Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by a few dominant species or rely on high richness remains unclear. Using database from 89 studies (with 1475 locations), we partition the relative importance of richness, abundance, dominance for pollination; biological pest control; final yields in context ongoing land-use change. Pollinator enemy directly supported...
Agricultural management recommendations based on short-term studies can produce findings inconsistent with long-term reality. Here, we test the environmental sustainability and profitability of continuous no-till agriculture yield, soil water availability, N2 O fluxes. Using a moving window approach, investigate development stability several attributes as compared to conventional till over 29-year period at site in upper Midwest, US. Over decade is needed detect consistent effects no-till....
While an increasing number of studies indicate that the range, diversity and abundance many wild pollinators has declined, global area pollinator-dependent crops significantly increased over last few decades. Crop pollination to date have mainly focused on either identifying different guilds pollinating various crops, or factors driving spatial changes turnover observed in these communities. The mechanisms temporal stability for ecosystem functioning services, however, remain poorly...
ABSTRACT Land use change threatens global biodiversity and compromises ecosystem functions, including pollination food production. Reduced taxonomic α‐diversity is often reported under land change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased dampening loss. Additionally, studies focus on diversity, while other important components, phylogenetic can exhibit differential responses....
Abstract Plant–pollinator mutualisms are one of the several functional relationships that must be reinstated to ensure long‐term success habitat restoration projects. These unlikely reinstate themselves until all resource requirements pollinators have been met. By meeting these requirements, projects can improve their success. We hypothesized pollinator assemblage and structure stability plant–pollinator networks depend both on aspects surrounding landscape effort itself. predicted species...
ABSTRACT Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by few abundant species or rely on high richness remains unclear. Using a database from 89 systems, we partition the relative importance of abundance for pollination, biological pest control final yields in context on-going land-use change. Pollinator enemy directly supported independent abundance. Up 50%...
Abstract DNA sequencing technologies continue to advance the biological sciences, expanding opportunities for genomic studies of non‐model organisms basic and applied questions. Despite these opportunities, many next generation protocols have been developed assuming a substantial quantity high molecular weight (>100 ng), which can be difficult obtain study systems. In particular, ability sequence field‐collected specimens that exhibit varying levels degradation remains largely unexplored....
Abstract. Ecological intensification has been embraced with great interest by the academic sector but is still rarely taken up farmers because monitoring state of different ecological functions not straightforward. Modelling tools can represent a more accessible alternative measuring functions, which could help promote their use amongst and other decision-makers. In case crop pollination, modelling traditionally followed either mechanistic or data-driven approach. Mechanistic models simulate...
Abstract For the first time in more than a century, people across planet are migrating en mass from cities to rural areas. In this process of ‘exurbanisation’ humans rapidly converting natural and agricultural regions into low‐density housing. Despite scale exurban development its potential negative impact on biodiversity, little is known about how specific type land conversion impacts wild pollinators. study, we conduct an extensive survey pollinators peach agroecosystem investigate current...

Plant-pollinator interactions represent a crucial ecosystem function threatened by anthropogenic landscape changes. Disturbances that reduce plant diversity are associated with floral resource and pollinator declines. Establishing wildflower plantings is major conservation strategy targeting pollinators, the success of which depends on long-term persistence seeded communities. However, most pollinator-oriented seeding projects monitored for few years, making it difficult to evaluate...

Abstract A core issue in temporal ecology is the concept of trajectory—that is, when can ecologists have reasonable assurance that they know where a system going? In this paper, we describe non-random resampling method to directly address aspects scaling ecological observations by leveraging existing data. Findings from long-term research sites been hugely influential because their unprecedented longitudinal perspective, yet short-term studies more consistent with typical grant cycles and...
The societal and economic benefits of ecosystem services are both immense multi-faceted. To holistically quantify the contribution pollinators to agriculture requires measuring multiple indices crop production beyond yield. Here, we conduct a field-based hand pollination experiment measure effects self outcross pollen on fiber yield quality in conventionally managed cotton crops. First, determine how different treatments affect specific quality, including length fineness. Second, investigate...
Long-term experiments are important in evaluating ecosystem properties and processes that slow to develop or require proper evaluation over an appropriately variable climate. We repurpose the wealth of data accessible through forty-year-old Long-Term Ecological Research (LTER) network with a novel moving window algorithm meta-analysis approach ask if aspects study taxa environment alter extent research necessary detect consistent results, proportion spurious short-term trends. found...
ABSTRACT Agricultural management recommendations based on short-term studies can produce findings inconsistent with long-term reality. Here, we test the relative profitability and environmental sustainability of continuous no-till agriculture practices crop yield, soil moisture, N 2 O fluxes. Using a moving window approach, investigate development stability several attributes as compared to conventional till over 29-year period at site in upper Midwest, U.S. We find that decade is needed...
