Lascaux is a network of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations and, with continued debate, the age of the paintings is now usually estimated at around 17,000 years. Because of the outstanding prehistoric art in the cave, Lascaux was inducted into the UNESCO World Heritage List in 1979, as an element of the Prehistoric Sites and Decorated Caves of the Vézère Valley.
In archaeology, cave paintings are a type of parietal art, found on the wall or ceilings of caves. The term usually implies prehistoric origin, and the oldest known are more than 40,000 years old and found in the caves in the district of Maros. The oldest are often constructed from hand stencils and simple geometric shapes. More recently, in 2021, cave art of a pig found in Sulawesi, Indonesia, and dated to over 45,500 years ago, has been reported.
The Chauvet-Pont-d'Arc Cave in the Ardèche department of southeastern France is a cave that contains some of the best-preserved figurative cave paintings in the world, as well as other evidence of Upper Paleolithic life. It is located near the commune of Vallon-Pont-d'Arc on a limestone cliff above the former bed of the river Ardèche, in the Gorges de l'Ardèche.
The Upper Paleolithic is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago, according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic Revolution and agriculture.
Glomeromycota are one of eight currently recognized divisions within the kingdom Fungi, with approximately 230 described species. Members of the Glomeromycota form arbuscular mycorrhizas (AMs) with the thalli of bryophytes and the roots of vascular land plants. Not all species have been shown to form AMs, and one, Geosiphon pyriformis, is known not to do so. Instead, it forms an endocytobiotic association with Nostoc cyanobacteria. The majority of evidence shows that the Glomeromycota are dependent on land plants for carbon and energy, but there is recent circumstantial evidence that some species may be able to lead an independent existence. The arbuscular mycorrhizal species are terrestrial and widely distributed in soils worldwide where they form symbioses with the roots of the majority of plant species (>80%). They can also be found in wetlands, including salt-marshes, and associated with epiphytic plants.
Paleolithic Europe, or Old Stone Age Europe, encompasses the Paleolithic or Old Stone Age in Europe from the arrival of the first archaic humans, about 1.4 million years ago until the beginning of the Mesolithic around 10,000 years ago. This period thus covers over 99% of the total human presence on the European continent. The early arrival and disappearance of Homo erectus and Homo heidelbergensis, the appearance, complete evolution and eventual demise of Homo neanderthalensis and the immigration and successful settlement of Homo sapiens all have taken place during the European Paleolithic.
White-nose syndrome (WNS) is a fungal disease in North American bats which has resulted in the dramatic decrease of the bat population in the United States and Canada, reportedly killing millions as of 2018. The condition is named for a distinctive fungal growth around the muzzles and on the wings of hibernating bats. It was first identified from a February 2006 photo taken in a cave located in Schoharie County, New York. The syndrome has rapidly spread since then. In early 2018, it was identified in 33 U.S. states and seven Canadian provinces; plus the fungus, albeit sans syndrome, had been found in three additional states. Most cases are in the eastern half of both countries, but in March 2016, it was confirmed in a little brown bat in Washington state. In 2019, evidence of the fungus was detected in California for the first time, although no affected bats were found.
Geastrum is a genus of puffball-like mushrooms in the family Geastraceae. Many species are commonly known as earthstars.
The art of the Upper Paleolithic represents the oldest form of prehistoric art. Figurative art is present in Europe and Southeast Asia, beginning between about 40,000 to 35,000 years ago. Non-figurative cave paintings, consisting of hand stencils and simple geometric shapes, are somewhat older, at least 40,000 years old, and possibly as old as 64,000 years. This latter estimate is due to a controversial 2018 study based on uranium-thorium dating, which would imply Neanderthal authorship and qualify as art of the Middle Paleolithic.
Pseudogymnoascus destructans is a psychrophilic (cold-loving) fungus that causes white-nose syndrome (WNS), a fatal disease that has devastated bat populations in parts of the United States and Canada. Unlike species of Geomyces, P. destructans forms asymmetrically curved conidia. Pseudogymnoascus destructans grows very slowly on artificial media and cannot grow at temperatures above 20 °C. It can grow around 4 °C to 20 °C, which encompasses the temperatures found in winter bat hibernacula. Phylogenic evaluation has revealed this organism should be reclassified under the family Pseudeurotiaceae, changing its name to Pseudogymnoascus destructans.
The International Institute for Species Exploration (IISE) is a research institute located in Syracuse, New York. Its mission is to improve taxonomical exploration and the cataloging of new species of flora and fauna. Since 2008, IISE has published a yearly "Top 10" of the most unusual or unique biota newly identified in the previous year, with the aim of drawing attention to the work done in taxonomy across the world over the previous year.
Marine fungi are species of fungi that live in marine or estuarine environments. They are not a taxonomic group, but share a common habitat. Obligate marine fungi grow exclusively in the marine habitat while wholly or sporadically submerged in sea water. Facultative marine fungi normally occupy terrestrial or freshwater habitats, but are capable of living or even sporulating in a marine habitat. About 444 species of marine fungi have been described, including seven genera and ten species of basidiomycetes, and 177 genera and 360 species of ascomycetes. The remainder of the marine fungi are chytrids and mitosporic or asexual fungi. Many species of marine fungi are known only from spores and it is likely a large number of species have yet to be discovered. In fact, it is thought that less than 1% of all marine fungal species have been described, due to difficulty in targeting marine fungal DNA and difficulties that arise in attempting to grow cultures of marine fungi. It is impracticable to culture many of these fungi, but their nature can be investigated by examining seawater samples and undertaking rDNA analysis of the fungal material found.
Rock art has been produced in Europe since the Upper Palaeolithic period through to recent centuries. It is found in all of the major regions of the continent. One of the most famous examples of parietal art is the Grotte Chauvet in France. The cultural purpose of these remnants of the Paleolithic and other periods of prehistoric art is not known. However, some theories suggest that, because these paintings were created in parts of the caves that were not easily accessed, it is unlikely that they were intended simply as decoration.
Ochroconis anomala is a species of fungus of the Ascomycota group described in 2012. It was isolated from the black stains that appeared on the walls of Lascaux Cave in France. The species was discovered along with a closely related O. lascauxensis. The species are regarded as a threat to the prehistoric paintings of the cave.
Aspergillus ustus is a microfungus and member of the division Ascomycota. It is commonly found in indoor environments and soil. Isolated cases of human infection resulting from A. ustus have been described; however the majority of these are nail infections.
Geomyces pannorum is a yellow-brown filamentous fungus of the phylum Ascomycota commonly found in cold soil environments including the permafrost of the Northern hemisphere. A ubiquitous soil fungus, it is the most common species of the genus Geomyces; which also includes G. vinaceus and G. asperulatus. Geomyces pannorum has been identified as an agent of disfigurement of pigments used in the 15,000-year-old paintings on the walls of the Lascaux caves of France. Strains of Geomyces have been recovered from the Alaskan Fox Permafrost Tunnel and radiocarbon dated to between 14,000 and 30,000 years old.
Aspergillus tennesseensis is a species of fungus in the genus Aspergillus. It is from the Versicolores section. The species was first described in 2012.
The Deer Cave is a natural cave at the Salento coast near the town of Porto Badisco, around 8 km (5.0 mi) south of Otranto in Apulia, Italy. Unknown before 1970 it came to immediate international attention after the discovery of its impressive, innovative and enigmatic complex galleries of prehistoric parietal wall paintings.
Aspergillus turkensis is a species of fungus in the genus Aspergillus. It is from the Usti section. The species was first described in 2011. It has been isolated from soil in Turkey. It has been reported to produce an austocystin, deflectins, emerin, and a shamixanthone.
Fungal DNA barcoding is the process of identifying species of the biological kingdom Fungi through the amplification and sequencing of specific DNA sequences and their comparison with sequences deposited in a DNA barcode database such as the ISHAM reference database, or the Barcode of Life Data System (BOLD). In this attempt, DNA barcoding relies on universal genes that are ideally present in all fungi with the same degree of sequence variation. The interspecific variation, i.e., the variation between species, in the chosen DNA barcode gene should exceed the intraspecific (within-species) variation.
