Wild fruits are an important food source for many north temperate-breeding landbirds during autumn migration and, in turn, birds provide the service of seed dispersal.
Sonic tomography, or the use of sound waves to detect decay in trees, is a relatively new technology available to arborists.
Thousands of trees are struck by lightning every year. These trees will have varying degrees of damage ranging from complete shattering and destruction of the tree, to a slow lingering death, to virtually no apparent damage at all (Figure 1).
For more than two centuries, biodiversity collections have served as the foundation for scientific investigation of and education about life on Earth. The collections that have been assembled in

Urbanization is a large driver of biodiversity globally.
Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
