Abstract:

La faune des vertébrés inférieurs (poissons) des Grès de Gaspé était presque inconnue il y a 50 ans, sauf un Cephalaspis ostéostracé (poisson sans mâchoires) décrit en 1954 par Russell, dont Belles-Isles a changé le genre en 2011. En 1969, Pageau a décrit d’autres Ostéostracés : des Placodermes Arthrodires (poissons avec mâchoires), des Acanthodiens (poissons avec épines osseuses aux nageoires) et des Sélaciens (requins). Dans cet article, 2 spécimens rares d’Arthrodires sont décrits dans leur contexte géologique, un milieu deltaïque fait de dépôts provenant de l’érosion d’une chaîne de montag

Abstract Le gisement Autunien de Muse est célèbre pour ses richesses paléontologiques et notamment pour sa « couche aux poissons » dans laquelle les Aeduellidae (Pisces, Actinopterygii) sont particulièrement abondants. Alors que l’histoire de ce gisement est bien documentée à partir de la fin des années 1830, les premières recherches paléontologiques et géologiques qui y ont été faites avant cette période, restent encore mal connues. Un manuscrit inédit d’Alexander von Humboldt révèle qu’il avait étudié en mars 1805 la géologie de la région d’Autun où il avait reconnu le Zechstein. Un témoigna

Abstract:

Over the past 170 years, the Late Devonian Miguasha biota from eastern Canada has yielded a diverse aquatic assemblage including 20 species of lower vertebrates (anaspids, osteostracans, placoderms, acanthodians, actinopterygians and sarcopterygians), a more limited invertebrate assemblage, and a continental component including plants, scorpions and millipedes. Originally interpreted as a freshwater lacustrine environment, recent paleontological, taphonomic, sedimentological and geochemical evidence corroborates a brackish estuarine setting. Over 18,000 fish specimens have been recovered showi

Abstract:

The stratigraphic distribution of fossil species contains potential information about phylogeny because some phylogenetic trees are more consistent with the distribution of fossils in the rock record than others. A maximum likelihood estimator of phylogeny is derived using an explicit mathematical model of fossil preservation. The method assumes that fossil preservations within lineages follow an independent Poisson process, but can be extended to include other preservation models. The performance of the method was examined using Monte Carlo simulation. The performance of the maximum likelihoo

Abstract:

The fossil record is a rich source of information about biological diversity in the past. However, the fossil record is not only incomplete but has also inherent biases due to geological, physical, chemical and biological factors. Our knowledge of past life is also biased because of differences in academic and amateur interests and sampling efforts. As a result, not all individuals or species that lived in the past are equally likely to be discovered at any point in time or space. To reconstruct temporal dynamics of diversity using the fossil record, biased sampling must be explicitly taken in

Abstract:

The fossil record is incomplete in the sense that taxa for which there are no preserved finds are unrepresented. Because the probability that there is at least one preserved find is greater for long-lived taxa, failure to account for this effect will bias estimation of mean taxonomic duration. This paper describes maximum likelihood estimation of mean taxonomic duration, fossil preservation rate, and completeness of the local fossil record under a model in which duration has an exponential distribution and the locations of preserved finds follow a Poisson process.

Abstract:

Rate distributions are important considerations when testing hypotheses about morphological evolution or phylogeny. They also have implications about general processes underlying character evolution. Molecular systematists often assume that rates are Poisson processes with gamma distributions. However, morphological change is the product of multiple probabilistic processes and should theoretically be affected by hierarchical integration of characters. Both factors predict lognormal rate distributions. Here, a simple inverse modelling approach assesses the best single-rate, gamma and lognormal

The mechanical properties of any substance are essential facts to understand its behaviour and make the maximum use of the particular substance. Rocks are indeed an important substance, as they are of significant use in the energy industry, specifically for fossil fuels and geothermal energy. Attenuation of seismic waves is a non-destructive technique to investigate mechanical properties of reservoir rocks under different conditions. The attenuation characteristics of five different rock types, siltstone, shale, Australian sandstone, Indian sandstone and granite, were investigated in the labor

Abstract Fossil fuel producers have a major role to play in curbing greenhouse gas emissions through supply-side initiatives. Yet, no study has systematically assessed the determinants of efforts to constrain fossil fuel production for climate purposes. This article develops a conceptual framework for factors potentially affecting country-level initiatives to keep fossil fuels in the ground. Using data for 124 countries with fossil fuel reserves for 2006–2019 and multivariate Poisson regression analysis, we identify factors influencing the use of such constraints by national governments.

Abstract Background Indoor air pollution (IAP) remains a major global public health hazard more so in developing countries where use of fossil fuels is still very common. However, despite the popularity of kerosene and fuelwood as energy sources among many households in the Sub-Saharan Africa, little is known about their health effects and the predisposing factors particularly on those with direct exposure. This study sought to relate indoor air pollution exposure to self-reported prevalence of respiratory outcomes including (sputum production, congestion, breathing difficulties, eye problems,
