Body Measurements for the Monkeys of Bioko Island, Equatorial Guinea
Primate Conservation 2009 (24): 99–105 Body Measurements for the Monkeys of Bioko Island, Equatorial Guinea Thomas M. Butynski¹,², Yvonne A. de Jong² and Gail W. Hearn¹ ¹Bioko Biodiversity Protection Program, Drexel University, Philadelphia, PA, USA ²Eastern Africa Primate Diversity and Conservation Program, Nanyuki, Kenya Abstract: Bioko Island, Equatorial Guinea, has a rich (eight genera, 11 species), unique (seven endemic subspecies), and threat- ened (five species) primate fauna, but the taxonomic status of most forms is not clear. This uncertainty is a serious problem for the setting of priorities for the conservation of Bioko’s (and the region’s) primates. Some of the questions related to the taxonomic status of Bioko’s primates can be resolved through the statistical comparison of data on their body measurements with those of their counterparts on the African mainland. Data for such comparisons are, however, lacking. This note presents the first large set of body measurement data for each of the seven species of monkeys endemic to Bioko; means, ranges, standard deviations and sample sizes for seven body measurements. These 49 data sets derive from 544 fresh adult specimens (235 adult males and 309 adult females) collected by shotgun hunters for sale in the bushmeat market in Malabo. Key Words: Bioko Island, body measurements, conservation, monkeys, morphology, taxonomy Introduction gordonorum), and surprisingly few such data exist even for some of the more widespread species (for example, Allen’s Comparing external body measurements for adult indi- swamp monkey Allenopithecus nigroviridis, northern tala- viduals from different sites has long been used as a tool for poin monkey Miopithecus ogouensis, and grivet Chlorocebus describing populations, subspecies, and species of animals aethiops). -

Primates of the Southern Mentawai Islands
Primate Conservation 2018 (32): 193-203 The Status of Primates in the Southern Mentawai Islands, Indonesia Ahmad Yanuar1 and Jatna Supriatna2 1Department of Biology and Post-graduate Program in Biology Conservation, Tropical Biodiversity Conservation Center- Universitas Nasional, Jl. RM. Harsono, Jakarta, Indonesia 2Department of Biology, FMIPA and Research Center for Climate Change, University of Indonesia, Depok, Indonesia Abstract: Populations of the primates native to the Mentawai Islands—Kloss’ gibbon Hylobates klossii, the Mentawai langur Presbytis potenziani, the Mentawai pig-tailed macaque Macaca pagensis, and the snub-nosed pig-tailed monkey Simias con- color—persist in disturbed and undisturbed forests and forest patches in Sipora, North Pagai and South Pagai. We used the line-transect method to survey primates in Sipora and the Pagai Islands and estimate their population densities. We walked 157.5 km and 185.6 km of line transects on Sipora and on the Pagai Islands, respectively, and obtained 93 sightings on Sipora and 109 sightings on the Pagai Islands. On Sipora, we estimated population densities for H. klossii, P. potenziani, and S. concolor in an area of 9.5 km², and M. pagensis in an area of 12.6 km². On the Pagai Islands, we estimated the population densities of the four primates in an area of 11.1 km². Simias concolor was found to have the lowest group densities on Sipora, whilst P. potenziani had the highest group densities. On the Pagai Islands, H. klossii was the least abundant and M. pagensis had the highest group densities. Primate populations, notably of the snub-nosed pig-tailed monkey and Kloss’ gibbon, are reduced and threatened on the southern Mentawai Islands. -
Diets of Howler Monkeys
Chapter 2 Diets of Howler Monkeys Pedro Américo D. Dias and Ariadna Rangel-Negrín Abstract Based on a bibliographical review, we examined the diets of howler mon- keys to compile a comprehensive overview of their food resources and document dietary diversity. Additionally, we analyzed the effects of rainfall, group size, and forest size on dietary variation. Howlers eat nearly all available plant parts in their habitats. Time dedicated to the consumption of different food types varies among species and populations, such that feeding behavior can range from high folivory to high frugivory. Overall, howlers were found to use at least 1,165 plant species, belonging to 479 genera and 111 families as food sources. Similarity in the use of plant taxa as food sources (assessed with the Jaccard index) is higher within than between howler species, although variation in similarity is higher within species. Rainfall patterns, group size, and forest size affect several dimensions of the dietary habits of howlers, such that, for instance, the degree of frugivory increases with increased rainfall and habitat size, but decreases with increasing group size in groups that live in more productive habitats. Moreover, the range of variation in dietary habits correlates positively with variation in rainfall, suggesting that some howler species are habitat generalists and have more variable diets, whereas others are habi- tat specialists and tend to concentrate their diets on certain plant parts. Our results highlight the high degree of dietary fl exibility demonstrated by the genus Alouatta and provide new insights for future research on howler foraging strategies. Resumen Con base en una revisión bibliográfi ca, examinamos las dietas de los monos aulladores para describir exhaustivamente sus recursos alimenticios y la diversidad de su dieta. -

Colobus Angolensis Palliatus) in an East African Coastal Forest
African Primates 7 (2): 203-210 (2012) Activity Budgets of Peters’ Angola Black-and-White Colobus (Colobus angolensis palliatus) in an East African Coastal Forest Zeno Wijtten1, Emma Hankinson1, Timothy Pellissier2, Matthew Nuttall1 & Richard Lemarkat3 1Global Vision International (GVI) Kenya 2University of Winnipeg, Winnipeg, Canada 3Kenyan Wildlife Services (KWS), Kenya Abstract: Activity budgets of primates are commonly associated with strategies of energy conservation and are affected by a range of variables. In order to establish a solid basis for studies of colobine monkey food preference, food availability, group size, competition and movement, and also to aid conservation efforts, we studied activity of individuals from social groups of Colobus angolensis palliatus in a coastal forest patch in southeastern Kenya. Our observations (N = 461 hours) were conducted year-round, over a period of three years. In our Colobus angolensis palliatus study population, there was a relatively low mean group size of 5.6 ± SD 2.7. Resting, feeding, moving and socializing took up 64%, 22%, 3% and 4% of their time, respectively. In the dry season, as opposed to the wet season, the colobus increased the time they spent feeding, traveling, and being alert, and decreased the time they spent resting. General activity levels and group sizes are low compared to those for other populations of Colobus spp. We suggest that Peters’ Angola black-and-white colobus often live (including at our study site) under low preferred-food availability conditions and, as a result, are adapted to lower activity levels. With East African coastal forest declining rapidly, comparative studies focusing on C. -

All Rights Reserved ii Dedications To my wife, Jen. iii Acknowledgments The research presented herein was made possible by the financial support provided by Primate Conservation Inc., ExxonMobil Foundation, Mobil Equatorial Guinea, Inc., Margo Marsh Biodiversity Fund, and the Los Angeles Zoo. I would also like to express my gratitude to Dr. Teck-Kah Lim and the Drexel University Office of Graduate Studies for the Dissertation Fellowship and the invaluable time it provided me during the writing process. I thank the Government of Equatorial Guinea, the Ministry of Fisheries and the Environment, Ministry of Information, Press, and Radio, and the Ministry of Culture and Tourism for the opportunity to work and live in one of the most beautiful and unique places in the world. I am grateful to the faculty and staff of the National University of Equatorial Guinea who helped me navigate the geographic and bureaucratic landscape of Bioko Island. I would especially like to thank Jose Manuel Esara Echube, Claudio Posa Bohome, Maximilliano Fero Meñe, Eusebio Ondo Nguema, and Mariano Obama Bibang. The journey to my Ph.D. has been considerably more taxing than I expected, and I would not have been able to complete it without the assistance of an expansive list of people. I would like to thank all of you who have helped me through this process, many of whom I lack the space to do so specifically here.
