(Australian Centre for Neutron Scattering) ; Peretti, Adolf (Peretti Museum Foundation) ; Evans, Susan E. (University College London. Department of Cell and Developmental Biology)
Oculudentavis khaungraae was described based on a tiny skull trapped in amber. The slender tapering rostrum with retracted narial openings, large eyes, and short vaulted braincase led to its identification as the smallest avian dinosaur on record, comparable to the smallest living hummingbirds.

11 p, 1.9 MB Species-Specific Differences in Sperm Chromatin Decondensation Between Eutherian Mammals Underlie Distinct Lysis Requirements / Ribas-Maynou, Jordi (Universitat de Girona.

Departament de Biologia Cel·lular)
Sperm present a highly particular DNA condensation that is acquired during their differentiation. Protamines are key elements for DNA condensation. However, whereas the presence of protamine 1 (P1) is conserved across mammalian species, that of protamine 2 (P2) has evolved differentially, existing only few species that use both protamines for sperm DNA condensation.

In this paper we argue that ecological evolutionary developmental biology (ecoevo-devo) accounts of cognitive modernity are compatible with cultural evolution theories of language built upon iterated learning models. [...]

The life history of European Middle Pleistocene equids : first insights from bone histology / Nacarino Meneses, Carmen (Institut Català de Paleontologia Miquel Crusafont) ; Orlandi Oliveras, Guillem (Institut Català de Paleontologia Miquel Crusafont)
Evolutionary trends in body size are a central issue of study in Palaeontology. However, and despite body size being one of the most important life history traits of an animal, iconic size-decrease trends such as the one experienced by Equus during the European Pleistocene have never been analysed under a life history framework.

Institut de Recerca en Biomedicina) ; Ventura, Salvador (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular
A disordered to β-sheet transition was thought to drive the functional switch of Q/N-rich prions, similar to pathogenic amyloids. However, recent evidence indicates a critical role for coiled-coil (CC) regions within yeast prion domains in amyloid formation. [...]

ICEMASA) ; Lotze, Heike K. (Dalhousie University. Department of Biology)
Climate change effects on marine ecosystems include impacts on primary production, ocean temperature, species distributions, and abundance at local to global scales. These changes will significantly alter marine ecosystem structure and function with associated socio-economic impacts on ecosystem services, marine fisheries, and fishery-dependent societies. [...]

A new Iberian pleurosternid (Jurassic-Cretaceous transition, Spain) and first neuroanatomical study of this clade of stem turtles / Pérez-García, Adán (Universidad Nacional de Educación a Distancia. Grupo de Biología Evolutiva) ; Martín-Jiménez, Marcos (Universidad Nacional de Educación a Distancia. Grupo de Biología Evolutiva) ; Aurell, Marcos (Universidad de Zaragoza. Grupo Aragosaurus-IUCA) ; Canudo, José Ignacio (Universidad de Zaragoza. Grupo Aragosaurus-IUCA) ; Castanera, Diego (Institut Català de Paleontologia Miquel Crusafont)
A partial skeleton of a pleurosternid turtle (Paracryptodira), from the Jurassic-Cretaceous transition at the Spanish locality of Ágreda (Moncayo Region, Soria Province), is presented here. Its partial skull represents the third of this lineage to be recognised in the European record, with the previously known specimens corresponding to British species. [...]

Background: Sterols are structural and functional components of eukaryotic cell membranes. Plants produce a complex mixture of sterols, among which β-sitosterol, stigmasterol, campesterol, and cholesterol in some Solanaceae, are the most abundant species. [...]

13 p, 1.6 MB AMPA receptor auxiliary subunits emerged during early vertebrate evolution by neo/subfunctionalization of unrelated proteins / Ramos-Vicente, David (Institut d'Investigació Biomèdica Sant Pau) ; Bayés, Àlex (Institut d'Investigació Biomèdica Sant Pau) ; Universitat Autònoma de Barcelona
In mammalian synapses, the function of ionotropic glutamate receptors is critically modulated by auxiliary subunits. Most of these specifically regulate the synaptic localization and electrophysiological properties of AMPA-type glutamate receptors (AMPARs). [...]

17 p, 1.7 MB Red-Light Irradiation of Horse Spermatozoa Increases Mitochondrial Activity and Motility through Changes in the Motile Sperm Subpopulation Structure / Catalán, Jaime (Universitat de Girona.

Departament de Medicina i Cirurgia Animals) ; Mateo-Otero, Yentel (Universitat de Girona. Departament de Biologia) ; Rodríguez Gil, Joan Enric (Universitat Autònoma de Barcelona. Departament de Medicina i Cirurgia Animals) ; Miró, Jordi (Universitat Autònoma de Barcelona. Departament de Medicina i Cirurgia Animals) ; Yeste Oliveras, Marc (Universitat de Girona. Departament de Biologia)
Previous studies in other mammalian species have shown that stimulation of semen with red-light increases sperm motility, mitochondrial activity, and fertilizing capacity. This study sought to determine whether red-light stimulation using a light emitting diode (LED) at 620-630 nm affects sperm motility and structure of motile subpopulations, sperm viability, mitochondrial activity, intracellular ATP levels, rate of O consumption and DNA integrity of horse spermatozoa.
