Data from: Good parenting may not increase reproductive success under environmental extremesRebecca J. Fox, Megan L. Head & Iain Barber
For species exhibiting parental care, the way in which parents adjust care behaviour to compensate for environmental change potentially influences offspring survival and, ultimately, population viability. Using the three-spined stickleback (Gasterosteus aculeatus) – a species in which males provide parental care by building and tending a nest and fanning the eggs – we examined how low dissolved oxygen (DO) levels affect paternal care, embryo development and survival. While levels of nest tending were unaffected by...
Data from: A three-dimensionally preserved lobopodian from the Herefordshire (Silurian) Lagerstätte, UKDerek J. Siveter, Derek E.G. Briggs, David J. Siveter, Mark D. Sutton, David Legg & Derek E. G. Briggs
The Herefordshire (Silurian) Lagerstätte (c. 430 MYr BP) has yielded, amongst many exceptionally preserved invertebrates, a wide range of new genera belonging to crown-group Panarthropoda. Here we increase this panarthropod diversity with the lobopodian Thanahita distos, a new total-group panarthropod genus and species. This new lobopodian preserves at least nine paired, long, slender appendages, the anterior two in the head region and the posterior seven representing trunk lobopods. The body ends in a short post-appendicular...
Data from: Molecular insights into genome-wide association studies of chronic kidney disease-defining traitsXiaoguang Xu, James M. Eales, Artur Akbarov, Hui Guo, Lorenz Becker, David Talavera, Fezhan Ashraf, Jabran Nawaz, Sanjeev Pramanik, John Bowes, Xiao Jiang, John Dormer, Matthew Denniff, Andrzej Antczak, Monika Szulinska, Ingrid Wise, Priscilla R. Prestes, Maciej Glyda, Pawel Bogdanski, Ewa Zukowska-Szczechowska, Carlo Berzuini, Adrian S. Woolf, Nilesh J. Samani, Fadi J. Charchar & Maciej Tomaszewski
Genome-wide association studies (GWAS) have identified >100 loci of chronic kidney disease-defining traits (CKD-dt). Molecular mechanisms underlying these associations remain elusive. Using 280 kidney transcriptomes and 9958 gene expression profiles from 44 non-renal tissues we uncover gene expression partners (eGenes) for 88.9% of CKD-dt GWAS loci. Through epigenomic chromatin segmentation analysis and variant effect prediction we annotate functional consequences to 74% of these loci. Our colocalisation analysis and Mendelian randomisation in >130,000 subjects demonstrate causal...
Data from: Lysine-14 acetylation of histone H3 in chromatin confers resistance to the deacetylase and demethylase activities of an epigenetic silencing complexMingxuan Wu, Dawn Hayward, Jay H. Kalin, Yun Song, John W.R. Schwabe, Philip A. Cole & John WR Schwabe
The core CoREST complex (LHC) contains histone deacetylase HDAC1 and histone demethylase LSD1 held together by the scaffold protein CoREST. Here we analyze the purified LHC with modified peptide and reconstituted semisynthetic mononucleosome substrates. LHC demethylase activity toward methyl-Lys4 in histone H3 is strongly inhibited by H3 Lys14 acetylation, and this appears to be an intrinsic property of the LSD1 subunit. Moreover, the deacetylase selectivity of LHC unexpectedly shows a marked preference for H3 acetyl-Lys9...
Data from: Evolution of thermal tolerance in multifarious environmentsMaria Cuenca Cambronero, Jordan Beasley, Stephen Kissane & Luisa Orsini
Species extinction rates are many times greater than the direst predictions made two decades ago by environmentalists, largely because of human impact. Major concerns are associated with the predicted higher recurrence and severity of extreme events, such as heat waves. Although tolerance to these extreme events is instrumental to species survival, little is known whether and how it evolves in natural populations, and to what extent it is affected by other environmental stressors. Here, we...
Data from: A well-preserved respiratory system in a Silurian ostracodDavid J. Siveter, Derek E.G. Briggs, Derek J. Siveter, Mark D. Sutton & Derek E. G. Briggs
Ostracod crustaceans are diverse and ubiquitous in aqueous environments today but relatively few known species have gills. Ostracods are the most abundant fossil arthropods but examples of soft-part preservation, especially of gills, are exceptionally rare. A new ostracod, Spiricopia aurita (Myodocopa), from the marine Silurian Herefordshire Lagerstätte (430 Mya), UK, preserves appendages, lateral eyes and gills. The respiratory system includes five pairs of gill lamellae with hypobranchial and epibranchial canals that conveyed hemolymph. A heart...
Data from: A Tournaisian (earliest Carboniferous) conglomerate-preserved non-marine faunal assemblage and its environmental and sedimentological contextJennifer A. Clack, Carys E. Bennett, Sarah J. Davies, Andrew C. Scott, Janet E. Sherwin & Timothy R. Smithson
A conglomerate bed from the Tournaisian Ballagan Formation of Scotland preserves a rich array of vertebrate and other non-marine fossils providing an insight into the wider ecosystem and palaeoenvironment that existed during this pivotal stage of Earth history. It challenges hypotheses of a long-lasting post-extinction trough following the end-Devonian extinction event. The fauna recovered includes a wide size range of tetrapods, rhizodonts and dipnoans, from tiny juveniles or small-bodied taxa up to large adults, and...
Data from: A fish and tetrapod fauna from Romer’s gap preserved in Scottish Tournaisian floodplain depositsBenjamin K. A. Otoo, Jennifer A. Clack, Timothy R. Smithson, Carys E. Bennett, Timothy J. Kearsey & Michael I. Coates
The end‐Devonian mass extinction has been framed as a turning point in vertebrate evolution, enabling the radiation of tetrapods, chondrichthyans and actinopterygians. Until very recently ‘Romer's Gap’ rendered the Early Carboniferous a black box standing between the Devonian and the later Carboniferous, but now new Tournaisian localities are filling this interval. Recent work has recovered unexpected tetrapod and lungfish diversity. However, the composition of Tournaisian faunas remains poorly understood. Here we report on a Tournaisian...
