Secondary Growth in Vertebraria Roots from the Late Permian of Antarctica: A Change in Developmental Timing
(The University of Chicago Press, 2009-06-01)Permineralized Vertebraria roots from the late Permian of the Central Transantarctic Mountains, Antarctica, are investigated to understand the unusual vascular anatomy of the genus. The specimens range from ∼1 mm to several ... -
Evolution and Relationships of the Conifer Seed Cone Telemachus: Evidence from the Triassic of Antarctica
(University of Chicago Press, 2010-06-01)The seed cone Telemachus is known from several Triassic localities in Gondwana. New specimens from two localities in Antarctica provide additional information about the type species, Telemachus elongatus, based on details ... -
Macrofossil Evidence For Pleuromeialean Lycophytes From the Triassic of Antarctica
(Polska Akademia Nauk, Instytut Paleobiologii, 2010)Triassic microfloras from Antarctica contain abundant lycophyte spores. However, macrofossils of this group of plants are missing, and thus the precise affinities of the spore producers remain unknown. Macrofossil remains ... -
Systematics and Paleoecology of a New Peltaspermalean Seed Fern From the Triassic Polar Vegetation of Gondwana
(University of Chicago Press, 2011)A new Triassic seed fern is described on the basis of a large collection of well-preserved plant compressions from the Upper Triassic of Mt. Falla, Queen Alexandra Range, central Transantarctic Mountains. The foliage is ... -
The Possible Pollen Cone of the Late Triassic Conifer Heidiphyllum/Telemachus (Voltziales) From Antarctica
(Cambridge University Press, 2011)Fossil leaves of the Voltziales, an ancestral group of conifers, rank among the most common plant fossils in the Triassic of Gondwana. Even though the foliage taxon Heidiphyllum has been known for more than 150 years, our ... -
Morphological and Functional Stasis in Mycorrhizal Root Nodules as Exhibited by a Triassic Conifer
(National Academy of Sciences, 2011)Mycorrhizal root nodules occur in the conifer families Araucariaceae, Podocarpaceae, and Sciadopityaceae. Although the fossil record of these families can be traced back into the early Mesozoic, the oldest fossil evidence ... -
Triassic Leech Cocoon From Antarctica Contains Fossil Bell Animal
(National Academy of Sciences, 2012)Our understanding of the evolution of life on Earth is limited by the imperfection of the fossil record. One reason for this imperfect record is that organisms without hard parts, such as bones, shells, and wood, have a ... -
Oldest Fossil Basidiomycete Clamp Connections
(Springer Verlag, 2011)A rachis of the fossil filicalean fern Botryopteris antiqua containing abundant septate hyphae with clamp connections is preserved in a late Visean (Mississippian; *330 Ma) chert from Esnost (Autun Basin) in central France. ... -
Acaulosporoid glomeromycotan spores with a germination shield from the 400-million-year-old Rhynie chert
(Springer, 2009)Scutellosporites devonicus from the Early Devonian Rhynie chert is the only fossil glomeromycotan spore taxon known to produce a germination shield. This paper describes a second type of glomeromycotan spore with a germination ... -
Epicormic Schoots in a Permian Gymnosperm from Antarctica
(University of Chicago Press, 2010)Two anatomically preserved gymnosperm trunks with clusters of epicormic shoots are described from the Late Permian of Antarctica. The best-preserved trunk is 14 cm long. It has a small circular parenchymatous pith and 9 ... -
Dordrechtites Arcanus Sp. Nov., An Anatomically Preserved Gymnospermous Reproductive Structure From the Middle Triassic of Antarctica
(University of Chicago Press, 2013)The genus Dordrechtites is an isolated ovulate structure previously described only from South Africa and Australia as impressions. The discovery of compressed and permineralized specimens of this taxon at the base of Mount ... -
The Fossil Record of the Peronosporomycetes (Oomycota)
(Mycological Society of America, 2011)Evidence of fossil Peronosporomycetes has been slow to accumulate. In this review various fossils historically assigned to the Peronosporomycetes are discussed briefly and an explanation is provided as to why the fossil ... -
The First Permineralized Microsporophyll of the Glossopteridales: Eretmonia macloughlinii sp. nov.
(University of Chicago Press, 2012)Eretmonia du Toit is a microsporophyll genus attributed to the Permian Glossopteridales. Microsporophylls are scale leaves (smaller leaves with morphology similar to that of Glossopteris leaves) that bear clusters of sporangia ... -

The Big Questions For Biodiversity Informatics
(Taylor & Francis, 2010)Science is a sequence of generating new ideas, detailed explorations, incorporation of the results into a toolbox for understanding data, and turning them into useful knowledge. One recent development has been large-scale, ... -
Ecological niche shifts and environmental space anisotropy: a cautionary note
(Instituto de Biología, 2011)The anisotropic structure of climatic space may cause significant (and to a large extent unappreciated) nonevolutionary niche shifts. This can be seen mostly in the context of spatial transferability of ecological niche ... -
Occupation of environmental and morphological space: climatic niche and skull shape in Neotoma woodrats
(Evolutionary Ecology, 2012)Background: Theoretical and empirical studies suggest that in some circumstances niche evolution may be very slow – a phenomenon called ‘niche conservatism’. Evidence for niche conservatism comes mainly from studies of ... -
Order and Disorder in Modern Britain: Essays on Riot, Crime, Policing and Punishment
(Breviary Stuff Publications, 2014)The pieces in this collection range from an account of the Skeleton Army riots against the Salvation Army in the early 1880s to the unsuccessful campaign to abolish the death penalty in the aftermath of the Second World ... -

Trans-Pacific Partnership or Trampling Poor Partners? A Tentative Critical Review
(Manchester Journal of International Economic Law, 2014-04)The Trans-Pacific Partnership (TPP) could be the most economically and politically significant free trade agreement (FTA) in the Asia-Pacific region. Conceived in 2006 by just four small countries, it now embraces 12 that ...
