The factors shaping host–parasite interactions and epibiont communities in the variable rocky intertidal zone are poorly understood. California mussels, Mytilus californianus , are colonized by endolithic cyanobacterial parasites that erode the host shell. These cyanobacteria become mutualistic under certain abiotic conditions because shell erosion can protect mussels from thermal stress. How parasitic shell erosion affects or is affected by epibiotic microbial communities on mussel shells and the context dependency of these interactions is unknown. We used transplant experiments to characterize assemblages of epibiotic bacteria and endolithic parasites on mussel shells across intertidal elevation gradients. We hypothesized that living mussels, and associated epibacterial communities, could limit colonization and erosion by endolithic cyanobacteria compared with empty mussel shells. We hypothesized that shell erosion would be associated with compositional shifts in the epibacterial community and tidal elevation. We found that living mussels experienced less shell erosion than empty shells, demonstrating potential biotic regulation of endolithic parasites. Increased shell erosion was not associated with a distinct epibacterial community and was decoupled from the relative abundance of putatively endolithic taxa. Our findings suggest that epibacterial community structure is not directly impacted by the dynamic symbiosis between endolithic cyanobacteria and mussels throughout the rocky intertidal zone.

BACKGROUND: While pesticides are essential for crop protection and food security, they pose serious risks to human health and the environment. Agro‐input dealers can play an important role in mitigating pesticide risks, given that they are a major source of pesticides and plant health information for many developing‐country farmers. In this article, we assess the willingness of agro‐input dealers to offer integrated pest management‐based advisory services and promote pesticide risk reduction through a voluntary certification scheme. RESULTS: Using survey data from 557 agro‐input dealers in Uganda and a discrete choice experiment, we find that the proposed certification scheme is significantly valued by agro‐input dealers, particularly for its potential to provide training opportunities and ensure safety to human health and the environment. Agro‐input dealers have a positive attitude towards a certification scheme that restricts the sale of high‐risk pesticide products, especially if it stimulates additional income‐generating opportunities. Further analysis shows that preferences for voluntary certification attributes are influenced by certification experience, agro‐dealership experience, business ownership status and incidence of acute pesticide poisoning. CONCLUSION: The study findings demonstrate that agro‐input dealers are conscious of pesticide risks to human and environmental health and are keen to participate in a certification scheme promoting safer plant protection products. © 2024 The Author(s).

This paper draws upon a case study of education in the small Caribbean state of Saint Lucia (population 154,000) to examine how local knowledge and values can influence the education policy process. It is argued that recent research development initiatives have strengthened the ability of Saint Lucia to mediate international education agendas to suit its distinctive 'social ecology' and circumstances as a small state. Saint Lucians, it is argued, are reconceptualizing educational research in ways that better reflect the society's Kweyol-majority culture, oral traditions and postcolonial context. The boundaries of educational research are therefore being stretched to incorporate local knowledge and values and multiple modes of meaning-making. The paper argues that increased recognition of the epistemological issues and cultural values that are at the heart of efforts to strengthen research capacity can play a crucial role in democratizing the education policy process and educational research itself.

Objective: To create the first structured surgical report form for NBL with international consensus, to permit standardized documentation of all NBL-related surgical procedures and their outcomes. Summary of Background Data: NBL, the most common extracranial solid malignant tumor in children, covers a wide spectrum of tumors with significant differences in anatomical localization, organ or vessel involvement, and tumor biology. Complete surgical resection of the primary tumor is an important part of NBL treatment, but maybe hazardous, prone to complications and its role in high-risk disease remains debated. Various surgical guidelines exist within the protocols of the different cooperative groups, although there is no standardized operative report form to document the surgical treatment of NBL. Methods: After analyzing the treatment protocols of the SIOP Europe International Neuroblastoma Study Group, Children's Oncology Group, and Gesellschaft fuer Paediatrische Onkologie und Haematologie - German Association of Pediatric Oncology and Haematology pediatric cooperative groups, important variables were defined to completely describe surgical biopsy and resection of NBL and their outcomes. All variables were discussed within the Surgical Committees of SIOP Europe International Neuroblastoma Study Group, Children's Oncology Group, and Gesellschaft fuer Paediatrische Onkologie und Haematologie - German Association of Pediatric Oncology and Haematology. Thereafter, joint meetings were organized to obtain intercontinental consensus. Results: The "International Neuroblastoma Surgical Report Form" provides a structured reporting tool for all NBL surgery, in every anatomical region, documenting all Image Defined Risk Factors and structures involved, with obligatory reporting of intraoperative and 30 day-postoperative complications. Conclusion: The International Neuroblastoma Surgical Report Form is the first universal form for the structured and uniform reporting of NBL-related surgical procedures and their outcomes, aiming to facilitate the postoperative communication, treatment planning and analysis of surgical treatment of NBL.
