Innovative solutions for the wine sector: the role of startups
The economic globalisation has opened new pathways for commerce and triggered a logistical revolution, which in turn has produced enormous technological innovations. In this context, the role of startups is becoming increasingly crucial since they are positioning themselves as innovation enablers among large and small companies. Between these innovations, IoT, Big Data Analytics and Blockchain can be used in various domains, among which the logistics of the whole wine supply chain. Here we will consider some of the issues and needs that arise in this market sector, showing how Wenda, a startup born in Bologna in February 2015 that works to improve sustainability and traceability in Food & Beverage supply chains, has been able to leverage IoT, Big Data Analytics and Blockchain to empower the wine supply chain with solutions that enable wine traceability throughout the distribution and the after-buying-in preservation and commercialisation phases
Effect of api-bioxal® and apiherb® treatments against Nosema ceranae infection in Apis mellifera investigated by two qPCR methods
Nosema ceranae is a worldwide distributed midgut parasite of western honey bees, leading to dwindling colonies and their collapse. As a treatment, only fumagillin is available, causing issues like resistance and hampered bee physiology. This study aimed to evaluate ApiHerb® and Api-Bioxal® as treatments against N. ceranae. The efficacy was tested using two qPCR methods based on the 16S rRNA and Hsp70 genes. In addition, these methods were compared for their aptitude for the quantification of the infection. For this, 19 colonies were selected based on the presence of N. ceranae infections. The colonies were divided into three groups: treated with ApiHerb, Api-Bioxal with previous queen caging and an untreated control. All colonies were sampled pre- and post-treatment. The bees were analyzed individually and in duplicate with both qPCR methods. All bees in the pre-treatment tested positive for N. ceranae. Both treatments reduced the abundance of N. ceranae, but ApiHerb also decreased the prevalence of infected bees. Analysis with the 16S rRNA method resulted in several orders of magnitude more copies than analysis with the Hsp70 method. We conclude that both products are suitable candidates for N. ceranae treatment. From our analysis, the qPCR method based on the Hsp70 gene results as more apt for the exact quantification of N. ceranae as is needed for the development of veterinary medicinal products
Microbiome network in the pelagic and benthic offshore systems of the northern Adriatic Sea (Mediterranean Sea)
Because of their recognized global importance, there is now the urgent need to map diversity and distribution patterns of marine microbial communities. Even if available studies provided some advances in the understanding the biogeographical patterns of marine microbiomes at the global scale, their degree of plasticity at the local scale it is still underexplored, and functional implications still need to be dissected. In this scenario here we provide a synoptical study on the microbiomes of the water column and surface sediments from 19 sites in a 130 km2 area located 13.5 km afar from the coast in the North-Western Adriatic Sea (Italy), providing the finest-scale mapping of marine microbiomes in the Mediterranean Sea. Pelagic and benthic microbiomes in the study area showed sector specific-patterns and distinct assemblage structures, corresponding to specific variations in the microbiome network structure. While maintaining a balanced structure in terms of potential ecosystem services (e.g., hydrocarbon degradation and nutrient cycling), sector-specific patterns of over-abundant modules-and taxa-were defined, with the South sector (the closest to the coast) characterized by microbial groups of terrestrial origins, both in the pelagic and the benthic realms. By the granular assessment of the marine microbiome changes at the local scale, we have been able to describe, to our knowledge at the first time, the integration of terrestrial microorganisms in the marine microbiome networks, as a possible natural process characterizing eutrophic coastal area. This raises the question about the biological threshold for terrestrial microorganisms to be admitted in the marine microbiome networks, without altering the ecological balance
Conservation status of Apis mellifera ruttneri inferred from whole genome sequences
Apis mellifera ruttneri is the native honey bee subspecies from the Maltese islands (Malta, Comino and Gozo). This
African-lineage subspecies is adapted to the harsh environmental conditions and to the limited forage season of these
islands. For many years, it was considered highly hybridized, due to the large and sustained importation of foreign
subspecies, especially A. m. ligustica, perceived by many beekeepers as superior or for commercial reasons. Recent
studies based on morphometry and mitochondrial DNA have suggested the occurrence of A. m. ruttneri, particularly
in the main island. Conservation initiatives and a breeding program have been developed, but to date its conservation
status is not fully known. As part of the MEDIBEES project, here, over 50 A. m. ruttneri georeferenced colonies
collected from across Malta, as well as 50 several reference subspecies (A. m. ligustica, A. m. siciliana, A. m. iberiensis,
A. m. sahariensis, and A. m. intermissa) were whole genome sequenced. The population structure and admixture were
assessed from genome-wide single nucleotide polymorphisms using model and distance based-methods. The results
show varying levels of admixture proportions of A. m. ruttneri with C-lineage honey bees across Malta but also a
shared ancestry with the honey bees of north Africa, consistent with the putative natural colonization from Africa in
ancient times.info:eu-repo/semantics/publishedVersio
MEDIBEES: Monitoring the Mediterranean honey bee subspecies and their resilience to climate change for the improvement of sustainable agro-ecosystems
Beekeeping provides livelihood for hundreds of thousands of beekeepers in the Mediterranean area. This activity relies
on a number of different indigenous Apis mellifera subspecies, adapted to the very diverse and harsh conditions of the
region. Climate change is expected to increase the stress factors affecting bees, especially in this region, reducing both
pollination efficiency and production potential. Unfortunately, our ability to address this problem is limited by the
incomplete knowledge of the natural adaptation mechanisms developed by the different subspecies. In order to
increase the knowledge base for future selection programs to improve bee populations for environmental changes,
the MEDIBEES project is being developed. It includes 9 partners from 8 Mediterranean countries on all three shores of
the Mediterranean, covering 10 local A. mellifera subspecies, which represents a remarkable though understudied
proportion of the species genetic diversity. The project aims to: a) unravel the differential genetic background of
Mediterranean subspecies, b) understand their adaptation to local conditions, and c) characterize their resistance to
climate change. To achieve the objectives, colonies belonging to the local subspecies will be studied phenotypically to
determine their behavior under environmental conditions, covering survival, sensitivity to pests/pathogens, behavior,
physiology and reproduction which will be completed by gene expression and transcriptomic assays. In addition,
complete genomes of field and laboratory samples will be sequenced to find genes putatively involved in adaptation
and to develop new genetic tools to characterize honey bee populations according to their resistance to
environmental stress factors. This effort will encourage the use of local subspecies, to make them more attractive and
avoid importing foreign breeds, and will lay the foundation for future selection programs. Besides, the valorization of
honey by both promoting its use and developing quality labels, and the evaluation of beekeeping by-products as
modifiers of soil fertility and biota are also approached to help the beekeepers improve the sustainability of their farms
in an economical and environmental sound manner.Medibees part of the PRIMA programme supported by the European Unioninfo:eu-repo/semantics/publishedVersio
Beekeeping in the Mediterranean: a medibees survey on practices, trends and challenges
MEDIBEES is a PRIMA funded project that aims to identify honeybee colonies and
subspecies that are most resilient to climate change and common pathogens throughout
the Mediterranean region. Honeybees are critical to sustainable agricultural systems and
the project aims to contribute to sustainability in the context of the increased desertification
of the region due to climate change.
As part of this project an intensive investigation of beekeeping was carried out within
the consortium, with the objectives of 1) understanding the main practices in place, 2)
identifying trends and challenges faced by beekeepers. This would help guide the consortium
in framing research questions that are rooted in the requirements of the stakeholders. A
questionnaire was therefore developed and circulated among beekeepers from Algeria,
Egypt, Italy, Jordan, Lebanon, Malta, Portugal, Spain and Turkey in late June 2021. To date,
over 1300 detailed responses have been collected. This study has yielded an important first
profile of the nature of the apicultural industry for many of these participating countries.
In this presentation, a description of the socio-demographics and the diverse management
practice in place among beekeepers across the Mediterranean will be presented. In
addition, important first-time data on the distribution of hives, the main sources of losses
including current biotic and abiotic threats, the characteristics and ecological trends of
both native and introduced honey bee subspecies in the different geographical regions
will be described as experienced by the major stakeholders ie beekeepers. Finally, notably
and overwhelmingly, beekeepers from the Mediterranean region list changes in weather
patterns as the major factor affecting colony losses and profitability. This was followed
closely by indiscriminant use of agricultural insecticides and urbanisation.info:eu-repo/semantics/publishedVersio
Main practices, challenges and expected solution identified in the Mediterranean beekeeping industry
Globally honeybees are threatened by a plethora of biotic and abiotic stressors. One factor of great concern is climate
change due to its direct impact on wild and agricultural ecosystems. Indeed beekeeping, with its symbiotic interdependence
with vegetation, is an industry that will be strongly affected by climate change. Although the Mediterranean is a region
that is highly vulnerable to climate change, no study has comprehensively analysed the possible effects on honeybees. The
MEDIBEES project aims to remedy this situation by studying the honeybee subspecies native to the Mediterranean region
and their resilience to climate change, in an attempt to safeguard the beekeeping sector. In this framework, the following
approaches were adopted to determine the common Practices, Challenges and Problems in the region and to identify
scientific gaps and solutions expected by beekeepers:
• Review of the effects of biotic and abiotic stressors on honeybee colonies as well as legislation in the MEDIBEES
consortium to identify common threats.
• Study of current challenges, priority areas considered by beekeepers as important to survive as an industry, beekeeping
practices and existing resources in each country to determine common trends and challenges across the Mediterranean.
• Analysis of the responses to a questionnaire distributed among 1160 beekeepers to obtain information on stakeholder
practices, challenges faced and the main problems encountered.
In this way, a profile of beekeeping activity and beekeepers in the region was obtained. The main challenges and problems
identified were: a) changes in weather patterns that could be affect colony dynamics, production losses and increasing
mortality; b) of incidence of pathogens in the area (Varroa destructor, Nosema ceranae, SBV and DWV) and the lack
of training programmes to control them; c) agricultural insecticides and acaricide residues. As main areas of interest,
beekeepers pointed out the possible existence of adapted ecotypes, the need for training to distinguish between hybrids
and purebreds, and the study of the effect that climate change will have on phenology and plant availability and on changes
in the distribution areas of pathogens in the area.

Treatments of honey bee colonies affected by Varroa destructor in organic apiculture
The organic honey bee productions are provided for in the EU Regulation 1804/99. Notwithstanding the beekeeping industry deserves a considerable economic importance to the whole organic market of the EU, limited action is paid in favour of the organic beekeeping. A noticeable exception to this are the huge research efforts on the disease control, which is mainly due to the lack of useful and not contaminating remedies against severe pests hitting the honey bees in the whole EU.
To avoid the honey contamination with treatment residues is paramount and fosters researche on soft chemicals like oxalic acid, which is of utmost impor-tance not only in organic, but also in conventional contexts.
The Authors are presenting here a synthetic review on the treatments against the varroosis with OA and on their research to optimise the use of the substance in different Italian environments
General beekeeping practices and main stressors identified by beekeepers in the Mediterranean
Beekeeping is an ecologically and economically important activity in the Mediterranean that is increasingly under
threat from a combination of factors. In the MEDIBEES (Monitoring the Mediterranean honey bee subspecies and their
resilience to climate change for the improvement of sustainable agro-ecosystems) PRIMA project we aim to identify
honey bees that show resilience to stressors associated with climate change. An important first step in our work was
to establish baseline data of practices in the region through the administering of a questionnaire on the beekeeping
practices. Over 1022 responses were received from beekeepers in Algeria, Egypt, Jordan, Italy, Lebanon, Malta, Spain,
Portugal and Turkey.
Beekeeping was overwhelmingly male dominated (ratio 9:1) and practiced largely by the middle-aged (mainly
between 40-50 years). The majority of beekeepers reported having 10-50 boxes with the exceptions of Algeria and
Jordan where the majority reported keeping more than 100 hive boxes. Across the Mediterranean the Langstroth hive
box was most commonly used. Despite the perception of migratory beekeeping being frequently practiced, only
Lebanon and Turkey reported significant levels of transhumance (>50.0 and 70.0% of beekeepers respectively). 51.2%
of beekeepers reported practicing queen rearing with the majority of these (51.4%) reporting re-queening their
colonies every 2 years. Interestingly, the majority of all beekeepers agreed with the statement that their native honey
bee is endangered where pesticide use, lack of adequate forage and parasite infestations such as the Varroa mite
were repeatedly cited as causing the greatest losses to honey bees in general. Climate change and urbanisation were
also linked with colony losses by causing habitat loss. Supplementary feeding was reported to be an integral part of
beekeeping in this region, with beekeepers reporting using between 0-5kg, closely followed by 6-10 kg of additional
sugars.MEDIBEES part of the PRIMA programme supported by the European Unioninfo:eu-repo/semantics/publishedVersio
Identification of genetic variants associated with Huntington's disease progression: a genome-wide association study
Background Huntington's disease is caused by a CAG repeat expansion in the huntingtin gene, HTT. Age at onset has been used as a quantitative phenotype in genetic analysis looking for Huntington's disease modifiers, but is hard to define and not always available. Therefore, we aimed to generate a novel measure of disease progression and to identify genetic markers associated with this progression measure. Methods We generated a progression score on the basis of principal component analysis of prospectively acquired longitudinal changes in motor, cognitive, and imaging measures in the 218 indivduals in the TRACK-HD cohort of Huntington's disease gene mutation carriers (data collected 2008–11). We generated a parallel progression score using data from 1773 previously genotyped participants from the European Huntington's Disease Network REGISTRY study of Huntington's disease mutation carriers (data collected 2003–13). We did a genome-wide association analyses in terms of progression for 216 TRACK-HD participants and 1773 REGISTRY participants, then a meta-analysis of these results was undertaken. Findings Longitudinal motor, cognitive, and imaging scores were correlated with each other in TRACK-HD participants, justifying use of a single, cross-domain measure of disease progression in both studies. The TRACK-HD and REGISTRY progression measures were correlated with each other (r=0·674), and with age at onset (TRACK-HD, r=0·315; REGISTRY, r=0·234). The meta-analysis of progression in TRACK-HD and REGISTRY gave a genome-wide significant signal (p=1·12 × 10−10) on chromosome 5 spanning three genes: MSH3, DHFR, and MTRNR2L2. The genes in this locus were associated with progression in TRACK-HD (MSH3 p=2·94 × 10−8 DHFR p=8·37 × 10−7 MTRNR2L2 p=2·15 × 10−9) and to a lesser extent in REGISTRY (MSH3 p=9·36 × 10−4 DHFR p=8·45 × 10−4 MTRNR2L2 p=1·20 × 10−3). The lead single nucleotide polymorphism (SNP) in TRACK-HD (rs557874766) was genome-wide significant in the meta-analysis (p=1·58 × 10−8), and encodes an aminoacid change (Pro67Ala) in MSH3. In TRACK-HD, each copy of the minor allele at this SNP was associated with a 0·4 units per year (95% CI 0·16–0·66) reduction in the rate of change of the Unified Huntington's Disease Rating Scale (UHDRS) Total Motor Score, and a reduction of 0·12 units per year (95% CI 0·06–0·18) in the rate of change of UHDRS Total Functional Capacity score. These associations remained significant after adjusting for age of onset. Interpretation The multidomain progression measure in TRACK-HD was associated with a functional variant that was genome-wide significant in our meta-analysis. The association in only 216 participants implies that the progression measure is a sensitive reflection of disease burden, that the effect size at this locus is large, or both. Knockout of Msh3 reduces somatic expansion in Huntington's disease mouse models, suggesting this mechanism as an area for future therapeutic investigation
