Based on existing map series of the North German Basin and their partial implementation into 3D models, a harmonized 3D-model of the North German Basin was developed in the project TUNB from 2014 onwards. The modelling work was conducted by the State Geological Surveys (SGD) of Schleswig-Holstein, Mecklenburg-Vorpommern, Brandenburg, Saxony-Anhalt, and Lower Saxony, as well as the Federal Institute for Geosciences and Natural Resources (BGR). The areas of the city-states of Hamburg, Bremen, and Berlin were modelled by the SGD of the neighbouring states. The German Exclusive Economic Zone (EEZ) of the North Sea, as well as parts of the Baltic Sea, were modelled by the BGR. After determination on the horizons to be modelled and the harmonization measures to be used by all parties, an initial test was run in a pilot region. Following this successful test, the entire model was created by the respective SGD and the BGR. The individual state models were handed over to the BGR, compiled there, and made available through a 3D web viewer application. In total, the model comprises 15 horizons, 5331 faults and 270 salt structures. It covers an area of approximately 167,500 km2, making it one of the largest 3D models in the world.

While thyroid disease is generally uncommon in rabbits and rodents, it is most frequently diagnosed in guinea pigs. Particularly, hyperthyroidism and thyroid neoplasms are diagnosed regularly in this species, while thyroid neoplasia is the most common thyroid disorder found in other rodents. Thyroid disease appears to be rare in rabbits, though modalities to reliably diagnose different disorders like hypothyroidism are currently lacking.

Limb fractures represent the most common orthopaedic disease in pet rabbits. However, only a few studies have evaluated therapeutic details of limb fractures. There are no data available for long‐term outcomes of limb fracture treatment. The medical records of six institutions were reviewed retrospectively to identify cases of traumatic limb bone fractures in pet rabbits between 1999 and 2020. The medical records (n= 387) were analysed for details of fracture prevalence, aetiology, therapy protocols, treatment complications, outcome and long‐term effects. In addition to the retrospective data evaluation, 13 rabbits were re‐evaluated in person in recent clinical analyses, including orthopaedic examination, radiography and computed‐tomographic imaging. Details of long‐term effects of fracture treatment were requested over the telephone for a further 232 animals using a standardised questionnaire. Long bone fractures accounted for the majority of all fractures (296/387; 76.5%). Hindlimb fractures (301/387; 77.7%) were more common than forelimb fractures (86/387; 22.2%), and tibial fractures and combined fractures of the tibia and fibula (119/387; 30.8%) were observed most frequently. Most fracture treatments were based on osteosynthesis procedures (243/328; 74.1%). Treatment complications occurred in 130 out of 328 (39.6%) cases. A high bodyweight (p= 0.047) and an older age (p= 0.01) were found to be significant risk factors for the emergence of therapy complications. Overall, 75.4% of animals (175/232) had a satisfactory long‐term outcome. Limb posture anomalies were evaluated in 61 cases (26.3%). The multi‐centre approach led to the inclusion of various institutions, veterinarians, treatment protocols and rabbit populations that might have influenced the results. The medical records were reviewed retrospectively, so there were some data that were lacking or could not be collected in a standardised manner. Furthermore, rabbit owners' evaluation of long‐term outcomes might be prone to error, despite the use of a standardised interview questionnaire. Limb fractures are a common orthopaedic issue in pet rabbits. The patient's bodyweight and age are significant risk factors for the emergence of complications during the fracture treatment process. Long‐term orthopaedic effects, such as abnormal limb posture and permanent lameness of the affected limb, were observed regularly.
