Published Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken
(via sciencedaily.com) Original source Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.
Published A database unifies the information on damage to European forests over the last 60 years
(via sciencedaily.com) Original source Researchers are creating a database that harmonizes the recording of disturbances caused by insects and diseases in forests in 8 European countries by combining remote sensing, satellite images and field data.
Published The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal
(via sciencedaily.com) Original source Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.
Published Large herbivores such as elephants, bison and moose contribute to tree diversity
(via sciencedaily.com) Original source Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests
(via sciencedaily.com) Original source Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published Even treated wood prevents bacterial transmission by hand
(via sciencedaily.com) Original source According to a new study, surface treatment and moisture affect the antibacterial properties of wood. Based on the findings, treated wood should be increasingly used as surface material.
Published New study finds hidden trees across Europe: A billion tons of biomass is overlooked today
(via sciencedaily.com) Original source Through satellite imaging a new AI driven mapping of biomass and CO2 storage shows that a huge number of trees are overlooked in Europe's urban, rural, and agricultural areas. Across Europe, researchers have discovered a billion tons of hidden biomass.
Published New study shows surprising effects of fire in North America's boreal forests
(via sciencedaily.com) Original source Using satellite images, researchers found that fires in North America's boreal forest may be changing the environment in ways that researchers didn't previously anticipate.
Published Unearthing the ecological impacts of cicada emergences on North American forests
(via sciencedaily.com) Original source New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Yeast speeds discovery of medicinal compounds in plants
(via sciencedaily.com) Original source Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Study elucidates evolution of mosquitoes and their hosts
(via sciencedaily.com) Original source Study creates a mosquito family tree to better understand disease transmission and host choice.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought
(via sciencedaily.com) Original source For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
Published Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say
(via sciencedaily.com) Original source The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.
Published Timing plant evolution with a fast-ticking epigenetic clock
(via sciencedaily.com) Original source Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.
Published New research reveals dynamic factors shaping biodiversity at small scales
(via sciencedaily.com) Original source Researchers studying arboreal ants in a Florida forest explore the fundamental question of how resource availability and competition shape biodiversity.
Published 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.
Published 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.
Published 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.
Published 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.
