Nondestructive Visualization Techniques Used To Image Ancient Fossils
2013-11-11 12:19:33

[ Watch the Video: Animation of Serial Transverse Section of Pinus pinea Cone ] American Journal of Botany New study integrates visualization techniques to examine 150-million-year-old plant fossils without damaging specimens By integrating high-resolution X-ray imaging (termed microCT), 3D image segmentation, and computer animation, a new study conducted by Carole Gee at the University of Bonn, Germany, demonstrates the visualization of fossils without destroying the material....

Christmas Trees Unchanged For Millions Of Years
2012-12-14 21:36:41

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal BMC Biology that the genome of conifers like spruce, pine, and fir have essentially remained the same for the past 100 million years. The team analyzed the genome of conifers and compared it to that of flowering plants. Both plant groups stem from the same acceptor, but diverged about 300 million years ago. They compared the genome macrostructure for 157 gene families present both in conifers...

Dramatic shifts in the planet's climate and geography over millions of years changed the course of evolutionary history for conifer trees, according to a Yale paper in the Proceedings of the National Academy of Sciences. Yale researchers examined the fossil record and genetic makeup of 489 out of more than 600 living conifer species and discovered that while most conifers belong to ancient lineages, most Northern Hemisphere species, including the majority of pines and spruces, appeared...

First Record Of 1 Million Year Old Pollinating Insects Discovered
2012-05-16 04:27:26

A new study, conducted at the European Synchrotron Radiation Facility (ERSF), details the first recorded cases of pollination by insects. Scientists discovered many insects coated in specks of pollen within two pieces of amber dating back to 110 to 105 million years ago in northern Spain. Amber is the only medium that can contain such highly detailed features such as pollination over millions of years. The team of international scientists includes Xavier Delclòs from the...

Cypress distribution reflects the breakup of Pangaea In classical mythology, the cypress tree is associated with death, the underworld and eternity. Indeed, the family to which cypresses belong, is an ancient lineage of conifers, and a new study of their evolution affords a unique insight into a turbulent era in the Earth´s history. During the geological era known as the Mesozoic, the continental crust was concentrated in a single huge landmass, the supercontinent Pangea. Pangea...

Sturdy Scandinavian Conifers Survived Ice Age
2012-03-04 05:52:45

[ Watch the Video] Until now, it was presumed that the last glacial period denuded the Scandinavian landscape of trees until a gradual return of milder weather began and melted away the ice cover some 9000 years ago. That perspective is now disproved by research headed by Professor Eske Willerslev from the Centre for GeoGenetics, University of Copenhagen, Denmark, Laura Parducci from the University of Uppsala, Sweden, and Inger Greve Alsos from Tromsø University Museum,...

Neiker-Tecnalia (the Basque Institute for Agricultural Research and Development) is working on the development of new biotechnological tools to produce in vitro selected trees of the Pinus genus. Scientists at this technological centre have developed various techniques for propagation of Pinus radiata, Pinus pinea, Pinus pinaster and Pinus sylvestris by using tissue culture. These methodologies enable obtaining a great quantity of clonal material, which can be used both in genetic improve...

Russia's boreal forest "“ the largest continuous expanse of forest in the world, found in the country's cold northern regions "“ is undergoing an accelerating large-scale shift in vegetation types as a result of globally and regionally warming climate. That in turn is creating an even warmer climate in the region, according to a new study published in the journal Global Change Biology and highlighted in the April issue of Nature Climate Change. The Great Russian forest, which...

New study of Clark's nutcrackers suggests that their caching of whitebark pine seeds is less effective than previously thought at restoring populations of the declining conifer The caching of whitebark pine seeds by the Clark's nutcracker in late summer and early fall may not be enough to regenerate populations of the imperiled conifer in most of its range, scientists have found. Their research"”which is featured in the February issue of Science Findings, a monthly publication of the...

From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere.  Also called angiosperms, they make up 90 percent of all land-based, plant life. New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming...

The Clark's Nutcracker (Nucifraga columbiana) is a large passerine bird in the family Corvidae. It is slightly smaller than its Eurasian relative, Spotted Nutcracker (N. caryocatactes). It is ashy-grey all over except for the black-and-white wings and central tail feathers (the outer ones are white). The bill, legs and feet are also black. This bird is found in western North America from British Columbia and western Alberta in the north to Baja California and western New Mexico in the...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
