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 issue of Ecology Letters, researchers from Lancaster... 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 less than 50% of their climatically suitable... view more...

Long-term study of orchard ground cover management systems
Orchard floor and groundcover management is important to fruit growers, affecting the efficiency of orchard operations, fruit tree performance, and soil quality.   view more (2009-02-27)

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, although some persist as relicts in southern... view more... (2003-07-02)

Application quantifies carbon sequestration of urban trees
U.S. Forest Service scientists at the Center for Urban Forest Research are providing online software that can show users how much carbon dioxide an urban tree in California has sequestered in its lifetime and the past year.   view more (2008-12-10)

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 Mountains of northwestern Greece. "Given the... 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)

Tea tree oil and silver together make more effective antiseptics
In the fight against infected skin wounds, mixing tea tree oil and silver or putting them in liposomes, (small spheres made from natural lipids), greatly increases their antimicrobial activity and may minimise any side effects.   view more (2009-03-30)

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)

The first gene-encoded amphibian toxin isolated
Researchers in China have discovered the first protein-based toxin in an amphibian -a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison.   view more (2009-08-18)

California study shows shade trees reduce summertime electricity use
A recent study shows that shade trees on the west and south sides of a house in California can reduce a homeowner's summertime electric bill by about $25.00 a year.   view more (2009-01-06)

Neon blue-tailed tree lizard glides like a feather
Most lacertid lizards are content scurrying in and out of nooks and crannies in walls and between rocks. However, some have opted for an arboreal life style.   view more (2009-07-17)

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 years.   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 present the first study on the ecological... 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 research. Since 1980, over 150 evolutionary trees of... view more... (2002-04-26)
