Researchers studying arboreal ants in a Florida forest explore the fundamental question of how resource availability and competition shape biodiversity.View the full article

Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.View the full article

How are environmental changes, loss of biodiversity, and the spread of pathogens connected? The answer is a puzzle. Researchers have now described one piece of that puzzle, showing that the destruction of tropical rainforests harms the diversity of mosquito species. At the same time, more resilient species of mosquitoes become more prevalent -- which also means the viruses they carry are more abundant. If there are many individuals of a given species, those viruses can spread quickly.View the full article

For the first time, researchers have extracted ancient DNA from Caribbean parrot fossils and archaeological specimens, showing that species thought to be endemic to particular islands were historically more widespread and diverse.View the full article

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.View the full article

Scientists have mapped the reproductive strategies and life cycle of an endangered coral species, the purple cauliflower soft coral Dendronephthya australis. Lab-grown larvae have been successfully introduced back into the wild.View the full article

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.View the full article

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.View the full article

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

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.View the full article

• 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.View the full article

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.View the full article

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.View the full article

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.View the full article

A new report presents major findings on the gravity of impacts from invasive alien species on our planet.View the full article

Invasive alien species are animals that may pose a threat to biodiversity, but it's time to deal with that threat in a more ethical way.View the full article

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.View the full article

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.View the full article

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.View the full article

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.View the full article

New work could help forest managers predict which forests are most at risk from drought and which will survive.View the full article

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.View the full article
