New research finds that ash dieback is far less severe in the isolated conditions ash is often found in, such as forests with low ash density or in open canopies like hedges, suggesting the long term impact of the disease on Europe’s ash trees will be more limited than previously thought.
Over the course of forest succession, both components of plant residues and the structure of soil microbial communities play important roles in affecting soil aggregates, and thus the sequestration and stability of soil organic carbon. However, up till now there is still a lack of holistic understanding of the interactions among root turnover, microbial community composition, chemical composition of plant residues and different sized soil aggregates.
Tropical forest trees are the centerpiece of debates on conservation, climate change and carbon sequestration today. While their ecological importance has never been doubted, what has often been ignored is their ability to store cultural heritage. Using recent advances in scientific methods and a better understanding of the growth of these trees, researchers can now uncover, in detail, the growing conditions, including human management, that have occurred around these ancient giants over their centuries-long life span.
Collectively organising agricultural nature management leads to increased levels of trust between those involved, as well as to a more confidence in the policy.
Field trials show that poplar trees can be genetically modified to reduce negative impacts on air quality while leaving their growth potential virtually unchanged
The synchronization of seed production by trees has garnered attention due to its importance in agriculture, forestry and ecosystem management. Therefore, understanding the timing and mechanisms that contribute to synchronized seeding can be a useful management tool.
A new study shows that lodgepole pine trees with larger resin ducts survived beetle attacks that killed trees with smaller ducts. Located in the needles, branches, trunk and roots, the ducts act like highways to carry sticky, toxic resin to whatever part of the tree is being attacked.
Botanists from have discovered that “penny-pinching” evergreen species such as Christmas favourites, holly and ivy, are more climate change-ready in the face of warming temperatures than deciduous “big-spending” water consumers like birch and oak. As such, they are more likely to prosper in the near future.
Oaks have a complex evolutionary history that has long eluded scientists. New research, however, provides the most detailed account to date of the evolution of oaks, recovering the 56-million-year history that has made the oaks one of the most diverse, abundant and important woody plant groups to the ecology and economy of the northern hemisphere.
A new study reveals a complex interplay between soil fungi and tree roots that could be the cause of rare-species advantage. The researchers found that the type of beneficial soil fungi living around tree roots in a subtropical forest in China determined how quickly the trees accumulated harmful, pathogenic fungi as they grew. The rate of accumulation of pathogenic fungi strongly influenced how well the trees survived when growing near trees of the same species.
