Ten golden rules for reforestation to optimize carbon sequestration, biodiversity recovery and livelihood benefits

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...

Plant scientists’ research attention is skewed towards colourful, conspicuous and broadly distributed flowers

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...

Continent-wide tree fecundity driven by indirect climate effects

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-...

The PhenObs initiative – A standardised protocol for monitoring phenological responses to climate change using herbaceous plant species in botanical gardens

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...

Can an ambitious breeding effort save North America’s ash trees?

Since a devastating fungal blight popped up in the Bronx Zoo in 1904 and went on to kill at least 3 billion chestnut trees, North American forests have been swept by one plague after another, including a fungus that kills elms and an aphidlike insect...

Plant and fungal collections: Current status, future perspectives

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...

Vascular plant extinction in the continental United States and Canada

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...

Integrative and Translational Uses of Herbarium Collections Across Time, Space, and Species

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...

Botanic garden solutions to the plant extinction crisis

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...

Climate change winners and losers: The effects of climate change on five palm species in the Southeastern United States

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...

Wild bee declines linked to plant‐pollinator network changes and plant species introductions

Climate change and an increase in disturbed bee habitats from expanding agriculture and development in northeastern North America over the last 30 years are likely responsible for a 94 per cent loss of plant-pollinator networks, York University...

The global tree restoration potential

The restoration of trees remains among the most effective strategies for climate change
mitigation.We mapped the global potential tree coverage to show that 4.4 billion hectares
of canopy cover could exist under the current climate....

An algorithm competition for automatic species identification from herbarium specimens

Plant biodiversity is threatened, yet many species remain undescribed. It is estimated that >50% of undescribed species have already been collected and are awaiting discovery in herbaria. Robust automatic species identification algorithms using...

Reshaping the future of ethnobiology research after the COVID-19 pandemic

A geographically diverse group of 29 ethnobiologists addresses three common themes in response to the COVID-19 global health crisis: impact on local communities, future interactions between researchers and communities, and new (or renewed) conceptual...

Access to crop digital information and the sharing of benefits derived from its use: Background and perspectives

Today's genebanks are essential to maintaining the resilience of the global agricultural system in the face of climate change, new pests and diseases, shifts in trade and dietary preferences, natural
resource limitations, and armed conflicts....

Caution Needed When Predicting Species Threat Status for Conservation Prioritization on a Global Scale

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...

Applying the Zoo Model to Conservation of Threatened Exceptional Plant Species

Maintaining a living plant collection is the most common method of ex situ conservation for plant
species that cannot be seed banked i.e. “exceptional” species. Viability of living collections, and their value for future conservation efforts,...

Cyanea kuhihewa: Rediscovering one of Hawai'i's rarest trees

With 90% of its nearly 1,400 native plants classified as endemic, Hawai'i has one of the highest levels of endemism of any floristic region of the world. Although Cyanea is one of the most species-rich flowering plant genera in Hawai'i, nearly half of...

Bartlett: Needle Diseases of Conifers

Needlecast and needle blight are terms applied to a variety of foliage disorders of many coniferous species. These diseases are usually more severe on young trees or on trees growing outside of their natural range. Disease severity and corresponding...

Mycorrhizas for a changing world: Sustainability, conservation, and society

Mycorrhizal fungi, of all types, hold huge significance for our planet and society. By forming mutualistic symbioses with the vast majority of land plants, mycorrhizas play an essential role
in the formation and maintenance of global ecosystems...
