    Description: Following Milankovitch's theory the incoming insolation or summer energy at 65°N is typically analysed to predict the waxing or waning of land ice. We here use a model-based deconvolution of the LR04 benthic-d18O stack into land ice distribution (de Boer et al., 2014, Köhler et al., 2015) to verify if the latitudinal focal point of land ice dynamics has changed over the last 2 Myr or whether this choice of 65°N in orbital data is indeed well justified. We find that the 5°-latitudinal band which contributes most to land ice albedo radiative forcing (ΔR_[LI]) is 70-75°N between 2.0-1.5 Myr, which is then until 1.0 Myr gradually substituted by 65-70°N. During the last 1 Myr both 60-65°N and 65-70°N dominate ΔR_[LI] and contribute approximately the same amount, while the relative importance of 70-75°N is shrinking. Our analyses illustrates that the choice of 65°N seems for the last 1 Myr to be well justified, while for earlier parts of the last 2 Myr the dominant land ice changes seems to happen up to 10° further to the north. Focusing on the last 800 kyr (the time for which precise data on atmospheric CO2 concentration exists) we furthermore find that the multi-millennial land ice growth and proxy-based reconstruction of global cooling (= the glaciation) appear synchronously to each other and to decreasing obliquity, but diverge from CO2. This suggests that the global cooling associated with Earth's way into an ice age as deduced in the reconstructions has to be mainly caused by the land ice albedo feedback, and is not dominated by the CO2 greenhouse forcing. One way of perceiving this CO2-glaciation divergence in reconstructions is that the reduced incoming insolation at high latitudes causes land ice growth and cooling, while there is a coexisting process that keeps CO2 at a relatively constant level. Solid Earth modeling experiments have indicated that falling sea level might lead to enhanced magma and CO2 production at mid-ocean ridges. Hasenclever et al. (2017) suggested that the combination of marine volcanism at mid-ocean ridges and at hot spot island volcanoes might react to decreasing sea level and be a potential cause for this CO2-glaciation divergence. This CO2-glaciation divergence needs to be considered, when using paleo data to quantify paleoclimate sensitivity: periods with diverging CO2 and global temperature change should be filtered out when approximating the relationship between global temperature rise and CO2 concentrations (Köhler et al., 2018).

    Description: The Gnassingbé clan has ruled the country since 1967. The demand for political alternance, initiated by institutional and electoral reforms, constituted the major contentious issue between the government and the challengers of the Gnassingbé regime throughout the survey period. An alliance of opposition parties and civil society groups organized peaceful demonstrations in opposition to the regime, which were often violently suppressed. Civil society organizations and representatives of the Christian church supported the demands of the opposition. The legislative elections of 20 December 2018, boycotted by the major opposition parties, resulted in an easy victory of the ruling party. The local elections, crucial for democratization at the grass-roots, but postponed time and again since 1987, were again postponed in December 2018 sine die. The human rights record of the government has improved but remains poor. Despite undeniable improvements to the framework and appearance of the regime's key institutions during the review period, democracy remains far from complete. However, the international community, notably Togo’s African peers, the AU and ECOWAS, followed a ‘laissez-faire’ approach in the interests of regional stability and their national interests in dealing with Togo. Economic growth remained stable at about 5% per annum. Public investment in infrastructure (e.g. roads, harbour) and increases in agricultural productivity, notably of export crops, had been the key drivers of economic growth. However, growth remains vulnerable to external shocks and the climate and has not been inclusive. Positive growth was overshadowed by increasing inter-personal and regional inequality as well as an increase in extreme poverty. Moreover, money-laundering, illegal money transfers and trafficking grew alarmingly. The business climate improved considerably nevertheless.
    Description: Author’s extended and up-dated version of ‘BTI 2020 – Togo Country Report’ (forthcoming)
    Description: RÉSUMÉ: Le clan Gnassingbé dirige le pays depuis 1967. La demande d'alternance politique, initiée par des réformes institutionnelles et électorales, a constitué le principal différend entre le gouvernement et les rivaux du régime de Gnassingbé tout au long de la période d'enquête. Une alliance de partis d'opposition et de groupes de la société civile a organisé des manifestations pacifiques contre le régime, qui ont souvent été réprimées avec violence. Les organisations de la société civile et les représentants de l'église chrétienne ont soutenu les revendications de l'opposition. Les élections législatives du 20 décembre 2018, boycottées par les principaux partis de l'opposition, ont permis une victoire facile du parti au pouvoir. Les élections locales, cruciales pour la démocratisation à la base, mais reportées à plusieurs reprises depuis 1987, ont été à nouveau reportées en décembre 2018 sine die. Le bilan du gouvernement en matière de droits de l'homme s'est amélioré mais reste médiocre. Malgré des améliorations indéniables du cadre et de l’apparence des principales institutions du régime au cours de la période considérée, la démocratie est loin d’être achevée. Cependant, la communauté internationale, notamment ses homologues africains du Togo, l’UA et la CEDEAO, a adopté une approche de «laisser-faire» dans l’intérêt de la stabilité régionale et de leurs intérêts nationaux face au Togo. La croissance économique est restée stable à environ 5% par an. Les investissements publics dans les infrastructures (par exemple, les routes et les ports) et l’augmentation de la productivité agricole, notamment des cultures d’exportation, ont été les principaux moteurs de la croissance économique. Cependant, la croissance reste vulnérable aux chocs extérieurs et au climat et n’a pas été inclusive. La croissance positive a été éclipsée par l'augmentation des inégalités interpersonnelles et régionales ainsi que par l'augmentation de l'extrême pauvreté. En outre, le blanchiment d’argent, les transferts d’argent illégal et le trafic se sont multipliés de manière alarmante. Le climat des affaires s’est néanmoins considérablement amélioré. ---------------------------------------------------------------------------------------------------------------------------------------------- ZUSAMMENFASSUNG: Der Gnassingbé-Clan hat das Land seit 1967 regiert. Die Forderungen nach institutionellen und Wahlrechtreformen sowie nach politischem Wandel bildeten während des Erhebungszeitraums das umstrittenste Thema zwischen der Regierung und den Herausforderern des Gnassingbé-Regimes. Ein Bündnis von Oppositionsparteien und zivilgesellschaftlichen Gruppen organisierte friedliche Demonstrationen gegen das Regime, die oft gewaltsam unterdrückt wurden. Zivilgesellschaftliche Organisationen und Vertreter der christlichen Kirche unterstützten die Forderungen der Opposition. Die Parlamentswahlen vom 20. Dezember 2018, die von den großen Oppositionsparteien boykottiert wurden, führten zu einem leichten Sieg der Regierungspartei. Die für die Demokratisierung an der Basis entscheidenden Kommunalwahlen, die seit 1987 immer wieder verschoben wurden, wurden im Dezember 2018 erneut auf unbestimmte Zeit verschoben. Die Menschenrechtsbilanz der Regierung hat sich verbessert, ist aber nach wie vor schlecht. Trotz unbestreitbarer Verbesserungen der Rahmenbedingungen und des Erscheinungsbildes der wichtigsten Institutionen des Regimes im Überprüfungszeitraum ist die Demokratisierung bei weitem nicht vollständig. Die internationale Gemeinschaft, insbesondere die afrikanischen peers des togosichen Präsidenten, die AU und die ECOWAS, verfolgten jedoch einen "Laissez-faire" -Ansatz im Interesse der regionalen Stabilität und ihrer nationalen Interessen im Umgang mit Togo. Das Wirtschaftswachstum blieb stabil bei etwa 5% pro Jahr. Öffentliche Investitionen in die Infrastruktur (z. B. Straßen, Häfen) und die Steigerung der landwirtschaftlichen Produktivität, insbesondere von Exportkulturen, waren die Hauptfaktoren des Wirtschaftswachstums. Das Wachstum bleibt jedoch anfällig für externe Schocks und das Wachstum war nicht inklusiv. Das positive Wachstum wurde durch die zunehmende Ungleichheit zwischen Personen und Regionen sowie durch die Zunahme extremer Armut überschattet. Darüber hinaus nahmen Geldwäsche, illegale Geldüberweisungen und Menschenhandel alarmierend zu. Das Geschäftsklima hat sich dennoch deutlich verbessert.

    Description: Fresh collections and their ascospore and conidial isolates backed up by type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-, complete ITS, partial LSU rDNA, rpb2, tef1 and tub2 sequences were used to evaluate the boundaries and species composition of Fenestella and related genera of the Cucurbitariaceae. Eight species, of which five are new, are recognised in Fenestella s.str., 13 in Parafenestella with eight new species and two in the new genus Synfenestella with one new species. Cucurbitaria crataegi is combined in Fenestella, C. sorbi in Synfenestella, Fenestella faberi and Thyridium salicis in Parafenestella. Cucurbitaria subcaespitosa is distinct from C. sorbi and combined in Neocucurbitaria. Fenestella minor is a synonym of Valsa tetratrupha, which is combined in Parafenestella. Cucurbitaria marchica is synonymous with Parafenestella salicis, Fenestella bavarica with S. sorbi, F. macrospora with F. media, and P. mackenziei is synonymous with P. faberi, and the latter is lectotypified. Cucurbitaria sorbi, C. subcaespitosa and Fenestella macrospora are lecto- and epitypified, Cucurbitaria crataegi, Fenestella media, F. minor and Valsa tetratrupha are epitypified in order to stabilise the names in their phylogenetic positions. A neotype is proposed for Thyridium salicis. A determinative key to species is given. Asexual morphs of fenestelloid fungi are phoma-like and do not differ from those of other representatives of the Cucurbitariaceae. The phylogenetic structure of the fenestelloid clades is complex and can only be resolved at the species level by protein-coding genes, such as rpb2, tef1 and tub2. All fungal species studied here occur, as far as has been possible to determine, on members of Diaporthales, most frequently on asexual and sexual morphs of Cytospora.

    Description: Members of the genus Cytospora are often reported as endophytes, saprobes or phytopathogens, primarily causing canker diseases of woody host plants. They occur on a wide range of hosts and have a worldwide distribution. Although several species have in the past been reported from China, the vast majority are not known from culture or DNA phylogeny. The primary aim of the present study was thus to clarify the taxonomy and phylogeny of a large collection of Cytospora species associated with diverse hosts in China. Cytospora spp. were collected in northeast, northwest, north and southwest China, indicating that the cold and dry environments favour these fungi. In this paper, we provide an assessment of 52 Cytospora spp. in China, focussing on 40 species represented by 88 isolates from 28 host genera. Based on a combination of morphology and a six-locus phylogeny (ITS, LSU, act1, rpb2, tef1-α and tub2), 13 new species and one new combination are introduced. The majority of the species investigated here appear to be host-specific, although further collections and pathogenicity studies will be required to confirm this conclusion.

    Description: The Caloveto area in North-East Calabria hosts a stratigraphic succession which documents the evolution from shallow water carbonates to deeper-water pelagic and hemipelagic deposits, bearing ample evidence for severe tectonic control on Jurassic and Lower Cretaceous sedimentation. Geological mapping indicates that the shallow-water carbonates, also with coral assemblages, formed a narrow fringe around a high of the Hercynian basement, made of lowgrade metamorphic rock, which remained emergent throughout the Pliensbachian and became an intrabasinal high which stood proud of the Longobucco basin, hosting thin pelagic sedimentation through most of the Jurassic. An extensional phase in the Toarcian disrupted and foundered the benthic carbonate factory, whose drowning is documented by a change to Rosso Ammonitico-type deposits. This resulted in a complex network of neptunian dykes (also intruding the basement) and in-situ breccias. Starting in the late Toarcian, the rugged submarine topography was gradually leveled by onlapping marls, radiolarites and pelagic limestone, which sealed the Toarcian fault zones producing a diverse array of unconformities. Colonization by microbial communities characterizes the initial stages of marine sedimentation around the cores of Paleozoic basement, as banded polychrome microbialites and ?swollen? phyllites, a result of the microbially-influenced/induced displacive growth of calcium carbonate crystals along split cleavage planes, constitute an unexpected field tool for identifying basin margins. Silicified marginal zones in the shallow water limestone characterize, in analogy with other Tethyan regions, the onlap unconformities of chert-rich basinal units on the submerged carbonate fringes.

    Description: Lampedusa Island represents a key-area due to its central position within the Sicily Channel and the whole Mediterranean region. The acquisition and interpretation of sixteen 'sparker-system' seismic lines allowed a refined reconstruction of the sedimentary architecture of the Lampedusa continental shelf and the detailed timing of its tectonic evolution, providing a contribution to the geodynamic processes affecting this sector of the Sicily Channel. The offshore profiles show five seismic facies, which have been compared with the onshore succession. The older seismic unit (S1) was correlated with the pre-rift Cala Pisana Mb. of the Lampedusa Fm., separated by the overlain Capo Grecale Mb. (=S2) by an erosional surface, identified with the offshore TU (=Tortonian Unconformiy) horizon, passing upward to the Vallone della Forbice Mb. (=S3) through a gradual, concordant boundary (Upper Tortonian Boundary=UTB). Capo Grecale and Vallone della Forbice Mbs., and thus the S2 and S3 units, represent the syn-rift deposits, recording the Late Miocene extensional tectonic activity. The effects of the strong erosional phase connected with the Mediterranean Salinity Crisis of Messinian age, are visible in all the seismic lines coinciding with a high impedance irregular surface (MH=Messinian Horizon), above which a further seismic unit (S4) develops. This latter, constituted by reflections onlapping the substratum, in the lower part, and prograding in the upper one, does not find an onshore correspondence, but has been attributed to the post-Messinian (Zanclean) transgression, followed by the subsequent regressive phase (Piacenzian-Gelasian). The uppermost seismic unit (S5), unconformably covering the older substratum, through the Early Pleistocene Unconformity (=EPU horizon) corresponds to the Pleistocene-Holocene onshore deposits. The seabed (top of S5) shows regular morphologies in the southern sector, while in the northern sector it is cut by erosive channels connected to strong streams on the bottom. From a structural point of view, the southern sector recorded an extensional tectonic phase, giving rise to normal faults involving units from S1 to S3, sutured by the MH and the overlain deposits. In the northern sector, the tectonic phase continued until the Pliocene, also involving the S4 unit. The reconstructed tectonic setting well fits the more general setting of the Sicily Channel Rift Zone, where main WNW-ESE faults were active during the Late Miocene and until the Pliocene age, generating small depositional areas, bounded by second-order NNWSSE normal faults.

    Description: Many buildings of the historic centre of Urbino (Marche, Central Italy), included in the UNESCO World Heritage List, are characterized by portals consisting of sedimentary rocks such as limestones or sandstones. In order to identify the possible quarries of provenance of sandstones used for architecture, we addressed our research to the Sant'Ippolito area (20 km ESE of Urbino), where historical stonemasons have been extensively documented since the 14th century. Few traces of ancient exploitation indicate some extraction sites. All the investigated rocks (both from monumental portals of Urbino and geological outcrops) consist of fine to medium grainsize sandstones with a variable content of bioclasts. Two different groups were recognized (using the petrographic Q-F-R classification diagram): (i) lithic arenites belonging to the Colombacci Formation; and (ii) feldspathic lithic arenites referable to the Tripoli Unit. In particular, petrographic data indicate that the sandstones used in the historical buildings of Urbino, come from the arenitic lithofacies of the Messinian p.p. Colombacci Formation of the Sant'Ippolito area. In addition, comparative geochemical studies of whole rock major and trace elements point out three outcrops, of the above formation, as possible sites of ancient extraction. Sandstones of the Tripoli Unit and the Marnoso-Arenacea Formation, widespread in the study area and near Urbino respectively, are ruled out as source rocks, based on both petrographic and geochemical data. Anomalously high values of some heavy elements such as Pb, Zn and As, recognized in some of the portals, likely derive from a combination of various anthropogenic sources of pollution close to the investigated monuments, such as domestic heating and emissions from road traffic in the past. From a mechanical point of view, the uniaxial compressive strength tests, carried out on a representative number of selected samples of the Colombacci Formation lithic arenites, yelded low values and high variability. Other investigated physical parameters also indicate that the stones used for the portals did not represent a good choice as building material. This implies that the stonemasons of Sant'Ippolito chose local raw materials for their availability, aesthetic qualities and good workability, rather than structural properties.

    Description: The Elazig and Tunceli provinces in eastern Anatolia host a complex succession of Miocene-Pleistocene effusive and explosive volcanic rocks, divided into four distinct volcanic phases. The most abundant and widespread products are the calcalkaline Mazgirt volcanic rocks, characterized by wide Sr isotope variations (87Sr/86Sr ~0.7054-0.7077) and narrower 143Nd/Nd (~0.51246-0.51260) and Pb isotopes (e.g., 206Pb/204Pb ~18.89-19.13). New 40Ar-39Ar ages indicate that Mazgirt volcanic activity occurred between ~16.3 and 15.1 Ma. The other three volcanic phases are represented by the Tunceli mildly alkaline basaltic lavas (~11.4-11.0 Ma), and the Pliocene Karakoçan (~4.1 Ma) and Pleistocene Elazığ (~1.9-1.6 Ma) Na-alkali basaltic lavas with clear OIB-like geochemical signature. Mazgirt volcanics can be subdivided on the base of mode of emplacement into lava flows and lava domes units characterized by petrographic, chemical and isotopic and differences: lava flows are calcalkaline, whereas lava domes mostly belong to a high-K calcalkaline series and are, on average, more LREE- and 87Sr-enriched. Lava domes are more porphyritic, with a phenocryst assemblage dominated by amphibole, whereas plagioclase and clinopyroxene are the most abundant phenocryst phases in lava flows, pointing out that evolution of dome magmas occurred in conditions of slightly higher pressure, favouring the crystallization of hydrous phases. The Karabakır Formation, previously reported as late Miocene-Pliocene, encloses Mazgirt volcanics and is capped by Tunceli basalts. These new age data constrain the Karabakır Formation emplacement from early to late Miocene. The evolution of this igneous activity mirrors the geodynamic framework of the region: the early-middle Miocene Mazgirt volcanics represent arc volcanism related to Eurasia-Arabia convergence. The late Miocene Tunceli basalts postdate the onset of post-collisional tectonics in Eastern Anatolia, whereas the Karakoçan and Elazığ volcanic rocks were emplaced after the initiation of strike-slip motion on the North Anatolian and East Anatolian Fault systems.

    Description: Mass-transport deposits (MTDs) intercalated in slope/basinal successions, produced by submarine collapses and mass flows, are generally constituted of allochthonous elements sourced from platform margins. Here we present a noticeable exception where Toarcian calciclastic deposits made of pelagic carbonate elements are embedded in other pelagic carbonates. Selected outcrops pertaining to the Rosso Ammonitico Fm of three different pelagic carbonate platform (PCP)-basin systems were studied. The pelagic successions of the study areas onlap Early Jurassic structural highs. These clastic bodies partially replace the typical Toarcian reddish marls and shales of the Umbria-Marche-Sabina palaeogeographic Domain at different stratigraphic levels. The clasts range from blocks to megablocks; extraclasts of Corniola facies (Pliensbachian) and, sporadically, of Calcare Massiccio peritidal carbonates (Hettangian) are associated with Rosso Ammonitico intraclasts. The internal architecture of the MTDs and their emplacement processes, as well as their source and accumulation areas, were identified. Three distinct lithofacies characterise the clastic bodies, each one corresponding to a different emplacement process or to a different portion of the flow. The occurrence of lithified megablocks (〉20 m across) of Corniola Fm suggests the exhumation of the buried portion of the unit. Synsedimentary extensional tectonics is the most likely triggering mechanism. Sedimentological analysis, coupled with geological mapping of the study areas, reveals the key role played by PCPs in the genesis of these MTDs. The early Toarcian reactivation of Hettangian palaeofaults bounding the structural highs is inferred. These faults, characterised by moderate offsets, crosscut the onlap wedges of the hangingwall successions, exhuming the older and lithified portion of Corniola Fm. Once became inactive, the fault planes were then eroded producing palaeoescarpments. Their backstepping, coupled with seismic shocks, produced the accumulation of the study clastic bodies.
