Abstraction through the Merger of Iconic Elements in Forming New Allographs: The Logogram 539

Sven Gronemeyer
One contributor to the calligraphic complexity of Classic Maya writing is the ability afforded by the script to create allographs. There are examples with multiple stages of extraction and simplification to create allographs. In order to create a unique graph, distinctive parts of the feline WAY icon are merged into the well-known allograph with its right half covered in jaguar fur, although both allographs represent the very same sign.

Data from: Increased levels of perceived competition decrease juvenile kin-shoaling preferences in a cichlid fish

Timo Thünken, Saskia Hesse & Denis Meuthen
Inclusive fitness theory predicts that individuals can increase their indirect fitness by grouping with kin. However, kin-grouping also increases competition between kin, which potentially outweighs its benefits. The level of kin-competition is contingent on environmental conditions and thus highly variable. Hence, individuals should benefit from plastically adjusting kin-discrimination according to the expected level of kin competition. Here, we investigate whether perceived high competition affects juvenile kin-shoaling preferences in the cichlid Pelvicachromis taeniatus. Juveniles were given...

Data from: Structurally assisted super black in colorful peacock spiders

Dakota E. McCoy, Victoria E. McCoy, Nikolaj K. Mandsberg, Anna V. Shneidman, Joanna Aizenberg, Richard O. Prum & David Haig
Male peacock spiders (Maratus, Salticidae) compete to attract female mates using elaborate, sexually-selected displays. They evolved both brilliant color and velvety black. Here we use scanning electron microscopy (SEM), hyperspectral imaging, and finite-difference time-domain (FDTD) optical modeling to investigate the deep black surfaces of peacock spiders. We found that super black regions reflect <0.5% of light (for a 30° collection angle) in Maratus speciosus (0.44%) and Maratus karrie (0.35%) due to microscale structures. Both species...

Data from: Resolution of the ordinal phylogeny of mosses using targeted exons from organellar and nuclear genomes

Yang Liu, Matthew G. Johnson, Cymon J. Cox, Rafael Medina, Nicolas Devos, Alain Vanderpoorten, Lars Hedenäs, Neil E. Bell, James R. Shevock, Blanka Aguero, Dietmar Quandt, Norman J. Wickett, A. Jonathan Shaw & Bernard Goffinet
Mosses are a highly diverse lineage of land plants, whose diversification, spanning at least 400 million years, remains phylogenetically ambiguous due to the lack of fossils, massive early extinctions, late radiations, limited morphological variation, and conflicting signal among previously used markers. Here, we present phylogenetic reconstructions based on complete organellar exomes and a comparable set of nuclear genes for this major lineage of land plants. Our analysis of 142 species representing 29 of the 30...

Data from: Systematics and macroevolution of extant and fossil scalopine moles (Mammalia, Talpidae)

Achim H. Schwermann, Kai He, Benjamin J. Peters, Thorsten Plogschties & Gabriele Sansalone
Scalopini is one of the two fully fossorial mole tribes in the family Talpidae, with remarkable adaptations to subterranean lifestyles. Most living Scalopini species are distributed in North America while a sole species occurs in China. On the other hand, scalopine fossils are found in both Eurasia and North America from upper Oligocene strata onwards, implying a complex biogeographical history. The systematic relationships of both extant and fossil Scalopini across North America and Eurasia are...

Data from: Palaeobiogeography and evolutionary patterns of the larger foraminifer Borelis de Montfort (Borelidae)

Davide Bassi, Juan Carlos Braga, Giovanni Di Domenico, Johannes Pignatti, Sigal Abramovich, Pamela Hallock, Janine Koenen, Zoltan Kovacs, Martin R. Langer, Giulio Pavia & Yasufumi Iryu
The palaeobiogeography of the alveolinoid Borelis species reveals the evolutionary patterns leading to the two extant representatives, which occur in shallow-water tropical carbonate, coral reef-related settings. Type material and new material of fossil Borelis species, along with Recent specimens were studied to assess their taxonomic status, species circumscriptions (based on proloculus size, occurrence of Y-shaped septula, and the index of elongation), palaeobiogeography and evolutionary dynamics. The species dealt with here are known from exclusively fossil...

Data from: Expression of matrix Metalloproteinases-2 and aquaporin-1 in corneoscleral junction after angle-closure in rabbits

Yaqin Jiang, Canwei Zhang, Jianli Ma, Luping Wang, Jing Gao, Jiantao Ren, Wei He, Sheng Wang, Shuai Sheng & Xudong Huang
Background: To investigate the expression of Matrix Metalloproteinases 2 and aquaporin-1 in corneoscleral junction and explore the mechanism of trabecular damageafter angle-closure. Methods: Thirty New Zealand white rabbits were randomly assigned into 2 groups, theexperimental group (Group 1) including twenty five rabbits and the control group (Group 2) including 5 rabbits. The rabbits in the experimental group were used to establish angle-closure models, and the rabbits in the control group were not subjected to any...

Data from: Frequency and characteristics of MODY 1 (HNF4A mutation) and MODY 5 (HNF1B mutation) - Analysis from the DPV database

Katharina Warncke, Sebastian Kummer, Klemens Raile, Jürgen Grulich-Henn, Joachim Woelfle, Elisabeth Steichen, Nicole Prinz & Reinhard W. Holl
Objective. To characterize initial presentation and clinical course of patients with hepatocyte nuclear factor (HNF) 4A- and HNF1B-MODY in a multinational registry. Design, setting and participants. Within the Diabetes Patienten Verlaufsdokumentation (DPV) registry, 44 patients with HNF4A- and 35 patients with HNF1B-MODY were characterized and compared with patients < 20years old with type 1 diabetes (T1D)/type 2 diabetes (T2D). Main outcome measure. Clinical and laboratory parameters, therapy, metabolic control, and extrapancreatic symptoms in patients with...

Data from: Diversity and evolution of the transposable element repertoire in arthropods with particular reference to insects

Malte Petersen, David Armisén, Richard Gibbs, Lars Hering, Abderrahman Khila, Georg Mayer, Stephen Richards, Oliver Niehuis & Bernhard Misof
Background: Transposable elements (TEs) are a major component of metazoan genomes and are associated with a variety of mechanisms that shape genome architecture and evolution. Despite the ever-growing number of insect genomes sequenced to date, our understanding of the diversity and evolution of insect TEs remains poor. Results: Here, we present a standardized characterization and an order-level comparison of arthropod TE repertoires, encompassing 62 insect and 11 outgroup species. The insect TE repertoire contains TEs...

Data from: Effect of epistasis and environment on flowering time of barley reveals novel flowering-delaying QTL allele

Nazanin Pesaran Afsharyan, Wiebke Sannemann, Jens Léon & Agim Ballvora
Flowering time is a complex trait and has key role in crop yield and adaptation to environmental stressors such as heat and drought. The aim of this study was to better understand interconnected dynamic of epistasis and environment and look for novel regulators. For this purpose we investigated 534 spring barley MAGIC DH lines for flowering time at various environments. Analysis of QTL, epistatic interaction, QTL × environment (Q×E) and epistasis × environment (E×E) interactions...

Data from: Shape variability in tridactyl dinosaur footprints: the significance of size and function

Jens N. Lallensack, Thomas Engler & H. Jonas Barthel
The functional anatomy of the hindlimb of bipedal dinosaurs has been intensively studied. Yet, surprisingly little work has been done concerning functional adaptations in the digits for terrestrial locomotion. While complete and articulated pes skeletons are scarce, pes shape is abundantly recorded by fossil footprints. Here we aim to elucidate the significance of footprint shape and size for locomotion using a large sample (n = 303) of tridactyl dinosaur footprints from a broad range of...

The expansion and diversification of pentatricopeptide repeat RNA editing factors in plants

Ian Small, Bernard Gutmann, Santana Royan, Mareike Schallenberg-Rüdinger, Henning Lenz, Ian Castleden, Rose McDowell, Michael Vacher, Julian Tonti-Filippini, Charles Bond & Volker Knoop
The RNA-binding pentatricopeptide repeat (PPR) family comprises hundreds to thousands of genes in most plants, but only a few dozen in algae, evidence of massive gene expansions during land plant evolution. The nature and timing of these expansions has not been well-defined due to the sparse sequence data available from early-diverging land plant lineages. We exploit the comprehensive OneKP dataset of over 1,000 transcriptomes from diverse plants and algae to establish a clear picture of...
