Giant meat-eating plants prefer shrew poo

Botanists have discovered that the giant montane pitcher plant of Borneo has a pitcher the exact same size as a tree shrew's body.

Insect that fights Japanese knotweed to be released

A tiny Japanese insect that could help the fight against an aggressive superweed has been given the go-ahead for a trial release in England.

Cultivating new talent

Concerns about food shortages, land use, climate change and biodiversity have created a huge need for interdisciplinary researchers focused on agriculture. Virginia Gewin investigates the opportunities.

Biodiversity: Out of sight, out of mind

Once species disappear from the face of the Earth, they are quickly forgotten, says Samuel Turvey. In this week's Green Room, he warns that extinctions must be treated as a warning that human activities, such as overhunting and agriculture, are making the planet a poorer place to live.

Third seed shipment sent to Norway seed vault by USDA

ScienceDaily Botany News - Thu, 03/11/2010 - 00:00
A shipment of seed sent by the Agricultural Research Service earlier this month to the Svalbard Global Seed Vault in Norway included a wild Russian strawberry that an expeditionary team braved bears and volcanoes to collect.

Secrets of the Amazon: giant anacondas and floating forests, an interview with Paul Rosolie

Plant news from Mongabay - Wed, 03/10/2010 - 16:39
At twenty-two Paul Rosolie has seen more adventure than many of us will in our lifetime. First visiting the Amazon at eighteen, Rosolie has explored strange jungle ecosystems, caught anaconda and black caiman bare-handed, joined indigenous hunting expeditions, led volunteer expeditions, and hand-raised a baby giant anteater. "Rainforests were my childhood obsession," Rosolie told Mongabay.com. "For as long as I can remember, going to the Amazon had been my dream […] In those first ten minutes [of visiting], cowering under the bellowing calls of howler monkeys, I saw trails of leaf cutter ants under impossibly large, vine-tangled trees; a flock of scarlet macaws crossed the sky like a brilliant flying rainbow. I saw a place where nature was in its full; it is the most amazing place on earth."

Discovery in legumes could reduce fertilizer use, aid environment

ScienceDaily Botany News - Wed, 03/10/2010 - 14:00
Escalating use of nitrogen fertilizer is increasing algal blooms and global warming, but a recent discovery by researchers could begin to reverse that. They have revealed a key step in how symbiotic bacteria living in legumes turn nitrogen into plant food, which could be used to improve the process in some plants, reducing the need for chemical fertilizers.

Climate change and human influence

Plant news from BGCI - Wed, 03/10/2010 - 05:55
A Met Office review of the latest climate research confirms our planet is changing rapidly and man-made greenhouse gas emissions are very likely the cause. The changes follow the pattern of expected climate change and provide the clearest evidence yet that human activity is impacting our climate.

Plant hormone increases cotton yields in drought conditions

ScienceDaily Botany News - Wed, 03/10/2010 - 00:00
A naturally occurring class of plant hormones called cytokinins has been found to help increase cotton yields during drought conditions.

Asexual plant reproduction may seed new approach for agriculture

ScienceDaily Botany News - Tue, 03/09/2010 - 08:00
A scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture.

Plants discover the benefits of good neighbors in strategy against herbivores

ScienceDaily Botany News - Tue, 03/09/2010 - 00:00
Scandinavian scientists have discovered that a species of tree defends itself from herbivore attack by using chemicals emitted by neighboring plants. The study reveals how species of Birch tree absorb chemical compounds from neighboring Marsh tea plants, Rhondodendron tomentosum, in a unique "defense by neighbor strategy."

Alternative Energy Crops in Space

ScienceDaily Botany News - Mon, 03/08/2010 - 14:00
What if space held the key to producing alternative energy crops on Earth? That's what researchers are hoping to find in a new experiment on the International Space Station.

New energy source from the common pea: Scientists create a solar energy device from a plant protein structure

ScienceDaily Botany News - Mon, 03/08/2010 - 08:00
Isolating the minute crystals of the PSI super complex from the pea plant, a biochemistry researcher suggests these crystals can be illuminated and used as small battery chargers or form the core of more efficient man-made solar cells.

Geraniums could help control devastating Japanese beetle

ScienceDaily Botany News - Mon, 03/08/2010 - 00:00
Geraniums may hold the key to controlling the devastating Japanese beetle, which feeds on nearly 300 plant species and costs the ornamental plant industry $450 million in damage each year, according to scientists.

Complex co-dependency of microfungi and grass

ScienceDaily Botany News - Mon, 03/08/2010 - 00:00
Plants harbor many different microbes, fungi and bacteria that take advantage of their hosts. However, the host can also benefit from these little organisms, which are known as endophytes. Endophyte infections are common in the meadow fescue cultivars found in Finland, although the frequency varies considerably both between and within cultivars. European tall fescue cultivars, on the other hand, were found to be practically endophyte-free. The toxins produced by endophytes affect the pest-resistance of grass in many ways.

Deep sedimentation of acantharian cysts: a reproductive strategy?

ScienceDaily Botany News - Mon, 03/08/2010 - 00:00
Spore-like reproductive cysts of enigmatic organisms called acantharians rapidly sink from surface waters to the deep ocean in certain regions, according to new research. Scientists suspect that this is part of an extraordinary reproductive strategy, which allows juveniles to exploit a seasonal food bonanza.

Why seed dispersers matter, an interview with Pierre-Michel Forget, chair of the FSD International Symposium

Plant news from Mongabay - Sun, 03/07/2010 - 15:52
There are few areas of research in tropical biology more exciting and more important than seed dispersal. Seed dispersal—the process by which seeds are spread from parent trees to new sprouting ground—underpins the ecology of forests worldwide. In temperate forests, seeds are often spread by wind and water, though sometimes by animals such as squirrels and birds. But in the tropics the emphasis is far heavier on the latter, as Dr. Pierre-Michel Forget explains to mongabay.com. "[In rainforests] a majority of plants, trees, lianas, epiphytes, and herbs, are dispersed by fruit-eating animals. […] As seed size varies from tiny seeds less than one millimetres to several centimetres in length or diameter, then, a variety of animals is required to disperse such a continuum and variety of seed size, the smaller being transported by ants and dung beetles, the larger swallowed by cassowary, tapir and elephant, for instance."

Genetically engineered tobacco plant cleans up environmental toxin

ScienceDaily Botany News - Sat, 03/06/2010 - 17:00
Tobacco might become as well known for keeping us healthy as it is for causing illness thanks to researchers from the UK. In a new study, scientists explain how they developed a genetically modified strain of tobacco that helps temper the damaging effects of toxic pond scum, scientifically known as microcystin-LR which makes water unsafe for drinking, swimming or fishing.
