New low-cost, nondestructive technology cuts risk from mercury hot spots

New low-cost, nondestructive technology cuts risk from mercury hot spots

Hot spots of mercury pollution in aquatic sediments and soils can contaminate local food webs and threaten ecosystems, but cleaning them up can be expensive and destructive. Researchers from the Smithsonian Environmental Research Center and the University of Maryland, Baltimore County have found a new low-cost, nonhazardous way to reduce the risk of exposure: using […]

Aboriginal hunting practice increases animal populations

Aboriginal hunting practice increases animal populations

In Australia’s Western Desert, Aboriginal hunters use a unique method that actually increases populations of the animals they hunt, according to a study co-authored by Stanford Woods Institute-affiliated researchers Rebecca and Doug Bird. Rebecca Bird is an associate professor of anthropology, and Doug Bird is a senior research scientist. The study, published today in Proceedings […]

Crimeea, amenintata de un dezastru ecologic din cauza armamentului chimic

Crimeea, amenintata de un dezastru ecologic din cauza armamentului chimic

  Peninsula Crimeea a intrat sub amenintare de dezastru ecologic, pentru ca autoritatile Ucrainei nu au adoptat la timp masurile necesare dezafectarii celor 60 de sarcofage din Marile Neagra si Azov, pline cu armament chimic, scrie sambata saptamanalul Zerkalo Nedeli, care apare la Kiev. Potrivit unui document semnat de director departamentului pentru securitate din cadrul […]

Increasing toxicity of algal blooms tied to nutrient enrichment and climate change

Increasing toxicity of algal blooms tied to nutrient enrichment and climate change

Nutrient enrichment and climate change are posing yet another concern of growing importance: an apparent increase in the toxicity of some algal blooms in freshwater lakes and estuaries around the world, which threatens aquatic organisms, ecosystem health and human drinking water safety. As this nutrient enrichment, or «eutrophication» increases, so will the proportion of toxin-producing […]

Испанский винодел получает разрешение на вырубку более 62 гектаров леса в Калифорнии

Испанский винодел получает разрешение на вырубку более 62 гектаров леса в Калифорнии

По мере роста и развития винодельческой промышленности Калифорнии виноделы ищут годящиеся районы выращивания винограда, но уже за пределами долины и ближе к побережью. А недавно стало известно, что испанская винодельческая компания Artesa Vineyards and Winery, с целью освобождения места для высадки новых виноградных лоз, подала заявку на приобретение и вырубку больше 62 гектаров прибрежной земли, […]

Coral itself may play important role in regulating local climate: Coral chemicals protect against warming oceans

Coral itself may play important role in regulating local climate: Coral chemicals protect against warming oceans

A new article reveals coral animals produce the ‘smell of the ocean’ — influencing cloud formation and protecting themselves against rising seawater temperatures. Australian marine scientists have found the first evidence that coral itself may play an important role in regulating local climate. They have discovered that the coral animal — not just its algal […]

Laureatii Premiului Nobel pentru Pace fac apel la eliminarea armelor nucleare

Laureatii Premiului Nobel pentru Pace fac apel la eliminarea armelor nucleare

Laureatii Premiului Nobel pentru Pace reuniti la Varsovia au facut apel miercuri la liderii de pe plan mondial sa negocieze un proces de eliminare ‘universala, legala si verificabila a armelor nucleare’ din lume, transmite Associated Press. Declaratia din finalul reuniunii anuale a laureatilor prestigiosului premiu indeamna totodata la lansarea de negocieri in vederea incheierii conflictelor […]

The molecular clock of the common buzzard: Influence of genes on dispersal behavior revealed

The molecular clock of the common buzzard: Influence of genes on dispersal behavior revealed

Be it hibernation or the routes of migratory birds: all animal behaviour that is subject to annual rhythms is controlled by a molecular clock. Although this has been known for a long time, in many cases it is still unclear how far genes are involved in setting this internal clock. Up to now, this also […]

How climate change affects microbial life below the seafloor

How climate change affects microbial life below the seafloor

Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years. For more than a decade scientists at the Max Planck Institute for Marine Microbiology and their colleagues at MARUM and the University of Aarhus […]

Более 300 слонов нашли отравленными в Национальном парке Зимбабве

Более 300 слонов нашли отравленными в Национальном парке Зимбабве

Как на днях заявила организация по охране дикой природы, более 300 слонов и других животных в Национальном парке Хванге (Зимбабве) погибли от рук браконьеров, которые отравили их цианидом. Первые погибшие животные, среди которых львы, грифы, пестрые собаки и гиены, были обнаружены группой охотников, которые пролетали над районом, ещё в июле. Но только недавно природоохранное ведомство […]
