Published Wildfires and animal biodiversity
(via sciencedaily.com)
Original source 
Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.
Published Professor unearths the ancient fossil plant history of Burnaby Mountain
(via sciencedaily.com)
Original source 
New research led by a paleobotanist provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer than it is today.
Published Engineers devise technology to prevent fouling in photobioreactors for CO2 capture
(via sciencedaily.com)
Original source 
A new, inexpensive technology can limit the buildup of algae on the walls of photobioreactors that can help convert carbon dioxide into useful products. Reducing this fouling avoids costly cleanouts and allows more photosynthesis to happen within tanks.
Published Predictive power of climate models may be masked by volcanoes
(via sciencedaily.com)
Original source 
Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study.
Published Oldest bat skeletons ever found described from Wyoming fossils
(via sciencedaily.com)
Original source 
Scientists have described a new species of bat based on the oldest bat skeletons ever recovered. The study on the extinct bat, which lived in Wyoming about 52 million years ago, supports the idea that bats diversified rapidly on multiple continents during this time.
Published Timing of snowshoe hare winter color swap may leave them exposed in changing climate, study finds
(via sciencedaily.com)
Original source 
A new study, which used 44 years of data, shows that as the globe has warmed, altering the timing and amount of snow cover, snowshoe hares' winter transformation may be out of sync with the color of the background environment; this may actually put them at a greater disadvantage.
Published The hidden culprit behind nitrogen dioxide emissions
(via sciencedaily.com)
Original source 
A research team assesses neighborhood-scale NO2 exposure using a European satellite. High-rise apartment complexes are a significant source of emissions that should be considered in the development of clean air policies.
Published Multifunctional patch offers early detection of plant diseases, other crop threats
(via sciencedaily.com)
Original source 
Researchers have developed an electronic patch that can be applied to the leaves of plants to monitor crops for different pathogens -- such as viral and fungal infections -- and stresses such as drought or salinity. In testing, the researchers found the patch was able to detect a viral infection in tomatoes more than a week before growers would be able to detect any visible symptoms of disease.
Published Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists
(via sciencedaily.com)
Original source 
Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.
Published Humans need Earth-like ecosystem for deep-space living
(via sciencedaily.com)
Original source 
Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.
Published British flower study reveals surprise about plants' sex life
(via sciencedaily.com)
Original source 
A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces. When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.
Published Critical observations of sinking coasts
(via sciencedaily.com)
Original source 
Using satellite-obtained data from 2007-21, researchers mapped the entire East Coast to demonstrate how the inclusion of land subsidence reveals many areas to be more vulnerable to floods and erosion than previously thought.
Published Study predicts poor survival rates if Ebola infects endangered mountain gorillas
(via sciencedaily.com)
Original source 
If infected with the Ebola virus, less than 20 percent of Africa's endangered mountain gorillas would be expected to survive more than 100 days, finds a new study.
Published As rising temperatures affect Alaskan rivers, effects ripple through Indigenous communities
(via sciencedaily.com)
Original source 
Six decades of river gage data gathered from nine rivers in Alaska highlight the cumulative and consequential impacts of climate change for local communities and ecosystems in the Arctic.
Published How an African bird might inspire a better water bottle
(via sciencedaily.com)
Original source 
An extreme closeup of feathers from a bird with an uncanny ability to hold water while it flies could inspire the next generation of absorbent materials.
Published Electrification push will have enormous impacts on critical metals supply chain
(via sciencedaily.com)
Original source 
The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.
Published Stopping storms from creating dangerous urban geysers
(via sciencedaily.com)
Original source 
Researchers develop a computational model of stormwater piping to study storm geysers. They used this model to understand why storm geysers form, what conditions tend to make them worse, and what city planners can do to prevent them from occurring. The authors say the best cure for a storm geyser is bigger pipes; however, that advice is little help to cities with existing pipeline infrastructure. In these systems, the focus must be on minimizing the potential damage by reducing the height of the geysers, the volume of expelled water, or the resulting damage to the pipeline.
Published Lightning strike creates phosphorus material
(via sciencedaily.com)
Original source 
A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.
Published Trees in areas prone to hurricanes have strong ability to survive even after severe damage
(via sciencedaily.com)
Original source 
The island of Dominica took a direct hit from Category 5 Hurricane Maria. Nine months afterward, researchers found that while 89% percent of trees located in nine previously documented forest stands were damaged, but only 10 percent had immediately died. The most common damage was stem snapping and major branch damage. The damage with the highest rates of mortality were uprooting and being crushed by a neighboring tree. Large individual trees and species with lower wood density were susceptible to snapping, uprooting and mortality. Those on steeper slopes were more prone to being crushed by neighboring trees.
Published Temperature is stronger than light and flow as driver of oxygen in US rivers
(via sciencedaily.com)
Original source 
The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow. To better understand which factor has the greatest impact on the concentration of dissolved oxygen, researchers used a deep learning model to analyze data from hundreds of rivers across the United States.
