    Repression, rivalry and racketeering in the creation of Franco’s Spain: the curious case of Emilio Griffiths

    Get PDF
    This article charts the personal history of Emilio Griffiths Navarro, a key individual in the Francoist administration in the Campo de Gibraltar (Cádiz province) during the early months of the Spanish Civil War. Griffiths is used as a case study to analyse the dynamics of Francoist repression in Southern Spain, and in particular the construction of what Rúben Serém has referred to as the ‘kleptocratic state’ that Franco’s fellow conspirator, General Queipo de Llano, constructed in the South. The article reaffirms the degree to which personal networks, personal rivalries and personal gain played a role in the Francoist repression. As a local case study, it also notes the unique conditions provided by rebel Spain’s border with British Gibraltar, and how this shaped the nature and extent of that repression. The article charts Griffiths’ own demise, from senior rebel official to arrest and unexplained death at the hands of Francoist security forces just ten months later, and uses the mystery to further speculate as to rivalries and repression in early-Francoist Spai

    Spain’s Partido Popular government is reverting to Francoist type over Gibraltar, to the detriment of all.

    Tensions have risen between Spain and Gibraltar following the implementation of additional border checks between the two territories by the Spanish government. Gareth Stockey notes that border restrictions are likely to have a damaging effect on both Gibraltar and neighbouring Spanish communities. He argues that the Spanish government’s actions represent a break from the conciliatory stance pursued by the previous Zapatero government, and are more in keeping with the traditional ‘Francoist’ approach of using the Gibraltar issue to divert public and media attention away from domestic problems

    Endocranial Morphology of the Extinct North American Lion (Panthera atrox)

    The extinct North American lion (Panthera atrox) is one of the largest felids (Mammalia, Carnivora) to have ever lived, and it is known from a plethora of incredibly well-preserved remains. Despite this abundance of material, there has been little research into its endocranial anatomy. CT scans of a skull of P. atrox from the Pleistocene La Brea Tar pits were used to generate the first virtual endocranium for this species and to elucidate previously unknown details of its brain size and gross structure, cranial nerves, and inner-ear morphology. Results show that its gross brain anatomy is broadly similar to that of other pantherines, although P. atrox displays less cephalic flexure than either extant lions or tigers, instead showing a brain shape that is reminiscent of earlier felids. Despite this unusual reduction in flexure, the estimated absolute brain size for this specimen is one of the largest reported for any felid, living or extinct. Its encephalization quotient (brain size as a fraction of the expected brain mass for a given body mass) is also larger than that of extant lions but similar to that of the other pantherines. The advent of CT scans has allowed nondestructive sampling of anatomy that cannot otherwise be studied in these extinct lions, leading to a more accurate reconstruction of endocranial morphology and its evolution

    The Fossil Record of Basal Monocots

    Get PDF
    The fossil record of basal monocots (Acorales and Alismatales) extends back to the Cretaceous in the Northern Hemisphere. While many fossils were originally assigned to these basal groups, rigorous paleobotanical studies show many of them to be misidentified. Acarus fossils have been reliably reported from the Eocene while those of Alismatales extend back to the early Cretaceous. The fossil record of basal monocots is usually represented by leaves, fruits, and seeds; however, some localities preserve stems with attached leaves and roots and even whole plants. A detailed examination of leaf venation patterns in alismatids has recently allowed the description of a new taxon from the Upper Cretaceous of Alberta based on leaves attributed to Limnocharitaceae. Anatomically preserved alismatid petioles (Heleophyton helobiaeoides) and well-preserved flowers/fruits are known from the Middle Eocene Princeton chert of British Columbia. A complete developmental sequence from flower to fruit is known, and this material has good possibilities for whole plant reconstruction. The extinct floating aquatic Limnobiophyllum (Araceae/Lemnoideae) and the genus Pistia have been the subject of morphological cladistic analyses and competing hypotheses of relationships among aroids and duckweeds. The fossil record and recent molecular studies support separate origins of Pistia and the duckweeds from within Araceae. The fossil taxon Pistia corrugata has been reexamined in light of new evidence and indicates the presence of a new genus that shows leaf morphology unlike that seen in extant Pistia, but with a similar growth habit. Fossil evidence indicates that the floating aquatic habit probably arose at least three times within Araceae

    Cuticular Features and Epidermal Patterns in the Genus Araucaria de Jussieu

    Get PDF
    This is the publisher's version, also available electronically from http://www.jstor.org.The cuticular organization and epidermal features of le aves from the four sections of the genus Araucaria, growing under similar environmental conditions, were studied by scanning electron microscopy. Cuticles from these extant species and the Jurassic fossil Araucarites santaecrucis were compared by rubber replicas and examination of the fossil leaf surfaces. Two distinct groups of araucarian leaves are distinguished by cuticular features. The Columbea-Bunya species have regular stomatal rows with polar cells always oriented in the same direction, four to five subsidiary cells, and a granular inner cuticle surface on both epidermal and subsidiary cells. The Eutacta-Intermedia species have four to seven subsidiary cells with thin cuticular flanges between guard cells and subsidiary cells, a smooth inner cuticular surface on both epidermal and subsidiary cells, and thinner intercellular flanges on epidermal cell walls. Epidermal features of a raucarian leaves appear to be taxonomically useful at the section level

    Last Stand? The Criminal Responsibility of War Veterans Returning from Iraq and Afghanistan with Posttraumatic Stress Disorder

    Get PDF
    As more psychologically scarred troops return from combat in Iraq and Afghanistan, society\u27s focus on and concern for these troops and their psychological disorders has increased With this increase and with associated studies confirming the validity of the Posttraumatic Stress Disorder (PTSD) diagnosis and the genuine impact of PTSD on the behavior of war veterans, greater weight may be given to the premise that PTSD is a mental disorder that provides grounds for a mental status defense, such as insanity, a lack of mens rea, or self-defense. Although considerable impediments remain, given the current political climate, Iraq and Afghanistan War veterans are in a better position to succeed in these defenses than Vietnam War veterans were a generation ago. This Article explores the prevalence and impact of PTSD, particularly in war veterans, the relevance of this disorder to the criminal justice system, and the likely evolution of related mental status defenses as Iraq and Afghanistan War veterans return from combat

    Seed cone anatomy of cheirolepidiaceae (coniferales): Reinterpreting pararaucaria patagonica wieland

    Get PDF
    • Premise of the study: Seed cone morphology and anatomy reflect some of the most important changes in the phylogeny and evolutionary biology of conifers. Reexamination of the enigmatic Jurassic seed cone Pararaucaria patagonica reveals previously unknown systematically informative characters that demonstrate affinities with the Cheirolepidiaceae. This paper documents, for the first time, internal anatomy for seed cones of this important extinct Mesozoic conifer family, which may represent the ghost lineage leading to modern Pinaceae. • Methods: Morphology and anatomy of cones from the Jurassic La Matilde Formation in Patagonia are described from a combination of polished wafers and thin section preparations. New photographic techniques are employed to reveal histological details of thin sections in which organic cell wall remains are not preserved. Specific terminology for conifer seed cones is proposed to help clarify hypotheses of homology for the various structures of the cones. • Key results: Specimens are demonstrated to have trilobed ovuliferous scale tips along with a seed enclosing pocket of ovuliferous scale tissue. Originally thought to represent a seed wing in P. patagonica, this pocket-forming tissue is comparable to the flap of tissue covering seeds of compressed cheirolepidiaceous cones and is probably the most diagnostic character for seed cones of the family. • Conclusions: Pararaucaria patagonica is assigned to Cheirolepidiaceae, documenting anatomical features for seed cones of the family and providing evidence for the antiquity of pinoid conifers leading to the origin of Pinaceae. A list of key morphological and anatomical characters for seed cones of Cheirolepidiaceae is developed to facilitate assignment of a much broader range of fossil remains to the family. This confirms the presence of Cheirolepidiaceae in the Jurassic of the Southern Hemisphere, which was previously suspected from palynological records.Fil: Escapa, Ignacio Hernán.

    Studies of Paleozoic Seed Ferns: Additional Studies of Microspermopteris aphyllum Baxter

    Get PDF
    This is the publisher's version, also available electronically from http://www.jstor.org.The genus Microspermopteris is characterized as a small lyginopterid pteridosperm with a pentarch protostele, irregular cortical ridges, and multicellular trichomes. We describe the frond architecture and variability among axillary branches previously unknown for the genus. Fronds are small and delicate, exhibiting three orders of branching. Clasping V-shaped petioles produce primary pinnae alternately to suboppositely from adaxial projections. Primary pinnae in turn produce secondaries that bear two-, three-, or four-lobed ultimate laminar pinnules. Pinnules reconstructed from serial sections are morphologically similar to Sphenopteris-like compressions; however, the overall frond is reduced in size and complexity. While some axillary branches produce secondary xylem, others are composed entirely of primary tissues. Some axillary branches produce scalelike leaves in a tight helix; distally, immature buds are surrounded by flattened bud scales. Although Microspermopteris shows similarities to Heterangium in stelar and cortical anatomy, the two taxa are distinct. Microspermopteris is interpreted as a delicate, scrambling vine, liana, or shrublike plant in contrast to the more robust lyginopterids Lyginopteris, Schopfiastrum, and Heterangium

    Pararaucaria delfueyoi sp. nov. from the late jurassic canadon calcareo formation, chubut, Argentina: Insights into the evolution of the cheirolepidiaceae

    Get PDF
    The discovery of 16 cylindrical conifer seed cones at the Estancia Vilan locality in the Late Jurassic Canadon Calcreo Formation of Chubut Province, Patagonia, Argentina, provides anatomically preserved specimens, allowing for the description of a second species of Pararaucaria (Cheirolepidiaceae). The new species, Pararaucaria delfueyoi, is similar in general features to the type species, Pararaucaria patagonica, but has a specifically diagnostic combination of characters that include cone size, seed number, features of histology, and seed size. Specimens are cylindrical with a narrow axis that bears helically arranged bract/scale complexes. The bract and scale diverge from the axis at ;90° and separate from each other almost immediately. The ovuliferous scale extends toward the margin of the cone and then arches over to enclose two inverted nonwinged seeds within a pocket of tissue. Although the specimens are abraded such that the distal regions of the ovuliferous scales are not preserved, this combination of morphological and histological characters allows for the assignment of P. delfueyoi to the Cheirolepidiaceae with confidence. The co-occurrence of this cone with an undescribed species of Araucaria extends the geographic and stratigraphic ranges of this association, which previously has been known only from the Middle Jurassic of Santa Cruz Province of Patagonia. This extends the knowledge of anatomical variation among seed cones of Cheirolepidiaceae and improves our understanding of homology relationships for conifer seed cone structures.Fil: Escapa, Ignacio Hernan.
