Open any history book and you’re likely to find that the practice of agriculture was invented 12,000 years ago in the Levant, an area in the Middle East that was home to some of the first human civilizations. But a new discovery recently made in Northern Israel seems to have shattered the myth on the advent of agriculture, offering up exciting evidence that trial plant cultivation, what we call agriculture, began far earlier – some 23,000-years-ago.
In a momentous decision, the California Fish & Game Commission has voted to ban the trapping of bobcats.
Assembly Bill 1213, prohibiting the trapping and killing of bobcats statewide, passed the California legislature in 2013, but for the past two years it has not been fully implemented.
A Care2 petition demanding that California legislators and the Fish and Game Commission be more diligent in protecting the bobcat by fully enforcing the Bobcat Protection Act has garnered over 77,000 signatures. In a huge victory for Care2 members, the members of the Commission voted to implement a total ban on bobcat trapping.
As temperatures rise, some of the organic carbon stored in Arctic permafrost meets an unexpected fate—burial at sea. As many as 2.2 million metric tons of organic carbon per year are swept along by a single river system into Arctic Ocean sediment, according to a new study an international team of researchers published today in Nature. This process locks away carbon dioxide (CO2) - a greenhouse gas - and helps stabilize the earth’s CO2 levels over time, and it may help scientists better predict how the natural carbon cycle will interplay with the surge of CO2 emissions due to human activities.
“The erosion of permafrost carbon is very significant,” says Woods Hole Oceanographic Institution (WHOI) Associate Scientist Valier Galy, a co-author of the study. “Over thousands of years, this process is locking CO2away from the atmosphere in a way that amounts to fairly large carbon stocks. If we can understand how this process works, we can predict how it will respond as the climate changes.”
Insecticides that are sprayed in orchards and fields across North America may be more toxic to spiders than scientists previously believed. A McGill research team reached this conclusion after looking at changes in the behaviour of individual Bronze Jumping Spiders both before and after exposure to Phosmet, a widely used broad spectrum insecticide. It is a finding with far-reaching implications for agricultural production and ecosystem health.
África tiene la mitad de los leones que tenía hace 20 años, pero no culpe a los trofeos de caza. El asesinato del León Cecil de Zimbabwe, ha puesto los reflectores sobre la alarmante disminución de los leones en África, escriben Lochran Traill y Norman Owen-Smith. Pero para salvar a la especie, no hay que obsesionarse con la obtención de trofeos, sino con problemas mucho más graves, como la falta de desarrollo y la fragmentación del hábitat.
Horses share some surprisingly similar facial expressions to humans and chimps, according to new University of Sussex research. Mammal communication researchers have shown that, like humans, horses use muscles underlying various facial features - including their nostrils, lips and eyes - to alter their facial expressions in a variety of social situations.
