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)

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)

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)

Important gene controlling tree growth and development found
Scientists at the UmeĆå Plant Science Centre (UPSC) and the Swedish University of Agricultural Sciences (SLU) report today about a breakthrough in our understanding of how the growth and development of forest trees is controlled.   view more (2006-05-05)

Forests damaged by Katrina may contribute to global warming
Researchers led by biologist Jeffrey Chambers of Tulane University have determined that the losses inflicted by Hurricane Katrina on Gulf Coast forest trees are enough to cancel out a year's worth of new tree biomass (trunks, branches and foliage) growth in other parts of the country.   view more (2007-11-16)

NASA satellites can see how climate change affects forests
A NASA-funded study shows that satellites can track the growth and health of forests and detect the impact of a changing climate on them.   view more (2006-08-30)

Scientists discover that ancient genes dictate flowering, fall bud set
It often requires many years of growth before a tree is ready to flower - a delay that makes tree breeders impatient. Now, scientists at universities in Sweden and the United States have discovered genes that are responsible for initiation of flowering.   view more (2006-05-05)

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)

Discovery May Speed Tree Breeding, Biotechnology
Researchers have discovered the genetic controls that cause trees to stop growing and go dormant in the fall, as well as the mechanism that causes them to begin flowering and produce seeds — a major step forward in understanding the basic genetics of tree growth.   view more (2006-06-01)

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)

Can you rescue a rainforest? The answer may be yes
Half a century after most of Costa Rica's rainforests were cut down, researchers from the Boyce Thompson Institute took on a project that many thought was impossible - restoring a tropical rainforest ecosystem.   view more (2008-03-28)

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)

Discovery of the genetic basis of two diseases
In a first article, Loeys et al describe a new aortic aneurysm syndrome characterized by the main triad of hypertelorism, bifid uvula and/or cleft palate and aortic aneurysms with arterial tortuosity. This new entity also presents with alterations of the skeletal, craniofacial, neurocognitve... view more (2005-03-17)

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)

Extinction most likely for rare trees in the Amazon rainforest
Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science.    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)

Diverse tropical forests defy metabolic ecology models
As global change accelerates, quantifying the role of forests in the carbon cycle becomes ever more urgent. Modelers seek simple predictors of forest biomass and carbon flux.   view more (2006-04-24)

Loss of Hemlocks Will Affect Water Dynamics in Southern Appalachian Forests
Forest Service (FS) research has provided the first estimates on the impact the loss of eastern hemlock will have on the water dynamics of the southern Appalachian mountains.   view more (2007-07-10)

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)
