Abstract Francoprovençal has generally been viewed as an oral dialect group with a highly varied character (due to the mountainous regions of the Alps, the Jura and the Massif Central), and with no elaborated written textual tradition. The virtual absence of such a tradition may indeed be observed for the modern period (i.e. the second half of the second millennium). However, this is not the case for the medieval period, during which Francoprovençal underwent a process of elaboration similar to that of the neighbouring Romance languages, at first fragmentary and embedded in Latin. From these beginnings emerged a pure Romance scripta which remained in existence until the end of the 15th century, when it was replaced by French. This process remained incomplete, characterised by the continuous copresence of either Latin or French and essentially limited to legal and administrative documents. Nonetheless, the first half of the second millennium yields a complex written vernacular which displays both diatopic and diachronic variation, and which has never before undergone systematic analysis. The present contribution is based on a corpus of medieval documents from the Francoprovençal regions of France and Switzerland (approx. 700.000 words), digitised as part of the project Documents linguistiques galloromans and presented for the first time here. Taking one of the most salient and frequent phenomena as an example – the outcome of lat. /a/ in tonic free syllables (ˈpratu> Frpr. pra vs Fr. pré) – the authors assess the nature and extent of the presence of Francoprovençal in medieval scripturality, examining a total of 60.000 occurrences. The results thus obtained allow an interpretation of the historical development of Francoprovençal on the basis of entirely new evidence.

Cribellopsis Arnaud-Vanneau (upper Berriasian-Albian) represents a rather simple structured orbitolinid species that are classically differentiated above all by dimensional and morphological criteria. Previously reported from the upper Hauterivian to Albian interval, a new species is described as Cribellopsis delicatula n. sp. from the upper Berriasian-lower Valanginian of France, Switzerland ("Jura Mountains"; Vions, Chambotte, and Vuache formations), and Iran (Fahliyan Formation). Known since the sixties from southwestern Europe, it has been figured several times since then in open nomenclature. C. delicatula n. sp. is characterized by its high-conical test and delicate structural elements, combined with a reduced chamber height. Most Valanginian occurrences of the Orbitolinidae (including Cribellopsis) are from the former northern Neotethyan margin (Spain, France, Sardinia/Italy, Switzerland, Romania, Bulgaria, Serbia). Cribellopsis delicatula n. sp. represents the oldest known species of the genus and is here reported from both margins of the former Neotethyan ocean.

Abstract This study focuses on a geological section in the Jura Mountains across the villages of Travers, La Brévine in Switzerland, and Morteau in France. Field mapping was conducted to complement and densify existing data. A kinematically and geometrically consistent forward model has been developed to understand and interpret the observed surface structures. The proposed solution features a low-angle thrust fault with a multiple ramp-flat or staircase trajectory on which several hinterland-verging thrusts nucleate. The main décollement level is located in the Triassic evaporites of the Keuper and Muschelkalk Groups. Our model implies secondary detachments in the Opalinus Clay and the Cretaceous layers leading to repetitions in the Mesozoic cover rocks over large distances. This in turn explains the high topographic position of exposed sediments. The proposed solution is an alternative to models showing overthickening of Triassic evaporites associated with a single detachment level. Along the investigated profile, the Jura Mountains accommodate a shortening of 8.5 km. The kinematic forward model suggests an oscillating sequence of thrusting, rather than a simple, in sequence, forward propagation succession of thrusts.

SUMMARY The Greater Geneva Basin (GGB), located in southwestern Switzerland and neighboring France, is enclosed by the rotating northwestern edge of the Alpine front and the Jura mountains chain. Recently, this basin has received increasing attention as a target for geothermal exploration. Historical and instrumental seismicity suggest that faults affecting the basin may still be active. Moderate-magnitude earthquakes have been located along the Vuache fault, a major strike-slip structure crossing the basin. Before geothermal exploration starts, it is key to evaluate the seismic rate in the region and identify possible seismogenic areas. In this context, we deployed a temporary seismic network of 20 broad-band stations (from September 2016 to January 2018) to investigate the ongoing seismic activity, its relationship with local tectonic structures, and the large-scale kinematics of the area. Our network lowered the magnitude of completeness of the permanent Swiss and French networks from 2.0 to a theoretical value of 0.5. Using a new coherence-based detector (LASSIE - particularly effective to detect microseismicity in noisy environments), we recorded scarce seismicity in the basin with local magnitudes ranging from 0.7 to 2.1 ML. No earthquakes were found in the Canton of Geneva where geothermal activities will take place. We constructed a local ’minimum 1-D P-wave velocity model’ adapted to the GGB using earthquakes from surrounding regions. We relocated the events of our catalogue obtaining deeper hypocentres compared to the locations obtained using the available regional velocity models. We also retrieved eight new focal mechanisms using a combination of polarities and waveform inversion techniques (CSPS). The stress inversion shows a pure strike-slip stress regime, which is in agreement with structural and geological data. Combining the background seismicity with our catalogue, we identified seismogenic areas offsetting the basin.

Abstract K/Ar ages and oxygen isotope compositions were determined on illitic clay fractions of Purbeckian marls from the Swiss and French Jura Mountains in order to examine their syn-depositional origin which had previously been suggested based on sedimentological and mineralogical data. Measured ages range between 122.3+ or -2.3 Ma and 136.5+ or -2.5 Ma, thus being either coeval or slightly younger than the accepted age of sedimentation (Jurassic/Cretaceous boundary). Because total burial depth was less than 1000 m, delta 18 O values around 20 per mil are compatible with a formation of illite by replacement of smectite in an evaporated sea-water. Therefore, in addition to the two common types of illite resulting either from the fragmentation of pre-existing micas or diagenetic formation in deeply-buried sediments, illitic clay minerals formed at low temperature do exist and may be useful for age determination.

Lagoonal to intertidal sediments from the Holocene in Florida Bay,on the Bahamas, and in Bermuda are compared to similar facies in theKimmeridgian and Berriasian of the Swiss and French Jura Mountains.Dating by 14C permits the estimation of sediment accumulationrates in the Holocene. In the ancient outcrops, the timing is givenby cyclostratigraphic analysis. Elementary depositional sequencesformed in tune with the 20-ka precession cycle, although much ofthis time may have been spent in non-deposition and/or erosion. Afterdecompaction of the ancient sequences, their accumulation rates canbe evaluated. It is suggested that the studied Holocene sedimentsaccumulated over the past 6000 years with rates of 0.3 to 3 mm/a,whereas the Kimmeridgian and Berriasian facies show somewhatlower rates of 0.07 to 0.6 mm/a. This difference may be due to methodological errors, but also to variable carbonate production. In shallow carbonate systems, much of the sediment produced may be redistributed over the platform or exported. Furthermore, basin morphology and currents can strongly influence facies and thickness of the accumulated sediment. Finally, the accumulated sediment may suffer further erosion before it is preserved in the sedimentary record. Consequently, when estimating sedimentation rates in ancient sequences, it is important to do this with the highest time resolution possible, and only after having decompacted the sediment and evaluated the time lost in hiatuses or condensed intervals.

Abstract. We present a dataset of grape harvest dates (GHD) series that has been compiled from international and non-translated French and Spanish literature and from unpublished documentary sources from public organizations and from wine-growers. As of June 2011, this GHD dataset comprises 378 series mainly from France (93% of the data) as well as series from Switzerland, Italy, Spain and Luxembourg. The series have variable length and contain gaps of variable sizes. The longest and most complete ones are from Burgundy, Switzerland, Southern Rhône valley, Jura and Ile-de-France. The GHD series were grouped into 27 regions according to their location, to geomorphological and geological criteria, and to past and present grape varieties. The GHD regional composite series (GHD-RCS) were calculated and compared pairwise to assess the quality of the series. Significant (p-value < 0.001) and strong correlations exist between most of them. As expected, the correlations tended to be higher when the vineyards are closer, the highest correlation (R = 0.91) being obtained between the High Loire Valley and the Ile-de-France GHD-RCS. The strong dependence of vine cycle on temperature and, therefore, the strong link between GHD and the temperature of the growing season was also used to test the quality of the GHD series. The strongest correlations are obtained between the GHD-RCS and the temperature series of the nearest weather stations. Moreover, the GHD-RCS/temperature correlation maps show spatial patterns similar to temperature correlation maps. The stability of the correlations over time is explored. The most striking feature is their generalized deterioration at the late 19th–early 20th turning point. The possible effects on the GHD of the phylloxera crisis, which took place at this time, are discussed. The median of the standardized GHD-RCS was calculated. The distribution of the extreme years of this general synthetic series is not homogenous. Extremely late years all occur during a two-century long time-window from the early 17th to the early 19th century, while extremely early years are frequent during the 16th and since the mid-19th century. The dataset is made accessible for climate research through the Internet. It should allow a variety of climate studies, including reconstructions of atmospheric circulation over Western Europe.

The diet of the Barn Owl ( Tyto alba (Scopoli, 1769)) was studied over an 8-year period in the Jura mountains of France, during two population surges of its main rodent prey (common voles, Microtus arvalis (Pallas, 1778), and European water voles, Arvicola terrestris (L.,1758)), allowing us to test whether T. alba is an opportunistic predator as is often cited in the literature or exhibits more complex patterns of prey selection as is reported in arid environments. Small mammals were sampled by trapping and index methods. We observed (i) significant correlations between the proportions of A. terrestris, M. arvalis, and woodland rodents in the diet and their respective densities in the field; (ii) interactions between populations of A. terrestris and M. arvalis, indicating that the proportion of each species in diet was affected by the density of the other; (iii) proportions of red-toothed shrews (genus Sorex (L., 1758)) in the diet did not correlate with their abundance in the field, indicating that those species were likely to be preyed upon when others were no longer available. This confirms that T. alba is generally opportunistic; however, prey selection of a focal species (e.g., Sorex spp., grassland species) can be affected by the density or availability of the other prey species.

We present an open-access dataset of grape harvest dates (GHD) series that has been compiled from international, French and Spanish literature and from unpublished documentary sources from public organizations and from wine-growers. As of June 2011, this GHD dataset comprises 380 series mainly from France (93% of the data) as well as series from Switzerland, Italy, Spain and Luxemburg. The series have variable length (from 1 to 479 data, mean length of 45 data) and contain gaps of variable sizes (mean ratio of observations/series length of 0.74). The longest and most complete ones are from Burgundy, Switzerland, Southern Rhône valley, Jura and Ile-de-France. The most ancient harvest date of the dataset is in 1354 in Burgundy. The GHD series were grouped into 27 regions according to their location, to geomorphological and geological criteria, and to past and present grape varieties. The GHD regional composite series (GHD-RCS) were calculated and compared pairwise to assess their reliability assuming that series close to one another are highly correlated. Most of the pairwise correlations are significant (p-value < 0.001) and strong (mean pairwise correlation coefficient of 0.58). As expected, the correlations tend to be higher when the vineyards are closer. The highest correlation (R = 0.91) is obtained between the High Loire Valley and the Ile-de-France GHD-RCS. The strong dependence of the vine cycle on temperature and, therefore, the strong link between the harvest dates and the temperature of the growing season was also used to test the quality of the GHD series.

ABSTRACT The year 2019 marks the 80th anniversary of the start of the Second World War and the 75th anniversary of the Allied landings in Normandy: respectively the first major conflict in which geologists were deployed professionally in uniform by opposing sides from the start of hostilities, and the first successful major amphibious assault whose planning was significantly influenced by geologists. ‘Military geology’ had become established within major world powers as a discipline relevant to military operations, following its initial development in the First World War. The term in English had entered scientific literature via publications in the USA from 1917 onwards, initially by Joseph Ezekiel Pogue, Jr (1887–1971). This followed use of ‘Militärgeologie’ from 1913 by Walter Kranz (1873–1953) in Germany, a term subsequently used also in Austria-Hungary, although mostly replaced by ‘Kriegsgeologie’ in both nations from 1915 and by ‘Wehrgeologie’ from about 1935. However, ‘géologie militaire’ was in French use even earlier, notably in the sub-titles of books by an infantry officer, Joseph-Charles-Auguste Clerc (1840–1910), on the French Alps in 1882 and the Jura mountains in 1888. This term complemented use of ‘géographie militaire’, a name in use since 1836 for a subject whose study was given impetus in France by defeat in the Franco-Prussian War of 1870–1871. In recent years ‘military geoscience’ has come into more popular use, reuniting military geology with geography and embracing associated disciplines.

25 years ago, my friend Guido Volpe (Castel Volturno, Campania) asked me for help to identify the Grayling species occurring in his region. In summer 1998, I started several rearing experiments with batches of ova from Italy to check their identity with the help of the larval stages. Guido Volpe procured the females for oviposition on different sites in the mountains of Lazio, Campania and Calabria and sent the obtained ova by mail to Switzerland. The question arose soon, which one of the two smaller Grayling species was indigenous to this region, Hipparchia genava or alcyone. In his study “Contribution à l’étude des Satyrinae de France”, Patrice Leraut (1990) elevated to species rank the taxon genava Fruhstorfer (1908) occurring in the Valais, claiming that its distribution area extends across the whole Italy to eastern Sicily. I hoped to confirm this assertion, being based mainly on the rods of the Jullien organ, also in the larval stages. For this purpose, I was forced to examine rearing series from the entire area inhabited by populations of the two smaller Grayling species. During the period 1998 to 2006, I investigated them with series from 8 European countries in total (see Jutzeler et al. 2005, map p. 152), by rearing them always from the ovum. In fact, the two smaller species alcyone and genava produced caterpillars of different appearance. The imagines that emerged under rearing conditions were retained to search them for characters being typical of each of the two species. The results from all these rearing experiments were recorded in the study on H. fagi and genava (Volpe and Jutzeler, 2001 – genava still named there alcyone) and in 3 studies being dedicated to alcyone and genava (Jutzeler et al., 2002, 2005, 2006). Already in those days, I didn’t use the name of “hermione Linnaeus, 1764” favoured by Kudrna (1977) to rename H. alcyone D. & S. In my eyes, it referred to two different species. Moreover, Kudrna’s lectotype designation did not conform to the rules of ICZN according to Higgins and Riley (1978) and I had detected during my investigations that this name was applied to designate the taxon fagi since 1775 until the mid-20th century and that it was often used in reality to designate unknowingly also the similar species genava. The synonymy of Papilio hermione Linnaeus, 1764 with P. fagi Scopoli, 1763 has been irrevocably established recently by Russell and Vane-Wright (2022). In the first part of “Doubts about the validity”, I posited the recognition of the specific rank of Hipparchia genava. Since the beginning of my research program on the Grayling complex, I tackled this question under various aspects. Of central importance was the determination of the characteristics of wings using reared imagines of the three Grayling species resulting from the numerous rearing series of Hipparchia alcyone, genava and fagi. The most important variations found among caterpillars and imagines are presented once again in this part of the study. Furthermore, the evaluation of preparations housed in the collections of the Zoological Museum Amsterdam (since 2011 housed in the Naturalis Biodiversity Centre Leiden) and other museums being figured on the 9 synoptical plates together with their genital armatures, was of primary importance for the present article. Thereby, the accuracy of Leraut’s (1990) diagnosis could be confirmed in the main, but with the limitation that the number of rods of the Jullien organ of alcyone and genava can also be beyond the range indicated by Leraut. Thus, the rods do not compellingly lead to a correct identification of every individual. As a new character of male genitalia, the strongly curved inferior edge of the male genital armature of H. alcyone should be noted. Accompanied by Peter Russell, I verified also Fruhstorfer’s (1908a) type material of H. genava housed at the British Museum of Natural History in London (BMNH). Contrary to all of the ever-voiced findings by Kudrna, all the individuals of the type series in London accorded perfectly with genava from the Valais using the wing characteristics. The variability of the wing design of H. genava (and fagi) is additionally illustrated with the figures reproduced from plate 73 of Verity’s 5th volume “Satyridae” (1953) of his work “Farfalle Diurne d’Italia”. The occurrence of Grayling species in some selected actual and historical distributional areas was furthermore checked by using material in collections. Accordingly, the Palatinate region was populated only by alcyone. Proofs that genava existed in this region do not seem to exist. Of the two small Grayling species in Alsace, Hipparchia genava still occurs in the Alsatian Jura (Haut-Rhin) whereas H. alcyone formerly populated, until the 1960s, some sites in the northern part of the Vosges (Bas-Rhin). In the Jura Mountains of Basel and Solothurn, only H. genava occurs, whereas alcyone and fagi are completely absent from those areas. In Liguria, H. fagi and genava are widespread whereas only 4 specimens representing alcyone could be detected from this region being collected in 1973 near Celle Ligure (Savona). I supported the inquiries in the field by Tristan Lafranchis and colleagues in the region of the contact areas of H. genava and alcyone in south-eastern France. Accordingly, Duponchel (1832-35) diagnosed correctly the occurrence of H. alcyone in the surroundings of Marseille. Individuals of H. alcyone from this region were described by Fruhstorfer as ssp. sogdiana, whereas Varin (1962) referred ssp. sogdiana erroneously to the “altitudinal form” corresponding with H. genava, considering the true alcyone from mount Faron near Toulon (Var) as “under-race faronica” of ssp. sogdiana (sensu genava).

AbstractThe Hauterivian–Barremian series of the Jura Mountains were measured over more than 60 sections along a 200 km long transect between Aix-les-Bains (Savoie Department, France) and Bienne (Bern Canton, Switzerland), which prompted the need for a revision and improvement of the current lithostratigraphic scheme for this stratigraphic interval. A new formation, the Rocher des Hirondelles Formation, is proposed in replacement of the unsuitable Vallorbe Formation, while the Gorges de l'Orbe Formation is formally described. The Gorges de l'Orbe Formation, equivalent to the well-known “Urgonien jaune” facies, consists of two members, namely Montcherand Member and Bôle Member. The Rocher des Hirondelles Formation, equivalent to the “Urgonien blanc” facies, consists of three members, i.e. Fort de l'Écluse Member, Rivière Member and Vallorbe Member. The marly Rivière and Bôle members appear to present time-equivalent lithostratigraphic units, recording a major sedimentological event affecting contemporarily both formations. This study proposes a new sedimentary model opening a new point of view on the long-living controversies about the age of the Urgonian series from the Jura Mountains. The data point to strong diachronic ages of lithostratigraphic units with a late Hauterivian to early Barremian occurrence of the “Urgonian blanc” facies in the Meridional Jura area versus a latest Barremian age in the Central Jura area, reflecting a general progradation of the Urgonian shallow-water carbonate platform from the present-day Meridional Jura area toward external deeper-water shelf environments of the present-day Central Jura area and Molasse basin.

AbstractThe north‐western Alpine foreland in Switzerland and France comprises the Late Miocene Jura Mountains, considered a type example for thin‐skinned thrusting where deformation of the sedimentary cover is decoupled from the basement along a regional basal detachment. To what extent basement faults were involved during its deformation is a matter of debate. We use 3D seismic data to investigate the deformation style along the easternmost tip of the Jura range in unprecedented detail. Here, basement‐rooted normal faults were not only repeatedly reactivated before thrust belt formation but also contemporaneously active as reverse/transpressional faults. They either propagated up into the Mesozoic succession without interruption (‘hard linkage’) or apparently controlled the localisation of Mesozoic faults via smaller‐scale shear zones (‘soft linkage’). Our analysis of the resulting fault geometries questions the existence of a large‐scale basal detachment in this area and points out the importance of thick‐skinned fault reactivation.

The Eurasian lynx reappeared in the French Jura Mountains, in the late 1970s, as the result of the dispersion of lynxes from the Carpathian region reintroduced in Switzerland in the early 1970s. Since then, the state of this population has remained poorly known. One estimate gives the number of individuals between 120 and 150. Opportunistic observation and monitoring suggest poor connectivity with the populations in Germany or in other parts of Switzerland. Forty years after its comeback in France, we could expect a higher number of individuals, but possible inbreeding depression as well as threats such as poaching and collisions with cars may explain the limitation of number of individuals observed and may lead to a new extinction of the specie in this region. We used 23 microsatellite markers and 78 DNA samples, collected between 2008 and 2020, to establish the genetic state of the French Jura Mountain lynx population. Our results show extremely low genetic diversity with an observed heterozygosity (Ho) of 0.36 and an effective population size (Ne) of 38.2. When comparing the source population (Carpathian), the inbreeding level is very worrying (Fe = 0.41). These results are among the lowest recorded for the Eurasian lynx. To avoid extinction, which we estimate will occur in approximately 30 years, we recommend the introduction of new genetic material. Although reintroduction is controversial, solutions such as the replacement of poached lynxes and the exchange of orphan lynxes between care centers are good initial actions for population strengthening. This offers a rapid intervention while studying solutions for more sustainable conservation
