«Нано-очистители» следующего поколения будут очищать воду быстрее и эффективнее

  Согласно оценкам, приведенным в последнем совместном докладе ВОЗ и ЮНИСЕФ, 768 миллионов людей используют непроверенными источниками питьевой воды, и 185 миллионов из них применяют для питья и приготовления пищи поверхностные воды суши. В связи с этим ВОЗ и ЮНИСЕФ поставили перед собой задачу к 2030 году обеспечить каждому человеку на Земле доступ к безопасной […]

In the Northeast, forests with entirely native flora are not the norm

In the Northeast, forests with entirely native flora are not the norm

Two-thirds of all forest inventory plots in the Northeast and Midwestern United States contain at least one non-native plant species, a new U.S. Forest Service study found. The study across two dozen states from North Dakota to Maine can help land managers pinpoint areas on the landscape where invasive plants might take root. » We […]

Cheating favors extinction, yeast study finds: Feedback between population and evolutionary dynamics

Cheating favors extinction, yeast study finds: Feedback between population and evolutionary dynamics

Cooperative behaviour is widely observed in nature, but there remains the possibility that so-called ‘cheaters’ can exploit the system, taking without giving, with uncertain consequences for the social unit as a whole. A new study has found that a yeast colony dominated by non-producers (‘cheaters’) is more likely to face extinction than one consisting entirely […]

Amphibians living close to farm fields are more resistant to common insecticides

Amphibians living close to farm fields are more resistant to common insecticides

Amphibian populations living close to agricultural fields have become more resistant to a common insecticide and are actually resistant to multiple common insecticides, according to two recent studies conducted at the University of Pittsburgh.Amphibian populations living close to agricultural fields have become more resistant to a common insecticide and are actually resistant to multiple common […]

Smoke signals: How burning plants tell seeds to rise from the ashes

Smoke signals: How burning plants tell seeds to rise from the ashes

In the spring following a forest fire, trees that survived the blaze explode in new growth and plants sprout in abundance from the scorched earth. For centuries, it was a mystery how seeds, some long dormant in the soil, knew to push through the ashes to regenerate the burned forest. In the April 23 early […]

Biologists propose a new research roadmap for connecting genes to ecology

Biologists propose a new research roadmap for connecting genes to ecology

A team of researchers at the University of Massachusetts Amherst is proposing a new investigative roadmap for the field of evolutionary developmental biology, or «evo devo,» to better understand how innovation at the genetic level can lead to ecological adaptations over time. Evo devo seeks to understand the specific genetic mechanisms underlying evolutionary change. Seven […]

World’s longest-running plant monitoring program now digitized

World’s longest-running plant monitoring program now digitized

Researchers at the University of Arizona’s Tumamoc Hill have digitized 106 years of growth data on individual plants, making the information available for study by people all over the world. Knowing how plants respond to changing conditions over many decades provides new insights into how ecosystems behave. The permanent research plots on Tumamoc Hill represent […]

Ecological knowledge offers perspectives for sustainable agriculture

Ecological knowledge offers perspectives for sustainable agriculture

A smart combination of different crops, such as beans and maize, can significantly cut the use of crop protection agents and at the same time reduce the need for fertilizers. Integrating ecological knowledge from nature with knowledge of crops opens up the prospect of a sustainable strategy that will increase yield per hectare at reduced […]

Actiuni menite sa atraga atentia soferilor asupra existentei biciclistilor in trafic

Actiuni menite sa atraga atentia soferilor asupra existentei biciclistilor in trafic

De la 1 iunie, politistii au anuntat o serie de actiuni menite sa atraga atentia soferilor asupra existentei biciclistilor in trafic, in conditiile inmultirii accidentelor in care acestia din urma sunt victime. Unul din cititorii Turnul Sfatului a transmis redactiei o serie de fotografii prin care ilustreaza una din primele probleme ale celor care folosesc […]

Rare species perform unique roles, even in diverse ecosystems

Rare species perform unique roles, even in diverse ecosystems

A new study, published 28 May in the open access journal PLOS Biology, has revealed the potential importance of rare species in the functioning of highly diverse ecosystems. Using data from three very different ecosystems — coral reefs, tropical forests and alpine meadows — a team of researchers led by David Mouillot at the University […]
