As land-use patterns change over time, some pollinating insects continue to decline both in abundance and diversity. This is due, in part, to reductions in floral resources that provide sufficient nectar and pollen.
As the number of local climate adaptation plans has rapidly grown during the past ten years in
response to increasing threats of climate change, cities and various organizations offer new insights
Developing new genotypes of plants is one of the key options for adaptation of agriculture to climate change. Plants may be required to provide resilience in changed climates or support
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).
North America’s agricultural and natural landscapes are vital to feeding humanity—they are home to many populations of important food plants and their wild relatives.
Agriculture is comprised of managed ecosystems, which can include forests, rangelands
and crops; these managed ecosystems are vital resources, providing a host
Conifers are commonly planted in North America to provide year-round screening, as windbreaks or as focal trees in the landscape.
Biodiversity in and across food and agriculture systems provides tremendous value to present and future generations. However, across the world we are losing genes, species, and ecosystems faster than we can account for them.
Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant
species, are sources of valuable genetic resources for crop improvement. Persisting gaps
