| Posted: 01 Nov 2021 04:08 PM PDT A new study that modeled changes in the world's 45 different 'life zones' from climate change revealed that climate impacts may soon triple over these areas if the earth continues 'business-as-usual' emissions. |
| The silent build-up to a super-eruption Posted: 01 Nov 2021 12:48 PM PDT It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last one million years. But when will the next one be? Will there be any warning signs? To answer these questions, an international team of geologists developed an analysis of the levels of uranium and lead in zircons -- a mineral typically found in explosive volcanic eruptions -- to determine how long it took the volcano to prepare for its super-eruptions. |
| Study shows how 1.5°C temperature rise can cause significant changes in coastal species Posted: 01 Nov 2021 11:17 AM PDT As COP26 leaders gather in the UK, new research shows a temperature increase of around 1.5°C -- just under the maximum target agreed at the COP23 Paris meeting in 2017 -- can have a marked impact on algae and animal species living on our coastlines. |
| Posted: 01 Nov 2021 11:17 AM PDT The mid-ocean 'twilight zone' holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult. Many inhabitants of the twilight zone are easily destroyed during sampling -- or are quick to avoid any disturbance -- so it's difficult to sample them with traditional nets. Advances in acoustics have enabled more accurate estimates of biomass, but questions about the diversity and distribution of species within that biomass remain unanswered. |
| How bread wheat got its gluten: Tracing the impact of a long-lost relative on modern bread wheat Posted: 01 Nov 2021 11:17 AM PDT Genetic detective work has uncovered an obscure ancestor of modern bread wheat, in a finding similar to uncovering a famous long-lost relative through DNA analysis in humans. |
| Uncovering the secrets behind Earth’s first major mass extinction Posted: 01 Nov 2021 11:15 AM PDT New research reveals more information about the first and oldest of the 'big five' extinctions. Around 85% of marine species, most of which lived in shallow oceans near continents, disappeared during that time. |
| Snakes more likely to inbreed and lose ability to adapt due to urbanization Posted: 01 Nov 2021 07:54 AM PDT New research has found that isolated Perth tiger snake populations, such as those surrounded by urban development or seawater, are more likely to resort to inbreeding than those in less 'cut off' communities. |
| A reef in two gears: New patterns of coral recovery discovered Posted: 01 Nov 2021 07:54 AM PDT Combining an innovative approach developed for medical sciences mathematicians and marine ecologists have identified new coral recovery patterns in the Great Barrier Reef, providing critical information for the management of the reef. |
| Ancestors of whale sharks in Panama may come from distant waters Posted: 28 Oct 2021 09:04 AM PDT Genetic population connectivity study of the endangered whale shark in Pacific Panama provides important baseline data for conservation efforts. |
| Clues from the ancient past can help predict abrupt climate change Posted: 25 Oct 2021 02:20 PM PDT Climate 'tipping points' can be better understood and predicted using climate change data taken from the ancient past, new research shows. |
