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.

Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction      (via sciencedaily.com)     Original source 

A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.

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.

Pollination by more than one bee species improves cherry harvest      (via sciencedaily.com)     Original source 

To obtain the biggest cherry harvest, trees should be pollinated by both honey bees and mason bees. This new study shows yet another benefit of biodiversity.

Freshwater connectivity can transport environmental DNA through the landscape      (via sciencedaily.com) 

A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.

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.

Invasive red fire ants spreading in Europe      (via sciencedaily.com)     Original source 

One of the most invasive species in the world is Solenopsis invicta, a red fire ant species with a painful sting. Native to South America, the ant has established itself across the globe. A group of ant experts confirm that the species has made its way to Sicily -- the ant's first official sighting in Europe. The ants could soon spread all over the continent, the researchers warn, which could cause major environmental, health, and economic problems in Italy and beyond.

New research highlights opportunities to protect carbon and communities from forest fires      (via sciencedaily.com)     Original source 

As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.

Large herbivores keep invasive plants at bay      (via sciencedaily.com) 

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.

Extreme El Niño weather saw South America's forest carbon sink switch off      (via sciencedaily.com)     Original source 

Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.

Invasive spotted lanternfly may not damage hardwood trees as previously thought      (via sciencedaily.com)     Original source 

In 2012, when the spotted lanternfly (Lycorma delicatula) arrived in the U.S. from its home in China, scientists, land managers, and growers were understandably concerned that the sap-feeding insect would damage native and commercial trees. New long-term research has discovered that hardwood trees, such as maple, willow and birch, may be less vulnerable than initially thought.

Evolutionary imbalance explains global plant invasions      (via sciencedaily.com)     Original source 

Plant species from certain geographic regions are more successful in spreading outside their native ranges than others -- but why? Ecologists provide answers by exploring how the ecological and evolutionary histories of plants can influence their relationships with humans and their success as invaders.

Want to fight climate change? Don't poach gorillas (or elephants, hornbills, toucans, etc.)      (via sciencedaily.com)     Original source 

A new article found that overhunting of gorillas, elephants, and other large fruit-eating seed-dispersers make tropical forests less able to store or sequester carbon.

Wildfire, soil emissions increasing air pollution in remote forests      (via sciencedaily.com)     Original source 

Nitrogen dioxide levels in remote forest areas are increasing, and wildfire and soil emissions are likely the reasons why, finds a new study.
