Genome comparison of 12 fruit fly species
Researchers from the UAB Genomics, Bioinformatics and Evolution Group participated in an international research that has resulted in the completion of the genomes of ten new fruit fly species. The study also includes new data on the evolution of the twelve currently known species during the past sixty million years. view more (2007-11-16)
Hermaphroditic plants have genetic advantage in areas where extinctions are frequent
In one of the first studies to empirically compare the reproductive success of hermaphrodites and male and female populations, biologists from the University of Oxford make use of the rare and extreme sexual diversity displayed in a species of European weed to test the hypothesis that hermaphrodites have been selected in regions with frequent... view more...

Seed banks preserve plant diversity
'Some seed gene banks contain more higher plant species per square meter than anywhere else on the planet', write Simon Linington and colleagues of the Millenium Seed Bank, Kew, in the October issue of Biologist. This helps to 'ensure plant diversity is available long term for use in development or habitat restoration', they explain. Although... view more... (2003-10-02)
Underestimation of frog numbers causes concern
Frogs are vanishing from all the world's ecosystems with unprecedented speed. It is thought that more than 100 species have died out since 1980 alone. view more (2007-10-31)
Invasives threaten salmon in Pacific Northwest
Many native fishes in the Pacific Northwest are threatened or endangered, notably salmonids, and hundreds of millions of dollars are expended annually on researching their populations and on amelioration efforts. view more (2009-03-02)
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)
Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. view more (2007-04-02)
Smaller plants punch above their weight in the forest, say Queen's biologists
New findings from Queen's University biologists show that in the plant world, bigger isn't necessarily better. view more (2009-07-15)
Not batty conservation
Noah had it easy. To weather the storm of impending disaster that would wipe-out life on earth, he simply protected a male and female of each species on the ark. Protecting contemporary biodiversity from the deluge of human activities that threaten life on earth is more difficult and requires a global network of reserves that includes all... view more...

11,000 alien species invade Europe
For the first time it is now possible to get a comprehensive overview of which alien species are present in Europe, their impacts and consequences for the environment and society. view more (2008-11-21)
Different coat color may not mean different species for lemurs
Researchers have found that lemurs suspected to belong to different species because of their strikingly different coat colors, are not only genetically alike, but belong to the same species. view more (2006-11-16)
Time series identify population responses to climate change
Biologists have for several years modeled how different species are likely to respond to climate change. Most such studies ignore differences between populations within a species and the interactions between species, in the interest of simplicity. view more (2009-06-01)
Rove beetles act as warning signs for clear-cutting consequences
New research from the University of Alberta and the Canadian Forest Service has revealed the humble rove beetle may actually have a lot to tell us about the effects of harvesting on forests species. view more (2007-06-13)
Online collaboration identifies bacteria
A new website has been launched which allows scientists everywhere to collaborate on the identification of bacterial strains. This new resource, described in the open access journal BMC Biology, provides a portal for electronic bacterial taxonomy. view more (2009-02-19)
Do you know what are you eating?
The project presented by Basque research center AZTI is about a new research line: a new method to identify the food and fish products once they are processed. Due to the big demand on that kind of researches, AZTI has been financed by the Fishing and Agricultural Department of the Basque Government to create a new laboratory of genetics. In fact,... view more... (2002-12-05)
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)
Your own private global warming
A group of researchers from the British Antarctic Survey have collected individuals from a wide range of species commonly found in Antarctic waters and subjected them to increasing levels of water temperature to learn how each species is prepared to cope with the conditions that they are likely to experience in the future. view more (2009-06-30)
Habitat loss and reserve network selection
What is the minimum combination of areas needed to protect at least one population of every species in a region? - This is a problem commonly addressed when aiming at cost-effective reserve networks. However, because the stress on reserve cost, the properties of the reserve-network for species persistence are often overlooked, typically resulting... view more... (2003-07-02)
Queen's marine biologist investigates aliens beneath the waves
Queen's University Belfast is appealing for help from the public in looking at ways to detect and stop the spread of marine aliens. view more (2008-06-17)
New life found in ancient tombs
Life has been discovered in the barren depths of Rome's ancient tombs, proving catacombs are not just a resting place for the dead. The two new species of bacteria found growing on the walls of the Roman tombs may help protect our cultural heritage monuments. view more (2008-09-25)
