  • Recent magmatism drives hydrocarbon generation in north-east Java, Indonesia. [Journal Article]
    Sci Rep 2020; 10(1):1786Zaputlyaeva A, Mazzini A, … Frieling J
  • Conventional studies of petroleum basins associate oil generation with the gradual burial of organic-rich sediments. These classical models rely on the interplay between pressure, temperature, and the time required for organic matter transformation to oil and gas. These processes usually occur over geological timescales, but may be accelerated by rapid reactions when carbon-rich sediments are exp…
  • Cytogenetic and pollen identification of genus Gagnepainia (Zingiberaceae) in Thailand. [Journal Article]
    Comp Cytogenet 2020; 14(1):11-25Moonkaew P, Nopporncharoenkul N, … Umpunjun P
  • Gagnepainia godefroyi K. Schumann, 1904 and G. harmandii K. Schumann, 1904 belong to the genus Gagnepainia K. Schumann, 1904 of the Ginger family. They have the potential to be developed as medicinal and attractive ornamental plants. To date, the knowledge on the cytological and reproductive aspects of Gagnepainia have not been publicly available. Therefore, the aims of this research are to inves…
  • Application of Autofluorescence for Confocal Microscopy to Aid in Archaeoparasitological Analyses. [Journal Article]
    Korean J Parasitol 2019; 57(6):581-585Morrow JJ, Elowsky C
  • Confocal laser scanning microscopy (CLSM) was used to examine archaeoparasitological specimens from coprolites associated with La Cueva de los Muertos Chiquitos (CMC) located near present-day Durango, Mexico. The eggs for 4 different types of parasites recovered from CMC coprolites were imaged using CLSM to assist with identification efforts. While some of the parasite eggs recovered from CMC cop…
  • Early impact of agropastoral activities and climate on the littoral landscape of Corsica since mid-Holocene. [Journal Article]
    PLoS One 2019; 14(12):e0226358Vella MA, Andrieu-Ponel V, … Ottaviani-Spella MM
  • A multidisciplinary study (geomorphology, sedimentology and palynology) shows that the landscapes of the southwest coast of Corsica have been deeply modified by humans and the climate since 3000 BC. Significant and rapid landscape transformations are recorded between the Chalcolithic and the Middle Bronze Ages (3000-1300 BC). Several major (2.2 ka BC, 1.2 ka BC) and local (3000 BC) detrital event…
  • Late Holocene vegetation responses to climate change and human impact on the central Tibetan Plateau. [Journal Article]
    Sci Total Environ 2020; 708:135370Ma Q, Zhu L, … Haberzettl T
  • Understanding long-term environmental changes under natural and anthropic forces is helpful for facilitating sustainable development. Here we present a sedimentary record from the central Tibetan Plateau to investigate the impacts of climate and human activities on alpine vegetation during the late Holocene, based on a 162-cm-long lacustrine sediment core collected from Tangra Yumco. Palynology, …
  • Postglacial change of the floristic diversity gradient in Europe. [Journal Article]
    Nat Commun 2019; 10(1):5422Giesecke T, Wolters S, … Brewer S
  • Climate warming is expected to cause a poleward spread of species, resulting in increased richness at mid to high latitudes and weakening the latitudinal diversity gradient. We used pollen data to test if such a change in the latitudinal diversity gradient occurred during the last major poleward shift of plant species in Europe following the end of the last glacial period. In contrast to expectat…
  • Volcanic mercury and mutagenesis in land plants during the end-Triassic mass extinction. [Journal Article]
    Sci Adv 2019; 5(10):eaaw4018Lindström S, Sanei H, … Outridge PM
  • During the past 600 million years of Earth history, four of five major extinction events were synchronous with volcanism in large igneous provinces. Despite improved temporal frameworks for these events, the mechanisms causing extinctions remain unclear. Volcanic emissions of greenhouse gases, SO2, and halocarbons are generally considered as major factors in the biotic crises, resulting in global…
