New insect genus discovered in one of the most biodiverse rain forest regions in the world      (via sciencedaily.com)     Original source 

The Allpahuayo-Mishana National Reserve in Peru has often been described as the most biodiverse rainforest in the world. For example, in recent decades, scientist have discovered several new bird species from the region. Researchers from the University of Turku in Finland have studied the insect biodiversity in Allpahuayo-Mishana for over 20 years. In their latest study, the scientist described a new wasp genus, Capitojoppa, to science.

Scientists reveal what fuels wildfires in Sierra Nevada Mountains      (via sciencedaily.com)     Original source 

Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there's a growing need to know exactly what fuels the blazes after they ignite. Scientists now report that one of the chief fuels of wildfires in California's Sierra Nevada mountains is the decades-old remains of large trees.

How weather patterns will change in the future      (via sciencedaily.com)     Original source 

In a warming Pacific Northwest, summers are getting hotter and winters less cold, but the atmospheric patterns that influence the weather aren't necessarily expected to become stronger or more frequent by the end of the century, according to a new study.

New study definitively confirms Gulf Stream weakening, understanding the changes could help predict future trends in extreme events      (via sciencedaily.com)     Original source 

The Gulf Stream transport of water through the Florida Strait has slowed by 4% over the past four decades, with a 99% certainty that this weakening is more than expected from random chance, according to a new study.

How climate warming could disrupt a deep-rooted relationship      (via sciencedaily.com) 

Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.

Long-lasting La Nina events more common over past century      (via sciencedaily.com)     Original source 

Multiyear La Niña events have become more common over the last 100 years, according to a new study. Five out of six La Nina events since 1998 have lasted more than one year, including an unprecedented triple-year event.

Riddle of varying warm water inflow in the Arctic now solved      (via sciencedaily.com)     Original source 

In the 'weather kitchen,' the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time. Experts finally have an explanation for why: Due to unusual atmospheric pressure conditions over the North Atlantic, low-pressure areas are diverted from their usual track, which disrupts the coupling between the Azores High, the Icelandic Low and the winds off the Norwegian coast. This finding is an important step toward refining climate models and more accurately predicting the fate of Arctic sea ice in the face of progressing climate change.

Plant and forest researchers do not 'anthropomorphize' plants      (via sciencedaily.com)     Original source 

Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.

New research brings greater understanding of Asian winter monsoon      (via sciencedaily.com)     Original source 

Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.

Canopy gaps help eastern hemlock outlast invasive insect      (via sciencedaily.com)     Original source 

Creating physical gaps in the forest canopy give eastern hemlocks more access to resources and help those trees withstand infestation by an invasive insect.

Almost half of koala habitats will be under high bushfire threat by 2070      (via sciencedaily.com) 

The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.

Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration      (via sciencedaily.com) 

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.

Largest historic fire death toll belongs to aftermath of 1923 Japan Earthquake      (via sciencedaily.com)     Original source 

Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kant earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history -- comparable to the number of people killed in the World War II atomic bombing of Hiroshima. The story of the conflagration, not well-known outside of Japan, holds important lessons for earthquake scientists, emergency response teams and city planners, according to a new article.
