Climate change, predators, and trickle down effects on ecosystems

Climate change, predators, and trickle down effects on ecosystems

Predators play important roles in maintaining diverse and stable ecosystems. Climate change can push species to move in order to stay in their climatic comfort zones, potentially altering where species live and how they interact, which could fundamentally transform current ecosystems. A symposium focusing on climate’s effects on predators — causing cascading effects on whole [...]

Study measures steep coastal costs of China’s GDP growth

Economic activity, as in this floating mariculture installation at Sanya, is having a dramatic effect on the health of China’s seas. Credit: Ying Chen     A new study by a team of Chinese and American conservation biologists quantifies the serious consequences of China’s recent economic growth on its coastal ecosystems. By several measures, 1978 [...]

Датчики с бактериями будут использоваться для обнаружения загрязнения питьевой воды

Датчики с бактериями будут использоваться для обнаружения загрязнения питьевой воды

Ученые из американского Департамента химического инжиниринга и Бристольской лаборатории робототехники на днях огласили о разработке недорогого прибора, который можно было бы применить в развивающихся странах для контроля качества питьевой воды в режиме реального времени без дорогостоящего лабораторного оборудования. Современные методы обнаружения загрязнителей в воде довольно дорогостоящие, трудоемкие и требуют особых технических знаний. Новый датчик, который [...]

Climate warming may have unexpected impact on invasive species, study finds

Climate warming may have unexpected impact on invasive species, study finds

Rising temperatures may be seen as universally beneficial for non-native species expanding northward, but a Dartmouth College study suggests a warmer world may help some invaders but hurt others depending on how they and native enemies and competitors respond. The study, which sheds light on the uncertain relationship between climate change and invasive species, appears [...]

В воде, орошаемой китайские парки, найдены супербактерии, устойчивые к антибиотикам

В воде, орошаемой китайские парки, найдены супербактерии, устойчивые к антибиотикам

На днях исследователи из Китайской академии наук в Пекине сделали тревожное открытие: во время инспектирования общественных парков в семи городах Китая они обнаружили, что в системах орошения парков переработанными сточными водами количество генов с антибактериальной резистентностью (ARG) в 8655 раз выше, чем в системах орошения с пресной водой. Стоит отметить, что измеренное численность генов, устойчивых [...]
