A widely accepted approach to assess extinction risk, and a key source of data underpinning the IPBES report, is the IUCN Red List of Threatened Species (hereafter Red List). However, with only 9%of plants represented by assessments at the latest...

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. Our overall goal is to help increase...

Horticultural plants play various and critical roles for humans by providing fruits, vegetables, materials for beverages,and herbal medicines and by acting as ornamentals. They have also shaped human art, culture, and environments and thereby have...

A new study shows that even the most populous city in the United States contains significant stands of forest dominated by native tree species. The findings, which appear in the journal Ecological Applications, underscore the importance of studying...

In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e. manual outcross pollen addition without bagging) or manual...

For many species and seed sources used in restoration activities, specific seed germination
requirements are often unknown. Because seed dormancy and germination traits can be
constrained by phylogenetic history, related species are often...
