    1. Factors of influence and social correlates of parturition in captive Campbell's monkeys: Case study and breeding data

      Alban Lemasson, Ronan Jubin, Philippe Bec and Martine Hausberger

      Version of Record online: 14 FEB 2017 | DOI: 10.1002/ajp.22632

      Based on breeding data with captive Campbell's monkeys, we found a female-biased sex-ratio as well as a non-random seasonal, weekly, and daily timing of parturition. We also describe a Campbell's monkey birth and its social consequences.

    2. Impacts of habitat loss and fragmentation on the activity budget, ranging ecology and habitat use of Bale monkeys (Chlorocebus djamdjamensis) in the southern Ethiopian Highlands

      Addisu Mekonnen, Peter J. Fashing, Afework Bekele, R. Adriana Hernandez-Aguilar, Eli K. Rueness, Nga Nguyen and Nils Chr. Stenseth

      Version of Record online: 9 FEB 2017 | DOI: 10.1002/ajp.22644

    3. Socially transmitted diffusion of a novel behavior from subordinate chimpanzees

      Stuart K. Watson, Lisa A. Reamer, Mary Catherine Mareno, Gillian Vale, Rachel A. Harrison, Susan P. Lambeth, Steven J. Schapiro and Andrew Whiten

      Version of Record online: 7 FEB 2017 | DOI: 10.1002/ajp.22642

      Behaviors seeded by subordinate (but not dominant) chimpanzees were copied by observers.

      This finding contrasts with prior work suggesting social learning bias toward dominant chimpanzees.

    4. Seminal coagulation and sperm quality in different social contexts in captive tufted capuchin monkeys (Sapajus apella)

      Julianne S. Lima, Danuza L. Leão, Karol G. Oliveira, Adriel B. Brito, Wlaisa V. Sampaio, Regiane R. Santos, Helder L. Queiroz and Sheyla F. Domingues

    5. Individual differences in zoo-housed squirrel monkeys' (Saimiri sciureus) reactions to visitors, research participation, and personality ratings

      Zita Polgár, Lara Wood and Marie J. Haskell

      Version of Record online: 2 FEB 2017 | DOI: 10.1002/ajp.22639


      • Squirrel monkey personality ratings correlated with response to visitors and research participation.
      • Monkeys approached a viewing window more when visitors were present.
      • Personality differences in research participation may cause selection bias.


    1. Total energy expenditure in captive capuchins (Sapajus apella)

      Version of Record online: 19 JAN 2017 | DOI: 10.1002/ajp.22637

      We propose a scheme to define and classify planning units across landscapes to guide management practices for a Brazilian titi, Callicebus coimbrai. The scheme is reproducible for other species and locations, according to their specific requirements.

      Description of a new species of Hoolock gibbon (Primates: Hylobatidae) based on integrative taxonomy

      Peng-Fei Fan, Kai He, Xing Chen, Alejandra Ortiz, Bin Zhang, Chao Zhao, Yun-Qiao Li, Hai-Bo Zhang, Clare Kimock, Wen-Zhi Wang, Colin Groves, Samuel T. Turvey, Christian Roos, Kristofer M. Helgen and Xue-Long Jiang

      Version of Record online: 10 JAN 2017 | DOI: 10.1002/ajp.22631

      Based on morphological and genetic characteristics, we describe a new species of hoolock gibbon (Hoolock tianxing) that is distributed between the Irrawaddy-Nmai Hka Rivers and the Salween River, which is previously assigned to H. leuconedys.

    2. Analysis of sea almond (Terminalia catappa) cracking sites used by wild Burmese long-tailed macaques (Macaca fascicularis aurea)

      Tiago Falótico, Noemi Spagnoletti, Michael Haslam, Lydia V. Luncz, Suchinda Malaivijitnond and Michael Gumert

      Version of Record online: 5 JAN 2017 | DOI: 10.1002/ajp.22629

      Long-tailed macaques create clusters of sea almond cracking sites around the trees, using stone tools that are among the heaviest used by the macaques. The tool accumulations in the intertidal region appears to be affect by tides.

      Fluid dipping technology of chimpanzees in Comoé National Park, Ivory Coast

      Juan Lapuente, Thurston C. Hicks and K. Eduard Linsenmair

      Version of Record online: 21 DEC 2016 | DOI: 10.1002/ajp.22628

      Chimpanzees in Comoé National Park use specialized stick tools to collect water from tree holes (WDTs). WDTs are significantly different from tools used to gather honey. The use of WDTs is widespread across neighboring communities in the park.
