Reef fish arrived in two waves, before and after mass extinction 66 million years ago

Reef fish arrived in two waves, before and after mass extinction 66 million years ago

The world’s reefs are hotbeds of biological diversity, including over 4,500 species of fish. A new study shows that the ancestors of these fish colonized reefs in two distinct waves, before and after the mass extinction event about 66 million years ago that wiped out the dinosaurs. Researchers traced reef fish ancestry by developing a […]

Putting a price on ecological restoration

Putting a price on ecological restoration

Putting a price on clean water and soil fertility helps the UN set ecological restoration targets for degraded and deforested land. Forests provide essential ecosystem services for people, including timber, food and water. For those struggling with the after-effects of deforestation, the main hope lies in rebuilding forest resources through ecological restoration. Forests provide essential […]

Arid areas absorb unexpected amounts of atmospheric carbon

Arid areas absorb unexpected amounts of atmospheric carbon

Researchers have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth’s carbon budget — how much carbon remains in the atmosphere as CO2, contributing to global […]

Ученые из Перу разработали новые билборды, которые ежедневно очищают 100000 кубометров воздуха

Ученые из Перу разработали новые билборды, которые ежедневно очищают 100000 кубометров воздуха

В прошлом году ученые из инженерно-технологического университета Перу (UTEC) выступили с идеей преобразования нормальных рекламных щитов в специальные конструкции, которые будут содействовать решению экологических проблем. Первый рекламный щит, изготовленный учеными и поставленный в Лиме, столице Перу, собирает питьевую воду из влаги, содержащейся в воздухе. А недавно они построили новый щит, который способен очищать до 100000 […]

Oyster aquaculture could significantly improve Potomac River estuary water quality

Oyster aquaculture could significantly improve Potomac River estuary water quality

Oyster aquaculture in the Potomac River estuary could result in significant improvements to water quality, according to a new study. All of the nitrogen currently polluting the Potomac River estuary could be removed if 40 percent of its river bed were used for shellfish cultivation, according to the joint study. The researchers determined that a […]

Water users can reduce risk of spreading invasive species

Water users can reduce risk of spreading invasive species

  Foreign species that are devastating water ecosystems could be ‘hitchhiking’ around Britain on canoeists’ and anglers’ kit, according to a new study. Invaders like the killer shrimp, zebra mussel and American signal crayfish have already caused extensive environmental damage and millions of pounds of economic costs. Invaders like the killer shrimp, zebra mussel and […]

Бурение нефтяных скважин может стать «пусковым механизмом» для сильных землетрясений в Италии

Бурение нефтяных скважин может стать «пусковым механизмом» для сильных землетрясений в Италии

На днях в итальянском регионе Эмилия-Романья было приостановлено бурение новых скважин, после того, как был опубликован доклад, в котором высказано предположение, что разработка и эксплуатация нефтегазоносных слоев воздействовали как «спусковой крючок» для двух сильных землетрясений в 2012 году. В докладе говорится, что деятельность на месторождениях Мирандола, возможно, способствовала усилению сейсмической активности в регионе Эмилия, хотя […]

Moderate resource use, reduced economic inequality keys to sustainability

Moderate resource use, reduced economic inequality keys to sustainability

A new analytical tool adds human factors to a widely-used biological model of how animal populations interact, suggesting that human societies can reach a steady state that is sustainable when they do not over-deplete natural resources and avoid extreme economic inequality. However, the model shows that «if we continue to over-deplete nature, and if inequality […]
