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...

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...

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....

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....

Can invasive species replace native species as a resource for birds under climate change? A case study on bird-fruit interactions

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. Despite the importance of these autumn interactions, their potential to shift with...

Lightning Protection for Trees

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). When...

Network modelling, citizen science and targeted interventions to predict, monitor and reverse bee decline

Pollination is fundamentally important to ecosystem function and human food security.
Recent reports of dramatic insect declines, and pollinator decline in particular,
have increased public awareness and political motivation to act to...

Distributions and Conservation Status of Carrot Wild Relatives in Tunisia: A Case Study in the Western Mediterranean Basin

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
in knowledge of taxonomy, distributions, and...

Urban plant diversity in Los Angeles, California: Species and functional type turnover in cultivated landscapes

Urbanization is a large driver of biodiversity globally. Within cities, urban trees, gardens, and residential yards contribute extensively to plant biodiversity, although the consequences and mechanisms of plant cultivation for biodiversity are...

How do climate change experiments alter plot-scale climate?

To understand and forecast biological responses to climate change, scientists frequently use field
experiments that alter temperature and precipitation. Climate manipulations can manifest in complex ways, however, challenging interpretations of...

Plants are Cool, Too: #SciComm, media relations, and a botanist on Mars

The Plant Conservation Alliance and the Smithsonian’s Department of Botany welcomed Chris Martine, David Burpee Professor of Plants Genetics & Research and Director of the Manning Herbarium at Bucknell University, to present “Plants are Cool, Too...

Succulent plant diversity as natural capital

Drought‐tolerant plants are increasingly recognized as a resource to mitigate the consequences
of climate change. Succulent plants use stored water to sustain metabolism
during regular droughts; succulence is a highly successful...

Sowing the seeds for interdisciplinary plant research and development in the Tropical Andes

In the Tropical Andes millions of people depend upon the use of wild and domesticated
biodiversity for their livelihoods, but the complex interactions between the
ecological and social components of the region’s ecosystems remain poorly...

Contemporary climatic analogs for 540 North American urban areas in the late 21st century

A major challenge in articulating human dimensions of climate change lies in translating global climate forecasts into impact assessments that are intuitive to the public. Climateanalog mapping involves matching the expected future climate at a...

Shifts in the Abiotic and Biotic Environment of Cultivated Sunflower under Future Climate Change

Sunflower is a unique model species for assessing crop responses and adaptation to climate change. We provide an initial assessment of how climate change may influence the abiotic and biotic environment of cultivated sunflower across the world. We find...

Saving plants, saving ourselves

The future of the Earth and its inhabitants has never been more uncertain, but there
is still time for us to prevent further catastrophe. Plant scientists have a crucial role
to play in the preservation of plant biodiversity and crop...

Extreme Botany: The Precarious Science of Endangered Rare Plants

They don’t make the headlines the way charismatic animals such as rhinos and elephants do. But there are thousands of critically endangered plants in the world, and a determined group of botanists are ready to go to great lengths to save them.

Phylogeny and source climate impact seed dormancy and germination of restoration relevant forb species

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...
