Altitude influences forest structure and food abundance and distribution, which in turn affect primate feeding and ranging patterns. Javan gibbons (Hylobates moloch) are endemic to forests spanning a broad range of altitudes on Java, Indonesia. Most ... |
The Effects Of Lactation And Infant Care On Adult Energy Budgets In Wild Siamangs (Symphalangus syndactylus) |
2009 |
1305 |
In mammals with biparental care of offspring, males and females may bear substantial energetic costs of reproduction. Adult strategies to reduce energetic stress include changes in activity patterns, reduced basal metabolic rates, and storage of ener... |
Evolution In The Symbolic Dimension: The Devil Is In The Details |
2007 |
649 |
Evolution in Four Dimensions argues convincingly that non-genetic inheritance systems have the potential to be agents of evolution and that, in some circumstances, acquired information can be heritable. However, we found the authors' four-dimensional... |
Female Songs Of The Nonduetting Javan Gibbons (Hylobates moloch) Function For Territorial Defense |
2017 |
189 |
Duets in territorial, pair-living primates may function to maintain intragroup cohesion, promote intergroup avoidance, and assist in territorial and resource defense, as well as advertising and reinforcing pair bonds. Despite the absence of duetting ... |
Flowers Are An Important Food For Small Apes In Southern Sumatra |
2009 |
1054 |
Flowers are included in the diets of many primates, but are not generally regarded as making an important contribution to primate energy budgets. However, observations of a number of lemur, platyrrhine, and cercopithecine populations suggest that som... |
The Human-Primate Interface In The New Normal: Challenges And Opportunities For Primatologists In The COVID-19 Era And Beyond |
2020 |
1407 |
The emergence of SARS-CoV-2 in late 2019 and human responses to the resulting COVID-19 pandemic in early 2020 have rapidly changed many aspects of human behavior, including our interactions with wildlife. In this commentary, we identify challenges an... |

As a group of primatologists work towards protecting Malaysia’s small apes, here’s how MNS members and the public can help. |
Long-Term Effects Of Forest Fire On Habitat Use By Siamangs In Southern Sumatra |
2020 |
1108 |
Forest fires can cause direct mortality to wildlife, and the associated habitat damage can reduce carrying capacity and population densities. However, little is known about long-term responses of animals to fire in the wet tropics. From 2000-2015, we... |
Male Care Of Infants In A Siamang (Symphalangus syndactylus) Population Including Socially Monogamous And Polyandrous Groups |
2008 |
2053 |
While male parental care is uncommon in mammals, siamang (Symphalangus syndactylus) males provide care for infants in the form of infant carrying. I collected behavioral data from a cohort of five wild siamang infants from early infancy until age 15–... |
Mating In The Presence Of A Competitor: Audience Effects May Promote Male Social Tolerance In Polyandrous Siamang (Symphalangus syndactylus) Groups |
2014 |
990 |
Audience effects on sexual behavior, including changes in copulation frequency and duration in the presence of conspecifics, have been reported in multimale – multifemale groups of several primate species. We examined the interaction of male sexual b... |
Patterns Of Dispersal In Sumatran Siamangs (Symphalangus syndactylus): Preliminary mtDNA Evidence Suggests More Frequent Male Than Female Dispersal To Adjacent Groups |
2006 |
1062 |
Gibbons of both sexes have been observed emigrating from their natal groups, but the consequences of dispersal in gibbons are poorly understood, and it is unclear whether these are the same for both sexes. I sequenced a 350-bp fragment of mitochondri... |
