Tracking marine food sources

Tracking marine food sources

To address the issue of tracing the source of amino acids, Dr. Thomas Larsen of “The Future Ocean” collaborated with researchers from California and Alaska to develop a method that from very small amount of samples can determine where animals obtain these essential nutrients. They discovered that all life forms leave traces or ‘fingerprints’ in […]

First global snapshot of key coral reef fishes: Fishing has reduced vital seaweed eaters by more than 50 percent

First global snapshot of key coral reef fishes:  Fishing has reduced vital seaweed eaters by more than 50 percent

In the first global assessment of its kind, a science team led by researchers at Scripps Institution of Oceanography at UC San Diego has produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs. The report, published in the journal Proceedings of the […]

Ученые в Финляндии разработали новый метод мониторинга обезлесения в тропических регионах

Ученые в Финляндии разработали новый метод мониторинга обезлесения в тропических регионах

Для такого, чтобы остановить нелегальную вырубку леса в тропических регионах, необходимо проводить постоянный мониторинг состояния лесного хозяйства. Именно для этих целей Центр технических изучений Финляндии (VTT) разработал новый способ точной оценки тропического лесного покрова на основе изображений, полученных со спутника. В проекте под наименованием ReCover, который является частью седьмой рамочной программы Евросоюза REDD, используются спутниковые […]

Five distinct humpback whale populations identified in North Pacific

Five distinct humpback whale populations identified in North Pacific

The first comprehensive genetic study of humpback whale populations in the North Pacific Ocean has identified five distinct populations — at the same time a proposal to designate North Pacific humpbacks as a single «distinct population segment» is being considered under the Endangered Species Act. Results of the study are being published this week in […]

Living desert underground: In perpetual darkness of limestone cave, surprisingly diverse ecosystem of microbes

Living desert underground: In perpetual darkness of limestone cave, surprisingly diverse ecosystem of microbes

Hidden underneath the hilly grasslands studded with ocotillos and mesquite trees in southeastern Arizona lies a world shrouded in perpetual darkness: Kartchner Caverns, a limestone cave system renowned for its untouched cave formations, sculpted over millennia by groundwater dissolving the bedrock and carving out underground rooms, and passages that attract tourists from all over the […]

Ученые разработали новый катализатор для очистки питьевой воды от нитритов

Ученые разработали новый катализатор для очистки питьевой воды от нитритов

Инженеры-химики из Университета Райса сотворили новый катализатор, который способен быстро разрушать нитриты, общеизвестные вредные примеси в питьевой воде, появляющиеся в результате чрезмерного применения удобрений в сельском хозяйстве. Нитриты и нитраты представляют собой неорганические соединения, которые довольно часто встречаются как в грунтовых, так и в поверхностных водах. Высокое содержание этих соединений опасно для здоровья, поэтому службы […]

Preventing, remediating degradation of soils in Europe through land care

Preventing, remediating degradation of soils in Europe through land care

The European Commission recently granted Wageningen University and partners a 11 million euro international research project focusing on preventing and remediating soil degradation in Europe. The RECARE project is a joint initiative of 27 institutions and organizations in Europe. Wageningen University is lead contractor, with a.o. Alterra and ISRIC as partners. The cross-cutting aim of […]

Catastrophic collapse of Sahara Desert’s wildlife

Catastrophic collapse of Sahara Desert’s wildlife

A new study led by the Wildlife Conservation Society and Zoological Society or London warns that the world’s largest tropical desert, the Sahara, has suffered a catastrophic collapse of its wildlife populations. The study by more than 40 authors representing 28 scientific organizations assessed 14 desert species and found that a shocking half of those […]

Harlequin ladybugs escape enemies while native species succumb

Harlequin ladybugs escape enemies while native species succumb

The astonishing success of the alien invasive harlequin ladybird in Britain has given a team of scientists a unique opportunity to investigate a key ecological theory — the Enemy Release Hypothesis. The Enemy Release Hypothesis predicts that when a new alien species arrives into a country or region it is unlikely that the resident natural […]

Researchers revise Darwin’s thinking on invasive species

Researchers revise Darwin’s thinking on invasive species

For more than a century and a half, researchers interested in invasive species have looked to Charles Darwin and what has come to be called his «naturalization conundrum.» If an invader is closely related to species in a new area, he wrote in his landmark The Origin of Species, it should find a more welcoming […]
