Operationalizing a fisheries social-ecological system through a Bayesian belief network reveals hotspots for its adaptive capacity in the southern North sea.

Fisheries social-ecological systems (SES) in the North Sea region confront multifaceted challenges stemming from environmental changes, offshore wind farm expansion, and marine protected area establishment. In this paper, we demonstrate the utility of a Bayesian Belief Network (BN) approach in comprehensively capturing and assessing the intricate spatial dynamics within the German plaice-related fisheries SES. The BN integrates ecological, economic, and socio-cultural factors to generate high-resolution maps of profitability and adaptive capacity potential (ACP) as prospective management targets. Our analysis of future scenarios, delineating changes in spatial constraints, economics, and socio-cultural aspects, identifies factors that will exert significant influence on this fisheries SES in the near future. These include the loss of fishing grounds due to the installation of offshore wind farms and marine protected areas, as well as reduced plaice landings due to climate change. The identified ACP hotspots hold the potential to guide the development of localized management strategies and sustainable planning efforts by highlighting the consequences of management decisions. Our findings emphasize the need to consider detailed spatial dynamics of fisheries SES within marine spatial planning (MSP) and illustrate how this information may assist decision-makers and practitioners in area prioritization. We, therefore, propose adopting the concept of fisheries SES within broader integrated management approaches to foster sustainable development of inherently dynamic SES in a rapidly evolving marine environment.

Socio-ecological vulnerability to tipping points: A review of empirical approaches and their use for marine management.

Sustainability in the provision of ecosystem services requires understanding of the vulnerability of social-ecological systems (SES) to tipping points (TPs). Assessing SES vulnerability to abrupt ecosystem state changes remains challenging, however, because frameworks do not operationally link ecological, socio-economic and cultural elements of the SES. We conducted a targeted literature review on empirical assessments of SES and TPs in the marine realm and their use in ecosystem-based management. Our results revealed a plurality of terminologies, definitions and concepts that hampers practical operationalisation of these concepts. Furthermore, we found a striking lack of socio-cultural aspects in SES vulnerability assessments, possibly because of a lack of involvement of stakeholders and interest groups. We propose guiding principles for assessing vulnerability to TPs that build on participative approaches and prioritise the connectivity between SES components by accounting for component linkages, cascading effects and feedback processes.

Osteotome sinus elevation and implant placement with narrow size bioactive glass.

A procedure using osteotomes and bioactive glass as an alloplastic bone graft material is discussed, and three clinical cases are reviewed. Bioactive glass of a narrow size range (300-355 microns) has been shown to be osteoconductive and allows for good integration and regeneration of surrounding bony tissue. We have found this technique to be a predictable method of preparing and placing longer implants in the region of the maxillary premolar region without the need for additional donor site morbidity.

Benign osteoblastoma of the jaws: report of three cases.

Three cases of benign osteoblastoma occurring in the jaws are presented along with radiographic and microscopic material. Pain was a consistent symptom reported in each case. It appears that there is no predilection for occurrence in either the mandible or maxilla.

Internal carotid pseudoaneurysm as a late complication of maxillofacial missile wound.

A delayed formation of a pseudoaneurysm of the internal carotid artery occurred secondary to a gunshot wound of the maxillofacial region. Its treatment concurrent with the treatment of a severely comminuted fracture of the mandible has been reported.
