The Flora covers the biogeographic region of the moist, relictual, unglaciated southeastern North America: south of the glacial boundary and east of the “dry line” to the west that marks a marked floristic boundary to the Great Plains prairies to the...

Public gardens can help prevent detrimental effects of plant invasions by collecting and sharing data on taxa spreading from cultivation early in the invasion process, thereby acting as sentinels of plant invasion. Existing initiatives have called for...

Urgent solutions to global climate change are needed. Ambitious tree-planting initiatives, many already underway, aim to sequester enormous quantities of carbon to partly compensate for anthropogenic CO2 emissions, which are a major cause of rising...

Scientists’ research interests are often skewed toward charismatic organisms, but quantifying research biases is challenging. By combining bibliometric data with trait-based approaches and using a well-studied alpine flora as a case study, this...

Do all plant biologists worldwide have equal access to novel methods, enabling them to be equally productive, publish, and receive credit for their research? Or does reduced access to cutting‐edge techniques in countries with lower financial resources...

Botanical gardens have contributed to plant conservation through the maintenance of both living 20 and preserved plant specimens for decades. However, there is still a large gap in the literature 21 with regards to understanding the potential...

Indirect climate effects on tree fecundity that come through variation in size and growth
(climate-condition interactions) are not currently part of models used to predict future forests.
Trends in species abundances predicted from meta-...

This is a companion resource to a presentation given by Tim Boland, Polly Hill Arboretum, entitled The American Oaks: Diversity, Ecology, Identification as part of the "A Focus On Sustainability" Webinar Series. 

Changes in phenology induced by climate change occur across the globe with important
implications for ecosystem functioning and services, species performance and trophic
interactions. Much of the work on phenology, especially leaf out and...

Ten years ago the Royal Botanic Gardens Victoria embarked on an ambitious project to collect, treat and distribute storm water from the catchment within and around the botanic garden. The infrastructure of wetlands filtration, a sophisticated water ...

Plant and fungal specimens provide the auditable evidence that a particular organism
occurred at a particular place, and at a particular point in time, verifying past occurrence
and distribution. They also document the aspects of human...

The adoption of a Global Strategy for Plant Conservation (GSPC) in 2002 and its subsequent renewal in 2010 were significant milestones for the Convention on Biological Diversity. Not only did this strategy, its objectives and targets provide a valuable...

Extinction rates are expected to increase during the Anthropocene. Current extinction rates of plants and many animals remain unknown. This study represents the first effort to quantify extinctions among the vascular flora of North America north of...

This Research Topic aims to synthesize and inspire the frontier of integrative and translational research using herbarium collections to highlight their unharvested potential for addressing outstanding research questions and societal challenges. The...

Contemporary climate change is exposing plant populations to novel combinations of
temperatures, drought stress, and other abiotic and biotic conditions. These changes are
rapidly disrupting the evolutionary dynamics of plants. Despite...

Botanic gardens and arboreta have evolved significantly from their origins as oases
reserved for the elite, to the conservation powerhouses they are today, visited by
over half a billion people annually. Now, with their sophisticated...

Disease detection is one of many vital missions that biodiversity collections play, along with environmental assessment, online education, and detection of crop disease and potential bioterror
organisms, among many other uses. But the COVID-19...

Palms (Arecaceae) are a relatively speciose family and provide materials for food, construction, and handicraft, especially in the tropics. They are frequently used as paleo-indicators for megathermal climates, and therefore, it is logical to predict...
