Published Bees struggle to find flowers because of air pollution



A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent.
Published Artificial intelligence could help build pollen jigsaw of present and ancient flora



An emerging system which combines rapid imaging with artificial intelligence could help scientists build a comprehensive picture of present and historic environmental change -- by swiftly and accurately analyzing pollen.
Published Invasive alien species play key role in 60% of global plant and animal extinctions


A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published Echoes of extinctions: Novel method unearths disruptions in mammal trait-environment relationships



New research explores the historical shifts in mammal traits and biodiversity loss in eastern Africa. The study reveals how environmental changes disrupted mammal communities and highlights the urgent need for targeted conservation efforts to protect vulnerable species.
Published Capturing carbon in savannas: New research examines role of grasses for controlling climate change


New research shows that, in addition to trees, humble grasses also play an essential role in capturing carbon.
Published New research highlights opportunities to protect carbon and communities from forest fires



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.
Published How does the social behavior of wheat plants influence grain production?



Researchers have investigated how the behavior of an individual wheat plant under limiting light conditions influences the performance of the whole community. They assessed morphological and biomass phenotypes of single plants grown in mixtures under sunlight and a simulated canopy shade, and the relevance of these phenotypes for the monoculture community in the field.
Published Fossil spines reveal deep sea's past



Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
Published Balancing biodiversity, climate change, food for a trifecta


Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.
Published Invasive species are animals, too: Considering a humane approach


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.
Published Three out of four populations of rare butterflies have been lost



In just 26 years, the distribution of rare butterflies has plummeted by 72% in Eastern Denmark. Several species are threatened with extinction, yet the conservation actions aiming to safeguard species have proved unsuccessful.
Published Pioneering research sheds surprising new light on evolution of plant kingdom



A new study has uncovered intriguing insights into the evolution of plant biology, effectively rewriting the history of how they evolved over the past billion years.
Published Large herbivores keep invasive plants at bay


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.
Published Farms that create habitat key to food security and biodiversity


Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
Published Most species are rare, but not very rare



More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common. These so-called global species abundance distributions have become fully unveiled for some well-monitored species groups, such as birds. For other species groups, such as insects, however, the veil remains partially unlifted. A new study demonstrates how important biodiversity monitoring is for detecting species abundances on planet Earth and for understanding how they change.
Published Extreme El Niño weather saw South America's forest carbon sink switch off



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.
Published Better cybersecurity with new material


Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Flowering for naught: 120 years with nothing to show



Flowering for some plants is a yearly occurrence, for others, it is a once-in-a-lifetime event. A widespread species of bamboo in Japan, Phyllostachys nigra var. henonis, takes this one-time flowering event and pushes it to the extreme: they flower once every 120 years before dying to make way for the next generation. Researchers have realized there might be another issue at hand with this monocarpic species, which is the lack of germination of the seeds from a majority of the flowering specimens. Implications of a once dense field of bamboo, something that serves both as a food source and a source of material for crafts, turning to grassland for several years until the regeneration of bamboo begins to start somehow, can impact the ecology of the area in addition to the country's economy.
Published A global observatory to monitor Earth's biodiversity



At a time of unparalleled rates of biodiversity loss, a new interconnected system to monitor biodiversity around the world is needed to guide action quickly enough to target conservation efforts to where they are most needed.
Published Evolutionary imbalance explains global plant invasions



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.
