FAME: Software for analysing rock microstructures
2016
Determination of rock microstructures leads to a better understanding of the formation and deformation of polycrystalline solids. Here, we present FAME (Fabric Analyser based Microstructure Evaluation), an easy-to-use MATLAB®-based software for processing datasets recorded by an automated fabric analyser microscope. FAME is provided as a MATLAB®-independent Windows® executable with an intuitive graphical user interface. Raw data from the fabric analyser microscope can be automatically loaded, filtered and cropped before analysis. Accurate and efficient rock microstructure analysis is based on an advanced user-controlled grain labelling algorithm. The preview and testing environments simplif…
Complex geometry and kinematics of subsidiary faults within a carbonate-hosted relay ramp
2019
Abstract Minor fault geometry and kinematics within relay ramps is strongly related to the stress field perturbations that can be produced when two major fault segments overlap and interact. Here we integrate classical fieldwork and interpretation of a virtual outcrop to investigate the geometry and kinematics of subsidiary faults within a relay ramp along the Tre Monti normal fault in the Central Apennines. Although the Tre Monti fault strikes parallel to the regional extension (NE-SW) it shows predominant dip-slip kinematics, suggesting a NW-SE oriented extension acting at sub-regional scale (1–10 km). Conversely, the slickenlines collected on the front segment of the relay ramp highlight…
Unmanned Aerial Vehicle (UAV) Survey with Commercial-Grade Instruments: A Case Study from the Eastern Ḫabur Archaeological Survey, Iraq
2018
Low-altitude photography in archaeology is now common practice at the scale of excavations; however, landscape-scale applications are a relatively new endeavor with promising analytical potential. From 2014–2016, an unmanned aerial vehicle (UAV) with a mounted camera was used to document sites recorded as part of the Eastern Ḫabur Archaeological Survey (EḪAS), an archaeological reconnaissance project in western Dohuk Province, Iraqi Kurdistan. The EḪAS team documented over 70 archaeological sites with the UAV, from single-phase artifact scatters, to archaeological remains with standing architecture, to tells that cover more than 30 hectares. Representative examples from this survey are pres…
Paleogenetic and morphometric analysis of a Mesolithic individual from Grotta d'Oriente: An oldest genetic legacy for the first modern humans in Sici…
2020
Abstract Grotta d’Oriente, a coastal cave located on the island of Favignana (Sicily, Italy) is a key site for the study of the early human colonization of Sicily. Inside the cave, during different field excavations, three burials attributable to the Late Upper Palaeolithic and Mesolithic were found. The Mesolithic Oriente B individual, directly dated at 9,377 ± 25 uncal BP, was previously assigned to HV1 haplogroup using a traditional approach. However, it is well known that PCR based methods are prone to erroneous haplotype or haplogroup determination. In order to redefine the mitochondrial lineage of this Mesolithic hunter-gatherer and explore its phylogenetic position, we target-enriche…
Ammonoids and quantitative biochronology - A unitary association perspective
2015
Ammonoid evolutionary changes have long been recognized to be excellent time markers. They are the major macrofossil group to date and correlate Paleozoic and Mesozoic marine strata. Originations and extinctions of ammonoid species are commonly used to define GSSPs and build high resolution biozonations. Biochronology is now an advanced field with the recent development of computerized, quantitative methods yielding robust biochronological schemes. It has been demonstrated that such quantitative biochronological methods are very efficient to resolve (often complex) biostratigraphic contradictions and produce accurate and high resolution biozonations, thus enabling precise dating and correla…

100‐million‐year‐old ant–conifer associates inside French amber: a fortuitous or ecological association?
2020
International audience; Ants exhibit a plethora of ecological interactions with terrestrial plants. These interactions are broadly surveyed in modern ecosystems, but are much more difficult to unveil in the fossil record. Here, we report a unique ant–conifer association preserved in an opaque piece of 100‐million‐year‐old amber from Charentes in Western France, revealed by propagation phase‐contrast X‐ray synchrotron microtomography (PPC‐SRμCT). Most legs of the ant encircle the conifer twig, and the arthropod harbours a hooked position onto the leafy axis. The conifer is assigned to Glenrosa carentonensis Moreau, Néraudeau, Tafforeau and Dépré, whereas the ant is ascribed to Gerontoformica…
Classification of the European marsh vegetation (Phragmito‐Magnocaricetea) to the association level
2020
Aims: To create a comprehensive, consistent and unequivocal phytosociological classification of European marsh vegetation of the class Phragmito-Magnocaricetea. Location: Europe. Methods: We applied the Cocktail method to a European data set of 249, 800 vegetation plots. We identified the main purposes and attributes on which to base the classification, defined assignment rules for vegetation plots, and prepared formal definitions for all the associations, alliances and orders of the class Phragmito-Magnocaricetea using formal logic. Each formula consists of the combination of “functional species groups”, cover values of individual species, and in the case of high-rank syntaxa also of “disc…
Sulawesifulvius thailandicus – a new species of the genus Sulawesifulvius Gorczyca, Chérot & Štys from Thailand (Hemiptera, Heteroptera, Miridae, Cyl…
2017
Abstract A new species of the genus Sulawesifulvius, Sulawesifulvius thailandicus Wolski, Yasunaga & Gorczyca, sp. n., is described from Thailand. The present finding also represents the first distribution record in Indochina for the genus. Color adult habitus images for Sulawesifulvius thailandicus and Sulawesifulvius schuhi (type species of the genus), male genital drawings of Sulawesifulvius thailandicus, and scanning electron micrographs of selected structures of Sulawesifulvius schuhi and Sulawesifulvius thailandicus are provided.
A new species of the Genus Hemiophthalmocoris from the Oriental Region (Hemiptera: Heteroptera: Miridae: Cylapinae).
2016
Abstract This paper provides the second report of the Cylapinae genus Hemiophthalmocoris Poppius, 1912—H. raunoi sp. nov. outside the Afrotropical Region (Malaysia: Sabah). Scanning electron micrographs of selected structures of Hemiophthalmocoris lugubris Poppius, 1912 are presented. A photograph of the adult of H. raunoi sp. nov. and H. sulawesicus Gorczyca & Cherot, 2002 are given. Illustrations of the male genitalia and dorsal habitus drawing of H. raunoi sp. nov. are provided.
