Positional behavior and social organization of the philippine tarsier (Tarsius syrichta)

  title={Positional behavior and social organization of the philippine tarsier (Tarsius syrichta)},
  author={Marian Dagosto and Daniel Lee Gebo and Cynthia Dolino},
This study provides preliminary data on the positional behavior and habitat use of the Philippine tarsier,Tarsius syrichta, which was studied in its natural habitat on the island of Leyte. The locomotor behavior ofT. syrichta is quite comparable to the other species of tarsiers but frequency of use of different postures and support types does seem to distinguish this species from the others.Tarsius bancanus appears to be the most specialized, using vertical clinging postures the most frequently… 

Activity Patterns of Captive Philippine Tarsiers (Tarsius syrichta): Differences Related to Sex and Social Context

It is found that the sexes do not differ in activity budgets during the non-mating season, both spending most of their time scanning, resting, foraging and travelling, and although both tarsiers noticeably increased travelling time at the expense of time spent resting, the male changed his behaviour to a much greater extent than the female.

Preliminary Data on the Behavior, Ecology, and Morphology of Pygmy Tarsiers (Tarsius pumilus)

The first behavioral, morphological, and ecological data on a living group of highland pygmy tarsiers, Tarsius pumilus, are presented and the importance of altitudinal ecological gradients to tarsier behavioral ecology in Central Sulawesi is identified, providing questions and predictions for future research directions.

Social Behavior of a Reproducing Pair of the Philippine Tarsier (Tarsius syrichta) in Captivity

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.

Successful breeding attempt of a pair of Philippine tarsier (Tarsius syrichta) in a conservation center in Bilar, Bohol, Philippines and recommendations for tarsier husbandry.

This paper presents an example of successful breeding of the Philippine tarsier in captive conditions but in natural climate and shows a large amount of space provided to tarsiers, the climate similar to their natural habitat and the food resembling their natural diet.

Acoustic Repertoire of the Philippine Tarsier (Tarsius syrichta fraterculus) and Individual Variation of Long-Distance Calls

This study provides the first evidence of individual variation in the long-distance calls performed by tarsiers, and provides a basis for future comparison within as well as between tarsier species taxonomy.

Vertical Clinging and Leaping Revisited: Locomotion and Habitat Use in the Western Tarsier, Tarsius bancanus Explored Via Loglinear Modeling

It is shown that climbing, as well as leaping, is one of the predominant forms of locomotion, and that all other things being equal, tarsiers tend to take off from, and land on, similar sized supports, which suggests that the following findings are not likely to be a result of substrate availability alone.

Living in small spaces: Forest fragment characterization and its use by Philippine tarsiers (Tarsius syrichta Linnaeus, 1758) in Mindanao Island, Philippines

The Philippine tarsier (Tarsius syrichta) is a charismatic species that is threatened by illegal hunting and deforestation. Although they occur in forest and disturbed habitats, ecological

Tarsier talk : Tarsiers, hunters, and ecotourism in Corella, bohol

In 1997, the Philippine tarsier (Tarsius syrichta) was declared a “specially protected faunal species of the Philippines” through Proclamation 1030 released by the President Ramos administration. The

Preliminary Observations of Infant Ontogeny in the Philippine Tarsier (Tarsius syrichta) and the First Description of Play Behaviour and Its Ontogeny in Tarsiers

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.



Ranging, activity rhythms, and sociality in free-rangingTarsius bancanus: A preliminary report

The present evidence suggests that the social organization of western tarsiers resembles that of Lorisinae and some Galaginae, but with much less direct or close contact, and does not tend to support arguments for the existence of monogamy or pair bonding in this species.

The spectral tarsier is gregarious during its nightly activity period as well as in its sleeping tree, as shown by focal follows conducted at Tangkoko Nature Reserve in Sulawesi, Indonesia.

The behavior of wild spectral tarsiers

Although clearly specialized for vertical clinging and leaping, the spectral tarsiers is less specialized than the western tarsier, occupying a wider range of habitats and using a widerrange of vegetation strata and locomotor patterns.

Space and substrate use in captive western tarsiers,Tarsius bancanus

It is found that captive T. bancanus uses space in a distinctly nonrandom manner, exhibiting a preference for midlevel heights and upright, small-diameter substrates.

Locomotion and habitat utilization in free-rangingTarsius bancanus: A preliminary report

It is suggested that the energetic constraints of small body size together with the need to patrol large home ranges may have lead both to Tarsius bancanus extreme degree of locomotor specialization and to its exclusive animalivory.

The identity of Tarsius pumilus, a pygmy species endemic to the montane mossy forests of central Sulawesi. American Museum novitates ; no. 2867

In 1917, Henry C. Raven obtained a small-bodied tarsier from upper montane rain forest in the mountains of Central Sulawesi. Miller and Hollister (192 lb) designated the specimen as holotype of

Habitat use, foraging behavior, and activity patterns in reproducing western tarsiers, Tarsius bancanus, in captivity: A managment synthesis

Empirical and experimental results from a 5-year study of behavior and life history in captive Tarsius bancanus show that Chase/displacement rates increased significantly during late pregnancy and lactation, apparently in an attempt to keep males from harassing infants.

The distribution and ecology of mammals on Leyte, Biliran and Maripipi Islands, Philippines /

Data indicate that the present-day mammal faunas of these islands have been shaped primarily by events that occurred during the last 12,000 years, and indicates that disturbances to natural habitat have a disproportionately greater negative impact on the unique endemic portions of a local fauna.

The results suggest that subadults may be guarding or babysitting infants, and it is also possible thatSubadults are not traveling as far from the sleeping site as adults do and are therefore more likely to be found in association with the infant.
