Peer-reviewed research on arboreal locomotion, positional behaviour, and ecology, from a decade studying primates and other mammals in the field and in the lab.
The most recent of two studies on Acacia rats, integrating substrate size, inclination, and availability with locomotor and postural behaviour in a captive colony.
The first quantitative study of locomotion and posture in the southern pygmy slow loris, in the wild or captivity, gathering evidence to guide conservation and reintroduction planning.
The first GPS-telemetry study of European wildcat spatial ecology and diel activity in Greece and the Balkans, using five collared animals in a wetland-agricultural landscape.
An experimental study of vertical climbing in one of the world's smallest rodents, the Eurasian harvest mouse, measuring how it adjusts its gaits climbing up and down branches of different diameters, and what this reveals about how the earliest tiny eutherian mammals may have negotiated the arboreal world.
The first quantitative study of positional behavior in Linnaeus's two-toed sloth, combining naturalistic observation with kinematic and kinetic data from a simulated arboreal runway to test whether sloths behave as passive linked struts while hanging and walking below branches.
A captive study of the marsupial feathertail glider Acrobates pygmaeus, testing whether a versatile positional repertoire, preference for fine substrates, and hallucal grasping in this tiny arboreal marsupial can model a plausible stage in early euprimate locomotor evolution.
The first study of locomotion in the acacia rat, examining how this small arboreal African rodent adjusts its gaits and gait metrics to substrate size and inclination on simulated branches, and how those adjustments support its life in Acacia tree canopies.
A first quantitative comparison of arboreal gaits on simulated substrates of different diameters in two sympatric dormice of very different body size, the hazel dormouse and the edible dormouse, testing whether gait choice and velocity regulation scale with body mass.
At about 10 g, the Eurasian harvest mouse is among the smallest rodents — so how does it walk along a branch? Measuring gait metrics on poles of four diameters and three inclinations, this study finds harvest mice use slow, cautious lateral-sequence walks that grow faster and more diagonal on wider supports, and argues that gait metrics, unlike velocity, are largely independent of body size.
Comparing gait metrics of a burrowing mouse, a scansorial vole, and a more arboreal mouse on substrates of different size and incline, to test whether arboreal competence tracks each species' ecology.
Filming wild-caught northern smooth-tailed treeshrews in Vietnam to analyze how their foot mechanisms shift with substrate size and inclination, and what that reveals about the early evolution of pedal grasping in euarchontan mammals.
The feathertail glider — at 12 g, one of the smallest gliding marsupials — turns out to walk like a primate. This study of 18 gliders on poles of varying diameter and inclination shows they preferentially use diagonal-sequence gaits, and argues that such small-bodied grasping arborealists are a compelling behavioural model for the earliest primates.
