The carnivore mandible as a lower part of the facial skeleton has a unique morphological characteristic and importance for the taxonomy. This study aimed to investigate size and shape differences of the mandible of the red fox and golden jackal. The research included 17 adult red fox and golden jackal mandibles from B&H. The morphometric analysis was performed on the 11 measurements and geometric analysis evaluates shape variation between two species with ten landmarks. The study revealed that the mandible of the jackal was longer and of massive bone compared to fox mandibles. The most significant difference was the total length, the indentation between the condylar and the angular process, and the measurement from the aboral alveolus of the canine tooth to the condylar process. The molar teeth parameters show similar values, especially the carnassial teeth. PC1 and PC2, which account for the highest variation, account for 68.8% of the total variation. The present study provided morphometric and geometric data on red fox and golden jackal mandibles, which can be a significant resource in the taxonomy of carnivores.
Spondyloarthropathy in a captive female brown bear (Ursus arctos) ABSTRACT Spondyloarthropathy is a form of arthritis that affects spine, especially sacroiliac joint leading to the severe, chronic pain and over time, can cause complete fusion of the sacroiliac (SI) joint. The present report describes a case of spondyloarthropathy in a captive female brown bear (Ursus arctos) from Sarajevo zoo, Bosnia and Herzegovina. Morphological inspection and radiograph of the macerated sacral and coxal bone specimen was performed. Both examinations showed complete bilateral symmetrical fusion of the sacral and coxal bone with syndesmophyte formation. Animals residing in zoos are kept under specific conditions which lead to inactivity and possible mobility problems caused by some sort of spondyloarthropathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
