Article
Full-text available
1. Resilient pollination services depend on sufficient abundance of pollinating insects over time. Currently, however, most knowledge about the status and trends of pollinators is based on changes in pollinator species richness and distribution only. 2. Systematic, long-term monitoring of pollinators is urgently needed to provide baseline informati...
Article
The importance of wild bees for crop pollination is well established, but less is known about which species contribute to service delivery to inform agricultural management, monitoring and conservation. Using sites in Great Britain as a case study, we use a novel qualitative approach combining ecological information and field survey data to establi...
Article
Full-text available
Pollinator decline has attracted global attention and substantial efforts are underway to respond through national pollinator strategies and action plans. These policy responses require clarity on what is driving pollinator decline and what risks it generates for society in different parts of the world. Using a formal expert elicitation process, we...
Article
Agri-environment schemes are programmes where landholders enter into voluntary agreements (typically with governments) to manage agricultural land for environmental protection and nature conservation objectives. Previous work at local scale has shown that these features can provide additional floral and nesting resources to support wild pollinators...
Article
Full-text available
1. Pollinators experience large spatio‐temporal fluctuations in resource availability when mass‐flowering crops are rotated with resource‐poor cereal crops. Yet, few studies have considered the effect this has on pollinator population stability, nor how this might be mitigated to maintain consistent crop pollination services. 2. We assess the poten...

Full-text available
Bees provide a vital ecosystem service to agriculture by contributing to the pollination of many leading global crops. Human wellbeing depends not only on the quantity of agricultural yields, but also on the stability and resilience of crop production. Yet a broad understanding of how the diversity and composition of pollinator communities may infl...
Article
Full-text available
In a context of rapid global change, understanding how environmental stressors can impact phenotypic variation, and which phenotypic traits are predominantly affected can be particularly relevant. Indeed, potential pheno-typic modifications could affect the functionality of traits from taxa that are in decline but that are keystone species in many...
Article
Full-text available
Bumblebee pollination is crucial to the production of tomato in protected cultivation. Both tomato yield and flavor play important roles in attracting attentions from growers and consumers. Compared with yield, much less work has been conducted to investigate whether and how pollination methods affect tomato flavor. In this study, the effects of bu...
Article
Full-text available
Rising demand for food production poses a major threat to biodiversity by placing competing pressures on land. Diversified farming systems are one widely promoted nature-based solution to this challenge, which aim to integrate biodiversity-based ecosystem services into agricultural production. The underlying theory behind this approach is that dive...

Article
Full-text available
1. Trade in animal-pollinated crops plays an important role in global food systems: in many low-income countries, export of pollinated crops such as coffee and cocoa plays a significant role in livelihoods, while food systems in many higher income nations depend on international trade in these crops to satisfy their local demands. Losses of pollina...

In this report, we present the analysis of the different available biodiversity data streams at the EU and national level, both baseline biodiversity data and monitoring data. We assess how these biodiversity data inform and trigger policy action and identify the related challenges the different European countries and relevant EU agencies face and...
Chapter
Conservation biological control is commonly considered to be a key component of IPM because it is compatible with and complementary to many other approaches available in the IPM ‘toolbox’. However, despite significant study of conservation biological approaches in horticultural systems, uptake has been limited. Furthermore, whilst there are many st...

Observations are key to understand the drivers of biodiversity loss, and the impacts on ecosystem services and ultimately on people. Many EU policies and initiatives demand unbiased, integrated and regularly updated biodiversity and ecosystem service data. However, efforts to monitor biodiversity are spatially and temporally fragmented, taxonomical...

Full-text available
Pollinator declines have prompted efforts to assess how land-use change affects insect pollinators and pollination services in agricultural landscapes. Yet many tools to measure insect pollination services, require substantial landscape-scale data and technical expertise. In expert workshops, 3 straightforward methods (desk-based method, field surv...

Conference Paper
In recent years winter sown oilseed rape (OSR) production has decreased as the result of loss of control of an insect pest, the cabbage stem flea beetle (Psylliodes chrysocephala L.), due to the pest developing resistance to pyrethroid insecticides, and the EU ban on the use of neonicotinoid seed dressings. There is therefore an urgent need to deve...
Article
Full-text available
• Wild bees provide a critical ecosystem service by pollinating globally important crops. Documented bee declines, notably in agricultural landscapes, therefore threaten future food security. Yet, evaluations of methods to inventory bees are rarely carried out in different crops or focus specifically upon crop pollinating species. • We utilise stan...
Article
Urban hedges provide multiple ecosystem services including microclimate regulation, flood and pollution mitigation, and biodiversity provision. Their relatively compact nature may suit higher-density housing developments more readily than many other forms of green infrastructure. However, hedge plant species differ in their capacity to promote diff...
Article
Full-text available
Queen-worker conflict over the reproduction of males exists in the majority of haplodiplioidy hymenpteran species such as bees, wasps, and ants, whose workers lose mating ability but can produce haploid males in colony. Bumblebee is one of the representatives of primitively eusocial insects with plastic division labor and belongs to monandrous and...
