Codesigning synergies among ecological, social, and economic benefits with landscape‐scale agri‐environmental schemesNARA Subscribed
Global farmland biodiversity is declining rapidly, threatening both natural ecosystems and agricultural production. Although agri‐environmental schemes incentivize farmers to adopt environmentally friendly measures, the spatial mismatch between their local implementation and the landscape‐scale habitat requirements of farmland species has been criticized. Landscape‐scale agri‐environmental schemes (LAESs) are a promising appro...
Multiple Key Hosts and Network Structure Shape Viral Prevalence Across Multispecies Communities of BeesNARA Subscribed
Emerging infectious diseases (EIDs) threaten biodiversity, yet identifying key host species in complex ecological communities remains a major challenge. Here, we develop a quantitative framework combining field data, epidemiological modelling, simulations, and Bayesian inference to pinpoint key viral hosts in multispecies bee communities. Using flower–visitor interaction data and molecular virus screening, we estimate species‐...
Proximity to natural habitat is known to enhance pollination services in large‐scale agriculture, but it remains unclear whether this holds in tropical smallholder farms. These systems are embedded in ecologically complex landscapes, central to global food security, and depend heavily on biodiversity‐derived ecosystem services. We conducted a systematic review and meta‐analysis of 35 studies assessing the relationship between...
To counteract the decline of biodiversity in intensively used agricultural landscapes, a diversity of local conservation interventions, including on-field measures, such as extensification of cereal production, and off-field measures, such as flower strips, is taken. Pollinators, among which wild bees are of particular importance, are a focal group of biodiversity conservation. Although several studies have shown positive loca...
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use 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 β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...
Urbanization alters the spatiotemporal dynamics of plant–pollinator networks in a tropical megacityNARA Subscribed
Urbanization is a major driver of biodiversity change but how it interacts with spatial and temporal gradients to influence the dynamics of plant–pollinator networks is poorly understood, especially in tropical urbanization hotspots. Here, we analysed the drivers of environmental, spatial and temporal turnover of plant–pollinator interactions (interaction β ‐diversity) along an urbanization gradient in Bengaluru, a South India...
Taxonomic and functional homogenization of farmland birds along an urbanization gradient in a tropical megacityNARA Subscribed
Urbanization is a major driver of land use change and biodiversity decline. While most of the ongoing and future urbanization hotspots are located in the Global South, the impact of urban expansion on agricultural biodiversity and associated functions and services in these regions has widely been neglected. Additionally, most studies assess biodiversity responses at local scale (α‐diversity), however, ecosystem functioning is...
Worldwide pollinator declines lead to pollination deficits in crops and wild plants, and managed bees are frequently used to meet the increasing demand for pollination. However, their foraging can be affected by flower availability and colony size. We investigated how mass‐flowering oilseed rape (OSR) can influence the pollen resource use of small and large honey bee ( Apis mellifera L.) and bumble bee ( Bombus terrestris L.)...

Land use intensification alters ecosystem multifunctionality via loss of biodiversity and changes to functional compositionNARA Subscribed
Global change, especially land‐use intensification, affects human well‐being by impacting the delivery of multiple ecosystem services (multifunctionality). However, whether biodiversity loss is a major component of global change effects on multifunctionality in real‐world ecosystems, as in experimental ones, remains unclear. Therefore, we assessed biodiversity, functional composition and 14 ecosystem services on 150 agricultur...
A global quantitative synthesis of local and landscape effects on wild bee pollinators in agroecosystemsNARA Subscribed
Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, we modelled the relative effects of landscape composition (nesting and floral resources within foraging distances), landscape configuration (patch shape, interpatch connectivity and habitat aggregation) and farm management (organic vs. conventional...
