The authors examined multiple lemur species to understand the strength and direction of lateralization. They found evidence supporting the &quot;cognitive simplicity&quot; hypothesis and found that individual hand preference was variable, consistent with previous research.</p> <p>Congratulations Carly and Jessica!</p> <p>Look out for this publication in the American Journal of Physical Anthropology!</p> <p><strong>Abstract Objectives</strong>: Asymmetrical behavior patterns are observed in many animal species, but the potential adaptive significance of lateralization and the evolutionary forces driving it remain unclear. Most laterality studies have focused on a single species, which makes interspecies comparisons difficult. The aim of this study was to examine differences in the strength and direction of lateralization in multiple lemur species when engaged in a standardized, novel cognitive task.</p> <p><strong>Materials and Methods</strong>: We assessed laterality in seven lemur species at the Duke Lemur Center when using a novel puzzle-box. We recorded which hand opened the apparatus door and which hand picked up the food reward. We also recorded whether the mouth was used for either action instead of the hands. We then calculated handedness indices (HI), z-scores, and mouth-use rates.</p> <p><strong>Results</strong>: Overall, 62% of individuals were more lateralized than chance. However, within-genera, there were relatively equal numbers of individuals with a left- or righthand bias, which resulted in ambipreference at the genus level. The hand a lemur used on its first success in the task predicted its overall HI value, and the strength of lateralization increased as the number of successes increased. Varecia had significantly higher mouth-use rates than all other genera.</p> <p><strong>Discussion</strong>: We found evidence of an individual learning trajectory in which the hand used on a lemur&#39;s first success was canalized as the preferred (and lateralized) hand, in support of the &ldquo;cognitive simplicity&rdquo; hypothesis. Individual variability in hand preference was high, which is consistent with previous research. Between-genera differences in mouth use appear to reflect species-specific feeding postures and differences in manual dexterity</p> New Publication: Detection of neopterin in the urine of captive and wild platyrrhines by Alexandra Sacco, Jessica Mayhew, Mrinalini Watsa, Gideon Erkenswick, and April Binder, 03 Mar 2020 17:14:26<p>Congratulations to Alex Sacco on her first publication and co-authors:&nbsp;Jessica Mayhew (CWU PBE Professor), Mrinalini Watsa, Gideon Erkenswick, and April Binder (CWU Biology Professor).&nbsp;</p> <p>The authors explored neopterin as a non-invasive biomarker for health assessments in wild alloprimates in South America and confirmed that neopterin is measurable in urine. These findings promote the future use of UNC as an effective, affordable, non-invasive biomarker for field primatologists.</p> <p></p> <p>-------------------------------------------------------------------------------------------------------------------------------------------------------------------</p> <p>Background</p> <p>Non-invasive biomarkers can facilitate health assessments in wild primate populations by reducing the need for direct access to animals. Neopterin is a biomarker that is a product of the cell-mediated immune response, with high levels being indicative of poor survival expectations&nbsp;in some cases. The measurement of urinary neopterin concentration (UNC) has been validated as a method for monitoring cell-mediated immune system activation in multiple catarrhine species, but to date there is no&nbsp;study testing its utility in the urine of platyrrhine species. In this study, we collected urine samples across three platyrrhine families including small captive populations of&nbsp;Leontopithecus rosalia&nbsp;and&nbsp;Pithecia pithecia, and larger wild populations of&nbsp;Leontocebus weddelli,&nbsp;Saguinus imperator, Alouatta seniculus, and&nbsp;Plecturocebus toppini,&nbsp;to evaluate a commercial enzyme-linked immunosorbent assay (ELISA) for the measurement of urinary neopterin in platyrrhines.</p> <p>Results</p> <p>Our results revealed measured UNC fell within the sensitivity range of the assay in all urine samples collected from captive and wild platyrrhine study species via commercial ELISA, and results from several dilutions met expectations. We found significant differences in the mean UNC across all study species. Most notably, we observed higher UNC in the wild population of&nbsp;L. weddelli&nbsp;which is known to have two filarial nematode infections compared to&nbsp;S. imperator, which only have one.</p> <p>Conclusion</p> <p>Our study confirms that neopterin is measurable via commercial ELISA in urine collected from captive and wild individuals of six genera of platyrrhines across three different families. These findings promote the future utility of UNC as a promising biomarker for field primatologists conducting research in Latin America to non-invasively evaluate cell-mediated immune system activation from urine.</p> New Publication: A new identification of the monkeys depicted in a Bronze Age wall painting from Akrotiri, Thera, 08 Dec 2019 19:43:55<p>A new identification of&nbsp;the&nbsp;monkeys depicted in&nbsp;a&nbsp;Bronze Age wall painting from&nbsp;Akrotiri, Thera</p> <p>Marie&nbsp;Nicole&nbsp;Pareja&nbsp;&middot; Tracie&nbsp;McKinney&nbsp;&middot; <strong>Jessica&nbsp;A.&nbsp;Mayhew</strong>&nbsp;&middot; Joanna&nbsp;M.&nbsp;Setchell&nbsp; &middot; Stephen&nbsp;D.&nbsp;Nash&nbsp; &middot; Ray&nbsp;Heaton</p> <p>Director of the PBE Program, Dr. Jessica Mayhew, has a new publication out in the journal <i>Primates</i>: &quot;A new identification of&nbsp;the&nbsp;monkeys depicted in&nbsp;a&nbsp;Bronze Age wall painting from&nbsp;Akrotiri, Thera&quot;. The&nbsp;authors identified a depiction of a monkey on an Aegean style wall painting and determined a new source of monkey iconography. Importantly, this paper emphasizes the need for collaborative approaches between disciplines in order&nbsp;&quot;to answer both new and previously unanswerable questions.&quot; This collaborative group of scholars&nbsp;included&nbsp;a team of primatologists (Dr. Mayhew), a taxonomic illustrator, and an art historian/archaeologist. Thanks to their integrative&nbsp;approach they &quot;identifed species-indicative visual characteristics&quot; of the depicted monkey, thought to be&nbsp;either gray or Hanuman langurs (Semnopithecus sp.).

In this 2nd paper of their series, Coggeshall and co-authors Bolt, Russell, Jacobson, Merrigan-Johnson, and Schreier examine how forest edge habitat influences the vocalizations of howler monkeys (<em>Alouatta palliata</em>). They found that howling was longer in forest zones that are richer in vegetation compared to those forest edges that have been anthropogenically effected. This gives future researchers one more thing to consider in their work: edge effects.</p> <p>Check out the new pub on&nbsp;<em>Behaviour</em>&#39;s website: <a href="" target="_blank">Howling by the river: howler monkey (<em>Alouatta palliata</em>) communication in an anthropogenically-altered riparian forest in Costa Rica</a></p> CSNW News: Almost Human by Zoe Branch, 26 Nov 2019 13:10:40<p>Find the article here:&nbsp;</p> <p></p> <p>A wonderful article published in 425 magazine highlights our beloved Chimp Sanctuary NorthWest!&nbsp;Explore the world of CSNW, learn about the roles that&nbsp;CWU students and staff play, meet the founders (CWU MSc alumns) Diana Goodrich and J.B.
