Contrary to public perception, die-offs in honeybee colonies are an agricultural not a conservation issue, argue researchers, who say that manged honeybees may contribute to the genuine biodiversity crisis of Europe's declining wild pollinators.
A varied collection of lizards throughout Asia are unexpectedly close cousins of beach-dwelling mourning geckos, all descended from a common ancestor species that thrived along an ancient archipelago in the West Pacific that served as a 'superhighway' of biodiversity.
The early evolution of snakes happened from surface-terrestrial to burrowing in the lizard-snake transition suggests a research group.
Introduced predators pose threats to biodiversity and are implicated in the extinction of many native species.
A new fly species with bulging forelegs is named after former California governor and famous bodybuilder and actor Arnold Schwarzenegger. Measuring 0.395 mm in body length, it is also now the smallest known fly.
Researchers show how Argentine ants use chemical secretions as weapons in their interactions with harvester ants, which are native to California. The findings could help in the development of new pest control strategies.
Scientists are debating whether and why it appears that the number of species at sites worldwide is holding steady (even increasing at many), as biodiversity declines globally.
New study identifies conservation priorities based on evolutionary history and biogeography.
Is it possible to predict which nonnative plant species will become invasive weeds and when? According to new research, the answer is 'hopefully yes.' And those predictions can lead to more effective and cost-efficient weed management.
Growing in crocodile infested billabongs in the remote North of the country, Australia's wild rice has been confirmed as the most closely related to the ancient ancestor of all rices. The unique genetics of the Australian rice may help breed disease resistance and climate adaptation into rice modern production species.
A new study using playbacks, has for the first time shown that Asian elephants in Sri Lanka are scared of honey bees, much like their African counterparts. The study showed that Asian elephants responded with alarm to the bee simulations. They also retreated significantly further away and vocalized more in response to the bee sounds compared to controls.
Invasive species have diverse impacts in different locations, including biodiversity loss, as a result of native species being outcompeted for similar resources. A US research team studied the case of an aggressive Eurasian woodwasp that has recently established in North America and poses a threat to a native competitor species.
New research has revealed a surprising relationship between surging atmospheric carbon dioxide and flower blooms in a remote tropical forest.
A new study reveals that omnivorous New World noctilionoid bats, those species with diets including both plant and animal materials, produce more new species in the long run than specialized vegetarian or insectivorous species.
Planting 20 percent more trees in our megacities would double the benefits of urban forests, like pollution reduction, carbon sequestration and energy reduction. The authors of the study say city planners, residents and other stakeholders should start looking within cities for natural resources and conserve the nature in our urban areas by planting more trees.
Post-fire logging, rather than the wildfires themselves, is responsible for the steep decline in territory occupancy of the rare Spotted owls living in the forests of California. The study's results coincide with the strong consensus among hundreds of US scientists opposing post-fire logging operations due to a wide range of ecological harms.
Researchers have for the first time determined that hybridization between two bird species can give rise to several novel and fully functional hybrid genomic combinations. This could potentially be because hybrid species emerged through independent hybridization events between the same parent species on different islands.
According to Charles Darwin the ability to adapt to new conditions is essential for survival of species. The capacity to cope with altered conditions is becoming increasingly important in the face of climate change. New evidence on salt water tolerance in spawning migrating pike from the Baltic Sea suggests that not being adapted to specific local environments may promote persistence in an uncertain, rapidly changing world.
Though Michigan's sugar maples benefit from the growth-promoting effects of nitrogen compounds in the environment, those gains will not fully offset the added stresses of growing under a drier climate in the future, according to a new study.
Studies of island bird populations have taught us a lot about evolution, but it's hard to catch birds in the act of naturally colonizing new islands. Instead, a new study examines what's happened by looking at the genetics of a species that arrived in Hawaii in the twentieth century through decidedly unnatural means--us.
