Edizione critica digitale del codice noto come Codice Pelavicino conservato presso l’Archivio Capitolare Lunense (Sarzana), manoscritto del XIII secolo, che contiene numerosi documenti dei secoli XI-XIII inerenti la Chiesa di Luni. Principale promotore della sua redazione fu il vescovo di Luni Enrico da Fucecchio, che salì al soglio episcopale nel 1273 e resignò la carica tra il 24 ottobre 1296 e l’inizio del 1297. Al fine di salvaguardare i beni e i diritti della Chiesa...

The extraterrestrial dust flux: size distribution and mass contribution estimates inferred from the Transantarctic Mountain (TAM) micrometeorite collection

Martin Suttle & Luigi Folco
This study explores the long-duration (0.8-2.3Ma), time-averaged micrometeorite flux (mass and size distribution) reaching Earth, as recorded by the Transantarctic Mountain (TAM) micrometeorite collection. We investigate a single sediment trap (TAM65), performing an exhaustive recovery and characterization effort and identifying 1643 micrometeorites (between 100-2000μm). Approximately 7% of particles are unmelted or scoriaceous, of which 75% are fine-grained. Among cosmic spherules, 95.6% are silicate-dominated S-types, and further subdivided into porphyritic (16.9%), barred olivine (19.9%), cryptocrystalline (51.6%)...

Phylogenetic relatedness mediates persistence and density of soil seed banks

Margherita Gioria, Petr Pyšek, Carol Baskin & Angelino Carta
Soil seed banks can strongly affect survival and expansion of plant populations by spreading mortality risks and distributing genetic diversity through time. Knowledge of the main factors regulating the ability of seeds to persist in the soil beyond the first growing season is however limited. While morphological and physiological seed traits, and the degree of environmental uncertainty are considered important in shaping the seed-banking strategies of plants, global assessments that explicitly account for phylogenetic relatedness...

Christos Dadousis, Francesca Cecchi, Michela Ablondi, Maria Chiara Fabbri, Alessandra Stella & Riccardo Bozzi
The objective of this study was to investigate the genetic diversity of the Garfagnina (GRF) goat, a breed that currently risks extinction. For this purpose, 48 goats were genotyped with the Illumina CaprineSNP50 BeadChip and analyzed together with 214 goats belonging to 9 other Italian breeds (~25 goats/breed) from the AdaptMap project [Argentata (ARG), Bionda dell’Adamello (BIO), Ciociara Grigia (CCG), Di Teramo (DIT), Garganica (GAR), Girgentana (GGT), Orobica (ORO), Valdostana (VAL) and Valpassiria (VSS)]. Comparative...

Diurnal timing of nonmigratory movement by birds: the importance of foraging spatial scales

Julie Mallon, Marlee Tucker, Annalea Beard, , Keith Bildstein, Katrin Böhning-Gaese, John Brzorad, Evan Buechley, Javier Bustamante, Carlos Carrapato, José Castillo-Guerrero, Elizabeth Clingham, Mark Desholm, Christopher DeSorbo, Robert Domenech, Hayley Douglas, Olivier Duriez, Peter Enggist, Nina Farwig, Wolfgang Fiedler, Anna Gagliardo, Clara García-Ripollés, Juan Antonio Gil, Morgan Gilmour, Roi Harel … & Bill Fagan
Timing of activity can reveal an organism’s efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of timing of movement activity among species using six temporal variables: start of activity relative to sunrise, end of activity relative to...

Analysis of RNA-seq, DNA target enrichment, and Sanger nucleotide sequence data resolves deep splits in the phylogeny of cuckoo wasps (Hymenoptera: Chrysididae)

Thomas Pauli, Karen Meusemann, Sandra Kukowka, Manuela Sann, Alexander Donath, Christoph Mayer, Jan Philip Oeyen, Yolanda Ballesteros, Alexander Berg, Eric Van Den Berghe, Hermes Escalona, Adalgisa Guglielmino, Manfred Niehuis, Massimo Olmi, Lars Podsiadlowski, Carlo Polidori, Jeroen De Rond, Paolo Rosa, Thomas Schmitt, Franco Strumia, Mareike Wurdack, Shanlin Liu, Xin Zhou, Bernhard Misof, Ralph Peters … & Oliver Niehuis
The wasp family Chrysididae (cuckoo wasps, gold wasps) comprises exclusively parasitoid and kleptoparasitic species, many of which feature a stunning iridescent coloration and phenotypic adaptations to their parasitic life style. Previous attempts to infer phylogenetic relationships among the family’s major lineages (subfamilies, tribes, genera) based on Sanger sequence data were insufficient to statistically resolve the monophyly and the phylogenetic position of the subfamily Amiseginae and the phylogenetic relationships among the tribes Allocoeliini, Chrysidini, Elampini, and...

Microbleeds, cerebral hemorrhage, and functional outcome after endovascular thrombectomy

Imad Derraz, Federico Cagnazzo, Nicolas Gaillard, Riccardo Morganti, Cyril Dargazanli, Raed Ahmed, Pierre-Henri Lefevre, Carlos Riquelme, Isabelle Mourand, Gregory Gascou, Alain Bonafe, Caroline Arquizan & Vincent Costalat
Objective—To determine whether the presence, number, and distribution of cerebral microbleeds (CMBs) on pretreatment MRI scans are associated with an increased risk of intracerebral hemorrhage (ICH) or poor functional outcome following endovascular thrombectomy (EVT) for acute ischemic stroke (AIS). Methods—We analyzed prospectively collected data of consecutive patients treated by EVT for AIS, in a comprehensive stroke center where MRI is the first-line pretreatment imaging. Neuroradiologists blinded to clinical data rated CMBs on T2* sequence using...

Supplementary material for Roca-Neyra Equids: Late Miocene to Early Pleistocene Hipparion - Equus database for multivariate and statistical analysis for European fossil Equids

Omar Cirilli, Raymond Louis Bernor & Lorenzo Rook
We undertake a redescription of the equid sample from the early Pleistocene of Roca – Neyra, France. This locality has been recently calibrated at the Pliocene/Pleistocene boundary (2.6 ± 0.2 Ma) and therefore it is of interest for the first appearance of the genus Equus and last appearance of hipparionine horses. The Roca – Neyra equid sample, re – analyzed herein using morphological, morphometrical and statistical analyses, has revealed the co – occurrence of Plesiohipparion...

Data from: Nasal compartmentalization in Kogiidae (Cetacea, Physeteroidea): Insights from a new late Miocene dwarf sperm whale from the Pisco Formation

Aldo Benites-Palomino, Jorge Velez-Juarbe, Alberto Collareta, Diana Ochoa, Ali Altamirano, Matthieu Carré, Manuel J. Laime, Mario Urbina & Rodolfo Salas-Gismondi
Facial compartmentalization in the skull of extant pygmy whales (Kogiidae) is a unique feature among cetaceans that allows the housing of a wide array of organs responsible for echolocation. Recent fossil findings depict a remarkable disparity of the facial bone organization in Miocene kogiids, but the significance of such a rearrangement for the evolution of the clade has been barely explored. Here we describe Kogia danomurai sp. nov., a late Miocene (ca. 5.8 Ma) taxon...

Imaging of the vulnerable carotid plaque: role of imaging techniques and a research agenda

Iacopo Fabiani, Carlo Palombo, Davide Caramella, Jan Nilsson & Raffaele De Caterina
Objectives: Atherothrombosis in the carotid arteries is a main cause of ischemic stroke, and may depend on plaque propensity to complicate with rupture or erosion, in turn related to qualitative features amenable to in vivo imaging. This would provide an opportunity for risk stratification and – potentially – local treatment of more “vulnerable” plaques. We here review current information on this topic. Methods: We systematically reviewed the literature for concepts derived from pathophysiological, histopathological and...

Data from: Climatic refugia boosted allopatric diversification in Western Mediterranean vipers

Fernando Martínez-Freiría, Inês Freitas, Marco A. L. Zuffi, Philippe Golay, Sylvain Ursenbacher & Guillermo Velo-Antón
Abstract: Aim: to understand the role of climate in fostering diversification, this study reconstructs the historical biogeography of Western Mediterranean vipers Location: Western Mediterranean Basin Taxon: Vipera aspis and V. latastei-monticola complex Methods: phylogeographic analyses were performed over mitochondrial (three genes) and nuclear sequences (two genes), extensively covering species ranges. A total of 4,056 records were assigned to genetic units, using interpolations of genetic data, to test phylogenetic niche conservatism, under a 3D hypervolume approach,...

Data from: A new small, mesorostrine inioid (Cetacea, Odontoceti, Delphinida) from four late Miocene localities of the Pisco Basin, Peru

Olivier Lambert, Alberto Collareta, Aldo Benites-Palomino, Claudio Di Celma, Christian De Muizon, Mario Urbina & Giovanni Bianucci
The moderately rich past diversity of the superfamily Inioidea (Cetacea, Odontoceti) in both the Atlantic and Pacific oceans contrasts with the present survival of a single genus (Inia, Amazon river dolphin, family Iniidae) in freshwater deposits of South America and of a single species (Pontoporia blainvillei, Franciscana, family Pontoporiidae) along the eastern coast of that continent. However, part of the late Miocene to Pliocene inioid fossil record is made of relatively fragmentarily known species, for...

Fast saccadic eye-movements in humans suggest that numerosity perception is automatic and direct.

Elisa Castaldi, David Burr, Marco Turi & Paola Binda
Fast saccades are rapid automatic oculomotor responses to salient and ecologically important visual stimuli such as animals and faces. Discriminating the number of friends, foe or prey may also have an evolutionary advantage. In this study participants were asked to saccade rapidly towards the more numerous of two arrays. Participants could discriminate numerosities with high accuracy and great speed, as fast as 190 ms. Intermediate numerosities were more likely to elicit fast saccades than very...
