A gestation length of 178 days was determined for Tarsius bancanus based on a vaginal smear containing whole sperm. This value replaces the only previously reported information on gestation length in tarsiers, a rough estimate of approximately 6 months for T. syrichta.

Hand-raising a philippine tarsier, Tarsius syrichta
TLDR
This is the first successful hand-raising of any species of tarsier, which is a genus that reproduces poorly in captivity.
Growth, development, and parental care in the western tarsier (Tarsius bancanus) in captivity: Evidence for a “slow” life-history and nonmonogamous mating system

    International Journal of Primatology

TLDR
The data suggest that there is an energetic/dietary basis for slow pre- and postnatal growth rates, but an extremely large neonatal brain size enables the rapid behavioral development and neuromuscular coordination necessary for this specialized predator to attain early nutritional independence.
Assessing female reproductive status of spectral tarsier (Tarsius tarsier) using fecal steroid hormone metabolite analysis
TLDR
The study demonstrates the overall validity of fecal sex hormone metabolite measurements for reproductive monitoring in female T. tarsier and validated fecal estrogen (E‐total) and progesterone metabolite (5‐P‐3OH) measurements for monitoring female ovarian activity and pregnancy.
Searching for the Haplorrhine Heterotherm: Field and Laboratory Data of Free-Ranging Tarsiers
TLDR
The potential for heterothermy in a primate closely related to the Strepsirrhini and the concern for the vulnerability of C. bancanus to future temperature increases associated with global warming are explored.

Temperature Regulation and Oxygen Consumption in the Philippine Tarsier Tarsius syrichta
TLDR
A tropical or subtropical distribution, small mass, insectivorous or Insectivorous-frugivorous diet, low basal rate, and low body temperature may represent the suite of characteristics found in the earliest primates.
Preliminary Observations of Infant Ontogeny in the Philippine Tarsier (Tarsius syrichta) and the First Description of Play Behaviour and Its Ontogeny in Tarsiers
TLDR
The first observations on the ontogeny of tarsier infants during their first and second months and of the mother-offspring bond from birth until separation are presented.
Social Behavior of a Reproducing Pair of the Philippine Tarsier (Tarsius syrichta) in Captivity
TLDR
The results present the first assessment of the social behavior of the Philippine tarsier, much needed to improve the captive breeding management for this highly sensitive species threatened with extinction.
Genomic data reject the hypothesis of a prosimian primate clade.
Life History Variation Among Nocturnal Prosimians
TLDR
Life histories are the key to understanding the action of natural selection because interactions among life history traits result in phenotypic adaptations that determine individual fitness through their direct effect on survival and reproduction.
