Scientific interest in the use of environmental microbiomes for risk assessment is rapidly growing, as exemplified by various EFSA opinions. In absence official regulatory guidelines on how to integrate assessment, aims this report are therefore determine whether microbiome studies can be used such purposes, and propose a roadmap integration assessments under EFSA's remit. The identifies current gaps (in terms knowledge from technical point view) barriers that might delay implementation methods, offers recommendations standardised (multi-)omics techniques purposes. Our main findings identified five priorities: (i) defining core (what it encompasses what made of, including identification bioindicators) assess impact any type disturbance; (ii) standardising methodologies protocols, sampling interpretation, guarantee comparability analyses; (iii) developing tools facilitate interpretation; (iv) collecting microbiome-based data shared, curated maintained databases; (v) setting up European Network Microbiome Laboratories reach an agreement standardise studies, interactions between researchers access or samples, actively include multiple stakeholders discussions involving assessment. There both short- longer-term priorities, all which highlight need mobilise concurrently different agencies institutions, well research. also points out capacity building training, acceptance emerging technology, communication issues. These will hopefully contribute elaboration widely accepted framework dealing with.

The global decline in biodiversity and insect populations highlights the urgent need to conserve ecosystem functions, such as plant pollination by solitary bees. Human activities, particularly agricultural intensification, pose significant threats these essential services. Changes land use alter resource nest site availability, pesticide exposure other factors impacting richness, diversity, health of bee species. In this study, we investigated yet another facet currently less well context: Microbial communities associated with wild bees play crucial roles larval development, metabolism, immunity overall health. However, drivers dynamics healthy microbiome are still poorly understood, especially regarding direct indirect effects on diversity composition microbial communities. We examined bacterial offspring materials Megachilid trap-nesting bee, Osmia bicornis, along a gradient intensification 16S rRNA gene metabarcoding.

Our findings provide new insights into shaping environmental transmission microbiomes. This understanding comprehending impacts intensive developing strategies mitigate effects.

Habitat loss is a primary driver of global biodiversity decline, negatively impacting many species, including native bees. One approach to counteract the consequences habitat through restoration, which includes transformation degraded or damaged habitats increase biodiversity. In this review, we survey bee restoration literature over last 14 years provide insights into how best promote diversity and abundance natural landscapes in North America. We highlight relevant questions concepts consider throughout various stages projects, categorizing them pre-, during-, post-restoration stages. emphasize importance planning species- site-specific strategies support bees, providing floral non-floral resources increasing nest site availability. Lastly, underscore significance conducting evaluations long-term monitoring following efforts. By identifying effective methods, success indicators, areas for future research, our review presents comprehensive framework that can guide land managers during urgent time restoration.

Abstract The implementation of omics technologies and associated bioinformatics approaches hold significant promise for generating additional evidence food feed risk assessments thereby enhancing the European Food Safety Authority (EFSA) capacity to deliver scientific opinions guidance documents in future. To explore this possibility, EFSA launched a Call development roadmap identify main actions needed wider use Omics future assessments. address objective, action outlines six project proposals. These proposals are based on comprehensive mapping state‐of‐the‐art research, EFSA's activities as well current planned from other relevant regulatory bodies organisations. outlined recommendations also some identified knowledge gaps highlight added value that further investments different & safety domains could bring. In addition, work addresses key challenges blockers might hinder integration assessment leverages opportunities cooperation with external stakeholders. Finally, provides suggestions how may more broadly effectively engage stakeholders science.

Abstract Wild pollinators and their microbiota are sensitive to land use changes from anthropogenic activities that disrupt landscape environmental features. As urbanization agriculture affect bee habitats, human-led disturbances driving in microbiomes, potentially leading dysbiosis detrimental fitness. This study examines the bacterial, fungal, plant compositions of small carpenter bee, Ceratina calcarata, its pollen provisions across an urban–rural divide. We performed metabarcoding C. calcarata Toronto by targeting 16S rRNA, ITS, rbcL regions. Despite similar composition diversity bees provisions, there was a greater microbial than bees. By characterizing differences use, climate, pesticide residues differentiate urban rural landscapes, we find areas support elevated levels more complex networks between microbes plants areas. However, may lead lower relative abundances known beneficial symbionts increased pathogens, such as Ascosphaera Alternaria fungi. Further, indicate dysregulate symbiosis. continue alter ever changing environments threaten crucial maintaining health.

Abstract The health of bees can be assessed through their microbiome, which serves as a biomarker indicating the presence both beneficial and harmful microorganisms within bee community. This study presents characterisation bacterial, fungal, plant composition on cuticle adult bicoloured sweat ( Agapostemon virescens ). These were collected using various methods such pan traps, blue vane traps sweep netting across northern extent habitat range. Non‐destructive employed to extract DNA from whole pinned specimens these wild bees. Metabarcoding 16S rRNA, ITS rbcL regions was then performed. found that method collection influenced detection certain microbial taxa. Among methods, net samples showed lowest fungal alpha diversity. However, minor differences in bacterial or beta diversity suggest no single is significantly superior others. Therefore, combination techniques cater broader spectrum detection. also revealed regional variations core microbiome A. comprises two bacteria, three fungi association, all are commonly detected other microbes remained consistent different locations. Further extensive studies microbiomes species landscapes will help uncover crucial relationships between pollinator environment.
