Disputes over galago taxonomy have meant that studies often use ­different names for identical populations, making comparative analysis difficult for the untrained researcher. A main objective of this study was to assess whether hand and foot pad morphology, nail shape and toothscraper structure reveal adaptations to exudate eating and show differences which reflect taxonomy in order to identify species. A total of 714 museum specimens were examined between May and July 2007, revealing six pads… 
An investigation of ecological correlates with hand and foot morphology in callitrichid primates.
Comparisons of limb proportion and frictional features of the volar surfaces in preserved specimens of 25 callitrichid primates suggest that ridges on the soles and palms may facilitate food procurement by enhancing frictional grip during exudate feeding, and volar pad features corroborate taxonomic relationships described from dental morphology.
Searching for Dental Signals of Exudativory in Galagos
Dental morphometrics of galagos are assessed in an effort to search for a more complete dental signal of exudate-feeding in this group of marmosets and it is clear that other teeth, especially in combination, may provide a dental signal to exudates feeding in galagos.
Dental Signatures for Exudativory in Living Primates, with Comparisons to Other Gouging Mammals
It is suggested that reduction of mastication, and, therefore, M3 dimensions are a likely dental signature for exudativory in Primates.
Gummivory in Cheirogaleids: Primitive Retention or Adaptation to Hypervariable Environments?
A long-term field study of the reddish-grey mouse lemur, Microcebus griseorufus, in the highly variable xerophytic forest of southern Madagascar reveals this species to be the most specialized gummivore of all known mouse lemurs and a comparison of the nutritional composition of gums and fruits consumed shows these two food types to be of equivalent nutritive content.
Spatial and temporal ecological diversity amongst Eocene primates of France: evidence from teeth.
Diets of fossil taxa are assessed here by dental microwear analysis using a comparative database of 11 species of living strepsirhines to reveal the dietary range of this small-bodied omomyiform which seems to vary between insects and a much softer diet.
Postcranial indicators of primate sexual dimorphism: implications for reconstructing fossil hominin sexual dimorphism and hominin palaeoecology
The sustained accuracy of sex estimation through the best skeletal metric discriminators makes discriminant function analysis a practicable method of classifying sex for fossil hominin specimens.


The use of hand morphology in the taxonomy of galagos
Comparative studies of volar hand pad morphology provide a novel approach to the re-assessment of galago taxonomy, and may be applicable also in taxonomic studies of other prosimian groups.
A Biomechanical Analysis of Skull Form in Gum-Harvesting Galagids
It is found few consistent morphological patterns linking skull form and the generation of high forces during gouging and scraping are found, however, there is some tendency for gougers and scrapers to show increased load resistance capabilities in their mandibles.

Although toothcomb size variations among extant strepsirhines are more readily interpreted in terms of gum feeding and bark scraping than they are in Terms of grooming, anterior dental morphology as a whole is more easily explained by a grooming hypothesis when existing models of toothcomb origins are considered.
Intraspecific Variation in the Vocalizations and Hand Pad Morphology of Southern Lesser Bush Babies (Galago moholi): A Comparison with G. senegalensis
It is demonstrated that vocal and volar pad characteristics can be used as consistent measures of difference between species that look almost identical, and provide a practical means of distinguishing between cryptic species, whether in the field, in captivity, or, in the case of volar pads, of preserved specimens.
Acacia gum and its use by bushbabies,Galago senegalensis (Primates: Lorisidae)
Gums are available throughout the year and detailed records indicated no clearcut seasonal pattern of gum production, and they are therefore an important yearround food resource for the lesser bushbabies.
Three acoustic forms of Allen's galagos (Primates; Galagonidae) in the Central African region
The vocal data in this study provide evidence of at least three acoustic forms of galago within the Allen's group which are predicted to represent three distinct species.

The taxonomic status and distribution of Bushbabies in Malawi with emphasis on the significance of vocalizations
The debated identity of a small forest bushbaby in Malawi is resolved by a short-term field study of the animals’ behavior. Locomotor styles, calling patterns, and the structure of advertising calls
Synopsis ofGalago species characteristics
At the time of the symposium, “Variability Within the Galagos,” at the 1986 IPS Congress, most participants were still using Hill’s (1953) classification and nomenclature of galago species. All

It is suggested that the Malagasy lemurs and the Afro-Asian bush-babies and lorises had a common origin in Africa (lemur/loris stock), and that this ancestral stock had an earlier common origin with the Adapinae and Notharctinae of the Northern continents.
