Report shows deforestation threatens Brazil's Pantanal

...ies threatened with extinction, which depends on a tree commonly called 'manduvi' (Sterculia apetala) for shelter and reproduction. Without this specific tree, chances are that the hyacinth macaw will disappear. According to the report, urgent actions required to reverse the situation include increased g...

Honey helps problem wounds

...lepto-spermum honey'. Leptospermum is a species of tree which occurs in New Zealand and Australia. Honey from these trees has a particularly strong anti-bacterial effect, even in a 10% dilution. 'It is not yet known exactly why this is,' Dr. Arne Simon says. 'Probably it is a mix of phenol-type substances...

DOE JGI sequences, releases genome of symbiotic tree fungus

... changes that occur between the two genomes as the tree and the fungus collaborate to generate biomass. It also helps us to understand the interaction between these two symbionts within the context of the changing global climate." "Characterization of the interactions between poplar and its symbiotic as...

Primates take weather into account when searching for fruits

...ic (or "event-based") memories of whether or not a tree previously carried fruit, combined with knowledge of recent and present weather conditions and a more generalized understanding of the relationship between temperature and solar radiation and the maturation rate of fruit and insect larvae. The findin...

Beekeepers work hard for the honey, despite changing tupelo forest

...only along the Apalachicola. "It's the preferred tree for making tupelo honey," Stallins said, explaining that this type of honey does not granulate like many honeys. "The tupelo honey derived from forests with a greater concentration of white tupelo is more likely to have the complex floral flavor when...

Biologists find regions of rice domestication

...e the genetic signature of clusters on a haplotype tree (family tree)," explained Londo. "We chose samples across the entire range of rice and looked for DNA sequences that were shared by both wild and domesticated types. These two major groups clustered out by geography." DNA is comprised of vast, var...

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 ...

Acid rain causing decline in sugar maples, say researchers

... The sugar maple is the most economically valuable tree species in the eastern United States because of its high-priced lumber, syrup and tourist-attracting fall colors. The study, whose lead author, Stephanie Juice '04, was an undergraduate when the research was conducted, suggests that because acid r...

Tamed 11,400 years ago, figs were likely first domesticated crop

...resulting fruits do not produce new trees, and fig tree cultivation became a common practice," Bar-Yosef says. "In this intentional act of planting a specific variant of fig tree, we can see the beginnings of agriculture. This edible fig would not have survived if not for human intervention." Figs are ve...

New genetic analysis forces re-draw of insect family tree

The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects. Scientists have found that flies and moths are most closely related to ...

Mayo Clinic collaboration mining of ancient herbal text leads to potential new anti-bacterial drug
