Significance In 2014, a presidential memorandum called for an assessment of the nation’s pollinators, in response to growing awareness their economic importance and recent declines. We assess, first time our knowledge, status trends wild bee abundance potential impacts on pollination services across United States. develop national maps abundance, report land-use–driven changes over time, relate them agricultural demand pollination. estimate uncertainty findings, so future research can target...
Background and AimsCrop pollination by bees other animals is an essential ecosystem service. Ensuring the maintenance of service requires a full understanding contributions landscape elements to pollinator populations crop pollination. Here, first quantitative model that predicts abundance on described tested.
Although soil microbial communities are known to play crucial roles in the cycling of nutrients forest ecosystems and can vary by plant species, how microorganisms respond subtle gradients genetic variation is just beginning be appreciated. Using a model Populus system common garden with replicated clones genotypes, we evaluated biomass community composition as quantitative traits. Two main patterns emerged. (1) Plant genotype influenced nitrogen soils under genotypes angustifolia, F1,...
Habitat loss and fragmentation are major threats to biodiversity. Establishing formal protected areas is one means of conserving habitat, but socio‐economic political constraints limit the amount land in such status. Addressing conservation issues on lands outside also necessary. In this paper we develop a spatially explicit model for analyzing consequences alternative land‐use patterns persistence various species market‐oriented economic returns. The biological uses habitat preferences,...
Abstract Natural infrastructure such as parks, forests, street trees, green roofs, and coastal vegetation is central to sustainable urban management. Despite recent progress, it remains challenging for decision-makers incorporate the benefits of natural into design planning. Here, we present an approach support greening cities by quantifying mapping diverse now in future. The relies on open-source tools, within InVEST (Integrated Valuation Ecosystem Services Tradeoffs) software, that compute...
Land-use change significantly contributes to biodiversity loss, invasive species spread, changes in biogeochemical cycles, and the loss of ecosystem services. Planning for a sustainable future requires thorough understanding expected land use at fine spatial scales relevant modeling many ecological processes dimensions appropriate regional or national-level policy making. Our goal was construct parameterize an econometric model land-use project year 2051 scale across conterminous United...
Abstract Each year, millions of kilograms insecticides are applied to crops in the US. While insecticide use supports food, fuel, and fiber production, it can also threaten non-target organisms, a concern underscored by mounting evidence widespread decline pollinator populations. Here, we integrate several public datasets generate county-level annual estimates total ‘bee toxic load’ (honey bee lethal doses) for US between 1997–2012, calculated separately oral contact toxicity. To explore...
Abstract Native pollinators and, particularly bees, are a critical component of agricultural systems. Unfortunately, many factors leading to their declines, including habitat loss. Consequently, approaches have emerged that aim restore pollinator in managed landscapes. A widely adopted technique Europe and North America is the planting flowering shrubs forbs along field edges. These habitats usually include variety species, chosen because they attractive flower continuously over those...
In an increasingly urbanized world, the concepts of ecosystem services and nature-based solutions can help tackle grand challenges. However, ambiguity in their definitions relationship between two complicates comprehensive research efforts as well effective application policy planning urban systems. This paper presents a framework to clarify explicitly relate concepts, enhancing applicability management Within framework, addressing challenges serves starting point for development...
Abstract The evolutionary analysis of community organization is considered a major frontier in biology. Nevertheless, current explanations for structure exclude the effects genes and selection at levels above individual. Here, we demonstrate genetic basis structure, arising from fitness consequences interactions among species (i.e., interspecific indirect or IIGEs). Using simulated natural communities arthropods inhabiting North American cottonwoods (Populus), show that when comprising...

We used empirical and modeling approaches to examine effects of plant breeding systems on demographic responses habitat fragmentation. Empirically, we investigated local flowering density pollination population size mate availability in a common, self‐incompatible purple coneflower, Echinacea angustifolia, growing fragmented prairie habitat. Pollination recruitment increased with weighted around individual plants. This positive dependence is an Allee effect. In addition, mean compatibility...
Viral particles in stool samples from wild-living chimpanzees were analysed using random PCR amplification and sequencing. Sequences encoding proteins distantly related to the replicase protein of single-stranded circular DNA viruses identified. Inverse was used amplify sequence multiple small viral genomes. The genomes size genome organization vertebrate circoviruses plant geminiviruses but with a different location for stem-loop structure involved rolling circle replication. genes these...
Abstract Enhancing floral resources is a widely accepted strategy for supporting wild bees and promoting crop pollination. Planning effective enhancements can be informed with pollination service models, but these models should capture the behavioural spatial dynamics of service‐providing organisms. Model predictions, hence management recommendations, are likely to sensitive dynamics. We used two established pollinator foraging investigate whether habitat enhancement improves visitation;...
With more than half the world's population living in urban areas, most of people's potential to receive ecosystem service benefits occurs cities. However a straightforward, replicable approach quantifying multiple services has yet emerge, so planning decisions often overlook value nature could provide people. Urbanization is likely increase development pressure on many forms green spaces across cities, particularly for golf courses that represent substantial part areas United States. Here,...
The increasing pressure on land resources for food and energy production along with efforts to maintain natural systems necessitates the development of compatible uses that maximize co-benefits multiple ecosystem services. One such sharing opportunity is restoration management native grassland vegetation beneath ground-mounted solar facilities, which can both protect biodiversity restore related In this paper, we applied InVEST modeling framework investigate potential response four services...
