RESUMO

The ongoing COVID-19 pandemic affects people worldwide. The policies in response to the virus range from closure of national borders to curfews for entire metropolises, like Paris. While we can expect severe impacts on the world economy, the consequences of the pandemic for local sustainability transitions are entirely unclear. In this exploratory study, we investigate how the current situation affects the work of transition intermediaries in the energy sector. More concretely, we aim to analyse the impact of COVID-19 policies on community energy projects and the subsequent change of work practices of intermediaries in this situation. Our data consists of qualitative data we collected between January and October 2020. Our results show that transition intermediaries are affected in different ways. Most notably, the work on networking suffers during these times of crisis. We found that intermediaries are particularly challenged in their ability to build trust. This particularly affects new and complex community energy projects and intermediation activities needed for systemic change. We found that established projects with a strong trust base are least affected by these limitations. Intermediaries dependent on private funding face much bigger problems than publically funded organisations. Our results offer some novel and relevant insights in the role and work of transition intermediaries and the development of community energy projects in times of crisis. These findings can help governments, intermediary organizations and citizen groups to design future transition processes in ways that are more resilient to external shocks.

RESUMO

The use of environmental DNA (eDNA) has become an applicable noninvasive tool with which to obtain information about biodiversity. A subdiscipline of eDNA is iDNA (invertebrate-derived DNA), where genetic material ingested by invertebrates is used to characterize the biodiversity of the species that served as hosts. While promising, these techniques are still in their infancy, as they have only been explored on limited numbers of samples from only a single or a few different locations. In this study, we investigate the suitability of iDNA extracted from more than 3,000 haematophagous terrestrial leeches as a tool for detecting a wide range of terrestrial vertebrates across five different geographical regions on three different continents. These regions cover almost the full geographical range of haematophagous terrestrial leeches, thus representing all parts of the world where this method might apply. We identify host taxa through metabarcoding coupled with high-throughput sequencing on Illumina and IonTorrent sequencing platforms to decrease economic costs and workload and thereby make the approach attractive for practitioners in conservation management. We identified hosts in four different taxonomic vertebrate classes: mammals, birds, reptiles and amphibians, belonging to at least 42 different taxonomic families. We find that vertebrate blood ingested by haematophagous terrestrial leeches throughout their distribution is a viable source of DNA with which to examine a wide range of vertebrates. Thus, this study provides encouraging support for the potential of haematophagous terrestrial leeches as a tool for detecting and monitoring terrestrial vertebrate biodiversity.

RESUMO

We present a rare case of a 3-year-old boy with an odontogenic myxoma (OM) involving the orbita. Including our case, only nine cases of OM have been reported to involve the eye in children.There is no gold standard for treatment of OM in children with orbital involvement. The recurrence rate of OM in children seems low, which advocates for less invasive surgery. A gentle resection of the OM was carried out. The floor and medial wall of the orbit was reconstructed immediately using a non-resorbable Medpor implant with passive adaptation. Reconstruction with a Medpor implant in children has rarely been reported in the literature. No clinical or radiological recurrence was observed 24 months after surgical removal, and the patient presented with symmetric appearance and normal vision.
