Objective: Skeletal dysplasias, cartilaginous or skeletal disorders that sometimes result in abnormal bone development, are seldom reported in free-ranging wild animals. Here, we use photogrammetry and comparative morphometric analyses to describe cases of abnormal appendicular skeletal proportions of free-ranging giraffe in two geographically distinct taxa: a Nubian giraffe (Giraffa camelopardalis camelopardalis) in Murchison Falls National Park, Uganda and an Angolan giraffe (Giraffa giraffa angolensis) on a private farm in central Namibia.
Results: These giraffe exhibited extremely shortened radius and metacarpal bones relative to other similarly aged giraffe. Both giraffe survived to at least subadult life stage. This report documents rare occurrences of these apparent skeletal dysplasias in free-ranging wild animals and the first records in giraffe.

Monitoring stress-related faecal glucocorticoid metabolite (fGCM) concentrations is a reliable, popular and established approach for understanding wildlife responses to perceived stressors. To maintain fGCM integrity post-defaecation, faecal material must be promptly stored frozen, or dried to prevent continued suspected bacterial enzyme activity. We compare the effectiveness of freeze-drying with other field-friendly drying techniques (food dehydrator and homemade solar oven).

Giraffe (Giraffa spp.) are among the most unique extant mammals in terms of anatomy, phylogeny, and ecology. However, aspects of their evolution, ontogeny, and taxonomy are unresolved, retaining lingering questions that are pivotal for their conservation.

This study employed high-throughput sequencing to explore bacterial diversity and hematological variations across different age groups of giraffes, as well as the impact of diarrhea on their intestinal microbiota. Additionally, the correlation between intestinal flora and hematological indices was examined for the first time. Firmicutes, Bacteroides, and Proteobacteria were the predominant bacterial groups in the giraffe's intestinal flora.

Purpose: To describe the advanced multimodal imaging findings of patients with bilateral diffuse uveal melanocytic proliferation (BDUMP) and the changes in these findings over time.
Methods: Fundus photography, fundus autofluorescence (FAF), fundus fluorescein angiography (FA), spectral domain optical coherence tomography (OCT), B-scan ultrasonography (US), and ultrasound biomicroscopy (UBM) images of the patients diagnosed with BDUMP at a single institution between years 2006-2023 were evaluated.
Results: Sixteen eyes of 8 patients with BDUMP were included.
