Mixed bacterial communities evolve to share resources, not compete

Mixed bacterial communities evolve to share resources, not compete

New research shows how bacteria evolve to increase ecosystem functioning by recycling each other's waste. The study provides some of the first evidence for how interactions between species shape evolution when there is a diverse community. Predicting how species and ecosystems will respond to new environments is an important task for biology. However, most studies [...]

Adirondack lakes in North Eastern US lose ice cover as climate warms: Most pristine lake marks biggest change

Adirondack lakes in North Eastern US lose ice cover as climate warms: Most pristine lake marks biggest change

Lakes in the undeveloped High Peaks area of the Adirondack Park are covered with ice for significantly shorter periods than they were 32 years ago, providing evidence that climate change is occurring rapidly and that not even the most pristine wilderness areas are immune. Since 1975, five high-elevation lakes in the Adirondacks have had rapid [...]

Dry rivers, vibrant with culture and life

Dry rivers, vibrant with culture and life

When the River Runs Dry' is a familiar song in Australia. Some rivers in the arid center of the continent flow only after a stiff monsoon season, and smaller tributaries all over the country commonly shrink to puddled potholes and dry river beds during the dry season. But rivers also run dry in more temperate [...]

Endangered species, languages linked at high biodiversity regions

Endangered species, languages linked at high biodiversity regions

Biodiversity hot spots -- the world's biologically richest and most threatened locations on Earth -- and high biodiversity wilderness areas -- biologically rich but less threatened -- are some of the most linguistically diverse regions on our planet, according to a team of conservationists. "Results indicate that these regions (hot spots and high biodiversity wilderness [...]

Gaseous emissions from dinosaurs may have warmed prehistoric Earth

Gaseous emissions from dinosaurs may have warmed prehistoric Earth

Sauropod dinosaurs could in principle have produced enough of the greenhouse gas methane to warm the climate many millions of years ago, at a time when Earth was warm and wet. That's according to calculations reported in the May 8th issue of Current Biology, a Cell Press publication. The hulking sauropods, distinctive for their enormous [...]

Potentialele efecte ale cutremurelor nu sunt suficient analizate in testele nationale de rezistenta pentru centrala nucleara de la Cernavoda. Recent Comisia Europeana a prezentat rapoartele de evaluare [...]

Different recipes for success in the world of plants

Different recipes for success in the world of plants

In order to prevail against native plants, non-native plant species develop special strategies. These differ in part considerably from the propagation strategies of endemic plant species. Dr. Ingolf Kühn and Dr. Sonja Knapp of the Helmholtz Centre for Environmental Research (UFZ) reached this conclusion in a study published in the current issue of the scientific [...]

Plant diversity is key to maintaining productive vegetation

Plant diversity is key to maintaining productive vegetation

Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present, results of a new study show. The long-term study of plant biodiversity found that each species plays a role in maintaining a productive ecosystem, especially when a long time horizon is [...]

Симптомы заболевания поджелудочной железы

Симптомы заболевания поджелудочной железы

Симптомы заболевания поджелудочной железы проявляются сходными показателями, такими как боли, диспептические расстройства (рвота, тошнота), понижение веса, немотивированное существенное понижение либо повышение голода. Заболевание поджелудочной железы бывает первичными и вторичными, так как  они появляются в итоге болезней печени, желудка, двенадцатиперстной кишки, желчевыводящих путей, после операций на органах пищеварительной системы. Среди изначальных болезней, которым подвергается сама поджелудочная [...]
