How species colonize habitats opened by anthropogenic land cover change

Wed, 09/11/2019 - 22:11
As plants expand into new open habitats, geographical and climatic factors may matter more than species-specific traits, according to a new study.

Topography could save sensitive saguaros as climate changes

Wed, 09/11/2019 - 22:11
By studying nearly five decades of data on more than 5,800 saguaros dotting Tumamoc Hill, researchers found that small variations in the hill's topography might buffer saguaro populations from the impacts of climate change.

Digital records of preserved plants and animals change how scientists explore the world

Wed, 09/11/2019 - 21:27
There's a whole world behind the scenes at natural history museums that most people never see -- millions upon millions of dinosaur bones, pickled sharks, dried leaves, and every other part of the natural world. These specimens are used in research by scientists trying to understand how different kinds of life evolved and how we can protect them. A study shows how scientists are using digital records of all these specimens in their research.

The danger of heat and cold across Australia

Wed, 09/11/2019 - 19:19
Cold temperatures are not nearly as deadly as heat, with around 2% of all deaths in Australia related to heat, according to new research.

Aphid-stressed pines show different secondary organic aerosol formation

Wed, 09/11/2019 - 19:19
Plants emit gases, called volatile organic compounds (VOCs), that enter the atmosphere, where they can interact with other natural and human-made molecules to form secondary organic aerosols (SOAs). These tiny, suspended particles influence atmospheric processes, such as cloud formation and sunlight scattering. Now, researchers have shown that aphid-infested Scots pine trees produce a different mixture of VOCs than healthy plants, which then leads to different SOAs.

Conserving rare species for the maintenance of Mediterranean forests

Wed, 09/11/2019 - 18:30
This study has shown the importance of conserving rare species for the maintenance of complex ecosystems like Mediterranean forests. Therefore, for these species, it becomes essential to understand the factors that make conservation successful.

'Planting water' is possible -- against aridity and droughts

Wed, 09/11/2019 - 17:16
Scientists have developed a mathematical model that can reflect the complex interplays between vegetation, soil and water regimes. They show, for example, that in beech forests water is increasingly cycled between soil and vegetation to increase evaporation to the atmosphere, while grass cover promotes groundwater recharge.

How much photovoltaics (PV) would be needed to power the world sustainably?

Wed, 09/11/2019 - 17:15
The International Energy Agency has dubbed increased global cooling demand as one of the most critical blind spots in today's energy debate.

Focusing on key sustainable development goals would boost progress across all, analysis finds

Wed, 09/11/2019 - 14:42
The world could make greater progress towards the United Nations Sustainable Development Goals by prioritizing a subset of the goals rather than pursuing them all equally, a first-of-its-kind mathematical study reveals.

Satellite data record shows climate change's impact on fires

Tue, 09/10/2019 - 22:46
While every fire needs a spark to ignite and fuel to burn, it's the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the world has increasingly warmed, so has its potential to burn.

Microorganisms reduce methane release from the ocean

Tue, 09/10/2019 - 20:43
Bacteria in the Pacific Ocean remove large amounts of the greenhouse gas methane.

New volcanic eruption forecasting technique

Tue, 09/10/2019 - 16:54
Volcanic eruptions and their ash clouds pose a significant hazard to population centers and air travel, especially those that show few to no signs of unrest beforehand. Geologists are now using a technique traditionally used in weather and climate forecasting to develop new eruption forecasting models. By testing if the models are able to capture the likelihood of past eruptions, the researchers are making strides in the science of volcanic forecasting.

Rocks at asteroid impact site record first day of dinosaur extinction

Mon, 09/09/2019 - 23:01
The research centers on the asteroid impact that wiped out non-avian dinosaurs, with the researchers getting the most detailed look yet of the aftermath that followed by examining the rocks and debris that filled the crater within the first 24 hours after impact.

Ages of the Navajo Sandstone

Mon, 09/09/2019 - 20:11
The Navajo Sandstone is known for its beautiful red and tan crossbedded sandstones that grace many of the national parks and monuments in the southwest USA. The sands were deposited in dunes within the largest known sand sea (erg) in Earth's history during the Early Jurassic. These deposits show a record of desertification -- the process by which fertile lands become desert. How did this landscape lose its water bodies, vegetation, and animals?

Researchers unearth 'new' mass-extinction

Mon, 09/09/2019 - 17:55
A team of scientists has concluded that earth experienced a previously underestimated severe mass-extinction event, which occurred about 260 million years ago.

Beyond borders: Understanding migration requires understanding changing land systems

Mon, 09/09/2019 - 17:47
For tens of millions of people, migration is a tough reality. What causes people to migrate away from their home countries, and what happens when they do? Migrants and their labor are responsible for moving hundreds of billions of dollars around the world annually. At their destinations, they affect populations, cultures, and economies. But their movement also has a major impact on the places they leave, including on how people use land.

Warm on top, cold below: Unexpected greenhouse gas effect in lakes

Mon, 09/09/2019 - 17:47
A research team has examined how the ongoing climate warming affects the 'behavior' of lakes. The researchers found out why, in near-bottom waters, lakes may even cool down despite warming at the surface, and what the consequences are for the production and emission of greenhouse gases.

Climate change water variability hurts salamander populations

Sat, 09/07/2019 - 00:24
New research suggests that streamflow variability brought on by climate change will negatively affect the survival of salamanders.

Tracking sulfur-based metabolism in the open ocean

Fri, 09/06/2019 - 16:06
Oceanographers found that marine microbes process sulfonate, a plentiful marine nutrient, in a way that is similar to soils.
