A horse's locomotor signature : COP path determined by the individual limb Universiteit Gent Koninklijke Maatschappij voor Dierkunde van Antwerpen Universiteit Antwerpen
Introduction : Ground reaction forces in sound horses with asymmetric hooves show systematic differences in the horizontal braking force and relative timing of break-over. The Center Of Pressure (COP) path quantifies the dynamic load distribution under the hoof in a moving horse. The objective was to test whether anatomical asymmetry, quantified by the difference in dorsal wall angle between the left and right forelimbs, correlates with ...
Interspecific variation in the tetradactyl manus of modern tapirs (**Perissodactyla: Tapirus**) exposed using geometric morphometrics Universiteit Antwerpen Koninklijke Maatschappij voor Dierkunde van Antwerpen
The distal forelimb (autopodium) of quadrupedal mammals is a key morphological unit involved in locomotion, body support, and interaction with the substrate. The manus of the tapir (Perissodactyla: Tapirus) is unique within modern perissodactyls, as it retains the plesiomorphic tetradactyl (four-toed) condition also exhibited by basal equids and rhinoceroses. Tapirs are known to exhibit anatomical mesaxonic symmetry in the manus, although ...

Lethal aggression in Pan is better explained by adaptive strategies than human impacts Koninklijke Maatschappij voor Dierkunde van Antwerpen
Observations of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) provide valuable comparative data for understanding the significance of conspecific killing. Two kinds of hypothesis have been proposed. Lethal violence is sometimes concluded to be the result of adaptive strategies, such that killers ultimately gain fitness benefits by increasing their access to resources such as food or mates(1-5). Alternatively, it could be a ...
Prevalence of Devriesea agamarum in the lizard collection of The Royal Zoological Society of Antwerp Koninklijke Maatschappij voor Dierkunde van Antwerpen
In recent times, Devriesea agamarum has been diagnosed more frequently as the causative organism of dermatitis in lizards, particularly in spiny-tailed lizards (Uromastyx sp.). Other lizard species such as bearded dragons (Pogona vitticeps) are known to be asymptomatic carriers, posing a potential threat
to the healthy animals in a collection. This study reports on the isolation and phenotypic identification of D. agamarum from six healthy ...

Age-related changes in urinary testosterone levels suggest differences in puberty onset and divergent life history strategies in bonobos and chimpanzees Koninklijke Maatschappij voor Dierkunde van Antwerpen
Research on age-related changes in morphology, social behavior, and cognition suggests that the development of bonobos (Pan paniscus) is delayed in comparison to chimpanzees (Pan troglodytes). However, there is also evidence for earlier reproductive maturation in bonobos. Since developmental changes such as reproductive maturation are induced by a number of endocrine processes, changes in hormone levels are indicators of different developmental ...
Insect prey characteristics affecting regional variation in chimpanzee tool use Koninklijke Maatschappij voor Dierkunde van Antwerpen
It is an ongoing interdisciplinary pursuit to identify the factors shaping the emergence and maintenance of tool technology. Field studies of several primate taxa have shown that tool using behaviors vary within and between populations. While similarity in tools over spatial and temporal scales may be the product of socially learned skills, it may also reflect adoption of convergent strategies that are tailored to specific prey features. Much ...
Dispersal and predation of diaspores of Coula edulis Baill. in an evergreen forest of Gabon Koninklijke Maatschappij voor Dierkunde van Antwerpen
The African walnut (Coula edulis) is a tree species of African evergreen forests, the seeds of which are collected and traded by African people. Many animal species consume African walnut diaspores; however, their roles as dispersers or predators have yet to be clarified. In this study, we present observations conducted in two different habitats of a Gabonese region over a 3-year period. The originality of this research resides in the ...
