Roundup causes embryonic development failure, alters metabolic pathways and gut microbiota functionality in non-target species

Luisa Orsini
Background: Research around the weedkiller Roundup is among the most contentious of the 21st century. Scientists have provided inconclusive evidence that the weedkiller causes cancer and other life-threatening diseases, while industry-paid research reports that the weedkiller has no adverse effect on humans or animals. Much of the controversial evidence on Roundup is rooted in the approach used to determine safe use of chemicals, defined by outdated toxicity tests.We apply a system biology approach to the...

Data from: Dietary constraints of phytosaurian reptiles revealed by dental microwear textural analysis

Jordan Bestwick, Andrew Jones, Mark Purnell & Richard Butler
Phytosaurs are a group of large, semi-aquatic archosaurian reptiles from the Middle–Late Triassic. They have often been interpreted as carnivorous or piscivorous due to their large size, morphological similarity to extant crocodilians and preservation in fluvial, lacustrine and coastal deposits. However, these dietary hypotheses are difficult to test, meaning that phytosaur ecologies and their roles in Triassic food webs remain incompletely constrained. Here, we apply dental microwear textural analysis to the three-dimensional sub-micrometre scale tooth...

Research data supporting the publication \"Synthesis and characterisation of Sr4Fe3-xCrxO10-δ : stabilisation of n=3 Ruddlesden-Popper phases through Cr doping\"

Abbey Jarvis, Peter Slater, Frank J Berry, Jose F Marco, Maria Sanchez-Arenillas, Giannantonio Cibin & Oliver Clemens
Ruddlesden-Popper type compounds have the general formula, An+1MnO3n+1±x (typically A is a rare earth, alkaline earth, M is a transition metal), and are constructed of perovskite-type layers separated by rock salt type blocks. While n=1,2 phases are typically straightforward to prepare, the synthesis of higher order (n>2) systems is difficult. In this paper we show that chromate (CrO42-) doping can be exploited to stabilise new n=3 Ruddlesden-Popper systems, Sr4Fe3-xCrxO10-δ: without chromate doping, a mixture of...

Numerical simulations of river bed dynamics for the South Saskatchewan River, Canada

P. Ashworth, A. Nicholas, D. Parsons & G. Sambrook Smith
Data were generated to investigate the influence of bed roughness on the dynamics of large sand-bed rivers like the South Saskatchewan, Canada. The influence of roughness was investigated by using a numerical model to simulate the evolution of the river bed for a hypothetical sand-bed river modelled on the South Saskatchewan. The model generated information on the evolving river bed topography, water depth, flow velocities and sediment transport rates, over a period of 28 years...

Data from: Tracing the patterns of non-marine turtle richness from Triassic–Palaeogene: from origin through global spread

Terri Cleary, Roger Benson, Patricia Holroyd & Paul Barrett
Turtles are key components of modern vertebrate faunas and it is predicted that their diversity and distributions will be affected by anthropogenic climate change. Despite this, few studies have attempted to provide baseline data on turtle taxonomic richness through time or assess their past responses to global environmental change. We used the extensive Triassic–Palaeogene (252–23 Ma) fossil record of terrestrial and freshwater turtles to investigate diversity patterns, finding substantial variation in richness through time and...

Sales, Erika R. Manuli, Julien Thézé, Luiz Almeida, Mariane T. Menezes, Carolina M. Voloch, Marcilio J. Fumagalli, Thaís M. Coletti, Camila A. M. Da Silva, Mariana S. Ramundo, Mariene R. Amorim, Henrique H. Hoeltgebaum, Swapnil Mishra, Mandev S. Gill, Luiz M. Carvalho, Lewis F. Buss … & Nuno R. Faria
Brazil currently has one of the fastest growing SARS-CoV-2 epidemics in the world. Owing to limited available data, assessments of the impact of non-pharmaceutical interventions (NPIs) on virus spread remain challenging. Using a mobility-driven transmission model, we show that NPIs reduced the reproduction number from >3 to 1–1.6 in São Paulo and Rio de Janeiro. Sequencing of 427 new genomes and analysis of a geographically representative genomic dataset identified >100 international virus introductions in Brazil....

Data from: Ten more years of discovery: revisiting the quality of the sauropodomorph dinosaur fossil record

Daniel Cashmore, Philip Mannion, Paul Upchurch & Richard Butler
Spatiotemporal changes in fossil specimen completeness can bias our understanding of a group’s evolutionary history. The quality of the sauropodomorph fossil record was assessed a decade ago, but the number of valid species has since increased by 60%, and 17% of the taxa from that study have since undergone taxonomic revision. Here, we assess how 10 years of additional research has changed our outlook on the group’s fossil record. We quantified the completeness of all...

Data from: Varietal variation and chromosome behaviour during meiosis in Solanum tuberosum

Anushree Choudhary, Liam Wright, Olga Patricia Ponce, Jing Chen, Ankush Prashar Prashar, Eugenio Sanchez-Moran, Zewei Luo & Lindsey Compton
Naturally occurring autopolyploid species such as the autotetraploid potato Solanum tuberosum face a variety of challenges during meiosis. These include proper pairing, recombination and correct segregation of multiple homologous chromosomes, which can form complex multivalent configurations at metaphase I, and in turn alter allelic segregation ratios through double reduction. Here, we present a reference map of meiotic stages in diploid and tetraploid S. tuberosum using fluorescence in situ hybridisation (FISH) to differentiate individual meiotic chromosomes...

Redescription of the cranial skeleton of the Early Devonian (Emsian) sarcopterygian Durialepis edentatus Otto, 2007 (Dipnomorpha; Porolepiformes)

Sam Giles, Jorge Mondéjar-Fernández & Matt Friedman
Porolepiforms represent a clade of Devonian stem lungfishes, divided into the cosmine-bearing and likely paraphyletic ‘Porolepidae’ (e.g., Porolepis, Heimenia) and the cosmine-free and stratigraphically younger Holoptychiidae (e.g., Holoptychius, Glyptolepis, Laccognathus). Data on the dermoskeleton are available for both groups, but are more limited for ‘porolepids’. Here we present new information on the ‘porolepid’ Durialepis edentatus from the Emsian (Early Devonian) of Germany based on micro-CT scanning. The material comprises an articulated skull of a single...

Early Silurian chondrichthyans from the Tarim Basin (Xinjiang, China)

Plamen Andreev, Wenjin Zhao, Nian-Zhong Wang, Moya Smith, Li Qiang, Xindong Cui, Min Zhu & Ivan Sansom
The Sinacanthida ordo nov. and Mongolepidida are spine- and scale-based taxa whose remains encompass some of the earliest reported fossils of chondrichthyan fish. Investigation of fragmentary material from the Early Silurian Tataertag and Ymogantau Formations of the Tarim Basin (Xinjiang Uygur Autonomous Region, China) has revealed a diverse mongolepidid and sinacanthid fauna dominated by mongolepids and sinacanthids in association with abundant dermoskeletal elements of the endemic ‘armoured’ agnathans known as galeaspids. Micro-computed tomography, scanning electron...

Palms and trees resist extreme drought in Amazon forests with shallow water tables

Thaiane Sousa, Juliana Schietti, Fernanda Coelho De Souza, Adriane Esquivel-Muelbert, Igor Ribeiro, Thaise Emilio, Pedro Pequeno, Oliver Phillips & Flavia Costa
1. The intensity and frequency of severe droughts in the Amazon region has increase in recent decades. These extreme events are associated with changes in forest dynamics, biomass and floristic composition. However, most studies of drought response have focused on upland forests with deep water tables, which may be especially sensitive to drought. Palms, which tend to dominate the less well-drained soils, have also been neglected. The relative neglect of shallow water tables and palms...

Fossil microbodies are melanosomes: evaluating and rejecting the ‘fossilised decay-associated microbes’ hypothesis

Arindam Roy, Christopher Rogers, Thomas Clements, Michael Pittman, Olivier Habimana, Martin Peter & Jakob Vinther
Melanosomes are membrane-bound organelles of varying geometry, commonly found within a range of vertebrate tissues, that contain the pigment melanin. Melanosomes have been identified in the fossil record in many exceptionally preserved fossils allowing reconstructions of the coloration of many extinct animals. However, these microstructures have also been interpreted as “microbial cells” or melanin producing bacteria based on their geometric similarities to melanosomes. Here we test these two conflicting hypotheses experimentally. Our results demonstrate multiple...
