MethaneMapper is poised to solve the problem of underreported methane emissions      (via sciencedaily.com)     Original source 

MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.

Lost giants: New study reveals the abundance decline of African megafauna      (via sciencedaily.com)     Original source 

A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.

Older trees accumulate more mutations than their younger counterparts      (via sciencedaily.com)     Original source 

A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.

Whales not to be counted on as 'climate savers'      (via sciencedaily.com)     Original source 

Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.

River diversions may cause microplastics to remain longer on land and in streams before reaching oceans      (via sciencedaily.com)     Original source 

Diverting streams and rivers to irrigate crops or provide drinking water may significantly extend the time microplastics spend in river catchments before they flow into our oceans, a new study reveals.

Lessons from 'The Blob' will help us manage fisheries during future marine heatwaves      (via sciencedaily.com)     Original source 

In early 2014, a great anomaly descended upon the seas: A patch of warm water that manifested in the Gulf of Alaska. Scientists called it 'The Blob.'

Ancient viruses discovered in coral symbionts' DNA      (via sciencedaily.com)     Original source 

The symbiotic organisms that live in corals and provide them with their dramatic colors contain fragments of ancient RNA viruses that are as much as 160 million years old.

Little-known microbes could help predict climate tipping points      (via sciencedaily.com)     Original source 

Rising temperatures could push ocean plankton and other single-celled creatures toward a carbon tipping point that fuels more warming. The carbon-eaters could become carbon-emitters. But new research shows it's also possible to detect early distress signals before they get there.

Ticks prove resilient to extreme temperatures      (via sciencedaily.com)     Original source 

A recent study shows blacklegged ticks (Ixodes scapularis) are actually really good at surviving extreme cold and heat in nature. Previous lab research suggests that even short periods of especially warm or cold conditions should easily kill ticks, but the a new analysis reveals this is only the case for larval ticks in the environment.

Forest protection and carbon dioxide stored in biomass      (via sciencedaily.com)     Original source 

A study has found that worldwide protected forests have an additional 9.65 billion metric tons of carbon stored in their above-ground biomass compared to ecologically similar unprotected areas.

Forest birds with short, round wings more sensitive to habitat fragmentation      (via sciencedaily.com)     Original source 

Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.

Thermal energy stored by land masses has increased significantly      (via sciencedaily.com)     Original source 

There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.

Desert ant increase the visibility of their nest entrances in the absence of landmarks      (via sciencedaily.com)     Original source 

Researchers report that in the absence of visible landmarks, desert ants increase the likelihood that foraging nest mates will find their way home quickly and safely by elevating their nest entrance. Ant colonies whose nests are found deep in the Tunisian saltpan are particularly reliant on the self-made landmarks. If the mound at the nest entrance was removed, they immediately began building a new hill, unless the researchers provided artificial landmarks. This phenomenon adds yet another fascinating facet to the amazing navigation skills of these tiny desert animals.

Protecting large ocean areas doesn't curb fishing catches      (via sciencedaily.com)     Original source 

In the first-ever 'before and after' assessment of the impact of establishing Mexico's Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico's industrial fishing sector did not incur economic losses five years after the park's creation despite a full ban in fishing activity within the MPA.

Mitigating climate change through restoration of coastal ecosystems      (via sciencedaily.com)     Original source 

Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.
