So, why are healthy, green leaves from maple trees falling to the ground? This injury, caused by a tiny insect called the “Maple Petiole Borer”, does not cause any serious harm to the tree even though it might appear that the tree has lost a large percentage of its foliage.
Leaf measurements are often critical in plant physiological and ecological studies, but traditional methods have been time consuming and sometimes destructive to plant samples.
Trees species range in size from the Dwarf Willow at 2.5 inches to the coastal Redwood which averages 50 feet, but can top out at over 300 feet. As the coastal Redwood shows, even within one tree species, there can be a wide range of sizes. What limits the height, even within a single species?
Despite conventional wisdom among gardeners, foresters and botanists that woody plants all "leaf out" at about the same time each spring, a new study organized by a Boston University biologist found a surprisingly wide span of as much as three months in leaf-out times.
A new study published in the Proceedings of the National Academy of Sciences by scientists at the University of Queensland, Australia, overturns a long-held theory in plant science.
Automated remote photography is a convenient, labor-saving research tool for tracking leaf function and doing forest research. But does photography mirror what's actually happening on the ground? A new study finds photography accurately tracks the timing of red pigments in the fall, but the timing of green in the spring and summer — not so much.
Trees, and more specifically, the leaves that adorn them, having predated humans foray into scientific learning, should harbor no mysteries at this point. However, nature continues to surprise us.
Hidden in the thick foliage of tropical forests a subfamily of colorful beetles hides the secrets of the earliest stages of social behavior, showing explicit signs of maternal instincts and care.
Phylliidae is a family of insects most commonly known as leaf insects or walking leaves, which can be found in Southeast Asia and South Asia to Australia. Although it is classified as a family, there is no general agreement on its classification, as many suggest that the family is actually a large taxon that should contain separate families of leaf insects. It is thought that this family has changed little over long periods of time, due to fossil evidence found of a forty-seven million year...
The Coco (Fagara coco or Zanthoxylum coco) is a species of evergreen tree native to Argentina and Bolivia. It grows in wild, mostly hilly, spinniferous (thorny or spiny) forests. Its habitat is found along the hilly forest of the Sierra Pampeana. This plant is found either in small isolated groups or standing alone. Other common names for this plant are cochucho or "smelly sauco". The Coco is a medium sized tree ranging from 20 to 26.25 feet tall. Its foliage is abundant and has paired...
