Peronosporomycetes (Oomycota) from a Middle Permian Permineralised Peat within the Bainmedart Coal Measures, Prince Charles Mountains, Antarctica
The fossil record of Peronosporomycetes (water moulds) is rather sparse, though their distinctive ornamentation means they are probably better reported than some true fungal groups. Here we describe a rare Palaeozoic occurrence of this group from a Guadalupian (Middle Permian) silicified peat deposit in the Bainmedart Coal Measures, Prince Charles Mountains, Antarctica. Specimens are numerous a...
متن کاملAge-related environmental gradients influence invertebrate distribution in the Prince Charles Mountains, East Antarctica
The potential impact of environmental change on terrestrial Antarctic ecosystems can be explored by inspecting biodiversity patterns across large-scale gradients. Unfortunately, morphology-based surveys of Antarctic invertebrates are time-consuming and limited by the cryptic nature of many taxa. We used biodiversity information derived from high-throughput sequencing (HTS) to elucidate the rela...
متن کاملThe fossil record of the Peronosporomycetes (Oomycota).
Evidence of fossil Peronosporomycetes has been slow to accumulate. In this review various fossils historically assigmed to the Peronosporomycets are dicussed briefly and an explanation is provided as to why the fossil record of this grouop has remained inconsistent. In recent year there has been several new reports of fossil peronosporomycetes based on structurally preserved oogonium-antheridiu...
متن کاملPhylogeny of the Peronosporomycetes ( Oomycota ) based on partial sequences of the large ribosomal subunit ( LSU rDNA )
The phylogeny of the nuclear large ribosomal subunit (LSU) rDNA from Peronosporomycetes (Oomycota) was studied. Five orders Rhipidiales, Leptomitales, Saprolegniales, Pythiales and Peronosporales were included in the study in order to reveal phylogenetic relationships within the group. Based on maximum parsimony, neighbour-joining and maximum-likelihood the Peronosporomycetes seem to have evolv...
متن کاملThe Permian–Triassic boundary in Antarctica
The Permian ended with the largest of known mass extinctions in the history of life. This signal event has been difficult to recognize in Antarctic non-marine rocks, because the boundary with the Triassic is defined by marine fossils at a stratotype section in China. Late Permian leaves (Glossopteris) and roots Vertebraria), and Early Triassic leaves (Dicroidium) and vertebrates (Lystrosaurus) ...
