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...
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...
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...
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...
Contact your elected representatives and let them know how you feel about plants, our web of life, and the ecosystem services we all depend upon:
- Ask them to cosponsor H.R. 1572 The Botanical Sciences and Native Plant Materials Research, ...
Indigenous communities rely extensively on plants for food, shelter, and medicine. It is still unknown, however, to what degree their survival is jeopardized by the loss of either plant species or
knowledge about their services. To fill this gap...
Born as a center for the treatment of addiction and mental health and for the research on traditional Amazonian medicine, the Takiwasi Center, located in the Peruvian high-Amazon, over more than 25 years of existence has developed a series of parallel...
North American forests and forest management institutions are experiencing a wide range of significant ecological disturbances and socioeconomic changes, which point to the need for enhanced resilience. A critical capacity for resilience in...
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...
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...
Recent studies have shown that the use of native plants by landscape architects and contractors in the southeastern United States has increased as has the clientele interest level in native plants. Recommendations to increase the use of native species...
Foresters and horticulturists should be aware of the risks of invasive species and should be updated on a regular basis regarding emerging pest threats. In the Pacific Northwest, many new potential threats to natural ...
This article profiles past and present deforestation and reforestation in the U.S. Virgin Islands, along with the geography and ecology of the three islands. The islands of St. Thomas and St. John form one ecological and cultural unit, whereas St....
Deploying well-adapted and ecologically appropriate plant materials is a core component of successful restoration projects. The USDA Forest Service has developed generalized provisional seed zones that can be applied to any plant species in the United...
Darrel Morrison discusses why he is intrigued by the value of linking ecology and ecological processes with art and music in the design of landscapes that might be considered “ecological art.” The products of ecological art have the potential to be,...
In the fragmented ecosystems where we live and work, the importance of diversity in our landscapes cannot be over emphasized. Diversity of native plants, insects, mammals, birds, amphibians…. They all play a crucial role in sustaining a healthy...
