Younger, smaller trees that comprise much of North America’s eastern forests have increased their seed production under climate change, but older, larger trees that dominate forests in much of the West have been less responsive, a new Duke University-led study finds.
The tree species in the Dipterocarpaceae family dominate many tropical forest formations in Southeast Asia (see Figure 1). The Philippines is home to more than 50 dipterocarp tree species, of which 25 cannot be found anywhere else on Earth. About 97% of the Philippines’ tropical forest have been subjected to logging activities, and are often converted to other land uses such as for agriculture. Hence, many of these important and unique tree species are under severe threat. Apart from this, climate change may further threaten the survival of these tree species as environmental conditions become increasingly inhospitable, driving potential shifts in their population ranges.
Werewolf: The Apocalypse – Heart of the Forest is a visual novel with a surprising amount of choice and role-playing elements, based on the well-known tabletop RPG title Werewolf: The Apocalypse. I went into the video game with very little knowledge of the lore that shaped it, and I was honestly surprised how much I… Read More »
Primeval forests are of great importance for biodiversity and global carbon and water cycling. The three-dimensional structure of forests plays an important role here because it influences processes of gas and energy exchange with the atmosphere, whilst also providing habitats for numerous species. An international research team led by the University of Göttingen has investigated the variety of different complex structures that can be found in the world’s forests, as well as the factors that explain this diversity. The results have been published in Nature Communications.
As climate change brings an increase in the frequency and severity of droughts, forest dieback is a key cause for concern: forests act as reservoirs of biodiversity and also allow vast amounts of carbon to be stored, reducing the so-called greenhouse effect. Oak trees, iconic veterans of European and American forests, have previously been thought to be highly vulnerable to drought. Now, thanks to a novel non-invasive optical technique, scientists from INRAE and the University of Bordeaux in France, with their colleagues from University of California, Berkeley and Stanford University have studied a range of oak species in North America to find out more about their resistance to drought. The results, published on 1st March in PNAS, show an evolutionary increase in the drought resistance of oak species which has enabled them to colonize more arid climatic zones and to develop what are, for now, relatively comfortable safety margins to cope with climate change.
