Why the Amazon rainforest is so rich in species
Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain. view more (2005-12-06)
Bright white beetle dazzles scientists
An obscure species of beetle could teach us how to produce brilliant white ultra-thin materials, according to a research team led by the University of Exeter. view more (2007-01-19)
Global warming increases species extinctions worldwide
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist. view more (2006-11-15)
Scientists discover dozens of new species in Lost World of western New Guinea
An expedition to one of Asia's most isolated jungles - in the mist-shrouded Foja Mountains of western New Guinea - discovered a virtual 'Lost World of new species, giant flowers, and rare wildlife that was unafraid of humans. view more (2006-02-07)
Where Have All the Butterflies Gone?
Cold, wet conditions early in the year mean that 2006 is shaping up as the worst year for California's butterflies in almost four decades. view more (2006-05-09)
Butterflies lose body fat during metamorphosis
A group of scientists from Oregon have discovered that butterflies experience a great loss in body fat during metamorphosis. view more (2006-03-21)
Insect population growth likely accelerated by warmer climate
Insects have proven to be highly adaptable organisms, able through evolution to cope with a variety of environmental changes, including relatively recent changes in the world's climate. But like something out of a scary Halloween tale, new University of Washington research suggests insects' ability to adapt to warmer temperatures carries an... view more... (2006-10-31)
New, rare and threatened species discovered in Ghana
Scientists exploring one of the largest remaining blocks of tropical forest in Western Africa discovered significant populations of new, rare and threatened species underscoring the area's high biological diversity and value. view more (2007-12-07)
How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid. view more (2006-09-26)
New theory -- universal intelligence on animals and plants
Here it is proposed that life in all its variety is full of sensation and creates a complicated web of interaction with its surroundings. Mammals, birds and even fish mourn for a lost love. Single-celled organisms carry out tasks that are surprisingly complicated. We can demonstrate sensitivity in microscopic organisms, while plants emerge as... view more... (1999-03-25)
How does one sex grow larger than the other?
Why are males larger than females in some animal species (such as most mammals), females larger than males in others (such as most insects), and why are the sexes alike in yet other species (such as several birds)? view more (2007-01-30)
War between the sexes influences evolution in some species, say scientists
Competition and conflict between males and females start inside the egg in some species, say scientists. view more (2006-04-07)
New discovery: Molecular variation in one gene affects the growth of natural populations
For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat. view more (2006-04-26)
Butterfly speciation event recreated
In a matter of months, butterflies sporting the yellow and red wing color pattern of a wild species were created through simple laboratory crosses of two other wild species, researchers report in the June 15, 2006 edition of the journal Nature. view more (2006-06-15)
Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among the world's scientists for over ten years. John... view more... (2004-03-18)
Environmental effects on genetic adaptation and population dynamics
It seems intuitive that genes are affected by selection as a result of environment. In fact there is little evidence thus far that such genetic effects impact year-to-year population dynamics. view more (2006-04-25)
Food for Flight: Monarch Butterfly Migration and Forest Restoration
USDA Forest Service (FS) research in the Ouachita Mountains of Arkansas suggests that decades of fire suppression have reduced the area's food supply for migrating monarch butterflies-and that restoration efforts that include prescribed burning can reverse this trend. view more (2006-11-20)
Cougar predation key to ecosystem health
The general disappearance of cougars from a portion of Zion National Park in the past 70 years has allowed deer populations to dramatically increase, leading to severe ecological damage, loss of cottonwood trees, eroding streambanks, and declining biodiversity. view more (2006-10-25)
New study uncovers secrets behind butterfly wing patterns
The genes that make a fruit fly's eyes red also produce red wing patterns in the Heliconius butterfly found in South and Central America, finds a new study by a UC Irvine entomologist. view more (2007-10-26)
Climate warming and habitat loss threaten British Butterfly survival
Because butterflies are cold blooded, their growth and development are closely dependent on the weather and climate. When climates change insects can either shift breeding distributions to track it, stay put and adapt, or die out. Since the 1970s, climate warming in Britain has seen almost 20% of butterflies spread their ranges northwards,... view more... (2003-06-05)
