An Examination of the Function of Urine Washing in Galago senegalensis
TLDR
Data from the present study and others indicated that urine washing did not function as an olfactory sign marking territorial boundaries, and it was suggested that in this species it facilitated grip.Abstract:
A wild, female Galago senegalensis molohi (lesser bushbaby) was radio collared and followed for 139 h. The occurrence of ‘urine washing’, wetting the hands and feet with urine, was recorded and analysed in terms of when and where it took place and with what other behaviours it was associated. Data from the present study and others indicated that urine washing did not function as an olfactory sign marking territorial boundaries. It was suggested that in this species it facilitated grip.read more

Animal tool use: current definitions and an updated comprehensive catalog
Vicki K. Bentley-Condit,Smith +1 more
TL;DR: An updated, comprehensive catalog of documented animal tool use is presented that indicates whether the behaviours observed included any 'true' tool use, whether the observations were limited to captive animals, whether tool manufacture has been observed, and whether the observed tool use was limited to only one individual and, thus, 'anecdotal' (i.e., N = 1).

The nocturnal primate niche in the New World
TL;DR: Comparisons suggest that convergences between the monkey with a diurnal ancestor and the prosimians with nocturnal ancestors exist, but Aotus is intermediate between prosimian and diurnal monkeys in visual acuity in low light levels, color vision, and olfactory capabilities.

A Re-Evaluation of the Role of Vision in the Activity and Communication of Nocturnal Primates
TL;DR: It is suggested that the light and dark facial markings of many species convey information about species and individual identity when animals approach each other at night, and differences in the colour of the reflective eye-shine, and behavioural responses displayed when exposed to white torchlight point to different kinds of nocturnal vision that are suited to each niche.

Adaptive origins of primates revisited.
TL;DR: It is shown that neither the fossil record nor modern species provide evidence that the last common ancestor of living primates was small, and comparative weight distributions of arboreal mammals and a phylogenetic reconstruction of ancestral primate body mass indicate that the reduction of functional claws to nails resulted from an increase in body mass to around 1000 g or more in the primate stem lineage.

Urine marking and territoriality in Galago alleni (Waterhouse, 1837--Lorisoidea, Primates)--a field study by radio-telemetry.
TL;DR: The function of urine washing is interpreted as a means of dispersal of urine marks (social signals) in a three-dimensional milieu where displacement by a combination of leaping and running creates numerous pathways.

TL;DR: An interpretation has been made of more than 120 interactions observed in the field based on the behaviour of bushbabies introduced to one another under controlled semi-natural conditions.

Olfactory marking of territory in two young male loris, Loris tardigradus lydekkerianus, kept in captivity in Poona
D.R. Ilse,K. Raschke +1 more
TL;DR: Two types of stereotyped behaviour involving micturition, have been observed in two immature males of Loris tardigradus from Bangalore, kept in captivity in a room in Poona, provisionally interpreted as “olfactory marking of territory” and “urine washing” respectively.

Response To Novel Objects in Three Lower Primates : Greater Galago, Slow Loris, and Owl Monkey
TL;DR: Greater galago, slow loris, and owl monkey were measured as response to novel objects; animals could choose between remaining on the familiar, home cage side or entering the novel side which contained six manipulable objects.
