Injuries from leopard attacks in Kashmir

Lethal combats in the forest among wild western gorillas

Lethal intergroup encounters occur in many species because of sexual selection. While documented in mountain gorillas, they are absent in western gorillas as, instead, it is predicted by their higher feeding (frugivory) and mate competition (single-vs. multi-male groups). We investigate whether the injuries on three dead silverbacks and one adult female from four groups of western gorillas in the Central African Republic, resulted from interactions with gorillas or leopards. We identified two distinct injury patterns caused by gorillas (isolated lacerations, round wounds) and leopards (punctures clustered on head/neck) by analyzing injuries caused by mountain gorillas and leopards to gorillas and non-gorilla species, respectively. The western gorilla injury pattern is similar to that of mountain gorillas suggesting that lethal encounters occur, albeit infrequently, as predicted by sexual selection in a one-male society. While sexual dimorphism and polygynous sociality favored the evolution of violent encounters, multiple males in groups may influence their frequency.

Traumatic injury patterns in humans from large feline predators: A systematic review and descriptive analysis

Background

Traumatic attacks from large feline predators cause a small yet significant burden of disease in rural populations, are increasing in frequency, cause complex injuries and worsen human–wildlife conflicts. Data on the traumatic injury pattern found in victims of these animals is sparse, and this study aimed to collate and synthesise patterns of injury to inform the care and management of these patients.

Methods

A multi-ethnographic literature search (PubMed, Embase, Web of Science, Google Scholar, and other sources) was performed on 12/1/21 to capture all available data describing anatomical injury and the mechanism of injury sustained by humans from attacks by lions, leopards and tigers. Quality and bias assessment was performed using the Joanna Briggs Critical Evaluation tools.

Results

Of 5110 studies identified, 42 were included in this review totalling 84 individual patient cases. A total of 85% of fatal injuries were due to exsanguination combined with neuroaxis injury of the neck. All wounds were susceptible to tissue loss, infection and long-term neuro-vascular complications. Leopards injured anterior-midline structures of the neck more often than did lions and tigers, while the latter caused high-energy fractures. Time lag to treatment for survivors of wild attacks extended to multiple days, and occult injury was common.

Conclusion

In addition to the primary finding of complex neck injury, this study generated specific patterns of injury seen from the included species and highlighted occult injury and healthcare disparity as challenges in providing patient care.
