPK) models are limited. This study aimed to evaluate the intervention effect of clinical pharmacist-mediated optimization of the vancomycin administration regimen based on a PPK model. Retrospectively enrolled patients constituted the control group, and prospectively enrolled patients constituted the intervention group. The vancomycin administration regimen,...

Dataset for: Intercontinental analysis of temperate steppe stream food webs reveals consistent autochthonous support of fishes

Quantifying the trophic basis of production for freshwater metazoa at broad spatial scales is key to understanding ecosystem function and has been a research priority for decades. However, previous lotic food web studies have been limited by geographic coverage or methodological constraints. We used compound-specific stable carbon isotope analysis of amino acids to estimate basal resource contributions to fish consumers in streams spanning grassland, montane, and semi-arid ecoregions of the temperate steppe biome on two...

The giant clam photosymbiosis is a physically optimized photoconversion system for the most intense sunlight on Earth

Amanda Holt, Alison Sweeney & Lincoln Rehm
Giant clams are photosymbiotic with unicellular algae ("zooxanthellae") organized in the clam's mantle tissue. This tissue has an especially low albedo for a photosynthetic system, generally less than 10\% at all visible wavelengths. This efficient absorbance of light occurs in the ecological context of the high solar irradiances in intertidal habitats near the equator. At these light levels, photosynthetic systems typically adapt to absorb less light in order to prevent radiative damage to chloroplasts. Giant...

Partner fidelity and environmental filtering preserve stage-specific turtle ant gut symbioses for over 40 million years

Yi Hu, Catherine D’Amelio, Benoît Béchade, Christian Cabuslay, Piotr Lukasik, Jon Sanders, Shauna Price, Emily Fanwick, Scott Powell, Corrie Moreau & Jacob Russell
Sustaining beneficial gut symbioses presents a major challenge for animals, Including holometabolous insects. Social insects may meet such challenges through behavioral symbiont transfer and transgenerational inheritance through colony founders. We address such potential through colony-wide explorations across 13 eusocial, holometabolous ant species in the genus Cephalotes. Through amplicon sequencing and qPCR, we show that previously characterized worker microbiomes are largely conserved across adult castes, that adult microbiomes exhibit strong trends of phylosymbiosis, and that Cephalotes...
