  1. Significant differentiation in the apolipoprotein(a)/lipoprotein(a) trait between chimpanzees from Western and Central Africa

    Asma Noureen, Claudius Ronke, Mahmoud Khalifa, Michel Halbwax, Anne Fischer, Claudine André, Rebeca Atencia, Rosa Garriga, Lawrence Mugisha, Uta Ceglarek, Joachim Thiery, Gerd Utermann and Konrad Schmidt

    Version of Record online: 3 JUL 2017 | DOI: 10.1002/ajp.22683

    Mean Lp(a) levels in western chimpanzees in Sierra Leone are threefold higher than in central chimpanzees or humans in Central Africa. The underlying genetic architecture of this quantitative trait suggests local adaptive evolution.

  2. The Critically Endangered western chimpanzee declines by 80%

Williamson, Roger Mundry, David Brugière, Genevieve Campbell, Heather Cohen, Emmanuel Danquah, Laura Ginn, Ilka Herbinger, Sorrel Jones, Jessica Junker, Rebecca Kormos, Celestin Y. Kouakou, Paul K. N'Goran, Emma Normand, Kathryn Shutt-Phillips, Alexander Tickle, Elleni Vendras, Adam Welsh, Erin G. Wessling and Christophe Boesch

    Version of Record online: 3 JUL 2017 | DOI: 10.1002/ajp.22681

    Pan troglodytes verus has declined by 80% over 24 years due poaching and habitat loss, its range was reduced by 20% from 657,600 to 524,100 km2, and about 35,000 chimpanzees now remain.

  3. The effect of infant vocalization in alloparental responsiveness of common marmosets (Callithrix jacchus)

    Maricele Nascimento Barbosa, Maria Teresa da Silva Mota and Marcela Nascimento Barbosa

    Version of Record online: 20 JUN 2017 | DOI: 10.1002/ajp.22682

    The newborn vocalization affects the behavioral and hormonal response of non-reproductive animals. In both sexes, cortisol levels were significantly higher following infant vocalization exposure.

  4. High reproductive effort is associated with decreasing mortality late in life in captive ruffed lemurs

    Morgane Tidière, Jean-François Lemaître, Guillaume Douay, Mylisa Whipple and Jean-Michel Gaillard

    Version of Record online: 13 JUN 2017 | DOI: 10.1002/ajp.22677

  5. Infant titi monkey behavior in the open field test and the effect of early adversity

    Rebecca H. Larke, Alice Toubiana, Katrina A. Lindsay, Sally P. Mendoza and Karen L. Bales

    Version of Record online: 12 JUN 2017 | DOI: 10.1002/ajp.22678

    Behavior in the open field was affected by age, sex, and early experience. Infant titis made few behavioral distinctions between the attachment figure and other family members. Infants that had adverse early experience showed accelerated maturation.
