A user‐friendly method to get automated pollen analysis from environmental samples

Betty Gimenez, Sébastien Joannin, Jérôme Pasquet, Luc Beaufort, more

Automated pollen analysis is not yet efficient on environmental samples containing many pollen taxa and debris, which are typical in most pollen‐based studies. Contrary to classification, detection remains overlooked although it is the first step from which errors can propagate. Here, we investigated a simple but efficient method to automate pollen detection for environmental samples, optimizing...

The Discovery of Wild Date Palms in Oman Reveals a Complex Domestication History Involving Centers in the Middle East and Africa

Muriel Gros-Balthazard, Marco Galimberti, Athanasios Kousathanas, Claire Newton, more

Current Biology > 2017 > 27 > 14 > 2211-2218.e8

For many crops, wild relatives constitute an extraordinary resource for cultivar improvement [1, 2] and also help to better understand the history of their domestication [3]. However, the wild ancestor species of several perennial crops have not yet been identified. Perennial crops generally present a weak domestication syndrome allowing cultivated individuals to establish feral populations difficult...

Inferring the agrobiodiversity of Vitis vinifera L. (grapevine) in ancient Greece by comparative shape analysis of archaeological and modern seeds

Clémence Pagnoux, Laurent Bouby, Sarah Ivorra, Christophe Petit, more

Vegetation History and Archaeobotany > 2015 > 24 > 1 > 75-84

The origins and biogeographical history of Vitis vinifera L. (domesticated grapevine) remain largely unknown. Shape and size have long been used as criteria to distinguish between wild and domesticated grape pips. Here we have analyzed variations of seed morphology in order to provide accurate criteria for the discrimination of different groups of varieties. Diversity in present-day cultivars and...

New insights into Mediterranean Gallo-Roman farming: a closer look at archaeological wells in Southern France

Isabel Figueiral, Hervé Pomarèdes, Mona Court-Picon, Laurent Bouby, more

Archaeological and Anthropological Sciences > 2015 > 7 > 2 > 201-233

Archaeological wells have recently become a major source of palaeoenvironmental and palaeoeconomic information, thus, providing the background for past day-to-day material life. At the site of La Lesse–Espagnac (Hérault), combined evidence from archaeobotany, morphometry and palynology, from two wells, offers a coherent picture of the diversity of the local Gallo-Roman farming economy, whose development...

Impact of post-depositional processes on charcoal fragmentation and archaeobotanical implications: experimental approach combining charcoal analysis and biomechanics

Julia Chrzazvez, Isabelle Théry-Parisot, Gilbert Fiorucci, Jean-Frédéric Terral, more

Journal of Archaeological Science > 2014 > 44 > Complete > 30-42

Generally speaking, charcoal analysis is based on identifying and counting charcoal fragments in order to calculate the relative variations in taxa frequency. All post-depositional processes are likely to induce fragmentation of the anthracological material, raising the question of the representativeness of taxa. Based on an innovative experimental approach combining both charcoal analysis and biomechanics,...

On the origins and spread of Olea europaea L. (olive) domestication: evidence for shape variation of olive stones at Ugarit, Late Bronze Age, Syria—a window on the Mediterranean Basin and on the westward diffusion of olive varieties

Claire Newton, Christine Lorre, Caroline Sauvage, Sarah Ivorra, more

Vegetation History and Archaeobotany > 2014 > 23 > 5 > 567-575

Charred archaeological stones of Olea europaea L. (olive) from Late Bronze Age Ugarit, Syria, were analyzed with geometric morphometry and compared with a morphological differentiation model established on the basis of analyses of modern spontaneous (uncultivated) olive populations and cultivated varieties of various origins within the Mediterranean Basin. The results allow a reinterpretation of the...

Palaeobiogeography of Pinus nigra Arn. subsp. salzmannii (Dunal) Franco in the north-western Mediterranean Basin: A review based on macroremains

Paul Roiron, Lucie Chabal, Isabel Figueiral, Jean- Frédéric Terral, more

Review of Palaeobotany and Palynology > 2013 > 194 > Complete > 1-11

The palaeobiogeography of Pinus nigra subsp. salzmannii is investigated in an attempt to understand the environmental mechanisms responsible for its present-day fragmented distribution. A synthesis of data based on cone imprints from travertine deposits and wood charcoal from archaeological sites suggests that, in the past (Holocene), P. nigra subsp. salzmannii had a larger distribution in the north-western...

David Kaniewski, Elise Van Campo, Tom Boiy, Jean‐Frédéric Terral, more

Biological Reviews > 87 > 4 > 885 - 899

Our knowledge of the origins of olive tree domestication in the Middle East and on the processes governing its extension and persistence in different vegetation types from prehistory through antiquity to modern times derives from diverse sources, spanning the biological sciences to the humanities. Nonetheless, it lacks a robust overview that may lead to floating interpretations. This is especially...

Holocene upper tree-limits of Pinus section sylvestris in the Western Alps as evidenced from travertine archives

Nicolas Fauvart, Adam A. Ali, Jean-Frédéric Terral, Paul Roiron, more

Review of Palaeobotany and Palynology > 2012 > 169 > Complete > 96-102

The postglacial dynamics of Pinus sylvestris, Pinus mugo and Pinus uncinata are poorly documented in the Alps due to a lack of precise taxonomic resolution. We present past altitudinal distribution of these pine species, at a local scale, based on morphometric and taxonomic analyses of fossil cone imprints preserved in travertine deposits from the mountain and subalpine belt in the Western Alps. We...

Assessing past agrobiodiversity of Prunus avium L. (Rosaceae): a morphometric approach focussed on the stones from the archaeological site Hôtel-Dieu (16th century, Tours, France)

Pauline Burger, Jean-Frederic Terral, Marie-Pierre Ruas, Sarah Ivorra, more

Vegetation History and Archaeobotany > 2011 > 20 > 5 > 447-458

Abundant and diverse Prunus fruitstone remains from cherries, plums, sloes, peaches, etc. are frequently recovered from archaeological waterlogged contexts such as wells, latrines, lake dwellings etc. in Europe. The distinction between most of the Prunus species, based on traditional morphological characters of the fruit stones, is usually not problematic. However the discrimination between P. avium...

The origins of the domestication of the olive tree

Catherine Breton, Jean-Frédéric Terral, Christian Pinatel, Frédéric Médail, more

Comptes rendus - Biologies > 2009 > 332 > 12 > 1059-1064

The present diversity of the olive (crop) and oleaster (wild) tree was investigated with nuclear and cytoplasm markers. Patterns of diversity of the wild form inferred eleven ancestral populations in the East and the West of the Mediterranean basin. Patterns of diversity for cultivars are less clear, but we showed that cultivars admixed to nine groups that corresponded to oleaster ancestral populations...

A new, isolated and endangered relict population of dwarf pine (Pinus mugo Turra) in the northwestern Alps

Christopher Carcaillet, Nicolas Fauvart, Paul Roiron, Jean-Frédéric Terral, more

Comptes rendus - Biologies > 2009 > 332 > 5 > 456-463

Dwarf pines were discovered in 2004 during a paleoecological survey in the Mont Cenis massif (Savoy, France). These dwarf pines are the sole natural and spontaneous population in the NW French Alps of Pinus mugo Turra, ssp. mughus (Scop.) O. Schwarz. The population, fragile in light of the individual numbers, is currently isolated, but likely results from populations that would have covered larger...

Holocene hydrological and vegetation changes in southern France inferred by the study of an alluvial travertine system (Saint-Guilhem-le-Désert, Hérault)

Adam Ahmed Ali, Paul Roiron, Lucie Chabal, Paul Ambert, more

Comptes rendus - Geoscience > 2008 > 340 > 6 > 356-366

A geobotanical study of the travertine system of Saint-Guilhem-le-Désert (southern France) was carried out in order to reconstruct the local Holocene environment in a region where the postglacial vegetation history is poorly documented. The travertinisation process has started at ca. 8500 cal. BP, in a landscape dominated by Pinus sylvestris type (probably Pinus nigra sub sp. salzmannii). Around 7000...
