In arboreal habitats gaps between branches and branch structure profoundly affect the ability of animals to move; hence, an ability to perceive such attributes could facilitate choosing routes that enhance the speed and ease of locomotion. Although many snakes are arboreal, no previous study has determined whether they can perceive structural variation of branches that is mechanically relevant to their locomotion. We tested whether the gap distance, location, and attributes of two destination… 
The effects of three-dimensional gap orientation on bridging performance and behavior of brown tree snakes (Boiga irregularis)
TLDR
The results suggest that failure due to the inability to keep the body rigid at the edge of the gap may be the primary constraint on performance for gaps with a large horizontal component.
Arboreal habitat structure affects locomotor speed and perch choice of white-footed mice (Peromyscus leucopus).
TLDR
For a given diameter, the speeds of mice were usually faster when running horizontally rather than running uphill or downhill, and the presence of pegs greatly decreased running speed compared to unobstructed surfaces, but the magnitude of this effect decreased as diameter increased.
Scale-dependent orientation in movement paths: a case study of an African viper
Decisions relating to the orientation of movement by animals and how this translates into movement patterns can occur at multiple spatial scales simultaneously, but this interaction is poorly

TLDR
Focusing on the biomechanics of these behaviors, broad categorizations that facilitate comparisons between taxa are suggested, and the importance of gap distance in determining crossing behavior is discussed.
Perch diameter and branching patterns have interactive effects on the locomotion and path choice of anole lizards
TLDR
It is suggested that preferring larger diameters in natural vegetation has a direct benefit for speed and an added benefit of allowing detouring around branches with little adverse effect on speed.
Three-dimensional locations of destinations have species-dependent effects on the choice of paths and the gap-bridging performance of arboreal snakes.

TLDR
Despite quite uniform effects of gap location on bridging abilities and torques acting on the animals, some preferences for locations were species specific.
Tiger Salamanders (Ambystoma tigrinum) Increase Foot Contact Surface Area on Challenging Substrates During Terrestrial Locomotion
TLDR
It is concluded that salamanders modulate the use of their feet depending on the substrate, particularly on DS which is known to increase the mechanical work and energy expended during locomotion owing to the fluid nature of its loose particles.

TLDR
Pegs considerably enhanced the locomotor performance of snakes, although similar structures such as secondary branches seem likely to impede the locomotion of limbed arboreal animals.
RESOURCE USE IN ARBOREAL HABITATS: STRUCTURE AFFECTS LOCOMOTION OF FOUR ECOMORPHS OF ANOLIS LIZARDS
Previous laboratory studies have frequently determined the maximal running speeds of lizards. However, neither the extent to which animals use maximal speeds in nature nor the effects of arboreal
Scaling of the axial morphology and gap-bridging ability of the brown tree snake, Boiga irregularis
TLDR
An estimate of the muscle strain required to prevent the body of the snake from buckling suggests that, despite being light-bodied, brown tree snakes bridging a gap may be at the limit of the physiological capacity of their epaxial muscles.
Effects of perch diameter and incline on the kinematics, performance and modes of arboreal locomotion of corn snakes (Elaphe guttata)
TLDR
The numerous effects of perch diameter on kinematics and the similarity to tunnel concertina locomotion emphasize the importance of fit as a limitation in arboreal locomotion of snakes, however, the slower speeds on horizontal perches compared to tunnels also suggest that balance and grip may further limit locomotor performance.
Life-history adaptations to arboreality in snakes.
TLDR
Comparative (phylogenetically based) analysis of data from 12 pythonid and 12 boid snake species reveals multiple evolutionary shifts in habitat use, notably in the evolution of arboreal habits.
Barking up the wrong tree: climbing performance of rat snakes and its implications for depredation of avian nests
TLDR
To determine if variation in bark-surface irregularities may influence the ability of a predator species to access the contents of avian nests, the climbing abilities of rat snakes (Elaphe obsoleta) on trees having three different bark types were examined.

TLDR
It is suggested that such small, non-dimorphic species are best suited for insinuation into complex faunas, whereas larger, dimorphic forms are best for the colonization of empty areas.
Scanning and route selection in the jumping spider Portia labiata
TLDR
Jumping spiders Portia labiata were tested in the laboratory on three different kinds of detours, and two rules seemed to govern their scanning: they would continue turning in one direction when scanning away from the lure along horizontal features of the detour route and change direction when the end of the horizontal feature being scanned was reached.
