World's oldest living tree discovered in Sweden
The world's oldest recorded tree is a 9,550 year old spruce in the Dalarna province of Sweden. The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time.    view more (2008-04-17)

DO NOT HIDE FROM RAIN UNDER A FIRTREE
Russian scientists have found out that industrial contamination of atmosphere has more impact on flora and soil under the trees and the trees as such than on the space between the crowns. The study has been funded by the Russian Foundation for Basic Research and the President~s grant. We normally... view more (2000-12-15)

Revolutionary new findings about the history of trees and climate in Scandinavia
Scientists at Ume'å University in Sweden are putting forward an entirely new picture of climate change and the first immigration of trees following the last Ice Age. Research shows that 8,000-14,000 years ago the climate was considerably warmer than was previously thought. When it was at its... view more (2002-03-06)

Fluorescence microscopy reveals why some antifreeze proteins inhibit ice growth better than others
Antifreeze or "ice structuring" proteins - found in some fish, insects, plants, fungi and bacteria - attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death.   view more (2007-03-07)

UBC discovery unlocks tree genetics, gives new hope for pine beetle defense
UBC researchers have discovered some of the genetic secrets that enable pine and spruce trees to fight off pests and disease, uncovering critical new information about forests' natural defense systems.   view more (2008-01-15)

Limited climate tracking in European trees despite 10,000 years of postglacial warmth
The relative roles of environment and history as controls of large-scale species distributions is a crucial issue in biogeography and macroecology. In the forthcoming issue of Ecology Letters Svenning & Skov use bioclimatic modelling to show that among 55 native European tree species, 36 occupy... view more (2004-06-10)

Predetermined winners and losers in the Ice Age extinction game
The Quaternary ice ages caused severe decimation of the European tree flora. Of the diverse pre-Ice Age tree flora only a minority of the genera are still widespread in Europe. Most of the remainder have been lost altogether from the European flora and now only occurs in Asia and/or North America,... view more (2003-07-02)

Fires in far northern forests to have cooling, not warming, effect
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere.   view more (2006-11-17)

Human activity destroys species that the Ice Age could not
Forest clearance and animal overgrazing in the last 5,000 years have destroyed important tree species that had survived even the Ice Age. Dr Mick Frogley, Lecturer in Physical Geography at the University of Sussex, is one of a British research team exploring a site near Lake Ioannina in the Pindus... view more (2002-09-20)

Scattered nature of Wisconsin's woodlands could complicate forests' response to climate change
If a warmer Wisconsin climate causes some northern tree species to disappear in the future, it's easy to imagine that southern species will just expand their range northward as soon as the conditions suit them.   view more (2008-07-16)

Some plants may compensate for herbivore damage by stimulating nutrient release in the soil
Browsing by mammals often has a serious impact on the growth of tree saplings and the regeneration of forests. However, there is much uncertainty with regard to effects on soil nutrient cycling and in turn, potential consequences for the growth of plants. In a paper to be published in the June... view more (2004-05-13)

New study links Western wildfires to Atlantic Ocean surface temperatures
Western U.S. wildfires are likely to increase in the coming decades, according to a new tree-ring study led by the University of Comahue in Argentina and involving the University of Colorado at Boulder that links episodic fire outbreaks in the past five centuries with periods of warming sea surface... view more (2006-12-27)

Study: Rain forest insects eat no more tree species than temperate counterparts
A study initiated by University of Minnesota plant biologist George Weiblen has confirmed what biologists since Darwin have suspected-that the vast number of tree species in rain forests accounts for the equally vast number of plant-eating species of insects.   view more (2006-08-24)

Global warming greatest in past decade
Researchers confirm that surface temperatures in the Northern Hemisphere were warmer over the last 10 years than any time during the last 1300 years, and, if the climate scientists include the somewhat controversial data derived from tree-ring records, the warming is anomalous for at least 1700... view more (2008-09-02)

SRS Researchers Test Chinese Tallow Tree For Use in Building Materials
A preliminary study by USDA FS Southern Research Station (SRS) researchers and cooperators shows that Chinese tallow tree, a nonnative invasive plant in the southeastern United States, holds promise as a material for bio-based composite building panels.   view more (2006-07-26)

Ecological significance of tool-use in the woodpecker finch Cactospiza pallida
The Woodpecker finch, one of 14 Darwin`s finches of the Galapagos Islands, uses twigs or cactus spines to pry insects and spiders out of tree-holes. The advantage of using tools may seem evident, but empirical evidence is scarce. In a paper soon to appear in Ecology Letters, Tebbich and colleagues... view more (2002-09-09)

Dinsaurrific!
The most comprehensive picture yet of how dinosaurs evolved has been produced by a team at Bristol University. More than 1,000 species of dinosaurs have been named since the first skeletons were dug up in the 19th century, and unravelling their patterns of evolution has been a major area of... view more (2002-04-26)

Direct link established between tropical tree and insect diversity
Higher tree species diversity leads directly to higher diversity of leaf-eating insects.   view more (2006-07-19)

Subsidence: DNA profiling roots out offending trees
A new spinout company from the University of Leeds is laying claim to the most accurate identification of trees causing subsidence - using methods that could save the insurance industry millions in time and costs in disputed cases. Identi-Tree Ltd has been launched by the University's... view more (2004-04-26)

Fossil data plug gaps in current knowledge, study shows
Researchers have shown for the first time that fossils can be used as effectively as living species in understanding the complex branching in the evolutionary tree of life.   view more (2007-10-03)

Trees, forests and the Eiffel tower reveal theory of design in nature
What do a tree and the Eiffel Tower have in common? According to a Duke University engineer, both are optimized for flow. In the case of trees, the flow is of water from the ground throughout the trunk, branches and leaves, and into the air. The Eiffel Tower's flow carries stresses throughout the... view more (2008-08-14)

Kingston University Designer Delivers Christmas Tree Charity
A Kingston University designer is bringing some early Christmas cheer to hundreds of needy children. Tim Simpson, a third year student on the University's Product and Furniture Design course, has created an alternative Christmas tree for Save the Children's Festival of Trees. This festive... view more (2003-11-20)

Larger nuts end up further from tree
Trees are better off if they produce large nuts. This is revealed in research by Patrick Jansen from Wageningen University. Scatterhoarding rodents appear to prefer burying larger nuts for later. The bigger the nut, the further it is buried from the tree and the more frequently it is forgotten.... view more (2003-02-14)

Lizards shout against a noisy background to get points across
Male Anole lizards signal ownership of their territory by sitting up on a tree trunk, bobbing their heads up and down and extending a colorful throat pouch.   view more (2007-02-26)

Abertay scientist sets out to find undiscovered yeast
A University of Abertay Dundee scientist has braved scorching temperatures in harsh deserts to track down a new strain of "killer yeast" which could be used in agriculture and beer brewing. With a grant from NATO, Dr Graeme Walker recently flew out to Morocco to locate the Argan tree, a hardy plant... view more (2002-05-03)
